Center Bolt 40Nm.min, 50Nm.max. To ensure safe operation of your unit. All nuts and bolts must be checked periodically for
correct tightness. After prolonged use, especially in sandy soil conditions, the blade will become worn and lose some of the
original shape. Cutting efficiently will be reduced and the blade should be replaced. Replace with an approved factory
replacement blade only. Possible damage resulting from blade unbalance is not the responsibility of the manufacturer.

When you change the blade, use the original type marked on the blade (Cobra Part 263001330) (to order the blade, please
contact your local dealer)

10.4 ENGINE
Refer to the separate engine manual for engine maintenance instructions.
Maintain engine oil as instructed in the separate engine manual packed with your unit.
Read and follow the engine instructions carefully.
Service the air filter as per the separate engine manual. Clean every few hours under extremely dusty conditions. Poor engine
performance and flooding usually indicates that the air filter requires attention. To service the air filter, refer to the separate
engine manual packed with your mower. The spark plug should be cleaned and the gap reset annually. Spark plug replacement
is recommended at the start of each mowing season. Check the engine manual for the correct plug type and gap specifications.
Clean the engine regularly with a cloth or brush. Keep the cooling system (blower housing area) clean to permit proper air
circulation, which is essential to engine performance. Be certain to remove all grass, dirt and combustible debris from the muffler
area.
11. STORAGE INSTRUCTIONS (OFF SEASON)
The following steps should be taken to prepare the lawn mower for storage at the end of the mowing season.
1. Drain the fuel from the engine by running the engine until it stops.
a) Start the engine and let it run until it has used up all remaining petrol and stalls.
b) Remove the spark plug. Use an oilcan to fill approx. 20 ml oil into the combustion chamber. Operate the starter to evenly
distribute the oil in the combustion chamber. Replace the spark plug.
2. Clean and grease the lawnmower carefully as described above under “Lubrication”.
3. Slightly grease the cutter to avoid corrosion.
4. Store the lawnmower in a dry, clean and frost-protected place.
CAUTION! The engine must have completely cooled down before storing the lawnmower.
NOTE: - When storing any type of power equipment in an unventilated or material storage shed,
-Care should be taken to rust-proof the equipment. Using a light oil or silicone, coat the equipment, especially cables and all
moving parts.
- Be careful not to bend or kink cables.
