MAINTENANCE

WARNING:

When servicing, use only identical replacement parts.

Use of any other parts could create a hazard or cause

product damage.

WARNING:

Always wear eye protection with side shields or goggles

marked to comply with ANSI Z87.1. Failure to do so could

result in fluids entering your eyes resulting in possible

serious injury.

WARNING:

Disconnect the tool from the air supply before perform-

ing maintenance. Failure to do so could result in serious

personal injury.

GENERAL MAINTENANCE

Avoid using solvents when cleaning plastic parts. Most

plastics are susceptible to damage from various types of

commercial solvents and may be damaged by their use. Use

clean cloths to remove dirt, dust, oil, grease, etc.

WARNING:

Do not at any time let brake fluids, gasoline, petroleum-

based products, penetrating oils, etc., come in contact

with plastic parts. Chemicals can damage, weaken or

destroy plastic which may result in serious personal injury.

LUBRICATION

Frequent, but not excessive, lubrication is required for

best performance. Oil for pneumatic fastening tools added

through the air line connection will lubricate the internal parts.

Do not use detergent oil or additives as these lubricants will

cause accelerated wear to the seals and bumpers in the

tool, resulting in poor tool performance and frequent tool

maintenance.

COLD WEATHER OPERATION

For cold weather operation, near and below freezing, the

moisture in the air line may freeze and prevent tool operation.

We recommend the use of air tool lubricant or permanent

antifreeze (ethylene glycol) as a cold weather lubricant.

CAUTION:

Do not store tools in a cold weather environment to pre-

vent frost or ice formation on the tools’ operating valves

and mechanisms that could cause tool failure and pos-

sible injury.

NOTE: Some commercial air line drying liquids are harmful

to “O” rings and seals. Do not use these low temperature

air dryers without checking compatibility.

AIR SUPPLY PRESSURE AND VOLUME

Air volume is as important as air pressure. The air volume

supplied to the tool may be inadequate because of under-

size fittings and hoses, or from the effects of dirt and water

in the system. Restricted air flow will prevent the tool from

receiving an adequate volume of air, even though the pres-

sure reading is high. The results will be a slow operation or

reduced driving power. Before evaluating tool problems for

these symptoms, trace the air supply from the tool to the

supply source for restrictive connectors, low points contain-

ing water and anything else that would prevent full volume

flow of air to the tool.
