or driving at low (mark is 1) or high (mark is 2) speeds. A
slide switch (3) is located on top of the drill to select either
low or high speed. When using the drill in the low speed
range, the speed will decrease and the drill will have
greater power and torque. When using the drill in the high
speed range, the speed will increase and the drill will have
less power and torque.
WARNING:
To prevent gear damage, always allow
the chuck to come to a complete stop before
changing the direction of rotation or the two-speed gear
train.

chuck. Insert suitable screwdriver bit(or drill bit) between
the chuck jaws and rotate the front section in the opposite
direction. Ensure the bit is in the centre of the chuck jaws.
Finally, firmly rotate the front chuck section in the opposite
directions. Your bit is now clamped in the chuck.
