Engine Speed and Maneuvering of Reverse/Reduction Gear
1. Open the throttle so that the engine runs slightly faster than in neutral.
2. Engage the gear in required direction.
3. Set required speed by adjusting the throttle.
Attention!
Engaging the gear for forward or reverse should be done at lowest possible RPM. To
prevent clutch cone damage.
Running-In of engine
Careful use during the first ten hours will increase engine life time. During this time avoid heavy
loads and top RPM.
Full engine power will be reached only after the engine parts have become smoother. This
smoothing process takes place during the first fifty hours or so.
Stopping
1. Move the throttle to idling position.
2. Place the gear lever in neutral position
3. Turn off ignition.
4. Close fuel cock.
5. If exhaust pipe cooling had been installed as shown in Figure 5. C, close the water cock (H).
