IMPORTANT SAFETY INFORMATION
Your Go-Kart will provide you with many years of service and pleasure. Providing
you take responsibility for your own safety and understand the challenges you can meet
while driving.
There is much that you can do to protect yourself when you drive. You’ll find
many helpful recommendations throughout this manual. The following are a few that
we consider most important.
Follow the Age Recommendation
It is strongly recommended that no one under the age of 8 be permitted to drive this
Go-Kart without adult supervision.
Always Wear a Helmet
It’s a proven fact: helmets significantly reduce the number and severity of head
injuries. Always wear an approved motorcycle helmet. We also recommend that you
wear eye protection, sturdy boots, gloves, and other protective gear.
Drive Off-Road Only
Your Go-Kart is designed and manufactured for off-road use only. The tires are not
made for pavement, and the Go-Kart does not have turn signals and other features
required for use on public roads. If you need to cross a paved or public road, get off and
walk your Go-Kart across.
Take Time to Learn & Practice
Even if you have driven other Go-Kart, take time to become familiar with how this
Go-Kart works and handles. Practice in a safe area until you build your skills and get
accustomed to this Go-Kart’s size and weight.
Because many accidents involve inexperienced or untrained drives, we urge all
drivers to take a training course approved by the Go-Kart Safety Institute. Check with
your dealer for more information on training courses.
Be Alert for Off-Road Hazards
The terrain can present a variety of challenges when you drive off-road.
Continually “read” the terrain for unexpected turns, drop-offs, rocks, ruts, and other
hazards. Always keep your speed low enough to allow time to see and react to hazards.
Drive within Your Limits
Pushing limits is another major cause of Go-Kart accidents. Never drive beyond
your personal abilities or faster than conditions warrant. Remember that alcohol, drugs,
fatigue, and inattention can significantly reduce your ability to make good judgments
and driver safely.
Don’t Drink and Drive
Alcohol and driving don’t mix. Even one drink can reduce your ability to respond
to changing conditions, and your reaction time gets worse with every additional drink.
So don’t drink and drive, and don’t let your friends drink and drive either.

IMPORTANT SAFETY INFORMATION
Never run your Go- Kart indoors.
The exhaust from the engine contains a tasteless, odorless and poisonous gas called
carbon monoxide.
Keep away from moving parts of the Go-Kart
The operator of the Go-Kart should never place their hands or other parts of their
body near any moving part of the Go-Kart. Failure to adhere to this warning will cause
physical harm to your body.
Skidding or Sliding
The terrain surface can be a major factor affecting turns, Skidding a turn is more
likely to occur on slippery surfaces such as snow, ice, mud and loose gravel. If you skid
on ice, you may lose all directional control. To avoid skidding on slippery terrain, keep
your speed low and drive carefully.

SAFETY LABELS
This section presents some of the most important information and
recommendations to help you drive your Go-Kart safely, Please take a few moments to
read these pages.
The labels be considered permanent parts of the Go-Kart. If a label comes off or
becomes hard to read, contact your dealer for warning labels replacements.

ARE YOU READY TO DRIVE?
Before each drive, you need to make sure you and your Go-Kart are both ready to
drive. To help get you prepared, this section discusses how to evaluate your driving
readiness, what items you should check on your Go-Kart, and adjustments to make for
your comfort, convenience, or safety.
Before you drive your Go-Kart for the first time, we urge you to:
■ Read this owner’s manual and the labels on your Go-Kart carefully.
■ Make sure you understand all the safety messages.
■ Know how to operate all the controls.
■ Never drive this Go-kart if under 8 years old.
Before each drive, be sure:
■ You feel well and are in good physical and mental condition.
■ You are wearing an approved motorcycle helmet (with chin strap tightened securely),
eye protection, and other protective clothing.
■ You don’t have any alcohol or drugs in your system.
Protective Apparel
For your safety, we strongly recommend that you always wear an approved
motorcycle helmet, eye protection, boots, gloves, long pants, and long-sleeved shirt
or jacket whenever you drive.
Although complete protection is not possible, wearing proper gear can reduce the
chance of injury when you drive.
The following suggestions will help you choose the proper driving gear.
Helmets and Eyes Protection
Your helmet is your most important piece of driving gear because it offers the best
protection against head injuries. A helmet should fit your head comfortably and
securely.
An open-face helmet offers some protection, but a full-face helmet offers more.
Regardless of the style, look for a DOT (Department of Transportation) sticker in any
helmet you buy. Always wear a face shield or goggles to protect your eyes and help
your vision.
Operating this Go-Kart without wearing an approved motorcycle helmet, eye protection,
and protective clothing could increase your chances of head and/or eye injury, possibly
death in the event of severe accident.
Always wear approved motorcycle helmet that fits properly and wear eye protection
(goggles or face shield), gloves, boots, long-sleeved shirt or jacket and long pants.
Additional Driving Gear
In addition to a helmet and eye protection, we also recommend:
■ Sturdy off-road motorcycle boots to help protect your feet, ankles, and lower legs.
■ Off-road motorcycle gloves to help protect your hands.
■ Driving pants with knee and hip pads, a driving jersey with padded elbows, and a
chest/shoulder protector.
