chapter before you clean, repair or do
maintenance on the product.
Maintenance schedule
Make sure that you obey the maintenance schedule.
The intervals are calculated from daily use of the
product. The intervals are different if you do not use the
product each day. Only do the maintenance work that is
found in this manual. Speak to an approved service
center about other maintenance work not found in this
manual.
Daily maintenance
• Clean the external surfaces.
• Make sure that the trigger lockout and trigger work
correctly.
• Clean the chain brake and make sure that it
operates correctly.
• Examine the chain catcher for damage. Replace the
chain catcher if it is damaged.
• Turn the guide bar daily for more equal wear.
• Make sure that the lubrication hole in the guide bar is
not clogged.
• Remove saw dust and other unwanted material from
below the sprocket cover.
• Clean the guide bar groove.
(Fig. 44)
• Make sure that the guide bar and saw chain get
sufficient oil.
• Examine the saw chain for:
• a crack in the rivets and links.
• irregularly worn rivets and links.
• the correct tension.
• burrs on the chain drive links.
If necessary, replace the saw chain.
• Sharpen the saw chain. See
chain on page 17 .
• Examine the drive sprocket for too much wear and
replace if necessary.
(Fig. 45)
• Clean the air intake of the motor housing.
• Make sure that the nuts and screws are tight.
• Make sure that the power switch works correctly.
To sharpen the saw chain
The cutter
The cutter is the cutting part of the saw chain and has a
cutting tooth (A) and depth gauge (B). The cutting depth
of the cutter is made by the difference in height between
the two, the depth gauge setting (C).

Maintenance

To sharpen the saw
(Fig. 46)
Make sure to correctly sharpen the cutting teeth by
using four important criteria:
• File angle
(Fig. 47)
• Cutting angle
(Fig. 48)
• File position
(Fig. 49)
• Round file diameter
(Fig. 50)
To sharpen the cutting teeth
Use a round file and a file gauge to sharpen the cutting

teeth. See
on page 21 for information on the recommended
dimension of the file and gauge for the saw chain
installed on your product.
(Fig. 51)
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
file on the teeth.
4. Use the file to keep all teeth the same length.
Replace a worn saw chain when the length of the
cutting teeth decreases to 4 mm (5/32 in).
To adjust the depth gauge setting

gauge. See
After you sharpen the cutting tooth (A), the adjustment
of the depth gauge (C) will decrease. To keep the best
cutting performance, use a file on the depth gauge (B) to
get the recommended depth gauge adjustment. See
Guide bar and saw chain combinations on page 20 to
find the correct depth gauge adjustment for your chain.
(Fig. 52)
Note: These recommendations are for when the length
of the cutting teeth has not been significantly decreased.
Use a flat file and depth gauge tool to adjust the depth
gauge.
1. Put the depth gauge tool above the saw chain. More
information about operation can be found on the
package of the depth gauge tool. (Fig. 53)
2. Use the flat file on the top of the depth gauge that
extends through the depth gauge tool. The depth
gauge is adjusted correctly when there is no
