ROUTINE MAINTENANCE
Pick Inspection, Setup, Removal, & Installation
Inspection:
The factory installed carbide picks are specifically
designed to be a wear product. The life expectancy
of the picks will depend greatly on the hardness, the
abrasiveness, and the thickness of the material
being cut. It is also very critical that the picks rotate
freely in the holders to maintain even and consistent
wear throughout the life of the picks. A normal pick
wear progression is depicted to the right. The pick
seen furthest to the right is an example of one that
should be replaced, with the carbide almost gone
and the body is nearly worn to the base.
IMPORTANT:
Continued use of the picks beyond
this point will have adverse effects, such as poor
productivity, possible cutter head failure, and other
costly repairs.
NOTE:
Examples of abnormal pick wear causes and
solutions are on page 23.
NOTE:
See the parts explosion on page 17 for
replacement pick packages and part numbers.
Cold Planer Tooth Replacement
Always wear safety glasses
when performing this operation. Hardened
tools can shatter
causing injury.
1. Open the front cover to allow free access to the
cold planer drum.
2. Make sure the cold planer cutter head is
positioned in such a way that the drum is allowed
to rotate freely.
3. The tooth removal tool included with the planer
should be used to remove the teeth from their
holders.
4. To remove a tooth, place the fork end of the tool
into the grove in the tooth and strike raised area
on the tool with a hammer until the tooth is
removed.
5. To install a new tooth, place the fork end of the
tool into the grove in the tooth and set the shank
end of the tooth over the hole in the tooth holder.
6. Then strike the raised area on the tool with a
hammer until the tooth is fully seated into the
tooth holder.
