GB-13RANSOMES HIGHWAY 2130SAFETY AND OPERATORS MANUALGB6 CONTROLS6.6 TRANSPORT LATCHESWhen transporting the machine ensure the cuttingunits are raised and the transport latches (A) areengaged.6.7 PARKING BRAKESThe parking brake (B) is engaged when the lever ismoved toward the operator. The brake is fitted witha micro switch that sensors brake position. Thebrake must be applied to start the machine, andwhen stopping and leaving the seat.CAUTION:- The parking brake must not beapplied whilst the vehicle is moving.6.8 HYDRAULIC LIFT LEVERSThe cutting units can be raised and lowered by threecontrol levers (A) situated on the right hand side of theoperators seat and can be operated as follows:Centre lever controls Rear Unit No. 1Right hand lever controls R.H. Unit No. 2Left hand lever controls L.H. Unit No. 3NOTE: If any unit is raised out of work then loweredinto work again the cylinder will not rotate until the mowfoot switch is depressed.To lift: Move the lever(s) upwards and hold in positionuntil the units are at the required height.To lower: Move the lever(s) fully downwards andrelease, the unit(s) will lower to ground level. DO NOThold lever in down position.NOTE: The units will only lift and lower when theengine is running.IMPORTANT: If, when cutting, a lift control lever isaccidently pulled up, the cutting units will not float overground undulations until the lever is pushed fully downand allowed to return to neutral again.6.9 UNIT COUNTERBALANCE CONTROLCutting unit ground pressure can be varied withinpreset limits and is controlled by the handwheel (B)on the right hand side of the operator's seat locatednext to the lift/lower levers. The handwheel isturned clockwise to reduce the groundweight of thecutting unit, improving slope climbing ability.The handwheel is turned anti clockwise to increasethe ground weight of the unit. Increased downpressure will reduce the likelyhood of cutting unitbounce when cutting undulating ground. Whencutting level ground the normal setting is midwayway between the maximum and minimum positions.
