e). When the engine is warming up, turn the pulling pole of the air-blocking valve to the
"start" position.
Attention
If the engine can not restart after halting, check the oil level ahead of other failures.
Operation at high altitudes
At high altitudes, the standard carburetor air or gas mixture will become excessively dense,
causing the decrease of the engine's functions, and increase of gas consumption. To enhance
the performance of the engine in high-altitude areas, you can make special adjustments to
carburetor. If you use the engine at an altitude of over 1500meters (5000 feet), please ask
the authorized agent of AKSA to modify the carburetor.
Even though you use the proper nozzle, the horsepower of the engine will still decline 3.5%
as the altitude increases every 300merters (1000 feet). If these adjustments are not made,
the altitude will have greater influence on power.
Attention
The nozzle of the engine is designed for high-altitude areas. If it is put to
use in low altitudes, the outputting power may decline and become too hot, and
even the engine will be damaged seriously because the ratio of the air and
burning gas is too low.
