BLOWER ASSEMBLY
A large turbine type blower is used in the TYMCO Model 600 to generate both the vacuum and
pressure air stream with which to sweep. The blower assembly is found on the left side of the
sweeper in the blower housing (see Page 3) and is driven by an auxiliary engine through a
sheave and belt system.
WARNING : Never reach into the 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 blower.
To increase blower speed, use vernier throttle control on sweeper console. Turn the
knob counter-clockwise to desired RPM.
NOTE: If sweeper is equipped with an electric
linear actuator, use the throttle switch.
Reverse procedure to decrease blower RPM. Use vernier override button on top of
throttle knob
only for emergency shutdowns .
B. BLOWER RPM SETTING
The Model 600 standard Turbo Charged Auxiliary Engine uses a sheave ratio of 1.45
to 1 - meaning that the blower RPM is 1.45 times faster than the engine RPM. Blower
RPM is; therefore, 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 component wear so
engine RPM should be set according to the debris load on the street. The following RPM
settings are recommended:
ENGINE RPM
Paper, Leaves, Light Trash 1500
Normal Accumulation of Dirt, Sand and Gravel 1600
Heavy Accumulation of Dirt, Sand and Gravel 1800
DO NOT EXCEED 2400-STD. (2000-TURBO) ENGINE RPM WITHOUT FIRST
CONSULTING THE FACTORY.
