IMPORTANT SAFETY PRECAUTIONS

WARNING! Read and understand all instructions before using this tool. Keep this manual for

the safety warnings and precautions, operating, inspection and maintenance instructions.

When using this tool, basic precautions should always be followed to reduce the risk of per-

sonal injury and/or damage to the equipment.

WORK AREA

1. Keep your work area clean and well lit. Cluttered and dark areas invite accidents.

2. Operate in a safe work environment. Do not use machines or power tools in damp or wet locations. Do not

expose to rain. Do not use power tools in the presence of ammable gasses or liquids.

3. Keep children, bystanders and visitors away from the work area. Do not let them handle tools, hoses or

extension cords. No one should be in the work area if they are not wearing suitable protective equipment.

4. Store unused equipment. When not in use, tools must be stored in a dry location to prevent rust. Always lock

up tools and keep them out of reach of children.

PERSONAL SAFETY

1. Use eye, face, head, breathing and ear protection. Always wear ANSI approved impact safety goggles, which

must provide both frontal and side protection. Wear a full face shield if your work creates metal lings or wood

chips. Wear an ANSI approved dust mask or respirator when working around metal, wood and chemical dusts

and mists. Wear ANSI approved earplugs.

2. Do not over reach; keep proper footing and balance at all times. Proper footing and balance enables better

control of the tool in unexpected situations.

3. Dress properly, wear protective equipment. Do not wear loose clothing or jewelry as they can be caught in

moving parts. Tie back long hair. Protective, electrically non-conductive clothes and non-skid footwear are rec-

ommended when working.

4. Stay alert, watch what you are doing and use your common sense. Do not operate any machine or tool

when you are tired, under the inuence of drugs, alcohol or medications.

5. Use clamps or other practical ways to secure and support the work piece to a stable platform. Holding the

work piece by hand or against your body is unstable and may lead to loss of control.

TOOL USE AND CARE

1. Use the right tool for the job. Do not attempt to force a small tool or attachment to do the work of a larger

industrial tool. The tool will perform better and safer at the task for which it was intended. Do not modify tools or

use for a purpose for which they are not designed.

2. Maintain tools with care. Keep tools clean, sharp and in good condition for better and safer performance. Fol-

low instructions for lubrication and changing accessories. Inspect tool ttings, alignment and hoses periodically

and, if damaged, have them repaired by an authorized technician or replaced. The handles must be kept clean,

dry and free from oil and grease at all times. A properly maintained tool reduces the risk of binding and is easier

to control. Do not apply excessive force to try to get the job done faster. Applying excessive force can lead to

slips and damage to your work or personal injury.

3. Remove adjusting keys and wrenches. Check that keys and adjusting wrenches are removed from the tool

before connecting to air source. A wrench or key that is left attached to a rotating part of a tool increases the

risk of personal injury.

4. Avoid unintentional starts. Be sure that the throttle is in neutral or OFF position when not in use and before

connecting it to any air source. Do not carry the tool with ngers on or near the switch.

5. Only use the lubricants supplied with a tool or specied by the manufacturer. Other lubricants may not be

suitable and may damage the tool or even make the tool explode.

6. When not in use for an extended period, apply a thin coat of lubricant to the steel parts to avoid rust.

7. Do not use tool if the trigger switch does not function properly. Any tool that cannot be controlled with the

ON/OFF switch is dangerous and must be repaired.

SERVICE

1. Check for damaged parts. Before using any tool, any part that appears to be damaged should be carefully

checked to determine that it will operate properly and perform its intended functions. Check for alignment and

binding of moving parts, broken parts or mounting xtures or any other condition that may affect proper opera-

tion. Any part that is damaged should be properly repaired or replaced by qualied technician.

2. When servicing, use only identical replacement parts. Only use accessories intended for use with this tool.

Replace damaged parts immediately.

AIR SOURCE

1. Disconnect air supply. Disconnect tools from air pressure source when not in use, before cleaning, servicing or

changing a piece or accessory. After disconnecting, discharge any residual air pressure.

2. Use proper size and type of air pressure line and ttings. The recommended air line for this tool is 1/4" NPT

air inlet.

3. Always verify prior to using a tool that the air source has been adjusted to the rated air pressure or

within the rated air pressure range. Over-pressurizing a tool may cause bursting, abnormal operation, break-

age of the tool or serious injury to persons. Use only clean, dry, regulated air at the rated pressure as marked

on the tool.

4. Never use pure oxygen, carbon dioxide, combustible gases or any bottled gas as an air source for a tool.

Such gases are capable of causing an explosion and serious injury to persons. Do not use an air source other

than an air compressor to power this tool.

5. Always use an air regulator and a moisture trap in your compressed air system.

6. Drain the air tank daily. Water in the air line will damage the tool.

7. Clean air inlet lter weekly.

8. Avoid using an unnecessarily long air hose. Choose a hose that is appropriate for the situation, as a hose

that is too long and running across the oor can be more dangerous than helpful.

9. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections

are secure.

10. Always carry a tool by its handle, never carry the tool by the air hose.

11. Line pressure should be increased to compensate for unusually long air hoses over 25 feet. (8 meters).

The hose diameter should be 3/8” I.D.

VIBRATION PRECAUTIONS

Some tools vibrate during use. Repeated or long-term exposure to vibration may cause temporary or permanent physi-

cal injury, particularly to the hands, arms and shoulders.

1. Anyone using vibrating tools regularly or for an extended period should rst be examined by a doctor

and then have regular medical checkups to ensure medical problems are not being caused by or wors-

ened from tool use. Pregnant women or people who have impaired blood circulation to the hands, past hand

injuries, nervous system disorders, diabetes or Raynaud's Disease should not use these tools. If you feel any

medical symptoms related to vibrations (such as tingling, numbness, and white or blue ngers), seek medical

attention as soon as possible.

2. Do not smoke during use. Nicotine reduces the blood ow to the hands and ngers, increasing the risk of

vibration-related injury.

3. Wear suitable gloves to reduce the vibration effects on the user.

4. Use tools with the lowest amount of vibration when there is a choice between different processes.

5. Do not use for extended periods. Take frequent breaks when using these tools.

6. Let the tool do the work. Grip tool as lightly as possible (while still keeping safe control of it.)

7. To reduce vibration, maintain tool as explained in this manual. If abnormal vibrations occur, stop using this

tool immediately.

LUBRICATION

An automatic inline lter-regulator-lubricator is recommended as it increases tool life and keeps the tool in sustained op-

eration. The inline lubricator should be regularly checked and lled with air tool oil. Proper adjustment of the inline lubrica-

tor is performed by placing a sheet of paper next to the exhaust ports and holding the throttle open for approximately 30

seconds. The lubricator is properly set when a light stain of oil collects on the paper. Excessive amounts of oil should be

avoided.

In the event that it becomes necessary to store the tool for an extended period of time (overnight, weekend, etc.), it should

receive a generous amount of lubrication at that time. The tool should be run for approximately 30 seconds to ensure oil

has been evenly distributed throughout the tool. The tool should be stored in a clean and dry environment.

• It is most important that the tool be properly lubricated by keeping the inline lubricator lled and correctly

adjusted. Without proper lubrication the tool will not work properly and parts will wear prematurely.

• Use the proper lubricant in the inline lubricator. The lubricator should be of low air now or changing air now

type and should be kept lled to the correct level. Use only recommended lubricants, specially made for pneu-

matic applications. Substitutes may harm the rubber compounds in the tool's O-rings and other rubber parts.

USER-MAINTENANCE INSTRUCTIONS

If a lter/regulator/lubricator is not installed on the air system,

air operated tools should be lubricated at least once a day or after

2 hours work with 2 to 6 drops of oil, depending on the work envi-

ronment, directly through the male tting in the tool housing. Only

a qualied technician should perform procedures not specically

explained in this manual.

1. Incorporate an in-line oiler, shut-off valve, regulator

with pressure gauge, and lter for best service, as

shown in the diagram at right. An inline shutoff valve

is an important safety device because it controls the air

supply even if the air hose is ruptured.

Note:

If an automatic oiler system is not used, add a few

drops of pneumatic tool oil to the airline connection

before operation. Add a few more drops after each hour

of continuous use.

2. Attach an air hose to the compressor's air outlet.

Connect the air hose to the air inlet of the tool.

INSTALLATION

1. Attach a standard 1/4" air connector to the tool's air inlet. Wrap the threaded portion of the air connector

with Teon tape. Tighten securely.

2. Attach a standard quick-connector to the air pressure source hose. Attach the air hose to the tool.

3. Set the air pressure regulator on the air compressor to 90 PSI.

Do not exceed the recommended pressure of 90 PSI. Excess pressure could result in damage to

the tool, to your work piece or serious injury.

4. Check the air line and its connections for air leaks. Do not use this tool until you have repaired all air leaks.

Note:

Turn off the air compressor, disconnect the air pressure hose and discharge any residual pressure before

changing accessories or making any adjustments to the tool. Failure to do so could result in severe injury or

property damage.
