Intended use

The tool is intended for the sanding of large surfaces 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 a single-phase AC supply. They are double-insulated and can, therefore, also be used from sockets without earth wire.

Noise

The typical A-weighted noise level is determined according to EN60745:
Sound pressure level (LpA): 82 dB(A)
Sound power level (LWA): 93 dB (A)
Uncertainty (K): 3 dB(A)
WARNING: Wear ear protection.

Vibration

The vibration total value (tri-axial vector sum) determined according to EN60745:
Work mode: sanding metal plate
Vibration emission(ah): 5.0 m/s²
Uncertainty (K) : 1.5 m/s²
Work mode: polishing
Vibration emission (ah, AG) : 3.0 m/s²
Uncertainty (K) : 1.5 m/s²
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.

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.
WARNING: Be sure to identify safety measures to protect the operator that is 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

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

Switch action

CAUTION: Before plugging in the tool, always check to see that the slide switch actuates properly and returns to the “OFF” position when the rear of the slide switch is depressed.
CAUTION: When locking the tool in the “ON” position apply caution and maintain a firm grasp on the tool.
To start the tool, slide the slide switch toward the “I (ON)” position. For continuous operation, press the front of the slide switch to lock it.
►Fig.1: 1. Slide switch
To stop the tool, press the rear of the slide switch, then slide it toward the “O (OFF)” position.
►Fig.2: 1. Slide switch

Speed adjusting dial

►Fig.3: 1. Speed adjusting dial
The rotating speed can be changed by turning the speed and adjusting dial to a given number setting from 1 to 5. Higher speed is obtained when the dial is turned in the direction of number 5. And lower speed is obtained when it is turned in the direction of number 1.
Refer to the table for the relationship between the number settings on the dial and the approximate rotating speed.

Number| Orbits per min.| Pad rotating speed per minute in random orbit with forced rotation mode
---|---|---
1| 1,600| 140
2| 2,900| 260
3| 4,200| 370
4| 5,500| 490
5| 6,800| 600

NOTICE: If the tool is operated continuously at low speeds for a long time, the motor will get overloaded, resulting in tool malfunction.
NOTICE: 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.

Electronic function

The tools equipped with electronic functions are easy to operate because of the following features.
Constant speed control
Possible to get a fine finish, because the rotating speed is kept constant even under the loaded condition.
Soft start feature
Soft start because of suppressed starting shock.

Selecting the action mode

Use the change knob to change the rotation mode.
NOTICE: Always turn the knob fully. If the knob is in the middle position, you can not turn on the tool.
NOTE: You can not change the active mode when the tool is switched on.
Random orbit with forced rotation mode
