WARNING: To reduce the risk of injury, turn unit off and
disconnect tool from power source before installing and
removing accessories, before making any adjustments or
removing/installing attachments or accessories.
WARNING:
Be aware of the location of pipework and wiring.
WARNING:
Apply only a gentle pressure to the tool. Excessive
force does not speed up drilling but decreases tool performance
and may shorten tool life.
PrIor to oPeratIon
• Insert the appropriate bit.
• Mark the spot where the hole is to be drilled.
Switching on and off (fig. 1)
To run the tool, press the variable speed switch (E). The pressure
exerted on the variable speed switch determines the tool speed.
if necessary, press the lock-on button (F) for continuous operation
and release the switch.
The lock-on button works only in full speed, forward rotation.
To stop the tool, release the switch.
To stop the tool in continuous operation, press the switch briefly
and release it. Always switch off the tool when work is finished and
before unplugging.
reversible variable Speed Electric
control (fig. 1)
The pressure that is put on the trigger sets the tool speed,
which makes it easier to operate when it is used as an electric
screwdriver.
Use low speed to begin the hole and then accelerate the drill by
putting more pressure on the trigger.
Keep the motor on while pulling the drill out of the hole as this
prevents it from getting stuck.
To select the rotation direction, check the direction of the arrows
near the reverse slider (D), which is located just above the trigger.
Wait for the motor to stop before reversing the rotation direction.
Screwdriving
Select forward or reverse rotation.
Percussion Drilling (fig. 1)
1. Select the percussion mode.
2. Press the switch (E).
rotary Drilling
1. Select the rotary drilling mode.
2. Proceed as described for percussion drilling.
Drilling
1. Use sharp drill bits only. For WOOD, begin with low speed and
use twist drill bits, spade bits, power auger bits or hole saws.
For METAL, begin with low speed and use steel twist drill bits
or hole saws. Use a cutting lubricant when drilling metals. The
exceptions are cast iron and brass which should be drilled
dry.
note:
Large [5/16" (8 mm) to 1/2" (13 mm)] holes in steel can
be made easier if a pilot hole [5/32" (4 mm) to 3/16" (5 mm)] is
drilled first.
2. Always apply pressure in a straight line with the bit. Use enough
pressure to keep drill biting, but do not push hard enough to
stall the motor or deflect the bit.
3. Hold tool firmly with both hands to control the twisting action of
the drill.
WARNING
:
Drill may stall if overloaded causing a sudden twist.
Always expect the stall. Grip the drill firmly with both hands to
control the twisting action and avoid injury.
