Probable Cause
Solution
Dismantle breaker, clean out all ports and air passages.
Keep the air hose in good condition; never use a soft
deteriorated Hose.
Remove valve chest parts from the breaker. Clean parts.
Never use dirty oil or oil that does not conform to the
recommended specifications.
Dismantle breaker to remove Piston. Repair Piston by
placing in a high speed lathe and dressing with fine
emery cloth. Never run breaker without the proper
lubricating oil in the lubricating oil reservoir.
Never allow the air supply to kink or make sharp bends.
As a general rule keep the air supply line
under 50 ft. (15 m).
A 3/4 in. (19.1 mm) diameter air supply is recommended
for the breaker.
Install moisture traps in the air supply line or add
anti-freeze lubricant directly through the air inlet. Use
"KILFROST" anti-freeze lubricant or equivalent.
The air supply pressure at the tool should be 90 to 100 psi
(6.2 to 6.9 bar).
Keep shank fed-up to the work. Always maintain a
constant pressure when operating the breaker.
Dismantle the breaker and clean out all ports and
passages.
Maintain the proper oil level in the lubricating oil reservoir.
Steel shank must show a film of oil.
Remove valve chest parts from the breaker. Clean parts.
Never use dirty oil or oil that does not conform to the
recommended specifications.
Stop operating the breaker and perform initial servicing.
Never run a new breaker at full throttle until a proper
break-in period has been completed.
Keep shank fed-up to work. Always maintain constant
pressure when operating the breaker.
Remove shank piece from breaker.
When pulling steels, always use minimum throttle.
Before operating the breaker make sure the lubricating oil
reservoir is full of proper lubricant.
Use only the recommended lubricating oil.
Dismantle breaker and clean out dirt and gummy residue.
Service the breaker with clean oil. Protect the tool from
dirt when idle.
Blow out air lines. If moisture traps are installed in the air
supply line, drain the moisture.
Clean lubricating oil reservoir and adjust for proper rate
of feed.
