Ensure that there are no leaks and ll hydrau-
lic tank with hydraulic oil before restarting
machine.
8. High Temperature Hydraulic Oil Indica-
tor – illuminates when the hydraulic oil tem-
perature exceeds 190° F. If this light illumi-
nates, STOP operation of machine and turn
machine OFF. Clean debris from radiator/oil
cooler and screen. Then restart machine to
allow the hydraulic oil to cool properly. If this
light illuminates repeatedly, further technical
troubleshooting is necessary.

wheels only and not intended to roll on the
ground continuously. See operation section in
manual for adjustment instructions.
2. Hydraulic Motor – powers the sweeping
rotor and paddle.
3. Chain Drive – connects sprockets of hy-
draulic motor, paddle, and sweeping rotor.
4. Lower Deck Skirting – seals the deck o
at the ground level to reduce dust and con-
tain debris inside the deck.
5. Upper Deck Seal – creates a seal be-
tween the deck and the deck transition.
6. Adjustable Gauge Wheels – controls the
sweeping height of the deck and sweeping
rotor. See Operation section in manual for
adjustment instructions.
7. Deck Lift Safety Lock – used to secure
the deck in the UP position. Safety lock is
located on the front RH side of the deck. See
instructions in the safety lock section.
Hopper Identication
1. Hopper Lift Cylinders – used to raise and
lower the hopper.
2. Hopper Lift Safety Locks – used to se-
cure the hopper in UP position. Safety locks
are located on both lift cylinders and should
be used anytime a person is below the hop-
per. See instructions in the safety locks sec-
tion.
3. Pilot Operated Check Valves – included
in both the hopper lift and hopper door hy-
draulic plumbing circuit. See the hydraulic
schematic in the parts manual for further
details.
4. Hopper Door Cylinders – used to open
and close the hopper door.
5. Hopper Door Safety Lock – use safety
lock to secure hopper door in the OPEN posi-
tion. Safety lock should be used when work-
