Every 8 hours:
1. Lubricate driveline:
Apply two or three shots of grease to the driveline cross and
bearings and the telescoping shafts. See the driveline manufacturer operator’s
manual for further information on the driveline.
2. Lubricate roller bearings and rotor support bearings (see fig. 6): Apply two or
three shots of grease to the roller bearings and to the rotor bearings on each side of
the machine.
3. Check gearbox oil level by removing the breather plug. Using a flashlight, check
inside the gearbox to verify that it is approximately ½ full. When filled correctly the oil
level should be approximately halfway on the input shaft. When fully drained gearbox
requires approximately 61 fl. oz. (1.9 qt.) of oil. If needed add SAE 90W gear oil.
Note: Never overfill gearbox. Oil will expand when hot. Overfilling will likely cause
excess oil to blow out of breather cap.
Every 25 hours:
1. Check hardware tightness;
shredder vibration can loosen bolts
11
. Check tightness
of the hardware periodically.
2. Check belt tension

.
DANGER: The beginning of abnormal vibrations from the rotor may mean it is out
of balance. A single broken or missing blade is enough to cause this. An
unbalanced rotor, due to its high rotation speed, can dislodge itself from the side
bearing supports thus damaging the shredder and cause serious injury to
persons nearby. Always find the source of the vibration. Bring the rotor back in
balance by replacing blades, removing wrappings, etc. If this does not remove the
vibrations, the rotor may have to be rebalanced at one of our Authorized
Company Dealerships.
4.03 - Blade Maintenance
WARNING: To avoid possible injury always wear proper eye and hand protection
when servicing shredder blade.
In order for the shredder to work properly, and to always obtain a precision cut with
lower HP requirements thus keeping cost down, proper blade maintenance is important.
Blades must be kept sharp, at their original length and corners maintained. A blade
must be replaced if, due to wear or damage, its original shape has been distorted.
Blades should be replaced when their total length is less than 5” or when the hole that
the blade bolt is assembled through has ovalized 5/64” over its original diameter
(see.
fig. 7) .
