IMPORTANT SAFETY INFORMATION
Be Alert for Off-road Hazards
The terrain can present a variety of challenges when you drive off-road. Continually judge
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 TrailMaster Go-kart MID 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 drive safely.
Don't drink and drive
Do not drive your TrailMaster Go-kart MID after drinking. Even one drink can reduce
your ability to respond to changing conditions, and your reaction gets worse with every
additional drink. So don't drink and drive, and don't let your friends drink and drive either.
Do not operate this TrailMaster Go-kart MID at night
Dark vision can greatly reduce a driver's visibility and judgment. So driving at night is
dangerous and can increase the possibility for an accident.
Never run your TrailMaster Go-kart MID indoors
The exhaust from the engine contains a tasteless, odorless and poisonous gas called
carbon monoxide.
Keep away from moving parts of the TrailMaster Go-kart MID
The operator of the TrailMaster Go-kart MID should never place their hands or other parts
of their body near any moving part of the TrailMaster Go-kart MID. 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 in 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 driving carefully.

ARE YOU READY TO DRIVE?
Before each drive, you need to make sure that you and your Go-kart are ready to drive. To help
you be prepared, this section discusses how to evaluate your driving readiness, what items you
should check on your TrailMaster Go-kart MID, and which adjustments would be done for your
comfort, convenience, and safety.
Before you drive this TrailMaster Go-kart MID for this first time, we urge you to:
Read this owner's manual and the labels on your TrailMaster Go-kart MID carefully.
Make sure you understand all the safety messages.
Know how to operate all the controls.
Before each drive, be sure:
You wear your seat belt at all times while driving your TrailMaster Go-kart MID.
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 consume any alcohol or drug.
Protective Apparel
For your safety, we strongly recommend that you always wear a D.O.T. 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
by an accident.
The following suggestions will help you choose the proper protective gear.
Helmets and Eyes Protection
Your helmet is your most important piece of protective 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 D.O.T. (Department of Transportation) sticker on any helmet you buy. Always wear
a face shield or goggles to protect your eyes and help your vision.
Operating this kart without wearing an approved motorcycle helmet, eye protection,
and protective clothing could increase your chances of head and/or eye injury, and the
possibility of death in the event of a severe accident.
Always wear an approved motorcycle helmet that fits properly and wear eye protection
(goggles or face shield), gloves, boots, long-sleeved shirt or jacket and long pants.
WARNING
