POWER TOOL PRECAUTIONS

Tool accessory is a general term that refers to drill bit, saw or cutting

blades, grinding wheel, etc. as appropriate for the tool.

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. Do not cover the air vents.

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

4. 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.

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

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

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

tool. Ensure the accessory is tightly installed.

7. Never touch the tool accessory or workpiece during or immediately

after use. They may be hot and could inflict a burn injury.

8. Never use a tool with a cracked or worn tool accessory. Change the

tool accessory before using it.

GRINDING TOOL PRECAUTIONS

WARNING! Some surfaces contain materials which can be toxic. When

working on materials that may contain lead, asbestos, copper chromium

arsenate or other toxic materials, extra care should be taken to avoid

inhalation and minimize skin contact.

1. Only use a grinding accessory that exceeds the maximum RPM of the

tool (see Specifications).

2. Only use a grinding accessory with the correct shaft size and shape.

3. Ensure the grinding attachment does not have wear or chipping.

Replace if necessary.

4. Before using the tool on the workpiece, run the tool at the highest

speed, without a load, for at least 30 seconds in a safe position. Stop

materials. Keep up-to-date fire-prevention safety instructions in the

event of a fire.

6. Do not use a coolant or water with this die grinder.

7. Do not use as a fixed grinder.

KICKBACK PRECAUTIONS

Kickback is a sudden reaction to a pinched or snagged grinding accessory.

The tool kicks out and away from the workpiece while the grinding

accessory is still active. This can inflict a serious injury on the user or a

bystander. Kickback can also damage the tool or workpiece.

Kickback can be avoided by taking proper precautions:

1. Maintain a firm grip on the tool and position your body and arms to allow

you to resist a kickback. Kickback will propel the tool in the direction

opposite to the grinding accessory’s direction of rotation. A snagged

grinding die may pull the tool out of the grasp of the user.

2. If kickback occurs, the accessory may:

a. pass over a body part, causing a seriously injury;

b. wrench the user’s arm causing muscle or joint injuries; and

c. strike bystanders.

3. Use clamps or a vice to hold down smaller workpieces.

4. Use special care when working on corners, sharp edges or flexible

material. These workpieces have a tendency to snag the grinding

accessory.

5. Only use grinding accessories designed for the tool.

6. Support large panels to minimize the risk of pinching the grinding

accessory. Large panels may sag under their own weight.

VIBRATION PRECAUTIONS

1. This tool vibrates during use. Repeated or long-term exposure to

vibration may cause temporary or permanent physical injury. Take

frequent breaks when using the tool.

2. If you feel any medical symptoms related to vibrations (such as

tingling, numbness, and white or blue fingers), seek medical attention

as soon as possible.

3. Wear suitable gloves to reduce the effects of vibration.

3. Run the compressor at a low volume and check the connection for air

leaks. Do not use the tool until all air leaks are repaired or the faulty

component is replaced.

IMPORTANT! Vibration may cause failure if a quick coupler is connected directly

to the air tool. To overcome this, connect a leader hose to the tool. A quick

coupler may then be used to connect the leader hose to the air line hose.

INSTALL THE GRINDING ACCESSORY

1. Insert the small wrench (#31) onto the spindle (#26) flats to prevent it

from moving.

2. Insert the large wrench (#32) over the collet nut (#30) flats.

3. Turn the large wrench counterclockwise to loosen the collet nut while

holding the small wrench in place.

4. Loosen the collet nut, but do not remove. This allows the collet’s arms

to spread apart.

a. Remove the collet nut if replacing the collet (#29) as well.

5. Insert the grinder accessory shaft into the collet. Make sure it is fully

seated.

6. Hand-tighten the collet nut, then finish tightening with the wrenches.

OPERATION

1. Clean the die grinder of packing grease before first use. Also grease the

spindle gears. See the Air Tool Lubrication section for instructions.

2. Install the grinding accessory (See Assembly & Installation). The type

of grinding accessory installed will depend on the material and task.

3. Connect the tool to the air source.

4. Set the compressor to the correct air pressure and flow (see

Specifications). Start the compressor.

5. Push the trigger lever safety (D) forward to free the trigger lever (E).

6. Wait until the grinding accessory has reach full speed before applying

it to the material

7. Test the tool under no load to confirm the grinding accessory is

installed correctly.

8. Apply the grinding accessory against the material so the debris is

moved away from the work area. Do not press down too hard, as this

can cause the accessory to slow or gouge the workpiece.

9. Lift the die grinder from the material and slowly release the trigger lever.

The trigger lever safety will automatically snap back into place.

10. Wait for the grinding accessory to stop before placing the tool down.

11. Shut the compressor off once the task is completed. Squeeze the

trigger to release residual compressed air from the hose and tool.

Disconnect the tool.

PRESSURE DROP

Apply the air consumption and pressure rate numbers to the tool’s air inlet,

not the compressor’s outlet. Calculate the pressure drop for your air supply

set-up and increase the compressor outlet pressure to compensate. Make

sure you do not exceed the maximum pressure for any part of your air

supply system.

Installing a pressure gauge at the tool inlet is the best way to measure the

air pressure and adjust the compressor’s output.

GRINDING ATTACHMENTS

Die grinder dies and attachments are designed to polish and shape surfaces.

Some attachments can be used on any material while others are designed

specifically for wood, plastic or metal. Consult the manufacturer’s information

to determine the correct use of the grinding attachment.

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. Verify the die grinder’s speed with a tachometer to ensure it does not

exceed the maximum speed. Have the tool repaired if the max. speed is

higher than the no load speed in Specifications.

4. Follow instructions for lubricating and changing accessories.

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

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

8844094 Air Die Grinder V1.0

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

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

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

replacements.

8. Keep the vent passages clear of accumulated dirt, dust, and oil.

9. Clean the tool after each use.

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 male coupler plug

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.

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.
