10

If you switch the function knob during motor rotation, the tool can start to rotate abruptly, resulting 
in unexpected accidents. Be sure to switch the function knob when the motor is at a complete stop. 

(1) Switching to “ro hammering” 

 Turn the function knob clockwise. Align

 of the function knob and  

of the left cover as 

illustrated in 

Fig.3. 

(2) Mount the drill bit. 
(3) Pull the trigger switch after applying the drill bit tip to the drilling position

 Fig.4

(4) Pushing the rotary hammer forcibly is not necessary at all. Pushing slightly so that drill dust comes 

out gradually is sufficient. 

CAUTION: 

Although this machine is equipped with a safety clutch, if the drill bit becomes bound in concrete or 
other material, the resultant stoppage of the drill bit could cause the machine body to turn in 
reaction. Ensure that the main handle and side handle are gripped firmly during operation. 

3. When chipping and chiseling at “hammering”: 
CAUTION: 

○

 If the function knob is switched during motor rotation, the tool can start to rotate abruptly, resulting 
in unexpected accidents. Make sure to switch the function knob when the motor is at a complete stop. 

○

 If the tine chisel or flat  chisel is used at the position of “rotation hammering”, the tool can start to 
rotate, resulting in unexpected accidents. Make sure that they are used at the position of 
“hammering”. 

(1) Switching to “hammering” 

Turn the function knob counterclockwise. Align  

▲

 of the function knob and  

of the left cover as 

illustrated in 

Fig. 5.

 (2)When fixing working positions of flat  chisel such as cold chisel, etc., 

(a) Turn the function knob,Align

 of the function knob and 

of the left cover as illustrated in 

Fig. 6.

(b) Turn the flex sheath as illustrated in

 Fig. 7

 and fix the flat  chisel to the desired working direction. 

(c) Switch the selector lever to “hammering” according to the procedures mentioned in the above item 
(1) and secure the position of the tool. 

4. Install the

Orientation Staff Guage (Fig. 8) 

(1) Loosen the side handle and insert the straight portion of the orientation staff guage into the handle 

bolt hole. 

(2) Move the orientation staff guage to the specified position and rotate the grip of the side handle 

clockwise to fix the orientation staff guage. 

5. Warming up (Fig. 9) 

The grease lubrication system in this unit may require warming up in cold regions. 

Position the end of the bit so makes contact with the concrete, turn on the switch and perform the 
warming up operation. Make sure that a hitting sound is produced and then use the unit. 

CAUTION: 

When the warming up operation is performed, hold the side handle and the main body  
securely with both hands to maintain a secure grip and be careful not to twist your body by the 
jammed drill bit. 

HOW TO HANDLE A CORE BIT 

 
When a core bit is used, large diameter holes and blind holes can be drilled. In this case, use optional  
accessories for core bits (such as a dill bit and core bit shank) for more efficient operation. 

1. Mounting  

CAUTION: 

Prior to mounting a core bit, always disconnect the plug from the power supply receptacle. 

(1)

Mount the core bit on the core bit shank. 

(Fig. 10)  

Lubricate the thread of the core bit shank to facilitate disassembly.
