b.Higher material removal rates can sometimes be achieved by making a series of shallow passes 90 degrees to each other to form a waffle like pattern. This technique is especially useful when removing deeper accumulations of rubber, paint, dirt debris, etc. from industrial floors.
5)The grinding process on many work surface materials can produce sparks, dust and other foreign particle contamination.
DANGER
SPARKS PRODUCED BY THE ACTIONS OF MULTI- ACCESSORY OPTIONS AGAINST THE WORK SURFACE (FOR EXAMPLE: STRIKING ANCHOR BOLTS) MAY COME IN CONTACT WITH MATERIALS THAT CAN RESULT IN A FIRE AND/OR EXPLOSION. THIS OCCURRENCE CAN RESULT IN PROPERTY DAMAGE AND/OR PERSONAL INJURY.
DANGER
THE CREATION OF DUST AND OTHER FOREIGN PARTICLE CONTAMINATION FROM THE OPERATIONAL PROCESS CAN RESULT IN PROPERTY DAMAGE AND/OR PERSONAL INJURY. FOR SUCH OPERATING CONDITIONS, ALWAYS WEAR A NIOSH/MSHA APPROVED DUST/MIST RESPIRATOR. CONSULT APPLICABLE OSHA REGULATIONS FOR SPECIFIC INFORMATION.
6)Dust and other particle contamination can be controlled by the following methods:
a)The SURFACE GRINDER is equipped with a 3 inch outside diameter vacuum tube adaptor located at the rear of the machine. An industrial type vacuum system and front shield assembly can be attached to the SURFACE GRINDER to remove/control dust and other particle contamination from the work surface. A hose clamp is sometimes required to properly secure the vacuum hose to the vacuum tube. FIGURE 39.

DANGER
ALWAYS UTILIZE AVACUUM SYSTEM DESIGNEDTO OPERATEWITHINTHE SPECIFIC JOB SITE REQUIRE- MENT. DUST MATERIAL CAN MEET CLASS II OR CLASS III SPECIFICATIONS OFTHE NATIONAL ELEC- TRIC CODE® FOR HAZARDOUS LOCATION CLASSIFICATIONS.CONSIDERATION MUST ALSO BE GIVEN TO THE CREATION OF HAZARDOUS TYPE MATERIALS REQUIRING SPECIFIC DISPOSAL PRO- CEDURES. DETERMINETHATTHEVACUUM SYSTEM IS PROPERLY DESIGNEDTO OPERATEWITHINTHESE ATMOSPHERES. CONSULT CURRENT NATIONAL ELECTRIC CODE®, OSHA AND ENVIRONMENTAL PROTECTION AGENCY REGULATIONS FOR SPECIFIC INFORMATION.
b)Water/sand slurry mixture applied directly to the work surface can be an effective method of reducing the effects of grinding and other material removal processes. This method can be a productive alternative when removing adhesives containing asbestos. A negative effect of this method is that the water/sand slurry mixture can be classified as a hazardous material, requiring proper disposal procedures.
7)Normal usage of the SURFACE GRINDER will allow the
