SERVICE INSTRUCTIONS
CHANGE BLADES
WARNING
Wear riggers gloves for the blade changing operation.
WARNING
Always sharpen blades on a regular basis. Failure to do so
will cause the machine to under perform and will overload
engine and bearings causing machine breakdown. Blades
must not be sharpened beyond the wear mark (see diagram).
Failure to comply with this could result in machine damage,
injury or loss of life.
1. Turn off the chipper and remove the key.
2. Remove the negative battery lead.
3. Turn the discharge tube to point across the
machine.
4. Use a 24mm socket with extension bar to
remove the two M16 nuts clamping the rotor
housing shut.
5. Carefully lift the rotor housing until its rests on
its stop.
6. Using the fan blades turn the rotor to blade
change position as shown and insert the
locking bar through the rotor housing and rotor.
7. Brush away all dirt and debris from the rotor
and blades.
8. With a 24mm spanner/socket undo the two
nyloc nuts that are holding the blade in place.
9. Grasp the blade by the flat edges while
wearing heavy duty gloves.
10. Withdraw the blade from the rotor.
11. If the blades are being rotated and not
replaced, do not remove the blade bolts.
12. If the blades are to be renewed, place the
blade on a flat surface and tap the top of
the blade bolts with a hammer. The bolts
are designed for this. They should loosen
from the blade. Withdraw them completely.
13. Clean the back surface of the blade, blade
bolts and blade area of the rotor before
reseating blades. The blades must not
have any material underneath them
when tightened. If they are not flat and
tight they will become loose quickly.
14. Reassemble the blades, bolts, washers and
nuts in the order shown in the diagram
above. Use only genuine Timberwolf nuts
and washers, as they are of a higher grade
than normally stocked at fastener factories.
Failure to use the appropriate grade nuts or
washers may result in damage, injury or
death. The use of genuine Timberwolf
blades and bolts is recommended.
15. Apply a smear of anti seize compound
(copper ease) to the bolt threads and back
face of the nuts. Do not apply copper grease
onto the counter bore faces of the blades or
bolts.
16. A calibrated torque wrench must be used
to tighten the bolts to a torque setting of
125 lbs ft (170 Nm).
18. Remove the locking bar, rotate rotor to the
next blade then repeat steps 8-16.
19. Slowly lower the rotor housing to its original
position.
20. Refit the two M16 nuts and tighten to
60 lbs ft (80Nm).
21. Re-attach battery lead.
THIS PROCEDURE SHOULD ONLY BE UNDERTAKEN WITH THE DISCHARGE IN PLACE.
