SECTION I
GENERAL DESCRIPTION
Lightning
A propane EFI engine powers the Lightning, driving a tandem
hydrostatic pump system, creating a (skid-steer) zero turn radius drive train.
Surface covering and coatings are removed by lowering a weighted blade onto
the surface and moving forward under a high torque drive system. A flexible
sharpened blade conforming to the floor surface then removes the surface
coating. The weight of the machine holds the blade firmly to the floor and
does not allow the blade to lift or ride over well-adhered surface coating
material, thus lifting the floor coating.

SECTION III
SAFETY AND PRECAUTIONS
Before operation of the Lightning please read the entire operation and safety manual with
complete understanding of the safety section. If you have any questions on safety and
precautions please call 1-866-636-7763.
There are several advantages to an effective safety program that include: lower operating costs,
lower workers’ compensations, less work time lost, high employee morale, and overall less
problems. No one can work safely without knowing what precautions to take to insure personal
safety. Operators must know what equipment to wear, which job practices are safe and which
are not, and must be aware of what hazards are possible in the work area. A regular schedule of
Preventive Maintenance on your equipment is the best protection against unpleasant surprises
that slow production and sometimes result in injuries. Here are a few suggested safety tips.
1. The first step before any maintenance or inspection takes place should be: stop
the engine and disconnect the battery terminals.
2. Wear proper eye and ear protection and heavy-duty work gloves at all times.
3. Practice good Preventive Maintenance.
4. Practice good housekeeping.
5. Allow the Lightning to come to a complete stop, turn off engine, and chock rear
wheels before performing any maintenance procedures.
6. Replace worn parts when necessary.
7. Do not reach into blade or control arm areas while machine is in operation.
8. Do not attempt to open any access door until the machine has come to a complete stop
and the engine and propane are turned off.
9. Be sure a qualified electrician does all electrical inspections or changes.
10. Loose surface coating can cause dangerous footing. Always be alert and careful.
11. After replacing parts, be sure all tools used are removed from the machine. Be sure all
bolts and nuts are tight. The loose connection of a rotating part could cause the part to fly
off with explosive force, causing serious damage to the equipment and possible injury to
the operator.
12. Always lower blade to the ground when the machine is unoccupied by the operator.
Serious bodily injury may result if arms are not in the lowered position when not
occupied.
13. Never allow unauthorized personnel or the general public into the work area.
14. The work area should be barricaded off to adequately keep all untrained persons out of
the work site. If an unauthorized person enters the work area, stop the machine
immediately and do not restart the machinery until they have left the work area.
15. Always allow a 200-foot buffer safety zone around all surface preparation activity.
16. Always run the Lightning in a well-ventilated area, with an approved OSHA air-
monitoring system in place at all times.

6
17. Read and obey all safety labels placed on the machinery at all times. If safety labels have
been destroyed or removed, call 1-866-636-7763 for free replacement prior to operating
the machinery.
18. The Lightning is not a toy. All operators must be over 18 years of age, must have read
and reviewed the safety and procedures manual before operating the machinery.
19. The Lightning is designed for surface preparation ONLY. It is not intended for towing,
pushing, or any other procedure not described in this manual.
20. Propane systems should be checked and documented twice yearly by a certified propane
professional for leaks or damaged parts. If a propane leak is detected, leave the machine
immediately and seek assistance from a propane professional. Do not use or restart
machinery until it is determined safe.
21. Horseplay and or high speed cornering is not allowed with this machine and could cause
rollover resulting in injury or death.
22. No smoking or open flame is allowed while machinery is running or within 50 feet of the
machine.
23. Operator must be sober, not under the influence of drugs or medication, and under full
control of all bodily senses while operating this or any machinery.
24. When transporting the Lightning it is recommended to use transport dolly. This
procedure spreads the weight of the machine over a larger surface area.
25. All Lightning operators must receive safety training before performing any functions
with the machine. OEM Products offers a free safety, maintenance, and orientation
seminar at its facility in Oklahoma City, OK.
New owners and operators are advised to call 1-866-636-7763 for an appointment.

START-UP AND BREAK-IN
The Lightning has been safety tested and run at our factory prior to shipping. The factory
topped off all fluid levels; however, the propane tank shipped empty. Here is a recommended
checklist of things to do before operating the Lightning:
1. Raise engine covers and check oil level.
2. Check air cleaner filter element for snug fit.
3. Check all battery cable connections for tightness.
4. Inspect for major hydraulic oil leaks. Snug hydraulic fittings using two wrenches. Use
caution not to over tighten.
5. Fill propane tank.
6. Mount propane bottle in brackets, be sure bracket alignment pin corresponds with
alignment slot on bottle.
7. Attach propane hose to liquid side of bottle by attaching to the handle valve. Snug fit the
female connector attached to the hose and slowly turn valve on. You should hear gas
briefly enter the propane hose. Immediately check for propane leaks with soapy water
solution. If leak persists after retightening the knurled female connector: STOP, turn off
the bottle at valve and seek assistance from a certified propane professional. Serious
damage and or an explosion could occur.
8. Check lug bolt torque: 85-100 lbs.
9. Return all engine guards to proper position.
10. Operator must be in seat before engine will start
11. Crank the engine by turning the key in the on position. The engine will crank for 3 to 5
seconds while the propane enters the carburetor. If the engine does not start, turn the key
off, wait 1 minute and try again. If again unsuccessful, check propane valve to be sure it
is open. If still unsuccessful, turn off propane valve and seek assistance or call 1-866-
636-7763.
12. Operation of the machine can continue when the engine is warming and running with the
operator safely in the seat.
Please turn to Section VI for Machinery Operation.
NEW MACHINE BREAK-IN
Since the Lightning is a very low maintenance and user-friendly machine, the only break-in is for
the Kohler engine. Please refer to the Kohler manual, the maintenance schedule can also be
found inside the air cleaner plastic cover.

SECTION VI
MACHINERY OPERATION
Before reading the machinery operation section, new operators should familiarize themselves
with VIEW#1 In-seat view and VIEW#2 Left and Right side detail. These pictures show the
basic parts of the Lightning.
To move the machine: Using the right hand, slowly move the Steering Joystick in the desired
direction. Forward and left moves the machine to the left, backward and right reverses the
machine to the right. It is just that simple to drive. The amount of movement on the joystick,
and the level of the throttle, controls the speed of the Lightning.
Throttle control is on the left side of the seat, taking the unit from idle to 3400
RPM. The optimum RPM is 2600 to 3200 RPM. To change the RPM of engine turn throttle
knob clockwise to lower RPM and counterclockwise to raise RPM.
The left joystick lever positions the blade to the surface. Moving the lever forward and backward
moves the blade up and down. Left and right movement changes the blade pitch.
To access the hydraulic reservoir: Lift up on the bottom of the seat
To change scraping
blades: Stop engine.
Loosen the smaller
Clamp Bolts at the rear
of the blade holder using
a ¾” open-end wrench.
Slide the dull blade out.
Loosen the Hold-Down
Bolts if necessary to fit
the replacement blade
against the Blade Step.
Retighten the Hold-
Down Bolts by hand and
then retighten the Clamp
Bolts with your wrench.
Lower the blade and
resume scraping. With a
little practice, you should
be able to change the
blades in 15 seconds. Dull blades may be sharpened and reused many times.
Operators should lower the blade by pressing the left hand lever forward each time they get off
the machine. This safety practice eliminates possible bodily injury from running into the blade
or lowering of the blade by unauthorized operators.

The Caster Wheel should not be in contact with the floor while scraping. The caster wheel will
lift off the floor when the blade is lowered. Caster contact with the floor while scraping will
negatively affect scraper productivity and steering. Caster wheel contact with hard debris while
scraping can damage the caster wheel and shorten its life.
