Daily maintenance of the pump
−
Check the oil level of the engine and pump.
Note
If the oil in the pump drive has become whitish in color, replace the oil. The whitish color may
indicate the presence of excessive condensation water in the oil.
−
Check for possible leaks in the oil and fuel hoses.
−
Check the dripping of the gland packing on the
piston rod; this should not exceed one drop every
five seconds. It may be necessary to readjust the
gland packing at greater lift heights.
−
Check that the dripping water can drain away from the gland packing. The channel must not be
plugged on the outside by dirt and sand that have splashed onto the enclosure.
−
Check whether the machine is still placed properly on the ground on which it stands, in accordance
with the instructions. This is important, because the situation can change as a result of a build-up of
sand/soil around the pump unit.
Checking the water trap
The intervals at which you should check the water trap depend entirely on the amount of water in the
fuel and the care taken when refueling.
- Unscrew the bottom of the water trap about 2-3 turns.
- Capture the draining water and fuel in a transparent (glass) vessel. Since water has a greater
specific gravity than diesel fuel, the water emerges before the diesel fuel. The two substances
separate at a clearly visible line.
- As soon as only diesel emerges from the opening, the bottom of the water separator can be
tightened again.
