Hydraulic System Maintenance; Changing The Hydraulic Filter - Toro 22303 Dingo 320-D Operator's Manual

Important: Do not overfill the battery
because electrolyte (sulfuric acid) can
cause severe corrosion and damage to the
chassis.
5. Wait five to ten minutes after filling the battery
cells. Add distilled water, if necessary, until
the electrolyte level is up to the Upper line
(Figure 33) on the battery case.
6. Install the battery filler caps.
Charging the Battery
Charging the battery produces gasses that
can explode.
Never smoke near the battery and keep
sparks and flames away from battery.
Important: Always keep the battery
fully charged (1.265 specific gravity). This
is especially important to prevent battery
damage when the temperature is below 325F
(05C).
1. Check the electrolyte level; refer to Checking
Electrolyte Level.
2. Make sure the filler caps are installed in the
battery.
3. Charge the battery for 10 to 15 minutes at
25 to 30 amps or 30 minutes at 4 to 6 amps
(Figure 34). Do not overcharge the battery.
