8. Attaching the hook. (Optional accessory)
For hook (side-attaching) (Fig. 7)
Fix the hook firm ly on the desired side of the gear
cover using M 10 bolt w hich is supplied w ith hook.
For hook (A) (top-attaching) (Fig. 8)
To attach the hook (A), it is necessary to disassem ble
the handle portion w hich covered the tool's electrical
system . For your continued safety and electrical
shock protection, installing the hook (A) on this drill
should ONLY be perform ed by a Hitachi Authorized
Service Center.
CAUTION:
When the pow er tool is used w ith a hook fixed to
it, pay attention to the follow ing points:
Before hanging the m ain unit from the w aist belt,
✁
m ake sure that the drill has com e to a com plete
stop.
While it is suspended from the w aist belt, the pow er
plug m ust be disconnected from the pow er source.
Do not w alk about w ith the pow er tool hanging
✁
from the w aist belt.
In the case of operation in a high place, it is
✁
dangerous to drop the tool accidentally. If the hook
is deform ed or hung from the w rong position, there
is danger that the hook w ill slip off and the tool
w ill fall.
Be careful to avoid danger.
In m aking a through hole, the pow er tool som etim es
✁
shakes violently w hen the w orkpiece is pierced,
from exam ple. Be careful you are not hurt by the
hook even if such situation happens.

HOW TO USE

1. Sw itch 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 am ount that the trigger sw itch is
pulled. Speed is low w hen the trigger sw itch is
pulled slightly and increases as the trigger sw itch
is pulled m ore.
The desired rotation speed can be pre-selected w ith
✁
the speed control dial.
Turn the speed control dial clockw ise for higher
speed and counterclockw ise for low er speed.
(Fig. 5)
Pulling the trigger and pushing the stopper, it keeps
✁
the sw itched-on condition w hich is convenient for
continuous running. When sw itching off, the stopper
can be disconnected by pulling the trigger again.
2. Drilling
When drilling, start the drill slow ly, and gradually
✁
increasing speed as you drill.
Alw ays apply pressure in a straight line w ith the
✁
bit. Use enough pressure to keep drilling, but do
not push hard enough to stall the m otor or deflect
the bit.
To m inim ize stalling or breaking through the
✁
m aterial, reduce pressure on drill and ease the bit
through the last part of the hole.
If the drill stalls, release the trigger im m ediately,
✁
rem ove the bit from the w ork and start again. Do
not click the trigger on and off in an attem pt to
start a stalled drill. This can dam age the drill.
The larger the drill bit diam eter, the larger the
✁
reactive force on your arm .
Be careful not to lose control of the drill because
of this reactive force.
To m aintain firm control, establish a good foothold,
use side handle, hold the drill tightly w ith both
hands, and ensure that the drill is vertical to the
m aterial being drilled.
M AINTENANCE AND INSPECTION
1. Inspecting the drill bits
Since use of an abraded drill bits w ill cause m otor
m alfunctioning and degraded efficiency, replace the
drill bits w ith a new one or resharpening w ithout
delay w hen abrasion is noted.
2. Inspecting the mounting screw s
Regularly inspect all m ounting screw s and ensure
that they are properly tightened. Should any of the
screw s be loose, retighten them im m ediately. Failure
to do so could result in serious hazard.
3. M aintenance of the motor
The m otor unit w inding is the very " heart" of the
pow er tool. Exercise due care to ensure the w inding
does not becom e dam aged and/or w et w ith oil or
w ater.
4. Inspecting the carbon brushes
For your continued safety and electrical shock
protection, carbon brush inspection and replacem ent
on this tool should ONLY be perform ed by a Hitachi
Authorized Service Center.
