ADJUSTING THE DIRECTIONAL CONTROL
RETURN SPRING
You may encounter “creeping” problems from
time to time. Creeping means the machine moves
backward or forward when the forward/reverse
pedal is in neutral. A grinding noise when the
engine is shut down is a so an indicator that the
directional control return spring needs adjusting. If
this occurs, perform the procedure which follows:
1. Turn off the engine, engage the parking brake
and chock both wheels.
2. Jack the rear of the machine so that the rear
tire just clears the floor. Use two jack stands to
support the machine.
WARNING
DO NOT USE A JACK ALONE TO HOLD THE
MACHINE!!! Use jack stands rated to support
the weight of the machine.
3. Locate the forward / reverse adjustment
bracket mounted beneath the pump on the
pump mounting plate.
4. Slightly loosen the bolt on the center of the
bracket.
5. Loosen the locking nut on each of the
adjusting bolts on the side of the bracket
closest to the pump mounting plate.
6. From the operator’s seat, start the engine and
run at half throttle.
7. Turn the adjusting bolts while watching the
rear wheel. Continue to adjust until the
rear wheel does not turn in either direction.
8. Fully open the throttle. Push the directional
control pedal forward and backward to
be sure the pump stays in neutral. Check the
wheel again and adjust as needed until the
wheel remains motionless.
9. Retighten all the locking nuts and bolts.
10. Turn the engine off and lower the machine to
the floor.
11. Once the broom is started onto the drive hubs,
rotate the broom counter-clockwise while
pushing lightly against the broom.
HOPPER
NOTE: It is not usually necessary to remove
the hopper on high dump models.
However, if it becomes necessary for
maintenance or to install an option, use
the following procedure to remove:
High Dump Hopper Removal
1. Park the machine on a level surface and
engage the parking brake.
2. Raise the hopper and position the high dump
hopper dolly, a platform truck or similar four
wheeled cart under the hopper.
3. Set the hopper down on the truck and turn the
engine off.
4. Cycle the rotation control handle (#2) in both
positions to relieve any residual hydraulic
pressure.
5. Remove three bolts, washers, nuts and
backing plate.
6. Disconnect the wire harness connections at
the right side of the hopper.
7. While spreading the dump arms slightly, roll
the hopper away from the machine.
High Dump Hopper Replacement
1. Position the hopper on the dolly so as to align
the mounting holes in the sides of the hopper
with the rotation mounts on the arms. Lift
arms should be positioned about ⅓ of the way
up.
2. Engage the lift arm rotation plates with the
mounting bolts on each side of the hopper.
3. Start the machine and lift the hopper.
4. Drive away from the hopper dolly or cart.
5. Lower the hopper.
6. Engage the wire connections at the right side
of the hopper.
