Schematics

General

This  section  contains  schematics  to  be  used  for  locating  and  correcting  most  of  the  operating
problems  which  may  develop.  If  a  problem  should  develop  which  is  not  corrected  by  listed
corrective  actions,  technically  qualified  guidance  should  be  obtained  before  proceeding  with
any maintenance.

Troubleshooting

It  should  be  noted  that  there  is  no  substitute  for  a  thorough  knowledge  of  the  equipment  and
related systems.

It  should  be  recognized  that  the  majority  of  the  problems  arising  in  the  machine  will  be
centered in the hydraulic and electrical systems.

The  first  rule  of  troubleshooting  any  circuit  that  is  hydraulically  operated  and  electrically
controlled  is  to  determine  if  the  circuit  is  lacking  hydraulic  oil  and  electrical  control  power.
This can be ascertained by overriding the bypass valve (mechanically or electrically) so that oil
is  available  to  the  function  valve,  then  overriding  the  function  valve  mechanically.  If  the
function performs satisfactorily, the problem exists with the control circuit.

Hydraulic Circuit Checks

The  best  place  to  begin  the  problem  analysis  is  at  the  power  source  (pump).  Once  it  is
determined  that  the  pump  is  serviceable,  then  a  systematic  check  of  the  circuit  components,
beginning  with  the  control,  would  follow.  For  aid  in  troubleshooting,  refer  to  the

followed

hydraulic schematics and Electric schematics.
