DeWalt D21620 Handbuch Seite 25

Mounting the drill guard (fig. C)
• Hold the guard (7) in front of the tool holder,
aligning the slots in the holes with the holes in the
machine.
• Fit the screw (13) into the hole (14) located in the
front of the frame.
• Fit a knob (15) into each of the holes (16) located
at both sides of the frame.
• Do not tighten the fasteners firmly as the drill
guard must be able to rise and lower as required.
Always use the drill guard.
Fitting the lubrication system (fig. D)
The lubrication system can be used for horizontal
drilling applications (the drill being used vertically).
• Loosen the knob (17) and turn the bracket (18) in
position. Tighten the knob.
• Hold the cutting fluid reservoir (19) against the
bracket and push it in its place.
• Place the hose (20) between the cutting fluid
reservoir (19) and the connection in the frame (21).
In order to use the lubrication system, it must be filled
with a sufficient amount of cutting fluid.
• Make sure the flow regulator (22) is closed.
• Unscrew the cap (23).
• Fill the container with cutting coolant diluted with
water.
• Screw the cap (23) back on.
Do not use the lubrication system in
vertical or overhead drilling applications.
Fitting the safety strap (fig. E)
• Pass the safety strap (24) through the slot (25).
• Wrap the strap around the workpiece.
• Securely tighten the strap using the buckle (26).
Always use the safety strap.
Inserting and removing an accessory (fig. F)
The tool holder accepts annular cutters with a
19 mm shank with one or more flats.
The teeth of a cutter are very sharp and
can be dangerous.
• In order to fit an accessory it is necessary to raise
the the guard (7) to its highest position.
• Slide the pilot pin through the hole in the center
of the cutter shank.
• Turn the tool holder locking sleeve (27) clockwise
and hold it in position.
• Insert the shank of the accessory (28) as far into
the tool holder (6) as possible.
• Release the locking sleeve.
• Twist the accessory until it locks in position.
• In order to remove the accessory, twist the
locking sleeve clockwise and take out the cutter.
Setting the speed (fig. G)
The machine is equipped with a 2-gear selector to
vary the speed/torque ratio.
• Depress the slider (29) in order to allow to
change the gear.
- Slide the slider (29) up for a low speed and a
high torque (holes from 32 to 50 mm).
- Slide the slider down for a high speed and a
low torque (holes from 12 to 30 mm).
• You may have to rotate the tool holder slightly
before the gear engages.
• Do not change gears at full speed or during use.
Instructions for use
Always observe the safety instructions
and applicable regulations.
• Apply only a gentle pressure to the tool.
Excessive force does not speed up drilling but
decreases tool performance and may shorten
tool life.
• It the accessory jams, stop the motor and gently
raise the accessory out of the workpiece before
resuming work.
• Always use the safety strap.
• Always use the drill guard.
Prior to operation:
• Try a few simple projects using scrap material
until you develop a "feel" for the machine.
Switching on and off (fig. A & H)
In order to operate properly, the machine has to be
switched following the procedure as described below.
