Proper maintenance of the attachment will result in
longer life and the most productive and cost effective
operation. There are two basic categories of mainte-
nance required, pick/holder replacement and compo-
nent lubrication. For proper operation, the picks should
be checked each four hours and lubricated daily to
ensure that they can freely rotate in their holders.
PICK 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 planer should be used
to remove the picks from the cast holder. In the event
the pick tool is not available, any hardened punch or
tool allowing access to the bottom of the holders can
be used.
A
WARNING
Never drive the pick in by striking it directly on
■
the end as this can cause the pick to chip and
cause injury or create small stress fractures in the
pick resulting in premature wear.
A length of pipe with a 3/4 -1 inch inside diameter 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.
A
WARNING
Always wear safety glasses when performing
■
this operation. Hardened tools and pick can shatter
causing injury.

MAINTENANCE
To prevent the picks from seizing in the hold-
■
ers, the picks should be sprayed with diesel fuel at
the end of each day. This will break down the
asphalt build-up in the holders and prevent prema-
ture wear by allowing the picks to rotate in the
holders. Excess diesel fuel should be caught in a
collection pan and properly disposed.
LUBRICATION
Lubricate the grease points daily on all planer wheels
as well as the drum bearings.
The lubricant in the gear case of the planetary must be
changed within the first 50 hours of operation. After
that, the lubricant need only be changed once per year
or every 1000 hours whichever occurs first.
Type of lubricant should be 80W-90 gear lube,
■
with an EP (extreme pressure) rating of GL-5 mini-
mum. Nineteen ounces is required for each
change.
The lubricant can be changed by removing the drain
plug located on the planetary gearbox flange between
the chassis and the drum. Rotate the drum until the
plug is at its lowest position and remove the plug (it
may be necessary to temporarily remove the drive
motor to allow the drum to rotate). Allow lubricant to
drain. Rotate drum until the drain hole is aligned with
the inspection hole in the side of the chassis. Refill
gear case with nineteen ounces EP-90 gear lubricant.
Reinstall drain plug. Reinstall drive motor if it was
removed.
