Maintenance - Sparky PROFESSIONAL MBG 150 Originalbetriebsanleitung

▪ Check and adjust if necessary the tool rests po-
sition so that the distance between each one
and the wheel does not exceed 1.6 mm (Fig.11).
Adjust regularly the distance between the
wheel and the tool rest as the diameter of the
wheel decreases with use. This will ensure the
proper angle for sharpening and hence - high
efficiency. The tool rests shall be used always
in horizontal position.
▪ When you switch the machine on let it operate
at no load until the motor gains full speed.
WARNING: Never use accessories or at-
tachments differing from those recommended in
this manual.
WARNING: Never sharpen or grind parts
made of aluminium, brass, or copper.
▪ While grinding, rest the machined piece against
the wheel front surface, do not grind on the
wheel flat side. Overloading the wheel side
surfaces is dangerous and must not be at-
tempted.
WARNING: In normal brushing opera-
tions, the material being removed will fly off the
brush with considerable force along with brush
filaments which break off due to fatigue. Do not
operate the bench grinder unless the eye shields
are dropped down or without goggles.
▪ Avoid excessive pressure when using the brush.
Excessive pressure causes over-bending of
the filaments, filament breakage, and reduced
brush life.
WARNING: Never exceed the recom-
mended Maximum Safe Free Speed R.P.M.
(MSFS) rating of the brush.
▪ Do not continue to use worn, torn or heavily
clogged sanding belts.
▪ Do not touch the moving sanding belt.
