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 switch trigger actuates properly and returns to the "OFF" position when released.

To start the tool, simply pull the switch trigger. Release the switch trigger to stop.

For continuous operation, pull the switch trigger and then push in the lock button.

To stop the tool from the locked position, pull the switch trigger fully, then release it.

Speed adjusting dial

For BO4900V only

CAUTION:

• If the tool is operated continuously at low speeds, the motor will get overloaded and heated up.
• The speed adjusting dial can be turned only as far as 5 and back to 1. Do not force it past 5 or 1, or the speed adjusting function may no longer work.

The tool speed can be infinitely adjusted between 4,000 and 11,000 orbits per minute by turning the speed adjusting dial, which is marked 1 to 5. Higher speed is obtained when the dial is turned in the direction of number 5, lower speed is obtained when it is turned in the direction of number 1. Adjust the desired tool speed for the kind of work.

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

For conventional type of abrasive paper with prepunched holes (standard equipment):

Turn the clamp lever counterclockwise. Insert the paper end into the clamper, aligning the holes in the paper with those in the pad. Then return the clamp lever to the original position to secure the paper. Repeat the same process for the other end of the tool, maintaining the proper paper tension. (Fig. 2)

For conventional type of abrasive paper without prepunched holes (accessory):

Turn the clamp lever counterclockwise. Insert the paper end into the clamper, aligning the paper edges even and parallel with the sides of the base. Then return the clamp lever to the original position to secure the paper. Repeat the same process for the other end of the tool, maintaining the proper paper tension.

Place the punch plate (optional accessory) over the paper so that the guide of the punch plate is flush with the sides of the pad. Then press the punch plate to make holes in the paper. (Fig. 3)

For hook-and-loop type of abrasive paper with prepunched holes (accessory):

Remove all dirt or foreign matter from the pad. Attach the paper to the pad, aligning the holes in the paper with those in the pad. (Fig. 4)

CAUTION:

• Never use pressure-sensitive abrasive paper.

For BO4901 only

NOTE:

• To use the hook-and-loop type of abrasive paper, first replace the pad. Remove the pad for the conventional type of abrasive paper from the tool with a screwdriver. (Fig.5)

Install the pad for the hook-and-loop type of abrasive paper (optional accessory) on the tool. Tighten the screws firmly to secure the pad.

Installing paper dust bag (accessory)

For BO4900, BO4900V only

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.6)

Then press the upper part of the front fixing cardboard in arrow direction to hook it onto the claws. (Fig. 7)

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. 8 & 9)

Installing dust bag (accessory) (Fig. 10)

For BO4900, BO4900V only

Install the dust bag on the tool so that the arrow with "UP" indicated on the dust nozzle points upward.

Emptying dust bag

When the dust bag is about half full, switch off and unplug the tool. Hold the tool and remove the dust bag from the dust nozzle while pressing the push button. (Fig. 11 & 12)

After emptying the dust bag, insert the hook on the dust nozzle into the rectangular hole on one side of the dust bag frame until it clicks into place on the push button. (Fig. 13)

Connecting to vacuum cleaner (Fig. 14)

When you wish to perform cleaner operation, connect a vacuum cleaner to your tool. Connect a hose of vacuum cleaner to the dust nozzle.

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 and/or shorten tool life.
• The front grip is a screwed type one. Always be sure that the front grip is tightened securely before operation.

Turn the tool on and wait until it attains full speed. Then gently place the tool on the workpiece surface. Keep the base flush with the workpiece and apply a light pressure on the tool.

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.

ENG905-1

Noise

The typical A-weighted noise level determined according to EN62841:

Sound pressure level (L_pA) : 71 dB (A)

Uncertainty (K): 3 dB (A)

The noise level under working may exceed 80dB (A).

ENG907-1

NOTE:

• The declared noise emission value(s) has been measured in accordance with a standard test method and may be used for comparing one tool with another.
• The declared noise emission value(s) may also be used in a preliminary assessment of exposure.

WARNING:

• Wear ear protection.

• The noise emission during actual use of the power tool can differ from the declared value(s) depending on the ways in which the tool is used especially what kind of workpiece is processed.

• Be sure to identify safety measures to protect the operator that are based on an estimation of exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time).

Vibration

The vibration total value (tri-axial vector sum) determined according to EN62841:

Model BO4900, BO4900V

Work mode: sanding metal plate

Vibration emission (_h) .. 2.5m / s^2 or less

Uncertainty (K): 1.5m / s^2

Model BO4901

Work mode: sanding metal plate

Vibration emission (a_h) .. 4.0~m / s^2

Uncertainty (K): 1.5m / s^2

ENG901-2

NOTE:

• The declared vibration total value(s) has been measured in accordance with a standard test method and may be used for comparing one tool with another.
• The declared vibration total value(s) may also be used in a preliminary assessment of exposure.

WARNING:

• The vibration emission during actual use of the power tool can differ from the declared value(s) depending on the ways in which the tool is used especially what kind of workpiece is processed.
