What is the best way to cut weeds and grass using my string trimmer?
- Keep your string trimmer tilted toward the area being cut
- Pass the unit from left to right (if using a curved shaft string trimmer) and from right to left (if using a straight shaft string trimmer). By following these directional cutting paths, you will avoid having debris and grass clippings from being directed back at yourself.
- Use the top of the line to do the cutting. Do not force the string head into uncut grass; this could cause the trimmer to bog down.
- Avoid trees, shrubs wire and picket fences.
What is the correct fuel mixture to use with my 2 cycle engine RYOBI Outdoor Product?
Your 2-cycle engine requires pre-mixing gasoline and 2-cycle lubricant. Pre-mix unleaded gasoline and 2-cycle engine lubricant in a clean gas container. DO NOT mix quantities larger than usable in a 30-day period. Do not use automotive lubricant or 2-cycle outboard lubricant. We recommend using a RYOBI/Homelite premium 2-cycle oil or a PowerCare 2-cycle oil.
Filling your tank:
- Clean surface around fuel cap to prevent contamination
- Loosen fuel cap slowly. Rest the cap on a clean surface.
- Carefully pour fuel into the tank. Avoid spillage.
- Prior to replacing the fuel cap, clean around the gasket.
- Immediately replace fuel cap and hand tighten. Wipe up any fuel spillage
Note: it is normal for smoke to be emitted from a new engine after fist use.
