Maintenance; Chain Sharpening - Ozito OZPCS305A Operation Manual

MAINTENANCE

Note: Before cleaning your chainsaw or carrying out any maintenance procedure,
make sure that the engine is off and is cool. Disconnect the spark plug to prevent
accidental starting.
Maintenance to be preformed after each use
1. Loosen the filter cover knob (7) and remove
the filter cover (8).
2. Remove the air filter (as shown to the right).
3. Split the air filter into its two halves and clean
the mesh. Dry particles can be removed by
tapping on a hard surface. More stubborn dirt
may require washing out the filter with petrol
or using an air compressor.
4. Re-assemble the two halves and replace the airfilter,
filter cover (8) and filler cover knob (7).
5. Take off the guide bar (14) and maintain it as follows,
remove any saw dust from the groove in the
guide bar (14).
6. Make sure that the oil port is not clogged. Grease
the nose sprocket at the tip of the guide bar (14).
7. Check for fuel and oil leakage and loose fastenings,
especially those securing the handles and the
guide bar (14).
8. Clean any dust away from the cooling vents as
clogged vents can cause overheating.

Chain sharpening

Sharpen the chain regularly to maintain optimum
performance of the saw. Signs of a dull chain are:
• The sawdust becomes powder-like
• Extra force is required to execute a cut
• The cut does not track in a straight line
• Increased vibration
• Increased fuel consumption
Warning! Wear heavy gloves when handling the chain. Hold the guide bar
(14) securely in a vice.
Sharpen each cutter using a chain file. Always use outward strokes. After
sharpening, the cutters must all have the same width and length.
After every 3-4 times use an authourised repair centre to professionally sharpen
your saw chain. They have the special tools necessary to ensure the correct cutting
angles and depths.
