OT EXTENDED LIFE COOLANT must be used in this machine. Depending on the date of manufacture, the machine
could have either coolant type. Machines with OAT coolant will have a decal near the fill location. Never mix conven-
tional coolant with OAT coolant. See page
7-22 for instructions on switching coolant types.
This mixture is used if the lowest ambient temperature is above -37 °C ( -34.6 °F ). If the ambient temperature is lower,
adjust the mixture to attain a lower freeze point using the freeze point-concentration chart on the label of your an-
tifreeze concentrate. Never use a coolant solution containing more than
60 % glycol. It is recommended that ethylene
glycol and water be used in your machine all year.
Prior operation:
Keep all unauthorized personnel clear of the area. Park the machine on level ground, in neutral with the parking
brake applied, and the attachment lowered to the ground. Make sure that all residual pressure is relieved from circuits
before beginning maintenance.
