OPERATING SAFETY
Before using the solar trailer be sure you read and understand all of the instructions! This equipment
was designed for specific applications; DO NOT modify or use this equipment for any application other than
which it was designed for. Equipment operated improperly or by untrained personnel can be dangerous!
Read the operating instructions and familiarize yourself with the location and proper use of all instruments
and controls. Inexperienced operators should receive instruction from someone familiar with the equipment
before being allowed to operate or set up the solar trailer. The following points should be practiced at all
times:
•The area immediately surrounding the solar trailer should be dry, clean, and free of debris.
•Position and operate the solar trailer on a firm, level surface.
•NEVER operate a unit in need of repair.
•Lower tower when not in use, or if high winds or electrical storms are expected in the area.
•Make certain solar trailer is well grounded and securely fastened to a good earthen ground.
•When the mast is raising, make sure area above trailer is open and clear of overhead wires and
obstructions.
•Keep area beside trailer clear of people while raising and lowering mast!
•Trailer must be leveled and outriggers extended before raising tower. Outriggers must remain ex-
tended while tower is up.
•If for any reason any part of mast hangs up or winch cable develops worn while raising or lowering
tower, STOP immediately and replace it.
•NEVER remove safety pin or pull mast locking pin while tower is up!
•NEVER use tower if insulation on electrical cord is cut or worn through.
•If used in dense crowds, please set up guards 5 meters away from the unit.
•NEVER take power directly from the batteries.
•If not being used for a long time, please turn off the breaker for the batteries.

This unit includes solar modules and batteries which are with high voltage circuits capable of causing
serious injury or death. Only a qualified electrician should troubleshoot or repair electrical problems
occurring in this equipment.
•Before servicing solar trailer, make sure the breakers for solar modules, batteries and load are
turned OFF. Disconnect the solar panels and batteries.
•NEVER allow water to accumulate around the base of the solar trailer. If water is present, DO NOT
service!
•NEVER wash the unit with a power washer or high pressure hose.
•Please wear goggles and insulating gloves, using insulation wrench to replace the batteries.
•NEVER disassemble and repair the mast in uneven place. The mast must be hung and installed
with equipment.
•NEVER replace the tyres and outriggers or adjust and fix the brake system in uneven place.
•NEVER replace the manual (electric/hydraulic cylinder) winch when the mast is extending.
•Make sure slings, chains, hooks, jacks, and other types of lifting devices are attached securely and
have enough weight-bearing capacity to lift or hold the equipment safely. Always remain aware of
the position of other people around you when lifting the equipment.
•NEVER operate electric winch in neutral position when the mast is extending. (Optional electric winch is
selected.)
• During mast extending, once the hole for locking pin aligns, stop operating the manual/electric winch.
• During solar charge process, do not unplug each panels and the connectors for solar input on the trailer.
It will lead to severe personal injury and equipment damage.
•NEVER put conductive metal objects on the batteries.
• Do not forget to insert the safety locking pin when cranking up the outrigger.
SERVICE SAFETY

Towing a trailer requires care! Both the trailer and vehicle must be in good condition and securely fas-
tened to each other to reduce the possibility of an accident. Also, some countries require that trailers
be registered and licensed. Contact your local Department of Transportation office to check on license
requirements for your particular unit.
•Check that the hitch and coupling on the towing vehicle are rated equal to, or greater than, the trailer's
"gross vehicle weight rating" (GVWR).
•Check tires on trailer for tread wear, inflation, and condition.
•Inspect the hitch and coupling for wear or damage. DO NOT tow trailer using defective parts!
•Make sure the trailer hitch and the coupling are compatible. Make sure the coupling is securely
fastened to the vehicle.
•Connect safety chains in a crossing pattern under the tongue and if the trailer is with electric brake,
attach the breakaway cable TO THE REAR BUMPER OF THE TOWING VEHICLE. Do not attach
the cable to the trailer hitch.
•Make sure directional and brake lights on the trailer are connected and working properly.
•Check that all lug nuts holding wheels on are tight and that none are missing.
•Maximum recommended speed for highway towing is 45 m.p.h (72km/h). Recommended off-road
towing speed is not to exceed 10 m.p.h. or less depending on terrain.
When towing, maintain extra space between vehicles and avoid soft shoulders, curbs, and sudden lane
changes. If you have not pulled a trailer before, practice turning, stopping, and backing up in an area
away from heavy traffic.
A film of grease on the coupler will extend coupler life and eliminate squeaking. Wipe the coupler clean
and apply fresh grease each time the trailer is towed.

1. Place the trailer on firm ground that is relatively flat. This will make it easier to level the tower. Apply the hand
brake and block the wheels on the trailer to keep it from moving.
2. Connect a good earthen ground to the grounding stud on the base of mast.
3. Pull the locking pin on the jockey wheel and rotate it 90º until the spring loaded pin snaps back into place.
Turn the jack handle anticlockwise to raise the trailer drawbar off of the towing vehicle.
4. Pull the locking pins on the outriggers and extend each outrigger until the locking pin snaps back into place
(A).Pull out the locking pin in the bottom of the outrigger and fit it to the third hole above (B). Apply the same
action for the other 3 outriggers. Turn the jack handle clockwise to start leveling the trailer. Adjust all four jacks
by turning their handles clockwise until they are firmly in contact with the ground and the trailer is as level as
possible (C). (D is the level meter.)

SOLAR PANELS SLIDING OUT AND ANGLE ADJUSTMENT BY HYDRAULIC SYSTEM

1. Before raising the tower it is be necessary to install the top devices and adjust them to the required condition.
2. Check mast ropes for excessive wear or damage. Make sure the ropes are properly centered in each pulley.
Check the mast electrical cord for damage.
WARNING
The trailer must be leveled with the outriggers extended before raising the tower. The outriggers
must remain extended while the tower is up. Failure to level the trailer or extend the outriggers
will severely reduce the stability of the unit and could allow the tower to tip and fall.
WARNING
Do not operate the unit if the insulation on the electrical cord is cut or worn through.
Bare wires in contact with the mast or frame may energize the trailer and cause
electrocution. Repair or replace cord.
3. Before raising the tower, make sure the steel ropes are orderly and tightened (A). If slack, it will lead to
steel ropes wear and even breakage. Crank up the mast clockwise (B) and extend it to the required height. If it is
extended to the maximum height, please insert the safety locking pin (C). Extend the mast slowly, making sure
that the electrical cord is extending at the top sections of the mast. If, for any reason, the cable begins to develop
slack or any of the tower sections get stuck, STOP IMMEDIATELY and contact an authorized service center.

Bare wires in contact with the mast or frame may energize the trailer and cause
electrocution. Repair or replace cord.
WARNING
When the mast is extended, do not operate
the neutral gear bolt on the electric winch. It
will lead to sudden falling of the mast and
cause equipment damage and personal
injury or death.
Neutral Gear Bolt
4.Before raising the tower, make sure the steel ropes are orderly and tightened (A). If slack, it will lead to steel ropes
wear and even breakage. Then press the extending button on the controller and lift the mast to the required height.
When the mast reaches its maximum height, the limit switch will cut the power off automatically. Please insert the
locking pin (B) If, for any reason, the cable begins to develop slack or any of the tower sections get stuck, STOP
IMMEDIATELY and contact an authorized service center.
CAUTION
Do not extend the mast beyond the colored mark on top of the lower mast section. On solar trailers
equipped with the electric winch option, a limit switch on the main mast section will
disconnect power to prevent over extending the mast.
