Installation of the Pacific Powermatic is very simple.  Select a bench or table that will allow comfortable operation from a seated position.  A clear bench area of approximately 36" wide and 24" deep an be considered as a minimum, and additional depth is desirable.  Place loader on bench, centered in the work area, and with the front edge of the base casting even with the front edge of the bench.  The male half of the quick couple hydraulic connections should extend beyond the front of the bench.  The loader may be bolted to the bench with 3/8" bolts or lag screws.  This is not absolutely necessary, and satisfactory operation will be obtained even without the loader fastened to the bench.

The power unit may be placed on a shelf or on the floor under the bench and need not be bolted down.  Make sure there is at least 6" clearance on all sides of the unit and allow adequate ventilation for the motor.  Remove plug in top center of power unit and replace with the attached breather.  Plug must be replaced before unit is transported to prevent loss of hydraulic fluid.

CAUTION:  It is absolutely necessary that the plug is removed and the breather installed when unit is in operation.  Connect the quick-couple hydraulic connectors by pulling movable sleeve back, slipping connector on hose over male portion which is attached to loader and releasing sleeve.  The connectors are color-coded to ensure proper hookup.  Plug motor cord into outlet in switch box on the left side of loader and after making sure the switch is in the off position, plug line cord into any 110-volt outlet adequately wired for 15-18 amp. constant current draw and fused to handle 30 amp. starting loads.

CAUTION:  Extension cords should be avoided when possible.  If extension cord is necessary it must be of #12 wire or heavier and as short as possible.  In no case should extension cord be over 100 ft. or serious overloading of the motor may result.


Your Pacific Powermatic was completely lubricated before testing and adjustment.  Due to the possibility of dust and grit collecting on the lubricated surfaces during shipping, it is suggested that the following lubrication procedure be performed before placing loader into operation for the first time and at the beginning of each loading session thereafter.

1.  With clean cloth wipe old lubrication from column (A).  Wad Guide Bracket Post (B) and Gear Rack (C).  Relubricate these parts with a thin film of "Lubriplate" or similar type lubricant.

2.  Place 1 drop of oil (good grade gun oil or equivalent) on Pivot Bolt of Indexing Cam (D).

3.  Place several drops of oil on Guide Post Bushing (located on the Movable Platen directly at the rear of the loader).

4.  Place 1 drop of oil on each Shell Plate Bearing (E).

5.  Check hydraulic fluid level in power unit.  Fluid level should just cover the plate visible under the filler plug, or approximately 1 1/4" below the upper edge of the filler plug hole.


Operation of the Pacific Powermatic is very simple and can be mastered quickly.  Speed will increase as you become more familiar with the movements necessary for operation.  The hydraulic system does all the heavy labor.  You make only three motions and two fingertip movements of the operating control for a completed reload.

In order to better understand the operating instructions, the following explanation of the functions at each station are given.  There are a total of nine individual size dies which are indexed to a new station for a different operation during each cycle of the loading tool.  Function at each station is as follows:

STATION ONE:  Empty fired case enters size die on the downward movement of the platen and is fully resized including head and rim of case.  Case remains in this size die during entire loading cycle.

STATION TWO:  Case retained in size die is deprimed on the upward movement of the movable platen.

STATION THREE:  Case is reprimed on the downward movement of the movable platen

STATION FOUR:  Case receives accurately metered charge of powder from fully adjustable charge bar on the upward movement of the movable platen.

STATION FIVE:  Wads of any type, including the new shot protector wads, are seated at a predetermined and fully adjustable wad pressure on the upward movement of the movable platen.

STATION SIX:  This is a blank station and no operation is performed on case.

STATION SEVEN:  Case on the upward movement of the movable platen receives metered charge of shot from charge bar that is fully adjustable to throw any amount of shot up to two ounces.

STATION EIGHT:  Crimp is made on case (either paper or plastic cases are crimped in one operation in this station).

STATION NINE:  Completed case is ejected on the upward movement of the movable platen, into container at the rear of the loader.



Efficient operation is dependent upon proper arrangement of components around the loader.  The following suggested layout has been found to be the most convenient for all operators, both left and right handed.

Place a quantity of cases, sorted as to brand, condition and base wad height, in a container to the left of the loader.  Place a Pacific Wad Dispenser, or other suitable container, with correct wads to the right of the loader and approximately 6" from the front of the loading bench.  Place 100 of the proper size primers on the bench to the right of the loader and in front of the wad dispenser.  With the hopper shutoffs in the closed position, fill the left hand hopper with the correct size shot and the right hand hopper with the correct type powder.  Place a container, approximately 6" high and of adequate size to hold ate least 100 shells, directly behind the loader to catch the loaded shells as they are ejected from the loader.  You are now ready to begin actual reloading procedure.


Familiarize yourself with the operation of the Pacific Powermatic by operating it several times without inserting cases or turning on powder or shot.  This will allow you to get the "feel" of the hydraulic control before beginning actual reloading operations.  You will note that platen will stop in any position when you release the hydraulic control.  If loader is stopped for any reason before stroke is completed, you must finish that stroke when operation is resumed.  If stroke is not completed, damage to the loader may result.

In order to begin loading on the Pacific Powermatic, it is first necessary to place loader in cycle.  This is accomplished very simply if the following steps are followed carefully.

1.  Inspect installation to insure proper connection of hydraulic and electrical lines.  Make sure plug is removed from hydraulic unit and breather is installed.

2.  Check component layout to determine that correct components are in the proper place and shot and powder shutoffs are in the off position.

3.  Turn on electrical switch and allow hydraulic unit to run for approximately 1 minute while all hydraulic connections are checked for leaks.

4.  Pull operating lever back and hold until platen reaches top of stroke and pressure relief valve opens, release operating lever and platen will remain in the up position.

IMPORTANT NOTICE:  Opening of the pressure relief valve, which is an integral part of the hydraulic unit, is accompanied by a noticeable change in sound from the power unit.  It is necessary to hold operating lever engaged until the pressure relief valve opens on each stroke of the loader, both up and down.  This insures uniform reloads by maintaining exactly the same pressure for every operation.

5.  Place empty fired case on shell holder post and pus operating lever forward and hold until platen reaches bottom of stroke and pressure relief valve opens.

6.  Pull operating lever back as in step 4.  Place empty case on shell holder post and push operating lever forward.

7.  Pull operating lever back.  Place empty case on shell holder post and proper size primer in primer post cup.  Push operating lever forward to return platen to down position.  Remember to hold operating lever until pressure relief valve opens on every stroke, both up and down.

8.  Turn powder shutoff to on position and repeat step 7.

9.  Place proper wad in wad guide and repeat step 7.

NOTE:  Do not push wad down into wad guide as this will spread the spring fingers making it impossible for them to enter the case mouth and increasing the probability that the spring fingers will be broken.

10.  Place proper wad in wad guide and repeat 7.

11.  Turn shot shutoff to on position and repeat step 10.

12.  Place proper wad in wad guide, pull operating lever back, hold until platen reaches top of stroke and pressure relief valve opens.  Place empty case on shell holder post and proper primer into primer post cup, push operating lever forward and hold until platen reaches full down position.  Always remember to hold operating lever engaged until pressure relief valve opens, both on the upstroke and on downstroke.

The loader is now in cycle and ready for production loading.  The illustrations below depict the three simple movements necessary for operation of the Pacific Powermatic.

CAUTION:  After loading several shells, be sure to cut one or two shells open and check both shot and powder weights to make sure charge bar adjustment is as desired.  This is an extremely important safety measure that should be taken when changing powder charges, and is recommended as a periodic safety check.


1.  With loader in starting position (motor running, platen in down position) operator places wad in wad guide.

2.  Operator pulls hydraulic lever back (1) holding until platen reaches top of stroke, then releasing - platen will remain in up position.  During this operation, the shell plate rotates automatically, ejecting a loaded shell as it goes.  Then, simultaneously (in progressive positions) case is deprimed, powder is dropped, wads are seated at correct pressure, shot is dropped and a perfect crimp is made.

3.  While platen is in up position, operator places on shell holder post (1) and primer in primer post cup (2).  Operator then pushes hydraulic lever forward holding until platen reaches down position, then releasing.  During this operation, one casing is resized including head and rim, and another is primed.  Operator then repeals steps 1 and 2.


The Pacific Powermatic is hydraulically powered and first impression may be that it would be extremely difficult to adjust.  This is not true.  Adjustment of the Powermatic is no more difficult that conventional, manually powered loaders.  The first step in adjusting, as on any loader, is to become completely familiar with proper adjustment procedures.  Before making any adjustments, please read and thoroughly understand the following instructions.

Your Pacific Powermatic was completely adjusted and tested before leaving the factory.  No adjustment should be needed when first placing the unit into operation.

We will cover the adjustment procedure by beginning with the two most frequently made adjustments - Wad Pressure and Crimp.

WAD PRESSURE:  The Pacific Powermatic is designed to provide continuously adjustable wad pressure settings ranging from 30 to 100 lbs.  Wad pressure is read on the scale that extends from the top of the wad pressure assembly, when case with powder and wads is in that station and platen is in the up position.  With the platen in the up position, not the reading on the wad pressure scale and determine if more or less wad pressure is desired.  Adjustment of the wad pressure must be done when the platen is in the down position.  Return platen to down position after inserting empty case and proper primer in their respective positions.  Adjustment is made by loosening lock nut (250-12) and threading wad pressure assembly up to decrease or down to increase wad pressure.  One complete rotation of the wad pressure assembly is equal to approximately 10 lbs. pressure.  When correct adjustment has been reached, tighten lock nut (250-12) to retain this adjustment.

CRIMP:  There are two crimp die bodies furnished with your Pacific Powermatic, a standard crimper for use with fired paper cases and a double acting crimper for plastic cases.  To change from one of these crimpers to the other, it is necessary to remove the 1/4" hair pin clip (9-G27) from the shaft that extends through the crimp die bushing (PM-62), remove the crimper, insert the other style crimper and replace the hair pin clip.  Adjustment of the crimp die must be made when platen is in the down position.  To adjust crimp for depth, either paper or plastic cases (loosen lock nut (250-12) on crimp die bushing (PM-62) and thread bushings down to deepen crimp or up to made a more shallow crimp.  When correct adjustment has been determined, tighten lock nut.

NOTE:  When double-acting crimp die is installed, it must be free to move up and down and also rotate.

CHARGE BAR:  The adjustment of the charge bar must be very precise in order to obtain safe, reliable reloads.  To insure correct adjustment, it is necessary to have access to a high-quality powder scale such as the Pacific Deluxe Scale.  Your Powermatic as received from the factory is adjusted for the load marked on the labels on the ends of the charge bar.  This load should always be checked for weight, as there can be considerable variation between different lots of the same type powder or shot.  To adjust charge bar for other charges, remove labels from end of charge bar.  Turn shutoff valve (PM-78) to the off position (arrow in horizontal position).  Loosen measure lock screw (CL-5) and lift-off measure casting (PM-76).  You will note that charge bar contains a full charge of both shot and powder.  Adjustment can be made without emptying charge bar.  Insert screw driver through charge until it bottoms on piston, rotate slowly until screw driver enters adjustment slot in piston.  Loosen socket head set screw (PM-51 on shot and PM-52 on powder) located in the end of the charge bar.  Thread socket head set screw to retain setting.  Replace measure casting, turn shutoff valve to open position (arrow in vertical position) operate loader several times to settle powder in hoppers, then weight next charge dropped.  If further adjustment is necessary, repeat above procedure until exact charge is secured.

SHELL HOLDER POST:  The shell holder post performs a two-fold operation.  It holds and aligns empty case while it enters size die and also serves as an anvil against which the head of the case is pressed during resizing.  This post was correctly adjusted at the factory and unless the lock nut (SS-5) becomes loose, should never need adjustment.  If adjustment becomes necessary, loosen lock nut (SS-5) on both shell holder post (PM-7) and platen stop (PM-14) and thread them down approximately 2 to 3 turns.  With motor running, push operating lever forward to be sure that platen is in full down position.  Adjust shell holder post up until case enters size die fully and is resized completely, including the rim of the case.  With case still in position in station #1 and platen in full down position, adjust platen stop up until it contacts the bottom of the platen firmly.  Lock both the shell holder post and platen stop in place by retightening lock nuts.

PRIMER SEATER:  The primer seating assembly is adjusted at the factory and should require no further attention.  To adjust primer seater assembly, loosen lock nut (SS-5) at bottom of base and thread entire base up or down to attain the correct adjustment.  When correct adjustment has been reached, retighten lock nut.  After height adjustment has been made, check primer post to make sure it is centered under the die.  To check centering, make sure platen is in full down position, shut off electrical switch, remove size die that is in place directly over primer seating post.  Place primer in cup and measure with calipers or dividers to make sure primer sits dead center under die.  This correct alignment prevents concaving of case head from off-center primers.

WAD GUIDE BRACKET:  Adjustment of the wad guide bracket (PM-43) allows it to be used with all types of wads.  For use with one-piece wad column-shot protector combination wads, adjust wad guide so that when wad is seated on top of spring fingers, the wad pressure ram (PM-53) enters the shot protector approximately 1/16".  For Alcan Combo Wads or two-piece wad columns, wad guide bracket may be adjusted slightly lower to give more finger clearance.  To adjust wad guide bracket (PM-43), loosen set screw in back of wad-guide bracket and slide bracket up or down as necessary.  Retighten set screw to retain bracket in position.

CAUTION:  Do not push wads down into wad guide as this will spread spring fingers making it impossible for them to enter case and causing breakage of the fingers.


Due to the steel head construction of Remington and Peters high brass plastic hunting load cases, it is necessary to have a set of special size dies of larger diameter in order to load them on the Pacific Powermatic.  Size die furnished with the Powermatic are of the correct size for all target load plastic cases and for all paper cases including high brass hunting load cases.

After some use you may find slightly seepage of hydraulic fluid at the unit.  This is normal in all hydraulic systems and unless it becomes excessive is no cause for concern.  Seepage at the threaded joints can be eliminated by removing line and using "Permatex Gasket Sealer" on the threads.  Do not allow the "Permatex" to enter hydraulic system by using this sealer too freely.

A pin is located in the side of the Cam (PM-19).  This pin serves as a stop pin limiting the travel of the cam and also as a shear pin eliminate breakage of other parts of the loader if the turret should become jammed.  If one of these shear pins breaks, determine the cause and clear loader, the with small pin punch, tap broken portion out of cam and replace with spare that was supplied with the loader.

If during operation the Gear Rack (PM-59) is not returning completely to its stops, it is advisable to check for bind.  This may be due to improper lubrication of the rack or looseness of charge bar housing (PM-73) caused by (PM-65) socket set screw being loose.

When changing powder types, turn shutoff valve to off position, loosen set screw and remove measure casting.  Operate loader several times to clear charge bar of shot and powder.  Place spout on measure casting over powder container and open shutoff valve to drain powder.  If powder is poured from top of hopper, enough powder will remain in the shutoff valve to create, under some conditions, a dangerous overload of the next shell reloaded.

After making any adjustments on loader, always make sure that Turret (PM-39) is in its proper relative position before placing loader back into operation.
