will ensure its optimum performance.
Make a habit of inspecting your drill each
time you use it.
Avoid overloading the drill. Always use
sharpened drill bits. Do not apply
excessive pressure to the drill while
using. If the speed drops abnormal-
ly, decrease pressure immediately. If
the bit stops abruptly or becomes
blocked, release the trigger at once.
Ensure the safety of the workplace.
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 other-
wise clamp to avoid injury. Do not
attempt to hold workpiece by hand.
Inspect the drill before use. Run the drill
before using to ensure all parts are
running smoothly and there are no
abnormal sounds or sparks. If any
defect is found, have unit serviced.
Know your worksite. Only drill as deep
as necessary. Check behind walls
for wires, other electrical hazards, or
plumbing.
Continuous use of a worn or damaged bit
will not only decrease working efficiency,
but also overload the motor, so the bit must
be frequently checked. Replace the bit if it
is worn or damaged.
Periodically check all screws to be sure
they are tight. If any screw is loose, tighten
immediately.
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.
A damp cloth is ideal for cleaning the drill
body. Avoid excessive moisture, especially
in areas around the ventilation holes. Also,
avoid the use of solvents while cleaning
the drill body. Solvents may damage the
plastic.
Store tool in a dry place when not in use.
Moisture in the internal parts of the drill
may cause electrical problems.
Finally, leave lubrication and repair to qual-
ified service professionals. This will ensure
that you get years of faithful service from
your Grizzly Heavy-Duty 1 ⁄
