CAUTION: ENVIRONMENTAL HAZARD
DO NOT dispose or allow liquid to seep into the
ground or sewer systems, doing so will cause
environmental damage.
CHANGING THE FUEL FILTER
1. Clean round the fuel filter.
2. Remove the filter with a suitable filter remover.
Collect any spilled fuel in a collection vessel.
3. Clean the filter mating surface on the filter bracket.
4. Lubricate the seal with diesel fuel and install the new
fuel filter. Tighten the fuel filter in accordance with the
instructions on the fuel filter.
STORAGE
PREPARING THE ENGINE FOR A LONG PERIOD
OF INACTIVITY
In the case of a planned period of inactivity that lasts longer
than two months, to prevent the interior parts of the
engine and some components of the injection system from
oxidizing, prepare the engine as follows:
1. Drain the lubricant oil from the sump after heating the
engine.
2. Drain the engine oil and fill up with conservation
oil to just over the MIN marking on the dipstick.
3. Connect the fuel suction and return hoses to a 1/3
full Jerrycan containing conservation oil and 2/3
diesel
fuel.
4. Bleed the fuel system.
5. Start the engine and run at a fast idle until about 2
liters (0.6 US gal) of the fluid in the jerrican have been
used. Stop the engine and re-connect the fuel suction
and return lines.
6. Drain the conservation oil from the engine.
7. Make sure the coolant has adequate antifreeze
properties. Top up as necessary. Alternatively, you can
drain the coolant (also drain the coolant filter).
8. Drain any water and contamination from the fuel
filters and fuel tank. Fill the fuel tank completely, to
avoid
condensation.
REFILLING COOLANT
1. Check that all drain points are closed.
2. Open the caps to both the expansion tank and the
radiator. Fill the expansion tank so that the coolant
reaches the MAX mark on the sight glass. Close the
filler
caps.
3. Bleed the system at the bleeding nipple.
4. Start the engine when the coolant system is completely
filled and vented. Open any bleeding nipples a short
while after starting, to allow trapped air to escape.
5. Start the engine after approx. one hour and check
the coolant level. Top up with coolant as required.
CHANGING AIR FILTER
Do NOT remove filter while engine is running.
1. Unclasp the air filter cover and then remove the filter.
2. Replace the filter. Replace the cover, securing the
clasps.
CLEANING RADIATOR
The surfaces of the radiator come into contact with the
outside air and can be subject to deposits and impurities.
Clean in accordance to the maintenance schedule with
compressed air or steam.
DRAINING WATER IN FUEL FILTER
WARNING: EQUIPMENT DAMAGE
Clean the exhaust valve prior to checking the pre-filter
to reduce the risk for system contamination.
Do NOT perform while the engine is running.
1. Place a container for collecting
liquids under the pre-filter.
2. Unscrew the plug located at the
bottom of the filter.
3. Drain the fluid until only fuel
comes out.
4. Fully hand-tighten the plug.
5. Dispose of liquid in accordance to local codes.
