Selecting the action mode
This tool employs an action mode changing knob. Select one of the three modes suitable for your work needs by using this knob.
For rotation only, turn the knob so that the arrow on the knob
points toward the 
mark on the tool body.
For hammering only, turn the knob so that the arrow on the
knob points toward the 
mark on the tool body.
For rotation with hammering, turn the knob so that the arrow
on the knob points toward the | mark on the tool body. |
CAUTION:
•Always set the knob correctly to your desired mode mark. If you operate the tool with the knob positioned halfway between the mode marks, the tool may be damaged.
NOTE:
•When it is hard to turn the knob, pull the switch trigger halfway for running at low speed and turn the knob.
ASSEMBLY
Torque limiter
The torque limiter will actuate when a certain torque level is reached. The motor will disengage from the output shaft. When this happens, the bit will stop turning.
CAUTION:
•As soon as the torque limiter actuates, switch off the tool immediately. This will help prevent premature wear of the tool.
•Hole saws, core bits, diamond core bits, etc. cannot be used with this tool. They tend to pinch or catch easily in the hole. This will cause the torque limiter to actuate too frequently.
CAUTION:
•Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.
