MAINTENANCE

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 undersize

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 pressure 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 containing

water and anything else that would prevent full volume flow

of air to the tool.

REQUIRED DAILY CHECKLIST

Disconnect the air supply from the tool and remove all

fasteners.

Check all screws, nuts, bolts, and pins on the tool. If

any of these are loose, they must be tightened with the

appropriate size wrench.

Press the workpiece contact against a workpiece to

ensure that it moves smoothly.

With the workpiece contact depressed, pull the trigger.

The trigger should move smoothly, without binding.

While the tool is not loaded, connect the appropriate air

supply (at 70 psi) to the tool.

 Without pulling the trigger, press the workpiece contact

against a workpiece several times. The tool must not

operate. No air should leak from the tool.

With the workpiece contact not engaged on the

workpiece, point the tool down and away and pull the

trigger several times. Hold the trigger in this position for

a minimum of 5 seconds. The tool must not operate.

Press the workpiece contact firmly against the

workpiece. Pull the trigger. The tool must operate.

With the workpiece contact still depressed, release the

trigger. The driver must return to its up position.

If the tool successfully meets all the requirements in this

checklist, it is ready for use. Load the proper fasteners

for the desired application.

Set the depth of drive according to the Drive Depth

Adjustment section in this manual. Repeat this checklist

before using the tool each day, or if the tool is dropped

or damaged in any way.

WARNING:

When servicing use only identical replacement parts. Use

of any other parts can create a hazard or cause product

damage.

WARNING:

Always wear eye protection with side shields marked to

comply with ANSI Z87.1 along with hearing and head

protection. Failure to do so could result in objects being

thrown into your eyes and other possible serious injuries.

WARNING:

Disconnect the tool from the air supply before performing

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 could result in serious personal

injury.

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

prevent frost or ice formation on the tools’ operating

valves and mechanisms that could cause tool failure and

personal injury.
