Manual.

Do not loosen or remove bolts, do not weld, drill, modify,
bend, or straighten a damaged structure.

4.17 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 (69 -87 kPa).

CAUTION
Unless you have the proper training, tools, and
experience, DO NOT attempt to mount a tire on a rim.
Improper mounting can produce an explosion which
may result in serious injury.
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.
NOTICE
A sliding panel located under the frame can be loosened
and pulled back to allow dirt and debris to fall though
frame.
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.
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.
