Daily maintenance of the pump
−
Check the oil level of the pump.
Note
If the oil in the pump drive has become whitish in colour, replace the oil. The whitish colour 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.
−
Check the vacuum above and below the filter in the stone catcher using the two vacuum
gauges on the stone catcher. A difference between the two readings indicates restriction of
the filter, in which case it must be cleaned.
−
Clean stone catcher in following steps
1. Open top cover of stone catcher unscrewing two 24mm nuts, carefully take off cower (1).
2. Look inside, if dirty clean out all obstacles.
3. Place back cover and tighten it up.
