Guidelines and Tips | Maintenance |
Regular periodic maintenance on your Model G9909 Electric Drill 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 that they are tight. If any screw is loose, tighten immediately.
When carbon brushes become worn, replace them promptly. The carbon brush should be kept clean so they can slide freely into the brush holder. To replace the carbon brushes, open the front cover and remove the screw from the brush holder.
