General Power Tool Safety Warnings

WARNING: Read all safety warnings and instructions. Failure to follow warnings may result in electric shock, fire, and/or serious injury. Save these instructions for future reference.

The term "power tool" refers to your mains-operated or battery-operated tool.

Work Area Safety

1. Keep work area clean and well lit.
2. Do not operate power tools in explosive atmospheres (flammable liquids, gases, dust). Power tools create sparks that can ignite dust or fumes.
3. Keep children and bystanders away. Distractions can cause loss of control.

Electrical Safety

1. Power tool plugs must match the outlet. Never modify the plug. Do not use adapter plugs with earthed tools.
2. Avoid body contact with earthed surfaces (pipes, radiators, ranges, refrigerators).
3. Do not expose power tools to rain or wet conditions.
4. Do not abuse the cord. Keep cord away from heat, oil, sharp edges, or moving parts. Damaged or entangled cords increase the risk of electric shock.
5. When operating outdoors, use an extension cord suitable for outdoor use.
6. If operating in a damp location, use a ground fault circuit interrupter (GFCI) protected supply.

Personal Safety

1. Stay alert, watch what you are doing, and use common sense. Do not use a power tool when tired or under the influence of drugs, alcohol, or medication.
2. Use personal protective equipment. Always wear eye protection. Use dust masks, non-skid safety shoes, hard hats, or hearing protection as appropriate.
3. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power or battery pack, picking up, or carrying the tool.
4. Remove any adjusting key or wrench before turning the power tool on.
5. Do not overreach. Keep proper footing and balance at all times.
6. Dress properly. Do not wear loose clothing or jewelry. Keep hair, clothing, and gloves away from moving parts.
7. If dust extraction facilities are provided, ensure they are connected and properly used.

Power Tool Use and Care

1. Do not force the power tool. Use the correct power tool for your application.
2. Do not use the power tool if the switch does not turn it on and off. Dangerous tools must be repaired.
3. Disconnect the plug from the power source and/or battery pack before making adjustments, changing accessories, or storing the tool.
4. Store idle power tools out of reach of children and untrained users.
5. Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tool's operation. Have damaged tools repaired before use.
6. Keep cutting tools sharp and clean. Properly maintained cutting tools are less likely to bind and are easier to control.
7. Use the power tool, accessories, and tool bits in accordance with these instructions, taking into account working conditions and the work to be performed.
8. Have your power tool serviced by a qualified repair person using only identical replacement parts.
9. Follow instructions for lubricating and changing accessories.
10. Keep handles dry, clean, and free from oil and grease.

USE PROPER EXTENSION CORD: Ensure your extension cord is in good condition and heavy enough to carry the current your product will draw. An undersized cord can cause voltage drop, loss of power, and overheating. Refer to Table 1 for correct gauge based on cord length and amperage rating.

Table 1: Minimum gauge for cord

ROTARY HAMMER SAFETY WARNINGS

1. Wear ear protectors. Exposure to noise can cause hearing loss.
2. Use auxiliary handle(s), if supplied. Loss of control can cause personal injury.
3. Hold power tool by insulated gripping surfaces when performing operations where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts "live" and could give the operator an electric shock.
4. Wear a hard hat (safety helmet), safety glasses, and/or face shield. Ordinary eye or sun glasses are NOT safety glasses. A dust mask and thickly padded gloves are also highly recommended.
5. Be sure the bit is secured in place before operation.
6. Under normal operation, the tool produces vibration. Screws can come loose easily, causing breakdown or accident. Check tightness of screws carefully before operation.
7. In cold weather or when the tool has not been used for a long time, let the tool warm up for a while by operating it under no load. This will loosen up the lubrication.
8. Always be sure you have a firm footing.
9. Be sure no one is below when using the tool in high locations.
10. Hold the tool firmly with both hands.
11. Keep hands away from moving parts.
12. Do not leave the tool running. Operate the tool only when hand-held.
13. Do not point the tool at anyone in the area when operating. The bit could fly out and injure someone seriously.
14. Do not touch the bit or parts close to the bit immediately after operation; they may be extremely hot and could burn your skin.
15. Some materials contain chemicals which may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.

SAVE THESE INSTRUCTIONS.

Depth gauge

1. Depth gauge 2. Clamp screw

The depth gauge is convenient for drilling holes of uniform depth. Insert the depth gauge into the hole in the grip base. Adjust the depth gauge to the desired depth and then tighten the clamp screw to secure the depth gauge.

NOTE: The depth gauge cannot be used at the position where the depth gauge strikes against the tool body.

OPERATION

Hammer drilling operation

Set the change lever to the T symbol.

Position the bit at the desired location for the hole, then pull the switch trigger. Do not force the tool. Light pressure gives best results. Keep the tool in position and prevent it from slipping away from the hole.

Do not apply more pressure when the hole becomes clogged with chips or particles. Instead, run the tool at an idle, then remove the bit partially from the hole. By repeating this several times, the hole will be cleaned out and normal drilling may be resumed.

CAUTION: There is a tremendous and sudden twisting force exerted on the tool/bit at the time of hole break-through, when the hole becomes clogged with chips and particles, or when striking reinforcing rods embedded in the concrete. Always use the side grip (auxiliary handle) and firmly hold the tool by both side grip and switch handle during operations. Failure to do so may result in the loss of control of the tool and potentially severe injury.

Blow-out bulb (optional accessory)

1. Blow-out bulb

After drilling the hole, use the blow-out bulb to clean the dust out of the hole.

Chipping/Scaling/Demolition

Set the change lever to the T symbol.

Hold the tool firmly with both hands. Turn the tool on and apply slight pressure on the tool so that the tool will not bounce around, uncontrolled. Pressing very hard on the tool will not increase the efficiency.

MAINTENANCE

CAUTION: Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.

Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.

Lubrication

CAUTION: This servicing should be performed by Makita Authorized or Factory Service Centers only.

This tool requires no hourly or daily lubrication because it has a grease-packed lubrication system. It should be relubricated regularly. Send the complete tool to Makita Authorized or Factory Service Center for this lubrication service.
