Use & Care Instructions
·
Brake Adjust – Adjust the red color-coded knob with the white line “up”
for MAXIMUM braking effect. Turn
that
knob counter-clockwise to reduce braking effect. With 1/24 commercial racing
cars on large routed
tracks
only a small portion of the brake range will be used.
·
Sensitivity Adjust - Adjust the silver color-coded knob with the white line “up”
for MINIMUM sensitivity. Turn
that
knob counter-clockwise to increase the sensitivity (provide more power to the
car on initial application of
the
throttle).
·
Caution ! : Regular maintenance is
required to keep the controller contacts clean and
free from foreign
objects
& debris. Failure to properly clean, lube and maintain the contacts will
cause the controller to fail, will
allow
the car to be driven without the throttle being depressed and can result in the
wire wound pot used for
brake
or sensitivity control becoming short circuited & damaged. Please take this
warning seriously and
follow
this process to keep the contacts clean & properly lubricated :
1.
Remove the front half of the controller case by loosening the three bolts
2.
Clean all debris from the nickel-plated contacts with a Q-Tip and lighter fluid
3.
The sliding contacts MUST be CAREFULLY lubricated to reduce contact wear and
provide a
smoother
controller action. To lube, do so as follows :
a.
Place a SMALL amount
of Super Lube PTFE lube on the end of a Q-Tip & apply to the
nickel
contacts in the area where the silver alloy contact travels
b.
Cycle the trigger a few times
c.
Use a Q-Tip with lighter fluid to remove any excess lube outside of the area
where the
contacts
meet (remove 90% of the lube you just applied)
d.
Examine the contact area to insure that cotton fibers from the Q-Tip are
removed and
that
residual lube is minimal & barely visible
4.
Repeat this cleaning / lube process on a frequent basis (every 1-2 weeks) for
best results.
·
Periodic Maintenance – lube the trigger pivot bushing with plastic compatible
oil
Optional Upgrades
·
Power Relay System PMTR2037 – provides a more positive low resistance path at
Wide Open Throttle
·
PMTR2039 5 Ohm Brake Pot if used exclusively for 1/24 commercial racing
