32 Owner’s Manual for Mobile Generator
Operation
weather starting aids are required at temperatures below
-13 °F (-25 °C) or at altitudes above 5,000 ft (1,500 m).
The use of correct grade oil (see Recommended Oil
Types) is critical to achieving adequate cold weather
cranking speed. Synthetic oils have improved flow at low
temperatures.
The oil pan heater, battery heater and fuel filter heater (if
equipped) are activated with a thermostat and will turn on
and off as needed. The block heater is powered by a
shore power 120V electrical connection that can be
found in the convenience receptacle. The crankcase
ventilation heater is powered by the generator and will
stay on when the engine is operating in cold weather
conditions.
Cold Weather Starting GuidelinesUse cold weather
starting aids as needed according to Figure . Follow
supplier instructions for starting aids provided on engine.
A booster battery can be connected if needed (see Using
a Booster Battery or Charger (If Equipped)).
NOTE: Turn key to ON but do not crank engine until
Engine Preheat Indicator goes off.
NOTE: Additional information on cold weather operation
is available from your local GMASD.
Using a Booster Battery or
Charger (If Equipped)
See Figure 3-5. A 12 volt booster battery can be
connected in parallel with batteries on the unit to aid in
cold weather starting. ALWAYS use heavy-duty jumper
cables.
Parallel:
• Amps = Twice as a single battery
• Volts = Same as single battery
Figure 3-5. Parallel
1. Connect booster battery or batteries to produce the
required system current.
NOTE: To avoid sparks, do not allow the free ends of
jumper cables to touch engine.
