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.
< DV13VSS, DV16VSS only >
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.
