5. SPEED ADJUSTMENT
(Fig. 6)
This tool has a variable speed switch (c) that delivers higher
speed and torque with increased trigger pressure. Speed is
controlled by the amount of switch trigger depression. The
variable speed feature is particularly useful when starting
drilling. It also enables you to select the best speed for a
particular application. To limit the maximum speed of the
tool, rotate the dial (c) on the front of the trigger until the
desired setting is achieved.
6.SWITCHING ON AND OFF
(Fig. 6)
Start the tool by squeezing the variable speed trigger switch
(b). Release the trigger to stop the tool. If you press the lock
on button (d) while the trigger switch is depressed, the
switch is kept in the operating position. This is convenient
when continuous operating for extended periods of time is
required. To release the lock on button (d), press and
release the trigger switch (b).
7. FORWARD AND REVERSE ROTATION
CONTROL
(Fig. 6)
The forward/reverse control (a) determines the direction of
rotation of the tool. To select forward rotation for normal
drilling operation, push the forward/reverse control (a) as
indicated. Use reverse rotation to release a jammed drill bit
only.
Note:
When changing the position of forward/reverse
control (a) be sure the trigger is released and the motor is
stationary.
