Chain oil
NOTE: Preferably use biodegradable chain oil to minimise the environmental impact.
1. Place the chain saw on a stable surface with the filler cap facing up.
2. Clean the cap and the area around it, if necessary.
3. Open the filler cap slowly and take it off.
4. Carefully fill with chain oil. Avoid spilling.
5. Check the oil level in the sight glass. The oil level should be between the MAX and MIN markings.
6. Tighten the filler cap by hand.
7. Wipe up any spilled oil.
Sharpening the chain (Img. 16)
A worn or incorrectly filed chain can cause kickback, which can result in fatal and/or serious personal injury.
Wear heavy-duty safety gloves when handling the guide bar and chain.
• The filing should be done with a special tool to ensure that the chain has the right angles and height.
• All the drive links should have the same height. Different heights of the drive links will cause the chain to run out of balance and damage it.
• The minimum size of drive links is 4 mm. Discard the chain if they are less. The angles of the cutting edges must be maintained. File with 2 or 3 strokes from
inside and out.
• File the chain with a round file. Always file the cutting edges from inside and out. Pay attention to the values given in the diagrams. After filing all the drive
links should have the same width and height.
• The height of the rakers should be checked after 3 – 4 filings. If necessary, file down the rakers with a file template and flat file, and round off the front edge.
Guide bar
• Turn the guide bar round every 8 working hours to ensure that it wears uniformly.
• Use a cleaning tool to keep the slot and lubrication holes clean.
• Check the guide bar at regular intervals for wear and damage, and replace if necessary.
• Clean the oil channels on the guide bar to ensure proper lubrication of the guide bar and chain.
Never fit a new chain on a worn sprocket or worn guide ring.
Chain tension
A new chain must be tensioned after no more than 5 cuts. Once the chain has been run in it does not need to be tensioned as often.
The chain is correctly tensioned when it rests against the underside of the guide bar, but can still be easily pulled along by hand.
Adjust the tension of the chain when necessary:
1. Unscrew the nuts about 1 turn.
2. Lift the tip of the guide bar a little.
3. Tension the chain with the screw until the chain is flush with the underside of the guide bar.
4. Tighten the nut.
Do not tension the chain too tightly, this will result in abnormal wear and reduce the life span of the chain and of the guide bar.
STORAGE AND TRANSPORT
Long-term storage
• Store the chain saw out of reach of unauthorised persons.
• Allow the chain saw to cool before putting away.
• Store the chain saw horizontally.
• Remove the chain if the saw is not going to be used for a long time.
• Store the chain saw in a dry place.
Transport
Follow the instructions below when transporting in a vehicle:
• Make sure the guard is fitted over the guide bar.
• Secure the chain saw so that it cannot move.
• If possible, transport the chain saw in its original packaging.
