Replace Batteries

IMPORTANT: Before adjusting electrical system or
welding on the machine, disconnect the negative
side of the battery, or turn the battery disconnect
switch to OFF position.
Your machine has two 12-volt batteries with negative (-)
ground.
If one battery in a 24-volt system has failed but the other
is still good, replace the failed battery with an operable
battery of the same type. For example, replace a failed
maintenance-free battery with a new maintenance-free
battery. Different types of batteries may have different
rates of charge. This difference could overload one of the
batteries and cause it to fail.
Check Monitor Functions and All Other
Instrument Operation
--- every 10 hours (daily)
Run the engine at low idle when checking the instruments.
The monitor indicates alarm, caution and confirmation
status in red, orange, and normal operative condition in
blue or green respectively. Check each gauge or meter if its
needle is moved with the key switch ON. The needle shall
be moved to the blue range when normal and to the red
range when abnormal. Refer to the Group of Operator's
Station in Section 1 for more information.

Check Work Lights

--- every 10 hours (daily)
d
CAUTION: If any burned-out light is found,
immediately replace it with a new one.
Visually check all work lights that they normally illuminate
and/or flash from the front and rear sides of the machine.
