Performing Pre-Starting
Checks
Service Interval:
Before each use or daily Check the
following items each time you begin
using the machine for the day:
•
Ensure that the batteries are charged before using the
machine;
Charging the Batteries (page 33)
.
•
Check the water level in the batteries;
Level of the Batteries (page 34)
.
•
Check brake-fluid level, and add the specified brake fluids
as needed; refer to
Checking the Brake-Fluid Level (page
41)
.
•
Check the air pressure in the tires; refer to
Tire Pressure (page 21)
.
•
Check the transaxle-fluid level; refer to
Transaxle-Fluid Level (page 40)
.
•
Check the brake pedal operation.
•
Check to see that the lights are working.
•
Turn the steering wheel to the left and right to check
steering response.
•
Check for loose parts and any other noticeable
malfunctions.
Note:
Shut off the machine and allow all moving parts
to stop before checking for loose parts and other wear
and damage.
If any of the above items are not correct, notify your
mechanic or check with your supervisor before taking the
machine out for the day. Your supervisor may want you to
check other items on a daily basis, so ask him or her about
additional operator’s responsibilities.
Checking the Tire Pressure
Service Interval:
Before each use or daily
Tire Air Pressure Range:
165 to 207 kPa (24 to 30 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 165 to 207 kPa (24 to 30 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 that
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.
Important:
Repeated deep-discharge cycles reduces
the battery life.
Lead-acid batteries produce electricity through a chemical
reaction between 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 100 to 150 discharge/charge cycles.

Break-in period (100 to
150 cycles)
After the break-in period, the battery maintains a high
capacity for many cycles. The number of cycles that a battery
performs depends on the following:
•
Battery maintenance—improper maintenance severely
reduces the life of the batteries.
•
Depth of discharge between charge cycles—
the deeper
the batteries are discharged on a regular basis
