• Immediately after the engine is stopped, the coolant is at a high temperature and the radiator is
under high internal pressure. If the cap is removed to drain the coolant in this condition, there
is a hazard of burns. Wait for the temperature to go down, then turn the cap slowly to release
the pressure before removing it.
• Cleaning is carried out with the engine running. When standing up or leaving the operator‟s
seat, set the lock lever to the LOCK position.
• The engine is operated when washing, so it is dangerous if the machine moves when you are
standing behind it. Never stand behind the machine when the engine is running.
*:Permanent type antifreeze shall meet the requirements of ASTM D3306-03.
Stop the machine on level ground when cleaning or changing the coolant.
The coolant has the important function of preventing corrosion as well as preventing freezing.
Even in the area where freezing is not an issue, the use of antifreeze coolant is essential.
Maeda machine are supplied with Supercoolant (AF-NAC). Supercoolant (AF-NAC) has excellent
anticorrosion, antifreeze and cooling properties and can be used continuously for 2 years or 4000 hours.
Supercoolant (AF-NAC) is strongly recommended whenever available.
To maintain the anticorrosion properties of Supercoolant (AF-NAC), always keep the density of
Supercoolant between 30% and 68%.
When deciding the ratio of antifreeze to water, check the lowest temperature in the past, and decide from
the mixing table given below.
It is actually better to estimate and temperature about 10 degrees C lower when deciding the mixing ratio.
The mixing ration depends on the ambient temperature, but it should always be a minimum of 30% by
volume (antifreeze/total amount of coolant x 100).
The freezing temperature of undiluted antifreeze is -15 degrees C. Do not store undiluted antifreeze at a
temperature of below -15 degrees C.
