SECTION 4 - MACHINE OPERATION
3121636 – JLG Lift – 4-3
NOTE: At low temperatures start the motor and let it run for a
few minutes, until the hydraulic oil circulates and
reaches at least 50°F (10°C) before operating the plat-
form.
Gas Engine Shutdown Procedure
1. Remove all load and allow engine to operate at
low speed for 3-5 minutes; this allows further
reduction of internal engine temperature.
2. Turn off the gas engine by using the gas engine
button (item 11, Figure 4-4.) on the platform/
remote control box.
3. The shutdown procedure takes about 1 minute,
wait for complete shut-off (display off ).
4. Push POWER/EMERGENCY STOP switches at the
platform and ground in, to the off position.
5. Turn engine key to off.
Electric Engine Starting Procedure - AC Voltage Machine
ENSURE THE ELECTRICAL CIRCUIT BEING USED IS THE SAME VOLTAGE
AND FREQUENCY INDICATED ON THE ELECTRIC ENGINE PLATE. USE AN
AC EXTENSION CORD WITH SUFFICIENT AMPERAGE CAPACITY TO PROP-
ERLY POWER THE MACHINE.
CHECK THE EFFICIENCY OF THE GROUND ON THE AC CIRCUIT, IF THE CIR-
CUIT IS NOT GROUNDED, INSERT A GROUND DISCHARGER TO GROUND
AND CONNECT IT TO THE GROUND CLAMP ON THE MACHINE
(ITEM 3 –
SEE PHOTO).
1. Before connecting the machine to the electrical
circuit, ensure the key on the gas engine is in the
ON position.
2. Power the machine using a heavy duty AC power
cord with sufficient amperage capacity, through
the connector (item 2) positioned near the electric
engine.
3. Turn on the circuit breaker switch (item 1) posi-
tioned behind the clear cover near the electric
engine (— symbol is ON - O symbol is OFF).
4. Start the electric engine using the engine start
button at the ground/emergency control box.
(item 5 - Figure 4-1.) and operate machine.
