IV. OPERATION
[Main Body]
Switch Operation
1.
The speed increases with the amount
of depression of the trigger. When
beginning work, depress the trigger
slightly to start the rotation slowly.
2. A feedback electronic controller is
used to give a strong torque even in
low speed.
3. The brake operates when the trigger
is released and the motor stops
immediately.
NOTE:
• When the brake operates, a braking
sound may be heard. This is normal.
• Sparks from the motor brush may be
visible through the body vent holes on
the back of the tool during switching
and braking due to the load imposed
on the motor. This does not indicate a
problem with the tool.
CAUTION:
When operating the tool by pulling the
trigger, there may be a momentary lag
before rotation starts. This does not
signal a malfunction.
* This lag occurs as the tool’s circuitry
starts up when the trigger is pulled for
the first time after installing a new bat
-
tery pack or after the tool has not been
used for at least 1 minute (or at least 5
minutes when the LED is on). Rotation
will start without any lag during second
and subsequent operations.

Lever Operation
Forward
Reverse
Switch lock
CAUTION:
To prevent damage, do not operate
Forward/Reverse lever until the bit
comes to a complete stop.
Forward Rotation Switch
Operation
1. Push the lever for forward rotation.
2. Depress the trigger switch slightly to
start the tool slowly.
3. The speed increases with the
amount of depression of the trigger
for efficient tightening of screws and
drilling. The brake operates and the
chuck stops immediately when the
trigger is released.
4. After use, set the lever to its center
position (switch lock).
Reverse Rotation Switch
Operation
1. Push the lever for reverse rotation.
Check the direction of rotation be-
fore use.
2. Depress the trigger switch slightly to
start the tool slowly.
3. After use, set the lever to its center
position (switch lock).
Clutch Torque Setting
Adjust the torque to one of the 18
clutch settings or “
” position (EY7442,
EY7450).
Adjust the torque to one of the 18 clutch
settings or “
”, “
” position (EY7950).
NOTE:
Always make sure to stop operation
of the tool and disengage it from the
work, when you select Hammering
mode from Drilling mode or when you
shift to Drilling mode from Hammering
mode by rotating clutch handle.
