Be sure the trigger switch is in the OFF position. Do not make any adjustment while the wheel is in motion. Do not make any adjustment while chop saw is plugged into power supply. WARNING: Use only bonded reinforced cut-off wheels for your power tool. A bonded reinforced wheel is defined as a grinding wheel consisting of abrasive particles bonded together with various substances specifically for cutting steel materials. WARNING: Always use gloves when  handling wheels. WARNING: Handle and store all abrasive wheels carefully to prevent damage from thermal shock, heat, mechanical damage, etc. Store in a dry protected area free from high humidity, freezing temperatures or extreme temperature changes. WARNING: Do not impact the wheel, and do not use a wheel that has been dropped or impacted. Do not use a chipped, deformed or damaged wheel. 1.

Install the new abrasive wheel by reversing the above steps. 4. For safe operation, securely tighten bolt 19 to firmly secure the abrasive wheel 10 in between inner 18 and outer flanges 21 . Do not overtighten bolt 19 . WARNING: Check the work surface that the chop saw rests on when replacing with a new abrasive wheel. It is possible that the wheel may contact ANY ITEMS OR STRUCTURE THAT EXTENDS ABOVE work surface (under the base) when the arm is fully lowered. Operation Tips for More Accurate Cuts • Allow the wheel to do the cutting. Excessive force will cause the wheel to glaze reducing cutting efficiency and/or to deflect causing inaccurate cuts. • Properly adjust fence angle. • Make sure material is laying flat across base. • Properly clamp material to avoid movement and vibration.
