Running in a new machine

The way a new moped is run affects its life, performance, and
fuel consumption.
Therefore observe the following instructions during the break
in period.
a) Mix the fuel — regular gas with two cycle oil in 40:1 ratio.
Note: Use two cycle oil only!
b) Use this fuel during the break-in period (for about 400 km-
200 miles) and do not exceed the maximum speed over

(25 km/h for 30 km moped)
(35 km/h for 40 km moped)
(40 km/h for 50 km moped)

with the throttle opened no more than by 1/2 to 3/4 of the twist
grip.
c) When riding down a long hill do not throttle down but decelerate by applying the brakes, and never exceed
the speed.
d) Remember that the engine is cooled less efficiently when riding in the warm season with the wind in your
back.
e) Do not let the engine idle too long and do not race it unnecessarily after stopping the moped.

Braking and stopping

If you have to slow down, release the twist grip and apply the brakes by pulling the brake levers (2.3 -Fig.2).
Proceed in the same way to stop the moped. The reduction of engine speed results in the disengagement of
the driving clutch, and the engine runs at idling speed. To continue the ride, just accelerate (turn the twist
grip). The driving clutch engages and the moped starts moving. At the end of the trip stop the engine by
depressing kill switch push button and shut off the fuel supply by turning the lever of the fuel cock (Fig. 6)

Disengagement of engine drive
To disengage the drive, the engine must be off and the moped at a standstill

.

If you intend to use the moped as a bicycle, (after using up the fuel) pull the driving lug (in the direction
away from the engine) and rotate it 90 degrees clockwise or counter clockwise, and then release it (Fig.9).
The driving lug will remain engaged in this position and the drive is not transmitted from the engine to the
rear wheel.
To re-engage the engine, pull the driving lug, rotate it 90 degrees, and release it. After moving the moped
slightly on its wheels, or after turning the rear wheel, the driving lug retracts automatically in mesh with the
engine.

NOTE: Do not disengage the engine drive when riding downhill. Use the engine disengaging device
when pushing or handling the moped, when testing the engine with the moped stationary, and when
pedalling to complete a trip with a defective engine or when out of fuel. When changing the
disengaging mechanism, engine must be OFF.
