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 PROPERLY POWER THE MACHINE.
CHECK THE EFFICIENCY OF THE GROUND ON THE AC CIRCUIT, IF
THE CIRCUIT IS NOT GROUNDED, INSERT A GROUND DIS-
CHARGER TO GROUND AND CONNECT IT TO THE GROUND CLAMP
ON THE MACHINE (ITEM 1 – SEE PHOTO).
1. Before connecting the machine to the electrical cir-
cuit, ensure the key on the gas/diesel engine is in
the OFF 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 3) positioned
on the left side of the machine next to the electric
engine (— symbol is ON - O symbol is OFF).
4. Start the electric engine using the engine start but-
ton at the ground/emergency control box. (item 5 -
Figure 4-1.) and operate machine.
5. When finished operating with the electric engine,
turn off switch (item 3), unhook the electric AC cord
from receptacle (item 2), and disconnect ground dis-
charger cable (item 1), if it was required.
NOTE: At low temperatures start the motor and let it run for a
few minutes, so that the hydraulic oil circulates and
reaches at least 50°F (10°C) before operating the plat-
form.
