CAUTION:

￿Do not use the Hammer Drill in the IMPACT function if the material can be bored by rotation only. Such action will not only reduce drill efficiency, but may also damage the drill tip.

￿Operating the Hammer Drill with the change lever in mid-position may result in damage. When switching, make sure that you shift the change lever to the correct position.

HOW TO USE

CAUTION:

To prevent accidents, make sure to turn the switch off and disconnect the plug from the receptacle when the drill bits and other various parts are installed or removed. The power switch should also be turned off during a work break and after work.

1.Switch operation (Fig. 9)

￿When the trigger switch is depressed, the tool rotates. When the trigger is released, the tool stops.

￿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.

￿The rotational speed of the drill can be controlled by varying the amount that the Trigger switch is pulled. Speed is low when the trigger switch is pulled slightly and increases as the trigger switch is pulled more.

2.When using as a Drill or a Hammer Drill(1)Pressing force of the drill

You cannot drill holes more quickly even if you press the drill with a stronger force than necessary. It not only damages tip of drill bits and decreases the efficiency of operation, but also shortens the life of the drill.

(2)In case of penetrating holes

Drill bits can be broken when the material being drilled is penetrated. It is important to decrease pressing force just before penetrating.

CAUTION:

In continuous operation, conduct no-load operation for five seconds after completing a drilling job.

WARNING:

When a thick drill bit is used, your arm is subjected to larger reaction force. Be careful not to be moved by the reaction force. For this, establish a foothold, hold the unit tightly with both hands perpendicularly to the material being drilled.
