General Maintenance Guidelines
The India Mark II deep well hand pumps are to be properly maintained to ensure safe pota-
ble drinking water to the community, without break down. Proper and regular maintenance
will prevent breakdowns as seen earlier in the booklet. The moving parts in the India Mark II
hand pump above and below the ground level are few and therefore
simplifying
the mainte-
nance of the hand pump.
The following schedule of maintenance has been drawn at fixed intervals and has been ex-
plained more elaborately.
1) Once in 30 days:
(i) Tighten the handle axle nut and lock nut
(ii). Look for loose or missing flange bolts and nuts
(iii). Open the front of the head cover and clean inside the pump.
(iv) Check the chain anchor bolt for proper fitment. Tighten if necessary.
(v). Clean the chain assembly. Apply graphite grease.
(vi). Look for rusty patches and clean them.
(vii). Check whether the hand pump base is lose in the foundation. In case it is loose
an arrangement should be made to redo the foundation.
