6.3 QUICK COUPLER INSTALLATION
In order to attach the plow to a loader, follow these procedures.
Using the loader’s quick coupler, approach the plow with caution and hook onto it.
Make sure the locking pins are activated.
6.2 HYDRAULIC COMPONENTS
a) It is strongly recommended that all hydraulic components (fittings, valves,
cylinders etc.) be verified before initial operation. It is the owner’s responsibility to make
sure that all components are secure, operational and free of leaks.
b) Hydraulic hoses will need to be provided and installed from the loader to the
diverter valve. Hoses arriving from the loader must enter port A1, A2 or P1, P2 of the
diverter valve. Depending on model of valve these ports may either be on the left or the
right side of the valve.
(Fig.2)
c) Attached to the diverter valve is a wiring harness. Run the wiring up the loader arms
and into the cab. Depending on model chosen, install the controller
accordingly. In the cab, it will be necessary to hook up the wiring into an available and
adequate power source.
d) Required power source (either 12 or 24 volts) will be dictated by the voltage of the
coils.
e) The wiring harness includes a male/female sealed connector
(Fig.2.1)
. This connector
is useful when detaching the snow plow from the vehicle. It is strongly recommended to
add electrical grease on the connectors
(Fig.2.2)
. It is also imperative that the operator
takes care to prevent moisture from entering the connector. Safety caps with molded
rubber seals are included and must be used properly when coupling and uncoupling the
blade to prevent possible failure of the wiring harness.
f) The hydraulic wings are equipped with flow control valves. Is is important that these
valves are adjusted correctly to allow a smooth rotation of the wings.
g) Relief valves
(Fig.2)
are installed for protection of the hydraulic cylinders. These are
pre-set at the factory. It is not recommended to adjust these without prior approval from
Metal Pless. If adjustment is necessary, note that both ports of the relief valve must be
adjusted simultaneously for proper pressure relief of oil flow in either direction.
