5. The scope and suggestions for uses
The usable scope for various types of work based on the mechanical structure of this unit is shown in Table 4.
CAUTION
䡬
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.
䡬
When using the impact 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 impact driver drill at LOW (low speed)
when using a machine screw.
NOTE
The use of the battery 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.
7. 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. 8).
䡬
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 etc (See Fig. 8).
NOTE
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.
CAUTION
䡬
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 7 and then turn the
sleeve to the loose side (left side) while operating the
clutch. It should be easy now to loosen the sleeve.
8. Automatic spindle-lock mechanism
This unit has automatic spindle-lock mechanism for
quick bit changes.
9. Confirm that the battery is mounted correctly
