Multiquip LT12P Manuel D’Utilisation

Prior to each use, the light tower should be cleaned and 
inspected for defi ciencies. Check for loose, missing or 
damaged nuts, bolts or other fasteners. Also check for 
fuel or oil leaks.

Check dust indicators on control panel daily or every 10 
hours of operation. If light is ON, clean the air cleaner 
element.

Unlatch the holding clips and take out the air cleaner 

1. 

element.

Clean the inside of the body and cover using a damp 

2. 

cloth.

Blow dry with compressed air (0.69Mpa {7kgf.cm2, 

3. 

99.4 PSI} maximum) against the side of the element 
along the pleats. Then blow dry against outside along 
the pleats, then against inside again.

Remove one seal each time the element is cleaned.

4. 

Replace the outer element (if present, Deutz/

5. 

Lombardini engines has a single element only) after 
cleaning it 6 times or after one year. Replace the outer 
element if indicator is red even after cleaning it.

If seal washer is damaged or the threads of wing nut

are damaged, replace.

Remove evacuator valve and clean it with compressed 

7. 

air. Reinstall.

Add diesel fuel (the grade may vary according to season 
and locations). Always pour through the mesh fi lter.

After prolonged use, water and other impurities accumulate 
in the bottom of the tank. Occasionally remove the drain 
cock and drain the contents. During cold weather, the 
greater the empty volume inside the tank, the easier it is for 
water to condense. This can be reduced by always keeping 
the tank as full as possible.

If air enters the fuel injection system of a diesel engine, 

starting becomes impossible. After running out of fuel, or 
after disassembling the fuel system, bleed the system.

To restart after running out of fuel, squeeze the fuel primer 
bulb to pump fuel into the engine. This unit is equipped with 
an automatic air bleeding system.

If engine is operating in very dusty and dry grass conditions, 
a clogged air cleaner will result in high fuel consumption, 
loss of power and excessive carbon buildup in the 
combustion chamber.

Clean the fuel strainer if it contains dust or water. Remove 
dust or water in the strainer cap and wash it in diesel. 
Securely fasten the fuel strainer cap so that fuel will not 
leak. Check the fuel strainer every 200 hours of operation 
or once a month.

Check the crankcase oil level prior to each use, or when the 
fuel tank is fi lled. Insuffi cient oil may cause severe damage 
to the engine. Make sure the generator is level. The oil 
level must be between the two notches on the dipstick as 
shown in Figure 6.

Stop the engine and allow to cool. Tighten valve of the 

1. 

corrosion resistor (if equipped).

Turn water fi ller cap slowly and remove it.

2. 

Prepare a container to catch the coolant, then open 

3. 

drain plug of the radiator or heat exchanger and drain 
plug of the engine, and drain the coolant.

After draining the coolant, close drain plugs and fi ll 

4. 

with tap water.

Allow engine to cool when fl ushing out 
radiator. Flushing the radiator while hot will 
damage radiator. In addition, the possibility 
of hot coolant exists which can cause 
severe burns.
