all hoses. All fittings should be tight
and free of hydraulic leaks. Hoses
must be free of crimps or cuts that
might result in leakage. Check your
attachment before operation to make
sure all hose routings are kink-free and
allow for maximum movement of all
depth and side shift functions required
during normal operation.
Drum Assembly
For proper operation, teeth must be
installed in every holder on the drum.
Welds on holder and blocks should
be inspected weekly for cracks. Any
cracks should be fixed as soon as pos-
sible. Teeth should be inspected daily
for wear. Tooth should be allowed to
freely rotate within their holders.
Holders should be inspected daily for
wear. Holder wear is not typically cov-
ered under warranty. Holders may be
hard-faced to replace worn holder ma-
terial.

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
MAINTENANCE ON THE UNIT, PER-
FORM THE MANDATORY SAFETY
SHUTDOWN 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 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 30 minutes 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.
See page 39 for these 3 locations.

19
Tooth is no longer rotating in the holder, causing premature tooth and holder wear.
Tooth maintenance ( and rotation ) is critical to extending the life of the tooth and tooth holder and overall production of
the RoadHog.
Check the condition of the teeth every 30 minutes, until wear patterns are determined under current conditions.
Tooth life varies with depth, density, material, aggregate and maintenance, which includes allowing the tooth to rotate.
Various tooth styles are available to match material and aggregate variables, which may increase tooth life and production.
Consult the factory for further assistance.
The tooth has two functions: serves as the consumable cutting tool and it protects the holder.
The tooth must be allowed to rotate in its’ holder. If it locks up, then tooth and holder wear is greatly accelerated
If the tooth is allowed to remain past its’ usable life, the holder will exhibit premature wear characteristics. ( see photo below ).
To promote rotation, spray the teeth daily with a water based asphalt emulsifier to break down asphalt emulsion.
Example: Zep’s Orange Response ( part number 0750 ).
Water should always be used, as it may increase tooth life by 20 to 40% and suppresses the milling dust.
Edge teeth will always wear faster than center teeth, due to side loading of the drum during the loader’s steering corrections.
Edge holders and drum edges are hard-faced at the factory and will be required throughout the machines life.
Tooth Maintenance
IMPORTANT

20
Warranty will not be allowed for failure due to the following: normal wear and tear, abuse or accident, excessive
flow or pressure, modification of original equipment, improper service or maintenance.
Roadhog does not warrant ANY ground engaging parts ( drums, teeth, holders or bases )
against wear, unless the wear is determined by Roadhog to have been caused by an engi-
neering or manufacturing defect.
Teeth may last twice as long if they are free to rotate in their holder
