    Feature     and Benefits
     1. Owing to shake-proof handle, the vibration is not transmitted to your hands and you will not be exhausted after a long
        time continuous operation.
     2. Very powerful in digging soft ground because of lost-hit-proof mechanism by a light re-hitting.
     3. Bit 28.6mm/31.8mm for air tools available
     4. As Motor is put laterally, the window is not closed by a worker.
     5. Plastic motor housing cover is applied so that you may not feel the machine heat even if you press it directly.

                                                  You do not feel the heat even if
                                                  contacting the surface

Anti-shaking handle
So little shaking felt in hands,
you are not exhausted.

        Mechanism against lost hitting
      Abnormal strokes are prevented by the
      mechanism. Because of so light rehitting,
      effective for digging soft ground.

Repair
1. In exchanging only Armature
   1) Take away four bolts (Hex. Socket head boltM6x20) fixing Motor housing.
   2) Remove Holder cap and Carbon brush.
   3) Hex. Nut M12 attaching Handle base in Handle side.
   4) Remove four bolts (Hex. Socket head bolt M12x55) fixing Cylinder A , separate Cylinder A from Clunk housing ,
     and detach Connecting rod and Piston cylinder attachment from Clunk shaft.
   5) Take away four bolts ( Hex. Socket head bolt M8x75) fixing Gear housing, separate Gear housing cover from Gear
     housing. At that time leave Helical gear 50 in Gear housing.
   6) Insert + Driver into a hole in the side of Helical gear 50 and fix Helical gear to set up Armature rotation. Remove
     Hex. Nut M8-13 fixing Fan 100 by Box wrench.

7) Detach Gear housing from Clunk housing. Then Fan 100 comes off from Armature.
8) Pull out Armature form Gear housing.
