SAFETY PRECAUTIONS AND WARNINGS

As the user of this product, you are solely responsible for operating in a manner
that does not endanger yourself and others or result in damage to the product
or property of others.

This model is controlled by a radio signal subject to interference from many
sources outside your control. This interference can cause momentary loss of
control, so it is advisable to always keep a safe distance in all directions around
your model as this margin will help avoid collisions or injury.

• Never operate your model with low transmitter batteries.

• Always operate your model in open spaces away from full-size vehicles,
traffic and people.

• Never operate the model in the street or in populated areas for any reason.

• Carefully follow the directions and warnings for this and any optional
support equipment (chargers, rechargeable battery packs, etc.) you use.

• Keep all chemicals, small parts and anything electrical out of the reach of children.

• Never lick or place any portion of the model in your mouth as it could cause
serious injury or even death.

• Exercise caution when using tools and sharp instruments.

• Take care during maintenance as some parts may have sharp edges.

• Immediately after using your model, do NOT touch equipment such as the
motor, electronic speed control and battery, because they generate high
temperatures. You may burn yourself seriously touching them.

• Do not put fingers or any objects inside rotating and moving parts, as this
may cause damage or serious injury.

• Always turn on your transmitter before you turn on the receiver in the car.
Always turn off the receiver before turning your transmitter off.

• Keep the wheels of the model off the ground when checking the operation
of the radio equipment.

WATER-RESISTANT VEHICLE WITH WATERPROOF ELECTRONICS

Your new Horizon Hobby vehicle has been designed and built with a
combination of waterproof and water-resistant components to allow you to
operate the product in many “wet conditions,” including puddles, creeks,
wet grass, snow and even rain.

While the entire vehicle is highly water-resistant, it is not completely
waterproof and your vehicle should NOT be treated like a submarine. The
various electronic components used in the vehicle, such as the Electronic
Speed Control (ESC) and servo(s) are waterproof, however, most of the
mechanical components are water-resistant and should not be submerged.

Metal parts, including the bearings, hinge pins, screws and nuts, as well
as the contacts in the electrical cables, will be susceptible to corrosion if
additional maintenance is not performed after running in wet conditions.
To maximize the long-term performance of your vehicle and to keep
the warranty intact, the procedures described in the “Wet Conditions
Maintenance” section below must be performed regularly if you choose to
run in wet conditions. If you are not willing to perform the additional care
and maintenance required, then you should not operate the vehicle in those
conditions.

CAUTION: Failure to exercise caution while using this product

malfunction and/or void the warranty.

General Precautions

• Read through the wet conditions maintenance procedures and make sure
that you have all the tools you will need to properly maintain your vehicle.

• Not all batteries can be used in wet conditions. Consult the battery
manufacturer before use. Do not use Li-Po batteries in wet conditions.

• The included transmitter is not waterproof or water-resistant. If using a
different transmitter than the one included, consult your transmitter's
manual or the manufacturer before operation.

• Never operate your transmitter or vehicle where lightning may be present.

• Do not operate your vehicle where it could come in contact with salt water
(ocean water or water on salt-covered roads), contaminated or polluted
water. Salt water is very conductive and highly corrosive, so use caution.

• Even minimal water contact can reduce the life of your motor if it has
not been certified as water-resistant or waterproof. If the motor becomes
excessively wet, apply very light throttle until the water is mostly removed
from the motor. Running a wet motor at high speeds may rapidly damage
the motor.

• Driving in wet conditions can reduce the life of the motor. The additional
resistance of operating in water causes excess strain. Alter the gear ratio
by using a smaller pinion or larger spur gear. This will increase torque (and
motor life) when running in mud, deeper puddles, or any wet conditions that
will increase the load on the motor for an extended period of time.

Wet Conditions Maintenance

• Remove the battery pack(s) and dry the contacts. If you have an air
compressor or a can of compressed air, blow out any water that may be
inside the recessed connector housing.

• Remove the tires/wheels from the vehicle and gently rinse the mud and dirt
off with a garden hose. Avoid rinsing the bearings and transmission.

NOTICE: Never use a pressure washer to clean your vehicle.

• Use an air compressor or a can of compressed air to dry the vehicle and help
remove any water that may have gotten into small crevices or corners.
