John Deere Products & Services Portable Generator DCA70SSJU4i Manuel D’Utilisation

Prior to each use, the generator should be cleaned and 

inspected for deficiencies. Check for loose, missing or 

damaged nuts, bolts or other fasteners. Also check for 

fuel, oil, and coolant leaks. Use Table 16 as a general 

maintenance guideline 

engine Side (Refer to the Engine 

Instruction Manual).

Every 250 hours: Remove air cleaner element (Figure 57) 

and clean the heavy duty paper element with light spray of 

compressed air. Replace the air cleaner as needed. 

This indicator (Figure 57) is attached to the air cleaner. 

When the air cleaner element is clogged, air intake 

restriction becomes greater and the dust indicator signal 

shows 

Red meaning the element needs changing or 

service. After changing the air element, press the dust 

indicator button to reset the indicator.

If the engine is operating in very 

dusty or dry grass 

conditions, a clogged air cleaner will result. This can lead to 

a loss of power, excessive carbon buildup in the combustion 

chamber and high fuel consumption. Change air cleaner 

more 

frequently if these conditions exist.

The air filter should not be changed until the indicator 

reads 

“Red”. Dispose of old air filter. It may not be 

cleaned or reused..

Add diesel fuel (the grade may vary according to season 

and locations).

After prolonged use, water and other impurities accumulate 

in the bottom of the tank. Occasionally inspect the fuel tank 

for water contamination and drain the contents if required.
During cold weather, the more empty volume inside the 

tank, the easier it is for water to condense. This can be 

reduced by keeping the tank full with diesel fuel.

Drain the fuel inside the fuel tank completely. Using a spray 

washer (Figure 58) wash out any deposits or debris that 

have accumulated inside the fuel tank.
