REMOVING A UNIT FROM STORAGE
1.
Remove spark plug.
2.
Pull starter rope briskly to clear excess oil from com-
bustion chamber.
3.
Clean and gap spark plug or install a new spark plug
with proper gap.
4.
Prepare unit for operation.
5.
Fill fuel tank with proper fuel / oil mixture. See
FUEL
AND LUBRICATION
Section.
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.
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:
1.
Move the STOP switch down.
NOTE:
It is not necessary to remove the saw chain to
lubricate the guide bar sprocket tip. Lubrication can be
done on the job.
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
- 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.

WARNING
:
Always wear protective gloves dur-
ing maintenance operations. Do not carry out
maintenance when the engine is hot.
Fig. 24
WARNING
:
A sharp chain produces well-
defined chips. When your chain starts to produce
sawdust, it is time to sharpen.

Fig. 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.
