Operating Instructions and Parts List, Form No. 1000031
OPERATING INSTRUCTIONS
Insert material to be cut between blades.
If part to be cut is very long, open cutter head by pulling out pull pin assembly, slide cutter over
part and close head, locking in place with pull pin assembly fully engaged.
Pump lever handle to close bottom blade on material.
After a few strokes, a slight click will be heard indicating that the pump has shifted into the high-
pressure stage. Continue pumping lever until material has been cut.
To retract piston, lift lever handle slightly and rotate handle clockwise until it stops. Push handle
downward until pressure release plunger has been depressed and piston retracted. Lifting lever
slightly at any time will stop piston retraction.
Note:
After extended use or cutting hard materials, blades will become worn and pitted. Kit No. 4-1235
is available from the factory for blade replacement. Replace worn or damaged blades to maintain
safe, efficient cutting operations.
Blade Replacement
(Kit No. 4-1235)
To replace top blade, withdraw pull pin assembly and open top support. Remove slotted screw
and top blade. Insert new top blade with flat side facing bottom blade and secure with new
slotted screw and lockwasher.
To replace bottom blade, advance piston until bottom blade screw is exposed. Remove hex socket screw and bottom
blade. Insert new bottom blade with flat side facing top blade and secure with new screw.
Close top support and replace pull pin assembly. Cutter is now ready for use.
PERIODIC MAINTENANCE:
Occasionally lubricate pull pins and pivot pins with a molybdenum disulfide grease. The greatest single cause of
failure for hydraulic tools is dirt. Extreme caution should be used to prevent the entry of contaminant's into the unit.
Internal Relief Valve
If cutter fails to cut properly when blades appear to be in good condition, the internal relief valve may have lost its
proper setting (See “Pressure Gage Port”)
Pressure Gage Port
This cutter features a port for the installation of a gage to determine the high-pressure relief valve setting. (See 4-
0790 Gage Assembly)
Oil Leaks
A slight weeping of oil from the ram and pump seals is normal and required to keep moving parts lubricated.
Excessive leakage indicates a need for seal replacement.
Seal Replacement
Maintenance and repairs of this type should only be preformed by properly trained personnel in repair shops under
clean conditions. In addition to all parts shown on keyed parts list, 4-1161 Seal Kit and 4-1065 are available for
replacing seals in the cutter head sub-assembly and in the pump mechanism sub-assembly.
