HOW TO USE THE DRILL
1. Pressing force of drill
You can not get holes quickly even if pressing it by strong force more than necessary.
If not only damages the tip of drill bits and decreases the efficency of operation, but also
shortens the life of the drill.
2. In case of penetrating holes
It is subject to break the drill bits when penetrating. It is important to decrease pressing
force when penetrating.
3. Operation of switch
(1) Trigger switch
⅜ When the trigger switch is depressed, the tool rotates. When the trigger is released,
the tool stops.
⅜ Pulling the trigger and pushing the stopper, it keeps the switched-on condition
which is convenient for continuous running. When switching off, the stopper can be
disconnected by pulling the trigger again.
(2) Reversing switch
This drill can rotate both clockwise (for drilling) and counterclockwise (for releasing the
drill bit) by operating the reversing switch.
CAUTION
Never change the direction of bit rotation while operating. Turn the power switch OFF
before changing the direction of bit rotation; otherwise, burning of the motor will result.
MAINTENANCE AND INSPECTION
WARNING: Be sure to switch power OFF and disconnect the plug from the
receptacle during maintenance and inspection.
1. Inspecting the dril bits
Since use of an abraded drill bit will cause motor malfunctionning and degraded
efficiency, replace the drill bit with a new one or resharpening without delay when
abrasion is noted.
10. Installing the side handle
The side handle screws into the housing and two
sides of the gear cover. For safe operation, use of
the side handle is necessary. Especially in heavy
duty drilling, use handle joint and side handle.
11. Installing the depth stopper (optional ac-
cessory)
The depth stopper which is useful for adjusting the
drilling depth is available. Install the depth stopper
to the gear cover using the side handle or set screw.
