Maintenance

Troubleshooting

• 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                                   Brand 

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.

• Servicing the tool shall be carried out every 3 months 

only in a                                Authorized Service Center. 

Service and maintenance carried out by not certified 

people mat y be dangerous and can cause severe personal 

injuries as well as making the product Warranty void.

•  Malfunction in the tool caused by no using the 

recommended dose of lubrication, or not complying with 

this Instructions, or repairs carried out by people not 

certified by                                 will not be covered with 

the Warranty.  We reserve the right to carry out technical 

improvements without notice.

Lubrication

Service

The tool runs too 

slow or is not 

working.

The tool rotor turns 

without auctioning 

the trigger.

• Grit or rubber on the tool.

•  The tool has no oil.

• Low air pressure.

• The hose is leaking.

• Pressure drops.

• Ripped rotor blade.

• There is humidity coming out 

through the tool exhaust.

• The “O” ring in the inlet is broken.

• 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                               Authorized Service.

• Water in the tank (See the air compressor Instructions 

Manual). Oil the tool and let it run until the water stops. Oil 

again the tool and run it 1 to 2 seconds.

• Replace the broken “O” ring.
