CAUTION!Risk of equipment damage
• Turn off the vacuum cleaner if dust escapes
from it.
• Do not use the vacuum cleaner if there is re-
stricted or no airflow. The fan motor can be-
come overheated. Prevent overheating by
ensuring that a flow of air passes the fan
• Motors rotating in the wrong direction can
cause overheating.
5.1Vacuuming
NOTE!
• The starting handle makes Y/D start possible
in both rotational directions. The motor’s dir-
ection of rotation must match the arrow on
the fan housing, see Section4.2Impeller ro-
tation.
• For best results, adjust the gulper head de-
pending on the type and weight of material
to be vacuumed, see Figure9.
• During start, the vacuum cleaner may move
in a sideways direction, so be sure to always
hold onto the vacuum cleaner when starting.

ator is full, suction power is reduced. Clean
the filter and empty the pre-separator. See
Chapter6Maintenance.
