• This tool is not insulated
against electric shock.
Be aware of buried, hidden
or other hazards in your work
environment. Do not contact
damage cords, conduits, pipes or
hoses that may contain electrical
wires, explosive gases or
harmful liquids.
Projectile Hazards
• Always wear eye protection
when operating or performing
maintenance on this tool. The
grade of protection required
should be assessed for each use
and may include impact-resistant
glasses with side shields,
goggles, or a full face shield over
those glasses.
• Ensure work pieces are secure.
Use clamps or vises to hold work
piece whenever possible.
• Failure of the work piece or
accessories can generate high-
velocity projectiles.
Noise Hazards
• Always wear hearing protection
when operating this tool.
• Exposure to high noise levels
can cause permanent, disabling
hearing loss and other problems
such as tinnitus (ringing, buzzing,
whistling or humming in the
ears). Therefore, risk assessment
and the implementation of
appropriate controls for these
hazards are essential.
Safety

6
• Appropriate controls to reduce
the risk from noise hazards may
include actions such as damping
materials to prevent work pieces
from “ringing.”
• If the tool has a silencer, always
ensure it is in place and in good
working order when the tool is
being operated.
Operating Hazards
• Operators and maintenance
personnel must be physically
able to handle the bulk, weight
and power of the tool.
• Keep body stance balanced
and rm. Do not overreach when
operating this tool. Anticipate
and be alert for sudden changes
in motion or forces during start
up and operation. The operator
should change posture during
extended tasks, which can help
avoid discomfort and fatigue.
• Use of the tool can expose
the operator’s hands to hazards,
including crushing, impacts,
cuts, abrasions and heat. Wear
suitable gloves to protect hands.
However, ensure that the gloves
do not restrict your ability to
release throttle mechanism.
• To avoid accidental starting –
ensure the tool is in the “off”
position before applying air
pressure, avoid the throttle when
carrying, and release the throttle
with loss of air.
• Do not lubricate tool with
ammable or volatile liquids
such as kerosene, diesel or jet
fuel. Use only recommended
lubricants.
• Do not carry or drag the tool by
the hose.
• Tool and/or accessories may
briey continue their motion after
throttle is released.
Accessory Hazards
• Use only sizes and types of
accessories and consumables
that are recommended by
the tool manufacturer; do not
use other types or sizes of
accessories or consumables.
Safety

7
Dust and Fume Hazards
• Wear appropriate respiratory
protection if dust or fumes are
present in the work area.
• Dust and fumes generated
when using power tools, and
existing dust disturbed by their
use can cause ill health (for
example, cancer, birth defects,
asthma and/or dermatitis,). Risk
assessment and implementation
of appropriate controls for these
hazards are essential. The priority
shall be to control them at the
source.
• Direct the exhaust so as to
minimize disturbance of dust in a
dust-lled environment.
• All integral features or
accessories for the collection,
extraction or suppression of
airborne dust or fumes should be
correctly used and maintained
in accordance with the
manufacturer’s instructions.
Prevent exposure and inhalation
of harmful dust and particles
created by power tool use.
• Some dust created by power
sanding, sawing, grinding, drilling
and other construction activities
contain chemicals known 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 dust masks that are
specially designed to lter out
microscopic particles.
Entanglement Hazards
• Entanglement of loose clothing,
personal jewelry, neckwear, hair,
gloves or other items can occur if
not kept away from the working
end of the tool. Entanglement
can result in choking, scalping,
lacerations, broken bones and/or
severed extremities.
Safety

8
Vibration Hazards
• Power tools can vibrate in
use. Exposure to vibration can
cause disabling damage to
the nerves and blood supply
of the hands and arms. If you
experience numbness, tingling,
pain or whitening of the skin in
your ngers or hands, stop using
the tool and seek advice from
a qualied health professional
before resuming use.
• Hold the tool with a light but
safe grip, taking account of the
required hand reaction forces
because the risk arising from
vibration is generally greater
where the grip force is higher.
• Wear warm clothing when
working in cold conditions and
keep your hands warm and dry.
Repetitive Motion
Hazards
• Repetitive motions or
uncomfortable positions may
be harmful to your hands, arms,
shoulders, neck or other parts
of the body. Stop using any tool
if symptoms such as persistent
or recurring discomfort, pain
throbbing, aching, tingling,
numbness, burning sensations
or stiffness occur. These warning
signs should not be ignored.
Seek advice from a qualied
health professional before
resuming use.
WARNING
Product Safety
information – When
Maintaining the Tool
• Keep the tool operating safely
through regular preventative
maintenance including regular
checks of speed and vibration.

Safety

9
• Do not remove any labels.
• Replace any damaged label.
Using The Scaler
Remember that it is always the
tool that must do the work. There
is no need for the operator to
apply extra pressure on the tool
when it is working.
Maintain the contact with the
work surface by applying enough
pressure to stop the tool from
bouncing.
Maintenance
1. To obtain maximum efciency
from the pneumatic tool, preserve
its features and avoid repeated
repairs, a routine inspection
and repair programme are
recommended at least every
1000 hours, the intervals
between the various inspections
depending on the amount of
exertion on the power tool.
2. Disassemble the tool, clean
the parts with an appropriate
solvent and check them carefully.
3. Lubricate and reassemble
the unit.
