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
