normal operating speed.
Important!
At the start of drilling
,
select a lower speed to avoid the bit
slipping away from the desired holes location. If the drill-hole is deep, the drill-bit
may become jammed in the hole. In this event
,
a high torque could damage the
drill bit or the drill. If the bit becomes jammed, hold the tool firmly and
immediately release the On/Off trigger. Switch to counterclockwise rotation, and
use a low rotation speed to remove the jammed drill bit more easily.
4. Drilling in plastic
For drilling in plastic
,
use a steel drill and follow the same instructions as for
drilling in wood.
5. Hammer drilling
For drilling in walls, stone, masonry etc. use a masonry-bit. Do not put too much
pressure on the tool; too much force will cause slower drilling speeds
overheating, and a lower drilling rate. Follow the same instructions as for drilling
in metal. When drilling deep holes, if the hammer speed starts to drop off. pull
the bit partially out of the hole with the tool still running to help clear debris from
the hole.
NOTE:
A smooth, even flow of dust from the hole indicates proper drilling rate.
WARNING:
Always wear ANSI Z87.1 approved eye protection when performing this.
6. Using the drill as a screw-driver
Before using the tool
,
check whether the screw-bit is inserted correctly. Avoid
over-tightening screws, otherwise the screw head may be damaged or stripping
of the threads may occur.
7. Screw insertion
Set the rotation direction of the drill to the clockwise direction. Insert the
screw-bit into the slot in the head of the screw. Hold the screw bit perpendicular
to the head of the screw, otherwise the screw or the screw head may be
damaged. Press the screw bit against the screw with a constant pressure while
driving in the screw.
When the screw is completely screwed in, hold the tool firmly and release the
On/Off trigger, otherwise the screw or the screw head may be damaged. If the
On/Off trigger is not released immediately
,
a high torque could also damage the
drill bit or the drill.
8. Screw removal
Set the rotation direction of the drill to the counterclockwise direction. Insert the
screw-bit into the slot in the head of the screw. Hold the screw-bit perpendicular
to the head of the screw, otherwise the screw or the screw head may be
