Insufficient AC power systems, poor connections, bad batteries or low electrolyte in
batteries may result in poor charger performance. Refer to Section 2: Electrical System
for electrical requirements, and charger and battery maintenance instructions.
Refer to the Operator’s Manual for detailed charging instructions.
To be able to use the trouble shooting guide safely and effectively, it is important to read
through this guide before beginning any tests.
Do not operate the charger if it is malfunctioning. Personal injury or
property damage may result.
Do not disassemble charger. Return to MEC when service or repair is
required.
To reduce the risk of fire, only use AC circuits and extension cords in
accordance with all National and Local Electrical Codes for the location
of use.
Only use MEC approved lead acid type flooded batteries. Use of GEL
type batteries may damage the charger and cause machine instability
due to decreased weight.
TO REDUCE THE RISK OF ELECTRIC SHOCK, ALWAYS DISCONNECT
BOTH THE POWER SUPPLY CORD AND THE OUTPUT WIRES BEFORE
ATTEMPTING MAINTENANCE.
THE CHARGER SURFACE CAN GET HOT WHILE OPERATING.
CONTACT WITH THE SKIN OR SURROUNDING MATERIALS SHOULD
BE AVOIDED.
TO REDUCE THE RISK OF AN ELECTRIC SHOCK, CONNECT ONLY TO
A PROPERLY GROUNDED SINGLE-PHASE (3 WIRE) OUTLET.
Incorrect assembly may result in a risk of electric shock or fire. The following
procedures are intended only to determine if a malfunction may exist in the charger. As
most returned chargers test good, it is very important that this procedure is followed
and that other problems are corrected before assuming the charger has failed.
The MEC battery charger is a fully automatic type with a maintenance feature that will
maintain battery voltage indefinitely when connected to an AC power source. The
battery charger should be plugged into an un-switched AC power source if the machine
is stored for long periods of time.
IMPORTANT: – All MEC electric aerial lifts are equipped with lead acid type flooded
batteries. The yellow wire loop on the back of the charger must be intact. If it is cut,
broken or damaged the charger may go into GEL charging mode, causing damage to
the machine and/or batteries.
