maintenance by maintaining the proper oil
level in the hydraulic reservoir and
replacing the oil filter when required by the
equipment manufacturer. Maintenance
and inspections should be performed as
follows.
Daily Inspection:
The following items should be checked
daily.
1. With the clutch disengaged and the
ENGINE OFF in a cooled condition, the
oil level indicator on the oil reservoir
should be visually checked to insure
that the oil level is at the proper level. If
needed, add additional oil to the
reservoir.
500 hours of operation:
The following items should be checked
after the
first 500 hours of operation and
every 500 hours after that:
1. Check all HPTO bolted connections
and hydraulic connections.
2. Change the equipment system oil and
filter per equipment manufacturer’s
recommendations.
5000 hours of operation:
The HPTO unit must be serviced and
inspected after 5000 hours of operation. If
the HPTO unit is allowed to operate
beyond this point, the torque may drop
rapidly and possible damage to the unit
