ROTATOR MAINTENANCE
The rotator is capable of 360 degree continuous rotations for easy, accurate crushing at all
angles. The rotator is to be used only as a positioning features, not as a means of bending or
breaking material. Use of he rotation feature for any other purpose may damage the rotation
components and may compromise the attachment’s warranty.
The rotation mechanism consists of a hydraulic motor driving a turntable bearing. Periodic
maintenance requirements include maintaining proper bolt torque and lubrication, these items
are detailed below.
BOLT TORQUING
The bolts connecting the turntable bearing are important maintenance area. After the first
eight hours of use the bolt must be retorqued. Bolts be retorqued only once and then must be
replaced if they loosen due to fatigue caused by stretching the bolt during torquing. If the
bolts continue to loosen, contact the dealer or factory. These bolts should be inspected daily
and replaced after 1,500 hours or 12 months.
TURNTABLE BEARING LUBRICATION
Rotating attachments in storage should be lubricated at least every six months. Equipment
operating frequently in extreme environments should be lubricated at least every eight hours.
If old grease is noted to be in good condition and free of contamination, the interval may be
extended. Conversely, if the old grease is contaminated or deteriorated, the interval should be
shortened.
LUBRICATION PROCEDURES
Bearings Are equipped with 1 to 4 grease fittings, depending upon model used. The grease
fittings will be located either on the outside of the bearing or on the upper head side plate. It is
recommended to rotate bearing while greasing in order to uniformly distribute the grease and
to most effectively flush out the old grease and contaminants. The bearing should be turned
through two full revolutions while greasing through any one fitting. Continue greasing until
clean grease can be felt exiting at the seals.
TURNTABLE BEARING LUBRICANTS
For normal operating conditions, periodic lubrication with lithium Grade 2 extreme pressure
grease is recommended. For operation below 0
o
C (32
o
F), Grade 0 is recommended.
Comparable lubricants produced by other reputable manufacturers not referred below may
also be used.
