the generator with a transfer switch if the unit is to be
used as a standby power supply. Then continue with the
steps described below:
1.
Perform a manual start of the unit at least once to
verify that the engine is operating correctly.
NOTE:
The lights are automatically disconnected on
startup. The main circuit breaker can be left on if no other
loads are connected, except for the lights. Any connected
external loads must be disconnected by a transfer switch
when starting the unit.
2.
If a check of the remove start circuit is desired:
a.
Remove the wires from the remote start terminal
block. Press the Auto button. The Auto LED with
be lit.
b.
Attach a jumper wire (minimum 16 gauge)
across the two terminals on the remote start
terminal block. This applies a ground to the
controller to close the starting circuit contacts.
The engine should crank, start and run.
c.
Remove the jumper wire form the remote start
terminal block and the engine will stop.
d.
Reconnect any necessary wires form the remote
start switch (transfer switch) to the remote start
terminal block.
3.
Confirm the unit is in Auto mode. The Auto LED
should be lit.
4.
Secure the unit by closing and locking all access
doors.
5.
The unit is now ready for remote starting

NOTE:
The lights require a warm up period of 5-15
minutes before they reach full output. If the lights are shut
down, they require a cool down period of approximately
10 minutes before they can be switched on again.
NOTE:
The light tower uses four 1000W or 1050W
bulbs. When checking or replacing the bulbs, wipe them
with a clean cloth to avoid leaving any grease, oil
residue, or fingerprints on the glass. Any residue can
create a hot spot on the bulb, causing premature bulb
failure.
Engine Derating
All units are subject to derating for altitude and
temperature. Derating reduces the available power for
operating tools and accessories connected to the
receptacles. Typical reductions in performance are 2-4%
for every 1000 ft (305 m) of elevation and 1% per 10ºF
(5.6ºC) increase in ambient air temperature over 72ºF
(22ºC).
Wet Stacking
The unit is powered by a diesel engine. Diesel engines
are subject to “wet stacking” if lightly loaded. Wet
stacking occurs when an engine is run at less than 30%
of its full load capacity, causing unburned fuel to
accumulate in the exhaust system. Wet stacking can be
detected by continuous black exhaust when the unit is
under a constant load. It can also cause fouling of
injectors and buildup on engine valves. Diesel engines
