HOW TO USE

1. Mounting and dismounting of the bit.
(1) Mounting the bit
After inserting a driver bit, etc. into the keyless drill
chuck, firmly grasp the ring and tighten the sleeve
by turning it toward the right (in the clockwise
direction as viewed from the front). (See Fig. 4)
If the sleeve becomes loose during operation, tighten
it further. The tightening force becomes stronger
when the sleeve is tightened additionally.
(2) Dismounting the bit
Firmly grasp the ring and loosen the sleeve by
turning it toward the left (in the counter-clockwise
direction as viewed from the front). (See Fig. 4)
If the sleeve is tightened in a state where the clip
of the keyless chuck is opened to a maximum limit,
a click noise may occur. This is the noise that occurs
when the loosening of the keyless chuck is prevented
and is not a malfunction.
2. Confirm that the battery is mounted correctly.
3. Check the rotational direction
The bit rotates clockwise (viewed from the rear
side) by pushing the R-side of the selector button.
The L-side of the selector button is pushed to turn
the bit counterclockwise. (See Fig. 5). (The
R
marks are provided on the body.)
4. Switch operation
When the trigger switch is depressed, the tool
rotates. When the trigger is released, the tool stops.
(Fig. 6)
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.
When releasing the trigger of the switch,l the brake
will be applied for immediate stopping.
NOTE
A buzzing noise is produced when the motor is
about to rotate; This is only a noise, not a machine
failure.
CAUTIONS
While operating the cordless angle drill, take care
not to lock the motor.
If the motor is locked, immediately turn the power
off. If the motor is locked for a while, the motor
of battery may be burnt.
When pressing the tool against the object to be
drilled, take care not to touch the keyless chuck with
your hands.
NOTE
The use of the battery EB1230HL in a cold condition
(below 0 degree Centigrade) can sometimes result
in the weakened tightening torque and reduced
amount of work. This, however, is a temporary
phenomenon, and returns to normal when the
battery warms up.

MAINTENANCE AND INSPECTION

1. Inspecting the tool
Since use of as dull tool will degrade efficiency and
cause possible motor malfunction, sharpen or
replace the tool as soon as 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. Cleaning on the outside
When the Cordless Angle Drill is stained, wipe with
a soft dry cloth or a cloth moistened with soapy
water. Do not use chloric solvents, gasoline or paint
thinner, for they melt plastics.
