Working practice when preforming
maintenance
Whenever you are repairing the air nailer, take
care to clean and lubricate the internal parts. Use
Parker "O­Lube" or similar on all O­rings. Coat all
O­rings with O­Lube before reassembling.
Apply oil lightly to all moving surfaces and pins.
Finally, following complete assembly, squirt a few
drops of pneumatic tool lubricant into the air input
fitting, before commencing testing.
Air pressure and volume
Air volume is just as important as air pressure.
The air volume that is delivered to the air nailer
may be insufficient due to defective couplings
and crimped hoses, or through the effect of
contamination and water in the system.
The consequence of a restricted airflow is that
the air nailer receives an inadequate air volume,
even though the air pressure reading is high.
This will lead to defective operation, through
reduced driving power. Before you begin with
troubleshooting, you should first inspect the
path from compressor to air nailer for restricted
connections, twisted hoses and anything else that
might prevent sufficient air from flowing to the
appliance.
Lubrication
Frequent, but not excessive, lubrication is
essential for optimum functioning. Oil injected
from an oil mist lubricator will lubricate the internal
parts continuously. Use a lubricant for pneumatic
tools, Mobil Velocite #10, or equivalent. Use no
cleaning oil or additives, as these lubricants can
cause accelerated wear of seals and edges in the
appliance, resulting in a poor performance and
frequent maintenance of the tool.
