Do not handle a naked flame in the vicinity of batteries because of a risk of explosion. Do not smoke when working with batteries. Do not leave tools or other metal implements on top of the battery. Sparking or a short-circuit may cause the battery to explode. When batteries are recharged, the cell plugs must be closed firmly to prevent splashing of battery fluid. Battery fluid is a corrosive acid solution; avoid getting it on your skin or in your eyes. The battery fluid develops explosive gas at the end phase of recharging. Therefore, make sure that the battery has sufficient ventilation (this does not apply to maintenance-free batteries). A low battery charge status may damage the battery during long-time use. 1600 and 2000 kg capacity trucks 2 V/cell. 1300 kg capacity trucks 10.5 V/battery (1.75 V/cell).
Recharging the battery Make sure that the charger is the appropriate model and that the battery has sufficient ventilation. 1. 2. 3. 4. 5.
Park the truck in a reserved recharging place. Switch off the power from the key switch. Make sure that the charger has been switched off. Disconnect the battery connector and connect it to the charger. Switch on the charger.
After recharging 1. 2. 3.
Switch off the charger. Disconnect the battery connector from the charger. Grab the plugs; do not pull the cables. Check the battery according to the battery manufacturer's maintenance instructions.
Measuring the battery's specific gravity
Measure the specific gravity of the battery fluid according to the manufacturer's instructions. The acid density of a fully charged battery is 1.28 to 1.30 at +30°C. The gravity is • • • •
1.24 when the battery is 3/4 charged. 1.20 when the battery is 1/2 charged. 1.16 when the battery is 1/4 charged. 1.15 when the battery is empty. Charge the battery immediately.
