BEFORE YOU OPERATE
1. Ensure all drain cocks are closed.
Note: The drain cocks are opened
before shipping from the factory.
Marine gear ZF25A does not
have a drain cock on the clutch
cooler.
2. Loosen the filler cap of reservoir to
relieve the pressure, then remove the
filler cap.
WARNING
Burn Hazard.
NEVER remove the coolant filler cap
if the engine is hot. Steam and hot
engine coolant will spray out and
seriously burn you. Allow the engine
to cool down before you attempt to
remove the cap.
