STORM
Battery Ride-On Floor Scraper
Instruction Manual
Rev 9.2019
READ MANUAL BEFORE OPERATING EQUIPMENT

General Description
The Storm is powered by an electric motor driving a tandem hydrostatic
pump system, creating a (skid-steer) zero turn radius drivetrain. 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 jump over well-adhered surface coating
material, thus lifting the floor coating.

SAFETY AND PRECAUTIONS
Before operation of the STORM please read the entire operation and safety
manual with complete understanding of the safety section. If you have any
questions about safety and/or precautions please call 1-866-636-7763.
A regular schedule of Preventive Maintenance on your equipment is the
best protection against unpleasant surprises that could slow production
and/or result in injuries. Here are a few suggested safety, operating, and
maintenance tips.
● Maintenance or inspection - Before performing any maintenance or
repairs.
○ Make sure the STOP button is pushed down.
○ Remove the cutting blade or lower it to the floor.
○ Chock the rear wheels.
● Wear proper eye and ear protection. Wear heavy-duty work gloves at
all times, especially when changing blades or attachments.
● Check machine daily for loose bolts or nuts and torque to the correct
torque specifications. For example, the center rear wheel motor axle
nut should be torqued to at least 200 ft/lbs. Not doing this could
cause the wheel and hub to fall off and would also cause the wheel
motor axle to be damaged, resulting in high replacement costs.
● Replace worn parts when necessary.
● Do not reach into blade or control arm areas while machine is in
operation.
● Be sure a qualified electrician does all electrical inspections or
changes.
● Loose surface coating can cause dangerous footing. Always be alert
and careful.
● After replacing parts, make sure all tools used are removed from the
machine.

● Always lower blade to the ground when the machine is unoccupied by
the operator to prevent unintentional bodily harm with the blade.
● Never allow unauthorized personnel or the general public into the
work area.
● 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.
● Always allow a buffer safety zone around all surface preparation
activity.
● The STORM is not a toy. All operators must be over 18 years of age,
and must have read and reviewed the safety and procedures manual
before operating the machinery.
● The STORM is designed for surface preparation ONLY. It is not
intended for towing, pushing, or any other procedure not described in
this manual.
● No smoking or open flame is allowed while machinery is running or
within 50 feet of the machine.
● Operator must be sober, not under the influence of drugs or
medication, and under full control of all bodily senses while operating
this machinery.
● When transporting the STORM it is recommended to remove the
cutting head and use a transport dolly. When set up properly, this
procedure spreads the weight of the machine over 6 points rather
than just 4 and allows you to get over door thresholds without
damaging them.
● Always park the STORM on a level surface and chock the wheels.
Not doing this could lead to the machine rolling away.
● Make sure to unplug the power cord before operating the STORM.
WARNING: Exposure to dust may cause respiratory ailments.
Potential Hazard

■ Possible employee exposure to nuisance dust during cutting,
grinding, machining, polishing, sanding, scraping, and so forth.
Possible Solutions
■ Identify exposure scenarios and perform appropriate evaluations.
○ Perform exposure measurements for the compounds
used.
○ Keep exposures below acceptable exposure levels.
■ Use wet operations when possible to reduce airborne dust
concentrations.
■ Provide appropriate ventilation to reduce dust concentration levels
in the air.
■ Use respiratory protection when necessary to further reduce
exposure and protect employees. [29 CFR 1910.134]
■ Maintain adequate housekeeping to remove unwanted dust and
reduce concentration levels.
BATTERY CHARGER INFORMATION
Delta-Q On Board Charger
Read this information in its entirety before using your on board Delta-Q
Charger. For technical support, please contact the manufacturer or
distributor of your vehicle or machine, as their version of this charger may
require unique operating instructions. For additional product documentation
please see www.delta-q.com/resources
Connect charger power cord to an AC outlet that has been
properly installed and grounded in accordance with all local
codes and ordinances. A grounded AC outlet is required to

reduce the risk of electric shock—do not use ground adapters or modify the
plug. Do not touch uninsulated portions of the output connector or
uninsulated battery terminals. Disconnect the AC supply before making or
breaking the connections to the battery. Do not open or disassemble the
charger. Do not operate this charger if the AC supply cord or DC output
cord is damaged or if the charger has received a sharp blow, been
dropped, or is damaged in any way. Refer all repair work to the
manufacturer, or qualified personnel. This charger is not intended for use
by persons (including children) with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge on electrical systems and
battery charging, unless they have been given supervision or instruction
concerning the use of the charger by a person responsible for their safety.
Children should be supervised to ensure they do not play with the charger.
● The charger may become hot during charging. Use hand protection to
safely handle the charger during charging.
● To maintain safe operations, the unit automatically reduces its output
power if the temperature rises above set thresholds, or if the AC input
voltage is too low. The charger will also reduce output power if it
detects that the battery pack is damaged.
● If power is interrupted, and then returns, the charger will start and
continue to operate without hazard to the user, or damage to the
batteries.
● Unplug the charger from both AC and DC sources when cleaning,
moving or conducting any maintenance or repair on the charger. No
user serviceable parts inside. Do not remove the cover due to the risk
of electrical shock.
● Do not expose charger to oil, dirt, mud or direct heavy water spray
when cleaning the machine.
● If the detachable AC input power cord set or DC output cord is
damaged, do not use the charger until they are replaced with cord
sets appropriate to your region and application.

● When mated with a Delta-Q sealed AC cord, the on board charger
meets IP66 specifications, making it dust-tight and protected against
powerful water jets. If a cord set with an unsealed connector is used,
the plug and connector must be periodically inspected to ensure the
contacts are clean and dry.
● If this charger is provided with an AC cord set and the power plug
does not match the power outlet, contact the equipment
manufacturer, distributor or Delta-Q Technologies for the correct AC
cord set terminating with a 3-prong plug suitable for your regions’
grounded power outlet.
● In North America (and other 120V AC regions), the AC cord must be
a 3 conductor UL Listed/CSA approved detachable cord set at least
1.8m in length (≥ 6 feet), minimum 16AWG and rated SJT; terminated
with 250V, 13A or greater connector.
● In 220-240VAC regions the AC cord must be a 3-conductor
safety-approved cord set, with 1.5mm² conductors(min.), rated
appropriately for industrial use. The cord must be terminated on one
end with a grounding type input plug appropriate for use in the
country of destination and both plug and connector should be rated
250V, 10A or greater.
● Extension cords must be 3-wire cord no longer than 30m (100’) at 10

Refer to the Delta-Q IC Series manual for more information and illustrations
as well as the Charger Error & Fault Codes Table.
Leaving the on board charger(s) plugged in will not harm the batteries and
is preferred as they will maintain and charge the batteries when needed.
The Lifeline® AGM batteries in your machine discharge 1 to 3% per month
and you do not want to store batteries for an extended period of time
without them being fully charged. The higher the temperature, the faster
the battery will self-discharge.

The Delta-Q on-board charger in your machine has been programmed to
charge the Lifeline® AGM sealed batteries that were installed originally
from the factory. If any other type of battery is installed on the STORM,
your charger profile may need to be changed.
Your STORM SS model will have 2 on board Delta Q Chargers. To be able
to use both of these chargers at the same time for faster charger, each one
has to be plugged into a different circuit otherwise it will trip a circuit
breaker from in the building due to too much amp draw.
Quick Charge Stand Alone Charger (included with the Storm
SS model only)
This model has a changeover tap to accommodate 208 or 230/240 volt
input. You must check your incoming power to the charger matches where
the changeover tap is placed for the charger to work correctly. Always use
a qualified electrician to install correct AC connections
Do not disconnect the plug from the Storm when the charger is on. The
resulting arcing could cause the batteries to explode. Do not expose this
charger to rain if possible.
Make sure the AC cord, DC output leads, terminals, and connectors are all
in good working condition. Do not use the charger if there are any signs of
stress or damage, or if wires are cut or have damaged insulation. Using
this charger with any of these symptoms could result in a fire, property
damage, or personal injury. Have a qualified service person make the
necessary repairs. See the Quick Charge Corporation Operating
Instructions for additional information and FAQs.

START-UP AND MACHINE OPERATION
Pre Start-Up
The STORM has been safety tested and run at the factory prior to shipping.
The factory topped off the hydraulic fluid but it should be checked just in
case something happened along the way. The fluid level should be about
2” from the top of the tank. Overfilling will result in fluid seeping out of the
hydraulic tank cap. Inspect for major hydraulic oil leaks. Snug any loose
hydraulic fittings using two wrenches if a leak is present. Use caution not
to over tighten. Make sure your lug bolts are torqued between 85-100 ft.
lbs. and the axle nut is torqued to 200 ft. lbs.
Start-Up
Lift the hood the seat is attached to and check that the circuit breaker is
switched to ON (non-SS models). Operator must be in the seat before the
electric motor will start. While you are sitting in the seat there is a red knob
on your right side, behind the steering joystick. Pull that red knob up and
you will hear the electric motor start turning. The battery gauge is behind
the red knob and will first display the hours recorded on the gauge. The
Storm SS model will have a black throttle dial next to the red knob. This
should be set to the “OFF” position while initially pulling the red knob up.
The electric motor will still turn while in this position. Then turn the black
dial clockwise until desired motor speed is achieved. Note the machine is
much slower when the dial is at a low #. This is desirable while loading or
unloading the Storm SS on a trailer or while driving through a doorway or
tight space.

Operation
Use the 2 levers between your legs (or the left hand joystick in the 2020+
models) to position the transport dolly or blade where you would like them
before moving. Level the top of the transport dolly horizontally or parallel
with the floor for it to function correctly and not peel the coating off the
caster wheels. Push the joystick on your right side in the direction you
want to go to get moving. You always want to start out scraping with the
blade or Tile Tooth as parallel to the floor as possible while still being able
to stay under the material being taken up. You then increase the pitch of
the blade or tooth as necessary to maintain productivity. While scraping on
top of concrete you can flip the scraper blade over when it gets dull and the
other side of the blade will have the desired bevel for additional take up.
You can do this by pushing down on the right handle between your legs (or
pulling backwards if your machine has the left hand joystick) to extend the
caster wheels which will in turn raise the front of the machine enough to be
able to spin the blade holder. After you do this make sure that you retract
the front caster wheels and keep them off of the floor while scraping. This
ensures maximum weight on the front blade as well as extending the life of
your front caster wheels. Remember, when you push down the red button
to stop the machine for parking, to make sure it is on a level surface and
chock the wheels to prevent the machine from rolling away.
Your Storm is equipped with wheel scrapers that scrape whatever debris
you run over like VCT off the tires. If you notice your Storm isn’t getting
traction or is carrying debris around you may have to loosen 2 bolts on the
wheel scrapers and slide them against the tires and retighten.

BATTERY CARE AND MAINTENANCE
DANGER OF EXPLODING BATTERIES
Lead acid batteries can produce explosive mixtures of hydrogen and
oxygen. Take the following precautions:
● Never leave batteries in an airtight or sealed enclosure.
● Charge batteries in accordance with the instructions given in this
manual.
● Keep all sparks, flames and cigarettes away from batteries.
● Make sure cables are tightly connected to terminals to avoid sparks.
● Wear proper eye and face protection when installing and servicing
batteries.
DANGER OF CHEMICAL BURNS
Lead acid batteries contain sulphuric acid electrolyte which can cause
severe burns to body tissue. Take the following precautions:
● Avoid contact of the electrolyte with skin, eyes or clothing.
● Never remove or damage vent valves.
● In the event of an accident, flush with water and call a physician
immediately.

DANGER OF BURNS IF TERMINALS ARE SHORTED
Lead acid batteries are capable of delivering high currents if the external
terminals are short circuited. The resulting heat can cause severe burns
and is a potential fire hazard. Take the following precautions:
● Do not place metal objects across battery terminals.
● Remove all metallic items such as belt buckles, watches, bracelets
and rings when installing or servicing batteries.
● Wear insulating gloves when installing or servicing batteries.
● Use insulated tools when installing or servicing batteries.
DANGER OF THERMAL RUNAWAY
Thermal runaway is a condition in which the battery temperature increases
rapidly resulting in extreme overheating of the battery. Under rare
conditions, the battery can melt, catch on fire, or even explode. Thermal
runaway can only occur if the battery is at high ambient temperature and/or
the charging voltage is set too high. Take the following precautions:
● Charge batteries in accordance with the instructions given in this
manual.
● Do not install batteries near heat sources or in direct sunlight that
may artificially elevate their temperature.
● Never use another charger not designated by the manufacturer -
OEM Products Inc.
As of this writing, Concorde does not know of any Lifeline® AGM batteries
that have failed due to thermal runaway. See the LIFELINE® TECHNICAL
MANUAL for full SAFETY INFORMATION.

TEMPERATURE CONSIDERATIONS
The temperature of the battery has a significant impact on its performance
and life capability. Battery capacity is reduced significantly in cold
temperatures.
It should be realized that the temperature of the battery itself and ambient
temperature can be vastly different. While ambient temperatures can
change very quickly, battery temperature change is much slower. It takes
time for the battery to absorb temperature and it takes time for the battery
to relinquish temperature.
If the battery is exposed to cold climates, the state of charge should be kept
at a maximum to prevent freezing of the electrolyte. A fully charged battery
will not freeze even under the coldest weather conditions, but a discharged
battery will freeze even when moderately cold.
Frozen batteries are not capable of charging or discharging except at very
low rates, and may be permanently damaged by expansion of the
electrolyte. A battery pack with a state of charge of 25% can freeze at 9
degrees Fahrenheit or a battery pack ran all the way down to cutoff can
freeze at 21 degrees Fahrenheit. A 100% charged battery pack would
have to get colder than -94 degrees Fahrenheit to freeze.

SERVICING
Lifeline® AGM batteries do not need electrolyte additions as do flooded
lead-acid batteries, but periodic servicing is essential to assure continued
integrity of the battery system. Servicing should include good record
keeping to document the life history of the battery system and to identify
whether corrective action needs to be taken. See the LIFELINE®
TECHNICAL MANUAL for full Servicing schedule.
CHARGING
You can not short charge your batteries (like at lunchtime) without
long-term effects on your batteries. It is important to charge batteries back
to 100%.
When you have a fully charged battery it is lead and sulfuric acid (Active
material). When you start discharging a battery, the chemical reaction
between lead and sulfuric acid provides energy for your application. The
byproduct of this reaction is lead sulfate. Lead sulfate is a soft material that
naturally covers the plates, both positive and negative, when the battery is
being discharged. The deeper the discharge, the more lead sulfate will
cover the plates. Once the load is turned off and it is time to recharge, lead
sulfate is easily converted back into lead and sulfuric acid. This is why it is
important to charge batteries back to 100%. If you don’t you will not convert
all the lead sulfate back into the active material. If a lead acid battery is not
immediately recharged, the lead sulfate will begin to form hard crystals,
which cannot be reconverted by standard charging voltages. The longer
this goes on, the harder it is to get all of your capacity back.

MACHINE MAINTENANCE
DAILY MAINTENANCE
● Check hydraulic oil level in tank by removing the filler cap and
ensuring the oil level is within 2 inches of the top of the tank.
● Inspect for hydraulic leaks
● Retorque Wheel lug bolts to 100 ft/lbs. and Axle nut to at least 200
ft/lbs.
EVERY 100 HOUR MAINTENANCE
● Grease caster bearings (front wheels). There are 2 grease zerks for
each of the 2 front caster wheels.
EVERY 250 HOUR MAINTENANCE
● Change the hydraulic oil (approximately 3 gallons) with 15w-50 Full
Synthetic motor oil. Replace hydraulic filter. (part # SMH-006)
