performance, value and innovation. It’s not an easy task compromising so
we have done our best not to. We’ve included what we believe to be the
best radio system in its class; the most durable and robust brushless power
plant that includes proprietary technology; high performance engineering
grade composite plastics with aircraft grade aluminum and high carbon
steel components. We’ve taken a chassis platform that could have been
ok and made it great. The components by themselves can be seen as
capable, over engineered, rened and optimized, but their specs weren’t
chosen because of how they perform when their independent, we’ve put
them all together where each component complements each other with
perfect synergy into the product that best ts our customers’ needs and
expectations. It’s not just about being good, it’s about being Select.

Getting Started
Below are some steps to help get you going right away and most applicable
to those who have used RC products before. If you are new to the hobby or
it has been a while since you’ve worked with the latest technology, please
read through the manual to acquaint yourself with the latest procedures,
Warnings, Cautions and Tips.
Charging
Although this information should be included with your batteries and charger,
we have included it here again to ensure you have seen it and are aware
of the most common things to be aware of with regards to charging our
batteries.
• Never leave the battery unattended while charging and never operate the
charger without adult supervision.
• Never charge a warm battery, always allow the battery to cool to room
temperature before charging.
• Never drop the charger or battery and do not attempt to charge a
damaged battery.
• Inspect the battery and charger before use. Never use a battery or
charger if the wire or connector has been damaged or if the battery has
experienced a short.
• Incorrect use of the battery, connections, or charging equipment can
cause personal injury or property damage.
• Never allow batteries or charger to come in contact with moisture at any
time.
• Stop charging immediately if the battery or charger becomes hot or
changes form during use.
WARNING: WHEN USING LIPO BATTERIES, ONLY USE CHARGERS DESIGNED
FOR USE WITH LIPO BATTERIES FOR THE RC INDUSTRY THAT ENABLE BALANCE
CHARGING AND USE THE SUPPLIED CONNECTOR. USE OF OTHER (NON-RC
SPECIFIC) CHARGERS OR CONNECTORS CAN CAUSE CATASTROPHIC FALURES AND
CAUSE PERMANENTLY DAMAGE YOUR BATTERY AND/OR CONNECTED EQUIPMENT.
THIS PRODUCT IS NOT A TOY AND SHOULD NOT BE CHARGED, OPERATED, OR
MAINTAINED WITHOUT SUPERVISION OF AN ADULT.
Fully balance charge your chosen 2S or 3S LiPo battery in accordance with
charging and safety guidelines supplied with the battery. LiPo batteries are
sensitive to the charge current and as such, it should be chosen with care.
• The battery pack must have a compatible HCT plug, never use plug
adapters that include a non-high-current connector.
• You can use a suitable NiMH battery pack, however you must change
the LVC (low voltage cut-off) on the ESC (see Appendix at the back of this
manual for ESC settings)

Radient Reaktor60-4T Brushless System Overview
The Radient Reaktor series brushless motor and ESC is a great power plant
to satisfy your need for speed and performance, not just an entry level
brushless system, your Reaktor system has some of the most advanced
technology in ESC and motor development in the industry today. Here are
some great features we included that help keep your system running in top
shape ensuring maximum enjoyment potential.
CAUTION: ALWAYS ALLOW YOUR MOTOR TO COOL BETWEEN RUNS. EXCESSIVE
ACCELERATION AND AGGRESSIVE DRIVING WILL CAUSE YOUR SYSTEM TO GET
HOT. EXCERCISE GREAT CARE WHEN HANDLING YOUR VEHICLE AFTER RUNNING
TO AVOID GETTING BURNED.
Some Great Features of your ESC
• Total System Protection (TSP) is an exclusive technology which protects
your entire system against typical failures experienced and sometimes
caused by by new users.
CAUTION: ALTHOUGH TSP HAS BEEN ENGINEERED TO PROVIDE THE MAXIMUM
PROTECTION AVAILABLE TODAY, IT IN NO WAY MAKES FAILING PRODUCT
IMPOSSIBLE. TSP PROVIDES ADDED PROTECTION AGAINST THE MOST COMMON
TYPES OF FAILURES EXPERIENCED AND SOMETIMES INDUCED BY NEW USERS.
• Ready for all weather conditions allowing you to experience the fun of
rain, puddles and snow.
CAUTION: REMOVE THE COOLING FAN WHEN RUNNING IN WATER TO PREVENT
FAN OVERLOAD AND FAILURE. AFTER RUNNING, CLEAN AND THEN DRY THE ESC
AND FAN TO AVOID OXIDATION OF THE COPPER CONNECTORS.
• Specially designed for RC car and truck, with excellent start-up,
acceleration and linearity features.
• Compatible with sensorless brushless motors.
• 2 running modes suitable for different applications (“Forward with brake”
mode, “Forward/Backward with brake” mode).
• Proportional ABS brake function with 4 steps of maximum brake force
adjustment, 8 steps of drag-brake force adjustment.
• 4 start modes (“Punch”) from “Soft” to “Very aggressive” to be suitable
for different chassis, tires and tracks.
• Multiple protection features: Low voltage cut-off protection for LiPo or
NiMH battery / Over-heat protection / Throttle signal loss protection /
Motor blocked protection.
• Easily programmed with the “SET” button on the ESC or with the LED
Program Card.
Your ESC has been pre-installed at the factory but before using your
vehicle each time it is good to double check the wiring for damage or loose
connections to ensure everything is in working order before use. Refer to the
diagram below to check the connections of your electronics system. Some
brushless motors such as the Reaktor included with your vehicle use only

10
black wires, this is okay. On sensorless brushless systems the motor will change
operating direction when any two of the motor wires are swapped.
Total System Protection (TSP)
The Reaktor “T” series ESC’s and Motors incorporate the TSP technology. The
TSP system protects against the following failure modes.
• Over-current: Operating your product in very tall grass or in environments
that create a lot of drag in the drivetrain can cause the motor to draw
more current than the ESC is rated to maintain. This incredibly advanced
circuitry is calibrated to sense the current state and predicted state of the
electronics and will shut down the power to the motor to prevent an over-
load condition. The most common causes of an over-current condition are
improper gearing or running in very high drag environments such as tall
grass, wet heavy mud or in situations where damage has occurred to the
drivetrain but gone un-noticed.
• Over-temperature: Exclusive to the Radient Reaktor “T” Series is the
integrated temperature monitoring of both the ESC and the motor. Never
before has a sensorless brushless combo had the technology incorporated
which allows the ESC to monitor the temperature of the motor and enables
the cutting of power to prevent an over-heat melt down of the motor and the
ESC.
CAUTION: RMONITORING THE MOTOR TEMPERATURE AND PROPER FUNCTION
OF THE TSP SYSTEM REQUIRES PROPER CONNECTION OF THE SENSOR PORT
LOCATED IN THE BACK OF THE MOTOR AND THE SENSOR INPUT ON THE ESC.
The Reaktor ESC is Engineered to Communicate With You
LED Status:
• In normal use, if the throttle trigger is in the neutral range, neither the red
LED nor the green LED light up.
• The red LED lights when the car is run forward or backward and it will ash
quickly when the car is braking.

11
• The green LED lights when the throttle trigger is moved to the full throttle
position.
Alert Tones:
• Input voltage abnormal alert tone: The ESC begins to check the input
voltage when power on, if it is out of the normal range, such an alert tone
will be emitted: “beep-beep-, beep-beep-, beep-beep-” (There is 1 second
time interval between every “beep-beep-” tone).
• Throttle signal abnormal alert tone: When the ESC can’t detect the normal
throttle signal, such an alert tone will be emitted: “beep-, beep-, beep-”
(There is 2 seconds time interval between every “beep-” tone).
Protection Functions:
• Low voltage cut-off protection: If the voltage of a LiPo battery pack is lower
than the selected threshold for 2 seconds, the ESC will cut of the output
power. Please note that the ESC cannot be restarted if the voltage of each
LiPo cell is lower than the set threshold.
• Over-heat protection: When the temperature of the ESC is over 105 degrees
Celsius for 5 seconds, the ESC will cut off the output power.
• Throttle signal loss protection: The ESC will cut off the output power if the
throttle signal is lost for 0.2 second.
Throttle Range Calibration
1. Hold your transmitter approximately 1ft away while calibrating the ESC.
2. Turn Transmitter ON rst (transmitter should ALWAYS be ON if the ESC is
ON.
3. Ensure your Throttle channel (Ch. 2) on your transmitter is set to “Reverse”.
4. Adjust both Throttle and Reverse/Brake EPA settings to 100%.
5. With the ESC OFF, press and hold the Set button near the switch and turn
the ESC ON to enter setup mode. Release the button as soon as the LED
begins to ash.
6. Without touching the trigger, press the button to set the neutral position,
the GREEN LED will ash 1 time.
7. Pull/hold full throttle, press the button again, release the trigger, the
GREEN LED will ash 2 times.
8. Push/hold full brake/reverse, press the button again, the GREEN LED will
ash 3 times. Release trigger.
9. Switch the ESC OFF and back ON to complete setup.
10. Check the ESC operation to ensure forward throttle is actually forward, if
not, switch any two of the motor wires and re-check. Then repeat steps 3-8
if you experience odd behavior.

12
Programming your ESC
The Radient Reaktor is a programmable ESC. Although the default settings
should work well for most users, these settings exist so that you can ne tune
the performance of your ESC to your experience and components. Its various
programmable parameters can be adjusted either by interfacing with the
ESC directly (button presses and counting LED ashes), or via the optional
Reaktor Program Box (RDNA0031) which includes a digital readout of the
settings for easier interpretation and faster setup. There are 6 programmable
parameters for your consideration, below are descriptions of each Item and
following is the table and programming instructions for choosing your settings
should you choose to change from the defaults (highlighted in BOLD text).
CAUTION:THE MOST IMPORTANT OF THESE SETTINGS IS THE LOW VOLTAGE
CUT-OFF THRESHOLD (ITEM 3). PLEASE READ THE DESCRIPTION AND USAGE
SCENARIOS BELOW TO BETTER UNDERSTAND HOW TO USE THIS FEATURE.
Item 1: Running Mode:
1. Forward/Brake: This setting is considered as “Race” mode where the
reverse function is disabled.
2. Forward/Reverse-Brake: This setting is useful for normal operation since
it allows for using reverse throttle to back out of a stuck situation.

13
CAUTION: SWITCHING FROM REVERSE TO FORWARD THROTTLE POSITION
QUICKLY WILL CAUSE EXCESS LOAD ON THE ELECTRONICS AND DRIVETRAIN OF
YOUR VEHICLE. IT IS RECOMMENDED TO COME TO A STOP BEFORE CHANGING
REVERSE/FORWARD DIRECTION.
Item 2: Drag Brake Force (Automatic Brake):
1. 0%: This setting allows the vehicle to continue to roll after letting off
throttle without applying automatic-brake
2. 5%: Adding some drag brake will make the vehicle a little easier to
control, especially when driving on a closed circuit type course, helping
you to slow down and make turns easier.
3. 10%: Add more until you nd the right balance of assistance with slowing
down while still being able to maintain good corner speed without
upsetting the vehicle.
4. 15%
5. 20%
6. 25%
7. 30%
8. 40%
Item 3: Low Voltage Cut-Off (LVC) Threshold:
The Reaktor ESC has 6 built in LVC options. It is essential that you use the
proper LVC setting for the type of battery that you are using to achieve the
optimal performance and safest operation from your ESC/Motor/Battery.
This setting should be chosen based on the number and type of cells you are
using. For LiPo batteries we recommend setting the LVC to #5.
WARNING: USING A SETTING LOWER THAN 5 THIS MAY CAUSE OVER DISCHARGE
OF SOME BATTERIES AND CAUSE DAMAGE TO YOUR BATTERY, WHICH COULD
LEAD TO A FIRE.
1. No Protection: ONLY to be used with NiMH or NiCd type batteries. Since
your vehicle comes equipped with an 8 cell NiMH battery, we have set
this mode as the default. The ESC will run as long as possible, draining
all possible energy from the batteries and eventually your vehicle will
cease to function properly.
CAUTION: IF YOU ARE RUNNING YOUR VEHICLE AND NOTICE A SUDDEN DECREASE
IN POWER, YOUR ESC HAS DETECTED BATTERY VOLTAGE THAT IS LOWER THAN
WHAT SHOULD BE SAFELY RUN WITHOUT CAUSING DAMAGE TO YOUR BATTERY
OR ELECTRONIC EQUIPMENT. IF YOU ARE USING NIMH BATTERIES WHILE THIS
HAPPENS AND YOU HAVE ONLY BEEN RUNNING FOR A VERY SHORT TIME, IT IS
VERY LIKELY THAT YOU ARE MISTAKENLY USING ONE OF THE BELOW LVC MODES.
NOTE/TIP: When you notice the operation of your vehicle change, it is time to STOP
running and re-charge your battery.
2. 2.6V/Cell: This setting will cause the ESC to enter LVC protection mode
when the battery voltage is calculated at the selected voltage or less for

14
more than 2 seconds. Since the setting is “per cell” this means that if you
are running a 2 cell battery, the voltage protection will activate relative to
2 x 2.6V = 5.2V. This setting is primarily for use with LiFe type batteries
as the lower end of LVC settings. DO NOT USE THIS SETTING WITH LIPO
BATTERIES.
3. 2.8V/Cell: This setting would be the starting point for using LiFe type
batteries and is not recommended for LiPo batteries.
4. 3.0V/Cell: This setting is only recommended for use with extremely high
quality and highly durable LiPo batteries suitable for competition racing.
Using a setting this low with a LiPo battery may cause excessive “wear
and tear” on your batteries, shortening their lifespan.
5. 3.2V/Cell: This setting is recommended as the default for running
average grade LiPo batteries. If your batteries are relatively old it is
recommended to use setting 6 instead.
6. 3.4V/Cell: This setting can be used with any LiPo battery and will provide
the “safest” discharge level for your batteries however some lower quality
batteries do not sustain their voltage under heavy load and will cause
premature LVC activation. Starting here is a good choice if you are unsure
or just want to be extra cautious.
Item 4: Start Mode/Punch (Higher value is more aggressive):
The Reaktor ESC has 4 “punch” proles that allow you to tune the initial
power output of the ESC to suit your driving, vehicle, and the surface. You will
typically want a lower punch setting when the surface has less traction. To
get the optimal performance out of LiPo batteries, on high traction surfaces,
setting 4 is recommended.
1. Level 1 (70%): This setting will provide the smoothest throttle feel and
least wheel spin.
2. Level 2 (80%)
3. Level 3 (90%): This is the highest setting that should be used with high
performance NiMH batteries such as those included with your vehicle.
4. Level 4 (100%): This setting is recommended for use with LiPo batteries
only and allows you to get the maximum acceleration from your power
system. Choosing a setting higher than #3 for use with NiMH batteries
will cause inconsistent operation of your ESC, including possible
momentary power loss.
Item 5: Maximum Brake Force:
The Reaktor ESC has 4 maximum brake force settings allowing you to tune
your brakes for different driving surfaces. This setting works in conjunction
with the brake EPA setting on your transmitter which can still be used to ne
tune the braking force, however this setting affects the initial brake force
also. Since your vehicle is using a high performance brushless motor which
has great braking efciency already, we have reduced the setting to #3. On
some surfaces you may still nd this setting to be too high and nd that under
heavy braking with 4wd vehicles the rear tires may come off the ground.
This is a very unstable situation and should be avoided at all costs. If this

15
happens, reduce the maximum braking force to a lower setting. If however
you are unable to stop and the lack of deceleration is not due to wheel
slipping, you can increase the braking force.
CAUTION: BE SURE TO CHECK YOUR MAXIMUM BRAKE SETTINGS BY DRIVING
FROM FULL THROTTLE TO FULL HARD BRAKE IN AN OPEN AREA. IF THE REAR
TIRES COME OFF THE GROUND CAUSING A FRONT FLIP, THE VEHICLE WILL
TUMBLE OUT OF CONTROL AND COULD CAUSE PERSONAL OR PROPERTY
DAMAGE.
1. 25%: This is the lowest setting and should only be used when driving with
slow motors and on loose (low traction) surfaces.
2. 50%: It is not recommended to go below this setting on asphalt surfaces
as the stopping power may not be enough to safely slow your vehicle.
3. 75%: This is the default setting we feel will provide you the best starting
point for many different levels of traction on various surfaces. Remember
it is extremely important to only drive a vehicle as fast as you can safely
stop it. If the vehicle hits something or someone it can cause serious
injury.
4. 100%: This setting is only recommended if you are running a slotted
type motor, running this with a slotless style motor combined with a 4wd
vehicle will likely cause front ips thus a loss of control of your vehicle.
Reset to Factory Defaults:
• At any time when the throttle is located in neutral zone (except in the
throttle calibration or programming mode), hold the “SET” key for over 3
seconds, the red LED and green LED will ash at the same time , which
means each programmable item has be reset to its default value.
Audible/Visual Programming Alerts:
In dirty conditions or with various installations scenarios, visibility of the
LED’s may be obstructed. To assist with setting the ESC parameters you will
also be able to hear audible beeps from the motor that will indicate the value
of ashes the LED is transmitting.
To help interpret the beeps and ashes we use a long time ash and long
“Beep---” tone to represent number “5”, so it is easy to identify the higher
quantity of ashes/beeps. This applies to both the programming parameter
selection and also the value of each programmable item.
For example, if the LED ashes as the following:
• “A long time ash” (Motor sounds “B---”) = the No. 5 item
• “A long time ash + a short time ash” (Motor sounds “B---B”) = the No.
6 item
• “A long time ash + 2 short times ash” (Motor sounds “B---BB”) = the
No. 7 item
• “A long time ash + 3 short times ash” (Motor sounds “B---BBB”) = the
No. 8 item
• “A long time ash + 4 short times ash” (Motor sounds “B---BBBB”) =
the No. 9 item.

Adjusting and Tuning Your Vehicle
The Select Four 10SC has been engineered with some available tuning
options listed here for reference. The default conguration has been chosen
to provide what we feel is the most enjoyable experience for most operating
conditions. However we do encourage experimentation and testing as that’s
where the real fun begins!
Ride Height Adjustment
It is ideal to have the drive shafts above level but still allow the shocks to
extend when you lift the vehicle while the vehicle is sitting on a at surface
with the body installed. Use the threaded adjustment collars to achieve the
desired ride height.
• Lowering the collar will raise the ride height of the vehicle and if done
excessively may decrease stability.
• Raising the collar will lower the ride height and may cause the chassis to
drag on the ground.
Upper Shock Position
There are multiple shock installation locations for the top mounting location
of the shock towers. The default positions have been chosen as a good
starting point. Moving the shock mounting location inward will result in a
slightly less responsive feel on the front or rear of the vehicle but it will be a
little more stable. Moving the shock mounting location outward will make the
truck more responsive but less stable in some conditions.
Lower Shock Position
There are multiple shock installation locations for the lower mounting
location of the shocks in the suspension arm. The default location is ideal for
the included shock length. However you can play a little.
• Moving the shocks to the inside location will result in a slightly more
responsive feel on the front or rear of the vehicle but become a little less
stable. This change will also increase the vehicle’s articulation and you
will notice more body roll. Always check and adjust, if necessary, the ride
height of your vehicle after moving the shock mounting locations.
Battery Mounting
Your vehicle comes equipped with foam blocks used to position the battery.
Centered is the default location.
• Moving the battery forward will generally give the vehicle more steering
while exiting a turn, but less while entering a turn.
• Moving the battery backwards will generally give the vehicle a little more
traction but less steering while on power.
• Ensure the foam blocks are in place to keep the battery pack from

changing position in the battery tray.
• It may be necessary to reset the ride height after changing to a heavier/
lighter battery or making a setup change.
General Care
• Always use clean, dry cloth or soft bristle brush to clean your equipment.
• Never use chemical cleansers to avoid damage to the sensitive
electronics and plastics.
Maintenance
We want you to enjoy your product to its fullest potential. For this to happen
it is important to keep your product clean and properly maintained. Lack
of cleaning and maintenance can cause component failure. For best and
continued performance from your product it is recommended to briey
inspect your product for damage every few uses. Typically, a good time to
do this is when changing the battery in your vehicle or while it is charging.
If a problem is discovered, stop use immediately and perform repairs or
seek assistance. Continued use of failed components can cause more
unnecessary damage to your product.
ESC and Servo
The ESC and servo included in your vehicle are rated for all weather use. It
is recommended that you avoid submersion of the vehicle however running
in puddles, rain and snow should not be damaging. If you will be running in
a lot of water it is recommended to un-plug the fan from the ESC to prevent
the fan from being over-loaded from the water. Be sure to re-connect the fan
immediately after use and drying the terminals. Always remove excess water/
snow from your vehicle after running to help prevent corrosion. Using an air
compressor is effective but please use eye protection.
Transmitter
Although the receiver included with your radio system is rated for all weather
use, the transmitter is not. The transmitter should not be used in the rain or
other wet environment to avoid damage to the sensitive electronics.
• Clean dirt and debris off of your transmitter regularly to avoid the
consequences of these getting into the sensitive electronics where they
can cause short circuits and/or restrict motion of the internal steering
and throttle mechanisms.
• Ensure the antenna is kept in proper working order. The transmitter is not
safe to use with a broken or missing antenna.

19
Receiver
Although the receiver included with your radio system is rated for all weather
use, it is recommended that you avoid submersion of the receiver, however
running in puddles, rain, and snow is okay.
CAUTION: ALTHOUGH THE ELECTRONICS ARE PROTECTED FROM THE WEATHER,
THE CONNECTIONS ARE NOT. ELECTRICAL CONNECTIONS WILL CORRODE WHEN
EXPOSED TO MOISTURE WHEN IN USE AND IF LEFT IN A WET CONDITION. IT IS
CRITICAL THAT YOU UNPLUG AND DRY ALL EXPOSED ELECTRICAL CONNECTIONS
AFTER EACH USE IN WET CONDITIONS TO AVOID DAMAGE TO YOUR EQUIPMENT.
• To achieve full operating range with your radio system, it is critical that
the receiver antenna be installed properly and undamaged.
• Inspect any exposed antenna for cuts or abrasions.
• Ensure there are no kinks in the antenna or antenna tube.
• Never fold the end of the antenna over the tube, this will reduce the
range and damage the antenna.
• Ensure the antenna is not being pinched by the set screw that holds the
antenna tube in place.
Gears
Periodically remove the gear cover to clearly inspect the gears and ensure
there is no debris in the gear compartment.
Proper gear mesh setting is crucial for proper operation and life of gears in
your product. It is important to have the pinion gear (attached to motor) as
close to the spur gear (attached to drive shaft) as possible yet while providing
a minimal amount of backlash. Backlash is the rotation one gear has to make
before contacting the other. Having the gear mesh set too tight will cause
excess load on the electrical components and may cause premature failure.
Having gear mesh set too loose will cause excess wear and possible skipping
of teeth during operation thus causing excess wear and premature failure.
Checking the gear mesh and setting proper backlash.
1. Remove the spur gear cover.
2. Check how much movement is allowed (backlash) of the spur gear
before the pinion gear moves (this is mostly feel, not visual). Check this
movement in multiple places by rotating the spur gear approximately 1/6
rotation and rechecking.
3. If the spur gear is allowed to move more than a very small amount, or if it
there is no backlash, the gear mesh must be adjusted. If there is a lot of
movement, it is recommended to attempt to tighten the mesh. Attempted
adjustment should only improve the situation; if the mesh was correct to
begin with, you will know what that feels like, and if it wasn’t correct, it
will be when you are done after following these procedures.

20
Setting the Gear Mesh
1. Loosen the clamping screw securing the motor plate’s rotation in the
motor mount, only enough to allow the motor to rotate in the mount.
Check and ensure there is no debris in the gears affecting the mesh.
2. Rotate the top of the motor away from the center of the chassis, insert
a strip of notebook paper between the pinion and spur gear, then rotate
the motor plate back until there is no backlash. You will have to push/
twist relatively hard to ensure the paper is pressed all the way into the
teeth.
3. Hold the motor snugly in position while retightening the screw. Only
tighten the screw until the motor won’t move. There should be a slight
gap between the coils of the spring.
4. Rotate the spur gear (turn the tires) to feed the paper out of the mesh,
re-check the gear mesh and adjust again if necessary.
5. Re-install the spur gear cover when the mesh is properly set.
WARNING: NEVER OPERATE YOUR VEHICLE WITH THE SPUR GEAR COVER
REMOVED. SEVERE INJURY, DAMAGE TO ELECTRICAL COMPONENTS, AND
EXCESSIVE WEAR AND TEAR ON DRIVETRAIN MAY RESULT.
Shocks
Periodically inspect the shocks for smooth motion, leaking oil and dirt residue
build up around the shaft or caps. Do not allow dirt to build up around the
shock shaft and bottom of the shock. Doing so will reduce the life of the
shock and cause a shock to leak oil. Be sure to clean the shocks regularly
with a clean and dry soft bristle brush and/or rag.
CAUTION: NEVER USE SPRAY CLEANERS TO CLEAN YOUR SHOCKS, DOING SO CAN
CAUSE DAMAGE TO THE SEALS, CAUSING THEM TO LEAK MORE AND REDUCE THE
LIEF AND PERFORMANCE OF YOUR SHOCKS.
Signs to look out for determining if your shock needs to be maintained or
rebuilt.
• Oil around the shaft means the oil leaked from inside and needs to be
replaced.
• Persistent oil around the shock shaft or lower portion of the shock
typically points to damaged O-rings which will need replacing. See your
local hobby dealer for replacement parts.
Relling your shocks:
1. Remove shock from vehicle, remove spring and top cap. Remove the
bleed screw from the cap.
2. With shock shaft extended, add oil to top of body (use only 100% silicone
oil) and reinstall the shock cap. Be sure the o-ring stays “seated” and
does not squeeze out.
