OPERATION

5. CONNECTING ATTACHING HEAD TO THE BOOM

The rotor unit can now be fitted to the end of the arms. The illustration shows the Rhino 1948 cowl bracket. Start the tractor engine and raise the second arm so that the mower head clamp is approximately 300mm (18 in.) clear of the ground. Place the mower head directly in front of the second arm. Level up mower head with wood packing. Remove clamp bracket (A) from the end of arms. Adjust position of the arms until the mower head clamp is lined up with the clamping bar on top of the rotor unit in the desired position along the bar. Replace clamp bracket (A) and nut and washers (B). Tighten fully. Note: Additional support may be needed at the end of the Boom to aid in installation.

5.2 Connecting Mower Head Hydraulics

Attach the 1" hoses, from the articulating arm to the hydraulic motor on the head. Use recommended hose end torque values in chart below.

-4	1/4	140	12
-6	3/8	230	19

* Straight threads do not always seal better when higher torques are used. Too much torque causes distortion and may lead to leakage.

DANGER! Do not operate this Equipment with hydraulic oil leaking. Oil is expensive and leaking oil could present a hazard. Do not check for leaks with your hand! Use a piece of heavy paper or cardboard. High- pressure oil streams from breaks in the line could penetrate the skin and cause tissue damage including gangrene. If oil does penetrate the skin, have the injury treated immediately by a physician.
