Using A Reversible Drill Continued
10) Use only genuine Dewalt spare parts or parts which perform
equivalently. Do not make temporary or permanent repairs with
unauthorized parts.
11) Do not lock, tape, wire, etc., the on/off trigger in the run
position. The trigger must always be free to return to
the "off" position when it is released.
12) Always shut off the air supply to the tool and depress the
trigger to release air from the feed hose before fitting,
adjusting or removing the working attachment.
13) Check hoses and fittings regularly for wear. Replace if
necessary. Do not carry the tool by its hose. Ensure the
hand is removed from the on/off trigger when carrying
the tool with the air supply connected.
14) Take care against entanglement of moving tool parts
with clothing, ties, hair, cleaning rags, etc. This will
cause the body to be drawn towards the tool and can
be very dangerous.
15) Safe working practices and observe all relevant legal
requirements when installing, using or maintaining the tool.
16) Only install the tool when an easily accessible and easily
operable on/off switch is incorporated in the air supply.
17) Take care that the tool exhaust air does not cause problems
or blow onto another person.
18) Never lay a tool down unless the working attachment has
stopped moving.
19) Do not start the tool until the bit is securely clamped in the
chuck jaws.
20) Do not start the tool until the bit is in contact with the surface
being drilled.
21) Use drill bits appropriate for the material being drilled.
22) Do not force the drill. If drilling becomes difficult, professional
re-sharpening or replacement of the bit may be necessary.
23) Worn/blunt bits should not be used as this condition contributes
to increased vibration and possible tool breakage. A bit that
breaks can cause injury.
PRE-START CHECKLIST
• Drain water from air compressor tank and condensation from
air lines. (Please refer to air compressor's operation manual.)
• Lubricate the tool. (Please refer to the "Maintenance" section
in the manual.)
WARNING: Risk of unsafe operation. Firmly grasp air hose
with hand when installing or disconnenting to prevent hose whip.
WARNING: Risk of bursting. Too much air pressure causes
a hazardous risk of bursting. Check the manufacturer's maximum
pressure rating for air tools and accessories. The regulator output
pressure must never exceed the maximum pressure rating.
INSTALLING/REMOVING DRILL BITS
• ALWAYS disconnect drill from air supply before changing drill bits!
DRILL BIT
• To install the drill bit, loosen the chuck jaws by turning the front
of the chuck counter-clockwise, while holding the rear in place.
• Carefully insert drill bit into chuck. To ensure proper
operation,ensure that the bit is entered between the jaw teeth.
