Recommendations

Very little service will be required by your pump if you follow the steps below:

1. Never Start Pump if the pump itself if not completely submerged in oil
2. Always use the cutting oil recommended by Autoclave Engineering. The Viscosity and Density are very important.
3. Never Start the pump if oil is mixed with water or ice
4. Never operate the pump if the oil temperature is below 20 degrees ( there is a heater for this scope).
5. Always make sure that screen protection (tank) is in good condition to avoid that drilling chips entering inside the tank and then in inlet of the pump.
6. If possible, avoid frequent start and stop of the pump.

 If, for any reason, the unit should fail to operate, follow the suggestions listed below:

1.  Disconnect pump from electric current. Try it at another electrical outlet to make sure current is getting to the unit. If it still does not start:
2. Remove the intake screen.
3. Remove three (3) front screws as indicated by the arrows in Figure 1 and then remove the volute (cover over the impeller). (Do not remove other screws which may be exposed.)
4. Lightly clean any corrosion or debris which may have clogged the volute or impeller. Use a brush and penetrating oil and lightly scrape away any deposits. Do not scratch the painted surface.
5. Turn the impeller by hand to make sure it turns freely. While keeping the impeller from touching any thing, plug the unit in to see if the impeller will turn.
6. If it does, re-install the volute, three (3) screws and inlet screen.
7. This machine is designed to be operated under clean and dry conditions. Operating environment temperatures should not be below 32°F (0°C) or greater than 100°F (38°C).

If for any reason these operations do not restore the pump to full service, contact the little Giant Pump Company or it's authorized service center, or you can contact us directly to try to resolve the issue.
