SCREWS TO CHECK IF THEY ARE LOOSE. A COMMON PROBLEM IS
THAT THE REFLECTOR HAS BECOME LOOSE FROM REPEATED
SHIPPING.
The biggest problem that will occur with these units is failure to perform preventative maintenance. After a unit
has been shipped a number of times it is a good idea to check the electrical connections and to look for loose
screws. If loose screws are found and tightened, you will save many problems later.
