7.15 RADIATOR _______________________________________________________________
Check coolant level daily. Radiator should be full and
recovery bottle should be up to the
cold
mark.
Drain and refill annually. Remove the radiator cap, open the
engine block drain, and the radiator drain. Empty and clean
the recovery bottle.
Mix clean water with ethylene glycol based anti-freeze for
the coldest ambient temperature. Read and follow the
instructions on the anti-freeze container and engine manual.
Keep radiator and hydraulic oil cooler air passages clean.
Use compressed air (30 psi maximum) to clean the fins.
1. Use a blow gun to clean the radiator and oil cooler fins.
2. Check and tighten the fan belt. Replace clamps and
hoses every two years.
3. If you have to add coolant more than once a month, or
add more than one quart at a time, have a Jacobsen
Dealer check the cooling system.
7.16 ROLL OVER PROTECTIVE STRUCTURE (ROPS)________________________________
A Roll Over Protective Structure (ROPS), designed for this
mower, is available as an optional accessory. If your mower
is equipped with this device, inspect it periodically and follow
operating procedures described in this manual.
1. The seat, the seat belt, mounting hardware, and any
accessories within the ROPS, should be inspected
regularly and all damaged parts replaced immediately.
2. Once the ROPS has been subjected to any form of
impact it should be replaced.
3. Check and torque all hardware. All replacement
components used for the ROPS must be as specified
in the Parts Catalog.
7.17 TIRES ___________________________________________________________________
1. Keep tires properly inflated to prolong tire life. Check
inflation pressure while the tires are cool. Inspect tread
wear.
2. Check pressure every 50 hours or once a month. Use
an accurate, low pressure tire gauge.
3. Keep tires inflated to 10-12 psi (0.69 -0.87 BAR).

wait until it is cool. Even then, use extreme care when
removing the cap.
