supplied linkage, Quicklink and lock nut, connect the regulator
arm to the servo horn as shown in diagram 3. First pass the
plain end of the rod through the push rod connector on the
regulator arm, and then clip the Quicklink in either the 2nd or
3rd hole on the servo horn. The Quicklink is best fitted by
slightly spreading the two sides with a screwdriver as you
pass it over the servo arm.
Setting and adjustment of the regulator is best done with the
locomotive in steam and with the chassis supported on two
wooden blocks under the chassis to raise the wheels off the
bench. Ensure that the regulator is closed when raising
steam.
With full working pressure raised, switch on both transmitter
and receiver and move the locomotive into gear with the right
hand lever on the transmitter. Open the regulator by slowly
moving the left hand lever upwards and find the position at
which the engine starts to run. Move the arm backwards and
forwards a few times to establish the position at which it
closes and leave it there. If the regulator does not open or
fails to close fully, slacken the grub screw holding the
regulator arm in place, remove the arm and turn the spindle
manually (careful as it's hot!) to find the point at which it just
closes. Move the control lever on the transmitter to the bottom
and replace the regulator arm. Proceed as before to find its
closing position and leave it there. Carefully slacken the grub
screw and move the control lever to the bottom without
moving the spindle. Nip up the grub screw.
You can make fine adjustments to the linkage now until the
regulator closes fully with the control lever at the bottom.
Because of the '0' ring used in the r/c type regulator, you
should aim for the wheels to start moving when you have
moved the control lever on the transmitter about half way up.
