BATTERY INSTALLATION SAFETY
INSTRUCTIONS
• Always wear protective clothing, gloves and goggles
when handling the battery.
• Do not smoke near the battery, and keep the battery
away from sparks, flames and metal objects.
• Use a wrench with a rubber handle when
connecting the battery.
• The electrolyte is the mixed solution of acid and
water. Do not allow it to contact skin.
• Wash immediately with water if acid contacts the
skin or the eyes.
• Be sure the battery cable connectors are properly
tightened to the battery terminal. Battery cable
connectors that are too tight or loose could damage
the terminal or cause a fire.
• Avoid a short circuit by never placing objects on the
battery and touching both battery terminals at the
same time with a metal object.
• The wet lead-acid battery will release small
amounts of gas in the process of use, particularly in
the charging process. Be sure to charge the battery
in a well-ventilated place.
• Do not add acid into the battery.
• Always keep the battery vertical. The electrolyte in
the battery may spill from the battery if the battery is
tilted or placed on its side.
BATTERY CONNECTION INSTRUCTIONS
Battery cable and torque value:
• The battery cable provides connection among and
between battery, equipment and charging system.
Connect the battery, the charging system and the
equipment with a flexible cable. An improper
connection could lead to poor performance, battery
damage or cause a fire.
• The tightening torque of cable fixation nut shall be
executed according to the following table:
Table 6-10
Nut
specifications
Torque
M8
9 ~ 11 Nm (80 ~ 97 ft-lb)
M10
18 ~ 23 Nm (160 ~ 204 ft-lb)
• Be sure the battery cable connectors are properly
tightened to the battery terminal. Battery cable
connectors that are too tight or loose could damage
the terminal or cause a fire.
• Battery terminals could become corroded if not kept
clean and dry. To prevent corrosion, apply a thin
layer of petroleum jelly or use a terminal protector.
