(1) Clean, then smear the tool shank with the grease provided in the green tube.
(2) To attach the tool (SDS max shank), insert it
into the hole until it contacts the innermost end
of the hole as illustrated in Fig. 2.
If you continue to turn the tool with slight
pressure, you can feel a spot where there is a
hitch. At that spot, pull the grip to the direction
of an arrow mark and insert the tool all the way
until it hits the innermost end.
Releasing the grip reverts the grip and secures
the tool in place.
(3) Pull the tool to make sure it is locked
completely.
(4) To remove the tool, fully pull the grip in the
direction of the arrow and pull out the tool.
7. Regulating the number of rotations and
hammering (Fig. 3)
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 dial, depending upon the
contents of operation, such as boring holes into
fragile materials, chipping, centering, etc.
The scale '1' of the dial is designed for a
minimum speed with the number of 240
rotations per minute and 1320 times of blow
per minute. The scale '6' is designed for a
maximum speed with the number of 480
rotations per minute and 2650 times of blow
per minute.
CAUTION:
Do not adjust the dial 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
1. How to drill holes (Fig. 4)

bit tip to the drilling position.
