6.0 START UP PROCEDURE
The following start up procedure is complete and does repeat instructions on filling the gearbox and
pump.
6.0.1 Remove backpressure spring, if any (anti-siphon spring, Part#100198 on Fig 3) for start up.
Reinstall after pump is operational if needed.
6.0.2 Flooded Suction: Refer to Section II, Paragraph 1.0.9, for instructions on filling gearbox with
hydraulic fluid.
6.0.6 On initial start-ups: Set the pump capacity at 0%.
Check for proper motor rotation (Refer to Paragraph 1.0.6).
6.0.3 Open air bleed port (#51 on the drawing). Let all the air escape from the oil side. Keep it open
until only oil comes out from the port. Close the port tight. Run pump for 10-15 seconds couple
of times and listen for any abnormal motor or crank noises, and if present, refer to trouble
shooting chart.

6.0.4 Make sure that the pumping chamber is flooded by loosening Discharge Cap (Part#002073 on
Fig 3) and allowing solution to appear. Then tighten Discharge Cap (Part#002073 on Fig 3).
This procedure will also allow air to vent from pumping chamber. THE “dia-PUMP” WILL NOT
FUNCTION IF AIR IS TRAPPED IN THE HYDRAULIC FLUID OR LIQUID INSIDE OIL PUMP
CHAMBER.
6.0.5 After having let pump stand for 30 minutes and having rechecked fluid level, set pump capacity
indicator at approximately 30%. Be certain that pump suction and discharge lines are open.
6.0.5 Start pump. Slowly adjust to the required capacity.
