SAFETY INFORMATION & RULES
Engine Emissions
►Excessive engine exhaust from this machine contains chemicals that may cause cancer,
birth defects, or other reproductive harm. Always operate in a well-ventilated area.
►Look for relevant Emissions Durability Period and Air Index information on the Engine
emissions label, or refer to the engine Owner Manual for additional details.
WARNING
Gasoline is highly ammable and must be handled with care. Never ll the tank
when the engine is hot. Do not allow open ame, smoking, or explosives in the area.
Avoid over-lling and wipe up any spills.
► To prevent a vapor-lock condition, only ll the fuel tank to
approximately 80% of capacity.
►FUEL: The SPIDERSCREED™ uses unleaded gasoline
that must contain no more than 10% ETHANOL (E10) or 5%
METHANOL by volume. In addition, METHANOL must contain
cosolvents and corrosion inhibitors. Use of fuels with a higher
concentration of ETHANOL or METHANOL may result in
starting and performance problems. It may also damage metal,
rubber, and plastic parts of the fuel system and will void the
manufacturer warranty. REFER TO THE HONDA OWNER
MANUAL FOR DETAILS.
Gasoline Engine Precautions
►Whenever possible, remove the machine from the trailer and refuel it on the ground. If this
is not possible, refuel with a portable container—rather than from a gasoline dispenser
nozzle—to minimize the risk of static electricity sparks and/or spillage due to overlling.
►Use only approved gasoline containers.
►Do not use a gas pump nozzle lock-open device.
►Never remove the gas cap or add fuel with the engine running.
►Do not smoke while operating or fueling the machine. Be aware at all times of other
sources of ignition that may be present in the area of the machine.
► Never store the machine or fuel container where there is an open ame, spark, or pilot light
(such as near a water heater or other appliance).
►If fuel spills, don’t start the engine until the fuel is cleaned up and the vapors dissipate.
► Do not remove the fuel lter when the engine is hot, because spilled gasoline may ignite.
Do not spread fuel line clamps further than necessary. Ensure the clamps grip the hoses
rmly over the lter anges after installation.

Located on the right-rear of the SPIDERSCREED™
hood is the 7-inch MD4 touch-screen display and
the master power switch for the machine.
Power on the SPIDERSCREED™: Turn the
master power switch clock-wise from the OFF ( O )
position to the ON ( I ) position.
See the ELECTRONICS section for complete
instructions on the master power switch and the
MD4 display.
The SPIDERSCREED™ is powered by a 20.8 HP | 15.5
kW Honda GX630 engine. Refer to the Honda engine
booklet that comes with the machine.
The GX630 features:
• Digital CDI ignition system with variable timing
• A rev-limiter to protect against over-revving damage
• High capacity pump facilitates consistent oil delivery
• Automatic mechanical de-compression system
Refer to your Honda engine manual for the most current information, engine functions, and
maintenance/safety concerns. Perform the following inspection tasks each time you use your
SPIDERSCREED™:
• Check the general condition of the engine for any signs of damage, oil leaks, or fuel leaks.
• Check the fuel level. Never allow your engine to run out of fuel, since it may be necessary to
bleed air from the system to restart (see the engine manual for instructions, if necessary).
• Check the oil level. Running the engine with insu󰀩cient oil level can cause serious damage.
• Check the air lter. A dirty lter restricts air ow to the engine and reduces performance.

MACHINE COMPONENTS
The SPIDERSCREED™ includes a 10-
foot (3.1m) auger screed head for concrete
screeding.
The screed head features:
• Adjustable plow
• Hardened, double-ight auger
• Floating, vibrating nish blade
Each style screed head has bearings on
each end for the auger and/or roller. There
are also bearings used on the vibrate
assembly on top of the nish blade. It’s essential to grease the screed head after every 4 hours
of use, and also grease and clean of the screed head at the end of a job. These are high-wear
items, so you should always keep spares with you when screeding—in case of failure. The auger
guards are easily removed to assist with clean up.
Auger Screed Head
Leveling Actuators & Towers
The SPIDERSCREED™ is equipped with three
12V high speed, electronic actuators set control the
machine’s elevation. The towers are for supporting the
machine and drive units. The towers and upper and
lower bearings allow all the machine to perform its
unique system of driving and steering.

14
MACHINE COMPONENTS
Ligchine™ manufactures the SPIDERSCREED™ with a
state-of the-art, high-capacity, open-loop hydraulic system.
During normal machine operation, there are three key
elements that you should fully understand and monitor to
extend the life of your hydraulic system: uid temperature,
uid level, and ltration status. Learn more in the sections
below.
Hydraulic System
MINIMUM TEMPERATURE
Machine hydraulic uid temperature must heat up to a MINIMUM of 80° F (28° C) for
the machine to operate at peak performance.
While operating the machine, it’s important to frequently check the hydraulic uid temperature
as shown on the MD4 display. There is also a manual thermometer on the uid level sight
glass. Termperature is regulated by the thermostatically controlled 12V fan attached to a
radiator. The fan is set to turn on when hydraulic uid reaches 120° F (49° C).
Fluid Temperature
If the hydraulic uid temperature exceeds the maximum of 160° F (70° C),
immediately shut down the machine until you are able to determine the cause of the
overheating and correct it.
MAXIMUM TEMPERATURE

15
MACHINE COMPONENTS
Dirt and debris within a hydraulic system can cause serious damage to machine components. The
SPIDERSCREED™ features two contamination lter systems that require maintenance according
to the maintenance schedule. One lter system is a user-serviceable, high-ltration lter that is
accessible directly below the ltration gauge. Also, a magnetic suction lter built into the tank
removes any steel lings or debris from the hydraulic uid. Under normal circumstances, the
magnetic suction lter should last the life of the machine without the need for service.
In addition, the machine has an easy to read ltration gauge located on the top of the hydraulic
uid holding tank. Check it regularly to be certain that your system is performing as designed.
GREENGREEN band - full ow ltration, and no action is necessary.
YELLOWYELLOW band - full ow ltration is functioning, but at a pressure
level above normal. Replace the lter element very soon.
REDRED band* – the lter is in bypass, and the element requires
immediate replacement. Stop the machine and replace the lter.
*NOTE: During cold start situations, the lter may indicate a REDRED
condition for a few minutes until the uid temperature is normal.
If the pointer is in the:
Fluid Filtration
For convenience, use the integral uid level eyeglass on the
side of the hydraulic uid tank. It’s important to frequently check
the uid level to ensure that the level is resting in the middle of
the sight glass or higher.
If uid level drops below the middle point, add ISO 32 grade
hydraulic uid su󰀩cient to rell the tank and see the level rise
to the middle of the sight glass. Under normal circumstances,
the uid level should not decrease. A sudden uid level change
is a strong indication that a leak exists somewhere in the
system. It is urgent that you correct this immediately, since
operating the machine with low uid levels will impair proper
function. Also, low hydraulic uid level may pose a safety
threat, and could cause serious damage to the hydraulic
components.
Fluid Level Gauge

16
MACHINE COMPONENTS
This module, located on the front-center beneath the
shround, controls all hydraulic functions of the machine.
When it receives signals from the operator keypad, this
module interprets those signals and then sends electric
control instructions to specic hydraulic valves.
Following startup of your SPIDERSCREED™—and
during normal machine operation—you will see the LED is
blinking an amber color.
Any other combination of lights will indicate a malfunction.
In this case, contact Ligchine™ for troubleshooting advice.
Hydraulic System Controller
Hydraulic Manifold
The aluminum hydraulic manifold controls the
SPIDERSCREED™ drive and screed head
functions. The manifold houses a series of di󰀨erent
valves for each function. The drive functions use two
valves for speed and control. For in-depth diagrams,
please contact Ligchine™.

17
MACHINE COMPONENTS
The SPIDERSCREED™ has a state-of-the-art electronics system, and its important to take care
not damage it. The electronics system on this machine is industrial grade, and gaskets have been
placed at all wire junctions to minimize the impact of dust and moisture during normal use. For
complete protection, all wiring routes are under the hood and through protective shrouds. Under
normal circumstances, no maintenance is necessary.
SENSITIVE ELECTRONICS
The SPIDERSCREED™ electronics are very sensitive. You must disconnect
the machine battery prior to welding. Jump-starting the machine will destroy the
electrical system and void all warranties.
NO PRESSURE WASHING UNDER HOOD
Keeping your machine clean is important. You must exercise caution when pressure
washing your SPIDERSCREED™.
NEVER PRESSURE WASH ANYTHING UNDERNEATH THE HOOD.
Electronics System

18
MACHINE COMPONENTS
The SPIDERSCREED™ electronics system consists of several modules that connect together with
a series of wireless radios and wiring harnesses.
Primary electronic system components include the following:
• Battery – The primary, automotive-size battery is found
under the front-left of the hood and supplies power to all
machine wired components.
Keep the battery terminals clean and the battery charged.
During normal use, the voltage regulator will keep this
battery charged.
• Hydraulic system controller – Module that sends electrical
signals to actuate the hydraulic valves.
• Hydraulic Valve Solenoids & Connectors – These
solenoids and connectors are seen on each hydraulic
valve in the master hydraulic manifold. When a valve is in
operation, the connector illuminates to indicate which valve is
currently actuating.
• Power Distribution Control Center – Connects to all
electronic components providing fuse protection and relay
switching to distribute power to the other modules.
• Wiring harnesses – Connecting wire assemblies that
connect all modules to each other.
• MD4 Touch-Screen Display – The SPIDERSCREED™
