8. CHUCK ADJUSTMENT
To open the chuck jaws, rotate the front section of the
chuck counter-clockwise. Once the chuck jaws open to
the desired position, insert the bit, then rotate the chuck
clockwise until the bit fits the chuck. Ensure that the drill/
driver bit is in the centre of the chuck jaws. Aligning the
teeth, insert the chuck key into the hole at the front sec-
tion of the chuck and turn to tighten. Finally, using the
chuck key, firmly rotate the two separate chuck sections
in opposite directions until your drill/driver bit is secured
firmly in the chuck.To remove bit, loosen the chuck jaws
with the chuck key and repeat the aforementioned steps
(See Fig 6).
Warning: Before installing accessory, re-
move plug from power supply. Do not at-
tempt 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 result.
9. ADJUSTABLE DEPTH GAUGE
Fit the drill bit or driver bit into the chuck. Loosen the
depth gauge by rotating the handle counter-clockwise.
Slide the depth gauge until the distance between the
depth gauge end and the drill/driver bit end is equal to
the depth of hole/screw you wish to make. Then clamp
the depth gauge by rotating the handle clockwise.
WORKING HINTS FOR YOUR
DRILL
If your power tool becomes too hot, set the speed to
maximum and run no load for 2-3 minutes to cool the
motor.
Tungsten carbide drill bits should always be used for
concrete and masonry.
When drilling in metal, only use HSS,Titanium or Cobalt
drill bits that are in good condition.
Always use a magnetic bit holder when using short
screwdriver bits.
Where possible use a pilot hole before drilling a large
diameter hole in metal material.
MAINTAIN TOOLS WITH CARE
Keep tools sharp and clean for better and safer perfor-
mance. Follow instructions for lubricating and changing
accessories. Inspect tool cords periodically and if dam-
aged, have repaired by authorized service facility.
