Section 2 - Operation
Series QP55-G Recreational Vehicle Generator
OPERATION
( ÿ t ï
To start the generator from either the generator
control panel or from the optional remote panel,
proceed as follows;
1. Turn OFF electrical loads using the means pro­
vided in your vehicle (such as a main line cir­
cuit breaker or transfer switch).
NOTE:
If starting from the generator control panel,
turn OFF loads by setting the generator’s main
circuit breaker to the OFF (or open) position. If
starting from a remote panel, turn OFF loads
using the means provided in the vehicle (such as
a main circuit breaker). Electrical load circuits
will be turned ON after the generator has start­
ed, stabilized and warmed up.
2. If you have not started the engine in more than
two weeks, press the Fuel Pump Primer switch
and hold it for about five seconds to prime the
fuel system. However, if the engine is warm,
skip Step 2.
3. Hold the engine Start/Stop switch in the
START position to crank the engine. Release the
switch when the engine starts.

5.
------- Mk CAUTION M. -------------
If the engine does not start after it has been
k cranking for 15 seconds, release the Start/Stop
switch and try again. Holding the switch for
longer than 15 seconds can damage the
starter motor.
Let the engine run at no-load for a few minutes
to stabilize and warm up.
Turn ON electrical loads using the means
provided (such as a main circuit breaker or
transfer switch).
2.6 STOPPING THE GENERATOR
1. Turn OFF all electrical loads using the means
provided (such as a main circuit breaker or
transfer switch).
2. Let generator run at no-load for a few minutes, to
stabilize internal engine generator temperatures.
3. Place the Start/Stop switch in its STOP position.
2.7 APPLYING LOADS TO GENERATOR
When applying electrical loads to the generator,
observe these guidelines:
• Before applying electrical loads, let the generator
stabilize and warm up for a minute or two.
® DO NOT overload the generator.
♦ 2.7.1 LEHING THE ENGINE STABILIZE
The generator supplies correct rated voltage only at
the proper governed speed. Some electrical appli­
ances
may be extremely sensitive to voltage.
Incorrect voltages can damage such appliances.
If electrical loads are applied at reduced operating
speeds, such loads imposed on the engine when suf­
ficient power is not available may shorten engine life.
Never turn ON electrical loads until after the genera­
tor engine has started and stabilized at no-load.
2.8 SUIVIIVIER/WINTER HEAT
RISER SYSTEM
Under certain weather conditions, it is possible for
ice to form in the venturi area of the carburetor.
This condition can be very dangerous because it
can prevent the governor system from functioning
properly, which results in a “runaway” engine.
The most common weather conditions leading to
this problem are temperatures in the range of 25° F
to 35° F (-4° C to 1.7° C), along with high humidity.
This ice formation also can be attributed to the load
being applied during these weather conditions.
Generators running with no-load or light loads
applied usually have the most problems.
The Summer/Winter Lever (Figure 2.4) should be in
the WINTER position for ambient temperatures
below 40° F (4.4° C) and in the SUMMER position
for ambient temperatures above 40° F (4.4° C).
When the heat riser is in the SUMMER (down) posi­
tion (Figure 2.4), air is drawn into the air cleaner
from the upper intake tube.

Heat Riser System
WINTER POSITION
When the heat riser is in the WINTER (up) position,
air is drawn from the lower intake tube, which is
positioned to draw the heated air near the exhaust
manifold.
To prevent carburetor icing, the owner/operator
should physically position the heat riser to the
proper position dependent on the temperature.
