MAKITA GB602W (01) PDF Document

The following table outlines the technical specifications for the MAKITA GB602W bench grinder:

To ensure safe operation of your MAKITA GB602W, follow these guidelines:

KNOW YOUR POWER TOOL. Read the operator’s manual carefully to learn the applications, limitations, and 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. Never operate the tool with any guard removed. Ensure all guards are operating properly before each use.

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 areas and workbenches invite accidents.

AVOID DANGEROUS ENVIRONMENTS. Do not use power tools near gasoline or other flammable liquids, in damp or wet locations, or expose them to rain. Keep the work area well lighted.

KEEP CHILDREN AND VISITORS AWAY. All visitors should wear safety glasses and stay 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.

WEAR PROPER APPAREL. Do not wear loose clothing, neckties, or jewelry that can get caught in moving parts. Non-solid footwear is recommended. 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.

The MAKITA GB602W comes equipped with the following standard items:

Wrench 8-19 (1 piece)

Wrench 10-13 (1 piece)

Left Work Rest (1 piece)

Safety goggles (1 piece)

POWER SWITCH: An easy access On/Off switch for convenience and safety.

MOTOR: Powered by a precision-built electric induction motor with sufficient power to handle tough grinding jobs.

GRINDING WHEEL: Equipped with coarse and fine grinding wheels to suit most applications.

SAFETY EYE SHIELD AND SPARK DEFLECTOR: These are adjustable for operator convenience. Do not grind with the safety shield raised.

WORK REST: The work rests are independently adjustable to compensate for wheel wear. Before grinding, ensure they are adjusted so the object being ground is slightly above the center of the wheel.

COOLANT TRAY: When grinding, metal objects heat up quickly. Use the tray to cool the object frequently.

WORK LIGHT: A permanently mounted work light automatically lights the work area for safer grinding.

The primary components of the MAKITA GB602W include:

1. Adjustable knob

2. Safety eye shield

3. Saw blade sharpening kit

4. Adjustment bolts

5. Coolant tray

6. Auto-ON (work light)

7. Spark deflector (left)

8. Spark deflector (right)

9. Lamp cover

10. Safety eye shield with magnifying glass

11. Work rest (right)

12. Power switch

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

Step 2. Once the mounting arms are firmly in place, slide the shield bracket onto the eye shield-mounting arm.

Step 3. Tighten the adjustable knob, leaving it loose enough to allow the safety eye shield to be raised and lowered easily.

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

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.

Step 4. For the MAKITA GB602W, you also mount the blade work rest to the work rest bracket using two hex bolts, ensuring the same 1.6 mm maximum gap is maintained before tightening.

To sharpen tools effectively and avoid overheating:

Keep the tool on the work rest firmly at the correct angle to the 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.

Never sharpen or grind anything made of aluminum.

Step 1. Assemble and attach the saw blade sharpening kit as shown in the manual illustrations. Before using, ensure it is securely fastened.

Step 2. Place the saw blade between holder A and holder B.

Step 3. Secure the assembly on the screw with wing nut A.

Step 4. The angle adjustment can be made by loosening the hex bolts on the bevel scale plate. After adjusting the angle, tighten the hex bolts securely.

Step 5. Loosen wing nut B and slide holder B so that the “gullet” or slot between the saw blade teeth just comes in contact with the edge of the wheel.

Step 6. Slide the stopper so that it comes in contact with holder B and tighten wing nut B securely.

Step 1. Always disconnect the bench grinder from the power source before performing any replacement.

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

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

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

Step 5. To install a new grinding wheel, reverse the above procedure. Ensure the new wheel has a safe rated speed at least as high as the no load speed marked on the grinder’s data plate.

Step 6. Be sure the grinding wheel and outer flange are properly seated on the spindle shaft before tightening.

Step 1. When the light bulb is worn out, unfasten the screws that 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 new light bulb into the insert and turn it clockwise.

Step 4. Re-fix the lamp cover by reversing the order.

Check the following causes and corrective actions if the motor will not start:

1. Low voltage: Check the power line for proper voltage.

2. Open circuit in motor or loose connections: Inspect all lead connections on the motor for loose or open connections.

Burning spots or cracks may be caused by:

1. Improper type of grinding wheel: Try a wheel that is a softer style or has a coarser grit.

2. Improper feed rate: Slow down the rate of movement of the workpiece into the wheel.

3. Coolant required: Add an optional coolant system or introduce coolant by hand.
