9.15 WHEEL MOUNTING PROCEDURE ____________________________________________
Remove dirt, grease and oil from the stud threads. Do not lubricate
threads.
Put the wheel on the hub. Inspect the wheel to make sure of full contact between surface of wheel and hub.
Tighten all hardware with your fingers, then torque hardware in the order shown. When possible, tighten nuts in the top
position.
Check and torque hardware each day until torque is kept at 85-95 ft.lb. (115-128Nm).
9.16 RADIATOR _______________________________________________________________
Check coolant level each day. The radiator must be full and the recovery bottle must be at the cold mark.
Drain and fill the cooling system each year. Empty and clean the recovery bottle.
Mix clean water with ethylene glycol anti-freeze for the coldest ambient temperature. Read and follow the instructions
on the anti-freeze container and the Engine manual.
Keep the radiator, engine oil cooler and hydraulic oil cooler air passages clean. Use compressed air (maximum of 30
psi (2 BAR)) to clean the fins. Open the panel under the radiator to allow dirt and other particles to fall from the frame.
Check and tighten the engine fan belt every 100 hours and replace the belt every 500 hours. Replace the clamps and
hoses every two years.
Have your Jacobsen Dealer check the cooling system if you need to add coolant more than one time a month or you
add more than a quart of coolant at a time.
WARNING
Make sure the mower is parked on a solid and level surface. Never
work on a mower that is supported only by the jack. Always use jack
stands.
If only the front or behind the mower is lifted, put the chocks in front
of and behind the wheels that are not lifted.
WARNING
To prevent injury from the hot-engine coolant or steam, never remove the radiator cap with the engine in operation.
Stop the engine and wait until the radiator is cool. When radiator is cool, use caution to remove the radiator cap.
CAUTION
Do not put cold water into a hot radiator. Do not operate the engine without a correct coolant mixture. Install the
radiator cap correctly.
