Shifting/Riding

You are now in first gear, refered to as the drive or uphill gear.
Depending on the conditions (traffic, road gradient, etc.), you
can shift to a higher gear. Close throttle, at the same time pull
clutch lever and shift to the next higher gear. Let clutch lever
go again and open throttle. If you turned on the choke, make
sure you turn it off again as soon as engine is warm.
When you reach full speed through turning the throttle grip all
the way, turn throttle back to 3/4; the speed hardly decreases
although the engine will use less gas. Never open the throttle
wider than the engine can handle. Excessive turning of the
throttle grip will increase full consumption. 
By shifting down, use the brakes if necessary and close throttle
at the same time. Pull clutch lever and shift down to the next
gear. Let clutch lever go slowely and open throttle or shift
down again.
If the engine is killed f.ex. at a crossing, simply pull the clutch
lever and start. It is not necessary to switch the gear to NEUTRAL.

Braking

Close throttle and apply the hand and foot brakes at the same
time. When driving on sandy, wet or slippery ground use
mainly the rear wheel brake. Always brake with feeling,
blocking wheels can cause you to skid or fall. Also change
down to lower gears depending on your speed.
When driving downhill, use the braking effect of the engine.
Change down one or two gears but do not overspeed the
engine. In this way, you will not need to brake so much and
the brakes will not overheat.
