SECTION 4 - MACHINE OPERATION
3121210 – JLG Lift – 4-11
Activation of the Manual Charge button will start the engine
and initiate the charging cycle even if the batteries are
charged above the level of automatic start. The operator can
initiate the charge cycle to charge the batteries to the maxi-
mum level. The charging cycle will include finishing phase
similar to conventional chargers.
4.9 INVERTER
The inverter converts 48 VDC to 110 VAC to allow operation
of power tools from the machine’s batteries.
• The inverter is operational when the emergency stop
switch is pulled out.
• The machine and inverter can be operated at the same
time.
• The inverter will shut off at approximately 42 VDC and stay
off until the emergency stop switch is recycled. It will oper-
ate again until voltage drops to 42 VDC.
• The machine will operate down to 36 VDC.
• The inverter will shut down if the high temperature light
indicated overheating. It will automatically turn back on
when cooled.
• The overload light indicates an output wiring short circuit
or a load that is too large for the rating of the inverter.
