● Torque Setting
CAUTION:
At or Position, The clutch will not trip, so use the
auxiliary handle and pay attention to safety.
The torque force of the cup should be adjusted by
turning 22 gears to adjustthe tightening torque. The
calibration and indicating arrow should be aligned
during adjustment. The smaller the number is, the
smaller the torque will be.
● Drilling Action
CAUTION:
● Pressing excessively on the tool will not speed up
the drilling. In fact, this excessive pressure will only
serve to damage the tip of your bit, decrease the tool
performance and shorten the service life of the tool.
● There is a tremendous force exerted on the tool/bit
at the time of break- through. Hold the tool firmly and
exert care when the bit begins to break through the
work piece.
● A stuck bit can be removed simply by setting the
reversing switch to reverse rotation in order to back
out. However, the tool may back out abruptly if you
do not hold it firmly.
● Always secure small workpieces in a vise or similar
hold down device.
● Position the speed change lever to the “1” side to
drill the hole whose diameter is larger than 10mm.
Align the marketing and indicating arrows for normal
drilling operations. When drilling into a plank, use
a wood drill with a lead screw to get a good drilling
effect. To lead screw makes it easier for the bit to drill
into the workpiece. When drilling a hole in metal, to
prevent the bit from slipping, a pointed punch and
hammer can be used to make a mark on the metal
plate where the hole is intended to be drilled, and
then the bit tip can be pointed to the mark on which
the hole is drilled. When drilling on bricks, walls and
stones, aim the mark and indicator arrows, press
the drill against the operating object, and press the
switch to drill.(Fig. K)

●Tightening Bolt
CAUTION:
1.Set the tap position at the low speed.
2. Make sure that the driver bit is inserted vertically in
the bolt head, or the bolt or the bit may be damaged.
3. Please choose suitable torque according to your
operational need.
To tighten bolt, hammer the point of the driver bit at
the bolt head and force the tool properly. Switch on
the tool slowly and then speed it up gradually. Once
the clutch is closed, release the switch trigger. (Fig L)

When tightening wood screws, drill a center hole first
to make tightening action much easier and to prevent
workpiece from sliding. Please refer to the following
