6.1.1 General
Before any maintenance operations:
•
Put the switch (18) in OFF position.
•
Disconnect the compressed air hose.
•
Put safety gloves on.
6.1.2 Chain tension adjustment
Perform the following operations:
•
Loosen the nut (14).
•
Turn the screw (33) clockwise to stretch the chain (11), anti-clockwise to loose it.
•
Fix the nut (14).
6.1.3 Replacing the chain
Perform the following operations:
•
Unscrew the nut (14) and the two screws (12) which fix the front protection (13).
•
Loosen the chain bar (10) by unscrewing the screw (33) anti-clockwise.
•
Remove the bar (10) with the chain (11) and replace it taking care of the correct position of the cutting teeth (see picture E).
•
Assemble the bar (10) with the new chain (11), then the protection (13), and screw the nut (14) partially.
•
Stretch the chain (10) by screwing the adjusting screw (33) clockwise.
•
The chain has to be adjusted so that it is well stretched and can be easily moved by hand.
•
When the right tension has been reached, fix the nut (14) and screw the two fixing screws (12) of the front protection (13).
6.1.4 Replacing the chain bar
•
Remove the two screws (12) locking the front protection (13).
•
Remove the nut (14) and the front protection (13).
•
Loosen the chain bar (10) unscrewing the screw (33) anti-clockwise.
•
Disassemble the bar (10) and the chain (11) and replace it.
•
Insert the bar into the chain tensioning pin, then insert the washers into the bar pin and screw the nut (14) without locking it.
•
Assemble the chain onto the bar drive and the sprocket. Take care of the chain rotation direction and of the correct cutting
teeth assembly and position.
•
Stretch the chain bar (10) screwing the adjusting screw (33) clockwise.
•
The chain has to be adjusted so that it is well stretched and can be easily moved by hand.
•
When the right tension has been reached, lock the nut (14) and screw the two fixing screws (12) of the front protection.
6.1.5 Lubricating the chain bar
The oil flow on the chain has been pre-set by the manufacturer. It is automatic and does not need any adjustments.
Always check the oil level in the reservoir (26). The lubrication is carried out automatically.
Use SAE 30 oil to lubricate the chain (11). To add oil, unscrew the tap (23) in the upper part of the chainsaw body.
WARNING!
The lack of lubrication may cause seizing of the chain (11) of the bar (10).
6.1.6 Maintenance at the end of the work
At the end of the work, before storing the tool for a period of time, it is suggested to put some oil drops into the air coupling (15)
in the handle (17) and to make the chainsaw idle for some seconds. This will avoid the formation of deposits due to air moisture.
WARNING!
Remove the front protection (13) periodically and eliminate the cutting residues, which might prevent the inertial chain
brake (28) from working perfectly.
