THERMO SENTRY
The Thermo Sentry
senses the temperature of
the air pulled up from the hopper. If there is a fire
in the hopper, the Thermo Sentry
stops the
vacuum fan and cuts off the air flow.
Reset the Thermo Sentry
by pushing in its reset
button.
BRUSHES
MAIN BRUSH
The main brush is cylindrical and spans the width
of the machine, sweeping debris into the hopper.
Check the brush daily for wear or damage.
Remove any string or wire tangled on the main
brush, main brush drive hub, or main brush idler
hub.
Check the main brush pattern daily. The pattern
should be 50 to 65 mm wide with the main brush
in the Down position. Adjust the main brush
pattern by turning the main brush pressure knob
located next to the brush position lever.
Rotate the main brush end-for-end every
50 hours of operation for maximum brush life and
best sweeping performance.
Replace the main brush when the remaining
bristles measure 30 mm in length.
TO REPLACE MAIN BRUSH
1. Stop the engine and set the machine parking
brake.
FOR SAFETY: Before leaving or
servicing machine; stop on level
surface, set parking brake, turn off
machine and remove key.
2. Raise the main brush.
