APPLICATIONS
○
Drilling holes in concrete
○
Drilling anchor holes
○
Crushing concrete, chipping, digging, and squaring
(by applying optional accessories)
OPERATION
1. Power source
Ensure that the power source to be utilized conforms to the power requirements specified on the
product nameplate.
2. Power switch
Ensure that the power switch is in the OFF position. If the plug is connected to a power receptacle
while the power switch is in the ON position, the power tool will start operating immediately, which
could cause a serious accident.
3. Extension cord
When the work area is removed from the power source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be kept as short as practicable.
4. How to install Drill bit
CAUTION
To prevent accidents, make sure to turn the switch off and disconnect to the plug from the receptacle.
NOTE
：
When using tools such as Tine chisel, drill bits, etc., make sure to use the genuine parts designated by
our company.
(1) To attach the drill bit (SDS-plus shank), insert it into the hole until it contacts the innermost end of
the hole as illustrated in
Fig.1.
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 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 tool in place.
(2) Pull the drill bit 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 1950 times of blow per minute. The scale ‘6’ is designed for a maximum
speed with the number of 720 rotations per minute and 4100 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.
