Usage Features

The manual emphasizes safe operation and provides guidance on various aspects of using the TRACTOR:

Starting the Engine: Instructions are provided for both cold and warm engine starts, including the importance of applying the rear brake, setting the main switch to "ON," and shifting to neutral or park. It notes that the starter motor cranks the engine when the start switch is pushed.
Warming Up: To maximize engine life, the engine should be warmed up before operation, either by operating at one-third throttle for approximately 3 km or idling at 2000 rpm for 3 minutes.
Drive Select Lever: The drive select lever allows shifting between low, high, neutral, reverse, and park positions. It is crucial to stop the TRACTOR and return the throttle lever to the closed position before shifting to prevent transmission damage.
On-Command Four-Wheel Drive and Differential Gear Lock: The TRACTOR offers 2WD, 4WD, and 4WD-LOCK modes. 2WD supplies power to the rear wheels only, 4WD to both front and rear, and 4WD-LOCK ensures all wheels turn at the same speed for maximum traction. Operators are warned to stop the vehicle before changing drive modes to avoid unexpected handling.
Throttle Lever: Controls engine speed. It is spring-loaded to return to idle when released.
Speed Limiter: An adjustable screw limits maximum engine power and speed, useful for less experienced riders.
Brakes: Front and rear brake levers are provided. The front brake lever is on the right handlebar, and the rear brake lever and pedal are on the left handlebar and right side, respectively. Proper brake operation and fluid levels are critical for safety.
Fuel Tank Cap: Removed by turning counterclockwise.
Seat: Removed by pulling the seat lock lever upward and lifting the rear of the seat.
Carriers: Front and rear carriers are available for cargo, with specified maximum load limits.
Shock Absorber Adjustment: Spring preload can be adjusted to suit rider and passenger weight.
Auxiliary DC Jack: Located on the front right side, it provides 12V, 120W (10A) power for accessories like work lights or radios, and should only be used when the engine is running.
Hitch Coupling Device: The TRACTOR is equipped with a hitch for towing trailers, with specified maximum towing and tongue weights.
Riding Techniques: Detailed instructions are provided for various riding conditions, including turning, climbing and descending hills, crossing slopes, riding over rough terrain, and handling skids. Emphasis is placed on proper weight distribution, gradual throttle application, and avoiding excessive speeds.
