SOLAR LIGHT TRAILER SCHEDULED MAINTENANCE
SERVICE GUIDE
Battery:
Do monthly check on the battery,tighten the battery cable connections as needed. Wear gloves/eye
protection and use insulated tools.
Clean terminal connections & cables to prevent corrosion. Mix baking soda and distilled water into a paste
and apply with a wire brush. Rinse cleaning residue and dry with a cloth or paper towel.
Keep the top of the batteries clean from dust and debris toavoid creating a current pathway or electrical
leakage across the top of the battery.
Program your voltage set points sothat the battery bank charges at the proper voltage.
Check Battery State of Charge (SoC):
Use a multimeter to keep an eye on how charged your sealed lead-acid batteries are based on the voltage. A
multimeter is equipped with positive and negative probes which allows the meter to get a DC voltage reading
from the battery.
Multimeters give a DCvoltage reading from your batteries.
Look up the battery’s model number tofind its datasheet.It should contain a chart that estimates the battery’s
state of charge based on these voltage readings.
To get the most accurate reading, your batteries should be tested in a resting state. Let your batteries rest for
atleast 2 hours (no charging/discharging) before taking the voltage reading. Attempting to use the multimeter
when batteries are being charged or discharged is going toresult ina higher or lower voltage, depending on
the load.
If your batteries fail to approach 100% SoC even after a full charge cycle, they arelikely defective, damaged,
or have reached the end of their lifespan.
CAUTION:
Under no circumstances should batteries be incinerated, as fire can cause an explosion. Wear approved
gloves when touching electrolyte. Onexposure to skin, flush with water immediately. Ifeye exposure occurs,
flush with water for 15 minutes and consult a physician immediately.

Solar panels:
During the dryseason or extended periods without rain, itisimportant toclean them manually. It is generally
recommended that you perform solar panel cleaning between two and four times per year. All you really need
is a leaf blower or a quick spray with a garden hose, and your panels will be clean and in top condition.
Before you start in with soap and water, you may want to get rid of large debris. You can do this by using a
dry brush to remove twigs, leaves and other larger items. From there, use your scrub brush and soapy water
to gently start scrubbing your solar panels.
You can use your handheld brush to get too easy to reach panels, and a brush with a long or extendable
handle can get to the ones that are higher up. Be sure that you are not too rough when using the brush
because scrubbing too hard may cause micro-scratches to form on the surface of the panels.
Using a hose with a sprayer, rinse offyour solar panels. Do not use a pressure washer because the force of
the spray can damage the panels. Once your solar panelsare clean but wet, use either a window wiper ora
microfiber cloth on a handle to dry the panels.
Making sure there is not residue on your panelsisan important part ofsolar panel maintenance and cleaning.
Residue can create a film that blocks sunlight and reduces energy production in the same way that dirt can. A
window wiper or microfiber cloth can ensure that your panelsareresidue free.
In winter, you may need to clean your panelsafter a heavy snowfall. If you areusing water to clear the snow
away, make sure it is lukewarm. You can also use a squeegee with a long handle. Just remember, never use
hot water when clearing snow offthe panels. The panels aremade of tempered glass, and the extreme
temperature disparity between hot water and cold panels can crack them.
Whenever you clean the solar panels, also check on the solar connectors to make sure all the cables and
connectors are still making good connection.
Air compressor:
1. Periodically check allelectrical and fittings connections. Clean and tighten as needed.
2. Periodically check allmounting screws. Tighten as needed.
3. Replace Air Filter Element periodically. Replacement frequency depends on operating frequency and
operating environment. For frequent usein dusty environment, we recommend that you replace air filter
element atleast once a month.
4. Regularly clean dust and dirt from compressor cooling fins and motor housing.

5. Your aircompressor isequipped with a permanently lubricated, maintenance-free motor. Never try to
lubricate the compressor.
6. All repairs should be performed by Manufacturer orManufacturer’s Authorized Service Agencies only.
CAUTION: Never touchthe air compressor or fittings connected to the air compressor, with bare hands during
or immediately after use. The leader hose and fittings connected to leader hose will become very HOT during
and after use. If necessary, wear heat resistant gloves to handle fittings, airline, and leader hose.
Pneumatic mast:
Masts come from the factory pre-lubricated and require no scheduled maintenance under normal operating
conditions. In extremely harsh environmental conditions, maintenance of the mast might be required. Signs
that cleaning and lubrication are needed can be:
• A noticeable gritty film on the exterior surfaces of the mast sections
• rratic extension or retraction of the mast
•Noisy operation of the mast
• ticking of one or more mast sections when mast isextending or retracting
PROCEDURE:
1. Remove top load from the mast. Thiswill allow the sections ofa non-locking mast to more easily be
extended from smallest to largest. See Step 3. On locking masts, the sequence of extension can be
controlled by the locking collars.
2. When a regulator exists in the pneumatic system, reduce its pressure tobetween 5 and 10 PSIG.
NOTE: 10 PSIG should be sufficient pressure to extend all sections ofthe mast without a top load. Ifany
section will not extend with 10 PSIG the mast may require overhaul. Consult the factory.
3. One person operating the air control valve should slowly pressurize the mast just enough to extend the top
mast section.
Another person may need to hold down the larger mast section collars to assure the proper sequence of
extension. Close the air control valve as soon as the mast section is up.

4. Dampen a rag with a non-abrasive cleanser or solvent such as lacquer thinner to wipe down the extended
mast section. Donot allow the cleaning fluid or solvent torun down inside the collar.
5. Repeat steps 3 and 4 for the nextlarger mast section.
6. Inject approximately 1/2 oz. of Mast Lubricant ora lightweight machine oil into the air holes of the exposed
mast section.
7. Repeat steps 3,4 and 6 for each of the remaining mast sections. The larger diameter sections should be
injected with approximately 1 oz. oflubricant.
8. Lower the mast completely. Allow several minutes for the lubricant tosettle and spread around the wear
ring and seal at the bottom ofeach mast section.
9. Extend the mast againone section at a time in the same sequence (smallest tolargest). Wipe off any
excess lubricant that flows out of the air holes.
Tires:
Check the tires pressure regularly and before transport the solar trailer. Low pressure in tires could cause the
solar trailer tonot level correctly. Fill the tires up with airifthe pressure islow. Replace your tires ifthe tread
worn out.
Trailer’s brake lights &license plate lights:
Check the brake lights, make sure allbrake lights work properly on the trailer before transport. If light does not
turn on, check allwire connections to the light make sure allconnections are good. Iflight still not turn on,
change light bulb.
