Charging The Battery; Checking The Battery; Removing/Installing And Replacing The Battery - Kubota U17-3a Operating Instructions Manual

Charging the battery

Charge batteries only in sufficiently ventilated rooms. Smoking, uncovered lights or fire are not
allowed in these rooms.
Explosive gas is created when charging batteries. Open flames can cause an explosion.
Remove the fill caps when charging batteries that are virtually empty. Leave the fill caps inside
(not empty) batteries that are only charged for maintenance purposes, the fill caps can stay in the
batteries.
The battery can only be charged if the starter switch is in the STOP position and the key re-
moved.
If the battery is charged when installed in the vehicle, the engine compartment cover must be left
open during the charging procedure. After the charging procedure is completed, the engine
compartment cover must be left open for ventilation for about 1 hour prior to start-up. → Risk of
explosion.

acid density differs considerably among the individual cells of a battery, the battery probably has a defect.
Check the affected battery with a battery tester and contact trained personnel.

Removing/installing and replacing the battery
