BLADES:
ATTENTION! When carrying out any kind of service on or around the rotors
always pay attention to the swinging blades. Always wear safety gear, including
helmet, work gloves and safety glasses.
It is possible to sharpen the blades by sharpening the cutting edges, ensuring that the
blades after sharpening are the same length and weight. Be careful not to let the
blades get too hot during sharpening as this will affect the temper. All blades are
required to swing freely and rotate around hardened steel bushes that are replaceable.
When changing the blades it is important to always change them by the pair to
maintain the balance of the rotor. Bushes must always be changed when mounting
new blades.
If the blades show signs of severe wear, damage or cracks then
they must be replaced immediately. Never attempt to weld the
blades as this will leave them brittle and extremely dangerous.
Never take a risk with the blades
– if in doubt, replace them.
When the sap disappears from th
e branches the end result will become more “frayed”.
When operating off growth season the blades will wear out faster. The best result is
gained between April and October.
