Refer to
on page 39 for information about which file and
gauge that RedMax recommends for your saw chain.
2. Apply the file gauge correctly on to the cutter. Refer
to the instruction supplied with the file gauge.
3. Move the file from the inner side of the cutting teeth
and out. Decrease the pressure on the pull stroke.
(Fig. 123)
4. Remove material from one side of all the cutting
teeth.
5. Turn the product around and remove material on the
other side.
6. Make sure that all cutting teeth are the same length.
General information about how to adjust the
depth gauge setting
The depth gauge setting (C) decreases when you

To adjust the tension of the saw chain
WARNING:
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. 125)
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. 126)
5. Tighten the bar nuts using the wrench and lift the
front of the guide bar at the same time.
6. Make sure you can pull the saw chain around freely
by hand and that it does not hang from the guide
bar. (Fig. 127)

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.
2. If the saw chain lubrication is correct, you see a clear
line of oil on the surface after 1 minute. (Fig. 128)
3. If the saw chain lubrication does not operate
correctly, do a check of the guide bar. Refer to
To do a check of the guide bar on page 36 for
instructions. Speak to your servicing dealer if the
maintenance steps does not help.
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. 129)
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.
