INTRODUCTION Thank you for purchasing this model of the GUARDIAN® product line by Generac Power Systems, Inc. This model is a compact, high performance, air-cooled, engine driven generator designed to supply electrical power to operate electrical loads where no utility power is available or in place of utility due to a power outage.
IMPORTANT SAFETY INSTRUCTIONS Commercial-Industrial-Residential Portable Generator System THESE INSTRUCTIONS – The manufacturer suggests that these rules for safe operation be copied and posted near the unit's SAVE installation site. Safety should be stressed to all operators and potential operators of this equipment. • Never start or stop the unit with electrical loads connected to receptacles AND with connected devices turned ON.
IMPORTANT SAFETY INSTRUCTIONS Commercial-Industrial-Residential Portable Generator System ELECTRICAL HAZARDS EXPLOSION HAZARDS • All generators covered by this manual produce dangerous electrical voltages and can cause fatal electrical shock. Utility power delivers extremely high and dangerous voltages as does the generator when it is in operation. Avoid contact with bare wires, terminals, connections, etc., while the unit is running.
Section 1 – General Information Commercial-Industrial-Residential Portable Generator System 1.1 UNPACKING 1.2 ASSEMBLY • Set the palleted carton on a rigid flat surface. • Remove staples along bottom of carton that fasten carton to pallet. Open carton from top. The generator requires some assembly prior to using it. If problems arise when assembling the generator, please call the Generator Helpline at 1-800-333-1322. • Remove all packaging material. 1.2.
1.2.3 BATTERY CONNECTION Figure 3 - Battery Connections • The battery shipped with the generator has been provided fully charged. Caution must be taken when connecting the battery. NOTE: A battery may lose some of it’s charge when not in use for prolonged periods of time. • Cut the tie wrap cable holding the RED and BLACK battery cables to the stator. • Connect the RED battery cable to the battery Positive terminal (+).
Section 2 – Operation Commercial-Industrial-Residential Portable Generator System OPERATION 2.1 KNOW THE GENERATOR Read the Owner’s Manual and Safety Rules before operating this generator.
Section 2 – Operation Commercial-Industrial-Residential Portable Generator System 14) Start/Run/Stop Switch – Controls the operation of the generator. 15) Oil Fill – Use this point to add oil to engine. 16) Fuse - 10 Amp (Located at rear of control panel) – Protects the DC control circuit from overload. If this fuse element has melted open the engine will not be able to crank and start. A GFCI receptacle does NOT protect against circuit overloads, short circuits, or shocks.
Section 2 – Operation Commercial-Industrial-Residential Portable Generator System Figure 9 - 120 VAC, 30 Amp Receptacle 2.2.5 12 VOLT DC, 10 AMP RECEPTACLE This receptacle allows you to recharge a 12 Volt automotive or utility style storage battery with the battery charge cables provided. This receptacle can not recharge 6 Volt batteries and can not be used to crank an engine having a discharged battery. See the section "Charging a Battery" (page 13) before attempting to recharge a battery.
Section 2 – Operation Commercial-Industrial-Residential Portable Generator System 2.3 HOW TO USE THE GENERATOR 2.3.2 CONNECTING ELECTRICAL LOADS If you have any problems operating your generator, please call the generator helpline at 1-800-333-1322. DO NOT connect 240 Volt loads to 120 Volt receptacles. DO NOT connect 3-phase loads to the generator. DO NOT connect 50 Hz loads to the generator. 2.3.1 GROUNDING THE GENERATOR • Let engine stabilize and warm up for a few minutes after starting.

Section 2 – Operation Commercial-Industrial-Residential Portable Generator System 2.6.2 ADDING GASOLINE ------------- WARNING ------------ WARNING: Never fill fuel tank indoors. Never fill fuel tank when engine is running or hot. DO NOT light a cigarette or smoke when filling the fuel tank. Caution: Do not overfill the fuel tank. Always leave room for fuel expansion. • Use regular UNLEADED gasoline with the generator engine. Do not use premium gasoline. Do not mix oil with gasoline.
Section 2 – Operation Commercial-Industrial-Residential Portable Generator System • Move engine CHOKE knob outward to “Full Choke” position. Figure 17 - Full Choke Position 2.9 AUTOMATIC IDLE CONTROL This feature is designed to greatly improve fuel economy. When this switch is turned “On,” the engine will only run at its normal fast governed engine speed when electrical load is connected. When the load is removed, the engine will run at a reduced speed of 2100 RPM.
Section 2 – Operation Commercial-Industrial-Residential Portable Generator System 2.12 CHARGING A BATTERY DANGER! Storage batteries give off explosive hydrogen gas while recharging. An explosive mixture will remain around the battery for a long time after it has been charged. The slightest spark can ignite the hydrogen and cause an explosion. Such an explosion can shatter the battery and cause blindness or other serious injury.
Section 3 — Maintenance Commercial-Industrial-Residential Portable Generator System 3.1 MAINTENANCE SCHEDULE Follow the calendar intervals. More frequent service is required when operating in adverse conditions noted below.
Section 3 — Maintenance Commercial-Industrial-Residential Portable Generator System 3.3.3 ENGINE MAINTENANCE 3.3 GENERAL RECOMMENDATIONS The warranty of the generator does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, the operator must maintain the generator as instructed in this manual. DANGER! When working on the generator, always disconnect negative cable from battery.
3.3.6 REPLACING THE SPARK PLUG To clean or replace foam pre-cleaner: Use Champion RC14YC spark plug or equivalent. The correct air gap is 1.01 mm (0.040 in.). Replace the plug once each year. This will help your engine start easier and run better. • Remove air cleaner cover, then foam pre-filter. 1. Stop the engine and pull the spark plug wire off of the spark plug. • Clean air cleaner cover before re-installing it. 2. Clean the area around the spark plug and remove it from the cylinder head.
Section 3 — Maintenance Commercial-Industrial-Residential Portable Generator System Figure 21 - Spark Arrestor To adjust valve clearance: • Loosen the rocker jam nut. Use an 10mm allen wrench to turn the pivot ball stud while checking clearance between the rocker arm and the valve stem with a feeler gauge. Correct clearance is 0.002-0.004 inch (0.05-0.1 mm). NOTE: You must hold the rocker arm jam nut in place as you turn the pivot ball stud.
Section 3 — Maintenance Commercial-Industrial-Residential Portable Generator System 3.7 GENERAL 3.9 OTHER STORAGE TIPS: The generator should be started at least once every seven days and be allowed to run at least 30 minutes. If this cannot be done and you must store the unit for more than 30 days, use the following information as a guide to prepare it for storage. • Do not store gasoline from one season to another.
