SAFETY SHUTDOWN PROCEDURE.
MAINTENANCE
Proper maintenance of the attachment
will result in longer life and the more
productive and cost effective operation.
There are two basic categories of
maintenance required, pick/holder
replacement and component lubrication.
For proper operation, the picks should be
checked each four (4) hours and lubri-
cated daily to ensure that they can freely
rotate in their holders.
Pick/Holder Replacement
As regular use takes place, normal wear
of the carbide picks will occur with the
outer most picks wearing first. The pick
tool included with the cold planer
should
be use to remove the picks from the cast
holders. In the event the pick tool is not
available, any hardened punch or tool
allowing access to the bottom of the
NEVER DRIVE THE PICK BY STRIK-
ING DIRECTLY ON THE END OF THE
PICK AS THIS CAN CAUSE THE PICK
TO CHIP AND CAUSE INJURY OR
CREATE SMALL STRESS FRAC-
TURES IN THE PICK RESULT-
ING IN PREMATURE WEAR.
A length of pipe with a 25mm inside di-
ameter can be placed over the pick to
protect it from a direct hit. Striking a
small piece of wood placed on the pick to
absorb the shock will prevent damage.
The factory installed carbide pick chosen
for use is a general purpose pick as the
cold planer is designed for both asphalt
and concrete applications. Picks de-
signed for extended periods of concrete
cutting are available from the factory or
your dealer.
To prevent the picks from seizing in the
holders, the picks should be sprayed
with a lubricate at the end of each day.
This will break down the asphalt build up
in the holders and prevent premature
wear by allowing the picks to rotate in
the holders. Excess lubricant should be
caught in a collection pan and properly
disposed of.
If the pick remains in the holder beyond
its intended replacement point, it reduces
the cutting performance and will not pro-
tect the holder. Inspect the cutting drum
every hour of operation. Check the picks
and holders for wear. If the picks are
worn enough to indicate slight holder
wear, replace the picks.

ALWAYS WEAR SAFETY GLASSES
WHEN PERFORMING THIS OPERA-

CAN SHATTER CAUSING INJURY.
IMPORTANT
Welder must be grounded directly to
drum during pick holder replacement or
SEVERE BEARING DAMAGE WILL
RESULT.
