Hydraulic Operation - Manual

To ease removal and installation of the couplers, relieve the pressure in the system.. Securely support the implement.. Make sure no one will be injured by moving equipment when relieving pressure in the system.. Move the control switch to the float position with the engine running.. This will relieve the pressure.. Turn the engine off with the control switch still in float.. After the engine is shut down return the control switch to the neutral position.. The couplers can now be connected or disconnected with minimal pressure and effort..

When using a double-acting cylinder, connect the supply hose from the cylinder to the extend/raise coupler (right side) and the return hose to the retract/ lower coupler (left side).. To extend a double-acting cylinder, pull the remote lever rearward to position (1).. To retract the cylinder, push the control lever forward one position from neutral (2)..

When using a single-acting cylinder, connect the supply line to the right coupler.. To extend the cylinder, pull the remote lever rearward to position (1).. To retract the cylinder, push the control lever forward one position from neutral (2)..

To disconnect the coupler, make sure that the remote control lever is in the neutral position and the engine is off.. Check to be sure that the implement has its transport stops in place or is lowered to the ground..

Grasp the coupler tip behind its hose connection and firmly pull the connector out of the coupler.. Replace the dust cover on the coupler and cover the tip of the hose with a protective cap to minimize contamination..

WARNING: HYDRAULIC FLUID ESCAPING UNDER PRESSURE CAN PENETRATE THE SKIN CAUSING SERIOUS PERSONAL INJURY. WEAR GLOVES AND PROTECTIVE CLOTHING WHEN SERVICING HYDRAULICS. BE SURE THAT ALL CONNECTIONS ARE TIGHT AND HOSES AND LINES ARE UNDAMAGED.

Bleeding Remote Cylinders

When connecting a cylinder with trapped air (i..e.., a new cylinder, one that has been out of service, or one that has had the hoses disconnected), it will be necessary to bleed the cylinder to remove the air..

With the hoses connected to the remote control valve couplers at the rear of the tractor, position the cylinder with the hose end uppermost and extend and retract the cylinder seven or eight times using the remote control valve operating lever.. Check the hydraulic tank oil level before and after operating the remote cylinder..
