GENERAL SAFETY RULES
WARNING: Read and understand all instructions. Failure to follow all instructions listed
below may result in electric shock, fire and/or serious injury. The term “power tool” in all of the
warnings listed below refers to your pneumatic tool.
WARNING: The warnings, cautions, and instructions discussed in this instruction
manual cannot cover all possible conditions or situations that could occur. It must be
understood by the operator that common sense and caution are factors which cannot be built into
this product, but must be supplied by the operator.
SAVE THESE INSTRUCTIONS
WORK AREA
·Keep work area clean, free of clutter and well lit. Cluttered and dark work areas can cause
accidents.
·Do not use your tool where there is a risk of causing a fire or an explosion; e.g. in the
presence of flammable liquids, gasses, or dust. Power tools create sparks, which may ignite the
dust or fumes.

Page: 3 of 8
·Keep children, bystanders and pets away while operating a power tool. 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 power tools 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 a power tool. Do
not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A
moment of inattention while operating power tools 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.
·Avoid accidental starting. Do not carry the power tool with your finger on the switch. Ensure
the switch is in the off position before plugging tool into power outlet. In the event of a power
failure, while a tool is being used, turn the switch off to prevent surprise starting when power is
restored.
·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. 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.
·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.
·Use proper size and type extension cord. If an extension cord is required for the air
compressor, it must be of the proper size and type to supply the correct current to the tool
without heating up. Otherwise, the extension cord could melt and catch fire, or cause electrical
damage to the tool. Check your compressor’s manual for the appropriate size cord.

·Keep guards in place and in working order.
·Never leave tool running unattended.
·Compressed air only. Only use clean, dry and regulated compressed air at no more than 90
PSI to power this tool. Never use oxygen, carbon dioxide or any other bottled gas as a power
source for this tool.
·Use proper size and type air pressure line and fittings.
·Use air hoses rated for safe operation of the tool.
·Make sure the hose is free of obstructions or snags. Entangled hoses can cause loss of
balance or footing.
·For your safety, maintenance should be performed regularly by a qualified technician.
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 tool performance.
Additional Safety Warnings
·Repetitive motions or exposure to vibration may be harmful to your hands and arms.
·When wearing gloves to operate the Air Needle Scaler, 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 tool unless you have a firm grip with both hands and you are positioned at your
workpiece or area.
·Before using the Air Needle Scaler, know what is directly underneath the work area or
workpiece.
·The Air Needle Scaler 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 tool 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
·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 a
Air Source Hose (not included).
·Attach air hose to the Air Inlet on the Air Needle Scaler. 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 each hour of continual use.

·Set the air pressure on your compressor to 90 PSI. Do not exceed the recommended air
pressure of 90 PSI.
·Check the air connection for leaks.
·Turn off the compressor and disconnect the air source hose in preparation to load bits into
the Air Needle Scaler.
·Take out the needle scaler from the box (See Fig. 2), screw it into the cylinder (See Fig. 3),
tighten it (See Fig. 4) and start the trigger.
Fig. 2 Fig. 3 Fig. 4
·Gently squeeze the trigger and move slowly along the workpiece. Do not push down on the
scaler; let it do the work. If it does not do the intended job to satisfaction, examine your scaler
to see if it is worn or dull.
·When you are finished, turn off the air supply and then hold the Air Needle Scaler a safe
distance away from yourself and others and squeeze the trigger to bleed off the remaining air.
Then, disconnect the air hose.
MAINTENANCE
WARNING: Make sure this tool is disconnected from its power source before attempting
any maintenance, cleaning, or inspection.
·Maintain your tools. It is recommended that the general condition of any tool be examined
before it is used. Keep your tools 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 tool 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 tools. Many household cleaners are
harmful to plastics and other insulation. Never let liquid get inside a tool.

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, and
• 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.
