Maintenance
Clean the engine and pump assembly regularly, checking for any loose
bolts etc. Lubricate linkages with a general purpose oil or grease as
appropriate. The engine is lubricated internally by the 2-stroke fuel.
Clean the air filter at least every 30 hours of operation; more frequently if
the pump is used in a particularly dusty environment. Remove the air filter
cover and the air filter element, and wash the filter in petrol or paraffin.
Check the spark plug gap, and clean the electrodes, every 50 hours of
operation. The spark plug gap must be 0.6 -0.7mm.
Occasionally remove the exhaust silencer and shake out any rust flakes
which may be loose inside it, and check that the fuel filter is clean.
Storage
Clean the pump and engine, and drain the pump completely. Drain any fuel
from the carburettor and fuel tank, and store the pump in a clean and dry area.
Additionally, if the pump is not to be used for some time, remove the spark
plug and pour 2 or 3 teaspoons full of oil into the cylinder through the spark
plug hole. Pull the starter recoil rope slowly 2 or 3 times to allow the oil to coat
the internal parts of the engine, and replace the spark plug.
Troubleshooting
CAUTION: Do not run the pump dry as damage can result.
If your CD1fails to pump check that:
1. The pump is primed - prime the pump by removing the vent plug and
filling the pump casing with water.
2. The suction pipe is in water.
3. The suction filter (if fitted) is not blocked.
4. The suction hoses are not blocked or collapsed.
5. All suction pipe connections are airtight.
6. The discharge pipe is not blocked.
If the engine fails to start, or runs erratically, check that:
1. There is fuel in the tank.
2. The fuel is mixed at the correct ratio (20:1 petrol to 2-stroke oil).
3. The fuel cock is fully opened.
4. The spark plug is clean and the gap is correctly set.
5. The air filter is clean.
6. The fuel filter is clean.
