Testing the Temperature
The ideal operating temperature for an engine will vary with
the air temperature but in general it should be in the 190° to
230°F (88 to 110° C) range. Since the 810 has a head protector
you will have to rely on your ears or preferably a remote
temperature gauge like the Losi Temp-Tuner™ (LOSA99171)
which incorporates an infrared temp sensor/gauge and
a handy carburetor tuning screwdriver. If the engine is
overheating turn the high-speed needle out (counter
clockwise) at least two hours. If the engine is running rich
(below 190° F) turn the high-speed needle in (clockwise) one
hour at a time until it is running within the normal range.
Driving the 810
Always follow these precautions when running your 810.
The electronics in this model are not waterproof and you
must avoid running it in or through standing water, wet
grass, mud or snow.
Do not run the 810 at dusk or in the dark when visibility is
limited.
Do not attempt to run this model if it will be out of sight
for any amount of time.
Do not run this model near a crowd of people.
Always check for proper radio function and battery
condition before operating.
Check to make sure that the tires are securely glued to the
rims.
Check the model thoroughly for loose nuts, bolts and
screws before and after running.
Make sure you use proper dirt tires if running off-road.
Never run the model with old or discharged batteries –
especially dry cells in the model.
If the model gets stuck do not pull the throttle as it may
result in damage to the engine or clutch.
Leave plenty of room to stop the model. It will take as
much room to stop as it did to accelerate.
Avoid repeated or prolonged heavy braking as this will
cause the brakes to overheat and fail.
Maintenance
In addition to the service needs pointed out in this guide, you
should try to maintain your new 810 for proper performance
and to prevent wear. If dirt gets in the moving parts it
can seriously hinder the performance of the model. Use
compressed air, a soft paintbrush and/or a toothbrush to
remove dirt and dust. Avoid using solvents, if possible, as
this can actually wash the dirt into bearings and areas not
accessible without disassembly, causing additional wear. We
suggest you follow these basic guidelines.
•
Remove as much freestanding dirt and dust as noted
above.
•
Never leave fuel in the tank for more than a couple of
hours.
•
When done running for the day or longer, let the
engine run out of fuel. Remove the air cleaner and
spray a little water-displacing lubricant, or quality after-
run engine oil into the carburetor and spin the engine
over a few seconds.
•
If needed, clean and re-oil the air cleaner before
installing it back on the model.
•
Inspect the chassis for worn, broken or binding parts
and repair as necessary.
