MAINTENANCE
SKIDS
The skids are located on both sides of the brush
compartment. They skim the ground when the
conveyor is lowered into the sweeping position and
are designed to contain debris between the main
brush and the conveyor lip.
Check the skids for wear after every 100 hours of
operation. The skids should be replaced when the
thickness is less than 1 mm (0.04 in).
The skids are attached to the upper plate by
means of a rubber gusset that absorbs shock.
Check the rubber gussets every 100 hours of
operation for damage or wear.
BRAKES AND TIRES
SERVICE BRAKES
The wet multi
−
disc service brakes are located
on all four wheels. These brakes are
fi
lled with
universal tractor
fl
uid (Mobil 424). The
fi
ll/check
ports are located on the side of the wheel hubs.
The drain ports are located on the bottom of the
wheel hubs. Check the
fl
uid level after every 400
hours of operation. Change the
fl
uid after every
1600 hours of operation.
TIRES
The machine tires are pneumatic. The wheels
consist of a 3-piece rim,
fl
ap, tube, and tire.
Check the tire pressure every 50 hours of
operation. The proper tire air pressure is:
Bias Ply Tire
930
−
1000 kPa (135
−
145 psi)
Radial Tire
930
−
1000 kPa (135
−
145 psi)
NOTE: The machine is equipped with 3-piece rims.
If the tire pressure falls below 550 kPa (80 psi),
the tire and wheel assembly should be brought to
an industrial tire service center for repair and/or
refi lling.
Check the tires for wear and rotate every 200
hours of operation.
