Start-up Instructions:
1.Read all safety instructions. Decals on the
2.Before operating, read all the safety and operating instructions in the Operator's Manuals for both the tractor and mower.
3.When the hydraulic tank has been filled, The Pump Suction Hose filled with Hydraulic Oil and the mower unit (Head) properly assembled, the unit should be started up. NOTE: Make sure that no materials, tools, or jacks have been left under the mower head. Make sure the front and rear of the mower are properly guarded to prevent any foreign objects from being thrown by the mower. All other workers should be kept a safe distance from the unit before the mower is started.
4.Start the tractor and idle at a slow engine speed until oil is being pumped. Check for any leaks, this is easiest with an assistant watching for leaks. Do not run if Oil is leaking.
5. Bleed the air out of all hydraulic cylinders one at a time by extending them to their full length. DO NOT SWING THE BOOM till last and you have gone to the Rest Stop and Support Section for instructions.
6.Engage the Cutter Control Valve at low engine rpm and run the mower slowly for a short period until all air is removed from the hoses. Keep all persons WELL CLEAR of mower since Blades can THROW OBJECTS with great velocity for a considerable distance! KEEP CLEAR!
7.Run the mower at a low tractor engine speed until the mower Hydraulic Sytstem gets the Air out off it. Operate at an engine speed that keeps the filter restriction gauge reading in the "Green Zone". With the hydraulic warm, bring the tractor speed up to normal operating speed. If the filter gauge reads in the red zone, stop the unit, release all hydraulic oil pressure, and Check the filter element in the tank mounted filter or any Hose that may be kinked. Restart the tractor and mower unit and again check the filter gauge (oil must still be hot).
8.If the filter gauge reads in the red when first started and does not drop as oil warmss, then something is wrong, contaminants have been introduced into the hydraulic system or some thing connected wrong. You may need to repeat previous steps again until the gauge reads in the green.
9.Check the fluid level in the Hydraulic Tank and add oil if required. As the air has been forced out of the Cylinders and Hoses, it goes into the Hydraulic Tank and reduces the oil level. The Hydraulic Oil must be at least at the level of the Sight Gauge on the side of the Tank.
10.Basic trouble shooting guide for first start up.
A.Electrical solenoid valve does not work - check wiring, possible faulty switch, possible faulty solenoid.
B.Pump is making noise - check for obstruction in suction hose and tank suction assembly, check alignment of pump driveshaft.
C.Cylinders will not raise - hoses from cylinder incorrectly connected to valve bank, pump not suppling oil.
D.Cylinder rises slowly - hoses from cylinder incorrectly connected to valve bank, work port reliefs on valve bank set too low - replace as required.
E.Filter reads in red - viscosity of oil too high - wait until oil heats up before checking filter gauge. If gauge reads in red even after unit is hot, then the filter must be replaced.
