7. Installing the side handle (Optional accessory)
A Side handle can be installed on either side of
the tool for right or left handed use.
To install the side handle, thread it into the socket
on the desired side of the gear cover and tighten
it securely. (Fig. 6)
8. Attaching the hook. (Optional accessory)
For hook (side-attaching)
Fix the hook firmly on the desired side of the gear
cover using M10 bolt which is supplied with hook.
For hook (A) (top-attaching)
To attach the hook (A), it is necessary to disassemble
the handle portion which covered the tool's electrical
system. For your continued safety and electrical
shock protection, installing the hook (A) on this drill
should ONLY be performed by a HITACHI
AUTHORIZED SERVICE CENTER.
CAUTION:
When the power tool is used with a hook fixed to
it, pay attention to the following points:
Before hanging the main unit from the waist belt,
make sure that the drill has come to a complete
stop.
While it is suspended from the waist belt, the power
plug must be disconnected from the power source.
Do not walk about with the power tool hanging
from the waist belt.
In the case of operation in a high place, it is
dangerous to drop the tool accidentally. If the hook
is deformed or hung from the wrong position, there
is danger that the hook will slip off and the tool
will fall.
Be careful to avoid danger.
In making a through hole, the power tool sometimes
shakes violently when the workpiece is pierced,
from example. Be careful you are not hurt by the
hook even if such situation happens.
9. RCD
The use of a residual current device with a rated
residual current of 30mA or less at all times is
recommended.
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.
The desired rotation speed can be pre-selected with
the speed control dial.
Turn the speed control dial clockwise for higher
speed and counterclockwise for lower speed.
(Fig. 5)
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.
(Fig. 7)
(Fig. 8)
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.
