Instruction manual
STARTING THE ENGINE 
(a) See that there is sufficient fuel in the petrol tank. 
(b) See that there is sufficient oil in the oil tank. 
(c) See that the gear pedal is in the neutral position. 
(d) Push inward the hexagonal end of off-side petrol tap slide. 
(e) See that the air control lever is in the fully closed position. 
(f) Fully advance the ignition and then slack back the control lever two-fifths of its 
total movement. 
(g) Open the throttle not more than one-sixth of the total movement of the twist grip. 
(h) Depress the plunger on the top of the carburetter float chamber until it can be 
felt the chamber is full of petrol. 
(i) Raise the valve lifter lever and, while keeping it raised, turn over the engine several 
times by depressing the kick-starter pedal, three times, the object being to free 
the engine. (This only applies if the engine is cold.) 
(j) Depress the kick-starter until compression is felt, then raise the valve lifter lever 
and ease the engine just over compression. Then, after allowing the kick-starter 
pedal to return nearly to its normal position, give it a long swinging kick with the 
valve closed and the engine should immediately fire. 
The kick-starter mechanism must be allowed to engage properly before putting heavy 
pressure on the kick-starter crank pedal pin. That means there are two definite 
and separate movements when operating the mechanism by depressing the crank. 
The first is a slow and gentle movement which ends when it is felt the quadrant has 
engaged with the teeth on the ratchet pinion. (See illustration 2.) 
Illustration 3 
Showing the relative 
positions taken up by the 
moving gear indicator 
when the various gears are 
engaged. 
The moving gear indicator 
is attached to the control 
spindle and the fixed gear 
indicator is located on the 
kick-starter case cover. 
The two indicators are 
only in line with each 
other when the foot gear 
change pedal is in the 
neutral position. 
The first slow and gentle movement is essential to avoid damage to the teeth of the 
kick-starter quadrant. 
After the engine has started, slowly open the air lever until it runs evenly. Then set 
the throttle so that the engine is running at a moderate speed (neither racing nor ticking 
over) and allow to warm up. While doing this, check the oil circulation as detailed in 
page 14. The machine can then be taken on the road, 
NOTE—Do not race up the engine from cold and do not flood the carburetter to such 
an extent that petrol is dripping, because then, in the event of a backfire, there 
is a danger of such loose petrol igniting. This cannot possibly happen if the 
starting instructions are carefully followed, but, in the event of a fire, there is 
no cause for panic. Merely turn off the petrol tap to isolate the main supply, 
open wide the throttle and turn over the engine by operating the kick-starter 
pedal when suction will extinguish the fire.
