1/10 4WD SCALER
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), servo(s)
and receiver 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
and complying with the following precautions could result in
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. Caution should be taken
when using Li-Po batteries in wet conditions.
• Most transmitters are not water-resistant. 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
• Drain any water that has collected in the tires by spinning
them at high speed. With the body removed, place the vehicle
upside down and pull full throttle for a few short bursts until
the water has been removed.
CAUTION: Always keep hands, fi ngers, tools and any loose or
hanging objects away from rotating parts when performing the
above drying technique.
• 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.
• Spray the bearings, drive train, fasteners and other metal parts
with a water-displacing light oil or lubricant. Do not spray the
motor.
• Let the vehicle air dry before you store it. Water (and oil) may
continue to drip for a few hours.
• Increase the frequency of disassembly, inspection and
lubrication of the following:
• Front and rear axle hub assembly bearings.
• All transmission cases, gears and differentials.
• Motor—clean with an aerosol motor cleaner and re-oil the
bushings with lightweight motor oil.
