Performing Pre-Starting Checks; Checking The Tire Pressure; Understanding And Using The Battery System - Toro Workman GTX Operator's Manual

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
•
Check the water level in the batteries;
the Water Level of the Batteries (page
•
Check brake-fluid level, and add the specified
brake fluids as needed; refer to
Brake-Fluid Level (page
•
Check the air pressure in the tires; refer to
Checking the Tire Pressure (page
•
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 (Figure 17). 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.
