Disassembly
COMPLETE DISASSEMBLY OF TOOL IS NOT
RECOMMENDED. RETURN TOOL TO YOUR
NEAREST AUTHORIZED GREENLEE DISTRIBUTOR
OR TO THE FACTORY.
When disconnecting tool, removing hydraulic lines,
fittings, or components the following procedure must
be adhered to:
1. Stop the power source.
2. Always wear appropriate personal safety
equipment.
3. Depressurize the hydraulic system.
4. Disconnect hydraulic hoses from tool.
5. Do not remove fittings or components when
hydraulic fluid is hot. Exposure to hot hydraulic
fluid can cause serious personal burns.
6. Remove lines, fittings or components slowly
to release any trapped pressure.
7. If injury results from escaping fluid, see a doctor
at once. Serious reaction or infection may result
if proper medical attention is not obtained
immediately.
Failure to observe these warnings could result in
severe injury or death.
Disassembly procedure is divided into sections of the
tool. Complete disassembly of the tool is seldom
necessary. Disassemble only the area(s) necessary to
correct the problem. See Parts illustrations for
identification of parts as they are removed.
Disassembly should be done on a flat, clean surface.
Some of the parts may fall free during disassembly. To
prevent part loss or damage, keep the tool as close to the
working surface as possible.
Inspect all parts as they are disassembled and mating
parts in the tool that are not removed for signs of
damage, wear, cracks, etc. Replace any parts which
appear to be damaged.
When removing O-rings which must slide over sharp
surfaces, be careful not to damage the O-rings. Use a
rolling motion, and apply hydraulic fluid to ease removal
of O-rings if necessary.
