MAINTENANCE
1. Always maintain the pump in a clean condition, checking regu-
larly for loose bolts etc.
2. Clean the air filter once every 50 hours of use (or more often in
unusually dusty conditions) as follows. Clean the foam filter ele-
ment with domestic detergents and clean the mesh element by
knocking against a solid object or blow out any dust with a high
pressure air jet. Never operate the pump without the air cleaner
installed as this would cause premature wear to the engine.
3. Replace the spark plug after the first month or every 50 hours
of use. Check when installing that the spark plug has the cor-
rect clearance by measuring with a feeler gauge and adjusting
the side electrode as required. Clearance should be 0.70-
0.80mm. The recommended spark plug is RK34200/168F.
CHANGING THE OIL
The oil in the engine should be changed after the first 20 hours use
and thereafter every 6 months or 100 running hours. Remove the
dipstick and drain plug and then drain the oil. Re-fill and check the
level.
ENVIRONMENTAL PROTECTION
One of the most damaging sources of pollution is oil. Do not throw
away used oil with domestic refuse or flush down a sink or drain.
Take it to your local waste disposal site.
STORAGE & HANDLING
After use, drain the pump body whenever there is danger of free-
ing, and if the pump has been used with contaminated or salty
water, It should be thoroughly flushed with clean water following
use, both inside and out and drained before replacing the drain
plug. Always transport the pump with the fuel cock turned off and
keep the unit level to prevent any fuel from spilling.
If the pump is not to be used for some time, it should be flushed
thoroughly with clean water, and drained completely before storing
in a clean dry environment. Additionally, it should be prepared
as follows:
1. Drain the fuel tank and carburettor completely by opening the
drain plug in the carburettor float chamber and draining all
remaining fuel into a suitable container ensuring the fuel shutoff
valve is open.
2. Remove the spark plug, and pour 2-3 teaspoons of light oil into
the cylinder through the spark plug hole.
3. Pull the starter recoil rope slowly 2 or 3 times so that the oil is
deposited on the cylinder walls and replace the spark plug. For
longer term storage, use the starter to turn the engine until
the triangle mark on the starter wheel lines up with the starter
screw hole. In this location both the inlet and exhaust valves are
closed which may prevent the engine from suffering internal
corrosion during storage.
