Generac 02010-2, 04164-2 owner manual Automatic Choke Gasoline only, Before Starting the Engine

Section 2 – Operation

PRIMEPACT 50 Recreational Vehicle Generator

2.3AUTOMATIC CHOKE (GASOLINE ONLY)

The engine is equipped with an automatic choke that consists of two main components: a choke solenoid and prechoke.

◆2.3.1 CHOKE SOLENOID

During engine cranking (Start/Stop switch at START), a solid-state choke module signals the choke solenoid to activate and cycle (choke on/choke off) until the engine starts. The choke solenoid thus opens and closes the carburetor choke valve only when the engine is cranking. When the engine starts, the choke stops cycling.

◆2.3.2 PRECHOKE

The choke system also has a temperature-sensitive metal strip that adjusts choke valve angle according to ambient temperatures (i.e., in cold ambient tem- peratures, choke valve closes more). Once the engine starts, an element heats the temperature-sensitive strip to a normal operating condition, opening the choke valve. This may take about three minutes in cooler weather.

2.4BEFORE STARTING THE ENGINE

NOTE:

Instructions and information in this manual assume the generator has been properly installed, connected, serviced, tested and adjusted by a qualified installation technician or installation contractor.

◆2.4.1 INSTALLATION

Generator installation must have been properly com- pleted so it complies with all applicable codes, stan- dards and regulations and with the manufacturer's recommendations.

◆2.4.2 ENGINE LUBRICATION

Have the engine crankcase properly serviced with the recommended oil before starting. Refer to Section 1.5.4 (Page 6) and Sections 3.1 and 3.2 (Page 12) for oil ser- vicing procedures and recommendations.

◆2.4.3 FUEL SUPPLY

The engine must have an adequate supply of proper fuel to operate. Before starting it, check that sufficient fuel is available.

NOTE:

Depending on the installation, the generator may have either a separate fuel tank, or it may “share” the vehicle engine’s fuel tank.

◆2.4.4 COOLING AND VENTILATING AIR

Air inlet and outlet openings in the generator com- partment must be open and unobstructed for contin- ued proper operation. Without sufficient cooling and ventilating airflow, the engine/generator quickly over- heats, which causes it to shut down and may damage the generator.

◆2.4.5 ENGINE EXHAUST GAS

Before starting the generator engine, you should be sure there is no way for exhaust gases to enter the vehicle interior and endanger people or animals. Close windows, doors and other openings in the vehi- cle that, if open, might permit exhaust gases to enter the vehicle.

DANGER

The generator engine releases DEADLY carbon

!monoxide gas through its exhaust system. This dangerous gas, if breathed in sufficient concen- trations, can cause unconsciousness or even death. Never operate the generator set with the vehicle inside any garage or other enclosed area. DO NOT OPERATE THE GENERATOR IF THE EXHAUST SYSTEM IS LEAKING OR HAS BEEN DAMAGED. SYMPTOMS OF CARBON MONOX- IDE POISONING ARE (a) inability to think coher- ently, (b) nausea, (c) vomiting, (d) twitching muscles, (e) throbbing temples, (f) dizziness, (g) headaches, (h) weakness, and (i) sleepiness. IF YOU EXPERIENCE ANY OF THESE SYMPTOMS, MOVE INTO FRESH AIR IMMEDIATELY. IF SYMP- TOMS PERSIST, GET MEDICAL HELP. Shut down the generator and do not operate it until it has been inspected and repaired.

Any attempt to crank or start the engine before

!you have properly serviced it with the recom- mended oil may result in an engine failure.

DANGER

Never sleep in the vehicle while the genset is

!running unless the vehicle has a working carbon monoxide detector. The exhaust system must be installed in accordance with the genset installa- tion manual. Make sure there is ample fresh air when operating the genset in a confined area.
