Operation At High Altitudes; Usage Of The Engine - Zipper Mowers ZI-STE2000IV Operation Manual

a) Pull the starting hold (Fig. N) slightly until
you feel the pressure, then release the hold
slowly by hand.
b) When the engine is warming up, turn the
pulling pole of the air-blocking valve to the
"START" position.(Fig. O)

11.2.1 Operation at high altitudes

At high altitudes, the standard carburetor air and
fuel mixture will become excessively dense,
causing the decrease of the engine's functions,
and increase of fuel 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 feets), please ask the
authorized agent 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 1500meters. If these adjustments are not made, the altitude will
have greater influence on power.

Usage of the engine

In order to prevent getting an electric shock because of incorrect operation, the engine
should be earthed. The earth port of the engine and the outside earth source are
connected by a thick cable.
As spare electrical source for buildings, the connection between generator and other electric
power system must be operated by professional electricians. And the operation must comply with
the related laws and electric regulations.
Otherwise, the current of the engine may feed
back to the public circuit. In this case, if the
workers from electric power company or other
people touch the wire when transmitting
electricity, they may be shocked by electricity to
death. On the other hand, when public electricity
power is stored, the engine may burn, explode, or cause fire to the building's electric power
system.
1 – Sign of grounding (Fig. P)
Do not exceed rated power, and the total watt of the connected electrical equipments should
be considered.
Do not exceed the fixed current limit of socket.
Do not link the engine to the household circuit, or else the engine or the household circuit
would be damaged.
Do not modify the engine for other unrealized purposes.

Do not let the starting hold (Fig. N)
rebound, and release it slowly by
hand.
If the engine can not restart after
halting, check the oil level ahead of
other failures.
The nozzle of the engine is
designed for normal altitude areas.
If it is put to use in higher 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 fuel is too low.
If all the installations that are
connected have been earthed, make
sure to earth the engine
