●
When the engine is just shut down, the
oil and components are still hot and
can cause burn. Wait until the oil is cool
enough before servicing.
●
Remaining pressure in the tank can
cause oil to squirt out or the screw plug
to fly out. Personal injury could result.
Slowly loosen the screw plug in order
to release the pressure. Never stand in
front of the screw plug.
Always prepare your machine as required
and lock/tag it out before proceeding.
See
“Preparing the machine” on page 2-58 and
“Lock-out and tag-out” on page 2-60.
