Safety instructions when using long drill bits:
Never operate at higher speed than the maximum speed rating of the drill bit . At higher
speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece,
resulting in personal injury.
Always start drilling at low speed and with the bit tip in contact with the workpiece .
At higher speeds, the bit is likely to bend if allowed to rotate freely without contacting the
workpiece, resulting in personal injury.
Apply pressure only in direct line with the bit and do not apply excessive pressure . Bits
can bend causing breakage or loss of control, resulting in personal injury.
ADDITIONAL SAFETY WARNINGS
Use clamps or another practical way to secure and support the workpiece to a stable
platform . Holding the work by hand or against your body leaves it unstable and may lead to
loss of control.
Do not drill, fasten or break into existing walls or other blind areas where electrical
wiring may exist . If this situation is unavoidable, disconnect all fuses or circuit breakers
feeding this worksite.
Always wear safety goggles or eye protection when using this tool . Use a dust mask or
respirator for applications which generate dust .
Use thick cushioned gloves and limit the exposure time by taking frequent rest periods.
Vibration caused by hammer-drill action may be harmful to your hands and arms.
Secure the material being drilled . Never hold it in your hand or across legs . Unstable
support can cause the drill bit to bind causing loss of control and injury.
Never leave the trigger locked "ON" . Before plugging the tool in, check that the
trigger lock is "OFF" . Accidental start-ups could cause injury.
Position the cord clear of rotating bit . Do not wrap the cord around your arm or wrist .
If you lose control and have the cord wrapped around your arm or wrist it may entrap you and
cause injury.
Position yourself to avoid being caught between the tool or side handle and walls or
posts . Should the bit become bound or jammed in the work, the reaction torque of the tool
could crush your hand or leg.
If the bit becomes bound in the workpiece, release the trigger immediately, reverse the
direction of rotation and slowly squeeze the trigger to back out the bit. Be ready for a
strong reaction torque. The drill body will tend to twist in the opposite direction as the drill bit is
rotating.
Do not grasp the tool or place your hands too close to the spinning chuck or drill bit .
Your hand may be lacerated.
Do not use the switch "Lock-On" feature in situations where drill bit binding is likely . (For
example: just before the bit is ready to break through the material, anytime when using
a "Hole Saw", auger bits . . . . . . . . etc .) When the bit binds, the drill's body will twist or kick-back
in opposite direction and the release of the trigger "Lock-On" may be difficult.
Be aware of the location and setting of the switch "Lock-On" button . If the switch is
locked "ON" during the use, be ready for emergency situations to switch it "OFF", by first
pulling the trigger then immediately releasing it without pressing the "Lock-On" button.
When installing a drill bit, insert the shank of the bit well within the jaws of the chuck . If
the bit is not inserted deep enough, the grip of the jaws over the bit is reduced and the loss of
control is increased.
Do not use dull or damaged bits and accessories . Dull or damaged bits have a greater
tendency to bind in the workpiece.
