High Altitude Operation
Preparation
T
o have your machine run at it’s peak performance; you may have to make adjust
ments depending on the elevation. Elevation plays a key role in how the machine
will operate.
The factory setting of the machine is set for elevations from 0—3,000 feet. Any
time the machine is operated above 3,000 feet there are two areas on the machine
the
may
need adjustment.
The first area is the carburetor jet. The higher the elevation, the less air is provided
to the fuel mixture. This will make the engine run ‘rich’, and, in turn will result in
the loss of power, excessive heat in the exhaust, and carbon buildup in the exhaust
and heat exchanger system. The jet sizes vary per engine and elevation. Consult
HydraMaster to obtain proper jet size.
The second area that may need adjustment is the heat control system. The heat
control system is also optimized to 0-3,000 feet. At higher altitudes the boiling
point of water is lowered. In turn, this can cause the water box to boil and the
high pressure pump to cavitate. The heat control system settings will have to be
adjusted to compensate for the elevation. These settings will vary according to
elevation. Contact HydraMaster to obtain the recommended settings.
