When setting the shift knob to "HIGH" (high speed)
and the position of the cap is "17" or "22", it may
happen that the clutch does not engaged and that
the motor is locked. In such a case, please set the
shift knob to "LOW" (low speed).
4. The scope and suggestions for uses

CAUTION:
The selection examples shown in Table 7 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 tightning torque is too
strong. Use the driver drill at LOW (low speed)
when using a machine screw.
NOTE:
The use of the battery EB9H, EB926H, EB930H,
EB1222HL, EB1226HL, EB1230HL, EB1426H, EB1430H,
EB1826HL and EB1830HL 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.

6. Mounting and dismounting of the bit
(1) Mounting the bit
Loosen the sleeve by turning it toward the left (in
the counterclockwise direction as viewed from the
front) to open the clip on the keyless chuck. After
inserting a driver bit, etc., into the keyless drill
chuck, and tighten the sleeve by turning it toward
the right (in the clockwise direction as viewed from
the front) (See Fig. 10).
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
Loosen the sleeve by turning it toward the left (in
the counterclockwise direction as viewed from the
front), and then take out the bit ect (See Fig. 10).
