Owner`s manual

Model 8720 / 8865 -24-
8.4.1.1. Prior To Use
A. Using the CV Zerk (Key #2) place 20 pumps of grease into the CV center housing. This should be
done with the driveline / CV as straight as possible.
B. Slowly articulate the double joint through its maximum joint angle several times.
C. Return the CV joint to its straight position and insert additional grease into the CV Zerk (Key #2)
until grease is evident around the housing and center sliding disk.
8.4.1.2. Normal Operation
A. Lubricate the following items after every eight (8) hours of operation. If short rows and frequent
turning or other demanding conditions exist, lubricate at four (4) hour intervals.
1. Cross and bearings (Key #1)-Add grease until it is purged around the seals.
2. CV center housing (Key #2)-Add grease until it is evident around the center sliding disk.
3. Telescoping members (Key #3)-Add grease until it adequately covers the sliding members.
Take apart occasionally to make sure adequate lubrication is being added.
4. Shield bearings (Key #4)-Add 2-3 pumps.
FAILURE TO FREQUENTLY GREASE THE CV CENTER HOUSING AND TELESCOPING MEMBERS
WILL REDUCE THE LIFE OF THE CV.
8.5. AUTOMATIC CHAIN OILER
WARNING: SHUTOFF AND LOCKOUT POWER BEFORE CLEANING, ADJUSTING, LUBRICATING
OR SERVICING THIS SPREADER. FAILURE TO HEED MAY RESULT IN SERIOUS PERSONAL INJURY
OR DEATH.
WARNING: HYDRAULIC FLUID ESCAPING UNDER PRESSURE CAN HAVE SUFFICIENT FORCE
TO CAUSE INJURY. KEEP ALL HOSES AND CONNECTIONS IN GOOD SERVICEABLE CONDITION.
FAILURE TO HEED MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
The automatic chain oiler attachment gives a squirt of clean oil to all roller chains every time that the spreaders
rear gate, hydraulic cylinder is activated. In this way, the spreaders roller chains get oiled in direct proportion to
the number of hydraulic cylinder cycles of the rear gate. This assures adequate lubrication.
New 30 weight oil, which is placed in the reservoir tank mounted on the spreader, is all that is needed to
properly lubricate all roller chains and sprockets. The automatic chain oiler does not use any oil from the
tractor’s hydraulic system. The hydraulic hose connected to the bottom of the oiler pump only serves to power
the piston in the pump every time that the spreader’s rear gate is opened.
Should the oil reservoir tank run dry, pour about a 1/2 cup of
clean 30 weight oil into the tank. Allow time for the oil to run
down into the oiler pump slowly and allow air to escape. After
thirty minutes to one hour has passed, finish filling the reservoir
tank. Make sure that all fittings and brackets are tight when
finished filling the tank.
While running the tractors hydraulics only, open and close the
spreaders rear gate several times. This will cycle the hydraulic
cylinder leading to the oiler pump. Keep cycling until oil can be
seen in all of the oil lines leading to the oiler brushes. (If you
experience problems priming the oiler pump, you may need to
bleed air out of the hydraulic hose where it is connected to the
pump. Crack the fitting until oil comes out, and then re-tighten.)
The hydraulic cylinder that the oiler pump is tied into is double
acting and must reach 300 PSI of pressure to actuate the pump.
