BLOWER ASSEMBLY
A large turbine type blower is used in the TYMCO Model 210 to generate both the vacuum and
pressure air stream used to sweep. The blower assembly is found on the left side of the
sweeper (See Page 3) and is driven by an auxiliary engine through a sheave and belt system.
WARNING
: Never reach into blower housing for any reason if blower power
band is installed.
WARNING
: Always remove ignition key from sweeper control panel and/or
disconnect battery ground when working on or near the blower
or blower belt.
A. OPERATION
The blower begins to rotate as soon as the auxiliary engine is started. No clutch is
used to engage or disengage the blower.
To increase the blower speed, turn the vernier throttle cable knob counterclockwise
to desired RPM.
Reverse procedure to decrease blower RPM. Use vernier override button on top of
throttle cable knob only for emergency shutdowns.
B. BLOWER RPM SETTING
Blower RPM is set by reading the auxiliary engine tachometer. As a rule, the higher
the blower RPM, the heavier the debris which can be picked up providing the
sweeper is in good operating condition. However, higher RPM results in faster com-
ponent wear so engine RPM should be set according to the debris load on the sur-
face to be swept. The following RPM are recommended:
Kubota Engine Diesel Turbo/Wis-Con
RPM Engine RPM
Paper, leaves, light trash, cans, bottles 1600 - 1800 1300 - 1500
Normal accumulation of dirt, sand, gravel 1800 - 2200 1500 - 1800
Heavy accumulation of dirt, sand, gravel * 2200 - 2400 1800 - 2000
*Sweeper forward travel must also be slower in order to remove this type of debris.
