vibration.
WARNING! Whipping hoses can cause severe
injury. ALWAYS check for and replace
damaged or loose hoses and ttings.
• Ensure that the product is compatible with the air
supply before use.
• Ensure all connections are securely tightened.
• Where universal twist couplings (claw couplings) are
used, lock pins must be installed and whip check
safety cables must be used to safeguard against
possible hose-to-tool or hose-to-hose failure.
• DO NOT exceed the maximum stated air pressure.
• The use of an inline water separator, lubricator and
pressure regulator should be used to control the
pressure of the air being supplied to the tool.
• DO NOT obstruct the ability of the trigger to release
once depressed.
• NEVER carry the tool by the air line.
4.3 Additional Safety Instructions for Air
Needle Scalers
WARNING! Risk of injury
to persons.
− Keep hands away from the needles.

using this needle scaler.
• Where dust or fumes are created, the priority should
be to control them at the point of emission.
• Disconnect the tool from the energy supply before
changing the inserted tool or accessory.
• Failure of the workpiece, accessories or even of the
inserted tool itself can generate high-velocity
projectiles.
• ALWAYS wear impact-resistant eye protection during
the operation of the needle scaler. The grade of
protection required should be assessed for each use.
• For overhead work, wear a safety helmet. The risk to
others should also be assessed at this time.
• Ensure that the workpiece is securely xed.
• NEVER operate a tool unless the inserted tool is
retained with a proper retainer.

permanent hearing loss and other problems.
Perform a risk assessment and implement any
appropriate controls for identied hazards before
performing any operation.
− Use appropriate hearing protection in accordance
with local occupational health and safety
regulations.
− Operate and maintain the tool appropriately to
prevent unnecessary increase in noise emissions.
• Vibration Hazards
− Exposure to vibration can cause disabling damage
to the nerves and blood supply of the hands and
arms.
− Wear warm clothing when working in cold
conditions and keep your hands warm and dry.
− If you experience numbness, tingling, pain or
whitening of the skin in your ngers or hands,
stop using the tool and consult a qualied health
professional.
− Operate and maintain the tool appropriately to
prevent unnecessary increase in vibration
emissions.
− The risks from vibration hazards are increased
when grip force on the tool is higher. − Hold the
tool with a light but safe grip, keeping in mind that
your grip may need to be altered to react to
unexpected forces.

• This air tool operates at a max. pressure of 6.2bar
(90psi).
• ISO grade 22–32 (SAE grade 5W–15W) monograde oil
should be used in this air tool.
• During use, the oil must be constantly supplied to the
equipment to ensure complete lubrication and
optimum performance.
• The compressed air system must be controlled by a
combination pressure regulator, in-line lubricator and
moisture lter. This will ensure a constant supply of
dry air at all times, provided it is properly maintained.
Important: ALWAYS check the machine operating
pressure before use.
• Water in the compressor tank may cause
considerable corrosion to air tools; the compressor
should be drained daily to avoid excessive water in
the air supply. Dirty or wet air can signicantly
shorten the lifespan of the product.
• When using an air tool with a hose over 25ft long,
Draper Tools recommends increasing the bore of the
hose to the next largest available size (i.e. increase
3⁄8" to 1⁄2"). This will ensure adequate pressure and
volume of air to power the tool.
