en-236 CONTROLS6.8 VARIABLE CYLINDER SPEED (B ) __________________________________The speed of rotation of the cutting cylinders isadjustable by means of the handwheel situated onthe right hand side of the operator to the rear of thecutting unit lift levers. Rotate the hand wheel clockwiseto increase cylinder speed, anticlockwise to decreasecylinder speed.6.9 HYDRAULIC LIFT LEVERS (C,D,E) _________________________________The cutting units can be raised and lowered by three controllevers situated on the right hand side beside the operatorand can be operated as follows:Centre lever (C) controls Centre and RH & LH front Units No. 1,2,3Right hand lever (D) controls R.H. Wing Unit No. 4Left hand lever (E) controls L.H. Wing Unit No. 5NOTE: If any unit is raised out of work then lowered into work again the cylinder will not rotate untilthe mow foot switch is depressed.To lift: Move the lever(s) rearwards and hold in position until the units are at the required height.To lower: Move the lever(s) fully forwards and release, the unit(s) will lower to ground level. DONOT hold lever in down position.NOTE: The units will only lift and lower when the engine is running.IMPORTANT: If, when cutting, a lift control lever is accidentally pulled up, the cutting units will not float overground undulations until the lever is pushed fully down and allowed to return to neutral again.6.10 UNIT COUNTERBALANCE CONTROL (F ) ____________________________Cutting unit ground pressure can be varied within preset limits and is controlled by the handwheel on the righthand side of the operators seat.The handwheel is turned clockwise to reduce the ground weight of the cutting unit and to improve slope climbingperformance.The handwheel is turned anticlockwise to increase ground weight of the cutting unit and this setting will reducethe possibility of cutting unit "bounce" when working at high speed on undulating ground. The normal positionfor this control is midway between the minimum and maximum settings.
