Be sure to keep the remote control within 10-15 feet of the main drive unit maintain the connection between them.
Check all the bullet points:
Remove the two screws from the case & separate the two halves.
Remove the battery and carefully press the two connectors (circled in blue below) toward each other slightly, to assure they make firm contact when the battery is replaced
note: Connectors can become loosened if the remote is dropped just right - the weight of the battery can bend the connector just enough to cause poor contact.
When replacing battery, make sure the positive (+) end of the battery is facing the bottom of the remote handle.
Once in position, roll the battery in place to ensure good contact with connectors.
Check that the trigger wheel and spring are positioned as shown in illustrations below
when placed in remote handle this side will go down - the other side facing up as shown in the first illustration.
If you have tried all this and are sure the battery is good - please contact [email protected] and describe what is happening and mention everything you've already tried to get it to work. 👍We'll take care you!
