Operation

NOTE: 

Under  operating  conditions,  rated  case

drain pressure must not be exceeded.

NOTE: 

During cold  start, case pressure must  be

kept below maximum case pressure.

NOTE: 

Operation with case pressure in excess of

stated  limits  will  damage  seals,  gaskets,
and or hydraulic motor housings.

See page 49 in Maintenance Section for causes of
high case drain pressure.

Starting the Drum Mulcher

 

IMPORTANT

At the sign of any unusual vibrations during
operation,  stop  and  inspect  for  loose,
damaged or missing cutting teeth.

CAUTION

The  cutting  drum  must  not  exceed  2400
rpm. Serious damage can result.

Install the drum mulcher onto the machine.

Move  to  the  operator’s  position,  lower  seat  bar,
start the engine and release the parking brake.

Raise the drum mulcher slightly off the ground to
allow the mulcher drum to rotate freely.

With  the  machine’s  engine  RPM  just  above  idle,
engage  the  auxiliary  hydraulic  flow  (see  the
machine’s  operator’s  manual)  to  the  drum
mulcher.  Allow  the  hydraulic  system  to  properly
warm up.

Slowly  raise  the  machine’s  engine  RPM  to  the
correct maximum speed and begin mulching.
