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 "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

For conventional type of abrasive paper with prepunched holes (standard equipment): (Fig. 2)

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. 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 hold it securely. Otherwise the paper will be loose and subject to slippage, resulting in uneven sanding operation. To remove the paper, release the clamper as stated above.

For conventional type of abrasive paper without prepunched holes (available on the market): (Fig. 3)

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. 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 hold it securely. Otherwise the paper will be loose and subject to slippage, resulting in uneven sanding operation. Place the punch plate (optional accessory) over the paper so that the guide of the punch plate is flush with the sides of the base. Then press the punch plate to make holes in the paper.

To remove the paper, release the clamper as stated above.

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

CAUTION:

• Always use hook-and-loop type of abrasive papers. Never use pressure-sensitive abrasive paper. (Fig. 4) Remove the pad for the conventional type of abrasive paper from the tool with a screwdriver. 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. (Fig. 5)

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. 6)

CAUTION:

• When removing the pad, O ring may come out of the tool. When this occurs, return the O ring to the original position and then install the pad.

Dust bag (optional accessory) (Fig. 7)

Attach the dust bag onto the dust spout. The dust spout is tapered. When attaching the dust bag, push it onto the

dust spout firmly as far as it will go to prevent it from coming off during operation.

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 filter (optional accessory) (Fig. 8)

Make sure that the logo on the cardboard lip and the logo on the dust box are on the same side, then install the filter by fitting the cardboard lip in the groove of each holding tab. (Fig. 9)

Make sure that the logo on the cardboard lip and the logo on the dust nozzle are on the same side, then install the dust nozzle on the dust box. Removing dust box and filter. (Fig. 10)

Remove the dust nozzle by pushing the two latches. (Fig. 11)

Remove the filter 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.

OPERATION

Sanding operation (Fig. 12)

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.

Noise

ENG905-1

The typical A-weighted noise level determined according to EN60745:

Sound pressure level (L_pA) : 75 dB (A)

Uncertainty (K): 3 dB (A)

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

Wear ear protection.

Vibration

ENG900-1

The vibration total value (tri-axial vector sum) determined according to EN60745:

Work mode: sanding metal plate

Vibration emission (a_h) .. 5.0~m / s^2

Uncertainty (K): 1.5m / s^2

ENG901-1

• The declared vibration emission value has been measured in accordance with the standard test method and may be used for comparing one tool with another.
• The declared vibration emission value 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 emission value depending on the ways in which the tool is used.
• 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).
