the machine!

screw fixing flange 5 by a lock nut wrench. Place
the new wheel on the support flange 3 and screw
down the fixing flange 5 with its flat side facing
the wheel using the lock nut wrench. After re-
placing the wheel, operate the machine with the
new wheel in no load mode for one minute. Vi-
brating or otherwise improperly rotating wheels
must be repla ced immediately and discarded.
When replacing the wheel, change the rubber
seal as well.
REPLACING THE RUBBER SEAL
The rubber seal 10 provides for decreasing
to the utmost of the dust emitted in the envi-
ronment. It wears out along with the wheel.
When replacing the wheel, change the rubber
seal as well. Loosen the screw in bracket 11
and remove the old rubber seal. Place the new
seal, taking care the edge of the wheel guard 2
will enter the provided in the seal groove. Place
back bracket 11 and fasten it.
AUxILIARY HANDLE
The auxiliary handle 6 is fastened to the gear
case by two screws. Always use the auxiliary
handle and hold the machine firmly with both
hands.
DUST ExTRACTION
The machine can be operated only with dust ex-
traction. Wear dust-proof mask. We re commend
the use of a vacuum cleaner for industrial pur-
poses, with specifications: minimum airflow rate
60 l/s and minimum created subpressure (vacu-
um) 180 mbar. Connect the vacuum cleaner to
the dust extraction tube of the wheel guard.
