PRACTICAL HANDLING PROCEDURES
1. Pressure:
Drilling will NOT be accelerated by placing heavy
pressure on the drill. Such action will only result in a
damaged drill bit, decreased drilling effi ciency and/or
shortened service life of the drill.
2. Using a large diameter drill bit:
The larger the drill bit diameter, the larger the
force on your arm. Be careful not to lose control of the
drill because of this reactive force. To maintain fi rm
control, establish a good foothold, hold the drill tightly
with both hands, and ensure that the drill is vertical to
the material being drilled.
3. When drilling completely through
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 the pushing force
when drilling through the material.

the switch is held in the ON position for continuous
operation. To turn the drill OFF, pull the trigger switch
again and release.
(2) VTV-16:
The rotational speed of the drill bit can be controlled
by varying the
Speed is low when the trigger switch is pulled slightly
and increases as the switch is pulled more. Continuous
operation may be attained by pulling the trigger switch
and depressing the stopper. To turn the switch OFF, pull
the trigger switch again to
release the trigger switch to its original position.
5. Precautions on boring
The drill may become overheated during operation;
however, it is suffi ciently operable. Do not cool the drill
bit in water or oil.
6. Caution concerning immediately after use

MAINTENANCE AND INSPECTION
1. Inspection the drill bit
Continued use of a worn and/or damaged drill bit will
result in reduced drilling effi ciency and may seriously
overload the drill motor. Inspect the drill bit often and
replace it with a new bit as necessary.
2. Inspecting the mounting screws
Regularly inspect all mounting
they are properly tightened. Should any of the screws
be loose, retighten them immediately. Fail ure to do so
could result in serious hazard.
3. Inspecting the carbon brushes (Fig. 3)
The Motor employs carbon brushes which are
consumable parts. When they become worn to or near
the
“wear limit”, it could result in motor trouble. When an
auto-stop carbon brush is equipped, the motor will stop
automatically.
At that time, replace both carbon brushes with new ones
which have the same carbon brush Numbers shown in
