MAINTENANCE INSTRUCTIONS
Rear Axle: Check fluid level in the rear axle per the
recommended maintenance schedule. The rear axle is
provided with a fluid level check/fill plug (Figure 18) located
at the bottom of the differential. With the vehicle on level
ground, clean the area around the check/fill plug and remove
plug. The correct fluid level is just below the bottom of the
threaded hole. If fluid levels are low, add as required until it
starts to seep from the hole. Install the check/fill plug.
F IGURE 18
To replace the fluid, lift the vehicle per the lifting procedures.
Remove the rear axle cover and drain out the fluid into a
container. Clean cover mating surfaces as required with
proper scraping tool. Ensure cover lip is not bent. Apply thin
bead of RTV sealant and torque cover bolts 16-24 lb-ft.
Add 10-14 oz. 80W-90 Hypoid gear oil through the check/fill
plug hole or until fluid just starts to seep from the hole.
B RAKES
The vehicle is equipped with a pair of rear mechanical drum
brakes which only engage for parking and/or emergency
stopping Service mechanical brakes per the recommended
maintenance schedule. Adjustments are made by turning the
connecting rod with a wrench (Figure 19). Normal braking
uses the regenerative braking controlled by the Combination
Accelerator/Brake Pedal. (The amount of regenerative
braking or deceleration can be adjusted within the Curtis
Motor Controller. See instructions on Page 29).

T IRES AND W HEELS
This series is offered in two tow capacity versions: 2,000
pound (907 kg) tow capacity standard transaxle and 5,000
pound (2,268 kg) tow capacity tugger transaxle. The
standard transaxle has a four bolt pattern for the wheels,
whereas the tugger transaxle has a five bolt pattern.
The following tire options are offered with the SC series
vehicle:
1) Pneumatic tires (standard)
2) Foam-filled tires
3) Solid tires (black)
4) Solid non-marking tires (off-white)
5) Soft solid tires
Pneumatic tires are tubeless tires filled with air and mounted
on one piece rims. They offer the smoothest ride but do
require regular maintenance to ensure proper air levels are
maintained and require immediate repair should they go flat.
Foam-filled tires replace the air inside pneumatic tires with a
foam compound and are mounted on one piece rims. This
retains the smoother ride of pneumatic tires but eliminates
the regular maintenance associated with pneumatic tires.
However, if a vehicle equipped with foam-filled tires sits for
extended periods of time, flat spots may form.
Solid tires are solid rubber compound mounted on a two
piece rim. They eliminate the possibility of flat spots and the
maintenance associated with pneumatic tires but because
they are solid, they do not provide as smooth a ride as
pneumatic tires. Solid non-marking tires operate in the same
manner but are made of a rubber compound that prevents
black marks on floors.
Soft Solid tires are a rubber wheel which has molded
recesses in the tire that create a smoother ride similar to a
pneumatic tire.
