1. Use the correct tool for the job. This tool was designed for a specific

function. Do not modify or alter this tool or use it for an unintended

purpose.

2. Do not use the tool if any parts are damaged, broken or misplaced.

Repair or replace the parts.

3. Before using this tool, make sure you know the work area and material

you are working on. Make sure you do not accidentally puncture pipes,

pressurized containers or electrical cables.

4. Keep hands and other body parts away from the needles to avoid injury.

5. Only use with accessories rated to handle the forces exerted by this

tool during operation. Accessories not designed for the forces

generated may break and forcefully launch pieces.

6. The needles will become hot while scraping. Allow the needles to

completely cool before touching.

7. Replace needles that are worn or blunt at the cutting edge or shank. A

damaged needle may damage the air needle scraper, reduce efficiency

and increase vibration. A needle that breaks during use can cause an

injury.

8. Do not cover the air vents.

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.

7. Turn OFF the valve and discharge any remaining air pressure after each

use or before adjusting the tool.

8. Do not leave the air tool unattended with its compressed air supply on.

Turn off the compressed air supply and bleed the air tool of any

remaining compressed air before leaving the air tool unattended.

9. Serious injury may occur from loose debris being propelled at high speeds

from the compressed air stream. Always wear OSHA approved 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.

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. Avoid unintentional starts. Ensure the switch is off when connecting to

the power source.

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. Only use an accessory that exceeds the Blows Per Minute rating (see

Specifications). Ensure the accessory is tightly installed.

6. Before using the tool on a workpiece, test the tool by running it at the

highest no load speed for at least 30 seconds in a safe position. Stop

immediately if there is any abnormal vibration or wobbling. Check the

tool to determine the cause.

7. Do not place the tool down until the tool’s accessory has stopped moving.

The accessory may catch the surface of work material and wrench itself

free, causing injury to the user or others in the work area.

8. Hold the tool by the insulated gripping surfaces when performing an

operation where the tool may contact hidden electrical wiring. The

tool’s exposed metal surfaces may convey a shock to the operator from

AIR HOSE PRECAUTIONS

1. Inspect the tool's air hose for cracks, fraying or other faults before

each use. Discontinue use if the air hose is damaged or hissing is heard

from the air hose or couplers. 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.

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.

4. DO NOT use this tool before consulting a physician if one of the

following applies:

UNPACKING

WARNING! Do not operate the tool if any part is missing. Replace the

missing part before operating. Failure to do so could result in a malfunction

and personal injury.

Remove the parts and accessories from the packaging and inspect for damage.

Make sure that all items in the contents are included.

Contents: • Needle Scaler • Needles

ASSEMBLY & INSTALLATION

Numbered references in parenthesis (#1) refer to the included Parts List.

The air needle scaler is preassembled.

INSTALL AIR COUPLER PLUG

Prepare a standard 1/4 in. NPT coupler plug (sold separately) for use with

your tool.

1. Wrap the external threads of the coupler plug with sealant tape.

a. Wrap tape in a clockwise direction so it will not unravel.

b. Do not tape all the threads. Leave several leading threads

unwrapped for easier alignment.

2. Screw the coupler plug into the tool's air inlet and tighten with a

wrench until snug.

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.

OPERATION

1. Ensure the regulator switch is in the neutral or OFF position.

2. Connect the tool to the air source.

3. Turn the compressor regulator to the desired air pressure (see

Specifications).

4. Grip the tool with both hands. Place one hand on the needle housing

(#11) and the other hand on the tool body.

5. Press the trigger lever (#16) to operate. Make sure the needles are not

touching the workpiece surface until the tool is running.

6. Place the vibrating needles on the work surface. Move the needle

scaler around in the area from which you wish to remove the material.

7. Apply light pressure on the tool while in use. Heavy pressure can

damage the work surface.

8. Do not hold the needle scaler in any one area of the work surface for

more than a few seconds. Longer intervals could damage the surface.

9. If the needle scaler will not remove the material from the surface after

a few brief attempts, do not continue. Use another method to remove

the material.

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

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

11. Clean the tool of accumulated dust or debris before storage.

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.

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 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.

REPLACING THE NEEDLES

Replace any needles that are worn down, chipped or damaged.

1. Remove the needle housing (#11) by rotating it counterclockwise.

2. Remove the needle seat (#10) and needles (#9) from the needle

housing.

3. Pull the needles from the needle seat.

4. Insert replacement needles into the vacant holes in the needle seat.

5. Place the needle assembly back into the needle housing.

6. Remount the needle housing to the tool by rotating clockwise. Make

sure that the needle housing is installed tight and secure.

WARNING! Only use replacement needles that have an BPM rating equal to

or greater than the tool (see Specifications). A subpar needle can break and

shatter and may cause an injury to yourself or a bystander.
