Adjustments & Maintenance
ATTENTION
Review all safety information outlined in
safety section of manual before proceeding
with any adjustments or maintenance.
Lubrication
The FHX Series has 3 lubrication points,
identifiable by the presence of a grease fitting.
Use only BrushHound approved grease or a
compatible grease with similar specifications and
EP additives. For all 3 of the FHX
’
s grease points
BrushHound recommends using Mobilith SHC
100 Grease. Over
-
greasing seals and bearings
can cause damage, if grease purges from the
bearings
’
seals too much grease has been
applied. If the purged grease is black and smells
burnt, this may be a sign of chronic over
-
greasing.
a)Cutter Drum Bearings
On each end of the cutter drum, behind the bolt
on covers are the cutter drum bearings. These
are double row spherical bearings with high
speed Teflon seals, each comes with a grease
fitting and prepacked with high quality grease
from the factory. Greasing intervals are
dependent on conditions, but for standard use
the main bearings require 10 pumps of grease
from a manual grease gun every 60
-
80 hours of
operation. Abnormally wet conditions, where
bearings are continuously moist, may require
more greasing.
b) Overhung Load Adapter
In the motor compartment, mounting the motor
to the side wall is the overhung load adapter. It
has a grease line that runs to the top of the FHX
and comes prepacked with high quality grease
from the factory as well. The grease interval for
the overhung load adapter is 10 pumps every
300 hours, or every fourth cutter drum bearing
greasing.
Wearable Component
Maintenance
a) Rubber Drive Belt
The drive belt is located behind the pulley
housing cover on the drive side of the
attachment. The belt itself has a lifetime of
over 1000 hours, but should be inspected
regularly for excessive wear. If the belt
appears worn thin or torn it should be
replaced. It should also be replaced
whenever the cutter drum is removed.
•
Drive Belt Tension
-
Drive belt tension
can be achieved by first removing the
drive side pulley cover and the motor
guard cover. With the covers removed
you will gain access to the overhung load
adapter mounting plate. The over hung
load adapter mounting plate has bolts
that when tightened pull the entire
assembly toward the mounting plate,
putting tension on the drive belt.
b) Hydraulic Hoses
The hydraulic hoses located within the motor
guards have been placed to minimize their wear
caused by rubbing against metal surfaces.
However, due to heavy vibration their positions
can shift so regular inspection for excessive wear
should be performed.
c) Bearings
Bearing failure can be indicated by excessive
vibration or noise or the complete seizing of the
cutter drum altogether. Imminent bearing failure
signs can be more subtle and go unnoticed
without appropriate diagnostic equipment. As a
precaution, bearings should be replaced every
1500
-
2000 hours of operation depending on the
environment and usage conditions.
d) Safety Guards
Safety guards are in place for the protection of
the Operator, bystanders and nearby property
and should never be removed for operation.
Therefore, it is important that each safety guard
