- Maintenance work for engine and pump - Maintenance work for canal system

- To obtain skill and knowledge on maintenance work for engine and pump - To obtain skill and knowledge on maintenance work for canal system - To obtain skill and knowledge on maintenance work for pipeline system

- Maintenance work for pipeline system

Farmers: How they repair or clean the altornator and starter motor?

Study Team: Study Team demonstrated how to do that.

Study Team: Those works should be done by a mechanic. Farmers are advised to call mechanic of ADD. Farmers: How to deceleration and acceleration of the engine?

Farmers: Is it better to replace PVC pipe of gully crossing to aluminum pipe to avoid daage by UV and to strengthen. Study Team: It is better to install additional aluminum pipe to increase flow capacity. Farmers: Is it better to dig out the pipes and place them on the surface?. Study Team: If it is fixed to the ground, it is possible. However it is not recommendable because of safety of pipes.

- To keep operation and maintenance record. - To protect foundation of gully crossing with clay plastering. - To excavate drain ditch at gully crossing in order to avoid running water scour the foundation of canal.. Farmers agreed to try to do above items.

Farmers: what causes engine revolution to maximize or minimize

-Farmers should a protection bund on the upland of the main canal. -They should add more oil to the air cleaner before running the engine.

Farmers: when to replace diesel filter Mechanic: when the engine is jerking while running and also replace filter annually or after six months depending on irrigation ho

Mechanic: unneccesary adjustment of of the accelerator throttle knob by either children or adults8. Recommendation for Farmers' Group by Counterpart

Farmers: worry concerns on the diesel filter seal as it has been leaking for a long time and causes a lot of fuel wastage Counterpart: Mechanic said that the only solution is to replace with a new seal. Farmers: Is it possible to use car bostic paste on the seal?

-Farmers knew the importance of water in the supply pipe before starting the engine.

-Farmers knew how to check if diesel is being pumped or not.


9. OthersPlanting starts on Monday 25th August 2008.

- Recording of all pump proceedings. - Stabalising the engine position and continuous supervision at the engine site. - Oil and fuel check up need illustrated. -Water availability in the supply pipe before starting the engine.

Farmers worry about the engine breaking sound some seconds after starting was responded to by the mechanic as some signs of airlocFarmers are not comfortable with the canal structure, looking dip as compared to Chiwozas and fear will consume a lot of fuel to use itFarmers agreed not to use the canal structure but improvise their own earth canal to used during this dry planting.

-Farmers knew how to check all necessary pump parts before operation

- Farmers knew how to operate the engine

- Farmers knew how to record all pump expenditures in irrigation period

All pipes should be taken care of in changing to reduce damages.

The Delivery pipe was changed from one pump to the other because the former pipe could not hold the leaflet well.

Pipes alined from the intake direct to the lined canal will be removed and used to deliver water to earth canals.

Farmers minds are already set on using earth canal to save fuel hence advised to do so but still care for the lined canal.Farmers should find enough fuel to test the lined canal before making conclusions that it can not work.
