Shock Filling Instructions
For both front and rear shocks
Step 1. Start by drilling out the emulsion hole. Use a 1/16th (or 1.6mm) drill bit to drill all the way through and
clear any flashing created by this. Insert the four larger o-rings into the emulsion caps and set aside.
Install the small o-rings onto the small emulsion screws by placing the o-rings on a pit mat or towel and
pressing the screws into the o-rings (add 1 small drop of oil onto the seal to help make the screw slide in easier).
Step 2. Fill shock with oil all the way to the top and pump the shock shaft up and down 3-5 times.
Step 3. Screw on the cap all the way tight (shock tool TKR1115 is helpful for holding the shock body).
Be careful to not cross-thread the caps. Start by turning in the oposite direction before tightening.
Step 4. With the shock at about a 45° angle, push and hold the shock shaft to the top of the stroke and
insert the prepared emulsion screw/seal. Oil should leak out during this process. If it does not, add more oil.
Tighten the screw until snug (do not over-tighten). Wipe o excess oil before moving on to step 5.
Step 5. Pump the shock shaft up and down about 20 times vigorously. This emulsifies the oil.
Step 6. With the shock shaft fully extended, remove the emulsion screw from the cap to do the final bleed.
Step 7. With the shock at about a 45° angle, push and hold the shock shaft to the top and insert the
prepared emulsion screw/seal again. Oil will leak out during this process. Finish by tightening the screw
until snug (do not over-tighten).
We've found it's easiest to complete steps 1 & 2 on each shock before moving on to step 3.
By the time you've finished step 2 on the last shock, the first one will be ready for step 3.

Note: We recommend using a full
size servo with at least 200 oz/in
torque and metal gears. Running less than
our recommended rating will increase
the chance of premature servo failure.
IMPORTANT RADIO SETUP TIPS, MUST READ:
The Tekno RC ET410 is highly tunable, but can be very
aggressive depending on track conditions and tires used.
To help with this, we recommend that you are well informed
about setting up your Steering EPA, Servo Speed, Dual Rate,
and Exponential Curves.
