Maintenance - Greenlee fairmont H8508 Instruction Manual

Maintenance

• Inspect tool before use. Replace any worn,
damaged, or missing parts. A damaged or
improperly assembled tool can malfunction,
injuring nearby personnel.
• Inspect hydraulic hoses and couplings every
operating day. Repair or replace if leakage,
cracking, wear or damage is evident. Damaged
hoses or couplings can fail resulting in injury or
property damage.
Use this maintenance schedule to maximize the tool's
service life.
Notes: Keep all decals clean and legible, and replace
when necessary.
When disposing of any components (hydraulic hoses,
hydraulic fluid, worn parts, etc.), do so in accordance
with federal, state, and local laws or ordinances.

Daily
1. Wipe all tool surfaces clean.
2. Inspect the hydraulic hoses and fittings for signs
of leaks, cracks, wear, or damage. Replace if
necessary.
3. Install dust caps over the hydraulic ports when the
tool is disconnected.
Monthly
Perform a thorough inspection of the hydraulic hoses
and fittings as described in publication 999 3032.3,
SAE J1273 (Hose and Hose Assemblies).
Quarterly
Remove the hammer case cap, anvil, impact mechanism
assembly, spacer, washers and thrust bearing. Clean
the grease from the inside of the handle cavity and all
impact components. Apply a coat of grease (Mobile
Grease HP) to thrust washers (48319), thrust bearing
(48318), hammers (48345), hammer pins (48346) and
anvil (48347) or (48397). Pack the hammer frame center
space before pushing the anvil into the grease pocket.
Reassemble components and tighten hammer case cap
(48516) securely. If wrench is used under severe
operating conditions or hard-duty cycle, mechanism may
need to be greased more often.
Semi-Annually
Drain the hydraulic system fluid. Flush out the hydraulic
system and fill with new, clean fluid. However, if the fluid
turns dark or becomes milky colored, it should be
changed as soon as possible.
