Check the recovery tank is empty (if necessary, empty it).
3.
remove the tube from the sleeve on the squeegee

5.
remove the other end of the tube (2) from the rubber-holder connector (3) of the recovery tank
6.
wash the inside of the tube with a jet of water (from the tank side)
7.
reassemble the tube
2.
CHECKING THE WHEEL BRAKE
Every week, check the distance between the work brake pads and the wheels. If necessary, adjust them
by means of the nuts, so they are at a distance of 3mm when homed.

CLEANING THE SOLUTION TANK
1.
Engage the parking brake and turn the key switch to position "0 "

ATTENTION: These operations must be carried out using gloves to protect
against contact with dangerous solutions
4. REPLACING THE BRUSH HEAD SPLASH GUARDS
To ensure the water is collected efficiently while the machine is working, you should periodically check the
state of wear and tear of the side splash guards. When you need to replace them, proceed as follows:
1.
with the base up, loosen the screws (1) that fix the blocking blade of the splash guard rubber
2.
unthread the splash guard rubber and rotate it by 180° in order to replace the worn part with a
new one. If the splash guards are worn on both sides, replace them with new rubbers (contact the
COMAC assistance centre)
3.
reassemble everything, carrying out the above-mentioned operations in the reverse order
ATTENTION: this operation must be carried out using gloves to protect against
contact with dangerous solutions
5. REPLACING THE SQUEEGEE RUBBERS
Suction will be poor and the machine will not dry perfectly if the front squeegee rubber is worn. Proceed as
follows to replace:
1.
remove the tube (1) from the squeegee
2.
remove the squeegee, pushing the plate (2) to the left in order to release the squeegee small column
from its seat
