1. Deactivate the elevation slow stop circuit. (*1)
2. Loosen the part A of hydraulic pilot control valve
(main 2) 1 turn. Disconnect the self-seal joint for
auxiliary winch brake release hose. Raise the
boom fully.
3. Turn the PTO switch ON.
4. Move the auxiliary winch lever at its full stroke on
the hoisting up side while the elevating lever is
moved at its full stroke on the raising side.
5. In this state, set the engine speed to 2150 min
-1
and check the pressure.

6. After adjusting the pressure for winch hoisting up
(B), fully tighten the part A (loosened above (2.)).
7. Connect a pressure gauge to the pressure check
port (C) (*2).
8. Move the auxiliary winch lever at its full stroke on
the hoisting up side while the elevating lever is
moved at its full stroke on the raising side.
9. In this state, set the engine speed to 2150 min
-1
and check the pressure by the pressure gauge.
(*1): To deactivate the elevation slow stop circuit, disconnect the connector (CN124) (T2) of the elevation
proportional control valve. (After adjusting, connect the connector (CN124).)
(*2): The pressure check port (C) (winch hoisting up) and (L) (outrigger) are the same port.
