Check Points Of Every 1 Or 2 Months - Kubota SM-E4B Series Workshop Manual

SM-E4B SERIES, WSM

[10] CHECK POINTS OF EVERY 1 OR 2 MONTHS

Recharging
CAUTION
• When the battery is being activated, hydrogen and oxygen
gases in the battery are extremely explosive. Keep open
sparks and flames away from the battery at all times,
especially when charging the battery.
• When charging battery, remove battery vent plugs.
• When disconnecting the cable from the battery, start with
the negative terminal first. When connecting the cable to
the battery, start with the positive terminal first.
• Never check battery charge by placing a metal object
across the posts.
Use a voltmeter or hydrometer.
1) Slow Charging
1. Add distilled water if the electrolyte level is low. When charging,
the amount of electrolyte should be slightly lower than the
specified level to prevent overflow.
2. Connect the battery to the charging unit, following the
manufacture's instructions.
3. As the electrolyte generates gas while charging, remove all port
caps.
4. The electrolyte temperature must not exceed 40 °C (104 °F)
during charging.
If it exceed 40 °C (104 °F), decrease the charging amperage or
stop charging for a while.
5. When charging several batteries in series, charging at the rate
of the smallest battery in the line.
2) Quick Charging
1. Determine the proper charging current and charging time with
the tester attached to the quick charger.
2. Determine the proper charging current as 1/1 of the battery
capacity. If the battery capacity exceeds 50 Ah, consider 50 A
as the maximum.
Precaution for Operating a Quick Charger
• Operating with a quick charger differs according to the type.
Consult the instruction manual and use accordingly.
