H. Periodic maintenance

H5.6. Cleanfueltank(31)

Always clean the fuel tank at the start of the winter

season. This avoids problems with condensation in the

fuel tank. Always make sure that the tank is as full as

possible so that condensation is prevented.

--- Empty the tank and rinse it with clean diesel fuel. Screw

in the drain plug again.

--- Fill up with new fuel (if you suspect that fuel is not clean,

use a fine gauze strainer).

IMPORTANT: Never use spirit as anti---freeze agent in the

fuel, as this could cause blockage of the fuel filter and

impair the lubricating properties of the fuel.

H5.7. Change prefilter and fuel fil-

ter (32)

When using over 5 % Biodiesel the changing is every 500

hours.

filter (33)

should always be changed.

dirt enters the inlet pipe.
