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
