and fall. If the motor cannot be trailered in
the normal running position, use an addi-
tional support device to secure it in the

 

tilt position.

lock lever(s) and lift off the cowling. When in-
stalling the cowling, check to be sure it fits
properly in the rubber seal. Then lock the
cowling again by returning the lever(s) to the
lock position.
