INSPECTING THE BATTERY
Battery condition is critical to machine performance and
safe operation. A battery with improper electrolyte level
or damaged cables and wiring may harm battery parts
and may pose dangerous conditions.
ELECTROCUTION HAZARD
• Contact with live circuit may
cause serious injury or death. Be
sure to wear goggles, gloves and
protective clothing.
• Remove all rings, watches and
other jewelry.
CHEMICAL BURN HAZARD
Avoid battery acid spills or contact
with unprotected skin. If battery acid
comes into contact with skin, wash
the skin immediately with plenty of
water and seek medical attention
immediately.
If battery acid spills, use water mixed
with bicarbonate (baking soda) to
neutralize the acid.
• Inspect the battery level to make sure the consumed
battery power is no more than 80% of the total
capacity. Charge the battery after each use.
• Ensure the battery cells are wired reliably with the
locking nuts torqued to the specifications as below:
Nut type Torque
M8 9～11Nm (6.6～8.1ft-lb)
M10 18～23Nm (13.2～17ft-lb)
NOTICE
Improper connection may cause reduced
performance, damaged terminals, fusions and
even fires.
• Ensure the battery negative and positive are
correctly connected.
• Ensure the battery connections are not corroded.
• Check the battery electrolyte level is proper (for
lead-acid battery requiring maintenance)
• Check the battery box for accumulation of water,
and if any, clear the water.
