RADIO INSTALLATION (Continued)

Step 58. With the radio still turned on, and the throttle control on the transmitter in the neutral position, loosen the set screw
(177) in the linkage adjustment collar (176) on the throttle wire (175) and move the collar (176) until it is 1 /32" away from the
throttle pivot (169). Tighten the set screw (177) in the collar (176). This will be the final location of this collar {176).
Step 59. Check to see that the collar (176) to the front of the brake arm {79) is not touching the brake arm (79). If it is,
loosen the set screw (177) and move the collar forward so that it does not touch the brake arm (79) while the brake arm (79) rests
against the brake drum (82). Loosen the set screw (177) in the collar (176) at the rear of the brake linkage wire (178) and move
the collar (176) until the linkage spring (179) has a slight amount of pre-load on it. Tighten the set screw (177) in this collar (176).
*NOTE: This collar can be adjusted later to change the amount of "panic", or full brake that the truck has.
Step 60. Loosen the set screw (177) in the collar (176) at the front side of the brake arm (79) and move the collar (176) until
it just touches the brake arm (79). Tighten the set screw (177) in the collar (176). This will be the final location of this collar (176).
Step 61. Move the throttle control on the transmitter to full throttle. Refer to the radio manufacturer's instructions and adjust
the end point adjustment so the throttle servo will rotate just far enough to open the carburetor all the way. Now move the throttle
control on the transmitter to full brake. Adjust the end point on the transmitter so that the servo doesn't over rotate when applying
full brake. The servo should only have to move 1/4" in the brake direction.
*NOTE: If your radio system does not have end point adjustments, you may need to move the throttle pivot and brake
linkage wire to
a
different hole in the servo horn. The closer the wires are mounted to center on the horn, the less the wires will
move. If the wires are moved to
a
different hole in the servo horn, start the throttle linkage adjustment again at step
58.

Step 62. Turn the radio switch off (or unplug the exten-
sion wire from the receiver), and then turn the transmitter off.
Make it a habit to always turn the transmitter on first and off
last.
Step 63. Once the throttle and brake linkages are ad-
justed, replace the air filter (154) in the air filter boot (155).
