ENGLISH
Keyless chuck (fig. D)
To insert a drill bit or other accessory:
Grasp the rear half of the chuck (4a) with one hand and
‹ ‹
use your other hand to rotate the front half (4) in the
counterclockwise direction, as viewed from the chuck end.
Insert the bit or other accessory fully into the chuck, and
‹ ‹
tighten securely by holding the rear half of the chuck and
rotating the front portion in the clockwise direction as
viewed from the chuck end.
Warning! Do not attempt to tighten drill bits (or any other
accessory) by gripping the front part of the chuck and turning
the tool on. Damage to the chuck and personal injury may
occur when changing accessories.
Dual range gearing (Figure F)
The dual range feature of your drill allows you to shift gears
for greater versatility. To select low speed, high torque setting
(position 1), turn tool off and permit to stop. Slide gear shifter
button (5) away from the chuck. To select the high speed, low
torque setting (position 2), turn tool off and permit to stop.
Slide gear shifter button towards the chuck.
Note: Do not change gears when tool is running. If you are
having trouble changing gears, make sure that the dual range
gear button is either completely pushed forward or completely
pushed back.
Drilling/screwdriving
Select forward or reverse rotation using the forward/
‹ ‹
reverse slider (2).
To switch the tool on, press the switch (1). The tool speed
‹ ‹
depends on how far you press the switch.
To switch the tool off, release the switch.

Hints for optimum use
Drilling
Use sharp drill bits only.
‹ ‹
Support and secure work properly, as instructed in the
‹ ‹
Safety Instructions.
Use appropriate and required safety equipment, as
‹ ‹
instructed in the Safety Instructions.
Secure and maintain work area, as instructed in the Safety
‹ ‹
Instructions.
Run the drill very slowly, using light pressure, until the hole
‹ ‹
is started enough to keep the drill bit from slipping out of it.
Apply pressure in a straight line with the bit. Use enough
‹ ‹
pressure to keep the bit biting but not so much as to stall
the motor or deflect the bit.
Hold the drill firmly with two hands to control its twisting
‹ ‹
action.
6
DO NOT CLICK THE TRIGGER OF A STALLED DRILL
‹ ‹
OFF AND ON IN AN ATTEMPT TO START IT. DAMAGE
TO THE DRILL CAN RESULT.
Minimize stalling on breakthrough by reducing pressure
‹ ‹
and slowly drilling through the last part of the hole.
Keep the motor running while pulling the bit out of a drilled
‹ ‹
hole. This will help reduce jamming.
Make sure switch turns drill on and off.
‹ ‹
Drilling in wood
Holes in wood can be made with the same twist drill bits used
for metal or with spade bits. These bits should be sharp and
should be pulled out frequently when drilling to clear chips
from the flutes.
Drilling in metal
Use a cutting lubricant when drilling metals. The exceptions
are cast iron and brass which should be drilled dry. The cutting
lubricants that work best are sulfurized cutting oil or lard oil.
Drilling in masonry
For drilling in masonry, set the collar (3) to the hammer drilling
position by aligning the symbol with the marking. Slide the
speed selector (5) towards the front of the tool (2nd gear).
Screwdriving
Always use the correct type and size of screwdriver bit.
‹ ‹
If screws are difficult to tighten, try applying a small
‹ ‹
amount of washing liquid or soap as a lubricant.
Always hold the tool and screwdriver bit in a straight line
‹ ‹
with the screw
