Selective Control Valves - Oil Withdrawal with Hydrostatic Drive (with PC Hydraulic System)

LX1045800-UN-22DEC10

IMPORTANT: Never regulate the flow rate by means of an external valve. Always use flow control valves (A).

Maximum obtainable flow of transmission/hydraulic oil is dependent on the size of the hydraulic pump installed on the tractor.

Pump size	Flow rate
28 cm3 (1.7 cu.in.)	68 l/min (18.0 gpm)
35 cm3 (2.1 cu.in.)	80 l/min (21.1 gpm)

Shut off the engine. Connect hydraulic hose of hydrostatic drive. Comply with the symbols on the couplers.

IMPORTANT: Connect implements with hydrostatic drive to Series 450 SCVs only for operation.

Start the engine. Move the control lever to retract position. To switch off the hydrostatic drive, move the control lever to the float position. Shut off the engine and take out the hydraulic hose.

IMPORTANT: Do not move the control lever to the neutral position, as this may result in back-pressure causing damage to the hydrostatic drive and hoses.

IMPORTANT: While driving, oil withdrawal for hydrostatic drive is restricted. See Specifications, Tractor Operation at Maximum Inclination.
