Models 247444, 247574, 247456, 247457, 247970

(See FIG. 4, page 8.)

1.Disable hydraulic supply to Pump (D) by isolating it from the high pressure hydraulic supply using Ball Valve (AA).

2.Do one of the following:

Open Pressure Reducing Valve (S) to reduce trapped hydraulic pressure,

or

Cycle the timer to open the 3-way solenoid valve to reduce trapped hydraulic pressure.

Gauge on control module should read zero pres- sure after performing this step.

3. Disconnect power from Lubrication Controller (J).

1.Disable hydraulic supply to Pump (D) by isolating it from the high pressure hydraulic supply using Ball Valve (AA).

2.Disconnect power from Lubrication Controller (J).

3.Place a container under plastic tube (5g, page 16) in Pressure Relief Kit (247902) to catch fluid when relieving pressure.

4.Open ball valve (5d, page 16) in Pressure Relief Kit (247902).

Start-up

(For these instructions see FIG. 4, page 8.)

Do not insert finger into the overflow port while filling a reservoir equipped with a follow plate. Injury or amputation could result.

Prime Vent Line Models 247444 & 247574

The first time the reservoir is filled, use the vent valve outlet. This removes all air from the vent line (V).

1.Connect lubricant supply hose from remote filling station pump unit to outlet of Vent Valve (U).

2.Remove plug in Fill Port (K) located at bottom of reservoir.

3.Slowly turn on supply lubricant until lubricant appears in fill port.

4.Remove lubricant supply hose from vent valve.
