1. If the product is hard to start or operate, examine the
spark plug for unwanted materials. To decrease the
risk of unwanted material on the spark plug
electrodes:
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.
2. Clean the spark plug if it is dirty. Make sure that the
electrode gap is correct.(Fig. 71 )
3. Replace the spark plug when it is necessary.

To clean the air filter

1. Remove the air filter cover and remove the air filter.
(Fig. 72 )
2. Clean the air filter with warm soap water. Make sure
that the air filter is dry before you install it.
3. Replace the air filter if it is too dirty to fully clean it.
Always replace a damaged air filter.

To sharpen the saw chain

The cutter
The cutting part of the saw chain is called the cutter and
consists of a cutting tooth (A) and the depth gauge (B).
The cutters cutting depth is determined by the difference
in height between the two, the depth gauge setting (C).
(Fig. 73 )
When you sharpen a cutting tooth there are four
important factors to remember:
• Filing angle.
(Fig. 74 )
• Cutting angle.
(Fig. 75 )
• File position.
(Fig. 76 )
• Round file diameter.
(Fig. 77 )

To sharpen the cutting teeth

Use a round file and a file gauge to sharpen the cutting
teeth. See Saw chain filing and saw chain combinations
on page 23 for information on the recommended
dimension of the file and gauge for the saw chain
installed on your product.
(Fig. 78 )
1. Make sure that the saw chain has the correct
tension. A chain without the correct tension moves to
one side does and not sharpen correctly.
2. Use the file on all the teeth on one side. Then use
the file on the cutting teeth from the inner face and
decrease the pressure in the reverse direction.

3. Turn the product on the opposite side and use the
4. Use the file to keep all teeth the same length.
To adjust the depth gauge setting
Sharpen the cutting teeth before you adjust the depth
gauge setting. See
20 . When you sharpen the cutting tooth (A), the depth
gauge setting (C) will decrease. To maintain optimal
cutting performance, the depth gauge (B) has to be filed
down to achieve the recommended depth gauge setting.
See
page 23 to find the correct depth gauge setting for your
particular chain.
(Fig. 79 )
(Fig. 80 )
Note: This recommendation assumes that the length of
the cutting teeth is not reduced excessively.
Use a flat file and depth gauge tool to adjust the depth
gauge.
1. Put the depth gauge tool above the saw chain.
2. Use the flat file to file off the tip of the depth gauge
To tension the saw chain
Note: Check the tension of a new saw chain frequently
during its running-in period.
1. Loosen the guide bar nuts that hold the sprocket
2. Tighten the guide bar nuts by hand as tight as you
3. Lift the top of the guide bar and extend the saw
4. Tighten the guide bar nuts using the combination
5. Make sure that you can pull the saw chain round
file on the teeth.
Replace a worn saw chain when the length of the
cutting teeth decreases to 4 mm (5/32 in).
