Removal and Installation of Wheels
(Fig. G, H)

WARNING: Turn off and unplug the tool before
making any adjustments or removing or
installing attachments or accessories. 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.

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.
