• If the spark plug is dirty, clean it and make sure that
the electrode gap is correct, refer to
on page 24 .
• Replace the spark plug if it is necessary.
WARNING: When you loosen and
tighten the locknut, there is a risk of
injury from the blade. You must always
make sure that the blade guard prevents
injury to your hand when you do this.

spark plug type. Incorrect spark plug type
can cause damage to the product.
