●
When the pilot lamp flickers (at 0.2-second
intervals), check for and take out any foreign
objects in the charger’s battery connector. If there
are no foreign objects, it is probable that the
battery or charger is malfunctioning. Take it to
your authorized Service Center.
●
Since the built-in micro computer takes about 3
seconds to confirm that the battery being charged
with UC18YKSL is taken out, wait for a minimum
of 3 seconds before reinserting it to continue
charging. If the battery is reinserted within 3
seconds, the battery may not be properly charged.
BEFORE USE
Check the work area to make sure that it is clear of debris
and clutter.
Clear the area of unnecessary personnel. Ensure that
lighting and ventilation is adequate.
OPERATION
1.
Confirm the clutch dial position (see Fig. 5)
The three modes of screwdriver, drill and hammer
drill can be switched by the position of the clutch
dial in this unit.
(1)
When using this unit as a screwdriver, line up the
one of the numbers “1, 4, 7 ... 22” on the cap, or
the black dots, with the triangle mark on the outer
body.
(2)
When using this unit as a drill, align the clutch dial
drill mark “
” with the triangle mark on the outer
body.
(3)
When using this unit as a hammer drill, align the
clutch dial hammer mark “ ” with the triangle
mark on the outer body.
CAUTION
●
The clutch dial cannot be set between the numerals
“1, 4, 7 ... 22” or the black dots.
●
Do not use with the clutch dial numeral between
“22” and the black line at the middle of the drill
mark. Doing so may cause damage (See Fig. 6).
2.
Tightening torque adjustment
(1)
Tightening torque
Tightening torque should correspond in its
intensity to the screw diameter. When too strong
torque is used, the screw head may be broken or
be injured. Be sure to adjust the cap position
according to the screw diameter.
(2)
Tightening torque indication
The tightening torque differs depending on the
type of screw and the material being tightened.
The unit indicates the tightening torque with the
numbers “1, 4, 7 ... 22” on the cap, and the black
dots. The tightening toque at position “1” is the
weakest and the torque is strongest at the highest
number.
(3)
Adjusting the tightening torque
Rotate the clutch dial and line up the numbers “1,
4, 7 ... 22” on the clutch dial, or the black dots,
with the triangle mark on the outer body. Adjust
the clutch dial in the weak or the strong torque
direction according to the torque you need.
CAUTION
●
The motor rotation may be locked to cease while
the unit is used as drill. While operating the
hammer drill take care not to lock the motor.
●
Too long hammering may cause the screw broken
due to excessive tightening.
3.
Rotation to Impact changeover (See Fig. 5)
The “Rotation (Rotation only)” and “Hammer
( Rotation)” can be switched by aligning
the drill mark “
” or the hammer mark “ ” with
the triangle mark on the outer body.
To make holes in the metal, wood or plastic, switch
to “Rotation (Rotation only)”.
To make holes in bricks or concrete blocks, switch
to “Hammer ( Rotation)”.
CAUTION
●
If an operation which is normally performed at the
“Rotation” setting is performed at “Hammer“
setting,the effect of making holes does not only
increase but it may also damage the bit or other
parts.
