Norsjö Carrier 4-Stroke
Model Post Petrol Short and Long version
Starting the engine when the engine is warm
A warm engine is started in the same way as a cold engine, with the exception that the
choke is not used.
Stopping the engine
The engine is stopped by turning the ignition switch counter clockwise to position 1.
Make it a habit to always switch off the petrol shutoff valve when driving has been
completed.
Running the engine warm/hot
All parts of the engine expand when they are heated up. They are therefore
manufactured so that they fi t together optimally when the engine has reached its
correct working temperature.
In order to ensure long working life, do not overload or rev up the engine before it has
reached its correct working temperature.
The engine will reach its optimal working temperature when it is run with a light
load 1-3 minutes dependent upon ambient temperature. The engine has reached its
correct working temperature when it responds to the throttle without the choke
having to be used.
DRIVING DURING THE WINTER
Risk of ice forming in the fuel system
When driving during the winter, considerable condensation may build up in the petrol tank.
This is particularly so for vehicles which are exposed to great variations in temperature due to
changes in the weather or if the vehicle is moved in and out of heated premises.
Condensation water can then freeze to ice and produce operating disturbances in the form of
uneven running of the engine; in worst cases the engine will stop completely. Avoid this:
• Keep the petrol tank well-fi lled to avoid condensation.
• Add suitable amounts of carburettor spirits.
Check wires and the chain more often when it is cold.
Both the wires and the chain need extra attention during the winter period. This is particularly
important when driving through areas where road salt has been used. You should therefore make
it a habit to clean the chain and lubricate both the chain and wires more and at more regular
intervals during the winter.
Use the right oil type to make it easier to start when the engine is cold.
Ordinary mineral oil is more viscous when the temperature drops which leads to the engine
being more diffi cult to start during the winter. Half or fully synthetic oils have however
excellent cold-start characteristics and are a more suitable choice of oil for the winter period.
