To get maximum benefit from your tool and to ensure maximum safety, be sure to read this manual thoroughly. You should also periodically review safety instructions. Keep all manuals provided with your equipment in a safe place at all times. The information and specifications included in this publication were in effect at the time of approval for printing. U.S.SAWS reserves the right, however, to discontinue or change specifications or design at any time without notice and without incurring any obligation. The U.S.SAWS Core EZ Core® makes core drilling easy by utilizing standard 110 V power. U.S.SAWS Core EZ offers a new way of core drilling. The entire unit and a selection of bits fit into a wheeled case that weighs under 50 pounds. The Core EZ drills holes from 3 into 10 in with ease. The entire unit is mounted on a central guide shaft rigidly anchored to the wall that supports the weight of the tool during the drilling process. Having the system’s anchor in the middle of the hole eliminates damage to the wall. Read this entire operations and maintenance manual before using your new tool. Pay close attention to the Rules for safer operation,

DUST WARNING

Cutting, especially when DRY cutting, generates dust that comes from the material being cut, which frequently contains silica.
Silica is a basic component of sand, quartz, brick clay, granite and numerous other minerals and rocks. Exposure to excessive amount of such dust can cause:

• Respiratory diseases (affecting your ability to breath), including chronic bronchitis, silicosis and pulmonary fibrosis from exposure to silica. These diseases may be fatal;
• Skin irritation and rash; and
• Cancer according to NTP and IARC
• National Toxicology Program, International Agency for Research on Cancer

Take precautionary steps

• Avoid inhalation of and skin contact with dust, mist and fumes;
• Wet cut when feasible, to minimize dust;
• Wear and ensure that all bystanders wear appropriate respiratory protection such as dust masks designed to filter out microscopic particles. (See OSHA 29 CFR Part 1910.1200)California Prop 65 Warning: Use of this product can cause exposure to materials known to the State of California to cause cancer and/or birth defects or other reproductive harm.
