5. Safety features (if fitted, see specifications table)
5.1. Oil cut-out
This mechanism is designed to prevent any damage to the engine resulting from lack of oil in the engine sump. It automatically cuts
out the engine. If the engine stops and will not restart, check the engine oil level before looking for any other cause of the problem.
6. Maintenance schedule
6.1. Reminder of use
The maintenance interval frequency and the operations to be carried out are outlined in the maintenance programme.
However, it should be added that it is the environment in which the pump unit is operating which determines this programme.
Accordingly, if the pump unit is used in extreme conditions, shorter intervals between maintenance procedures should be adopted.
These maintenance schedules apply only to pump units running on fuel and oil, that conform to the specifications given in this
booklet.

7. Maintenance procedures
7.1. Cleaning the air filter
Danger
Never use petrol or solvents with a low flash point for cleaning the air filter element as this could result in a fire
or explosion.
n
Remove the wing nut (No.1, Fig. D) securing the air filter cover (No.2, Fig. D), then remove the cover.
o
Remove the wing nut attaching the filter.
p
Remove the assembly consisting of foam (No.3, Fig. D) and paper elements (No.4, Fig. D) and separate them. Check carefully
that the two elements are not torn or pierced. Replace them if they are damaged.
q
Foam element:
A)
Wash the element in a solution of household cleaning product and warm water, then rinse thoroughly, or wash it in non-
flammable solvent or a solvent with a high flash point. Allow the element to dry completely.
B) Soak the element in clean engine oil and remove the excess oil. If there is too much oil remaining in the foam, the engine will
emit smoke when it is first started.
r
Paper element:
Tap the element lightly several times on a hard surface to remove excess dirt, or send compressed air through the filter, from the
inside outward. Never try to remove dirt using a brush. Replace the element if it is too dirty.
s
Carry out refitting following the reverse procedure to that used for removal.
