Rephasing Groove
Hydraulic oil moves from one cylinder to the next through and indentation in the cylinder wall known as a
'rephasing groove'. When the cylinder is fully extended this groove creates a bypass over the piston main seal,
allowing oil to flow to the next cylinder in the set. Since these grooves are quite small it will often take a number
of minutes for oil to completely circulate through the set of cylinders.
On initial startup of a phasing cylinder system it may take a number of minutes to force oil through the system
and purge out any air in the hydraulic lines. During normal operation small amounts of oil may leak past piston
seals causing cylinders to fall out of synchronization. Synchronization can be restored by fully extending
cylinders and holding the circuit open for period of time.
TRANSPORT LIGHTS
Use FLASHING WARNING LIGHTS when traveling on public roads day or night, unless
prohibited by law.
If the rotary cutter obscures the tractor warning or tail lights, the rotary cutter MUST be equipped with a
transport light kit.
Check local highway regulations concerning moving machinery on highways
Installation of Lights
Lock the rotary cutter into transport position. Bolt
the light frames to the center beam using the
supplied 3/8" bolts, washers and locknuts.
Install the lamps onto the light frames with the
amber light to the outside of the cutter. The red
lamp is to be installed with the red facing the rear.
Install the light module on the right light frame.
