EcoSense Emission Monitoring (Optional)
Machines with model numbers ending in “X” are
equipped with the EcoSense Emissions Monitoring
system. EcoSense is an emissions monitoring device
that monitors the exhaust emissions and will shut the
engine down if the emissions levels are too low or too
high.
The monitor must receive a signal from the oxygen
sensor in order to function. If it did not have a minimum
reading requirement it would be possible to disconnect
the oxygen sensor and operate the unit, even if the
emissions were out of limits. In order for the unit to
work as designed it must be able to read both low and
high signals, with “not to exceed limits” of both.
The oxygen sensor must reach operating temperature
before it will start to send signals to the EcoSense
module. This time is set at one minute. A unit may shut
down at a cold start up after one minute because the
oxygen sensor did not reach required temperature to
start to send signals. If this happens, turn the key to
the off position several seconds to clear the EcoSense
module and restart the engine. Once the engine has
started, advance the throttle to full throttle position
and start the operation. With the engine at full throttle
under load, the signal from the oxygen sensor should be
within the normal operating ranges for safe operation.
If the engine’s air intake filter needs to be serviced, or
an over-filled cylinder has been installed by mistake, or
there is a problem with the fuel system that causes the
oxygen sensor’s signal to be out of range, EcoSense
will shut the unit down in four minutes. The unit can be
re-started after clearing the module by turning off the
key switch. If corrections have not been made to the
unit, EcoSense will continue to shut the unit down after
the one minute warm-up and/or four minute out of limit
periods.
Engines tend to go to lean burn if allowed to idle for
even short periods. Even at high idle speeds most
engines will continue to lean downward. It is always
best to shut the engine off when it is not being used
to do work. Remember the engine is always creating
emissions as long as it is running.
The best manner to operate a unit equipped with
EcoSense is as follows.
1. With the throttle in the slow position, turn the key
switch to the start position, once the engine starts,
advance the throttle to full throttle “fast”.
2. When ready to stop operation, release clutch (if
equipped) and move throttle to the slow position. If
the unit will not be used within one minute, turn the
key switch to the off position. If the unit will not be
returned to service within a few minutes it is best
to turn the gas valve on the tank off first and let the
engine consume all fuel that is in lines. Once the
engine dies, turn the key switch to off position.
3. When ready to restart, open the gas valve on the
tank, put the throttle in slow position and turn key
switch to the start position. Once the engine has
started, move throttle to full position and return to
operation.
SAFR
TM
technology monitors the pressure between the
air filter and the carburetor. As the air filter becomes
dirty, this pressure decreases. With SAFR
TM
technology,
this change in pressure results in a reduction in fuel
delivered to the engine. The net result is a Steady Air
Fuel Ratio regardless of the air filter condition.
SafeStop (optional)
SafeStop is a system that monitors the fuel system
and stops engine operation if either an overfilled
cylinder or liquid draw cylinder is used. If SafeStop
is activated, the red LED will illuminate and the
engine will stop operating. If this occurs, remove the
cylinder from the machine, take the cylinder outside,
and verify it is a properly filled vapor draw cylinder.
Note: This system is not a substitute for properly
inspecting propane cylinders prior to bringing inside
a facility. Overfilled or liquid draw cylinders can
damage the fuel system and create a fire hazard.
Refer to the Safety Precautions section in this
manual.
