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 EN62841:
Sound pressure level (L pA ): 72 dB (A)
Uncertainty (K): 3 dB (A)
The noise level under working may exceed 80 dB (A).
Wear ear protection

Vibration
The vibration total value (tri-axial vector sum) determined according to EN62841:
Work mode: sanding metal plate
Vibration emission (a): 3.5 m/s 2 h
Uncertainty (K): 1.5 m/s 2

NOTE: 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.

NOTE: The declared vibration emission value may also be used in a preliminary assessment of exposure.


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).

FUNCTIONAL DESCRIPTION


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

Switch action

Speed adjusting dial

For BO3711 only
FUNCTIONAL DESCRIPTION - Speed adjusting dial

  1. Speed adjusting dial

  • 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.
