Use
Machine screw
Driving
Wood screw
Wood
Drilling
Metal
CAUTION
The selection examples shown in Table 2 should
be utilized as a general standard. As different types
of tightening screws and different materials to be
tightened are used in actual works, proper
adjustments are naturally necessary.
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. 8)
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. 8)
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 10 and then
turn the sleeve to the loose side (left side) while
operating the clutch. It should be easy now to
loosen the sleeve.
NOTE
There is a plus driver bit on side of the main unit.
The bit can be removed by pulling it forward. After
using the bit, make sure to firmly attach it to the
main body again.
7. Confirm that the battery is mounted correctly.
8. Check the rotation 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. 9). (The
marks are provided on the body.)
CAUTION:
Make sure to firmly switch the selector button. If
it is not switched firmly, the drill may not rotate
even if the switch is turned on.
9. Switch operation
When the trigger switch is pulled, the tool rotates.
When the trigger is released, the tool stops.

and
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 peep sound may be produced when the motor
is about to rotate; This is only a noise, not a machine
failure.

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 driver 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,
as they melt plastics.
4. Storage
Store the driver drill in a place in which the tempera
ture is less than 40°C and out of reach of children.
