REGULAR CHECKS AND MAINTENANCE WORK50
A Always wear eye protection when working with
the battery.
1. Remove the mat and cover of left side step, check the
battery fluid level and add distilled water if necessary.
2. If battery fluid be spilt, fill with sulfuric acid solution of
the same concentration.
3. Clean the battery caps (ventilation holes) also.
A When filling battery fluid or distilled water,clean
trash,dust,etc off the top of battery before opening
the battery cap.
BBattery Charging
To avoid personal injury:
A 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.
A When charging battery, make sure battery vent
plugs are securely.
A 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.
A Do not check battery charge by placing a metal
object across the terminals.
Use a voltmeter or hydrometer.
1. Make sure each electrolyte level is to the bottom of
vent wells. If necessary, add distilled water in a well-
ventilated area.
2. The water in the electrolyte evaporates during
recharging. Liquid shortage damages the battery.
Excess liquid spillage damages the excavator.
3. To slow charge the battery, connect the battery
positive terminal to the charge positive terminal and
the negative to the negative, then recharge in the
standard fashion.
4. A boost charge is only for emergencies. It will partially
charge the battery at a high rate and in a short time.
When using a boost-charged battery, it is necessary to
recharge the battery as early as possible.
Failure to do this will shorten the battery's service life.
5. When the specific gravity of electrolyte falls between
1.27 and 1.29 charge has completed.
6. When exchanging an old battery for a new one, use a
battery of equal specification.
