9.4.1 Switch lock (Fig 4)
The switch trigger can be locked in the center position.
This helps to reduce the possibility of accidental starting when not in use. To lock the switch
trigger, place the direction of rotation selector in the center position.
9.4.2 Direction of rotation (Fig 5)
Direction of rotation is controlled by the direction of rotation selector located above the switch
trigger.
9.4.2.1 Clockwise rotation:
Right : To select forward rotation, release the on/off switch and push the forward/reverse lever
to the left side of the tool.
9.4.2.2 Anticlockwise rotation:
Left : To select reverse rotation, push the lever to the right side of the tool.
9.4.3 Variable speed
This tool has a variable speed switch that delivers higher speed and torque with increased
trigger pressure.
Speed is controlled by the amount of switch trigger depression.
9.5 Adjusting the torque
The torque is adjusted by rotating the torque setting ring; the torque is greater when the torque
setting is set on a higher position. The torque is less when the torque setting ring is set on a
low position“1”denote lowest and “23” denote highest.
Torque is set by means of a torque setting according to different screw and different material,
you can adjust suitable torque, if the screw is long and material is hard, you can adjust the
bigger setting.
9.6 Torque adjustment ring
▪ Turn the torque adjustment ring and let the pointer align to the impact mode that selects
the impact mode of action.
▪ Turn the torque adjustment ring and let the pointer align to the drill mode that selects
the drill mode of action.
9.7 Speed selector (Fig 6)
NOTE： Mark “1”is Low speed position, mark “2” is High speed
position that moulding onto the button of two speed selector .
The drill has a two-speed gear train designed for drilling at 1 (LOW) or 2 (HIGH) speed. A gear
selector is located on top of the drill to select either low or high speed. When you push the
button forward and select low speed range, the speed will decrease but will provide more
power and torque. When using drill in the high speed range. Speed will increase but will
provide less power and torque. Use low speed for high power and torque application and high
speed for fast drilling applications.
Important: NEVER adjust this two speed selector whilst the drill is running.
Always let it come to a complete stop first.
