(2)It is unnecessary to forcibly press the rotary hammer main body. It is sufficient to slightly press the rotary hammer to an extent that shavings are freely discharged.
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.
2.How to chisel or crush (Fig. 5)
By applying the drill bit tip to the chiseling or crushing position, operate the rotary hammer by utilizing its empty weight.
Forcible pressing or thrusting is unnecessary.
3.When drilling at “rotation + hammering”:
CAUTION:
If you switch the selector lever during motor rotation, the tool can start to rotate abruptly, resulting in unexpected accidents. Be sure to switch the selector
lever when the motor is at a complete stop.
(1)Switching to “rotation + hammering”
(a)Push the button, release lock and turn the selector lever clockwise.
(b)Align ▲ of the selector lever and 
of the lever holder as illustrated in Fig. 6.
(c)Release the button to lock the selector lever.
NOTE:
Turn the selector lever (do not push the button) to check if it is completely locked and make sure that it
does not turn.
4.When chipping and chiseling at “hammering”:
CAUTION:
◯ If the selector lever is switched during motor rotation, the tool can start to rotate abruptly, resulting in unexpected accidents. Make sure to switch the selector lever when the motor is at a complete stop.
◯ If the bull point or cold 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”
(a)Push the button, release lock and turn the selector lever counterclockwise.
(b)Align ▲ of the selector lever and 
of the lever holder as illustrated in Fig. 7.
(c)Release the button to lock the selector lever.
NOTE:
Turn the selector lever (do not push the button) to check if it is completely locked and make sure that
it does not turn.
(2)When fixing working positions of tools such as cold chisel, etc.,
(a)Push the button, release lock and turn the selector lever.
Align ▲ of the selector lever and of the lever holder as illustrated in Fig. 8.
(b)Release the button to lock the selector lever.
(c)Turn the grip as illustrated in Fig. 9 and fix the tool to the desired working direction.
(d)Switch the selector lever to “hammering” according to the procedures mentioned in the above item (1) and secure the position of the tool.
5. Install the stopper (Fig. 10)
(1)Loosen the side handle and insert the straight portion of the stopper into the handle bolt hole.
(2)Move the stopper to the specified position and rotate the grip of the side handle clockwise to fix the stopper.
6.Warming up (Fig. 11)
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.
DRILLING AND DRIVING-IN OPERATIONS FOR ANCHORS
1. When a taper shank adapter is used. (Fig. 12)
(1)Install drill bit with taper shank in the taper shank adapter.
(2)Turn the power on and drill a base hole to the depth sounded by indicating groove on the drill bit.
(3)After cleaning out dust with a syringe, attach the plug to the anchor tip and drive in the anchor with a manual hammer.
(4)To remove the drill bit (taper shank), insert the cotter into the slot of the taper shank adapter and strike the head of the cotter with a manual hammer supporting on a rest. (Fig. 13)
USING DRILL CHUCK, CHUCK ADAPTER
Note that this machine can be used at “rotation only” if separately sold parts such as drill chuck and chuck adapter are attached. Use it with the selector lever positioned at “rotation + hammering”.
CAUTION:
During operation, be sure to grip the handle and the side handle firmly to prevent your body from swaying.
(1)Switching to “rotation + hammering”
For switching to “rotation + hammering”, follow the same procedures mentioned in [3. When drilling at “rotation + hammering”].
(2)Attaching chuck adapter to drill chuck (Fig. 14)
(a)Attach the chuck adapter to the drill chuck.
(b)The SDS max shank of the chuck adapter is equivalent to the drill bit. Therefore, follow the same procedure as [How to install tool] for attaching and detaching.
(3)Drilling
(a)Even if you apply
(b)A drill can snap sometimes when drilling is almost finished. It is important to relax your thrusting pressure when drilling is nearing the end.
