MAINTENANCE

The actual speed at which the harmonic will occur will vary with each mower and each installation. To avoid

this harmonic vibration when operating the mower, it may be necessary to adjust the engine speed of the trac-

tor up or down.

Some units have a harmonic vibration which occurs below the nominal operating speed. On these units, it will

be noticed that there is always a little vibration at a particular RPM as the mower is being sped up to operating

speed. This occurs as the shaft passes through its normal harmonic vibration point. As long as the mower is

operated at the proper speed, then harmonic vibration will not be an issue.

1. Read all safety instructions. Decals on the Boom warn you of particular and multiple hazards. Many

decals are attached close to part of the Boom where there is a possible hazard. Read and make sure

you understand the safety messages before you operate the Boom. Keep all decals clean and read-

able. Replace lost or damaged decals.

2. Before operating, read all the safety and operating instructions in the Operators Manual for both the

tractor and mower.

3. When the hydraulic tank has been filled and the mower unit properly assembled, the unit should be

starte d up. NOTE: Make sure that no materials, tools, or jacks, have been lef t 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.

5. Engage the Cutter Control Valve at low engine PTO speed and run th e 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!

6. With the area clear of any groun d and overhead obstr uctions, work each cylinder on the boom one at a

time, several times, to expel any air in the Hoses and Cylinders.

7. Run the Mowe r Head for 5 minutes. While the tractor is idling, blocked, wearing protective clothing and

eye protection, CAREFULLY check for leakin g hydraulic fittings, ho se s and po rts at this point with a

piece of cardboard, DO NOT USE YOUR HAND! If any are found stop the tractor immediately and

correct any leaky connections.

8. Check the fluid level in the Hydraulic Tank on the Tractor, and add oil if required. As the air has bee n

forced out of the Cylinders and Hoses, it goes into the Hydraulic Tank and reduces the oil level.
