NOTE:
Use the lowest torque setting (1) first and increase
the number through to the highest setting (11) to seat the
fastener at the desired depth. The lower the number, the
lower the torque output.
2. Reset the torque adjustment collar (E) to the appropriate
number setting for the torque desired. Make a few practice
runs in scrap or unseen areas to determine the proper position
of the torque adjustment collar.
NOTE: The torque adjustment collar may be set to any number
at any time.
Hammerdrill Operation (Fig. 5)
1. Select the desired speed/torque range using the gear shifter
to match the speed and torque to the planned operation. Set
the torque adjustment collar (E) to the hammer symbol.
2. Select the high speed 3 setting by sliding the gear shifter (F)
back (away form the chuck).
3. When drilling, use just enough force on the hammer to
keep it from bouncing excessively. Prolonged and too much
force on the hammer will cause slower drilling speeds and
potential overheating.
4. Drill straight, keeping the bit at a right angle to the work. Do
not exert side pressure on the bit when drilling as this will
cause clogging of the bit flutes and a slower drilling speed.
5. When drilling deep holes, if the hammer speed starts to drop
off, pull the bit partially out of the hole with the tool still
running to help clear debris from the hole.
6. For masonry, use carbide-tipped bits or masonry bits. A
smooth, even flow of dust indicates the proper drilling rate.
MAINTENANCE
Your DeWALT power tool has been designed to operate over a
long period of time with a minimum of maintenance. Continuous
satisfactory operation depends upon proper tool care and regular
cleaning.
WARNING: To reduce the risk of
serious personal injury, turn tool
off and disconnect battery pack
before making any adjustments or
removing/installing attachments or
accessories. An accidental start-up
can cause injury.
The charger and battery pack are not serviceable.
Lubrication
Your power tool requires no additional lubrication.
securely in anticipation of a sudden
reaction.
Proper hand position requires one hand on the main handle (R),
with the other hand on the side handle(G).
Drill Operation (Fig. 4)
WARNING: To reduce the risk
of serious personal injury, turn
tool off and disconnect tool from
power source before making any
adjustments or removing/installing
attachments or accessories.
WARNING: To reduce the risk of
personal injury, ALWAYS ensure
workpiece is anchored or clamped
firmly. If drilling thin material, use a wood
“back-up” block to prevent damage to
the material.
1. Select the desired speed/torque range using the gear shifter
to match the speed and torque to the planned operation. Set
the torque adjustment collar (E) to the drill symbol.
2. For WOOD, use twist bits, spade bits, power auger bits or
hole saws. For METAL, use high-speed steel twist drill bits or
hole saws. Use a cutting lubricant when drilling metals. The
exceptions are cast iron and brass which should be drilled dry.
3. Always apply pressure in a straight line with the bit. Use
enough pressure to keep the drill bit biting, but do not push
hard enough to stall the motor or deflect the bit.
4. Hold tool firmly with both hands to control the twisting
action of the drill.
5. IF DRILL STALLS, it is usually because it
is being overloaded. 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. Keep the motor running when pulling the bit back out of a
drilled hole. This will help prevent jamming.
Screwdriver Operation (Fig. 3)
1. Select the desired speed/torque range using the three-speed
gear shifter (F) on the top of the tool. If using the torque
adjustment collar (E), initially set the three-speed gear
shifter to speed 2 or 3. This ensures effective control over the
fastener allowing the screw to be seated correctly and set to
specification. Speed 1 will provide the same clutching torque
as speeds 2 and 3. However, for optimum performance of the
electronic clutch, speeds 2 and 3 are preferred.
