SAFETY GUIDELINES
• Keep work area clean. Never operate the product near flammable substances like gasoline, naphtha,
cleaning solvents, etc. Work in a clean, well-ventilated area free of combustible materials. Cluttered
areas invite injuries.
• Ensure that there are no electrical cables, gas pipes, etc., which can cause a hazard if damaged
by use of the tool.
• Never connect to an air source that is capable of exceeding 200 PSI. Always verify prior to
using this tool that the air source has been adjusted to the rated air pressure range.
• Do not exceed maximum working pressure of 90 PSI for the tool. Over pressurizing the
tool may cause bursting, abnormal operation, breakage of the tool or serious injury to persons. Use
compressed air regulated to a maximum pressure at or below the rated pressure of any attachments to
this product.
• Never use oxygen, carbon dioxide, combustible gases or any other bottled gases as an air
source for the tool. Such gases are capable of explosion and serious injury to persons.
• Disconnect the tool from the air source before making any adjustments, changing
accessories, or storing the tool. Such preventative safety measures reduce the risk of starting the
tool unintentionally.
• Observe work area conditions. Don’t expose to rain. Keep work area well lighted.
• Keep children away. Children must never be allowed in the work area. Do not let them handle
machines, tools, extension cords, or air hoses. Keep visitors a safe distance from the work area.
• Store idle equipment. When not in use, the tool must be stored in a dry location to inhibit rust.
Always lock up tools and keep out of reach of children.
• Dress properly. Do not wear loose clothing or jewellery as they can be caught in moving parts.
Protective, electrically non-conductive clothes and non-skid footwear are recommended when working.
Wear restrictive hair covering to contain long hair.
• Do not overreach. Keep proper footing and balance at all times, which enables better control of the
tool in unexpected situations.
• Protect your eyes by wearing safety glasses or a face shield when using this tool. Ear protectors
should also be worn.
• Maintain the product with care. Inspect hose periodically and, if damaged, have it repaired by an
authorized technician.
• Install an in-line shutoff valve to allow immediate control over the air supply in an emergency, even
if a hose is ruptured.
• 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. There are certain applications for which this product was designed. Do not modify
this tool and do not use this tool for a purpose for which it was not intended.

SAFETY GUIDELINES
• Do not apply excessive force of any kind to the tool. Let the tool perform the work at the rate for
which it was designed.
• Stay alert. Watch what you are doing. Use common sense. Do not operate any tool when you are
tired.
• Do not operate tool under the influence of alcohol or drugs. Read warning labels on
prescriptions to determine if your judgment or reflexes are impaired while taking drugs. If there is any
doubt, do not operate the tool.
• Check for damaged parts. Before using any tool, any part that appears damaged should be
carefully checked to determine that it will operate properly and perform its intended function. Check
for alignment and binding of moving parts, any broken parts, and any other condition that may affect
proper operation. Any part that is damaged should be properly repaired or replaced by a qualified
technician.
• Keep working parts of the tool away from hands and body during operation.
• Replacement parts and accessories. When servicing, only use identical replacement parts. Use of
any other parts will void the warranty. Only use accessories intended for use with this tool.
• Use proper size and type of air connection hose. If an air connection hose is required, it must
be of the proper size and type to supply the correct current to the tool without heating up. Check your
compressor manual for extension cord information.
• Keep the air supply hose away from heat, oil and sharp edges. Check hose for wear before
each use.
• Do not carry the tool by air hose.
• Do not remove any labels on the tool. Replace if they become obscured or damaged.
• Maintenance. For your safety, maintenance should be performed regularly by a qualified technician.
• CA PROP 65: This product contains chemicals known to the state of California to cause cancer and
birth defects or other reproductive harm. Wash hands after handling.
AIR SUPPLY
AIR SUPPLY
Please refer to the typical air system layout recommended below.
1. Use only clean, dry, regulated compressed air as the power source.
2. Make sure that the air compressor being used for the tool operation supplies the correct output (CFM).
3. Have the tool in "off" position when connecting the tool to the air supply.
4. Use normal 90 PSI working pressure for the tool. High pressure and unclean air will shorten the tool life
due to the faster wear and also may create a safety hazard.
5. Drain water from the air compressor tank daily, as well as any condensation in the air lines. Water in the
air line may enter the tool and cause damage to the tool mechanisms at operation.
6. Clean the tool air inlet screen filter for blockage weekly. Clean if necessary.
7. Usually a 3/8" (9.5 mm) inner diameter air hose is recommended for air supply and airflow to get the
optimum performance of tool.
8. A long air hose (usually over 25' (8 m)) may cause up to 15 PSI drop in pressure, so you need to set the
output pressure of the air compressor higher to maintain the required working pressure at the tool.
9. Use proper hoses and fittings. We do not suggest connecting quick change couplings directly to the tool
since they may cause failure due to tool vibration at operation. Instead, add a lead hose and connect
coupling between air supply and hose whip.
10. Check hoses for wear before each use. Make certain that all connections are secure.

MAINTENANCE
1. Always operate the tool with care by following the instructions in the manual.
2. Always disconnect air connection hose and air supply when tool is not in use.
3. Check air hose for frays and tears.
4. If the tool fails, have it repaired or replaced by an authorized technician.
5. In the event that it becomes necessary to store the tool for an extended period of time, it should receive a
generous amount of lubrication at that time. The tool should be lubricated through the air inlet and should
run for approximately 30 seconds to ensure that the lubricating oil has been evenly distributed throughout
the tool.
6. When you are not using the product for a long time, wipe it clean with a dry cloth and store it in a dry and
safe place out of reach of children.

PARTS LIST
TROUBLESHOOTING
Problem Possible Cause Corrective Action
Tool runs
slowly or will
not operate
1. Grit or gum in tool.
2. No oil in tool.
3. Low air pressure.
4. Air hose leaks.
5. Pressure drops.
6. Worn rotor blade.
7. Moisture blowing
out of tool exhaust.
1. Flush the tool with air-tool oil or gum solvent.
2. Lubricate the tool according to the lubrication
instructions in this manual.
3. a. Adjust the regulator on the tool to maximum
setting.
b. Adjust the compressor regulator to tool maximum
of 90 PSI/6.3 BAR.
4. Tighten and seal hose fittings if leaks are found. Use
sealing tape.
5. a. Be sure the hose is the proper size. Long hose or
tools using large volumes of air may require a hose
with an I.D. of 1/2" (12.5 mm) or larger depending
on the total length of the hoses.
b. Do not use a multiple number of hoses connected
together with quick-connect fittings. This causes
additional pressure drops and reduces the tool
power. Directly connect the hoses together.
6. Replace rotor blade.
7. Water in tank: drain tank. (See air compressor
manual.) Oil tool and run until no water is evident.
Oil tool again and run 1-2 seconds.
Abnormal
vibration and/or
excessive heat
develops in
the tool.
Improper lubrication. Follow proper lubrication procedures in
this manual.
WARNING!
Follow all safety precautions whenever diagnosing or servicing the engraving pen. Disconnect air supply
before service.
