OPERATION FOR CORDLESS DRILL
If you tighten the screw for a time longer than shown in
the figures, the screw or the point of the driver bit may be
overstressed, stripped, damaged, etc. Before starting your
job, always perform a test operation to determine the
proper fastening time for your screw.
The fastening torque is affected by a wide variety of factors
including the following. After fastening, always check the
torque with a torque wrench.
1. When the battery pack is discharged almost
completely, voltage will drop and the fastening torque
will be reduced.
2. Failure to use the correct size driver bit or socket bit
will cause a reduction in the fastening torque.
3. Even though the torque coefficient and the class of
bolt are the same, the proper fastening torque will
differ according to the diameter of bolt. Even though
the diameters of bolts are the same, the proper
fastening torque will differ according to the torque
coefficient, the class of bolt and the bolt length.
4. The torque may be affected by the material to fasten,
or the position in which the tool is held.
5. Operating the tool at low speed will cause a reduction
in the fastening torque.
ENGLISH
Starting Operation
Switching on:
To start the tool squeeze on the On/Off switch(4) and
then keep it pressed down.
Switching off:
To stop the tool, release the On/Off switch (4).
Reversing the Rotational Direction
The direction of rotation can be changed with the
forward/reverse lever (4). This is located above the
variable speed trigger (3)
1. To select the forward drilling position, push the
forward/reverse lever (4) hard left.
forward/reverse lever (4) hard right.
2. To select the reverse drilling position push the
by pushing the forward/reverse lever (4) into the
middle of both forward and reverse positions.
3. The variable speed trigger (3) can be locked off
Setting the Torque
The fastening torque can be adjusted in 24+1
settings by turning the adjusting ring so that its
graduations are aligned with the pointer on the
tool body.
The fastening torque is minimum when the number
1 is aligned with the pointer and maximum when
symbol ‘ ’ is aligned with the pointer. The clutch
will slip at various torque levels when set at the
number 1 to 24+1.Before actual operation, drive
a trial screw into your material or a piece of
duplicate material to determine which torque is
required for a particular application.
Gear Selection, Mechanical
Actuate the gear selector (9) only when the
tool is at a standstill.
Two speed ranges can be used with the gear
selector (9).
Gear 1:
Low speed range (0-400 RPM); for screwdriving
or working with large drilling diameter.
Gear 2:
High speed range (0-1200 RPM); for working
with small drilling diameter.
If the gear selector (9) cannot be fully engaged,
lightly rotate the driver spindle with the drill bit by
twisting the drill chuck.
Adjusting the Speed
The speed of the switched on power tool can be
variably adjusted, depending on how far the On/Off
switch (3) is pressed.
Light pressure on the On/Off switch (3) results in
a low rotational speed. Further pressure on the
switch results in increased speed.
