Engine —————
Please refer to the enclosed engine manual provided by JOHN DEERE when ordering parts or if you have
questions about the engine.
Always use clean fuel and keep the tank full to minimize water condensation. The engine fuel filter and
water separator canisters are located on the left side of the engine and must be serviced periodically, (see engine
manual). Water should be drained from the water separator, (periodically) and the fuel filter should be replaced
when needed. Initial fuel filter replacement should be at 50-100 hrs and then John Deere recommends fuel filter
replacement every 600 hours of operation, or at the beginning of each season. (Whenever an in-line fuel filter is
used, it is located between the tank and the engine, and should be replaced after the first 50 hrs of operation of a
new machine. After that, the service interval should be at the beginning of each season.) See Specifications and
Fluids page at the back of this manual for diesel fuel recommendations.
Always stop the engine before re-fueling and be careful not to overfill the tank. Do not smoke
when re-fueling, or servicing the fuel system due to potential fire hazard.
It is recommended to change the engine oil and filter at 100-150 hour intervals. See Specifications and
Fluids page at the back of this manual for engine oil recommendations.
Radiator —————
When adding or changing coolant / antifreeze in the radiator, refer to the engine manual provided by
JOHN DEERE to determine proper mixing ratios and quantities to protect against freezing and overheating. See
Specifications and Fluids page at the back of this manual for engine coolant recommendation.
Explosive release of fluids from the cooling system may cause serious burns. Shut off the
engine, and remove the filler cap only when cool enough to remove with bare hands. Slowly
loosen cap to relieve pressure before removing completely.
Check the condition of the fan drive pulleys and belt frequently to see if they are getting
worn and in need of replacement.
To clean the radiator, open the engine compartment hood. Using compressed air, blow thoroughly between
the fins and tubes to remove debris. Do not allow the air nozzle to contact the cooling fins on radiator or condenser.
This will damage the fins and restrict air flow. Blow off the grille. It is the operators’ responsibility to keep the
radiator clean! Failure to do so may cause overheating and void the engine warranty.
This sweeper is equipped with a coolant overflow tank to capture coolant in the event of overheating.
Always maintain the coolant level at approximately 1/3 capacity of recovery tank.
The engine is equipped with a reversible fan to help keep the radiator clean during operation. A
programmed electronic timer reverses the blades approximately every 8-10 minutes to blow trash from the radiator
core. If the operator observes the engine temperature rising beyond normal range, this may indicate excessive trash
in the radiator. An “override button” located on the control console allows the fan to be reversed as needed, in
between “program cycles” providing additional radiator cleaning.
For information about service, adjustments, etc. pertaining to the fan system, refer to the literature provided
by Cleanfix in this manual.
