Turning the switch off
Release your hold of switch lever. Then, the
switch lever returns forward on the main
body by the spring's force, and the switch
gets turned off.
2. Pressing force of drill
You can not get holes quickly even if pressing
it by strong force more than necessary.
It not only damages the tip of drill bits and
decreases the efficiency of operation, but
also shortens the life of the drill.
3. When drilling completely through the
material
When the drill bit bores completely through
the material, careless handling often results
in a broken drill bit or damage to the drill
body itself due to the sudden movement of
the drill. Always be alert and ready to release
pushing force and hold the drill body securely
with both hands when drilling through the
material.
4. Adjusting the drilling speed
D10YB is equipped with electric control circuit
which enables non-step speed control.
To adjust the speed, turn the dial shown in
Fig. 6. When the dial is set to "1", the drilling
speed is minimum speed (500/min). When
the dial is set to "5", the drilling speed is
maximum speed (2300/min). Adjust the
drilling speed according to the material.
NOTE:
When the dial is set to "1", there can be cases
where no rotation takes place due to a power
situation, etc. In this case, raise the dial slightly
before use.
