HOW TO USE

1. Switch operation
When the trigger is depressed, the tool rotates.
When the trigger is released, the tool stops.
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.
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. Drilling
When drilling, start the drill slowly, and gradually
increasing speed as you drill.
Always apply pressure in a straight line with the
bit. Use enough pressure to keep drilling, but do
not push hard enough to stall the motor or deflect
the bit.
To minimize stalling or breaking through the
material, reduce pressure on drill and ease the bit
through the last part of the hole.
If the drill stalls, release the trigger immediately,
remove the bit from the work and start again. Do
not click the trigger on and off in an attempt to
start a stalled drill. This can damage the drill.
The larger the drill bit diameter, the larger the
reactive force on your arm.
Be careful not to lose control of the drill because
of this reactive force.
To maintain firm control, establish a good foothold,
use side handle, hold the drill tightly with both
hands, and ensure that the drill is vertical to the
material being drilled.

MAINTENANCE AND INSPECTION

1. Inspecting the drill bits
Since use of an abraded drill bits will cause motor
malfunctioning and degraded efficiency, replace the
drill bits with a new one or resharpening without
delay when abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
to do so could result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the
power tool. Exercise due care to ensure the winding
does not become damaged and/or wet with oil or
water.
4. Inspecting the carbon brushes
For your continued safety and electrical shock
protection, carbon brush inspection and replacement
on this tool should ONLY be performed by a HITACHI
AUTHORIZED SERVICE CENTER.

marked with the letter N or coloured black.
The wire coloured brown must be connected to the
terminal marked with the letter L or coloured red.
Neither core must be connected to the earth terminal.
NOTE
This requirement is provided according to BRITISH
STANDARD 2769: 1984.
Therefore, the letter code and colour code may not be
applicable to other markets except United Kingdom.
