The cooling system is filled with a 50/50 solution of
water and permanent ethylene glycol anti-freeze. Check
the level of coolant at beginning of each day before
starting the engine.
If the engine has been running, pressurized hot coolant
can escape and cause burns.
1. Park the machine on a level surface.
2. Check coolant level. Coolant should be between
the lines on reserve tank, when the engine is cold.
