WATER-RESISTANT VEHICLE WITH WATER-RESISTANT ELECTRONICS
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, fingers, 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.
Your new Force RC Hammerjaw™ Rock Bouncer has a special
water-resistant coating on the electronics to ensure reliable
performance in higher than average moisture conditions. This
conformal coating can offer mild protection from water, fuel
and motor spray.
• DO NOT
submerge this product under water for any period of
time. If it is submerged, it may result in damage or loss of function
.
• DO NOT pour water onto or allow excess water to come in
direct contact with the product.
• DO NOT use this product in wet or moist conditions such as
puddles, mud, and heavy wet or dew-covered grass.
• DO NOT operate this product in heavy rain or snow.
In case of excess exposure to water or debris, immediately
remove the component, wipe down the exterior with a soft
cloth, and allow it to fully dry before next use.

COMPONENT SPECIFICATIONS
BINDING
Binding is the process of programming the receiver to recognize
the GUID (Globally Unique Identifier) code of a single specific
transmitter. The FCES1308 transmitter and FCES13002 2-in-1
receiver/ESC are bound at the factory. If you need to rebind,
follow the instructions below.
1. Connect power to the ESC/receiver unit.
2. Turn power on. The red LED will begin to blink slowly.
3. Insert the bind plug into the 2 pin bind port on the ESC/
receiver unit. The red LED will begin to flash quickly.
4. Power up the transmitter. Once the red LED turns solid,
binding is complete, Remove the bind plug from the ESC/
receiver unit.
FAILSAFE
In the unlikely event that the radio link is lost during use, the
receiver will set the throttle to its pre-programmed failsafe
position. If the receiver is turned on prior to turning on the
transmitter, the receiver will enter failsafe mode. When the
transmitter is turned on, normal throttle control is resumed.
To set failsafe, begin with the throttle at neutral, then press and hold
the button on the receiver until the LED begins to flash quickly. When
the LED changes to be steadily lit, the failsafe position is set.
Failsafe must be set every time
the system is bound. Binding will
reset the failsafe setting.
SHOCK CLEANING
Oil-filled shocks will require regular maintenance due to the oil breaking down or getting dirty. This
maintenance should be performed after about every 3 to 5 hours of use, depending on the conditions
that the vehicle is used in.
• Remove the shock from the vehicle.
• Remove the cap from the shock body and dispose of fluid.
• Disassemble the shock. Clean thoroughly with DYN5505. Dry parts before assembly.
• Re-assemble the shock and refill the shock body with silicone fluid (30 weight recommended).
• Slowly move the shaft and piston up and down to remove air bubbles.
• Move the piston to the midway point of the body and install the cap.
• Wipe off any overflowing fluid.
• When properly filled, the piston should rebound about 3/8 in (9.5mm) after being pushed in fully.
• Re-install the shock on the vehicle.
