low temperatures (wax appearance, which may plug filters).
Number 2-D diesel fuel above 20° F (–7° C) will contribute
toward longer life of the pump components. Do not use furnace
oil. Furnace oils usually contain heavy cracked distillates
which are not suitable for diesel engines.
Store fuel outside of buildings in a convenient location.
Tipping the front of the tank up slightly will allow contaminants
to collect at the lower end away from the outlet. Never empty
the tank below 4 in. (10 cm) from the bottom of the tank to
avoid picking up water and other contaminants that may have
collected at the bottom. Either filter the remainder at the bot-
tom through a chamois or dispose of it periodically to prevent
excessive build-up of contaminants.
Keep all fuel containers free of dirt, water, scale and other cont-
aminants. Many engine difficulties can be traced to contami-
nants in the fuel.
Use only metal containers for fuel storage. DO NOT store fuel
in a galvanized metal container. A chemical reaction will result,
which will plug the filters and cause possible fuel system dam-
age.
Because diesel fuel is flammable, use caution
when storing or handling it. Do not fill the fuel
tank while the engine is running, hot or when
the machine is in an enclosed area. Vapors may
build up and be ignited by a spark or flame
source many feet away. DO NOT SMOKE
while filling the fuel tank to prevent the possi-
bility of an explosion. Always fill the fuel tank
outdoors and wipe up any spilled diesel fuel
before starting the engine. Use a funnel or
spout to prevent spilling diesel fuel and fill the
tank to about 25 mm below the filler neck.
Store diesel fuel in a clean, safety-approved
container and keep the cap in place on the con-
tainer. Keep diesel in a cool, well-ventilated
place; never in an enclosed area such as a hot
storage shed. To assure volatility and to prevent
contamination, do not buy more than a 6-month
supply.
