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 sensors 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.
Hour Meter / Tachometer
The hour meter / tachometer records the number of hours
the machine has been powered ON. The hour meter
reading is used to mark recommended maintenance
intervals. It also displays the engine speed. This meter
displays hours when the machine is turned OFF and
engine speed when the machine is turned ON.
Rok-Bak
1. Close the valve on the propane cylinder, allow the
engine to stop and turn the machine OFF.
2. Remove the propane cylinder.
3. Loosen the handle pivot knobs so that the handle
can slide.
4. Pull the handle out until it stops.
5. Rotate handle towards the front of the machine
until it is vertical.
6. Push downward on the handle until it stops.
