Briggs & Stratton PRO4000 manual Cold Weather Operation, Creating a Temporary Cold Weather Shelter

Cold Weather Operation

Under certain weather conditions (temperatures below 40°F [4°C] combined with high humidity), your generator may experience icing of the carburetor and/or the crankcase breather system. To reduce this problem, you need to perform the following:

1.Make sure generator has clean, fresh fuel.

2.Open fuel valve (turn valve to open position).

3.Use SAE 5W-30 oil.

4.Check oil level daily or after every eight (8) hours of operation.

5.Maintain generator following Maintenance Schedule in Maintenance section.

6.Shelter unit from elements.

Creating a Temporary Cold Weather Shelter

1.For temporary shelter, the original shipping carton can be used.

2.Cut off top carton flaps and one long side of carton to expose muffler side of unit. If required, tape up other sides of carton to fit over generator as shown.

NOTICE If required, remove wheel kit to fit carton over generator as shown.

3.Cut appropriate slots to access receptacles of unit.

4.Face exposed end away from wind and elements.

5.Locate generator as described in the section Generator Location. Keep exhaust gas from entering a confined area through windows, doors, ventilation intakes or other openings.

WARNING Running engine gives off carbon

monoxide, an odorless, colorless, poison gas.

Breathing carbon monoxide can cause headache, fatigue, dizziness, vomiting, confusion, seizures,

nausea, fainting or death.

•Operate generator ONLY outdoors.

•Install a battery operated carbon monoxide alarm near the bedrooms.

•Keep exhaust gas from entering a confined area through windows, doors, ventilation intakes, or other openings.

•DO NOT start or run engine indoors or in an enclosed area, (even if windows and doors are open), including the generator compartment of a recreational vehicle (RV).

6.Start generator as described in the section Starting the Engine, then place carton over generator. Keep at least 5 ft. (1.5 m) clearance on all sides of generator including overhead with shelter in place.

WARNING Contact with muffler area can result in serious burns.

Exhaust heat/gases can ignite combustibles, structures or damage

fuel tank causing a fire.

•DO NOT touch hot parts and AVOID hot exhaust gases.

•Allow equipment to cool before touching.

•Keep at least 5 feet (152 cm) of clearance on all sides of generator including overhead.

•Remove shelter when temperatures are above 40°F [4°C].

7.Remove shelter when temperatures are above 40°F [4°C].

8.Turn engine OFF and let cool two (2) minutes before refueling. Let any spilled fuel evaporate before starting engine.

Building a Cold Weather Shelter

1.Using non combustible material with a fire rating of at least one hour, build a shelter that will enclose three sides and the top of the generator. Make sure muffler side of generator is exposed.

NOTICE Contact your local building material supplier for non combustible materials with a fire rating of at least one hour.

NOTICE Be sure shelter can easily be repositioned for change in wind direction.

2.DO NOT enclose generator any more than shown. Shelter should hold enough heat created by the generator to prevent icing problem.

NOTICE If a wheel kit is installed on the generator, enlarge shelter accordingly.

3.Follow steps 3 through 8 as described previously in Creating a Temporary Cold Weather Shelter.
