OPERATIONS
Changing Bits
1. Remove the chuck key from the hold-
er on the power cord.
Operating this equipment has the
potential for flying debris to cause eye
injury. Always wear safety glasses or
goggles when operating equipment.
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).
2. Insert the chuck key into one of the
three holes located on the side of the
chuck.
3. Turn the chuck key counterclockwise.
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 opening.
5. Turn the chuck key clockwise until the
jaws close tightly around the bit or dri-
ver. 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.
6. To release the bit or driver, insert the
chuck key and turn counter-clock-
wise.
Like all power tools, there is danger
associated with the Model G9909.
Accidents are frequently caused by
lack of familiarity or failure to pay
attention. Use this tool with respect
and caution to lessen the possibility of
operator injury. If normal safety pre-
cautions are overlooked or ignored,
serious personal injury may occur.
Operating this equipment has the
potential to propel debris into the air
which can cause eye injury. Always
wear safety glasses or goggles
when operating equipment. Be cer-
tain the safety glasses you wear
meet the appropriate standards of
the American National Standards
Institute (ANSI).
The Model H0777 was specifically
designed for boring holes. DO NOT
MODIFY
AND/OR
USE
THIS
MACHINE FOR ANY OTHER PUR-
POSE. Modifications or improper
use of this tool will void the warran-
ty. If you are confused about any
aspect of this machine, DO NOT use it
until you have answered all your ques-
tions. Serious personal injury may
occur.

MAINTENANCE
Guidelines and Tips
Maintenance
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.
Regular periodic maintenance on your
Model H0777 Heavy-Duty 1⁄2" Electric Drill
will ensure its optimum performance.
Make a habit of inspecting your drill each
time you use it.
Periodically check all screws to be sure
they are tight. If any screw is loose, tighten
immediately.
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.
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.
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.
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.
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.
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 1⁄2" Electric Drill.
