MAINTENANCE
LUBRICATION
Grease Points
All grease points shown in FIGURE 5-1 below should be greased before operating the machine. To make
greasing easier by relieving the weight form the pivot pins, rest the rotor unit on the ground, stop tractor
engine and operate control levers in both directions. Grease daily or every 8 hours of operation. Use a
high quality lithium base #2 grease.
Hoses and rotor drive circuit
It is false economy to try and make a damage hose last a bit longer, because a failure can spill several
gallons of oil on the road endangering traffic and costing money. To reduce the risk of this happening and
ensure a long life from the hoses follow instructions given below:
A. Check weekly that all hoses and their connections (with particular attention to the rotor drive
circuit) are in good condition and that there are no leaks or damage. B. Replace any hose that is
leaking or damaged.
C.
Ensure that hoses have not chafed against sharp edges. If they have, inspect damage and replace if
necessary.
D.
Re-route any hose that has been chafing.
E.
Ensure that when fitting hoses that they are fitted without kinks or sharp bends.
F.
Pay particular attention to the suction hose from tank to pump.
G.
If in doubt about the condition of a hose REPLACE IT.
HYDRAULIC OILS
Only use Universal Hydraulic Oil
Hydraulic Cylinders
It is advisable to check all cylinder caps for tightness occasionally and if found to be loose, tighten them
immediately.
Storage
Before removing the machine from the tractor, a thorough check of the machine should be made as
follows:
A.
Thoroughly clean all moving parts, particularly the rotor unit.
B.
Check that all flails are in place, and that they are in good condition.
C.
Check all hoses for damage, such as cracks, evidence of chafing and leaks.
D.
Smear all unpainted metal parts with grease and lubricate all grease fittings.
E.
Make a note of item that needs replacing so that parts can be ordered.
