Hose Assembly

Used as an alternative to the nozzle to vacuum yard waste such as leaves or pine needles in hard to reach places.

Hose Handle

Used to guide hose assembly when vacuuming.

Nozzle/Hose Vac Handle

The nozzle/hose vac handle is located on top of the nozzle and it is used to regulate the vacuum between the nozzle and the hose assembly.

GAS AND OIL FILL-UP

Oil (one 20-oz. bottle shipped with unit)

Only use high quality detergent oil rated with API service classification SF, SG, or SH. Select the oil’s SAE viscosity grade according to the expected operating temperature. Follow the chart below.

Colder	32°F	Warmer
5W30	SAE 30
	Oil Viscosity Chart

NOTE: Although multi-viscosity oils (5W30, 10W30, etc.) improve starting in cold weather, they will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible engine damage from running low on oil.

•Remove oil fill dipstick.

•With the Yard Vacuum on level ground, use a funnel to fill engine with oil to FULL mark on dipstick. Capacity is approximately 20 oz. Be careful not to overfill. Overfilling will cause the engine to smoke profusely and will result in poor engine performance. The oil bottle packaged with your Yard Vacuum contains 20 oz. of oil.

•Check the oil level making certain not to rub the dipstick along the inside walls of the oil fill tube. This would result in a false dipstick reading. Refill to FULL mark on dipstick, if necessary. Replace dipstick and tighten.

•Check oil level three times prior to starting engine to be certain you’ve gotten an accurate dipstick

reading. Running the engine with too little oil can result in permanent engine damage.

Gasoline

•Remove fuel cap from the fuel tank.

•Make sure the container from which you will pour the gasoline is clean and free from rust or foreign particles. Never use gasoline that may be stale from long periods of storage in its container. Gasoline that has been sitting for any period longer than four weeks should be considered stale.

•Fill fuel tank with clean, fresh, unleaded regular, unleaded premium or reformulated automotive gasoline only. DO NOT use Ethyl or high octane gasoline. Do not use gasoline containing METHANOL. Replace fuel cap.

•To avoid engine problems, the fuel system should be emptied before storage for 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. See STORAGE section for additional information.

WARNING: Use extreme care when handling gasoline. Gasoline is extremely flammable and the vapors are explosive. Never fuel machine indoors or while the engine is hot or running. Extinguish cigarettes, cigars, pipes, and other sources of ignition.

•Check the fuel level periodically to avoid running out of gasoline while operating the Yard Vacuum. If the unit runs out of gas as it is chipping, it may be necessary to unclog the unit before it can be restarted. Refer to SERVICE AND ADJUSTMENT section.

TO STOP ENGINE

•Move throttle control lever to STOP or OFF position.

•Disconnect spark plug wire and ground it to the post to prevent accidental starting while the equipment is unattended.

WARNING: When moving throttle control lever, be careful of heated surfaces and sharp edges on muffler guard.

TO START ENGINE

1.Attach spark plug wire and rubber boot to spark plug.

2.The bag/chute switch button must be fully depressed by the tip of front tab on bag handle or blower chute for engine to start.

3.Make sure bag/chute switch wire is connected to engine and grounded to mounting bracket.

4.Gas tank should be filled 3/4 to full before start- ing.

5.Move throttle control to START/RUN position. See Figure 8.

6.Move the choke control toward the throttle control to choke the engine’s carburetor. (A warm engine may not require choking.) See Figure 8.
