SafeSense Emissions Monitoring System
SafeSense 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 hight.
NOTE: After engine starts, the YELLOW alert light will
flash for a 3 minute warm-up cycle of the SafeSense
system. (The machine may be operated during this
warm-up period.) After the warm-up cycle, the alert
light will go out. None of the SafeSense lights will be
illuminated as long as the machine is running safely.
OIL
: Light comes on when there is low oil pressure. If the
engine losses oil pressure, the engine shuts down
until the condition is corrected. The light comes on
each time the engine is stopped.
TILT/IDLE
: Light comes on when the machine is tilted
to the pad change position and the engine shuts
down. If the machine is allowed to idle for more than
4 minutes, the light flashes for 1 minute then the
engine shuts down.
RED SafeSense SERVICE
: If carbon monoxide
levels exceed a pre-set level, the light will flash.
The machine will shut down after the light flashes
continuously for one minute. If the machine does not
operate normally after the engine air filter is checked
and cleaned, it must be serviced by a qualified
technician.
OXYGEN SENSOR
: If light comes on during normal
operation, check the oxygen sensor wire for a snug fit
into the harness and for a snug fit of the harness into
the SafeSense board. If the light still remains on, the
machine must be serviced by a qualified technician.
TURN GAS OFF
: Light comes on to remind the operator
to turn off the gas after the engine shuts down.
BATTERY
: Light comes on when the battery voltage is
low indicating the need to service charging system.
YELLOW SafeSense ALERT
: If light comes on during
normal operation, check and clean the engine air
filter. Check the carburetor air filter for holes, tears,
or punctures and replace if damaged. If the light
still remains on, the machine must be serviced by a
qualified technician.
NOTE: Any light that is on when the engine stops
will remain illuminated for 20 seconds to indicate the
reason for machine shut down.
The oxygen sensor must reach operating temperature
before it will start to send signals to the SafeSense
module. This warm up period is approximately 3 minutes.
After the initial 3 minutes, the module will start evaluating
the signal from the oxygen sensor and if the module
receives an abnormal reading for a period of 1 minute,
the unit will shut down. If the machine is also allowed to
idle for more than 4 minutes, an indicator light will flash
for 1 minute and then the engine will shut down. If this
happens, turn the key to the “off” position several seconds
to clear the SafeSense module and restart the engine.
Once the engine has started, advance the bail throttle to
operating 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,
SafeSense will shut the unit down after 1 minute. 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, SafeSense will continue to shut the unit down until
the problem is corrected.
Engines tend to go to a 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
SafeSense is as follows.
1. With the bail throttle in the idle position, turn the key
switch to the start position, once the engine starts,
advance the bail throttle to the operating position.
2. When ready to stop operation, release the bail
throttle. If the unit will not be used within forty-five
seconds, 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, and turn key switch to the start position. Once
the engine has started, move bail throttle to the
operating 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.
