The DiamaPro SCAR-10 can be operated outdoors within the tempera-ture range of 41°F to 86°F (5°C to 30°C). It’s crucial to avoid using the machine during rainy or snowy weather conditions. When using the ma-chine indoors, make sure to work in areas that are adequately ventilated.

PROTECTION DEVICES

The machine is equipped with multiple safety mechanisms. These con-trivances safeguard the operator and any other individuals from potential harm. It is imperative not to remove them. Instead, prior to utilizing the machinery, ensure that all safety devices are appropriately installed and operational.

USAGE SAFETY

The DiamPro Systems SCAR-10 is intended to minimize all associated hazards related to its operation. Nonetheless, it is not entirely feasible to eliminate the possibility of accidents with the machine. Inexperienced or untrained operators may cause residual risks associated with:

• Positional hazards due to improper operator posture
• Entanglement hazards arising from the use of unsuitable work attire
• Training hazards caused by insufficient operational training

SAFETY MEASURES FOR PROPANE

Propane is a flammable gas with vapors that are denser than air. Similar to gasoline, improper handling of propane can lead to explosions. To aid in de- tecting leaks, propane is mixed with an odorant that has a distinctive smell, detectable at low concentrations. When working with propane, it is essential to be aware and take necessary safety precautions. As long as these mea-sures are observed, the risk is minimal. However, lack of awareness could result in needless hazards. The two most significant dangers associated with propane- powered floor care machines are:

• Carbon Monoxide Poisoning :
  Carbon monoxide poisoning is the most commonly reported incident associated with propane-powered floor care machines, caused by exces-sive exhaust emissions. The symptoms include headaches, dizziness, and nausea. Engines with inadequate preventive maintenance practic-es, particularly those with unclean air filters and machines operated in enclosed spaces without sufficient ventilation, are a significant cause. The use of substandard, inexpensive machines without emissions control technology and improperly adjusted carburetion could also contribute to the problem.

• Overfilled Fuel Cylinders:
  Almost all fire-related incidents reported occur when a cylinder is brought into a building without first checking for overfill. This practice is hazardous, imprudent, and avoidable.

• SAFETY AGAINST FIRE
  Be mindful of the potential risks of fire or explosion when working with propane and take standard fire-safety measures.

• Fire:
  There is a likelihood of fire resulting from leakage or venting of LPG vapor from fuel cylinders or carburetion equipment.

• Explosion:
  Concentration or confinement of LPG vapor in a restricted or small space may cause ignition or explosion.

• Propane may also experience a BLEVE: Boiling Liquid Expanding Vapor Explosion.

• EMISSIONS

All propane-powered floor care machines generate emissions. While most are innocuous, some can be hazardous, even fatal. Carbon monoxide (CO) presents the most significant danger since exposure to CO at a concentration of 3,000 parts per million (ppm) for as little as 30 minutes can be lethal. Carbon monoxide is a colorless, odorless, and invisible gas formed when fossil fuels, including propane, gasoline, wood, coal, oil, and methane, burn incompletely.

• National Fire Protection Agency (NFPA)
  • To operate a propane-powered floor care machine safely, it is neces-sary to adhere to specific safety regulations. The NFPA is responsible for ensuring safe propane use and storage, and their Standard for Storage and Handling of LP Gas should be consulted for guidance. Copies of this publication can be obtained by contacting the NPFA in Quincy, MA at 1-800-334-3555.
  • One important regulation set forth by the NFPA #58 is that all personnel who handle propane gas must be properly trained in its safe handling and operation procedures and carry a certification from their employer or training supervisor attesting to this fact.
  • While this requirement primarily applies to individuals who fill and transport liquid propane gas, Diama-Pro® Systems recommends that operators of propane-powered floor care machines in public areas also receive proper training and certifica-tion. Although NFPA 58 8-4.5 permits the use of propane-powered floor care equipment in buildings frequented by the public, including when they are occupied, DiamaPro® Systems suggests that these machines be used when occupancy is minimal.
• California Air Resource Board (CARB) & Environmental Protection Agency (EPA)
  • While CARB and EPA establish limits for propane-powered engines used outdoors, it is important to note that approval from CARB/EPA does not indicate that the engine is safe for indoor use.
• Canadian Gas Association (CGA)
  • A limit of 1500 ppm CO in exhaust flow has been established by the CGA.
• Occupational Health and Safety Administration (OSHA)
  • When it comes to propane-powered machines utilized indoors, OSHA has implemented an 8-hour time-weighted average (TWA) limit of 50 ppm CO in ambient air. OSHA is also contemplating the establishment of a limit of 800 ppm CO in exhaust flow.
• Department of Transportation (DOT)
  • Regulations have been set forth by the DOT regarding the safety of fuel cylinders, including those utilized on propane-powered floor care machines.
• Local Agencies
  • Before granting approval for the use of certain equipment, local law enforcement agencies such as the Fire Marshall may rely on independent testing laboratories like UL and CGA. These labs conduct extensive testing of equipment and only issue their approval after a rigorous evaluation process. While not mandatory for all law enforcement agencies, the stamp of approval from these organizations serves as an additional assurance for operators that they are working with and around safe equipment.

PERSONAL PROTECTIVE EQUIPMENT

When operating the machine, it is important to:

• Wear safety shoes at all times.

• Wear ear protectors to safeguard your hearing.

• Ensure that all personnel in the immediate work area wear safety
  glasses with side shields.

• Wear safety gloves when changing tools.

• Dress appropriately for the work environment.

• Use Carbon Monoxide monitors as an additional precaution.

TESTING:

Numerous tools are available in the market for detecting toxic gases. However, only the ones specifically designed for detecting carbon monoxide resulting from combustion engines are deemed suitable for testing exhaust emissions from floor machines powered by propane. Certain instruments are meant for detecting “ambient air” and may get damaged if utilized for taking readings in the muffler or tailpipe. Hence, it is crucial to select the appropriate instrument to fulfill the testing requirements. In general, instruments that can detect readings in ppm (parts per million) ranging from 0 to 1000 are sufficient for examining ambient air, i.e., the air in the breathing zone of the operator. On the other hand, devices capable of testing carbon monoxide in the exhaust shoudl be certified by the manufacturer for that purpose and should be able to read from 0 to at least 2000 ppm.

Several instruments and systems for these purposes include:

1. AMBIENT AIR MONITORING
   • DRAGER Model 190 manufactured by National Drager
   • SENSIDYNE gas sampling system with YB-11038 Sensidyne detector tubes
   • DRAGER gas sampling system with YB-4620 Drager detective tubes
   • GAS-TECH Model CO-95
   • ENERAC POCKET 60 manufactured by Energy Efficiency System
2. ENGINE EXHAUST ANALYZERS
   • HORIBA GAS ANALYZER
   • ENERAC 2000 COMBUSTION ANALYZER
   • ENERAC POCKET 60
3. DATA LOGGERS
   • INDUSTRIAL SCIENTIFIC CORP. MODEL STX-70 CO MONITOR, Data-Logger
   • BIOSYSTEMS INC. “TEXILOG” Data-Logger

All instruments used for testing must be calibrated at the intervals recommended by the manufacturer. The test results must include the monitor’s model number and date of calibration.

SPECIFICATIONS

OPERATION INSTRUCTIONS

IMPORTANT: Read the engine manufacturer’s manual, familiarize yourself with engine start procedures.

BEFORE STARTING THE ENGINE:

Be sure that the cutter drum assembly has been properly installed and the cutter drum shaft is in place and secured.

1. Select a level place at the job site. Set the “Handle Wheel” in the full counter-clockwise or UP position. It is most important to determine the position of the cutter wheels as they relate to the slab or floor surface. If the drum assembly is filled with cutters, the cutter wheels will most likely contact the slab when the “Handle Wheel” turned clockwise or down. Pull the “Engagement Handle” towards the operator to ensure the cutting drum will not contact the slab when attempting to start the machine. Always raise the Engagement Handle before starting the machine to prevent accidental damage to the machine and the slab.
2. Turn the “Handle Wheel” to the full counter-clockwise position and raise the machine. DO NOT force the handle wheel. If resistance is felt, turn the “Handle Wheel” clockwise one or two turns. This will allow the “Handle Wheel” to reach its normal full UP position.
3. Check level of oil in engine crankcase (engines are usually shipped dry, oil must be added as per engine manufacturers instructions).
4. Check fuel level (follow engine manufacturers instructions).
5. Be sure all guards (belt, motor, cutter wheel) are in place and secure.
6. Be sure the emergency stop switch is fully seated and attach the end of the cord to a secure piece of clothing before operation
7. Raise the throttle about half way and turn the ignition key clockwise to start the machine.
8. If utilizing the pull starter, determine the starter rope pulls easily, and the rope retracts properly.

BEFORE STARTING THE MACHINE

• Perform a visual inspection of the entire machine and all daily maintenance according to the Maintenance Schedule.
• Locate and be familiar with all engine/motor and operating controls.
• For Gasoline models, obtain the Engine Manufacturer’s Owner’s Manual. Read it and understand it before continuing. Follow the engine manual for break-in instructions.
• Use the correct cutters for the job. Be sure cutter drum is balanced, the number, size and type of cutter wheels are correct and the cutter drum shaft is locked and secured.
• Be sure all fasteners are tight and secure, check for signs of metal cracking or fatigue, inspect for damage to electrical wiring, damage to fuel lines, check bearings, etc.
• Be sure all guards are in place. Do not operate unless cutter drum guard is in place and secure.
• Inspect work area to determine the presence and location of deck inserts, pipes, columns and objects protruding from the slab surface so that they may be avoided during operation.

STARTING THE ENGINE/MOTOR

Warning

• DO NOT OPERATE GASOLINE/PROPANE POWERED EQUIPMENT WITHOUT ADEQUATE VENTILATION.
• CARBON MONOXIDE IS AN INVISIBLE, ODORLESS GAS THAT CAN KILL.
• Consult the Engine Manufacturer’s Owner’s Manual and follow the directions for starting the engine and allow the engine to warm up.

Danger

• NEVER CHECK FOR PROPANE LEAKS USING AN OPEN FLAME. INSTEAD, USE A LEAK-TESTING SOLUTION. NEVER ALLOW PROPANE FUMES TO ESCAPE IN A  CLOSED AREA; PROPANE IS HEAVIER THAN AIR AND WILL“SETTLE.”
• To start this propane powered equipment, open the main fuel valve  located on the propane tank. Open the throttle wide open and start the engine.

NOTE: Always turn off the main fuel valve on the propane tank when equipment is not being used.

WARNING: ALWAYS BE SURE TO UTILIZE THE SAFETY STOP SWITCH AND FASTEN THE STOP SWITCH LEAD TO A SECURE PIECE OF CLOTHING.

STARTING THE CUT

• Slowly lower the cutter head to the slab surface with the engagement handle
• When cutting, be sure to engage the handle wheel lock. This will ensure the depth of cut does not change due to vibrations.
• Rotate the Depth Control down until you hear the cutters contact the slab. Once contact is made lower the machine an additional 1/8” for the initial pass. Additional passes can be made in 1/8” increments to a maximum depth of 3/8”. Cutting more than 1/8 per pass could result in damage to the drum and machine.
• Use an Industrial Vacuum Dust Control System for dry planing operations.

TO STOP CUTTING

• Move engagement handle toward the operator to raise cutter head assembly above slab surface.
• For gasoline and propane models, close throttle and turn the ignition switch to the “OFF” position.

AFTER CUTTING

• At the end of the day, clean the entire machine after it has cooled. Check for worn or damaged cutters and perform any required maintenance.

CUTTING HEADS / DRUMS

• Drum assembly revolves at approximately 1200-1800 R. P. M.; Push Model Scarifier/Planer is a down-cut planer, Depth of cut is completely determined by the material to be cut, horsepower of the engine/motor and spacing of the cutter wheels on the cutter head.
• All cuts should be started from a stationary position – when the cutting depth is reached the planer should then move forward.
• The engine/motor should not labor. Run at full speed and adjust forward speed to fit the work being performed. Very hard concrete will have to be cut at a slower pace than asphalt or deteriorated surfaces.
• If it is necessary to make deep cuts – make several shallow cuts to achieve the desired depth. If the cutting depth is set too deep the cutter wheels will not be able to absorb the shock and damage to the equipment will result.
• The cutter wheels have an oversized arbor hole. This “play” is needed to absorb some of the shock of the cutter contacting the concrete.
• Cutting speed is directly proportional to the amount of material to be removed in one pass; an example – cutters spaced on 1” centers will penetrate to a greater depth than those spaced at 1/2” centers, and the planer will move forward faster. Most of the material in the path of the cutting head will be removed either by the cutters them selves or through the natural hammering action and spalling of the material being cut. A later pass with cutters spaced closer together will remove the ridges.

TO REACH MAXIMUM DEPTH IN CONCRETE

• It is best to make several passes – increments of 1/32-1/8” or even less if surface is extremely hard.
• Use coarse (wide spacing) for initial passes. Complete job with medium spacing. Never use a fine spaced cutter head to cut deeper than 1/32-1/8”.
• Some concrete slabs, especially if they are covered with water a good deal of time or if they have been treated with hardeners, develop an extremely high surface strength. Material removal depth should not exceed 1/32-1/8” per pass thus requiring several passes to reach the desired depth of cut.

TO CUT ASPHALT

• This surface can be easier to penetrate than concrete. In some instances depths of 1/4” per pass can be achieved with the larger ma-chines. In general though, 1/8” per pass is still standard and should be maintained until the hardness of the asphalt is determined.
• Note: Specific information on asphalt cutting is available upon request.

FINE CUTTING

• This assembly should be used for very shallow or cleaning operations. Check with DiamaPro® Systems or an authorized dealer for special cutter wheels for removal of paint build-up or similar surface coatings.

MAINTENANCE

Refer to the Engine/Motor Manufacturer’s Owner’s Manual for maintenance information specific to the engine/motor used.

caution

Never work on or under equipment without first securing the equipment to prevent it from moving or falling. Always work on a flat and level surface.

IMPORTANT

• Check oil level before operation. Change engine oil and filter according to engine manufacturers recommendations.
• Clean air filter element daily.

BELTS

On new equipment, and after replacing a set of belts, they should be re- tensioned after the first four hours of use.

• New belts will be stiff and will loosen with use. Proper belt tension must be maintained to transmit the engine/motor power to the cutting drum. Slipping belts will overheat, belt life will be shortened and the cutting speed limited. Over tensioned belts will shorten belt and bearing life.
• Damaged, stretched or excessively worn belts should be replaced with a complete set. DO NOT mix new and used belts, doing so will only shorten the life of new belt(s) and limit power transfer from the engine/motor to the cutting drum. This will have a definite impact on machine efficiency and production rate.
• To tension belts, loosen motor mounting hardware slightly. Use the jacking bolt to adjust the engine/motor until the belts are tight. Re-torque the engine/motor mounting hardware.

CUTTER ASSEMBLY BEARINGS

• Grease cutter assembly with one pump of a lithium complex grease (XHP222 or equivalent) after every 4 hours of use.

BLADES & DRUM REMOVAL/REPLACEMENT

CUTTING DRUM ASSEMBLY

CUTTING DRUM INSTALLATION

1.  Be sure the machine is turned off with the battery disconnected with the key switch in the off position. Remove the safety switch tether for added protection.
2. Engage the parking brake to ensure the machine does not move during this operation.
3. 2. On the right side of the machine, opposite from the belted side, remove the bottom 2 socket head bolts from the bearing plate using an M10 Allen set.
4. Remove the top 2 bolts using an M18 Wrench.
5.  To remove the plate from the machine, thread the 2 socket head bolts into the threaded holes on the left and right of the bearing plate. Be sure not to cross-thread these holes.
6. Gently tighten the bolts one after another, a few turns at a time, to press the plate off of the shaft.
7.  Slide the drum off of the shaft carefully, so as not to damage the shaft.  Set up your drum profile as desired.

• Slide the new drum back onto the shaft. Be sure that the drum is fully seated onto the driving plate, and the spacer (A) is fully seated against the drum.
• Using the guide pins (A), reattach the bearing plate to the machine using the bolts previously removed. Be sure the bearing is seated onto the shaft. It may be helpful to lower the machine so that the drum is touching the ground taking the load off the shaft allowing easier alignment of the holes.
