Original instructions (ENGLISH)

If any of these visual damages are found, replace
all blade bolts, nuts and bushes
on that rotor
immediately
.
IMPORTANT:
Always replace blade bolts, nuts and bushes with new components
whenever the machine
blades are removed and/or replaced.
WARNING!
Inspect the area before mowing. Foreign objects should be removed from the site prior to
beginning work to prevent machine damage and/or operator, bystander or the environment. Any objects
that cannot be removed must be clearly marked and carefully avoided by the operator.
WARNING!
Pay special attention when working with the machine and do not allow the machine to touch
fixed objects such as road drains, walls, shafts, curbs, guard rails, tracks etc. as these could break the
blades which could cause debris to be thrown at very high speed from the machine. As a precaution
raise the cutting height of the machine to 150mm (6 inches) to ensure they do not collide when the
machine is in work.
As a preventative measure inspect the destined working area of the machine to determine where foreign object
hazards are. Remove these hazards and if they aren’t easily removable, place visual markers where items are to
ensure that the tractor and machine does not come into contact with these hazards.
5.4.6
Anti-scalp Dish Inspection (if fitted)
On the standard blade carrier an anti-scalp dish is found on the bottom of each of the rotors of the machine to
protect the blades and the driveline. However, like the blades are potentially prone to coming into contact with
immovable objects while the machine is in work.
Inspect the machine anti-scalp dishes before each use to
determine that they are properly installed
, secure and in good condition.
Replace any blade carriers which
are excessively nicked, worn or have any other damage
.
See Figure 5.23 for some visual indications of worn anti-scalp dish lower blade carriers.

DANGER!
When carrying out maintenance work on or near the blade carrier be careful of free-swinging
blades over-centering and falling. It is recommended that Personal Protection Equipment (PPE) is worn.
WARNING!
Avoid personal injury.
Never work
under the machine without fixed support stands to
ensure that the deck does not fall.
