GENERAL SAFETY RULES
■For multiple hazards, read and understand the safety
instructions before installing, operating, repairing,
maintaining, changing accessories on, or working
near, the drill or tapper. Failure to do so can result in
serious bodily injury.
■Only qualified and trained operators should install,
adjust or use the drill or tapper.
■Do not modify this drill or tapper. Modifications can
reduce the effectiveness of safety measures and
increase the risks to the operator.
■Do not discard the safety instructions; give them to the
operator.
■Do not use the drill or tapper if it has been damaged.
■Tools shall be inspected periodically to verify that the
ratings and markings required by this part of ISO 11148
are legibly marked on the tool. The employer/user
shall contact the manufacturer to obtain replacement
marking labels when necessary.
PROJECTILE HAZARDS
■Be aware that the failure of the work piece, or
accessories, or even of the inserted tool itself, can
generate high-velocity projectiles.
■Always wear impact-resistant eye protection during the
operation of the drill or tapper. The grade of protection
required should be assessed for each use.
■Remove the chuck key before drilling starts.
■Ensure that the work piece is securely fixed.
ENTANGLEMENT HAZARDS
Choking, scalping and/or lacerations can occur if loose
clothing, personal jewelry, neck wear, hair or gloves are
not kept away from the tool and accessories.
OPERATING HAZARDS
■Use of the tool can expose the operator’s hands to
hazards, including cuts, abrasions and heat. Wear
suitable gloves to protect hands.
■Operators and maintenance personnel shall be
physically able to handle the bulk, weight and power
of the tool.
■Hold the tool correctly; be ready to counteract normal
or sudden movements and have both hands available.
■Maintain a balanced body position and secure footing.
■High-reaction torque can be developed in the case
of stalling, which can be caused by excessive loads
being applied to the drill bit, by the drill bit snagging on
the material being drilled into or by the drill bit breaking
through the material being drilled.
■In cases where the means to absorb the reaction
torque are requested, it is recommended to use a
suspension arm whenever possible. If that is not
possible, side handles are recommended for straight
case tools and pistol-grip tools. In any case, it is
recommended to use a means to absorb the reaction
torque above 4 Nm for straight tools and above 10 Nm
for pistol-grip tools.
■Keep hands away from the rotating chuck and drill bit.
■Release the start-and-stop device in the case of an
interruption of the energy supply.
■Use only lubricants recommended by the manufacturer.
■Personal protective safety glasses shall be
used; suitable gloves and protective clothing are
recommended.
REPETITIVE MOTIONS HAZARDS
■When using a drill or tapper to perform work-related
activities, the operator can experience discomfort in
the hands, arms, shoulders, neck or other parts of the
body.
■While using a drill or tapper, the operator should
adopt a comfortable posture while maintaining a
secure footing and avoiding awkward or off-balanced
postures. The operator should change posture during
extended tasks, which can help avoid discomfort and
fatigue.
■If the operator experiences symptoms, such as
persistent or recurring discomfort, pain, throbbing,
aching, tingling, numbness, burning sensations or
stiffness, these warning signs should not be ignored.
The operator should tell the employer and consult a
qualified health professional.
ACCESSORY HAZARDS
■Disconnect the drill or tapper from the energy
supply before fitting or changing the inserted tool or
accessory.
■Use only sizes and types of accessories and
consumables that are recommended by the drill or
tapper manufacturer; do not use other types or sizes
of accessories and consumables.
■Avoid direct contact with the inserted tool during and
after use, as it can be hot or sharp.
WORKPLACE HAZARDS
■Slips, trips and falls are major causes of workplace
injury. Be aware of slippery surfaces caused by the
use of the tool and also of trip hazards caused by the
air line or hydraulic hose.
■Proceed with care in unfamiliar surroundings. There
can be hidden hazards, such as electricity or other
utility lines.
■The drill or tapper is not intended for use in potentially
explosive atmospheres and is not insulated against
coming into contact with electric power.
■Ensure that there are no electrical cables, gas pipes,
etc., that can cause a hazard if damaged by use of
the tool.

2
DUST AND FUME HAZARDS
■Dust and fumes generated when using drills and
tappers 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.
■Risk assessment should include the dust created by
the use of the tool and the potential for disturbing
existing dust.
■Operate and maintain the drill or tapper as
recommended in these instructions, to minimize dust
and fume emissions.
■Direct the exhaust so as to minimize disturbance of
dust in a dust-filled environment.
■Where dust or fumes are created, the priority shall be
to control them at the point of emission.
■All integral features or accessories for the collection,
extraction or suppression of airborne dust and fumes
should be correctly used and maintained in accordance
with the manufacturer’s instructions.
■Select, maintain and replace the consumable/inserted
tool as recommended in the instructions handbook to
prevent an unnecessary increase in dust or fumes.
■Use respiratory protection in accordance with
employer’s instructions and as required by
occupational health and safety regulations.
NOISE HAZARDS
■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 a risk assessment and implementation
of appropriate controls for these hazards are essential.
■Appropriate controls to reduce the risk may include
actions such as damping materials to prevent
workpieces from “ringing”.
■Use hearing protection in accordance with employer’s
instructions and as required by occupational health
and safety regulations.
■Operate and maintain the drill or tapper as
recommended in the instructions handbook, to prevent
an unnecessary increase in the noise level.
■Select, maintain and replace the consumable/inserted
tool as recommended in the instructions handbook, to
prevent an unnecessary increase in noise.
■If the drill or tapper has a silencer, always ensure that
it is in place and in good working order when the drill
or tapper is operating.
VIBRATION HAZARDS
The information for use shall draw attention to vibration
hazards that have not been eliminated by design and
construction and remain as a residual vibration risk. It
shall enable employers to identify the circumstances in
which the operator is likely to be at risk from vibration
exposure. If the vibration emission value obtained using
ISO 28927-5 for drills or ISO 20643 for tappers does
not adequately represent the vibration emission in the
intended uses (and foreseeable misuses) of the machine,
additional information and/or warnings shall be supplied
to enable the risks arising from vibration to be assessed
and managed.
■Exposure to vibration can cause disabling damage to
the nerves and blood supply of the hands and arms.
■Wear warm clothing whenever working in cold
conditions and keep your hands warm and dry.
■If you experience numbness, tingling, pain or whitening
of the skin in your fingers or hands, stop using the drill
or tapper, tell your employer and consult a physician.
■Operate and maintain the drill or tapper as
recommended in the instructions handbook to prevent
an unnecessary increase in vibration levels.
■Do not allow the inserted tool to chatter on the work
piece as this is likely to cause a substantial increase
in vibration.
■Select, maintain and replace the consumable/inserted
tool as recommended in the instructions handbook to
prevent an unnecessary increase in vibration levels.
■Support the mass of the tool in a stand, tensioner or
balancer, if possible.
■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.
ADDITIONAL SAFETY INSTRUCTIONS FOR PNEU-
MATIC POWER TOOLS
■Air under pressure can cause severe injury.
■Always shut off air supply, drain hose of air pressure
and disconnect tool from air supply whenever not in
use, before changing accessories or where making
repairs.
■Never direct air at yourself or anyone else.
■Whipping hoses can cause severe injury. Always
check for damaged or loose hoses and fittings.
■Cold air shall be directed away from the hands.
■Whenever universal twist couplings (claw couplings)
are used, lock pins shall be installed and whip check
safety cables shall be used to safeguard against
possible hose-to-tool and hose-to-hose connection
failure.
■Do not exceed the maximum air pressure stated on
the tool.
■Never carry an air tool by the hose.

LUBRICATION
An automatic in-line lter-regulator-lubricator is
recommended (Fig. 7) as it increases product life and
keeps the product in sustained operation. The in-line
lubricator should be regularly checked and lled with air
tool oil.
Proper adjustment of the in-line lubricator is performed by
placing a sheet of paper next to the exhaust ports and
holding the throttle open for approximately 30 seconds.
The lubricator is properly set when a light stain of oil
collects on the paper. Excessive amounts of oil should be
avoided.
If it becomes necessary to store the product for an extended
period of time (overnight, weekend, etc.), it should receive
a generous amount of lubrication at that time. The product
should be run for approximately 30 seconds to ensure oil
has been evenly distributed throughout the product. The
product should be stored in a clean and dry environment.
It is most important that the product be properly lubricated
by keeping the air line lubricator filled and correctly
adjusted. Without proper lubrication the product will not
work properly and parts will wear prematurely.
IMPORTANT!
See Figure 7.
If a lter/regulator/lubricator is not installed on the air
system, air operated tools should be lubricated at least
once a day or after 2 hours of work with 2 - 6 drops
of oil, depending on the work environment, directly
through the male tting in the tool housing.
LOADING AND OPERATION
WARNING
Drain the air tank daily. Water in the air line will damage
the product.
■Clean the air inlet filter weekly.
■Line pressure should be increased to compensate for
unusually long air hoses (over 8 meters). The minimum
hose diameter should be 6.35 mm (1/4”) I.D. and the
fittings must have the same inside dimensions.
■The high reaction torque can be developed in the case
of stalling. Stalling can be caused by excessive loads
being applied to the drill bit, the drill bit snags on the
material being drilled into or when the drill bit breaks
through the material being drilled.
■In order to minimize the hazards due to reaction
torque, operate the product with two hands and grip
tightly.
■The unexpected tool movement or breakage of
accessories may cause injuries.
■Keep hose away from heat, oil and sharp edges. Check
hose for wear, and make sure that all connections are
secure.
■Air tools should not be used in a potentially explosive
environment.
