For the best and safest performance, service your lawn mower with care.
Replace with genuine parts
Replace worn or damaged parts for safety. Use only genuine Briggs & Stratton or Murray replacement parts and accessories when servicing or repairing.
Service the mower blade
Keep the mower blade sharp and clean. Inspect the blade for damage (e.g. bent, cracked, or worn), and replace the blade or sharpen it if required. When servicing the blades, be aware that even though the power source is switched off, the blades can still be moved.
Keep all nuts, bolts and screws tight to be sure the mower is in safe working conditions. Check the blade and engine mounting bolts for proper tightness frequently.
Change the oil
Be sure to change the oil once a season. This is not necessary when the engine has a specific feature that it only needs an occasional top-up.
Furthermore, check the grass collector frequently for wear or deterioration. Also check your air filter for any clogs or damage, and replace the filter if necessary. Lubricate your product as recommended in the manual.
