Fuelling and refuelling:
Limited shelf life of fuel
The fuel in the tank of the portable fire pump must be utilised within six
months. Otherwise deposits (sediments and precipitation) can occur.
The fuel in the fuel canister is to be changed at least twice a year
(depletion or replacement), because conditions for storage (vibration,
high temperature fluctuations) reduce the knock resistance of the fuel.
Change fuel
If the fuel should be changed in the tank, make sure that there is no mixing
of various sorts of fuel.
Deplete fuel in tank, or extract with a suitable pump.
Always use a freshly filled fuel for performance checks to prevent perfor-
mance losses.
7.11.1 Fuelling operation when engine is running
Before refuelling:
► Verify if it is necessary to refuel (e.g. by observing fuel warning lamp).
► Check the immediate environment and create as much space as pos-
sible. (Free space for unhindered escape from the danger zone must
be ensured).
► Fuelling is prohibited in a horizontal radius of 0.5 m to the filler neck
and vertically to the ground if an ignition source is present.
► Ensure that a deployable fire extinguisher (fire classes A and B, mini-
mum size 5 kg) is available.
► When refuelling, filling aids (fuel canister with filler) must be used.
► A second qualified person must be present during fuelling operations,
in order to help in the event of an emergency.
► For refuelling, make sure that the angle of inclination of the portable
fire pump is less than 15° from the horizontal.
► Ensure there is adequate lighting.
► The covering hood must be closed. The air flow blows dangerous
fumes away from hot spots.
