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, all effective preventive 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 couplings, 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 necessary.
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 per instructions on applicable Nose Assembly Data Sheet.
