WHEEL GUARD
The machine is equipped with a wheel guard consisting
of a stationary (2) and mobile (10) part.
The wheel guard (2) and the mobile cover (10) must be
always mounted on the machine.
ROTATING THE MOBILE GUARD COVER AND
REPLACING THE RUBBER SEAL
Rotate the mobile guard cover (10) in the direction indi-
cated with an arrow on the cover (Fig. 6). Prior to rotating,
pull the mobile guard cover slightly forward. Rotate the
mobile guard cover at 90º so that it will touch the sta-
tionary wheel guard (2) (Fig. 7). This allows uncovering
part of the operating tool in order to process corners and
hard to access surfaces.
The rubber seal (9) ensures decreasing the dust emis-
sion in the environment to the utmost. It wears out along
with the wheel. When replacing the wheel if necessary
replace the rubber seal as well. Remove the old rubber
seal by pulling it out. Mount the new rubber seal taking
care that the folded area is inserted in the guard groove
until stop.
ASSEMBLY, REPLACING AND ADJUSTING
THE CUP WHEEL POSITION
Make sure the cup wheel diameter and thickness do not
exceed the values stated in the technical specifications.
The maximum admissible speed indicated on the wheel
must not be less than the machine no load speed.
Fix the spindle (1) by pressing the lock button (8) on the
gear case.
WARNING: Never press button (8) while the
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.
AUXILIARY HANDLE
The auxiliary handle (11) is fastened to the gear case
through two screws (13). Always use the auxiliary han-
dle and hold the machine firmly with both hands. (Fig. 1)
DUST EXTRACTION
This power tool must only be used with a dust extraction
system. In addition, always wear approved dust mask.
Always make sure the vacuum cleaner that you use is
designed for extraction of masonry dust. Connect the
vacuum cleaner to the dust extraction port on the wheel
guard.
We recommend using industrial vacuum cleaner with
minimum technical parameters: airflow 60 l/s and cre-
ated sub-pressure (vacuum) 180 mbar.
