The following table outlines the product specifications for the MAKITA GB801:

To ensure safe operation of the MAKITA GB801, follow these rules:

KNOW YOUR POWER TOOL: Read the operator’s manual carefully and learn the applications and limitations as well as specific potential hazards.

GUARD AGAINST ELECTRICAL SHOCK: Prevent body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerator enclosures.

KEEP GUARDS IN PLACE: Ensure all guards are in working order and never operate the tool with any guard or cover removed.

REMOVE ADJUSTING KEYS AND WRENCHES: Form a habit of checking that keys and adjusting wrenches are removed from the tool before turning it on.

KEEP THE WORK AREA CLEAN: Cluttered work areas and benches invite accidents.

AVOID DANGEROUS ENVIRONMENTS: Do not use power tools near flammable liquids or in damp or wet locations. Keep the work area well lighted.

KEEP CHILDREN AND VISITORS AWAY: All visitors should wear safety glasses and be kept a safe distance from the work area.

DON’T FORCE THE TOOL: It will do the job better and safer at the rate for which it was designed.

USE THE RIGHT TOOL: Do not force the tool or attachment to do a job for which it was not designed.

INSPECT EXTENSION CORDS PERIODICALLY: Replace extension cords immediately if they are damaged.

WEAR PROPER APPAREL: Do not wear loose clothing, neckties, or jewelry that can get caught in moving parts. Wear protective hair covering to contain long hair.

ALWAYS WEAR SAFETY GLASSES WITH SIDE SHIELDS: Everyday eyeglasses are NOT safety glasses.

PROTECT YOUR LUNGS: Wear a face or dust mask if the cutting operation is dusty.

PROTECT YOUR HEARING: Wear hearing protection during extended periods of operation.

DON’T ABUSE THE CORD: Never carry the tool by the cord or yank it to disconnect it from the receptacle. Keep the cord away from heat, oil, and sharp edges.

DO NOT OVERREACH: Keep proper footing and balance at all times.

MAINTAIN TOOLS WITH CARE: Keep tools sharp and clean for the best and safest performance.

NEVER LEAVE THE TOOL RUNNING UNATTENDED: Turn the power off and do not leave the tool until it comes to a complete stop.

AVOID ACCIDENTAL STARTING: Ensure the switch is off before plugging in the tool.

USE RECOMMENDED ACCESSORIES: The use of improper accessories may cause risk of injury.

DIRECTION OF FEED: Be aware of wheel rotation direction; never grind without the work rest being properly set.

NEVER STAND ON THE TOOL: Serious injury could occur if the tool is tipped or if the wheel is unintentionally contacted.

The safety symbols on the MAKITA GB801 indicate the following levels of hazard:

Additionally, a specific symbol indicates: DO NOT EXPOSE TO RAIN OR USE IN DAMP LOCATIONS.

The following items are standard equipment for the MAKITA GB801:

Wrench 8-24 (1 unit)

Wrench 10-13-17 (1 unit)

Safety goggles (1 unit)

To mount the safety eye shields on the MAKITA GB801, use the following components and procedure:

Components: 1. Eye shield mounting arm, 2. Hex bolt, 3. Adjustable knob, 4. Safety eye shield.

Procedure:

Step 1. Mount the left and right eye shield-mounting arm to the inside of the wheel guards using the clamp Brackets, hex bolts (M6 X 30 mm), and washers (6 mm).

Step 2. Use the provided illustrations in the manual as a guide to determine which eye shield mounting arm is mounted on the left and which is mounted on the right of the grinder.

Step 3. Once the eye shield mounting arms are firmly in place, slide the shield bracket onto the eye shield-mounting arm.

Step 4. Tighten the adjustable knob, leaving it loose enough to allow the safety eye shield to be raised and lowered easily.

To install the work rest on the MAKITA GB801:

Step 1. Mount the work rest to the work rest bracket using the two provided hex bolts.

Step 2. Before tightening the bolts, adjust the gap between the grinding wheel and the work rest to a maximum of 1.6 mm.

Step 3. Tighten the bolts securely.

When operating the MAKITA GB801, keep the following in mind:

Always wear safety goggles or safety glasses with side shields. Use a dust mask if the operation is dusty.

Do not sharpen or grind anything made of aluminum.

Grinders remove material rapidly, so pressure is the key to efficient grinding. To sharpen a tool and avoid overheating, follow these steps:

Keep a tool on the work rest firmly at the correct wheel.

Keep the object in constant motion, moving it at an even pace.

Never force a tool against the grinding wheel.

Keep the tool cool by using either a cooling tray or a pan of water.

The grinding wheel should rotate “into” the object being sharpened.

The MAKITA GB801 allows for balancing the grinding wheel. When the grinding wheel only is mounted, the heaviest section will assume the lowest position. Follow these steps for balancing:

Step 1. Mark the heaviest section of the wheel.

Step 2. Install the flange and balance weight.

Step 3. The balance weight should be positioned above the marked heaviest section.

Step 4. Temporarily tighten the flange with the installing nut.

Step 5. Move the balance weight so that when the wheel is turned, it does not stop at the same place at random.

Step 6. Fasten the stop screws on the balance weight and firmly tighten the flange nut.

If you must replace a grinding wheel on the MAKITA GB801, follow these instructions:

Step 1. Ensure the new wheel has a safe rated speed at least as high as the “no load speed” RPM marked on the data plate of the grinder.

Step 2. Remove the wheel cover by loosening the screws with holding the nut wrench.

Step 3. Loosen the wheel nut in a clockwise direction for the left side and a counterclockwise direction for the right side using the provided wrench.

Step 4. Remove the outer flange and the old grinding wheel.

Step 5. Install the new grinding wheel and reverse the above procedure.

Step 6. Ensure the grinding wheel and outer flange are properly seated on the spindle shaft.

To replace the worklight bulb on the MAKITA GB801:

Step 1. Unfasten the screws which fix the lamp cover.

Step 2. Gently remove the bulb from the holder by pushing it in and turning it anticlockwise.

Step 3. To replace, gently push the light bulb into the insert and turn clockwise.

Step 4. Fix the lamp cover back in place by reversing the order.

Dressing a wheel is done to renew sharpness or to true up the face of the wheel on the MAKITA GB801:

Step 1. Set the work rest of the bench grinder at a slight angle and brace the wheel-dressing tool against it.

Step 2. Do not make contact with the grinding wheel until after you have turned on the motor and the wheel is rotating at full speed.

Step 3. Press the dressing tool slightly against the rotating wheel until you get a bite, then move slowly from side across the wheel.

Step 4. A small bite and many passes are better than a big bite and one pass.

Step 5. Work cautiously and hold the dresser with force on the work rest. Do not use excessive pressure against the grinding wheel.
