Solution
Dismantle the Pickhammer and clean out all ports
and air passages. Keep the air hose in top notch
condition; never use a soft, deteriorated hose.
Remove and clean the valve chest parts. Never
use dirty oil or oil that does not conform to the
recommended specifications. Check for correct
valve assembly procedures.
Repair the piston by placing in a high speed lathe
and dressing with fine emery cloth.
Never run the Pickhammer without the
proper lubricating oil in the lubricator.
Never allow the air hose to kink or make
sharp bends.
As a general rule, keep the air hose length under
15 m (49 ft).
Use a 13 mm (1/2") inside diameter air
supply hose.
Clean the screen in the Inlet Bushing Assembly
The maximum air supply pressure at the tool
should be 6.2 bar (90 psig).
Keep shank fed–up to the work. Always
maintain a constant pressure when operating
the Pickhammer.
Disassemble the Pickhammer and clean out all
ports and passages.
Maintain the proper oil level in the lubricator.
Steel shank must show a film of oil.
Clean the screen in the Inlet Bushing Assembly.
Stop operating the tool and perform initial
servicing. Never run a new Pickhammer at full
throttle until a proper break–in period has been
completed.
Keep shank fed–up to the work. Always
maintain a constant pressure when operating
the Pickhammer.
Remove the shank from the Pickhammer
Use minimum throttle when pulling steels away
from work.
Before operating the Pickhammer, make
sure the lubricating oil reservoir is full of
proper lubricant.
Use only the recommended lubricating oil.
Disassemble the tool and clean out dirt and
gummy residue. Service the Pickhammer with
clean oil. Protect the tool from dirt when idle.
Clean the screen in the Inlet Bushing Assembly.
Install moisture traps in the air supply line or
add anti–freeze lubricant directly through
the air inlet. Use anti–freeze lubricant.
Clean out the air lines. IF moisture traps
are installed in the air supply line, drain
the moisture.
Adjust the lubricator for the proper rate
lubricant feed.
