9.2.4
Flail Replacement
The rotor and flails should be inspected for wear or damage on a regular basis
– missing, damaged or worn flails
should be replaced immediately. When replacing a flail, the diametrically opposite flail should also be replaced
at the same time in order to maintain rotor balance. All replacement flails should be fitted with new retaining
bolts and locknuts.
DANGER!
: Machine and tractor should be switched off and the starting key removed at all times when
inspecting or maintaining the machine
– Never work on a machine that is switched on and
running.

Filter(s)
The element(s) must be changed after the first 50 hours work and thereafter every 500 hours.
9.3.3
Hoses
It is false economy to try and make a damaged hose last a bit longer, because a failure can spill a lot of oil on the
road endangering traffic, the environment and costing money. To reduce the risk of this happening and ensure a
long life from the hoses, follow the guidelines below. On a weekly basis:
Check that all hoses and their connections are in good condition and that there are no leaks or
damage. Replace any hose that is leaking or damaged.
Check to see that hoses are not and have not been chafing against sharp edges. If evidence of
chafing is found, then inspect for damage and if found replace. Re-route any hose that has been
chafing; see section on ‘Hydraulic hose checks’ in ‘Installation’ chapter.
Check to ensure that hoses are fitted without kinks or sharp bends.
If in doubt about the condition of any hose replace it. When replacing hoses, be sure to tighten to the
correct torque setting, see Figure 9.3.
WARNING!
Some hoses may contain residual pressure, take care when removing them.
