Guidelines and Tips | Maintenance |
Regular periodic maintenance on your Model H0777
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
