ADJUSTMENTS/REPAIRS
BRAKE TENSION ADJUSTMENT
1
See Figure 8.
Remove the Floor Weldment to access the Rod End
(A)
.
2
Remove the Nyloc
Nut
(B)
and remove the Rod End
(A)
from the Brake
Pedal Assembly.
3
Loosen the Jam Nut
(C)
and rotate the Rod End
(A)
in the appropriate
direction to adjust the brake tension.
4
When the brake tension has been adjusted, tighten the Jam Nut
(C)
.
5
Reinstall the Rod End
(A)
into the Brake Pedal Assembly, then reinstall
and tighten the Nyloc
Nut
(B)
.
6
Check the brake tension as follows:
a. Jack up the rear of the machine to get the rear wheels off of the
ground.
CAUTION!
Make sure to follow the instructions in the JACKING THE MACHINE
section. Jack the machine at the designated locations only.
b. Manually rotate the rear wheels to check the brake tension. The
tension is set correctly when the wheels cannot be rotated with the
parking brake applied to three “clicks”, but will rotate freely when the park-
ing brake is off.
c. Readjust the brake tension as necessary following steps
2
through
5
above.
7
When the brake tension is adjusted correctly, lower the machine and reinstall the Floor Weldment.

FOOT PEDAL/HYDROBACK SYSTEM OVERVIEW
See Figure 9. A Hydroback centering unit
(D)
, installed between the Push/Pull Control Cable
(A)
and the drive Piston Pump Lever Weldment
(E)
,
returns the pedal and Piston Pump
(G)
to the neutral position when the pedal is released. A rotary potentiometer, called the Rotary Sensor
(F)
, is
attached to the Piston Pump, and the resistance through the Rotary Sensor will vary with the position of the Piston Pump Lever Weldment. When
the engine is started, the Control Board (Driver Box) checks the Rotary Sensor resistance to con
fi
rm that the drive pedal and Piston Pump are in the
neutral position before the engine can be started. This is to prevent the machine from moving forward or backward when the engine is
fi
rst started,
or unless the drive pedal is depressed.
The resistance that the Control Board must see through the Rotary Sensor in order to allow the engine to be started is de
fi
ned as a nominal resis-
tance, plus or minus a percentage of the nominal resistance. This resistance range is referred to as the neutral “deadband.” If the Control Board fails
to see the Rotary Sensor resistance in the deadband, it will send a “start-inhibit” signal to the Relay PCB which will prevent the engine from starting.
Once the engine is started with the machine in neutral, the Control Board will enable the solution, scrub and vacuum systems once it sees that the
resistance through the Rotary Sensor is out of the deadband due to the drive pedal being depressed.
Dependable starting and responsive operation depends on the drive pedal and Piston Pump returning to a repeatable neutral position when the
pedal is released.
