spindle is still rotating!
With this button depressed turn the spindle till its pro-
nounced going deeper. Unscrew lock nut (6) by the lock
nut wrench (12).
In view of the cup wheel wear and in order to achieve
optimum dust extraction a possibility is provided to adjust
the cup wheel position to the wear of the cup wheel.
When placing a new cup wheel arrange the components
on the spindle in the following order: base support wash-
er (3); cup wheel (4); lock nut (6) with its flat end towards
the cup wheel as shown on Fig. 4.
WARNING: Placing the lock nut (6) with its
convex end towards the cup wheel shall make tighten-
ing the cup wheel impossible.
In case the cup wheel is half worn out or more, arrange
the components on the spindle in the following order: flat
support washer (5); cup wheel (4); lock nut (6) with its
convex end towards the cup wheel as shown on Fig. 5.
WARNING: Placing the lock nut with its flat
end towards the cup wheel shall obstruct centring the
cup wheel thus causing excessive vibration and may
result in personal injury.
WARNING: After replacing the wheel, operate
the machine with the new wheel at no load mode for
minimum 30 seconds. Vibrating or otherwise improp-
erly rotating wheels must be replaced immediately and
discarded.
In case of changing the cup wheel position adjust it or
replace the brush shield if necessary.
ADJUSTING (REPLACING) THE BRUSH
SHIELD POSITION
The brush shield (9) ensures decreasing the dust emis-
sion in the environment to the utmost. The brush shield
wears out along with the wheel. When replacing the
wheel if necessary change the brush as well. Loosen the
screw in bracket (10) and remove the old brush. Place
the new brush, taking care that the edge of the wheel
guard (2) contacts the brush rib. Place the bracket (10)
back and fasten it.
AUXILIARY HANDLE
The auxiliary handle (11) is fastened to the gear case
through two screws. Always use the auxiliary handle
and hold the machine firmly with both hands. (Fig. 1)
