USING DRILL CHUCK, CHUCK ADAPTOR

Note that this machine can be used at “rotation only” if separately sold parts such as drill chuck and chuck adaptor are attached. Use it with the selector lever positioned at “rotation + hammering”.

WARNING:

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”] in Page 8.

(2)Attaching chuck adaptor to drill chuck (Fig. 12)

(a)Attach the chuck adaptor to the drill chuck.

(b)The SDS max shank of the chuck adaptor is equivalent to the drill bit. Therefore, follow the same procedure as [6. How to install tool] in Page 7 for attaching and detaching.

(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.

HOW TO USE THE CORE BIT

When boring penetrating large hole use the core bit. At that time use with the center pin and the core bit shank provided as optional accessories.

1.Mounting

CAUTION:

Be sure to turn power OFF and disconnect the plug from the receptacle.

(1)Mount the core bit to the core bit shank. (Fig. 13) Lubricate the thread of the core bit shank to facilitate disassembly.

(3)Drilling

(a)Even if you apply more-than-required pressure to the machine body, drilling can never be performed as quickly as you expect. Applying more force or pressure to the machine body than what is needed, on the contrary, damages the drill tip, resulting in the declined working efficiency and shortened life of this machine.

(3)Insert the center pin into the guide plate until it stops.

(4)Engage the guide plate with the core bit, and turn the guide plate to left or right so that it does not fall even if it faces downward. (Fig. 15)
