PUTTING THE SAW BACK INTO OPERATION
1.
Remove spark plug.
2.
Clean the spark plug and check that the electrode
gap is correct.
3.
Prepare unit for operation.
4.
Fill fuel tank with proper fuel / oil mixture. See
FUEL
AND LUBRICATION
Section.
• CHAIN BAR MAINTENANCE
Regular lubrication of the chain bar (guide rail for the
chain and teeth) is essential. The chain bar needs the
maintenance described in the following section in order
for the saw to work at an optimum level of performance.
TOOLS FOR LUBRICATION:
The Lube Gun (optional) is recommended for applying
grease to the guide bar sprocket tip. The Lube Gun is
equipped with a needle nose tip which is necessary for the
efficient application of grease to the sprocket tip.
TO LUBRICATE SPROCKET TIP:
Lubrication of the sprocket tip is recommended after 10
hours of use or once a week, which ever occurs first.
Always thoroughly clean guide bar sprocket tip before
lubrication.
NOTE: The saw chain does not have to be removed in
order to lubricate the teeth of the chain bar. Lubrication
is possible during work, with the engine switched off.
1.
Move the STOP switch down.
2.
Clean the guide bar sprocket tip.
3.
Using the Lube Gun (optional), insert needle nose
into the lubrication hole and inject grease until it
appears at outside edge of sprocket tip (Fig .23).
4.
Rotate saw chain by hand. Repeat lubrication proce-
dure until the entire sprocket tip has been greased.
GUIDE BAR MAINTENANCE:
Most guide bar problems can be prevented merely by
keeping the chain saw well maintained.
Insufficient guide bar lubrication and operating the saw
with chain that is TOO TIGHT will contribute to rapid bar
wear.
To help minimize bar wear, the following guide bar main-
tenance procedures are recommended.
CHAIN SHARPENING:
Chain sharpening requires special tools to ensure that
cutters are sharpened at the correct angle and depth.
For the inexperienced chain saw user, we recommend
that the saw chain be professionally sharpened by the
nearest professional Service Center. If you feel
comfortable sharpening your own saw chain, special
tools are available from the professional Service Center.
CHAIN SHARPENING
- The pitch of the chain (Fig. 24)
is 3/8” LoPro x .050”.
Sharpen the chain using protective gloves and a round file
of ø3/16” (4.8mm).
Always sharpen the cutters only with outward strokes (Fig.
25) observing the values given in Fig. 24.
After sharpening, the cutting links must all have the same
width and length.
After every 3-4 times the cutters have been sharpened
you need to check the height of the depth gauges and, if
necessary, lower them using the flat file and template sup-
plied optional, then round off the front corner. (Fig. 26)
GUIDE BAR
- The bar should be reversed every 8 work-
ing hours to ensure uniform wear.
Keep the bar groove and lubrication hole clean using the
bar groove cleaner supplied optional. (Fig. 27)
Check the bar rails frequently for wear and, if necessary,
remove the burs and square-up the rails using the flat file.
(Fig. 28)
CAUTION
: The sprocket tip on your new saw has
been pre-lubricated at the factory. Failure to
lubricate the guide bar sprocket tip as explained
below will result in poor performance and seizure,
voiding the manufacturer’s warranty.
WARNING:
Wear heavy duty work gloves
when handling the bar and chain.
23
WARNING
:
Always wear protective gloves dur-
ing maintenance operations. Do not carry out
maintenance when the engine is hot.
WARNING
:
A sharp chain produces well-
defined chips. When your chain starts to produce
sawdust, it is time to sharpen.
26
25
WARNING
:
Proper adjustment of the depth
gauge is as important as proper sharpening of
the chain.
WARNING
:
Never mount a new chain on a
worn sprocket or self-aligning ring.
