3. Shocks: Periodically inspect the shocks for smooth/free motion, leaking oil and dirt residue build up
around the shaft
a. 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
b. Signs to look out for determining if your shock needs to be maintained or rebuilt
i. Oil around the shaft means the oil leaked from inside and needs to be replaced
ii. Persistent oil around the shock shaft or lower portion of the shock typically points to dam-
aged O-rings which will need replacing. See your local HobbyTown USA® for replacement
parts
iii. Refilling your shocks:
01). Remove shock from vehicle, remove spring and top cap
02). With shock shaft extended, add oil to top of body (use only 100% silicone oil)
03). Slowly compress the shock shaft 50% of travel using a towel or paper napkin to clean
up overflowed oil
04). Slowly reinstall the shock cap and check for free motion of shock
05). It is normal for the shock to rebound (with the spring removed) after full compression
and release
iv. Replacing the O-rings:
01). Disassemble shock and remove shaft from the body
02). Carefully remove lower cap by prying with a finger nail or similar object
03). Remove the O-rings and replace with genuine replacement parts
04). Re-assemble the shock following the Refilling instructions above
4. Tires and wheels:
a. Inspect the tires to ensure they are properly glued to the wheels. The tires on your vehicle come
pre-glued from the factory; however after running your vehicle it is possible for the glue to come
loose in some areas.
i. To reattach the tire to the wheel, use hobby grade Cyanoacrylate (CA) glue and apply small
amounts (one drop at a time) between the tire and wheel. Allow the glue to fully dry before
operating your vehicle
Caution: Be sure to use extreme care when using hobby-grade CA glue. It is specially formulated to cure
quickly and create a strong bond. It will bond skin and can cause injury if used improperly. Follow manu-
facturer’s warnings and directions when using CA glue. It is always recommended to wear eye protection
when maintaining your vehicle.
ii. When reinstalling tires, use caution when tightening the nuts that secure the wheels to the
vehicle. Ensure they rotate freely but don’t wobble excessively. Over tightening the wheels
will cause excess strain on the electrical and mechanical components of your vehicle. Oper-
ating your vehicle under these conditions will void your warranty
iii. Tire wear: Consequently running your vehicle will cause the tires to eventually wear out. Be
sure to obtain and use genuine replacement parts from your local HobbyTown USA® dealer
5. General wear and tear:
a. Use of your vehicle will cause general wear and tear which is not covered under warranty yet may
necessitate replacement of components. Continued operation of your product with use of worn
components may cause continued damage to other components
b. Be sure to regularly inspect your vehicle and accessories for excess wear and damaged compo-
nents
