6.0 Maintenance Instructions
This chapter contains all normal maintenance instructions to properly maintain your machine.
6.1 Engine
Refer to the manufacturer’s operating and maintenance instructions for the engine.
6.2 Hydraulic System
Check hydraulic fluid daily.
Change hydraulic filter every 250 hours of machine operation. Replace if necessary.
Change hydraulic fluid every 500 hours of operation.
6.3 Heat Transfer Oil
Check the oil level at the start of every day.
Change the oil every 500 hours of machine operation or 1 year, whichever comes first. Failure to
follow this oil change interval will result in machine damage.
6.4 Wheel Bearing
Pack the wheel bearing every 24,000 miles or every two years, whichever comes first. Use a good
grade of bearing grease.
6.5 Material Sensor Tube
Check for heat transfer oil in tube every 50 hours of operation. 2 ounces required.
6.6 Pump Packing Adjustment and Replacement
Material pump packing should leak a small amount (5-10 drops per minute) during normal use. If
packing adjustment is required, operate the pump under normal conditions before making any
adjustments. Tighten packing gland nuts evenly (1-2 flats on the nut) until there is 5-10 drops per
minute.
DO NOT OVER TIGHTEN packing gland as that will shorten the life of the packing and
wear out the sealing surfaces faster.
To replace packing, remove two nuts, packing gland clip, and packing gland halves. Use a packing
hook to remove all seven of the packing rings. New packing rings should be installed one ring at a
time, with the joints staggered 180° apart. Each ring should be seated firmly before the next ring is
installed.
The packing gland nuts should first be evenly tightened with a wrench to seat the packing firmly in
the stuffing box and against the shaft.
DO NOT over tighten the packing. The gland nuts should
then be backed off until finger tight. Follow adjusting pump packing at the beginning of this section.
