2. Turn the PTO switch ON

3. Fully retract the elevating cylinder.

4. Move the elevating lever at its full stroke on the lowering side.

5. In this state, check the pressure.

(*3): To deactivate the slow stop circuit, disconnect the connector (02) of the elevation proportional solenoid valve. (After adjusting, connect the connector (02).)

(*4): To deactivate the slow stop circuit, disconnect the connector (01) of the elevation proportional solenoid valve. (After adjusting, connect the connector (01).)

Adjusting Pressure (Hydraulic Pressure)

4. Steering [NOTICE]

Oil temperature: 50±5°C (113 - 131°F) (Hydraulic oil: TADANO Hydraulic Oil LL) Shift the control lever or switch while the engine is idling, then increase engine speed.

2. Turn the PTO switch OFF

3. Without jacking up, turn the steering to the right side. Gently move the steering cylinders to the end of the stroke.

4. In this state, set the engine speed to 2500 min-1 and check the pressure by the pressure gauge. (Note): Adjustment is not possible. If the pressure is out of the set pressure range, replace the priority valve.

Adjusting Pressure (Hydraulic Pressure)

5. Swing [NOTICE]

Oil temperature: 50±5°C (113 - 131°F) (Hydraulic oil: TADANO Hydraulic Oil LL)
