Frequently Asked Questions - RZA 748 STIHL
What type of oil should I use for the STIHL RZA 748?
Use a high-quality SAE 30 or 10W-30 4-stroke engine oil. Change the oil every 25 hours of operation.
How do I adjust the cutting height on the RZA 748?
The cutting height is adjusted using a central lever. Move the lever to one of the 7 positions, ranging from 25 mm to 75 mm, to set the desired grass length.
Why won't my STIHL RZA 748 start?
Check the fuel level, ensure the spark plug is clean and properly connected, and verify that the air filter is not clogged. Also, make sure the blade brake clutch is engaged.
How often should I sharpen the blade?
Sharpen the blade at least once a season or after 25 hours of use. A dull blade tears grass, causing a brownish appearance. Always wear gloves and disconnect the spark plug before working on the blade.
Can I use the mulching feature without a special kit?
Yes, the STIHL RZA 748 comes with a mulching plug that blocks the discharge chute. Simply insert the plug to convert from bagging to mulching mode.
What is the correct fuel mixture?
The RZA 748 uses a 4-stroke engine, so it requires unleaded petrol only, not a fuel-oil mix. Use fresh, clean fuel with an octane rating of 87 or higher.
How do I clean the mower deck?
After each use, scrape off grass clippings from the underside of the deck. Use a hose with a nozzle to rinse, but avoid direct water on the engine. For deep cleaning, use a deck wash port if available.
Where can I find replacement parts?
Replacement parts such as blades, belts, and filters are available at authorized STIHL dealers. You can also order online from the STIHL official website or trusted retailers.
How do I store the mower for winter?
Drain the fuel tank and run the engine until it stops to avoid carburetor issues. Change the oil, clean the mower thoroughly, and store it in a dry place. Disconnect the spark plug and cover the mower.
What safety precautions should I take while mowing?
Always wear eye and ear protection, sturdy shoes, and long pants. Ensure children and pets are at a safe distance. Never mow in wet conditions, and disengage the blade before crossing gravel or paths.
