SECTION 4: OPERATIONS
Always wear safety glasses or gog-
gles when operating tools. Everyday
!
glasses or reading glasses only have
impact resistant lenses, they are not
safety glasses. Be certain the safety
glasses you wear meet the appropriate
standards of the American National
Standards Institute (ANSI).
Unplug the drill before performing
any drill bit removal, cleaning, or
maintenance.
Drilling Guidelines and Tips
•
Avoid overloading the drill. Always
use sharpened drill bits and fre-
quently clear chips and shavings
from the hole drilled. Do not apply
excessive pressure to the drill. If the
speed drops abnormally, decrease
pressure immediately. If the bit
stops abruptly or becomes blocked,
release the trigger at once.
Changing Bits
1. DISCONNECT THE DRILL FROM
POWER!
2. Insert the chuck key into one of the
holes located on the side of the
chuck.
•
Ensure the safety of the work-
place. Clear the work area of all
parts and debris that may cause
injury by flying objects. Securely fix
the object to be drilled or fastened in
a vise or clamp to avoid injury.
3. Turn the chuck key counter-clock-
wise. This will cause the three chuck
jaws to open. When the chuck jaws
are at the approximate diameter of
the bit or driver, insert the shank end
of the bit or driver into the jaw open-
ing.
•
•
Inspect the drill before use. Run
the drill before using to ensure that
the drill bit is centered in the chuck.
5. Turn the chuck key clockwise until
the jaws close tightly around the bit
or driver. Never “power tighten” which
is holding the chuck while running the
drill. This can cause serious injury to
the operator’s hands. Check for tight-
ness periodically while using the tool.
Know your worksite. Only drill as
deep as necessary. Check behind
walls for wires, other electrical haz-
ards, or plumbing.
•
Use drill in a safe environment.
Never use the drill where paper,
flammable gasses/liquids exist, or
where any ignition hazard exists.
6. To release the bit or driver, insert the
chuck key and turn counter-clock-
wise.

in serious injury.
Brush Replacement
Under extreme use, the Model H7859 may
require brush replacement, as the motor
may lose power or growl during operation.
The following steps will guide you through
brush replacement.
Regularly clean your drill and make sure
that no dust or grime builds up in the motor
ventilation holes. If these holes become
blocked, the motor will wear down faster
than necessary. A good way to clean ven-
tilation holes is to blow them out with com-
pressed air. Just be sure to wear safety
glasses when you do this.
1. Unplug the drill.
2. Remove two brush caps.
3. Replace two brushes.
4. Reinstall two brush caps.
5. Test drill operation.
Store tool in a dry place when not in use.
Moisture in the internal parts of the drill
may cause electrical corrosion or a short
circuit.
