Air Supply and Connection  

 

  Hazards. 
 

Air under pressure can cause severe  

  injury. 
  Always shut off air supply, purge hose of 
  air pressure and disconnect tool from air 
  supply when not in use, before changing 
  accessories or when making repairs. 
  Never direct air at yourself or others. 
  Whipping hoses can cause serious injury. 
  Always check for damaged or loose hoses 
  and fittings. 
  Do not use quick disconnect 
  couplings at tool. For correct set up see  
  Figure 2 for correct set up. 
  When universal twist couplings 
  are used, lock pins must be installed. 
  Do not exceed maximum air pressure of 
  90 PSI or as stated on tool nameplate

.

Installation

Designed to operate on 90 PSI, lower 
pressure (below 90 PSI) will reduce 
performance of the tool while higher air 
pressure over 90 PSI raise the performance of 
the tool beyond its rated capacity and could 
cause serious damage to tool and user.

Always use clean dry air. Excessive moisture 
and dirt will greatly reduce the life of any air 
motor. We recommend the installation of an 
in-line filter-regulator-lubricator as close to 
the tool as possible.

Pre-Operation

Before the tool is connected to the air 
supply, clean the air hose of accumulated 
dust and moisture. Before removing a tool 
for service or changing accessories, make 

sure the air line is shut off and drained of air.

This will prevent the tool from operating if 
the throttle is accidentally engaged.

Operation

1.  Supply tool with 90 PSI of clean, dry air.  
  Higher pressure drastically reduces tool  
  life. Connect tool to air line using pipe,  
  hose, and fitting sizes shown in Figure 2.  
  Do not install a quick coupler directly into  
  the grinder throttle handle.
2. 

Operating Hazards 

 

Never mount a grinding wheel, cut off  

  wheel or router cutter on a die grinder  
  or tire buffer. A grinding wheel or other  
  accessory that bursts can cause very  
  serious injury or death. 
  Grinding accessory's rated speed must be  
  equal to or greater than the speed of the  
  die grinder. 
  Use only mounted wheels or tire buffing  
  accessories with adequate speed rating  
  and the correct shaft diameter. 
  Do not use wire brushes, drill bits, or any  
  other accessory other than mounted  
  wheels, burrs and tire buffing accessories. 
  Damaged, warn or incorrectly mounted  
  accessories can cause higher vibration.  
  To reduce exposures to vibration ensure  
  burring tools are sharp and this tool  
  and all accessories are in proper working  
  condition. 
  Ensure that the workpiece is properly  
  supported. 
  Avoid direct contact with rotating spindle  
  and accessory to prevent cutting of hands  
  or other body parts. Wear gloves to help  
  protect hands. Tool continues to run after  
  the throttle lever has been released. 
  Do not disable the lock off feature on the  
  throttle lever. 
  This tool and its accessories must not be  
  modified. 

  Operators and maintenance personnel  
  must be physically able to handle the  
  power of the tool and capable of  
  performing the job task. 
  Always wear impact-resistant eye and face  
  protection when involved with or near  
  the operation, repair or maintenance of  
  the tool or changing accessories on the  
  tool. 
  Gloves and protective clothing are  
  recommended. 
  Even small projectiles can cause eye  
  injuries and blindness. 
  Be sure all others in the area are wearing  
  impact-resistant eye and face protection. 
  Measure the air tool speed daily with a  
  tachometer to make sure it is not greater  
  than the RPM marked on the grinding  
  accessory. 
  Maximize the gripping length of the  
  accessory, it must not be less than .390 in.  
  (10mm). Increased overhang of a  
  mounted wheel reduces its permitted  
  speed - Refer to manufacturer's  
  recommendations and (ANSI B7.1).

Air Supply and Connection  

 

  Hazards. 
 

Air under pressure can cause severe  

  injury. 
  Always shut off air supply, drain hose of 
  air pressure and disconnect tool from air 
  supply when not in use, before changing 
  accessories or when making repairs. 
  Never direct air at yourself or 
  anyone else. 
  Whipping hoses can cause serious injury. 
  Always check for damaged or loose hoses 
  and fittings. 
  Do not use quick disconnect couplings at 
  tool. See Figure 2 for correct set up. 
  Whenever universal twist couplings 
  are used, lock pins must be installed. 
  Do not exceed maximum air pressure of 
  90 PSI or as stated on tool nameplate

.

Maintenance
Lubrication

Use an air line lubricator with Mobil Almo  
525 air tool oil (model 4ZF22), adjusted  
to two (2) drops per minute. If an air line  
lubricator cannot be used, add air motor  
oil to the inlet once a day.
