Rotating Four-Point Teeth
1. When the original side gets worn down or chipped,
the tooth can be turned either 90 or 180 degrees
to expose fresh cutting surfaces on the tooth.
Alternately, the four-point teeth can be lightly
sharpened using a flat disc grinder to bring an
edge back. Keep in mind that you are removing
the hard surface from the face of the tooth, so do
not grind too much.
IMPORTANT:
Do not weld on the teeth. Modified
teeth may break during operation.
2. After rotating the tooth, re-torque the locking bolt
to 350 ft.-lbs. If bolts are damaged, replace them.
NOTE:
If you reposition or replace worn teeth on
the disc, be sure to do the same to the tooth on
the opposite side of the disc to maintain disc
balance.
Bullet Teeth Replacement
The bullet teeth can be installed and removed by
using the supplied tool (located under the rear cover).
Slide the tool into the slot in the tooth as shown at
right, and hit the tool with a hammer to either install or
remove the tooth. Never hit the tooth directly with the
hammer
– doing so will damage the tooth.
Cleaning the
Attachment
1. Position the attachment flat on the ground.
To avoid injury or death, never
service the attachment in the raised position.
Always service with the attachment sitting flat
on the ground or supported by an approved
lifting device or blocks.
2. Remove the top shields to access the motor
cavities.
3. Use low pressure water or a small brush to
remove any unwanted dirt and debris.
Use care when removing any
debris wrapped around the teeth or disc. Disc
can rotate suddenly.
4. Reinstall shields when complete.
