BB Trainer Revision 3.doc
40
Note the orientation of the servo in the “L” shaped
bracket under the servo. Remove the faulty servo.
Remove screw that secures the servo arm to the
faulty servo. Set the screw, servo arm and the
mounting bracket from the top of the faulty servo
aside for mounting the new servo.
Install the mounting bracket and servo arm on the
new servo. The servo arm should be aligned so that
the Arm will be on the right side of the brass lever
pin, (looking past the receiver to the lever pin), but
not past the either edge of the servo. Observe the
orientation of the lever arm on another launcher
assembly for comparison.
Re-install the servo mounting screws. Use caution
not to over tighten the screws.
Plug new servo into wiring harness. Put new heat
shrink tubing on wiring harness, match wiring
harness colors, and press connector together.
Test servo by turning the receiver toggle switch to
PROGRAM. This sets the servo. If servo does not
activate, reverse the connector. It should move back
and forth slightly but remain in the position described
above. If it does not, remove the servo arm screw,
re-orient the servo arm, and replace the servo arm
screw. Now turn the receiver toggle switch to OFF, then
back to PROGRAM. The servo arm should flicker and
remain in the position. If it does not, call Bumper
Boy Customer Service at 1-800-729-3822.
Apply hot glue on plug, cover with the heat shrink
tubing, and shrink with a hot air gun, blow dryer, or
lighter. Re-install wire ties to secure the wiring
harness.
