GENERAC Air-Cooled Generator GUARDIAN 20KW

WARNING: Risk of burns. Allow engine to cool before draining oil or coolant. Failure to do so could result in death or serious injury.

CAUTION: Engine damage. Verify proper type and quantity of engine oil prior to starting engine. Failure to do so could result in engine damage.

Check enclosure louvers for dirt and debris

Remove any shrubs or tall grasses within 3 ft of the intake and discharge louvers

Clean any debris inside the enclosure

Check lines and connections for fuel or oil leaks

The oil level should be checked daily when power outages necessitate running the generator for extended periods.

Run the generator for a cool-down period of approximately one minute

WARNING: Explosion. Do not dispose of batteries in a fire. Batteries are explosive. Electrolyte solution can cause burns and blindness. If electrolyte contacts skin or eyes, flush with water and seek immediate medical attention.

WARNING: Explosion. Batteries emit explosive gases while charging. Keep fire and spark away. Wear protective gear when working with batteries. Failure to do so could result in death or serious injury.

WARNING: Electrical shock. Disconnect battery ground terminal before working on battery or battery wires. Failure to do so could result in death or serious injury.

WARNING: Risk of burns. Batteries contain sulfuric acid and can cause severe chemical burns. Wear protective gear when working with batteries. Failure to do so could result in death or serious injury.

WARNING: Environmental Hazard. Always recycle batteries at an official recycling center in accordance with all local laws and regulations. Failure to do so could result in environmental damage, death or serious injury.

Always recycle batteries in accordance with local laws and regulations. Contact your local solid waste collection site or recycling facility to obtain information on local recycling processes.

Strictly observe the following precautions when working on batteries.

Lift the lid to gain access to the controller and press the OFF button to shut down the generator, then remove the front panel.

Remove the 7.5 amp fuse from the control panel.

Replace the Oil and Oil Filter. Change engine oil and filter after the first 25 hours of operation. In cold weather conditions (ambient below 40 °F / 4.4 °C), or if unit is operated continuously in hot weather conditions (ambient above 85 °F / 29.4 °C), change engine oil and filter every year or 100 hours of operation.

Did you start the engine and run it until it is thoroughly warmed up?

Did you press the control panel OFF button to shut down the engine?

Did you lift the lid and remove the front panel?

Did you pull the oil drain hose (A) free of its retaining clip?

Did you remove the cap from the hose and drain the oil into a suitable container?

Did you replace the cap after the oil has drained?

Did you reposition and secure the hose with the retaining clip?

Did you remove the old oil filter (B) by turning it counterclockwise?

Proceed as follows to check the spark plug(s) gap and replace the spark plug(s) as necessary:

With the generator OFF and the engine cool, lift the lid and remove the front panel

Clean the area around the base of the spark plug(s) to keep dirt and debris out of the engine

Remove the spark plug(s) and check the condition. Install a new plug(s) if the old plug(s) is worn or if reuse is questionable

Clean the plug(s) by scraping or washing with a wire brush and commercial solvent. Do not blast the plug(s) to clean
