Safety
Disconnect Batteries Before Electrical
Service or Electrical Welding
Remove cable to negative terminal first when disconnecting
cable. Connect positive terminal cables first when installing a
battery.
Use Low Heat Portable Lighting
Hot surfaces on trouble lights or portable work lights can set off
fuel or battery explosive gases.
Boost Starting or Charging Engine
Batteries
If any mistake is made in the method of connecting the booster
cables, it may cause an explosion or fire. Always do the
following:
• Turn off all electrical equipment before connecting
leads to the battery. This includes electrical switches
on the battery charger or boost starting equipment.
• When boost starting from another machine or vehicle
do not allow the two machines to touch. Wear safety
glasses or goggles while required battery
connections are made.
• 24 volt battery units consisting of two series
connected twelve volt batteries have a cable
connecting one positive terminal on one of the 12 volt
batteries to a negative terminal on the other battery.
Booster or charger cable connections must be made
between the nonseries connected positive terminals
and between the negative terminal of the booster
battery and the metal frame of the machine being
boosted or charged. Refer to the procedure and
illustration in “Starting with Auxiliary Batteries” on
page 3-8 of this manual.
• Connect positive cable first when installing cables
and disconnect the negative cable first when
removing them. The final cable connection, at the
metal frame of the machine being charged or boost
started, must be as faraway from the batteries as
possible.
