5.2 Chipper Parts Regularly Checking
Check all the parts regularly (1-2 times a month) including bearing, blades, belt and
etc. Make sure the blades are sharp. Replace the blades as soon as the chipping
performance begins to deteriorate. Blunt blades will impact working efficiency and
cause damage to the machine.
5.3 Changing the blades:
❖ Stop the engine (Put the on/off switch in the "off" position) and disconnect the
safety switch cable.
❖ Remove the feeding chute. (Two people required)
❖ Put a block of wood into the hole (see Fig.1). Pull the starter cord some more
until the rotor is blocked. Now it is safe to unscrew blade bolts. Always use
gloves when handling the blades.
❖ Remove the blade anvil (see Fig.2).
❖ Give a really good clean of chipper blades and anvil and make sure there is no
dirt.
❖ Put anvil back to the chipper and screw on (make sure to keep anvil bolts loose as
you need to adjust it later).
❖ Use thread locker on blade bolts (make sure you don't use too much, normally
just a small dip) and screw on the blades (make sure all bolts are tightened).
❖ After installing the blades, check the gap between the blades and the anvil. The
gap should be no smaller than 0.5mm and not bigger than 1mm. (See Fig.3)
