2. Inspect the tool carefully to make sure that no 
breakage or damage occurred during shipping.
3. Do not discard the packing material until you 
have carefully inspected and satisfactorily oper-
ated the tool.
4. If any parts are damaged or missing, return 
the product for replacement.

 WARNING: If any parts are broken or miss-

ing, DO NOT attempt to plug in the power cord 
or operate the saw until the broken or missing 
parts are replaced. Failure to do so could result 
in possibly serious injury.

 WARNING: Do not attempt to modify this 

saw or create accessories not recommended for 
use with this saw. Any such alteration or modifi-
cation is misuse and could result in a hazardous 
condition leading to possibly serious injury.

 WARNING: To prevent accidental starting 

that could cause serious personal injury, always 
disconnect the tool from the power source 
when assembling parts.

OPERATION INSTRUCTIONS

 WARNING: The maximum blade capacity of 

your saw is 7-1/4 inches. Any blade larger than 
7-1/4 inch will come in contact with the blade 
guards. Never use a blade that is so thick that it 
prevents the outer blade washer from engaging 
with the flat side of the spindle. Blades that are 
too large or too thick can result in an accident 
causing serious injury.

SAW BLADES
All saw blades need to be kept clean, sharp, 
and properly set in order to cut efficiently. Us-
ing a dull blade places a heavy load on the saw 
and increases the danger of kickback. Keep ex-
tra blades on hand, so sharp blades are always 
available. 
Gum and wood pitch that have hardened on the 
blade will slow the saw. Use gum and pitch re-
mover, hot water, or kerosene to remove these 
substances. Do not use gasoline.

BLADE GUARD SYSTEM
The lower blade guard is there for your protec-
tion and safety. It should never be altered for 
any reason. If the lower blade guard becomes 
damaged or begins to return slowly or slug-
gishly, do not operate your saw until the dam-
aged part has been repaired or replaced. Always 
leave the guard in its correct operating position 
when using the saw. 

 CAUTION: Never use the saw when the 

lower blade guard is not operating properly. 
The lower blade guard should be checked for 
correct operation before each use. If you drop 
your saw, check the lower blade guard and 
bumper for damage at all depth settings before 
using. 

NOTE: The lower blade guard is operating prop-
erly when it moves freely and then readily re-
turns to the closed position. If, for any reason, 
your lower blade guard and bumper do not 
close freely, take the saw to your nearest Service 
Center for service before using it.  

KICKBACK

KICKBACK CAUSES
• Kickback is a sudden reaction to a pinched, 
bound, or misaligned saw blade, which can 
cause the saw to lift up and out of the work-
piece and toward the operator.
• When the blade is pinched or bound tightly 
by the kerf closing down, the blade stalls and 
the motor reaction drives the unit rapidly back 
towards the operator.
• If the blade becomes twisted or misaligned in 
the cut, the teeth at the rear edge of the blade 
can dig into the top surface of the wood. 
This causes the blade to climb out of the kerf 
and jump back towards the operator.
• Sawing into knots or nails in the workpiece 
can cause kickback.
• Sawing into wet or warped lumber can cause 
kickback.
• Forcing a cut, or not supporting the workpiece 
correctly can cause kickback.
• Kickback can result from tool misuse and/or in-
correct operating procedures or conditions.

HOW TO PREVENT KICKBACK

 DANGER: Always release the trigger switch 

immediately if the blade binds or the saw stalls. 
Kickback could cause you to lose control of the 
saw. Loss of control can lead to serious injury.

Lower Blade Guard level 

is in UP position when 

making a cut.

Lower Blade Guard 

retracts automatically 

when cut is being  

made.

1/4” or less of the Blade is 

exposed on the underside 

of the  workpiece.
