Blade/Anvil Replacement
Warning
Death, serious injury, and/or property damage can
result from improper maintenance of the unit. Do
not perform maintenance procedures on this unit
without proper training.
Only properly trained, authorized personnel which have
read and understand the entire manual, placards and
decals shall access the cutter head or perform blade
maintenance.
Accessing the Cutter Head
1. Reduce engine speed to low idle.
2. Turn engine off. Remove keys from the chippers
ignition. Place these keys in your pocket.
3. Remove negative battery cable.
4. Properly lock-out chipper (refer to LOTO procedure).
5. Inspect cutter and drive train to ensure no movement
of drive components.
Warning
Death, serious injury, or property damage can result
when attempting to access moving components.
Make sure components have come to a complete
stop before performing inspection or maintenance.
Drum and drive system components continue to move
after the clutch has been disengaged and the engine has
been turned off. Make sure the drive system has come
to a complete stop prior to accessing this area.
Caution
Injury can result from being pinched or trapped be-
tween moving components. Keep hands clear.
Never place any part of the body in a potential pinch
point. This not only applies to the head and feed roller,
but also drum and engine sheave/belt contacts.
Warning
Serious injury can result while performing blade
maintenance. Wear appropriate safety equipment.
Blades are extremely sharp. Care must be taken to avoid
contact with the blades and blade pinch points. Always
wear appropriate hand protection when performing in-
spections or replacing blades. Failure to do so will result
in severe injury.
The recommend service interval for blade maintenance is
eight hours or daily. However, the actual service interval
may be more or less, depending upon the wood being
chipped and the chipping conditions. Always complete
a thorough inspection if foreign objects are fed through
the chipper.
Notice
Always replace blades as sets. Drum balance can
be affected if matched blades are not kept together.
Blade Installation and Adjustment
Warning
Death, serious injury, or property damage can result
from operating the chipper with damaged or chipped
blades. Replace damaged or chipped blades to
prevent breaking and discharging of blades during
operation.
Always use Altec supplied chipper blades. These blades
are manufactured using special chipper blade steel and
selectively hardened to reduce the possibility of blades
shattering.
