• Sharpen one tooth of the saw blade to the right and
the next tooth to the left, see the illustration.
15˚
Note: Sharpen the edges of the teeth with a flat file if
the blade is heavily worn. Continue to sharpen with a
round file.
• Sharpen all edges equally to keep the blade
balanced.
• Adjust the blade set to 1 mm with the recommended
setting tool. Refer to the instructions that come with
the blade.
WARNING: Always discard a blade that is
damaged. Do not try to make a bent or
twisted blade straight and use it again.
To examine the spark plug
CAUTION:
Always use the recommended
spark plug type. Incorrect spark plug type
can cause damage to the product.
• Examine the spark plug if the engine is low on
power, is not easy to start or does not operate
correctly at idle speed.
• To decrease the risk of unwanted material on the
spark plug electrodes, obey these instructions:
a) Make sure that the idle speed is correctly
adjusted.
b) Make sure that the fuel mixture is correct.
c) Make sure that the air filter is clean.
• If the spark plug is dirty, clean it and make sure that
the electrode gap is correct, refer to
Technical data
on page 28
.
• Replace the spark plug if it is necessary.
To adjust the product for cold
environments
If the temperature is 5° or colder, adjustments are
necessary to prevent operation problems.
• Attach the air duct as shown in the illustration. Make
sure that the arrow points in the direction of the
winter mode symbol.
• Replace the air filter cover with the winter mode air
filter cover.
• If you operate the product in snow, attach a cover on
top of the starter.
• For 545FXT, make sure that the wire is lubricated
when you operate the product in cold environments.
• At temperatures of more than 5°, change back to the
regular air filter cover. Remove the cover on top of
the starter and adjust the air duct back to the initial
position. Make sure that the arrow points in the
direction of the summer mode symbol.
CAUTION:
Do not operate the product at
temperatures of more than than 5° if it is
adjusted for winter mode. The engine
becomes too hot and can be damaged.
