DCA-100SSJU — PRE-SETUP
Day-to-day addition of coolant is done from the reserve tank.
When adding coolant to the radiator, DO NOT remove the
radiator cap until the unit has completely cooled. See Table
13 for engine, radiator, and reserve tank coolant capacities.
Make sure the coolant level in the reserve tank is always
between the "H" and the "L" markings.
CAUTION :
When adding coolant or antifreeze to the
radiator, do not remove the radiator cap
until the unit has completely cooled.
Operation in Freezing Weather
When operating in freezing weather, be certain the proper
amount of antifreeze (Table 14) has been added.

When the antifreeze is mixed with
water, the antifreeze mixing ratio must
be less than 50%.

Cleaning the Radiator
The engine may overheat if the radiator fins become
overloaded with dust or debris. Periodically clean the radiator
fins with compressed air. Cleaning inside the machine is
dangerous, so clean only with the engine turned off and the
battery disconnected.
Air Cleaner
Periodic cleaning/replacement is necessary. Inspect it in
accordance with the John Deere Engine Owner's Manual.
Fan Belt Tension
A slack fan belt may contribute to overheating, or to
insufficient charging of the battery. Inspect the fan belt for
damage and wear and adjust it in accordance with the John
Deere Engine Owner's Manual.
The fan belt tension is proper if the fan belt bends 7 to 10
mm (Figure 42) when depressed with the thumb as shown
below.
Never place hands near the belts or fan while
the generator set is running.
Battery
This unit is of negative ground. DO NOT connect in reverse.
Always maintain battery fluid level between the specified
marks. Battery life will be shortened, if the fluid level is not
properly maintained. Add only distilled water when
replenishment is necessary.
The battery is sufficiently charged if the specific gravity of
the battery fluid is 1.28 (at 68°F). If the specific gravity
should fall to 1.245 or lower, it indicates the battery is
discharged and needs to be recharged or replaced.
Check to see whether the battery cables are loose. Poor
contact may result in poor starting or malfunctions. Always
keep the terminals firmly tightened. Coating the terminals
with a thin film of grease will help inhibit corrosion.
