extensions. Use of other accessories can cause them to break, which

could damage the unit or cause injury.

AIR TOOL PRECAUTIONS

1. Use only clean and dry compressed air as a power source.

Contaminated or moist air will gradually damage the tool.

2. Install an in-line shutoff valve or regulator to allow immediate control

over the air supply in an emergency, even if a hose is ruptured.

3. Discontinue tool use if it does not work properly or air is leaking. Tag

or mark the tool as ‘defective’ or ‘out of service’ until repaired.

4. Check the manufacturer’s maximum pressure rating for air tools and

accessories. Compressor outlet pressure must be regulated to never

exceed the maximum pressure rating of the tool (see Specifications).

Exceeding the maximum PSI rating can create a bursting hazard,

causing injury and property damage.

5. Attach all accessories properly to the tool before connecting the air

supply. A loose accessory may detach or break during operation.

6. Never use oxygen, combustible gas or any other bottled gas as a

power source. Any power source other than an air compressor could

cause an explosion and serious personal injury.

safety glasses to protect the eyes during operation of the air

compressor.

10. Always turn off the air compressor and drain tank pressure completely

before attempting maintenance or attaching air tools. Release pressure

slowly from the system.

11. Serious injury or death may occur from inhaling compressed air. The air

stream may contain carbon monoxide, toxic vapors or solid particles.

Never inhale compressed air directly from the pump or air tool.

POWER TOOL PRECAUTIONS

1. Do not use any power tool with a malfunctioning power switch or

control. A power tool that fails to respond to the controls is dangerous

and can cause an injury. A qualified technician must repair and verify

the power tool is operating correctly, before it can be used.

2. Disconnect the power source before installing or servicing the tool.

3. Never force the tool. Excessive pressure could break the tool, resulting

in damage to your workpiece or serious personal injury. Excessive

pressure is the cause if your tool runs smoothly under no load, but

roughly under load.

4. Keep hands and fingers away from the work area. Any part of body

contacting the tool’s working parts could cause an injury.

5. Only use accessories that are specifically designed for use with the

from the air hose or connectors. Replace the defective air hose.

2. Do not allow people, mobile equipment or vehicles to pass over the

unprotected air hose. Position the air hose away from high traffic

areas, in a reinforced conduit or place planks on both sides of the air

hose to create a protective trench.

3. Prevent damage to the air hose by observing the following:

a. Never carry the tool by the air hose.

b. Keep the air hose behind the tool and out of the tool's work path.

c. Keep the air hose away from heat, oil, sharp edges or moving parts.

d. Do not wrap the air hose around the tool as sharp edges may pierce

or crack the air hose. Gently coil the hose and either hang on a hook

or fasten with a device to keep hose together when storing.

4. A damaged or disconnected air hose under pressure may whip around

and inflict personal injury or damage the work area. Secure the

compressor's air hose to a fixed or permanent structure with clamps or

cable ties.

COMPRESSOR/TANK PRECAUTIONS

DANGER! Do not use an air tank beyond its expiration date. A tank rupture

or explosion may kill or cause a serious injury to yourself or a bystander.

Disable and discard the air tank according to the your municipality by-laws.

1. Never drill into, weld, patch or modify the air tank. Immediately

replace the tank or compressor if an air leak develops. The leak may

lead to a rupture.

2. Never make adjustments to the components that control tank pressure.

Serious injury or death may occur if modifications are made to the

pressure switch, safety relief valve or other components that control

the tank pressure.

the opposite direction.

5. Place the socket over the fastener, grip the impact wrench firmly with

both hands and gently squeeze the trigger. The impact wrench will

activate when the trigger is squeezed.

a. If the tool stalls while tightening, do not raise the output pressure

of the air compressor above 90 PSI. Pressure above 90 PSI will

strip the workpiece and damage the tool, potentially causing tool

failure and serious injury. Use other appropriate methods and

tools to tighten the nut.

6. This tool will stop operation/rotation a few seconds after the trigger is

released.

7. When the fastener is tightened, release the trigger and remove the tool

and socket.

8. Use a mechanical torque wrench to check the fastener torque.

9. When finished with the tool, turn off the air compressor, disconnect

the air hose and discharge any residual air remaining in the tool. Put

CARE & MAINTENANCE

1. Maintain the tool with care. A tool in good condition is efficient, easier

to control and will have fewer problems.

2. Inspect the tool fittings, alignment, hoses and power supply cord

periodically. Have damaged or worn components repaired or replaced

by an authorized technician. Only use identical replacement parts

when servicing.

3. Follow instructions for lubricating and changing accessories.

4. Only use accessories intended for use with this tool.

5. Keep the tool clean, dry and free from oil/grease at all times.

6. Maintain the tool’s labels and name plates. These carry important

information. If unreadable or missing, contact Princess Auto Ltd. for

replacements.

WARNING! Only qualified service personnel should repair the tool. An

improperly repaired tool may present a hazard to the user and/or others.

AIR TOOL LUBRICATION

NOTICE! Only use air tool oil to lubricate the tool. Other lubricants are not

suitable and will damage the tool or cause a malfunction during use.

NOTICE! Never use a penetrating oil to lubricate an air tool. Penetrating oil

acts as a solvent that will dissolve the tool’s grease packing and may

damage the o-rings, causing the tool to seize or malfunction.

1. All air tools have an internal coating of grease to prevent corrosion

during shipping and storage. Remove this grease by adding a generous

amount of air tool oil in the air inlet and then run the tool under no

load until the exhaust is clear.

2. Manually add a drop or two of air tool oil into the tool’s air inlet before

each use and after every hour of continuous use. The tool will not work

properly without lubrication and parts will wear prematurely.

3. Avoid adding too much air tool oil as this can cause premature power

loss and eventual tool failure. A qualified technician will need to take

the tool apart and clean out the excess oil.

4. Apply a generous amount of air tool oil to the tool before storing it for

an extended period of time (overnight, weekend, etc.). Run the tool for

approximately 30 seconds to ensure the oil is evenly distributed

throughout the tool. Store it in a clean and dry location.

12 For technical questions call 1-800-665-8685

LUBRICATING ROTOR GEARS

Lubricate the rotor gears and impact mechanism 3 to 4 times a year or more

often if the tool is frequently used.

1. Remove the hex screw (#39) to the grease

opening and set aside.

2. Insert the grease gun nozzle into the opening

and squeeze out several drops of grease.

(Fig. 2-2)

3. Replace the screw and tighten.

4. Run the tool without load for several seconds to spread the grease.

DISPOSAL

Recycle a tool damaged beyond repair at the appropriate facility.

Contact your local municipality for a list of disposal facilities or by-laws for

electronic devices, batteries, oil or other toxic liquids.

IMPORTANT! DO NOT pollute the environment by allowing uncontrolled

discharge of waste oil.
