knife bolts.
Knives:
ATTENTION! When carrying out any kind of service on or around the rotors
always pay attention to the swinging knives. Always wear safety gear, including
helmet, work gloves and safety glasses.
It is possible to sharpen the knives by sharpening the cutting edges, ensuring that the
knives after sharpening are the same lenght and weight. Be careful not to let the
knives get too hot during sharpening as this will affect the temper. All knives are
swinging freely and rotate around hardened steel bushes that are replaceable. When
changing the knives 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 knives.
If the knives show signs of severe wear, damages or cracks they must be
replaced immediately. Never attempt to weld the knives as this will leave
them brittled and extremely dangerous. Never take a risk with the
knives
– if in doubt, replace them.
When the sap disappears from the branches the end result will become more ”frayed”.
When operating off growth season the knives will wear out faster. The best result is
gained between April and October.
