1. Press and hold ENTER.
2. Press the up or down arrow on the Diagnostics keypad to increase or decrease brightness.
3. Release the ENTER button when the desired brightness is attained.

Tools: jack screws

1. Loosen the four hand knobs and tighten the four jack screws to open the wear plate clearance.
2. Re-tighten the hand knobs.
3. Measure the adjustment distance by comparing the before and after gap between the adjustment flange and the volute casing.

⚠ If the impeller continues to rub on the wear plate, repeat the adjustment procedure

Tools: jack screws, wrenches

1. Re-grease O-ring and install rotating assembly into volute; installation is the reverse of removal.
2. Evenly tighten rotating element bearing housing fasteners until impeller lightly contacts wear plate.
3. Tighten bearing housing jack screws until .010 to .020 in (.25 to .50 mm) increase in clearance is achieved.
4. Rotate shaft and verify no impeller/wear plate contact or rubbing.
5. Tighten the jack screws at each corner of the bearing housing, then tighten the jack screw lock nuts.

⚠ If a manual shutoff valve is installed in the discharge line, it must not be left closed during operation

⚠ The pump will not prime when dry; extended operation of a dry pump will destroy the seal assembly

⚠ Never open the priming cover on a pump that is hot or that has been operated recently

1. Disconnect the pump from the tow vehicle, chock the wheels to prevent rolling.
2. Lower the rear leveling jacks and adjust until the pump is as level as possible.
3. Attach fittings to intake and outlet openings; ensure gasket/seal is in place and tighten all hardware.
4. Attach a rigid hose to the intake (suction) side; suction hose/piping should be at least as large as the pump flange.
5. Attach a rigid intake screen or strainer to the end of the suction hose.
6. Place the intake hose into the liquid; submergence should be four to five times the pipe diameter.
7. Attach a flexible hose to the outlet (discharge) side; use a concentric taper to increase discharge diameters.
8. Check intake and outlet hoses for sharp bends or kinks; intake hose should slope upwards toward the pump.
9. Fill the pump casing half full with liquid to prime; replace cover and tighten clamp screws hand tight.

Tools: Torque wrench

1. Disconnect the engine starting battery.
2. Remove the generator fan guard.
3. Torque each of the drive plate bolts to 46 ft-lbs (49 Nm).
4. Reinstall the generator fan guard. Reconnect the battery.

Tools: Grease gun with standard fitting

1. Remove the small rubber plug on the grease cap.
2. Attach a standard grease gun fitting to the grease zerk fitting.
3. Pump grease into the fitting until new grease is visible around the nozzle.
4. Use only high quality grease made for wheel bearing lubrication.
5. Wipe excess grease from the hub with a clean cloth.
6. Replace the rubber plug when finished.

⚠ Over-filling with oil can result in premature failure of bearings

1. Prior to starting the pump, remove the seal vent plug and fill the seal cavity with approximately one quart (33 oz) of ISO VG 32 turbine oil.
2. Fill the seal cavity so the oil level is halfway in the level sight gauge.
3. Maintain the bearing housing oil at the middle of the sight gauge.
4. Use an ISO viscosity grade 32 turbine oil and fill through the air vent hole at the top right of the bearing frame.
