Noise And Vibration - 3M PN 64392 Manual Del Usuario

TEST RUN
Start the tool and check that there are no unusual vibrations and that the polishing pad is in good condition.
Warning: If there is a problem switch-off the tool immediately and eliminate the cause.
SPEED REGULATION
The speed can be adjusted by rotating the wheel (3) located on the top of the tool. The choice of speed depends on the characteristics of the polishing pad and
the material to be worked.
DISASSEMBLY OF THE BUFFER PAD
- Hold the spindle still with the 17 mm spanner or use the spindle lock (14);
- disassemble the buff er pad with the pin spanner. The use of any other tool is strictly prohibited
USE OF ACCESSORIES
- Polishing pads and Hookit™ Sponges with a maximum diameter of 200 mm.
- All maintenance operations are carried out with the power supply disconnected.
- At the end of each work session, or when required, remove any dust from the body of the tool using a vacuum system, paying particular attention to the
motor ventilation slots.
No other maintenance operations must be undertaken by the user.
Maintenance and cleaning of the inner parts, like brushes, ball bearings, gears etc. or others, must be carried out only by an authorised customer-service workshop.
ELECTRIC SAFETY - LOW VOLTAGE
The tests have been carried out in accordance with the standard:
EN 60745-1 Safety of hand-held electric motor operated tools
EN 60745-2-3 Particular requirements for grinders, polishers and disc sanders.
RADIO SUPPRESSION
The tools are suppressed in accordance for the prevention and elimination of radio disturbances measured in accordance with standard:
EN55014-1+EN55014-2; EN61000-3-2+EN61000-3-3.
NOISE LEVEL
The noise level, produced by the machine in normal working conditions at the work station was measured according to regulation EN ISO 3744.
Surface Sound Pressure Level
Sound Power Level
And according the regulation + UNI EN ISO 11202.
Surface sound pressure level
Sound Power Level
Notice: The values of the uncertainty Kpa, KpC, peak and KWA are obtained from the corresponding basic standards ISO 11202 and ISO 3744.
Warning: Wear suitable hearing protection! (see warnings).
MEAN ACCELERATION VALUE
The mean quadratic acceleration value was measured in accordance with standard UNI EN 28662 + UNI EN ISO 5349 + EN 60745- 1:
Front handle A=2,21 m/sec
Rear handle A=2,72 m/sec
