REPLACING BACKING PAD.

brake seal to hold the spindle nut (8). Turn the backing 

pad counterclockwise to remove it (9). Fit and tighten 

the new backing pad with washers. Remove the pad

MAINTENANCE.

The sander has been designed for a long working 

life with minimum maintenance. Optimum use 

depends on correct care of the sander and regular 

cleaning. To prevent accidents, always unplug the 

sander from the power source before cleaning or 

performing any maintenance. The sander may be 

cleaned effectively using compressed air after each 

use. If compressed air is not available, use a brush 

to remove dust from the sander. Motor ventilation 

vents and switch levers must be dept clean and free 

of foreign matter. Do not attempt to clean by inserting 

pointed  objects  through  openings.  Cetain  cleaning 

agents and solvents damage plastic parts, among 

them are gasoline, carbon tetrachloride, chlorinated 

cleaning solvents, ammonia and household cleaners 

containing ammonia. Do not use any of these to clean 

the sander.
