Note: This document does not provide
information about how to operate this machine. It only lists
potential hazards associated with using the machine and safety
practices. Before using the machine be sure to receive proper
instruction on it's use.
Potential hazards: Because of the rapid
spinning motion of the sharp circular saw blade, the following
hazards exist.
Any body contact with the moving blade will cause severe injury.
Clothing or other articles that contact the moving blade could become
entangled and pull the operator into the blade.
The work piece can be thrown (kicked back) violently from the
rotating saw blade.
Small pieces of the work piece and saw dust can be thrown out at the
operator.
The operator could slip and fall into the saw.
Safety practices: Because of those potential hazards
the following safety rules must be followed.
Be sure to perform only operations you know how to do safely.
Always wear safety glasses
Never wear cloths or other articles that dangle and could catch on
the saw
Be sure to have firm footing
Check the saw to make sure it is in good working order.
Make all adjustments with the saw turned off, and unplugged in cases
where the blade is or could be touched.
Use an appropriate saw blade guard when possible. (most operations
can be done with the guard), check with the instructor before making
any cuts without the guard
Adjust the blade to 1/8 to 1/4 inch above the top of the stock.
Never make “free hand” cuts on the circular saw, always use
the fence, miter gage or other fixture.
Never stand directly behind the saw blade.
When using the miter gage be sure it slides freely and clears the
blade
Do not reach directly over the moving blade to remove stock
Use a push stick or handle for narrow work
Never clear scraps away from the operating blade with your
fingers
Always use a clearance block when cross cutting duplicate parts (do
not use the fence and miter gage in direct combination), the stock
can bind and kick back
Have someone help support long stock, but don’t allow them to
pull the stock
Avoid distractions, never look away during a cut
Do not allow others to crowd around the saw
Turn the saw off immediately if it does not sound right or if slivers
of wood catch between the blade and table
Always push the work well beyond the blade when finishing a cut
Never let go of the stock during the cut
Do not saw stock that rocks on the table or that does not track
straight along the fence
