MAINTENANCE
TIPS
BEFORE EACH RUN
1.
IMPORTANT: Check to make sure
that all screws are tight. Always use
threadlock (DTXR2010) on screws
going into metal.
2.
Before running always check the
condition of your radio system batteries and replace/
recharge if necessary.
3.
Check to make sure that all of the moving parts of the
Raze ST move freely and do not bind.
4.
Check the fuel tank and fuel lines for leaks.
5.
Before starting the engine, turn on the radio and make
sure the servos move easily and in the proper direction.
6.
Inspect the air fi lter for a torn or damaged element. Also look
for dirt in the air cleaner element and wash it if necessary.
7.
Check for broken or damaged parts. Replace any broken
or damaged parts before running the Raze ST. Running of
the Raze ST with broken or damaged parts could result in
damage to other parts.
8.
Check to make sure that all wires are properly connected.
AFTER EACH RUN
1.
Clean any large globs of dirt or debris from the chassis
and moving parts.
2.
Drain the fuel tank of any leftover fuel. DO NOT return the
fuel to your fuel jug.
3.
Check for any broken or damaged parts. This way parts
may be replaced before the next run.
4.
Put 2 drops of after-run oil in the carburetor and 2 drops
in the cylinder (removing the glow plug to access the
cylinder) and turn the fl ywheel several times to work the
oil into the engine. This will protect the engine from rusting,
especially when stored for a long period of time.
AFTER EVERY 10 RUNS
1.
Check to make sure that the bearings are free of dirt and
debris, and roll smoothly.
2.
Check the shocks for oil leakage. Inspect the shaft and
O-rings for damage and replace if necessary. (A shock
shaft with scratches you can feel with a fi ngernail should
be replaced.)
3.
Make sure the servo saver is free moving and does not bind.
This will help prevent stripping of the servo during running.
4.
Check for proper gear mesh between the spur and
clutch bell.
TUNING
GUIDE
When tuning the Raze ST make sure that you have equal
lengths from one side to the other on the shocks, camber
rods and steering rods. Also, make sure to have the shock
pre-load adjusters at the same setting from left to right. They
do not have to be the same front to rear.
CAMBER
Camber refers to the angle at which the tire and wheel
ride in relation to the ground when viewed from the front or
rear. Negative camber is when the wheels lean inward and
positive camber is when the wheels lean outward. Usually
adding a small amount of negative camber (0° to -2°) will
increase traction. However, adding too much camber will
decrease traction. The objective is to keep as much of the
tire as possible in contact with the running surface. Never put
in positive camber. Make sure that both sides are equal.
Use the DuraTrax Pit Tech
™
Camber Gauge (DTXR1145) to
accurately set up your Raze ST.
ROLL CENTER ADJUSTMENT
Install the inner upper arm in the lower position for high-traction
surfaces and in the upper position for low-traction surfaces.
