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

1. Lock button
2. Switch trigger

• 
  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 BO3711 only

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.

ASSEMBLY

• 
  Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.

Installing or removing abrasive paper

2. Abrasive paper without prepunched holes

Press down the clamp lever 1 and with the clamp lever pressed down slide it toward the tool 2 and the clamper will be released.
Insert the paper end between a clamper and the pad aligning the paper edges even and parallel with the sides of the base. Then return the clamp lever to the original position to secure it.
Release the other clamp lever by repeating the same procedure. While pulling abrasive paper to maintain the proper tension, insert and secure the other end of abrasive paper between another clamper and the pad and return the paper clamp lever to the original position.
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 pre-punched holes (optional accessory):

• 
  Always use hook-and-loop type of abrasive papers. Never use pressure-sensitive abrasive paper.
