8 MAINTENANCE
The only maintenance required is to change the batteries when required. Also, check the mounting
hardware daily to ensure that there is no damage. Replace any damaged parts before operating the
crane.
8.1 Battery
Replacement
To replace the batteries, remove the 4 screws from the transmitter housing. During battery
replacement, use caution when opening the battery cover and transmitter to avoid damage to the
gasket causing moisture ingress which could corrode the batteries and terminals. Inspect the gasket
surface on the transmitter for nicks or other damages that may prevent the gasket from sealing. If it
appears to be damaged, a replacement gasket should be installed.
Install 4 fresh batteries into the proper location and direction as indicated on the battery holder.
Make sure that the cardboard tube is installed as shown.

After removing the cover visually inspect the gasket for damages.
Insert the new batteries and cardboard sleeves. Ensure the LED starts to flashing, when the batteries
are first install for a wind speed transmitter. LED comes on for 1 second, off 1 sec and back on for 1
sec, then begins to flash. Visually inspect the gasket and tighten the battery cover in place with the 4
cover screws.
