MAINTENANCE
Proper maintenance of the attachment will
result in longer life and the more produc-
tive and cost effective operation. There are
two basic categories of maintenance re-
quired, pick/holder replacement and
component lubrication. For proper opera-
tion, the picks should be checked each four
(4) hours and lubricated daily with a water
based emulsifying agent to ensure that they
can freely rotate in their holders.
BEFORE PERFORMING ANY MAIN-
TENANCE ON THE UNIT, PERFORM
THE MANDATORY SAFETY SHUT-
DOWN PROCEDURE.
WARNING
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 in-
cluded 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 ac-
cess to the bottom of the holders can be
used.
IMPORTANT
Welder must be grounded directly to drum
during pick holder replacement or
SEVERE
BEARING DAMAGE WILL RESULT.
A length of pipe with a 3/4 to 1 inch inside
diameter can be placed over the pick to pro-
tect it from a direct hit. Striking a small piece
of wood placed on the pick to absorb the
shock will prevent damage.
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, RESULTING IN
PREMATURE WEAR.
WARNING
ALWAYS WEAR SAFETY GLASSES
WHEN PERFORMING THIS OPERA-
TION. HARDENED TOOLS AND PICKS
CAN SHATTER CAUSING INJURY.
WARNING
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 lubricant 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.
NOTE: always disconnect the ECU, radio
receiver and master panel prior to any
welding.
