PALADINPERIODIC MAINTENANCE MANUAL

Paladin Periodic MaintenanceDaily

Oil pneumatic port with 5 drops of air-tool oil -OR- Use air-line oiler at 1-drop per hour rate

MonthlyHone blade: WEAR CUT-RESISTANT GLOVES

Unscrew both stroke adjustment knobs

Gently lift ‘head’ I-Beam o� of shear

Set ‘head’ upside down on work bench

Hone �at side of blade with included hone stone

DO NOT HONE BEVELED SIDE OF BLADE

Gently set head back onto pins

Re-install stroke adjustment knobs and lightly tighten

‘Cut’ air to see how far down the blade travels

Tighten stroke adjustment knobs until the blade evenly bites the blade stop when ‘cutting’ air

Grease pins: Coat sliding-contact portions of the steel pins (the outer surfaces of the drive cylinders) with grease

Leak Check: Check for air leaks; tighten or replace tubes and �ttings as necessary

Check for hydraulic leaks, replace �ttings as needed

Re-Balance Cylinders to level out the blade by turning stroke adjustment knobs

Annually

Replace Blade Stop Remove M6 Pan Head Phillips screws from anvil

Remove anvil and blade stop

Discard old blade stop and replace with new

Reinstall anvil and blade stop with M6 Pan Head Phillips screws

DO NOT OPERATE WITH AIR PRESSURE ABOVE 125PSI (8.6 Bar).Hydraulics can easily crush bone - Keep all appendages clear of moving components.

High pressure hydraulic fluid can cut through skin - Cut power and de-pressurize hydraulic system before servicingWear ANSI approved safety gear when operating or bystanding.

Blade Stop

Replace O-Rings in cylinders and pneumatic valve (if needed)

Drive Cylinders WEAR CUT-RESISTANT GLOVES

Unscrew both stroke adjustment knobs

Gently lift ‘head’ I-Beam o� of shear

Set ‘head’ upside down on work bench and cover with a protective layer such as a wooden box or milk crate

Remove springs from shear

Unscrew cylinder feet with two pipe wrenches

Drive piston rod out of each cylinder with a 5/16” diameter punch and dead-blow hammer

NOTE: LARGE AMOUNTS OF HYDRAULIC OIL WILL DRAIN FROM CYLINDERS

Remove old O-Rings from pistons and piston rods

Install new O-Rings on pistons and piston rods (-021 and -012 sizes)

Coat piston and pistons rods with lithium grease

Reinstall pistons into cylinders. You may need to press them into place with a 1” wooden dowel

Reinstall cylinder endcaps with two pipe-wrenches Master Cylinder Remove the 4 screws connecting the table to the tail

Remove the 2 screws near the tail which connect the master cylinder to the table

Turn shear upside-down

Remove 4 screws connecting tail to rails

Disconnect air lines

Remove 4 socket head bolts from master cylinder

Remove master cylinder end cap

Remove master cylinder

Remove piston

Remove old O-Rings from piston and piston rods

Install new O-Rings on piston and piston rods (-349 and -010 sizes)

Coat piston and rods with lithium grease

Reinstall piston, cylinder, endcap, and tail with appropriate fasteners

-12 O Rings

-21 O Rings

-349 O Rings

-10 O Rings

Hydraulic Fluid Filling/Bleeding Procedure Use ISO 32 hydraulic oil or 10W-30 motor oil

Construct two bleed lines by connecting a 1/8” NPT male to 1/8” hose barb to a 1/4” OD x 1/8” ID vinyl tube, cut to about 12” long (included in maintenance kit)

Stand shear on end with cutting side up. Brace as necessary.

Remove the �ll plugs from each cylinder

Connect a bleed line to each cylinder

Put the free end of the bleed lines into a container holding hydraulic oil

Pull and hold the actuator toggle until the cylinder is fully vented, then release. You will notice �uid and bubbles �owing through the bleed lines

Repeat until no more bubbles can be seen in the bleed lines

Coat the �ll plugs with pipe sealant paste

Remove the �ll lines

Reinstall and �rmly tighten the �ll plugs

Pneumatic Valve (replace if leaking)

Remove 3 mounting screws which connect the PV10 valve to the rail

Remove all air �ttings and brass vents from old valve and connect them to the new valve

Mount the new valve using the 3 mounting screws

Re-assemble shear

Re-attach tail

Re-attach table to the master-cylinder block near the tail

Reinstall springs

Reinstall head

Clamp head down (as if the blade were closed) and install adjustment knobs

Bleed cylinders per standard bleeding procedure

Remove and sharpen blade (if dull) The Paladin shear hardwood blade has a primary bevel ground to 30 degrees and 1/32” wide, and a secondary bevel ground to 18 degrees

When the blade is worn, remove it and have it professionally resharpened to the same primary and secondary bevel con�guration
