     safeTy InsTRuCTIons foR PoWeR T ools 
    1. KnoW  youR PoWeR T ool.    Read  owner’s  manual  carefully.  
    Learn  its  applications  and  limitations  as  well  as  specific  potential 
    hazards particular to this tool. 
    2.  KeeP WoRK  aRea Clean.  Cluttered  areas  and  benches  invite 
    accidents. 
    3.  aVoID DanGeRous enVIRonmenTs.  Keep work areas as dry 
    as  possible.    Do  not  use  tool  in  presence  of  flammable  liquids  or 
    gases.  Keep the area well lit. 
    4.  KeeP C hIlDR en an D VIsIT oRs aWay .  All visitors should be kept 
    a safe distance from the work area. Keep out of reach of children.   
    5.  Don’T  foRCe T ool.  It will do the job better and safer at the rate 
    for which it was designed. 
    6.  WeaR PRoPeR aPP aRel.  Do not wear loose clothing or jewelry 
    as it can get caught in moving parts. Rubber gloves and insulated 
    non-skid footwear are recommended.  Wear protective covering to 
    contain long hair. 
    7.  WeaR PRoPeR eye PRoTeCTIon.     All  users  and  bystanders 
    must always wear proper personal eye protection which conform with 
    ANSI/ISEA Z87.1 (CAN/CSA Z94.3). Also use a face or dust mask if 
    operation is dusty. Always wear certified safety equipment.  
    8.  WeaR PRoPeR eaR PRoTeCTIon.    All  users  and  bystanders 
    must wear proper personal ear protection which conforms with ANSI 
    S12.6 (S3.19) hearing protection.  
    9.  WeaR PRo PeR Res PIRaTo Ry PRo Te CTI on.  All  users  and 
    bystanders must wear proper personal respiratory protection. Always 
    use NIOSH/OSHA approved respiratory protection appropriate for the 
    dust exposure.             
                
    Warning: Some dust created by power sanding, sawing, grinding, drilling, 
    polishing and other construction activities contains chemicals known to the 
    State of California to cause cancer, birth defects, or other reproductive harm. 
    Some examples of these chemicals are:  
        
     - Lead from lead-based paints         
     - Crystalline silica from bricks, cement and other masonry products, and    
     - Arsenic and chromium from chemically-treated lumber.   
                   
    						
    							5
    Your risk from these exposures varies, depending on how often you do this 
    type of work. To reduce your exposure, work in a well ventilated area, and 
    work with approved safety equipment, such as dust masks that are specially 
    designed to filter out microscopic particles.      
             
    To  familiarize  with  the  risks  associated  with  a  material,  consult  with  your 
    employer,  manufacturer/supplier  and  government  agencies  regarding  the 
    hazards of the materials and their recommendations to protect yourself.

    grease.  Inspect moving parts for alignment and binding as well as 
    for breakage and improper mounting. 
    16.  aVoID  aCCIDenT al sT aRTInG.    Do not carry a “connected” tool, 
    or make adjustments, or change discs without making sure the tool 
    is disconnected from the air supply.
    17.  use  only  ReCommenDeD  aCCessoRIes. The  use  of  any

    In addition to the general safety notes described on the preceding pages, 
    please read and observe the following precautionary notes before using 
    the pneumatic stone cutter.
      DANGER!
     INSTruCTIONS
    Alpha Professional Tools® provides the highest quality parts and manufactur-
    ing techniques in the manufacture of this tool. In order to obtain the maximum 
    effectiveness and provide the highest degree of safety, it is necessary to 
    review and follow these instructions carefully before using the tool.
     SAFETy AdvICE
    •  Please note safety instructions on Page 4-5.
    •  Always disconnect the air line before making any changes to the set-
    tings or carrying out maintenance.
    •   Keep water and air lines clear from working range of the machine.  These 
    lines should always lead away from you and behind the operating area.
    •  Before  use,  check  the  machine,  hose  and  fittings  for  any  damage  or 
    material fatigue, only authorized service agents should carry out repairs.
    •  Always wear safety glasses and respiratory protection when working 
    with  this  machine.    It  is  further  recommended  to  wear  safety  gloves, 
    apron, as well as sturdy non-slipping shoes.
    •  Only use saw blades whose permitted speed is at least as high as the 
    highest no-load speed of the machine.
    •  Be sure saw blade fits the tool properly and securely. Do not modify the 
    tool to force fit the blade. For example, do not remove blade guard.
    •  Check blades before use.  The saw blade must be properly mounted 
    and turn freely.  Perform a test run for at least 30 seconds without any 
    load.  Do not use damaged, out of round or vibrating blades.
    •  Immediately switch off the machine in case of considerable vibrations 
    or if other malfunctions occur.  Check the machine in order to find out 
    the cause.
    •  Always use and store the saw blades according to the manufacturer’s 
    instructions. The flange bolt must be tightened before starting to work 
    with the machine.
    •  The work piece must be secured if it is not heavy enough to prevent 
    movement.
    •  The tool is designed for cutting on horizontal surfaces.

     aIR PRessuRe anD Volume
    The  recommended  air  pressure  for  this  stone  cutter  is  90  PSI. The  most 
    important factor in running this stone cutter is the volume of air being sup-
    plied to the stone cutter. The volume is the air consumption needed to run 
    this stone cutter at a constant speed under light downward hand pressure. 
    The volume is measured in CFM (cubic foot per minute (ft
    3/min)). You need 
    a  minimum  of  32  CFM  to  run  this  tool  at  the  1  HP  rating.   Alpha®  recom-
    mends running the tool at the maximum flow volume of 48 CFM to get the 
    full 2 HP rating out of the stone cutter. 
    It  is  also  very  important  to  keep  your  air  cool,  dry,  and  clean,  so  look  for 
    a compressor with a refrigerated dryer and high-efficiency filter built-in or 
    purchase  a  separate  air  dryer  and  filter  unit  rated  for  your  compressors   
    CFM.   (See page 11 for Alpha

    from rusting when not in use)

    noT In use.
    At the end of each workday, place 5-6 drops of rust inhibitor oil (included 
    with each stone cutter) into the tool using the oil port.  Depress the throttle 
    lever  varying  the  speed  from  very  low  to  half  speed,  for  a  minute  or  two.  
    This  will  allow  the  oil  to  transition  into  the  rotor  assembly  and  coat  the 
    inside of the tool.  
     CleanInG The RoT oR assembly
    Over time, the rotor assembly can fill up with oil sludge, vane dust residue, 
    and contamination and will need to be cleaned.  To accomplish this remove 
    the muffler assembly from the tool to allow the waste to exit.  You can hold a 
    paper towel over the exit port to reduce the sound level and catch the exit-
    ing waste.  Add 10 to 20 drops of oil to the oil port and run the tool varying 
    the speed from very slow to half speed for two to three minutes to allow the 
    oil to process through the machine.  Check the paper towel for exit waste, 
    continue until there is little to no exit waste.
    Run the tool at its slowest speed.  If the tool sounds like it is running with 
    a variation in speed, this is an indication that one of the vanes is still stick-
    ing in the rotor.  Repeat the process to see if this will correct the variation 
    in  sound.    If the  problem  continues,  contact  an  authorized Alpha
    ® Repair 
    Center for routine repair and maintenance.
