ENGINE STOP LANYARD CORD & REMOTE
The AT125UT has two emergency-stop engine switches. The primary emergency engine shut off switch is the lanyard cord and
the secondary is the wireless engine shut off key fob.
The wireless engine shut off key fob has a limited range that varies in dierent conditions
DO NOT RELY solely on the key fob as the emergency engine shut off swich, especially
during operator training.
KEY FOB:
The wireless engine shut-off is desired for use by an adult supervising the child operating the ATV. The wireless engine
shut-o will work in the range of 50ft. If outside the range of the remote the remote will not stop the engine.
1. Test the range by turning on the ATV and walk 50 feet away and press the shut-off button on
the wireless remote. The engine should stop running, if the engine continues to run, you
may need to get closer or make sure there are no obstructions between the ATV and you.
2. Before using the wireless engine shut-off switch make sure the batteries in the remote are
new and have a full charge. Low or dead batteries in the wireless remote can prevent the it
from working properly.
3. The wireless engine shut-off key fob should not be used as a full-time engine stop switch by
the operator.
Supervising adults can use the wireless engine shut-off switch to turn the
engine off if the operator is riding recklessly or beyond his or her skill level. Once
corrective instructions have been given, the adult can restart the engine using the
wireless remote switch.

LANYARD CORD:
The lanyard cord is designed for use by an adult supervising the child operating the ATV. When using the engine
stop switch cord, be sure the speed limiter on the handlebar is adjusted and the engine speed limits the ATV to a
walking speed.
1. Install the cap on the end of the engine stop switch cord onto the engine shut-off switch
(Red button).
2. Put your fingers in the loop at the other end of the cord.
3. As your child is riding, walk behind the ATV, closely watching his or her actions as well
as the path ahead.
4. If there is a potential hazard ahead or if your child is not riding correctly, pull fimly on the cord (lanyard) to
stop the engine. Because the ATV will continue to roll for some distance,
allow extra time and distance to pull the cord before a potentially hazardous situation
might be encountered.
The ATV will not start without the cap in place.
NOTICE
1. Lanyard Cap
TIP The lanyard assembly can be attached on the left or right
side of the handle bar.

Avoid Carbon Monoxide Poisoning! All engine exhaust contains carbon monoxide, a
deadly gas. Breathing carbon monoxide can cause headaches, dizziness, drowsiness,
nausea, confusion, and eventually death. Carbon Monoxide is a colorless, odorless
tasteless gas which may be present even if you do not see or smell any engine exhaust.
Deadly levels of carbon monoxide can collect rapidly and you can quickly be overcome
and unable to save yourself. Also, deadly levels of carbon monoxide can linger for hours
or days in enclosed or poorly ventilated areas.
If you experience any symptoms of carbon monoxide poisoning, leave the area
Immediately, get fresh air, and SEEK MEDICAL TREATMENT.
Do not run engine indoors. Even if you try to ventilate engine exhaust with fans or open
windows and doors, carbon monoxide can rapidly reach dangerous levels.
When transporting the ATV in another vehicle, be sure it is kept upright and that the
fuel valve is in the off position. Fuel may leak out of the carburetor or fuel tank cap.
