Fuel System Precautions
a. When priming or checking the fuel injection pump timing,
care must be taken to wipe spilled fuel from the outside of
the engine.
b. Always fit a new joint when a union has been disturbed.
c. Special care must be taken to see that there is no leakage from
the joints of the fuel pipe connection to the pump.
d. When tightening or loosening the fuel injection pump
delivery connections, use two spanners to prevent the un-
sealing of the fuel pump delivery valve holders.
e. When refitting the fuel pipe from the pump to injector, the
connection to the injector must be tightened before the
connection to the fuel pump.
This procedure will ensure that there is no leakage from
these joints.
f. It is most important that all fuel joints are tight and leak
proof.
g. Always fill the fuel tank through a fine strainer, preferably at
the end of the engine work period.
If any sediment is stirred up during the process this has time
to settle before the engine is used again, this will minimise
the risk of condensation contaminating the fuel. If cans are
used, avoid tipping out the last few drops.
h. Funnels are very difficult to keep clean in dusty conditions.
Wash them before and after use and wrap them up when not
required, or fill the tank direct from a small mouthed screw
capped fuel can.
i. The fuel injection equipment is manufactured to very accurate
limits and the smallest particle of dirt will destroy its efficiency.
Fuel free from water and contaminants is of the utmost
importance.
Precautions for Oil, Filters and Elements
a. Used liquid filters and elements contain some of the filtered
liquid and should be handled and disposed of with care.
b. After handling new or used elements the users hands should
be thoroughly washed, particularly before eating.
c. Fuel and new or used lubricating oil may cause skin
irritation.
Contact with used lubricating oil can cause cancer, birth defects
or other reproductive harm.
d. The materials used in the manufacture and treatment of some
filters and elements may cause irritation or discomfort if they
come into contact with the eyes or mouth and they may give
off toxic gasses if they are burnt.
e. Extreme care must be taken to ensure that waste oil, filter
elements, solvents or other toxic wastes are disposed
of in accordance with local regulations to prevent
contamination.
f. As a direct result of combustion the lubricating oil may contain
harmful acids and therefore it should not be left in the sump
if it is known that the engine will not be used for extended
periods.

Oil Seals Containing Viton
Some engines may be fitted with seals or 'O' rings
manufactured from ' V iton' or a similar material.
When exposed to abnormally high temperatures, in
excess of 400°C (752°F) , an ex t remely corrosive aci d
is produ c ed which canno t be remov ed from the skin .
If signs of decomposition are evident, or if in doubt,
always wear disposable heavy duty gloves.
