At that spot, pull the flex sheath to the direction of an arrow mark and insert the drill bit all the way
until it hits the innermost end.
Releasing the flex sheath reverts the flex sheath and secures the drill bit in place.
(2) Pull the tool to make sure it is locked completely.
(3) To remove the drill bit, fully pull the flex sheath in the direction of the arrow and pull out the drill
bit.
5. Regulating the number of rotations and hammering (Fig. 2)
This Rotary Hammer is equipped with a built-in electronic control circuit that can adjust and regulate
the number of rotations and times of hammering. This Rotary Hammer can be used by adjusting the
speed adjuster knob, depending upon the contents of operation, such as boring holes into fragile
materials, chipping, centering, etc.
The scale’1’ of the speed adjuster knob is designed for a minimum speed with the number of 300
rotations per minute and 2000 times of blow per minute. The scale ‘6’ is designed for a maximum
speed with the number of 720 rotations per minute and 4200 times of blow per minute.
CAUTION:
Do not adjust the speed adjuster knob during operation. Doing so can result in injury because the
Rotary Hammer must be held by only one hand, disabling the steady control of the Rotary Hammer.
HOW TO USE THE ROTARY HAMMER
CAUTION:
To prevent accidents, make sure to turn the switch off and disconnect the plug from the receptacle
