MAINTENANCE AND LUBRICATION
Carburetor/Engine Idle RPM Adjustment
The idle speed adjustment should be performed as outlined in the
Periodic Maintenance Chart, or whenever the idle speed is changed.
Recommended engine idle RPM for the RANGER 2X4 and 4X4 is
1200 +/- 200. Recommended engine idle RPM for the RANGER TM is
1000 +/- 100.
If the engine idle speed is not satisfactory,
and all other conditions are favorable, the
carburetor can be adjusted with the
following procedure.
1. Engage the parking brake and place
the gear shift lever in the neutral
position.
2. Warm up the engine by running the
vehicle approximately five minutes.
3. Remove the the seat and locate the
idle adjust screw (1).
4. Place the transmission in gear (with
park brake engaged).
5. Turn the carburetor idle adjust screw
in or out until the desired idle RPM is
reached. Turn the screw in (clockwise)
to raise RPM. Turn the screw out
(counterclockwise) to lower RPM.
