Changing Engine Oil - B.W. Machinery GBK130 User Manual

 Put a block of wood into the hole (see Fig.18). Pull the starter cord some more
until the rotor is blocked. Now it is safe to unscrew blade bolts (see Fig.18).
Always use gloves when handling the blades.
 Remove the blade anvil (see Fig.19).
 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 threadlocker 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 0.95mm. (See Fig.20)
