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.
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. 23)
• The female annular ring is located around the accessory
input shaft. (Fig. 24)
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.
