WARNING: DO NOT EXCEED 2750 RPM WITHOUT FIRST CONSULTING THE
FACTORY.
CAUTION
: Street sweeping requires a great deal of concentration by the operator to
avoid road hazards such as parked cars, pedestrians, chuckholes, etc. Judge
the street conditions and operate sweeper at a safe speed regardless of how
heavy or light the curb debris is.
Service
Periodic servicing of the blower should be performed on the following items:
1. Blower Service
– For longer blower life, clean the dust separator daily. (Refer to the
Hopper Section of this manual)
2. Blower Bearings
– The bearings are pressed into an aluminum hub which is bolted to
the blower housing cover. These bearings are sealed and no greasing is required.
The operator should be made aware of their location and should listen for any un-
usual noise coming from the blower housing indicating a bearing problem. The
sweeper should be serviced IMMEDIATELY when a bearing problem is detected.
3. Blower
– Wear on the blower is normal; however, the blower should be replaced
when sweeping performance is noticeably reduced. An out-of-balance blower due to
caked-on debris or wear can destroy the bearings over time as well. If the blower
housing is severely vibrating when the blower is on, the blower is not balanced and
should be removed IMMEDIATELY.
4. Blower Housing Liner / Blower Lip
– A rubber bolt-in wear liner is used to protect the
metal scroll in the blower housing. The liner should be inspected every 500 hours of
sweeper operation and replaced if expanded metal is evident. The blower lip should
be inspected along with the blower housing liner. If worn, it has two usable sides and
can be reversed. If both sides have been worn, then replace it.
NOTE: A thorough, periodic inspection of the blower and blower housing should be
performed by a qualified mechanic at maximum intervals of 500 operating hours.
This inspection requires removal of the blower assembly.
