FAQs

What type of petrol should I use?

Use fresh, unleaded petrol with a minimum octane rating of 87. Always use fresh fuel to prevent engine issues.

How often should I change the engine oil?

It is recommended to change the engine oil after the first 5 hours of operation and then every 50-100 hours of use or at least once per mowing season.

Can this mower be used for mulching?

Yes, the Einhell GC-PM 51/3 S HW-E Li features a mulching function. You can switch between collecting grass and mulching by using the appropriate plug.

What is the recommended lawn size for this mower?

This mower is recommended for lawns up to approximately 1,800 m².

How do I engage the self-propelled feature?

The self-propelled feature is typically engaged by a lever or control bar on the handle that, when squeezed, drives the rear wheels.

Is assembly required upon delivery?

Some assembly is required, primarily for attaching the handle sections and connecting cables. Refer to the user manual for detailed instructions.

What is the purpose of the electric start?

The electric start uses a battery to ignite the engine with the push of a button, eliminating the need for a manual pull-start cord and making starting faster and easier.

Troubleshooting

Mower won't start

Ensure the fuel tank is full of fresh petrol and the oil level is correct. Check that the spark plug wire is securely attached. Ensure the battery for the electric start is charged. If using the pull cord, check for obstructions and ensure the choke is set correctly for a cold start.

Engine runs rough or stalls

Check the air filter for clogs and clean or replace it if necessary. Ensure you are using fresh fuel. Clean the spark plug or replace it if it looks fouled. Verify the fuel cap vent is not blocked.

Poor cutting performance

Ensure the cutting blade is sharp and properly attached. Check that the cutting deck is clear of debris. Adjust the cutting height to a higher setting if the grass is very long or dense. Ensure the self-propelled system is engaged if needed for consistent speed.

Grass catcher not filling efficiently

Ensure the grass catcher is properly attached and not overfilled. Check for blockages in the discharge chute. If using the mulching function, ensure the mulching plug is removed.

Excessive vibration

Stop the mower immediately and inspect the cutting blade for damage or imbalance. Ensure the blade is securely fastened. Check for any debris lodged in the mower deck.

Setup, Compatibility & Care

Initial Setup:

  1. Unpacking: Carefully unpack all components and check for any damage.
  2. Handle Assembly: Attach the handle sections, ensuring all bolts are tightened securely. Adjust the handle height to your preference.
  3. Cable Management: Secure control cables to the handle frame using the provided clips.
  4. Fluid Check: Before first use, check the engine oil level and add appropriate oil if necessary. Fill the fuel tank with fresh, unleaded petrol. The mower comes with a battery charger for the electric start system; ensure the battery is charged.

Compatibility:

  • Fuel: Use fresh, unleaded petrol (minimum 87 octane).
  • Oil: Use SAE 30 or 10W-30 engine oil suitable for four-stroke engines.
  • Battery: Compatible with the included electric start battery and charger.

Care and Maintenance:

  • After Each Use: Clean the mower deck, especially the underside, to remove grass clippings. Empty the grass catcher.
  • Engine Maintenance: Regularly check the oil level. Change the oil after the first 5 hours of operation and then every 50-100 hours or annually. Clean or replace the air filter as recommended in the user manual.
  • Spark Plug: Inspect and clean the spark plug annually, or replace it if worn.
  • Blade Maintenance: Sharpen or replace the cutting blade annually, or more often if it becomes dull or damaged. Ensure it is balanced after sharpening.
  • Storage: For long-term storage (e.g., over winter), drain the fuel tank or use a fuel stabilizer. Clean the mower thoroughly.
