Essential Lawn Mower Maintenance
Regular maintenance is crucial for the longevity and performance of your Stihl RM 248 T. Here are some key areas to focus on:
1. Blade Care: Sharpening and Replacement
The sharpness of your mower blades directly impacts the quality of your lawn cut. Sharp blades make clean cuts, promoting healthy grass growth. Dull blades tear the grass, leaving ragged edges that can turn brown and increase susceptibility to disease. The manual will guide you on how to safely remove, sharpen, and reattach the blades. A general rule of thumb is to sharpen blades at least once a season, or more frequently if you encounter tough conditions or notice a degradation in cut quality. Always ensure the engine is off and the spark plug is disconnected before performing any blade work.
2. Engine Maintenance
Like any petrol engine, the one on your RM 248 T requires regular attention. This typically includes:
- Oil Changes: Refer to your manual for the recommended oil type and change interval. Clean oil is vital for engine lubrication and cooling.
- Air Filter: A clogged air filter restricts airflow to the engine, reducing efficiency and power. Clean or replace it as per the manual's instructions, usually annually or as needed.
- Spark Plug: Ensure the spark plug is clean and correctly gapped. A fouled or worn spark plug can lead to starting issues and poor performance.
- Fuel: Always use fresh, clean petrol. Storing fuel for extended periods can lead to degradation. If you accidentally put diesel in a petrol mower, do NOT start the engine. The tank must be completely emptied and refilled with the correct fuel.
3. Cleaning and Storage
After each use, it's good practice to clean grass clippings and debris from the mower deck and engine. This prevents rust and corrosion, and ensures components function correctly. For winter storage, ensure the fuel tank is either emptied or treated with a fuel stabiliser. Store the mower in a dry, sheltered location. The foldable handlebars of the RM 248 T make it particularly convenient for storage.
Frequently Asked Questions (FAQs)
Here are some common queries regarding lawn mower operation and maintenance, with answers relevant to your Stihl RM 248 T:
- How do I know when to sharpen the blades of my lawn mower?
- Sharp blades make clean cuts, leaving the grass green. Dull blades tear the grass, resulting in a brown, ragged appearance. If you notice this, it's time to sharpen or replace the blades.
- What is mulching?
- Mulching is a feature on some mowers where finely shredded grass clippings are returned to the lawn. These clippings act as a natural fertiliser and help retain moisture in the soil.
- I accidentally put diesel in my petrol lawn mower, what should I do?
- Immediately stop and do not attempt to start the mower. The fuel tank must be completely drained of the diesel and refilled with the correct petrol. This is the only safe solution.
- What is the best length for my grass?
- To prevent the grass from drying out, avoid cutting it too short. It's better to mow more frequently, maintaining an optimal length between 3 and 4 centimetres. This promotes healthier growth.
- Can I mow grass when it's wet?
- While possible, it's not advisable. Wet grass clumps together, leading to an uneven cut and potentially clogging the mower. It also increases the risk of spreading lawn diseases.
- What is the right moment to mow my lawn?
- The best time for mowing is generally from March to October, once or twice a week depending on growth. Mow in the late afternoon to allow the grass to recover before the heat of the day or potential overnight dew.
- At what lawn surface do I choose an electric mower and at which surface a petrol mower?
- For lawn areas up to 300m², a battery-powered mower is often suitable. For larger areas, especially those exceeding 300m², a petrol mower like the RM 248 T is recommended due to its power and longer run time.
- Can I let a robot mower work in the night?
- It is generally not recommended to operate robot mowers at night. Nocturnal animals, such as hedgehogs, can be at risk as they may not be able to escape the mower in time, potentially leading to injury or death.
