40 Nm
.
5.1.1.2 After 10 hours work all bolts, screws and retightened
5.1.1.3 All bolts shall be retightened / checked every 8 hour.
5.1.1.4 The plastic rail needs to be adjusted down to the blades, with a distance of 1 mm. If there is more than 5 mm,
replace it. Branch deflectors need to be adjusted as close as possible to the saw blades, without touching the
blades.
5.1.1.5 Remove the protection cover to the belts, and clean the inner housing for dirt.
5.1.1.6 Inspect, and if necessary adjust the belts. See Figure 5.1

WARNING!
Replace the hydraulic hoses each time they are damaged or, in any case, before the sixth
year. The used hydraulic oil must be properly collected and must not be dispersed into the
environment since, according to the laws in force, it is classified as dangerous waste and for this
reason it must be given to the proper collecting centres. Please, refer directly to the closest company
for the collection of the used oils.
