Adjusting Brake
The wet brake system is an internal part of the
transmission and it is adjusted externally without
opening the transmission. There are two sets of brakes
that may require adjustment. Each set consists of two
rotating friction plates placed between three fixed steel
plates operating in oil. Each set of brakes is operated
by it’s respective lever arm. The brakes are properly
adjusted at the factory.
To adjust the brakes:
• Stop the vehicle on a level surface.
• Turn the ignition key to the STOP position and
remove the key.
• Block the front wheels, position the shift lever into
neutral, and make sure parking brake in not
activated.
• Use a jack to raise the rear wheels at least one inch
off the ground. Then use blocks or stands to
support the machine.
• Disconnect brake arm return spring. See Figure 20.
• Loosen the front and rear jam nuts.
Figure 20
• Push the brake lever arm forward until the internal
brake disc stop is detected.
• Run up the jam nut of the rear side until it touches
and then back off one turn.
• Tighten the front side jam nut.
• Check the brake pedal by hand. It should have 3/4”
free travel.
• Hook up the return spring.
• Rotate the rear wheels by hand with brake pedal
released. The wheels should rotate freely.
• Cautiously complete the testing on level ground by
operating the machine and applying brakes in a
normal manner.
• Repeat the adjustment procedure if necessary.
Adjusting Throttle Pedal
The throttle pedal assembly can be adjusted for comfort
slightly higher or lower by lining up the holes of the
lower pedal assembly with either the upper two or lower
two holes of the upper pedal assembly. See Figure 21.

cleaning the body panels. Avoid any abrasive cleaner
or rubbing compounds for these will damage the body
