WARNING! Always use protective gloves when handling the chain.
WARNING! Before carrying out any work on the tool, switch off the
internal combustion engine.
BAR AND CHAIN
1 Assembly of the bar, the chain, and the housing (Fig. A)
- Put the chain (12) in lubricating oil and leave there for some hours.
- Check that the emergency brake is released by pulling the hand
guard (no. 8) toward the front handle.
- Place the chain saw on a flat surface and remove the nut/s ( 17) and
the housing (18). Also remove the plastic spacer (29), if present,
inserted in the fixing pin. This spacer (Fig.F) must not be used!
- Using a screwdriver, turn the chain adjustment screw counter-
clockwise (15) until the end of the screw.
- Slip the bar groove (21) over the fixing pin/s (16) and pass the chain
over the sprocket (19). During this phase it is important to centre
the tensioning pin (20) on the lower hole of the bar (22).
- Insert the chain in the bar grooves making sure to respect the correct
direction of the chain (Fig. E).
- Assemble the housing (18) and, holding the nose of the bar upwards
(using gloves!), fix the nut/s (17) tightly.
WARNING! Do not use the chain saw before tensioning the chain.
2 Tensioning the chain (Fig. A)
- Loosen the bar fixing nut half a turn (17).
- Using a screwdriver, turn the chain adjustment screw clockwise
(15) until the chain has reached the correct tension.
N.B.: Checking the correct tension. The correct tension is reached
when you are able to manually lift the chain 3-4 mm to the centre
of the bar (Fig.C).
- If the chain is too tense, loosen the nut/s (17) and the chain
adjustment screw (15) and push the bar leftwards in such a way
as to make it slip into place.
- Repeat the adjustment taking care to tighten the screws less (15).
- When the chain has been adjusted, fix the nut/s (17) securely, always
holding the nose of the bar upwards.
- Check for the correct tension again.
- Lubricate the chain and bar rail with specific oil.
WARNING! During the first cuts, when the machine is still new,
the chain will loosen quite frequently, but this is normal during the
breaking-in period of a new tool.
WARNING! Never leave the chain loose as it may come off the
bar while cutting.
WARNING! If the chain is too tight, it could cause overheating and
damages. It is forbidden to use the machine without lubricating
oil for the chain.
OPENING THE GUARD
Follow the instructions below to remove the guard correctly (no. 18):
1 – Pull the hand guard no. 8 towards the hand grip
2 - Remove the bar fixing nuts no. 17.
3 – Loosen (unscrew) the chain tensioning screw no. 15
4 – Extract the guard.
