4.1 MAINTENANCE-GENERAL
Proper maintenance of the attachment will result
in longer life and more productive and cost effec-
tive operation.
Maintenance can be divided into four basic cate-
gories
.
1. Pick/holder replacement
2. Milling Head lubrication
3. Belt maintenance
4. Engine Maintenance
Prior to operating the attachment, read this entire
manual.
Follow all safety guidelines in this manual and
safety decals on the unit.
Always follow the
MANDATORY SAFETY SHUT-
DOWN PROCEDURE
before performing ANY
maintenance.
Make sure that all guards, shields, and decals are
in place and in good condition prior to operation
.
FAILURE TO FOLLOW THE
PROCEDURES BEFORE CLEANING,
ADJUSTING, LUBRICATING, OR
SERVICING THIS UNIT COULD LEAD
TO SERIOUS INJURY OR DEATH.
WARNING
4.2 CUTTING DRUM MAINTENANCE
Cutting Drum maintenance is critical to ex-
tending the life of the pick and holder and
overall production of the RoadHog. Inspect
the cutting drum every 30 minutes of opera-
tion.
The factory installed carbide pick is a general pur-
pose pick and is designed for milling both asphalt
and concrete. Picks designed for extended peri-
ods of concrete cutting are available from the fac-
tory or your dealer.
Pick life varies with depth, density, material, ag-
gregate and maintenance, which includes allow-
ing the tooth to rotate. To maximize pick life, the
picks must be free to rotate in the holder. The
pick has two functions: serves as the consuma-
ble 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
Edge teeth will always wear faster than center
teeth, due to side loading of the drum during the
loader’s steering corrections.
To promote pick rotation, spray the picks daily
with a water based asphalt emulsifier to break
down asphalt emulsion.
( Example: Zep’s part # AR6690 )
As regular use takes place, normal wear of the
carbide picks will occur with the outer most picks
wearing first.
If the pick remains in the holder beyond its intend-
ed replacement point, it reduces the cutting per-
formance and will not protect the holder. Check
the picks and holders for wear. If the picks are
worn enough to indicate slight holder wear, re-
place the picks.
RoadHog recommends using a water spray kit.
Using water may increase tooth life by 20 to 40%
and also suppresses the milling dust.
