• Check mirrors and rear view camera (if equipped) on
machine before starting operations. Clean off any dirt and
adjust view for good visibility.
When operating or traveling during poor visibility conditions,
follow the preceding work site rules.
It may not be possible to adjust all visual aids to see all the way
around the machine. Therefore, additional precautions such as
flagman, barricades, etc., should be taken to keep other
personnel out of the work area.
Boost Starting or Charging Engine
Batteries
Follow these instructions to prevent an explosion or fire when
connecting booster cables to batteries:
• Turn "OFF" all electric equipment before connecting leads
to battery. This includes electric switches on battery
charger or battery booster equipment.
• When boost starting from another machine or vehicle do
not allow two machines to touch. Wear safety goggles and
gloves while battery connections are made.
• 24 volt battery units consisting of two series connected 12
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 metal frame of the
machine being boosted or charged. The final booster cable
connection, at metal frame of the machine being charged
or boost started, should be as far away from the batteries
as possible. Refer to Operation and Maintenance Manual,
for proper procedure in this manual.
• Connect positive (+) cable first when installing cables and
disconnect negative (-) cable first when removing them.
