Symbols

The following show the symbols used for the equipment. Be sure that you understand their meaning before use.
Read the instruction manual.
DOUBLE INSULATION
Only for EU countries Do not dispose of electric equipment together with household waste material! In observance of the European Directive, on Waste Electric and Electronic Equipment and its implementation in accordance with national law, electric equipment that have reached the end of their life must be collected separately and returned to an environmentally compatible recycling facility.

Intended use

The tool is intended for the sanding of large surface of wood, plastic and metal materials as well as painted surfaces.

Power supply

The tool should be connected only to a power supply of the same voltage as indicated on the nameplate, and can only be operated on single-phase AC supply. They are double-insulated in accordance with European Standard and can, therefore, also be used from sockets without earth wire.

General power tool safety warnings

WARNING: Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

Work area safety

Keep work area clean and well lit. Cluttered or 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 which 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 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 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. Use of a cord suitable for outdoor use reduces the risk of electric shock.
If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.
Use of power supply via an RCD with a rated residual current of 30 mA or less is always recommended.
Power tools can produce electromagnetic fields (EMF) that are not harmful to the user. However, users of pacemakers and other similar medical devices should contact the maker of their device and/or doctor for advice before operating this power tool.
Do not touch the power plug with wet hands.
If the cord is damaged, have it replaced by the manufacturer or his agent in order to avoid a safety hazard.

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 personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing 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 and clothing away from moving parts. Loose clothes, jewellery 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. Use of dust collection can reduce dust-related hazards.
Do not let familiarity gained from the frequent use of tools make you complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.
Always wear protective goggles to protect your eyes from injury when using power tools. The goggles must comply with ANSI Z87.1 in the USA, EN 166 in Europe, or AS/NZS 1336 in Australia/New Zealand. In Australia/New Zealand, it is legally required to wear a face shield to protect your face, too. It is an employer’s responsibility to enforce the use of appropriate safety protective equipment by the tool operators and by other persons in the immediate working area.

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 remove the battery pack, if detachable, 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 and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s 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 and tool bits etc. in accordance with these instructions, 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.
Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.
When using the tool, do not wear cloth work gloves which may be entangled. The entanglement of cloth work gloves in the moving parts may result in personal injury.

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 instruction for lubricating and changing accessories.

FUNCTIONAL DESCRIPTION

CAUTION:

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

Switch action (Fig. 1)

CAUTION:

Before plugging in the tool, always check to see that the tool is switched off.
To start the tool, press the “I” side of the switch. To stop the tool, press the “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
Open the paper clamp by raising on the lever to release from the locking port and then Insert the paper end into the clamping part, aligning the paper edges even and parallel with the sides of the base. (Bending the paper beforehand makes attachment easier).
Once the paper is in place, return the lever to its original position. (Fig. 2 & Fig. 3)
Repeat the same process for the other end of the base, maintaining the proper paper tension.
After inserting the paper, make sure the clamping part holds it securely. Otherwise, the paper will be loose and subject to slippage, resulting in uneven sanding operation.
When using the dust bag, make holes in the abrasive paper using the punch plate as follows (Fig. 4):

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.

Model BO4555 only (Fig. 5)

NOTE:

Use Makita hook-and-loop sandpaper with this sander.

Set the tool upside down so that the pad is on top.
Position the sandpaper to fit the shape of the base. Be sure to align the holes on the sandpaper with the holes on the pad (the dust will be sucked into these holes; it is, therefore, important to leave them open).
Press the paper firmly over the pad.

To remove the sandpaper:

Set the tool upside down so that the sandpaper is on top.
Grasping one corner of the sandpaper, peel it from the pad.

NOTE:

If the sandpaper is in good condition, save it for further use.

Dust bag (accessory) (Fig. 6)

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 pimplelike 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.

Installing paper dust bag (accessory)

Place the paper dust bag on the paper dust bag holder with its front side upward. Insert the front fixing cardboard of the paper dust bag into the groove of the paper dust bag holder. (Fig. 7)
Then press the upper part of the front fixing the cardboard in the arrow direction to hook it onto the claws. (Fig. 8)
Insert the notch of the paper dust bag into the guide of the paper dust bag holder. Then install the paper dust bag holder set on the tool. (Fig. 9 & Fig. 10)

Installing paper filter bag

Make sure that the logo on the cardboard lip and the logo on the dust box is on the same side, then install the paper filter bag by fitting the cardboard lip in the groove of each holding tab. (Fig. 11)
Make sure that the logo on the cardboard lip and the logo on the dust nozzle is on the same side, then install the dust nozzle on the dust box. (Fig. 12)
Removing dust box and paper filter bag.
Remove the dust nozzle by pushing the two latches. (Fig. 13)
Remove the paper filter bag first by pinching the logo side of its cardboard lip, then by pulling the cardboard lip downwards to move it out of the holding tab of the dust box. (Fig. 14)

OPERATION

Sanding operation (Fig. 15)

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, and/ 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. A finishing sander is generally used to remove only a small amount of material at a time. Since the quality of the surface is more important than the amount of stock removed, do not bear down on the tool. Keep the base flush with the workpiece at all times.

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.
To maintain product SAFETY and RELIABILITY, repairs, carbon brush inspection and replacement, any other maintenance or adjustment should be performed by Makita Authorized Service Centers, always using Makita replacement parts.
