PRECAUTIONS, SAFETY, AND
MAINTENANCE
The following are K&K Systems’ recommendations for safe and responsible use.
Please remember that the best assurance against accidents is a careful and responsible operator.
PRECAUTIONS
Inspect your unit upon delivery. Wires and plugs may have loosened during
shipment which will cause operational issues. Even though the system arrives
ready to run, inspect all components and test before installation. Test the unit
before installation for convenient working conditions.
• Periodically inspect the trailer and/or unit. This includes but not limited to wheels,
tongue, pins, safety chains, taillights, nuts, bolts, cable clamps, etc. Tighten, repair,
or replace when and where necessary.
• O-load trac cones and barricades prior to message sign deployment.
• The trailer should always be properly setup and leveled with the jack stands
before the message sign is raised.
• Always use safety chains and properly sized hitch ball when towing the unit.
• Always tow trailer units in the down position.
BATTERIES
The batteries are sealed. Check all terminals for proper connection, tightness,
and corrosion. Check the battery condition and charge when necessary or after
storage. It is recommended that the batteries be charged every 3 to 6 months,
regardless of weather conditions. Use an apron, gloves, and safety glasses when
working on batteries. When the batteries have come to the end of their life cycle,
please dispose of them in accordance with your local laws and regulations.
BATTERY CHARGER SAFETY
The battery charger is preset in automatic position. DO NOT CHANGE THESE
SETTINGS because of possible overcharging of batteries. Plug cord into a standard
120 volt AC for charging.
SOLAR PANELS
During operation, keep the solar panel clean of excessive dirt and debris by using
only soapy water and a soft cloth or sponge. Periodically check the integrity of the
wiring connections in the junction box. Inspect for signs of damage to the solar
panel’s glass or frame.
MAINTENANCE
• K&K recommends that the user clean the solar panels every 6 months. Over time
the solar panels may build up a thin layer of dust/dirt/road grime that can
adversely aect their eciency signicantly.
• Check the battery every 6 months to ensure proper charging. If below 12.3 volts,
charge to keep power reserves high. Check solar system by cleaning the panel
and inspecting wiring for wear and secure connection.
• Check that the mounting is secure and has not shifted as the solar panel may shift
direction over time. Ensure the panel is facing South.
• Check the system a few days after installation to ensure proper charging and
operation.
