To adjust the tension of the saw chain
WARNING: A saw chain with an incorrect
tension can come loose from the guide bar
and cause serious injury or death.
A saw chain becomes longer when you use it. Adjust the
saw chain regularly.
1. Loosen the bar nuts that hold the clutch cover/chain
brake. Use a wrench. (Fig. 128)
Note: Some models have only one bar nut.
2. Tighten the bar nuts by hand as tightly as you can.
3. Lift the front of the guide bar and turn the chain
tensioning screw. Use a wrench.
4. Tighten the saw chain until it is tight against the
guide bar but still can move easily. (Fig. 129)
5. Tighten the bar nuts using the wrench and lift the
front of the guide bar at the same time.

lubrication
1. Start the product and let it operate at ¾ throttle. Hold
the bar approximately 20 cm/8 in above a surface of
light color.

To do a check of the spur sprocket
The clutch drum has a spur sprocket that is welded on
the clutch drum.

Regularly do a visual check of the degree of wear on
the spur sprocket. Replace the clutch drum with the
spur sprocket if there is too much wear.
To lubricate the needle bearing
1. Pull the front hand guard rearward to disengage the
chain brake.
2. Loosen the bar nuts and remove the clutch cover.
Note: Some models have only one bar nut.
3. Put the product on a stable surface with the clutch
drum up.
4. Lubricate the needle bearing with a grease gun. Use
engine oil or a bearing grease of high quality. (Fig.

To examine the cutting equipment
1. Make sure that there are no cracks in rivets and links
and that no rivets are loose. Replace if it is
necessary. (Fig. 134)
2. Make sure that the saw chain is easy to bend.
Replace the saw chain if it is rigid.
3. Compare the saw chain with a new saw chain to
examine if the rivets and links are worn.
4. Replace the saw chain when the longest part of the
cutting tooth is less than 4 mm/0.16 in. Also replace
the saw chain if there are cracks on the cutters. (Fig.
135)
To do a check of the guide bar
1. Make sure that the oil channel is not blocked. Clean
