4. Fuel Tank Filler Filter
Occasionally visually check the condition of the fuel tank filter
(when refuelling is ideal). If there is any sign of deposit build up,
remove the filter from the tank and clean.
• Clean the filter with environmentally friendly water based
degreasing agent and if necessary blow the fine mesh through
with clean, dry compressed air.
• Allow to dry thoroughly before refitting.
• When refitting ensure that the 2 cut outs on the top edge of the
filter line up with the cut outs in the fuel tank filler neck. (Fig. 23)
5. Annular Rings and Accessory Locating Pins
The annular rings ensure the precise mating of an accessory to the
EVO-SYSTEM Engine.
• The male annular ring is located around the engine output
shaft. (Fig. 24)
• The female annular ring is located around the accessory
input shaft. (Fig. 25)
The annular rings should be kept scrupulously clean, and checked
at every connection or disconnection. If any dirt or debris is found
it should be removed using a slightly damp soft cloth.
All other mating surfaces between engine and accessory should
be kept as clean as possible.
The three (3) locating pins and two (2) stabilising pins are
positioned on the accessory.
These pins should also be kept scrupulously clean and free from
dirt or other contamination.
A very light spray coating of silicone machine oil occasionally
applied to their surface will aid accessory connection.
A cover for coupling protection is provided with each accessory
and should be used whenever the accessory is 'remote' from the
engine. The engine is also supplied with a coupling protection cover.
This should be fitted whenever an accessory is removed.
6. Replacement of Plastic Annular Ring
The EVO-SYSTEM Engine (Male) annular ring can be replaced if
damage or wear is detected.
To replace the annular ring:
• Remove the damaged ring by carefully cutting through it with a
sharp craft knife.
• Clean away any dirt, debris or Plastic residue from the annular
ring mounting flange.
• Position the Plastic ring onto its flange and push it fully home so
that it lies flush against the engine casing.
