OPERATION

5.When pumping is complete, set the hydraulic­ control valve to the “OFF” posi­tion. Lift the trash pump from the work area using the rope or cable to avoid dam- age to the hoses or couplers.

IMPORTANT

Observe the following for trash pump protection

and care.

6.The trash pump must maintain a mini­mum impeller speed in order to move solid particles through the pump. While pumping liquids containing large sol- ids, monitor the flow from the outlet of the fire hose.

If it begins to slow, turn off the hydraulic power source and lift the trash pump from the work area. Disconnect the hydraulic hoses and clean at the wa- ter hose and the pumping chamber.

COLD WEATHER OPERATION

If the trash pump is to be used during cold weather, preheat the hydraulic fluid at low power source speed. When using the nor­mally recommended fluids, fluid should be at or above 50 °F/10 °C (400 ssu/82 centi- stokes) before use.

Damage to the hydraulic system or pump motor seals can result from use with fluid that is too viscous or thick.

IMPORTANT

Pumping liquids with a solids-to ­liquid ratio greater than 30 per­cent solids to 70 percent liquid will cause accelerated impeller wear.

7.To maintain optimum performance, it is good prac- tice to periodically inspect the impeller for wear or damage. This is especially important following the pumping­ of liquids containing sharp, abrasive solids.
