ACTUATOR
2. Actuator
A: REMOVAL
CAUTION:
•Be careful not to apply excessive load to the
wire cable when adjusting and/or installing;
otherwise, the actuator may be deformed or
damaged.
•Do not bend cable sharply with a radius less
than 100 mm (3.94 in); otherwise, cable may
bend permanently, resulting in poor perfor-
mance.

NOTE:
(A): Must be adjusted when cable end outer is fixed
in place, so that gap between throttle cam and lever
is 0 —1 mm (0 —0.04 in).
(Must be attached while throttle cam is being pulled
by wire cable.)
(B): Must be coated evenly on cam end inner con-
nection.
(C): Cover must be inserted securely, until tip of ca-
ble touches cover stopper.
C: INSPECTION
