4. Periodic Maintenance (Every 100 hours)
1) Remove the tool and all grease from the tool holder bushing
Do not use a pressure washer, steam, or solvents as they damage the seals. Check for
chips or cracks inside the housing and on the bushing surfaces. Cracks and chips could
indicate that:
(1) Lubrication is insufficient
(2) Grease type is not appropriate
(3) Blank hammering and side loading is occurring and hammer is being operated
improperly.
2) Check wear on tool pin
Examine the shoulders and side surface. If they are worn or deformed, rotate or
replace as required.
3) Check wear on tool holder bushing
Replace tool, tool holder Bushing or both where the combined wear exceeds 5mm. Some
Bushings are grooved to provide even grease distribution. Replace the Bushings when the
grooves are worn through. Excess tool holder Bushing wear causes tool misalignment to
the piston, causing premature hammer failure.
4) Replace damaged or worn parts
Then wipe all components clean, including the
lubrication port. Hand grease the tool shank
and inside the chuck bushings before placing
it back into the hammer.
5. Factors of Tool Life
1) The type of work ( Twisting action )
Breaking reinforced concrete, for instance, is more
detrimental to tool than concrete without rebar.
Twisting action caused by the flat edge of the tool
against the tool and retainers.
2) The type of rock
A particularly abrasive rock will wear the tool out
faster than less abrasive material. Certain types of
rock turn to powder which cushions the impact.
This could cause the tool to overheat and
mushroom.
