1. PUMP SPECIFICATIONS

Thank you for choosing Dayliff DC engine pump. Both pump and

engine have been manufactured to the highest standards and if

operated correctly should give many years of efficient and trouble

free service. Careful reading of this instruction manual is therefore

extremely important and if you have any queries please refer them to

your retailer.

DCI

The DAYLIFF DC range of self priming engines pumps are of fully portable design

suitable for irrigation, dewatering and general pumping duties.

All pump bodies and impellers are manufactured from high grade cast

aluminium. Also included are quick-couple hose connectors and suction

strainers. Maximum suction is 8m at sea level, though this will be reduced at

altitudes.

All models feature open impellers suitable for pumping lightly silted water and a

sturdy carrying and protection frame.

DCX

High specification high pressure pump with option of single or twin impeller.

DCT

Robust diesel pumps for pumping polluted water and sewage.

DCI

Cast iron engine pumps for heavy duty dewatering.

DCI 80D

WARNING

Note that performance curves relate to the engine governor set

at maximum speed to achieve maximum rated power output.

To prolong engine life pumps should only be run under

maximum power conditions for short periods and for extended

duty the throttle setting should be reduced to approximately

three-quarters power. Pump performance will then be

reduced accordingly.

· Ensure the suction hose is of the rigid type and it should be of the same

diameter as the pump inlet and fitted with the correct connectors.

· Connect suction hose to the pump as indicated.

WARNING

Airtight connection of the suction hose is essential or suction

prime will be lost and the pump won't operate.

3. PUMP OPERATION

· CHECK ENGINE OIL. Operating without oil will

cause severe engine damage and invalidate the

warranty.

· Fill the pump chamber to overflowing with water

through the priming port. Insufficient water will

cause pump damage and limit suction

performance.

· Check that the suction hose strainer is immersed in

water and above the water source bed to avoid sucking mud, silt or sand.

The foot valve must be set not less than 300mm below the water surface.

· Ensure the delivery hose is unimpeded and laid without obstruction or kinks

to the delivery point .

· Start engine by pulling starter cord. Ensure ignition switch ‘on’, fuel valve ‘on’

and throttle at max speed. Close fuel valve whenever pump is not operating.

! Suction lift should be minimised to obtain maximum pump performance.

Maximum suction lift is 8m at sea level, though for acceptable pump

performance it should be limited below 4m.

· Ensure the delivery head is within the performance capacity of the pump (see

pump curve).

4. ROUTINE MAINTENANCE

For Diesel pumps see separate engine manual. The below instructions apply to

petrol versions only.

ENGINE OIL

Check engine oil daily. If low refill with SAE30.

Change engine oil after first month or after 20hrs operation and thereafter every 3

months or 50 hours of operation, in both cases whichever is sooner.

AIR CLEANER

Check the air cleaner every 3 months or after 50 hours operations, whichever is

the sooner. Clean by blowing away accumulated dust and soaking in kerosene.

SPARK PLUG

A correctly set spark plug in good condition is essential for efficient engine

operation. Check the plug every 3 months or after 50 hours operation, clean with

a wire brush and set the electrode gap to 0.7-0.8mm. If general conduction is

unsatisfactory it should be changed with a NGK (BPR5ES) or similar.

PUMP HOUSING

Drain water from pump housing after use by releasing the drain plug.

5. SAFETY WARNINGS

Do not restrict the exhaust silencer.

There is a danger of overheating and fire.

Read and carefully understand the Instruction Manual before

before use.

Instruction

Manual

Ensure a competent trained person is used in case of overhaul.

Do not use pump on a slope.

Fuel spillage may occur and cause a fire.

Keep children away from pump when in operation.

Avoid proximity to fire when refueling.
