5. How to select tightening torque and rotational speed
Use

Wood
Drilling
Metal
CAUTION
The selection examples shown in Table 5 should
be considered as general standard. As different
types of tightening screws and different materials
to be tightened are used in actual works proper
adjustments are naturally necessary.
When using the driver drill with a machine screw
at HIGH (high speed), a screw may damage or a
bit may loose due to the tightening torque is too
strong. Use the driver drill at LOW (low speed)
when using a machine screw.
NOTE
The use of the battery BSL1415 and BSL1815 in a
cold condition (below 0 degree Centigrade) can
sometimes result in the weakened tightening torque
and reduced amount of work.
a temporary phenomenon, and returns to normal
when the battery warms up.
6. Mounting and dismounting of the bit
(1) 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. 9).
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. 9).
CAUTION
When it is no longer possible to loosen the sleeve,
use a vise or similar instrument to secure the bit. Set
the clutch mode between 1 and 11, and then turn
the sleeve to the loose side (left side) while operating
the clutch. It should be easy now to loosen the sleeve.
7. Confirm that the battery is mounted correctly
8. 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. 10) (The
marks are provided on the body).

For drilling with a metal working drill bit.
9. Switch operation
When the trigger switch 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.
NOTE
A buzzing noise is produced when the motor is about
to rotate; This is only a noise, not a machine failure.
10. Using the hook
The hook is used to hang up the power tool to your
waist belt while working.
CAUTION
When using the hook, hang up the power tool
firmly not to drop accidentally.
If the power tool is dropped, it may lead to an
accident.
When carrying the power tool with hooked to your
waist belt, do not fit any bit to the tip of power
tool. If the sharp bit such as drill is fitted to the
power tool when carrying it with hooked to your
waist belt, you will be injured.
Install securely the hook. Unless the hook is securely
installed, it may cause an injury while using.
(1) Removing the hook.
Remove the screws fixing the hook with screw
driver. (Fig. 11)
(2) Replacing the hook and tightening the screws.
Install securely the hook in the groove of power
tool and tighten the screws to fix the hook firmly.
(Fig. 12)

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.
