tion refer to TROUBLESHOOTING and illustra-
tions.
System Inspection
Operating efficiency of the tool is directly related
to performance of complete system, including
tool with nose assembly, hydraulic
hoses, trigger and control cord, and POWERIG
Hydraulic Unit. Therefore, an effective preven-
tive maintenance program includes scheduled
inspections of the system to detect and correct
minor troubles.
1. Inspect tool and nose assembly for external
damage.
2. Verify that hydraulic hose fittings and cou-
plings, and electrical connections are
secure.
3. Inspect hydraulic hoses for damage.
Replace hoses if damaged. Do not use
hoses to carry tools.
4. Observe tool, hoses and POWERIG
Hydraulic Unit during operation to detect
abnormal heating, leaks or vibration.
POWERIG® Hydraulic Unit
Maintenance
Refer to the applicable POWERIG Hydraulic
Unit Instruction Manual.
Tool Maintenance
At regular intervals, depending upon use,
replace all seals, wipers and back-up rings in
tool. Service Kits and hoses should be kept on
hand. Inspect cylinder bore, piston and piston
rod, and unloading valve for scored surfaces,
excessive wear or damage, and replace as nec-
essary. Always replace seals, wipers and back-
up rings whenever the tool is disassembled for
any reason.
Nose Assembly Maintenance
Nose assemblies with UNITIZED
™
jaws must
be disassembled and cleaned in mineral spirits
or isopropyl alcohol.
Do not let UNITIZED
jaws (urethane) soak in solvent. Do not use
solvents that cause urethane to swell. Dry
components immediately after cleaning.
Use sharp “pick” to remove particles packed in
jaw grooves. Reassemble.
