BAR TIP SPROCKET LUBRICATION
NOTE:
It is not necessary to remove the chain in order
to lubricate the bar tip sprocket. Lubrication can be done
on the job.
Always clean the bar tip sprocket thoroughly prior opera-
tion.
Use a lube gun (not included in the kit) to lubricate the
bar tip sprocket.
Insert needle nose into the lubrication hole D and inject
oil until it appears at outside edge of sprocket.
(Fig.16)
Ensure the chain brake is deactivated. Rotate the chain
by hand.
Repeat the above described procedure until the sprocket
is lubricated entirely.
CLEANING THE GUIDE BAR GROOVE
Remove side cover, bar and chain.
Using a bar-groove cleaner (not included in the kit) or a
screwdriver, putty knife, wire brush or other similar tools,
clean residue from the bar groove. This will keep the oil
passages open and provide proper lubrication to the bar
and chain.
(Fig.17)
Reinstall the bar, chain (adjust tension) sprocket cover
and locking knob.
GUIDE BAR MAINTENANCE
Most guide bar problems can be prevented merely by
keeping the chain saw well maintained. Improper filing
and non-uniform cutter and depth gauge settings cause
most guide bar problems, resulting mainly in uneven bar
wear. As the bar wears unevenly, the rails widen, which
may cause chain clatter and difficulty in making straight
cuts. Insufficient guide bar lubrication and operating the
saw with a chain this is too tight will contribute to rapid
bar wear. To help minimize bar wear, the following guide
bar maintenance is recommended.
OIL PASSAGES
Oil passages on the bar should be cleaned to ensure
proper lubrication of the bar and chain during operation.
For this purpose use a soft wire with appropriate diam
-
eter.
NOTE:
The condition of the oil passages can be easily
checked. If the passages are clear, the chain will auto
-
matically give off a spray of oil within seconds of starting
the chain saw. Your chain saw is equipped with an auto-
matic oiler system.
CHAIN MAINTENANCE
WARNING:
Unless you have experience and special
-
ized training for dealing with kickback, always use a
low-kickback saw chain, which significantly reduces the
danger of kickback. Low-kickback saw chains do not
completely eliminate kickback. Low-kickback or “safety”
chains, should never be regarded as total protection
against injury.
Always replace a worn out chain with a new low-kick-
back chain.
SHARPENING THE CHAIN
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 in the
nearest SPARKY service centre. If you feel comfortable
sharpening your own saw chain, special tools are avail
-
able from hardware stores.
Never saw with a blunt chain. A chain is considered blunt
when you have to push the chain saw into wood and the
chips are very fine (sawdust).
The height difference between the tooth A and the ridge
B is the cutting depth. When sharpening the chain you
have to consider the next points:
(Fig. 18a, 18b)
- Filing angle;
- Cutting angle;
- File position;
- Round file diameter;
- Filing depth.
For correct sharpening of the chain you need good tools;
for example a round file and mould. Consult a profes
-
sional at the hardware store.
WARNING:
The risk of kickback increases if:
- sharpening angle is too large;
- cutting angle is too small;
- round file diameter is too small.
Check if the chain is properly tensioned prior to start
sharpening.
Engage the chain brake to lock the chain on the bar.
Use a round file with diameter 1,1 times the cutting tooth
depth.
Always file from the inside of the tooth to the outside.
First file all teeth on one side, then turn round the chain
saw and file the teeth on the other side.
File at angle perpendicular to the bar and at 38o to the
travelling direction.
After sharpening, the cutting links must all have the same
width and length.
When the length of the teeth is only 4mm, the chain is
worn and should be replaced.
(Fig. 18c)
STORAGE
▪ Empty the oil tank after you have completed work!
▪
When storing the machine in its original packaging the
oil tank must be completely emptied.
▪ To prevent leakage lay the machine down horizontally
(with the oil tank cap facing upwards).
▪
Clean the machine with a soft brush or dry cloth with-
out using solvent.
▪ Store in a secure, dry place out of the reach of chil
-
dren.
▪ When storing the machine for long periods remove
the guide bar and the chain and store them well lu-
bricated.
GENERAL INSPECTION
Regularly inspect all fasteners and ensure they are
properly tightened. Should any of the screws be loose,
retighten it immediately to avoid hazards.
If the replacement of the supply cord is necessary, this
has to be done by the manufacturer or his agent in order
to avoid a safety hazard.
