Gasoline
Do not use unapproved gasolines, such as E85. Do not mix oil in gasoline
or modify engine to run on alternate fuels. This will damage the engine
components and void the engine warranty.
Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane/87 AKI (91 RON).
• Gasoline with up to 10% ethanol (gasohol) is acceptable.
Refuel in a well-ventilated area with the engine stopped. If the engine has been
running, allow it to cool first. Never refuel the engine inside a building where
gasoline fumes may reach flames or sparks.
Gasoline is highly flammable and explosive, and you can be burned or
seriously injured when refueling. Stop engine and keep heat, sparks, and
flame away. Refuel only outdoors. Wipe up spills immediately.
If your equipment will be used on an infrequent or intermittent basis, please
refer to the Off Season Storage section for additional information regarding fuel
deterioration.
NOTE: Fuel can damage paint and some types of plastic. Be careful not to spill fuel
when filling your fuel tank.
Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid getting
dirt or water in the fuel tank.
1. Remove the fuel tank cap.
2. Fill the fuel tank with fuel. To allow for expansion of the fuel, do not fill
above the bottom of the fuel tank neck. Do not overfill. Wipe up spilled fuel
before starting the engine.
3. Install the fuel tank cap and tighten it until it clicks.
4. Move yard vaccum at least 10 feet away from the fuel container/source and
site before starting the engine.
NOTE: 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 discharge area before it can be restarted. Refer to SERVICE
AND MAINTENANCE section.
Starting The Engine
Be sure no one other than the operator is standing near the yard vaccum
while starting engine or operating vacuum. Never run engine indoors
or in enclosed, poorly ventilated areas. Engine exhaust contains carbon
monoxide, an odorless and deadly gas. Keep hands, feet, hair and loose
clothing away from any moving parts on engine and yard vacuum.
IMPORTANT: 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. See Figure 13.
NOTE: Make sure bag/chute switch wire is connected to engine and grounded to
mounting bracket.
