Bodily injury hazard. This
procedure requires specific repair
skills, lifting equipment and a
suitable workshop. Attempting this
procedure without these skills and
tools could result in death or
serious injury and significant
component damage. Dealer
service is strongly recommended.
How to
Remove the Mast Assembly
Perform this procedure on a firm,
level surface.
Perform this procedure with the
mast in the stowed position.
When removing a hose assembly
or fitting, the O-ring on the fitting
and/or hose end must be replaced
and then torqued to specification
during installation.
