Use chalk to draw a line 1-2 cm wide along the flange of the V-belt pulley.

Warm up the engine to an oil temperature of 50-70°.

The cold start accelerator button must be depressed.

All electrical consumers are switched off.

Give full throttle and measure the speed with a tachometer.



Use the adjusting screw to set the speed to 4800 rpm.
