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 sander where there is a risk of causing a fire or an explosion; e.g.
in the presence of flammable liquids, gasses, or dust. Air sanders create sparks, which may
ignite the dust or fumes.
•Keep children and bystanders away while operating an air sander. Distractions can cause
you to lose control, so visitors should remain at a safe distance from the work area. Do not
let them handle machines, air sanders, extension cords, or air hoses.
•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 an air sander 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 an air sander.
Do not use an air sander while you are tired or under the influence of drugs, alcohol or
medication. A moment of inattention while operating air sanders 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 safety goggles or safety glasses with side shields
which comply with current national standards, 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. Do not reach over or
across running machines or air hoses.
•Remove adjusting keys or wrenches before connecting to the power supply or turning on
the air sander. A wrench or key that is left attached to a rotating part of the air sander may
result in personal injury.
PNEUMATIC AIR SANDER USE AND CARE
•Do not force the air sander. Pneumatic air sanders do a better and safer job when used in
the manner for which they are designed. Plan your work, and use the correct air sander for
the job.
•Never use an air sander with a malfunctioning switch. Any air sander that cannot be
controlled with the switch is dangerous and must be repaired by an authorized service
representative before using.
•Disconnect air supply from the air sander and place the switch in the locked or off position
before making any adjustments, changing accessories, or storing air sanders. Such
preventive safety measures reduce the risk of starting the air sander accidentally.

•Secure work with clamps or a vise instead of your hand to hold work when practical. This
safety precaution allows for proper sander operation using both hands.
•Store idle air sanders. When the air sander is not in use, store it in a dry, secure place out
of the reach of children. Inspect the air sander 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 air sander may create a risk of injury when used
on another air sander.
•Keep guards in place and in working order.
•Never leave an air sander running unattended.
•USE COMPRESSED AIR ONLY. Use clean, dry and regulated compressed air at no more
than 90 PSI to power this air sander. Never use oxygen, carbon dioxide or any other bottled
gas as a power source for this air sander.
•Use proper size and type air pressure line and fittings. The recommended air line for
this air sander is 3/8" delivering no more than 90 PSI. Recommended air inlet size is 1/4".
•Make sure the hose is free of obstructions or snags. Entangled hoses can cause loss of
balance or footing.
Note: Performance of the compressor (if powered by line voltage) may vary depending
on variations in local line voltage. Extension cord usage may also affect air sander
performance.
Additional Safety Warnings
•Repetitive motions or exposure to vibration may be harmful to your hands and arms.
•When wearing gloves to operate the Oscillating Air Sander, make sure that the gloves do
not interfere with operating the trigger. Test your gloves with the trigger before attaching the
unit to an air source.
•Never start the air sander unless you have a firm grip with both hands and you are
positioned at your workpiece or area.
•Before using the air sander, know what is directly underneath the work area or workpiece.
•The air sander can quickly penetrate material. If working directly on the ground, make sure
you are not directly above shallow cables, lines, or pipes.
•Never point the air sander or the air hose (not included) at anyone.
•Keep your finger away from the trigger until you are ready to work.

OPERATION
Set Up
Fig. 1
1. You will need to prepare a 1/4" air connector (sold separately) to connect to the Air Inlet.
First, wrap the 1/4" air connector (not included) with pipe thread seal tape before
connecting to an Air Source Hose (not included).
2. Attach air hose to the Air Inlet on the Oscillating Sander. Note: If you are not using an
automatic oiler system, before operation, add a few drops of Pneumatic Air sander Oil to
the airline connection. Add a few drops more after each hour of continual use.
3. Set the air pressure on your compressor to 90 PSI. Do not exceed the recommended air
pressure of 90 PSI.
4. Check the air connection for leaks.
MAINTENANCE
WARNING: Make sure the air sander is disconnected from its power source before
attempting any maintenance, cleaning, or inspection.
•Maintain your air sander. It is recommended that the general condition of any air sander be
examined before it is used. Keep your air sander 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 sander 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 sanders. Many household cleaners
are harmful to plastics and other insulation. Never let liquid get inside a air sander.

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.
