Checking the Tire Air Pressure
Service Interval:
Before each use or daily
Tire Air Pressure Range:
55 to 103 kPa (8 to 22 psi)
Important:
Do not exceed the maximum air pressure
indicated on the sidewall of the tire.
Note:
The air pressure needed in the tires is determined by
the payload that you intend to carry.
1.
Check the air pressure in the tires.
Note:
The air pressure range in the front and rear tires
is 55 to 103 kPa (8 to 22 psi).
•
Use lower air pressure in the tires for lighter
payloads, for less the soil compaction, for a
smoother the ride, and to minimize tire marks in
the ground.
•
Use higher air pressure in the tires for carrying
heavier payloads at higher speeds.
2.
If needed, adjust the air pressure in the tires by adding
or removing air in the tires.
Understanding and Using the
Battery System
Understanding Deep-Cycle Batteries
The machine contains 8 deep cycle, lead-acid batteries which
supply power to the motor and accessories. A deep-cycle
battery is not the same as an automobile battery. An
automobile battery is designed to provide a surge of power to
start the machine and moderate power to run the lights and
accessories when the motor if off or idling. The alternator
then continuously charges as the automobile runs. As such,
an automobile battery seldom drops below 90% of the
maximum charge level.
A deep-cycle battery is designed to be a primary power
source to provide a sustained output. Deep-cycle batteries are
typically discharged as low as 20 to 30% of the maximum
charge level. A discharge this low is considered a deep
discharge.
Lead-acid batteries produce electricity through a chemical
reaction between coated lead plates and sulfuric acid.
Charging a battery reverses the chemical reaction, allowing
the battery to once again produce electricity.
A battery is a perishable item that has a limited lifetime
(
). When a battery is new, it requires a break-in
period to establish efficient electrical production. This break
in period usually requires 20 to 50 discharge/charge cycles.

Break-in period (20 to 50
cycles)
After the break-in period, the battery will maintain a high
capacity for many cycles. The number of cycles a battery will
perform is dependant on the following:
•
Battery maintenance—improper maintenance will
severely reduce the life of the batteries.
•
Depth of discharge between charge cycles—
the deeper
the batteries are discharged on a regular basis
between charges, the less life they will have.
