Use the same technique to adjust the rear ride height. Again,
refer to the included setup sheet. Every driver likes a little
different feel so you should try small ride height adjustment
to obtain the feel you like. This should be the last adjustments
you make after everything else is dialed in. Note: Do not
use ride height adjustments as a substitute for a spring rate
change. If your 810 needs a softer or firmer spring, change the
spring. Do not think that simply moving the shock nuts will
change the spring stiffness as it will NOT!
Wheels and Tires
The tires come pre-mounted with the vehicle and should
be checked to make certain they stay glued to the wheels.
The wheel spinning speeds this vehicle is capable of tend to
pull the rubber tire away from the rim. When a tire or tires
come loose from the rim, you will notice the vehicle is hard to
control.
Tip the vehicle on its side and using both hands to hold one
wheel at a time, use your thumb to press the tire away from
the rim. If you see a tire pull away from the rim use Losi Tire
Glue (LOSA7880 thick or LOSA7881 thin) to reglue. It only
takes a small drop of glue generally. Be careful—this is CA-
type glue and you do not want to glue your fingers to the
wheel and tire.
Use safety goggles when gluing tires.
Check the mounting of the tire periodically to ensure proper
performance and handling.
Troubleshooting your 810
Many questions are the result of simple user errors or minor
adjustments which are easily addressed. If after reading
below you cannot resolve your problem, then please contact
the appropriate product support office.
Radio system does not work properly:
If the power on your transmitter is not turning on, first check
to make sure the batteries are installed correctly. If the battery
power is too low, replace the four AA dry cells. When you
turn on the vehicle, if the servos fail to move, replace the four
AA dry cells in the vehicle. If the radio still does not function
you may need to rebind the radio. Refer to the step-by-step
instructions elsewhere in this manual to bind your system.
Short radio range:
If the radio range appears short, make sure the batteries are
all fully charged and/or are in good condition.
Steering or Throttle servo does not work:
Check all wires, radio system, battery connectors, and the
battery pack. Replace the servo if it remains unresponsive.
Engine will not start:
1. Remove and check the glow plug.
2. Make sure there is fuel in the tank.
3. Check the fuel line for holes or cuts.
4. Note that the fuel is getting up to the carburetor. If not
wait for the exhaust pipe to cool, put your finger over
the exhaust tip, and turn the engine over watching
for the fuel to go up the fuel line until it gets to the
carburetor. Do not continue to turn the engine over
with your finger over the exhaust tip after the fuel has
reached the carburetor.
5. If the fuel has been left open or is over 6 months old,
try replacing the fuel including that in the fuel line.
