Steering friction adjuster
A friction device provides adjustable resis-
tance to the steering mechanism, and can be
set according to operator preference. An ad-
justing screw or bolt is located on the swivel
bracket.
To increase resistance, turn the adjuster
clockwise.
To decrease resistance, turn the adjuster
counterclockwise.
WARNING
EWM00040
Do not overtighten the friction adjuster. If
there is too much resistance, it could be
difficult to steer, which could result in an
accident.

tion.
