Drive System Maintenance; Checking The Tire Pressure - Toro 4573 Operator's Manual

Charging the Battery
Charging the battery produces gasses that can
explode. Never smoke near the battery and
keep sparks and flames away from the battery.
Important: Always keep the battery fully charged
(1.260 specific gravity), especially below 32°F (0°C)
to prevent battery damage.
1. Remove the battery from the chassis; refer to
Removing the Battery.
2. Check the electrolyte level; refer to Checking the
Electrolyte Level.
3. Remove the filler caps from the battery and connect
a 2 amp battery charger to the battery posts.

Checking the Tire Pressure

Service Interval: Every 25 hours/Yearly (whichever
comes first)
Maintain the air pressure in the front tires at 120 kPa
and in the rear tires at 100 kPa. Check the pressure at
the valve stem (Figure 31). Check the tires when they are
cold to get the most accurate pressure reading.
