Maintenance

Lubrication
• Pneumatic tools need constant lubrication along their
useful life and during the operation. Compressed air
needed in the tool to run carry humidity which could
oxidize the motor and bearing in the tool.
To prevent this possibility, it is necessary to constantly
deliver lubricating oil through a
UNI-LL-1/4 centralized filter-oiler system installed between
the air compressor and the tool.
• Any excess of oil in the motor is

immediately expelled through the exceeding oil exhaust.
Keep the exhaust free of obstructions and never point it
towards people or objects.
• If not using the tool for long periods of time, it shall need
to be lubricated with care.
• After 60 hours of operation, the tool mechanism needs a
little greasing. Excessive grease may diminish power.

Solution
• Drain the tool with pneumatic machine oil or rubber
solvent.
• Follow the lubrication instructions to lubricate the tool.
• Adjust the tool regulator in the highest position.
Adjust the compressor regulator to 90 PSI maximum.
• Tighten and seal the hose joints if you find any point of
leak. Use sealing tape.
• Confirm the hose is the right size. Long hoses or tools
using large volumes of air may need a hose with a 1/2"
inner diameter or larger, depending of the total length of
the hoses. Do not use many hoses connected with fast
mount accessories. This drops the additional pressure and
reduces the tool power. Connect hoses directly.
• Take the tool to a
