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.

Noise
The typical A-weighted noise level determined according to EN60745:
Sound pressure level (LpA) : 81 dB(A) Sound power level (LWA) : 92 dB(A) Uncertainty (K) : 3 dB(A)

Wear ear protection

Vibration
The vibration total value (tri-axial vector sum) determined according to EN60745:
Work mode : sanding metal plate
Vibration emission (ah) : 3.5 m/s2
Uncertainty (K) : 1.5 m/s2

• 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 has been measured in accordance with the standard test method and may be used for comparing one tool with another.

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).

Speed adjusting dial

For BO5041 only
Fig.2
The tool speed can be infinitely adjusted between 4,000 and 12,000 orbit per minute by turning the adjusting dial. 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.
Refer to the figure for the relationship between the number settings on the adjusting dial and the kind of work.

• A range: For polishing
• B range: For finish sanding
• C range: For regular sanding

NOTE:

• The figure shows standard applications. They may differ under certain conditions.

Sanding operation

Fig.19

CAUTION:

• Never run the tool without the abrasive disc. You may seriously damage the pad.
• Never force the tool. Excessive pressure may decrease the sanding efficiency, damage the abrasive disc or shorten tool life.
• Using the tool with the pad edge contacting the workpiece may damage the pad.

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.

CAUTION:
The sanding pad rotates clockwise during the loaded operation, but it may rotate counterclockwise during the no-load operation.

Polishing operation ”

For BO5041 only

CAUTION:

• Use only a Makita genuine sponge pad, felt pad or wool pad (optional accessories).
• Always operate the tool at low speed to prevent work surfaces from heating abnormally.
• Never force the tool. Excessive pressure may decrease the polishing efficiency and cause motor overload, resulting in tool malfunction.

1. Applying wax
   Fig.20
   Use an optional sponge pad. Apply wax to the sponge pad or work surface. Run the tool at low speed to smooth out wax.
   NOTE:

   • First, wax a not conspicuous portion of the work surface to make sure that the tool will not scratch the surface or result in uneven waxing.
   • Always run the tool at low speed. Running it at high speed may cause the wax to spatter.

2. Removing wax Fig.21
   Use an optional felt pad. Run the tool at low speed to remove wax.

3. Polishing
   Fig.22
   Use an optional wool pad. Run the tool at low speed and apply the wool pad gently to the work surface.
