Maintenance
GOOD SERVICE PRACTICES
Carefully handle all parts, and examine for damage and
wear. Replace parts where required. Always replace
O-rings and Back-up rings when tool is disassembled for
any reason. See applicable Service Kit.
• The efficiency and life of the tool depends on proper
maintenance. Use this manual to better understand
tool and its basic maintenance procedures. Read this
page completely before proceeding with maintenance
and repair. Use proper hand tools in a clean and well-
lighted area; only standard hand tools are required in
most cases. Where a special tool is required, the part
number is given.
• While clamping tool or parts in a vise, and when parts
require force, use suitable soft materials to cushion
impact. For example, use a half-inch brass drift, wood
block, and vise with soft jaws to reduce the possibility
of damaging the tool. Remove components in a
straight line without bending, cocking, or applying
undue force. Reassemble tool with the same care.
• Consult Troubleshooting section of this manual
if a malfunction occurs and then see appropriate
Disassembly, Assembly, and/or Assembly Drawings.
Sealants, Lubricants, & Service Kits
• Smear LUBRIPLATE® 130-AA, or equivalent, on
O-rings and mating surfaces to prevent damage
to O-rings on rough or sharp surfaces, and to ease
assembly. (LUBRIPLATE in a tube, 502723.)
• Each Service Kit contains perishable parts for your
specific tool. As foreseeable use may indicate, keep
extra kits (O-rings, Back-up rings, other standard
items) and tool parts in stock. When stock is depleted,
you can get kit items from any regular retailer of these
items. See Parts List for: O-ring size (AS568- number);
material; durometer. For kit parts lists and related
information, see Kits and Accessories .
PREVENTIVE MAINTENANCE
System Inspection
The operating efficiency of the tool is directly related
to the performance of the complete system, including
the tool with pulling head assembly, trigger, control
cord, and Power Unit. Therefore, an effective preventive
maintenance program includes scheduled inspections of
the system to detect and correct minor troubles.
• Inspect tool and pulling head assembly for external
damage.
• Verify that hose fittings and/or couplings, and/or
electrical connections are secure.
• Observe tool, hoses, and power unit during operation
to detect abnormal heating, leaks, or vibration.
Power Unit Maintenance
Refer to the applicable Power Unit instruction manual.
Tool Maintenance
Whenever disassembled, and at regular intervals
(depending on severity and length of use), replace all
seals, wipers, and Back-up rings in tool. Service Kits,
hoses, and extra parts should be kept in stock. Inspect
cylinder bore, pistons, and piston rods for scored surfaces
and excessive wear or damage. Replace as necessary.
Pulling Head Maintenance
Clean the pulling head assembly often. Dip it in mineral
spirits (Figure 1), or similar solvent, to clean jaws and
wash away metal chips and debris. At regular intervals, as
experience shows, disassemble the pulling head assembly
and use a sharp “pick” to remove embedded particles
from the grooves of the jaws.
WARNING: Inspect tool for damage or wear
before each use. Do not operate if damaged or
worn, as severe personal injury may occur .

CAUTION: Keep dirt and other harmful material
out of air flow system, which includes tool,
hoses, couplers and Power Unit. Parts must be
kept away from unclean work surfaces.
