GENERAL SAFETY RULES

WARNING: Read all instructions. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury. The term “power tool” in all of the warnings listed below refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

Work area safety

Keep the work area clean and well-lit. Cluttered and dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks that may ignite the dust or fumes.
Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
Electrical safety
Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce the risk of electric shock.
Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep the cord away from heat, oil, sharp edges, or moving parts. Damaged or entangled cords increase the risk of electric shock.
When operating a power tool outdoors, use an extension cord suitable for outdoor use. The use of a cord suitable for outdoor use reduces the risk of electric shock.
Personal safety
Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.
Use safety equipment. Always wear eye protection. Safety equipment such as dust masks, non-skid safety shoes, hard hats, or hearing protection used for appropriate conditions will reduce personal injuries.
Avoid accidental starting. Ensure the switch is in the off-position before plugging in. Carrying power tools with your finger on the switch or plugging in power tools that have the switch on invites accidents.
Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. The use of these devices can reduce dust-related hazards.
Power tool use and care
Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tool operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
Use the power tool, accessories tool bits, etc. under these instructions and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
Service
Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
Follow instructions for lubricating and changing accessories.
Keep handles dry, clean, and free from oil and grease.

SPECIFIC SAFETY RULES

DO NOT let comfort or familiarity with the product (gained from repeated use) replace strict adherence to sander safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.

Hold power tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.
Always use safety glasses or goggles. Ordinary eyes or sunglasses are NOT safety glasses.
Hold the tool firmly.
Do not leave the tool running. Operate the tool only when hand-held.
This tool has not been waterproofed, so do not use water on the workpiece surface.
Ventilate your work area adequately when you perform sanding operations.
Some materials contain chemicals that may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.
Use of this tool to sand some products, paints, and wood could expose users to dust containing hazardous substances. Use appropriate respiratory protection.
Be sure that there are no cracks or breakage on the pad before use. Cracks or breakages may cause personal injury.

SAVE THESE INSTRUCTIONS.

WARNING: MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury.

SYMBOLS

FUNCTIONAL DESCRIPTION

CAUTION: Always be sure that the tool is switched off and unplugged before adjusting or checking the function of the tool.

Switch action

CAUTION:

Before plugging in the tool, always check to see that the tool is switched off.
The switch can be locked in the “ON” position for ease of operator comfort during extended use. Apply caution when locking the tool in the “ON” position and maintain a firm grasp on the tool.

To start the tool, press the “ON ( I )” side of the switch. To stop the tool, press the “OFF (O)” side of the switch.

ASSEMBLY

CAUTION: Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.

Installing or removing abrasive paper

To install the abrasive paper, operate the clamp lever to open the paper clamp. Insert the paper end into the clamp. Center the paper and align the edges parallel to the pad, then lower the clamp lever to secure the paper.(Prebending paper makes attachment easier.)
Repeat the same process for the other end of the base, maintaining the proper paper tension.
After inserting the paper, make sure the teeth of the clamp hold it securely. Otherwise, the paper will be loose and subject to slippage, resulting in uneven sanding operation.

Punch plate

When using the dust bag, make holes in the abrasive paper using the punch plate as follows:

Set the tool upside down.
Place the punch plate over the abrasive paper so that the bent sides of the punch plate are flush with the paper edges.
Press the punch plate to make holes in the abrasive paper.

CAUTION: Be sure to remove the punch plate before operating the tool.

Dust bag

The use of the dust bag makes sanding operations clean and dust collection easy. To attach the dust bag, fit the bag’s entry port onto the dust spout on the tool. Make sure that the hole in the bag’s entry port is just over the pimple-like protrusion on the dust spout.
For the best results, empty the dust bag when it becomes approximately half full, tapping it lightly to remove as much dust as possible.

OPERATION

Sanding operation

CAUTION:

Never run the tool without the abrasive paper. You may seriously damage the pad.
Never force the tool. Excessive pressure may decrease the sanding efficiency, damage the abrasive paper, or shorten tool life.

Hold the tool firmly. Turn the tool on and wait until it attains full speed. Then gently place the tool on the workpiece surface. Keep the pad flush with the workpiece and apply slight pressure on the tool.

MAINTENANCE

CAUTION: Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.
To maintain product SAFETY and RELIABILITY, repairs, carbon brush inspection and replacement, and any other maintenance or adjustment should be performed by Makita Authorized or Factory Service Centers, always using Makita replacement parts.

WARNING

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

lead from lead-based paints,
crystalline silica from bricks and cement and other masonry products, and
arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.
