Switch
To start tool, depress the trigger switch, shown in
Figure 1.
To stop tool, release the switch. The variable speed
trigger switch permits speed control. The farther
the trigger switch is depressed, the higher the
speed of the tool.
To lock the switch in the on position for continuous
operation, depress the trigger switch and push up
the locking button. The tool will continue to run.
To turn the tool off, from a locked on condition,
squeeze and release the trigger once. Before using
the tool (each time), be sure that the locking button
release mechanism is working freely.
WARNING: Be sure to release the locking mechanism before disconnecting the
plug from the power supply. Failure to do so will cause the tool to start immediately
the next time it is plugged in. Damage or injury could result.
The reversing lever is used to reverse the tool for backing out screws. It is located
above the trigger, shown in Figure 1. To reverse the screwdriver, turn it off and push
the reversing lever to the right (when viewed from the back of the tool). To position the
lever for forward operation, turn the tool off and push the lever to the left.
Dead Spindle Action
All D
E
WALT screwdrivers provide a dead output spindle to permit fasteners to be
located easily in the driving accessory. Clutches are held apart by light spring
pressure permitting the driving clutch to rotate without turning the driven clutch and
accessory. When sufficient forward pressure is applied to the unit, the clutches
engage and rotate the spindle and accessories. A reversing switch makes it possible
to drive or loosen either right or left hand screws.
