Cleaning or replacing the spark plug

Once the engine has cooled, pull off the spark plug boot with a twist. Remove the
spark plug using the socket spanner supplied.

Clean the plug with a wire brush.
3.
Using a feeler gauge, set the gap to 0.51mm.

0.43-0.51mm
Adding the oil
Refill with SAE 30 oil or equivalent, i.e. SAE 5W/30, SAE 10W/30). When the dipstick is
rested on the filler pipe, the oil level must be between the min. and max. marks on the
dipstick.
See 'Filling with engine oil'. Do not overfill.
Start the engine and allow it to run briefly.
Stop the engine, wait one minute and check the oil level. Top up if necessary.
Replacing the cutting blade
WARNING! USE GLOVES.
Before you remove the grass collection bag, stop the engine and wait until the
blade stops completely.
You will need garden gloves (not provided) and a spanner wrench to remove the
blade.
Always handle the blade with care; sharp edges could cause injury.
NEVER hold the blade directly by hand.
Renew your metal blade after 36 hours of mowing or after 2 years, whichever is sooner,
regardless of condition.
Regularly check your blade. If the cut of your grass is poor, the blade might be blunt.
Damaged blades not only result in a bad cut, they cause excessive vibration and
uneconomical running of the engine. If the blade has worn excessively and become pitted
and blunt, it should be replaced or sharpened.
Note: The blade carrier is designed to break under heavy blade impact to protect the
machine. If this happens, also replace the blade carrier. This can be purchased from
www.gardenservicecentre.co.uk.
To replace the blade, hold the blade and unscrew the blade bolt counterclockwise using a
spanner wrench. Remove the washer and the blade.
Inspect the blade adaptor for any signs of damage.
Fit a new blade, locate the blade on the two studs on the blade flange and then replace the
washer and bolts.
