Always wear eye protection
when using compressed
air or spray cleaners and
lubricants.
High performance vehicles
generate small vibrations
while driving. These
vibrations may loosen
hardware over time and
require attention. Always
check your wheel nuts and
other hardware and tighten
or replace when necessary.

MAINTAINING YOUR MODEL
Your model requires timely maintenance in order to stay in top running
condition.
The following procedures should be taken very seriously.
Frequently inspect the vehicle for obvious damage or wear. Look for:
1. Cracked, bent, or damaged parts
2. Check the wheels and steering for binding.
3. Check the operation of the shock absorbers.
4. Check the wiring for any frayed wires or loose connections.
5. Check the mounting of the receiver and servo(s) and speed control.
6. Check the tightness of the wheel nuts with a wrench.
7. Check the operation of the radio system, especially the condition
of the batteries.
8. Check for any loose screws in the chassis structure or suspension.
9. Check the operation of the steering servo and ensure that it is not binding.
10. Inspect the gears for wear, broken teeth, or debris lodged between
the teeth.
11. Check the tightness of the slipper clutch.
Other periodic maintenance:
• Chassis: Keep the chassis clean of accumulated dirt and grime. Periodically
inspect the chassis for damage.
• Suspension: Periodically inspect the model for signs of damage such as bent or
dirty suspension pins, bent turnbuckles, loose screws, and any signs of stress or
bending. Replace components as needed.
• Steering: Over time, you may notice increased looseness in the steering system.
The tie rod ends may wear out from use (Traxxas Parts #2742 and #5525).
Replace these components as needed to restore factory tolerances.
• Shocks: Keep the oil level in the shocks full. Use only 100% pure silicone shock
oil to prolong the life of the seals. If you are experiencing leakage around the
top of the shock, inspect the bladder in the top cap for signs of damage or
distortion from overtightening. If the bottom of the shock is leaking, then it is
time for a rebuild. The Traxxas rebuild kit for two shocks is part #2362.
• Driveline: Inspect the driveline for signs of wear such as worn drive yokes, dirty
axle half shafts, and any unusual noise or binding. If a U-joint pops apart, then
it is time to replace the part. Remove the gear cover. Inspect the spur gear
for wear and check the tightness of the set screws in the pinion gears.
Tighten, clean, or replace components as needed.
Storage
When you are through running the model for the day,
blow it off with compressed air or use a soft bristled
paint brush to dust off the vehicle.
Always disconnect and remove the battery from the model whenever the model
is stored. If the model will be stored for a long time, also remove the batteries
from the transmitter.
Suspension assembly removal
The your model was designed with ease of disassembly in mind. The entire front
and rear suspension assemblies can be removed from the chassis fully intact
with the removal of only a few screws. Refer to the exploded views included in
the your model's Service & Support Guide for complete assembly diagrams.
• Removing the front suspension module
1. Remove the two 4x12mm button-head cap screws from the front of the
chassis.
2. Remove the two 4x10mm countersunk cap screws from the top of the
chassis.
3. Remove the 3x15 button-head cap screw from the steering link under the
chassis.
4. Pull the front suspension assembly away from the chassis.
• Removing the rear suspension module
1. Remove the two 4x12mm button-head cap screws from the top of the
chassis.
2. Remove the two 4x12mm button-head cap screws from the bottom of the
chassis.
3. Pull the rear suspension assembly away from the chassis.
4. The center drive can now be removed.
