WORK AREA
·Keep work area clean, free of clutter and well lit. Cluttered and dark work areas can cause accidents.
·Do not use your Air Scaler where there is a risk of causing a fire or an explosion; e.g. in the
presence of flammable liquids, gasses, or dust. An Air Scaler can create sparks, which may ignite the
dust or fumes.
·Keep children and bystanders away while operating the Air Scaler. Distractions can cause you to
lose control, so visitors should remain at a safe distance from the work area.
·Be aware of all power lines, electrical circuits, water pipes and other mechanical hazards in your
work area, particularly those hazards below the work surface hidden from the operator’s view that may
be unintentionally contacted and may cause personal harm or property damage.
·Be alert of your surroundings. Using the Air Scaler in confined work areas may put you dangerously
close to cutting tools and rotating parts.
PERSONAL SAFETY
·Stay alert, watch what you are doing and use common sense when operating the Air Scaler. Do not
use the Air Scaler while you are tired or under the influence of drugs, alcohol or medication. A moment
of inattention while operating the Air Scaler may result in serious personal injury.
·Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair, clothing and
gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts. Air
vents often cover moving parts and should be avoided.
·Use safety apparel and equipment. Use ANSI-approved safety goggles or safety glasses with side
shields, or when needed, a face shield. Use as dust mask in dusty work conditions. This applies to all
persons in the work area. Also use non-skid safety shoes, hardhat, gloves, dust collection systems,
and hearing protection when appropriate.
·Do not overreach. Keep proper footing and balance at all times.
·Remove adjusting keys or wrenches before connecting to the power supply or turning on the tool. A
wrench or key that is left attached to a rotating part of the tool may result in personal injury.
PNEUMATIC TOOL USE AND CARE
·Do not force the tool. Pneumatic tools do a better and safer job when used in the manner for which
they are designed. Plan your work, and use the correct tool for the job.
·Never use a tool with a malfunctioning switch. Any power tool that cannot be controlled with the switch
is dangerous and must be repaired by an authorized service representative before using.
·Disconnect air supply from tool and place the switch in the locked or off position before making any
adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.
·Secure work with clamps or a vise instead of your hand to hold work when practical. This safety
precaution allows for proper tool operation using both hands.

4 OF 7
·Store idle tools. When tools are not is use, store them in a dry, secure place out of the reach of
children. Inspect tools for good working condition prior to storage and before re-use.
·Use only accessories that are recommended by the manufacturer for your model. Accessories that
may be suitable for one tool may create a risk of injury when used on another tool.
·Keep guards in place and in working order.
·Never leave tool running unattended.
·USE COMPRESSED AIR ONLY. Use clean, dry and regulated compressed air to power this tool.
Never use oxygen, carbon dioxide or any other bottled gas as a power source for this tool.
TOOL SET UP
Fig. 1 (Above) shows an optimal set-up that includes an inline filter, regulator and oiler. All of these
components are sold separately.
NOTE: If you are not using an automatic oiler system, before operation, add a few drops of
Pneumatic Tool Oil to the airline connection. Add a few drops more after an hour of continual use.
1. Prepare the 1/4in. air nipple to connect to the air inlet on the Air Scaler. First, wrap the
1/4in. air nipple with pipe thread seal tape (not included) before threading it into the inlet.
Connect the 3/8in. I.D. air hose (not included) to a quick-disconnect coupler (not included)
and then to the air nipple.
2. Turn on the air pressure on your compressor to 90 PSI. Do not exceed the recommended
air pressure of 90 PSI.
3. Check the air connection for leaks.
AIR SUPPLY
WARNING: Ensure the air supply is clean and does not exceed 90 PSI while operating the tool.
Too much air pressure and unclean air will shorten the product life due to excessive wear, and may
cause damage and/or personal injury.
1. Make sure that the air valve (or trigger) is in the “off” position before connecting to the air
supply.
2. An air pressure of 90 PSI is required.

3. Drain the air tank daily. Water in the airline can damage the tool.
4. Clean the air inlet filter weekly.
5. Line pressure should be increased to compensate for longer air hoses (over 26 feet or 8
meters). The hose diameter should be 3/8in. I.D.
6. Keep the hose away from heat, oil and sharp edges. Check the hose for wear and make
certain that all connections are secure.
MAINTENANCE
WARNING: Make sure the Air Scaler is disconnected from its power source before attempting any
maintenance, cleaning, or inspection.
·Maintain your Air Scaler. It is recommended that the general condition of any tool be examined
before it is used. Keep your Air Scaler in good repair by adopting a program of conscientious repair
and maintenance in accordance with the recommended procedures found in this manual. If any
abnormal vibrations or noise occurs, turn the Air Scaler off immediately and have the problem
corrected before further use. Have necessary repairs made by qualified service personnel.
·Cleaning. Use only soap and a damp cloth to clean your Air Scaler. Many household cleaners are
harmful to plastics and other insulation. Never let liquid get inside the Air Scaler.

WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains
chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
• Lead from lead-based paints
• Crystalline silica from bricks and cement and other masonry products
• Arsenic and chromium from chemically treated lumber
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your
exposure to these chemicals: work in a well-ventilated area, and work with approved safety equipment, such as
those dust masks that are specially designed to filter out microscopic particles.
