REVERSING
LEVER
TRIGGER
SWITCH
LOCKING
BUTTON
release mechanism is working freely.
Do not lock the switch in the "ON" position while drilling by hand so that
you can instantly release the trigger switch if the bit binds in the hole.
Be sure to release the locking mechanism before disconnecting the
plug from the power supply. Failure to do so will cause the rotary
hammer to start immediately the next time it is plugged in. Damage or
injury may result.
The variable speed trigger switch permits speed control. The
farther the trigger switch is depressed, the higher the speed of the
rotary hammer.
The reversing lever is used to reverse the rotary hammer for
backing out screws or jammed bits. It is located above the trigger,
shown in Figure 2. To reverse the rotary hammer, turn it OFF and
push the reversing lever to the left (when viewed from the chuck
end). To position the lever for forward operation, turn the rotary
hammer OFF and push the lever to the right.
CAUTION: When reversing to clear a jammed bit be ready for
strong reactive torque.
Hammer/Drill Selector (DW566)
To switch tool from the drill only mode to the rotary hammer or
hammer only mode rotate the dial on the applicable symbol shown in
Figure 3.

NOTE: The selector must be in either drill, rotary hammer or hammer
mode at all times. There are no operable positions between the
positions.
SDS Chuck
To insert bit, insert shank of bit about 3/4" into chuck. Push and
rotate bit until it locks in place. The bit will be securely held.
To release bit, pull the collar back and remove the bit.
Operation
DRILLING
1. Always unplug the drill when attaching or changing bits or
accessories.
2. Be sure the material to be drilled is anchored or clamped firmly. If
drilling thin material, use a wood "back-up" block to prevent
damage to the material.
3. Always apply pressure in a straight line with the bit. Use enough
pressure to keep drill biting, but do not push hard enough to stall
the motor or deflect the bit.
4. Hold tool firmly to control the twisting action of the drill.
5. IF DRILL STALLS, it is usually because it is being overloaded or
improperly used. RELEASE TRIGGER IMMEDIATELY, remove
drill bit from work, and determine cause of stalling. DO NOT CLICK
TRIGGER OFF AND ON IN AN ATTEMPT TO START A
STALLED DRILL — THIS CAN DAMAGE THE DRILL.
6. To minimize stalling or breaking through the material, reduce
pressure on drill and ease the bit through the last fractional part of
the hole.
7. Keep the motor running when pulling the bit back out of a drilled
hole. This will help prevent jamming.
8. With variable speed drills there is no need to center punch the
point to be drilled. Use a slow speed to start the hole and
accelerate by squeezing the trigger harder when the hole is deep
enough to drill without the bit skipping out.
