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.
DC
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.
Highly inflammable!
!
Gasoline
Do not operate pump inside a well or pit.
There will be an exhaust gas build up and the pump will overheat.
Ensure good ventilation around the pump and do not operate
indoors.
Exhaust gases are very poisonous.
