14. Rim speed of the wet sanding disc
The maximum rim speed of the wet sanding disc is:
Ø 200 = 1.37 m/s
Calculation: Rim speed
m/s = d x 3.14 x n
60 x 1000
d = diameter of the sanding disc in mm
n = motor rotation speed per minute
Example:
m/s = 200 x 3,14 x n
60 x 1000
= 1.37 m/s
15. Caution when handling water
Switch off the sander, disconnect the mains plug. When you fill the water tank, spill
as little water as possible and do not let any water run over the motor. Wipe away
any spilled water. The maximum water tank capacity amounts to approx. 0.5 l.
