■
OPERATING
The key to efficient operating is controlling the pressure and
surface contact between the disc and work piece. The speed
of rotation can be changed by adjusting the speed control
switch to the most suitable for the job. (See Table 1)The
general rules for operating speed apply:- grinding & sanding -
high speed; polishing - low speed.
Flat surfaces are ground at an acute angle, usually 10 to 20
degrees with the workpiece. Too great an angle causes a
concentration of pressure on a small area which may gouge or
burn work surface. Allow the disc to reach full speed before
starting to grind, sand or polish.
■
MAINTAINANCE
After use, check your tool to keep it in top condition.
• Clean out accumulated dust.
• When carbon brushes are worn to the standard line, they
must be replaced.
