8.Check Swing Guard (53) for proper closing before each use. Do not operate the Saw if the Swing Guard does not move freely and close instantly. Never clamp or tie the Swing Guard (53) into the open position. If the saw is acci- dently dropped, the Swing Guard (53) may be bent. Raise the Swing Guard (53) and make sure it moves freely and does not touch the Cut-Off Wheel or another part, in all depths of cut.

9.The Swing Guard (53) should be retracted manually only for special cuts such as “Pocket Cuts) and “Compound Cuts.” Raise the Swing Guard (53) only enough to begin the cut. As soon as the Cut-Off Wheel enters the material, the Swing Guard (53) must be released. For all other sawing, the Swing Guard (53) should be allowed to operate automatically.

10.The Saw is not to be used for any cutting in the locked down position. The Saw should be locked down position only for carrying and storage.

11.Always use Cut-Off Wheels with a 14” diameter, 1” arbor hole, and rated at a minimum of 3750 RPM. Cut-Off Wheels that do not match the mounting hard- ware of the Saw or that are rated at less than the Saw’s maximum RPM may fly off the Saw or may run eccentrically, causing loss of control.

12.Never use damaged or incorrect Cut-Off Wheel washers or bolts. The Cut- Off Wheel’s washers and bolts were specially designed for your Saw, for opti- mum performance and safety of operation.

13.Do not use the included Cut-Off Wheel to cut aluminum, copper, brass, or other non-ferrous metals. The included Cut-Off Wheel is designed to cut only ferrous (iron containing) metals such as steel alloys and cast iron. If using other Cut-Off Wheels, only use them on materials that the manufacturer recommends.

14.To avoid accidental injury, always wear heavy duty work gloves and work bib when changing a Cut-Off Wheel.

15.Before using the Cut-Off Saw, make sure the Cut-Off Wheel is properly mounted on the saw spindle. Make sure the Cut-Off Wheel is balanced and is not broken or bent.

16.Always unplug the Cut-Off Saw from its electrical outlet before perform- ing any inspection, maintenance, or cleaning procedures.
