5.22.2 - Fuel storage conditions
(Fig. 51)
The utmost care must be taken to keep fuel clean.
1. Never clean the inside of containers of other fuel sys-
tem components with a fluffy cloth.
2. Bulk storage tanks should not be too large: approxi-
mately 10,000 litres.
3. The storage tank should be under cover and supported
on a cradle high enough for the tractor fuel tank to be
filled by gravity. It should have a suitable manhole to
provide access for cleaning. The outlet tap should be
about 75 mm above the bottom of the tank to allow
water and sludge to settle. It should have a removable
strainer. The storage tank should have a fall of about 4
cm per metre towards the rear (drain plug side).
4. Let the fuel settle in the storage tank for 24 hours
before use after any maintenance or refilling the tank.
5. Clean out the storage tanks regularly; in general every
five years, and more frequently in cold climates.
6. Bleed the tank frequently to drain off any water formed
by condensation.
7. Rotate fuel stocks to prevent deterioration of old fuel
and the accumulation of water or foreign matter.
8. Do not wait for fuel stocks to be used up before get-
ting in new supplies; refuelling from the bottom of the
tank leads to a risk of damage to the fuel system.
Advice on the use of fuel in cold weather
1. Diesel fuel increases in viscosity and wax particles
form in cold weather. This may lead to operating prob-
lems if precautions are not taken.
2. Underground storage is preferable.
IMPORTANT: Protection of the environment - local reg-
ulations in force relating to underground storage must
be complied with.
If this is not possible, place the storage tank or drum in
a location which is protected from the cold, wind or
damp.
3. After filling the storage tank, drain the first 5 litres into
a drum before filling the fuel tank. After refuelling the
tractor, return the fuel in the drum to the storage tank.
4. Insulate all exposed pipework. Ensure that any pipe-
work is short in length and designed to be disassem-
bled if necessary.
5. Stock “winter” quality fuel during the cold weather
season.
Frequently clean the fuel filter sediment bowl.
Do not puncture the fuel filter.
Ensure a spare filter is always available. If a stoppage oc-
curs, due to fuel waxing, in most cases changing the fuel
filter will make restarting possible.
5.23 - STORING THE TRACTOR
If a tractor is not going to be used for a long time, certain
precautions must be taken to protect it. Consult your dealer
or agent for further information.
