DANGER! When carrying out maintenance work on or near the blades be careful of free-swinging
blades over-centering and falling. Ensure 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.
When servicing or inspecting blades of any type when the machine wings is raised, it is important to ensure
that the blade carrier and blade assembly is moved into its “dropped” position to ensure nothing suddenly
falls due to the force of gravity. When the Multicut machine is raised this should automatically happen, but any it
hasn’t, hold the blades towards the outside and gradually rotate and pre-place them into their dropped position;
as shown in Figure 5.19. This will ensure that personnel do not get hit by falling blades or pinched/trapped
between the blade and the carrier.
Figure 5.19 – Beware Of Falling Blades
Carefully wiggle the blade carrier assemblies and check each of the rotors for looseness of fasteners. Retighten
any loose parts to the correct torque figure. See Section 5.7 for torque settings. Blade carrier fasteners should
be checked after the first hour and then every 8 hours thereafter.
IMPORTANT: Operating with loose blade components will damage the blade carrier and blades. Whenever the
blades have been removed or replaced, the tightness of components should be checked after the first hour and
then every 8 hours thereafter.
When proceeding to inspect the blades, if any are showing any signs of severe wear, damage or cracking, they
must be replaced immediately. Never attempt to weld the blades, as this will make them very brittle and
dangerous. Do not take risks with cutting blades – if in doubt replace.
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 or blade carrier 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 and to reduce blade wear and potential detrimental damage, 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.
IMPORTANT: Always use genuine Spearhead parts when carrying out repairs and maintenance with thoughts
to longevity and reliability of the machine and personnel safety. Spearhead blades are made of special heat-
