REMOTE HYDRAULIC CONTROL SYSTEM (IF EQUIPPED)
• Forcing oil through the relief valve for extended
periods will overheat the oil.
• When using the tractor hydraulic system to
power the front loader, do not operate the boom
and bucket cylinders simultaneously.
NOTE :
• To use the single-acting cylinder with the float
valve, connect this cylinder to the (C) port.
To extend a single-acting cylinder, pull the
remote control valve lever rearward. To retract a
cylinder, push it fully forward to the "FLOAT"
position. Do not hold it in the down position or
the transmission fluid may overheat.

WARNING
To avoid personal injury or death:
• Stop the engine and relieve pressure before
connecting or disconnecting lines.
• Do not use your hands to check for leaks.
Connecting
1. Clean both couplers.
2. Remove dust plugs.
3. Insert the implement coupler into the tractor
hydraulic coupler.
4. Pull the implement coupler slightly to make sure
that the couplers are firmly connected.
Disconnecting
1. Lower the implement to the ground to release
hydraulic pressure from the hoses.
2. Clean the couplers.
3. Relieve pressure by moving the hydraulic control
levers with the engine shut off. To release the hose,
pull it straight from the hydraulic coupler.
4. Clean oil and dust from the coupler, then replace
the dust plugs.
NOTE :
• Your local Kubota dealer can supply parts for
adapting couplers to hydraulic hoses.
