the motor slow down, and you will 

feel resistance from the work mate-

rial. 

Kick back can occur when making 

6. 

a plunge cut.

 When making a plunge 

cut, be extremely cautious to enter 

the work piece gradually, keeping the 

blade aligned with the line of the cut.

Kick back can be caused by hav-

7. 

ing a loose hold on the tool during 

operation.

 Always grip the tool firmly 

with both hands during operation.

Kick back can occur when cutting 

8. 

long pieces or large panels.

 As 

the cut progresses, the cut-off side 

can sag, causing it to bind the blade. 

When making long cuts, always 

support the cut-off piece to prevent 

it binding the blade. Using a clamp 

on the beginning of the kerf will help 

prevent the cut off from sagging.

Kick back can occur as internal 

9. 

stresses in a board are released 

during the cut. 

Green, wet, warped 

or improperly cured boards may twist 

and warp as they are cut. This warp-

ing can easily bind the blade causing 

kick back. Watch the cut-off piece as 

you work. If necessary, clamp the cut-

off piece or put a wedge in the kerf to 

prevent binding.

Kick back can be caused by using 

10. 

a dull, dirty or damaged blade.

 Al-

ways inspect your blade before use. 

Replace any blade that is dull, dirty 

or damaged. Good quality dull blades 

can be sharpened. Dirty blades can 

be cleaned with a blade cleaner to re-

move glue or pitch. Damaged blades 

should be discarded.

Kick back can be caused by using 

11. 

the wrong blade type for the work 

material.

 Always read the recom-

mendation of the blade manufacturer 

for the type of material and cut be-

ing made. Special blades are made 

for cross cutting, rip cutting, hard 

wood, plywood, soft wood, tile, ce-

ment board, demolition, various panel 

types, fiberglass, metal etc. Never 

use the wrong blade type for the job 

you are doing.

Kick back can occur at the end of a 

12. 

cut.

 Before completing the cut, sup-

port the waste piece to prevent it from 

falling or binding the blade as it is cut 

off. At the end of a cut release the 

Trigger (79) and allow the blade to 

stop turning before removing the saw 

from the cut.  

Kick back can occur if the Base 

13. 

Plate (103) is not properly adjusted 

or comes loose during the cut. 

Use 

the Base Plate to set the depth and 

bevel angle of the cut. After adjusting 

the Base Plate, secure the Cam Le-

vers (88) to prevent it from loosening.

Kick back can occur if you hit 

14. 

hidden obstacles.

 When making a 

plunge cut, into a wall for example, 

check to be sure you will not hit 

wires, pipes, conduit nails or other 

obstructions. Do not cut through nails 

or screws, these can damage the 

blade and may cause kick back.

If kick back occurs, immediately 

15. 

release the Trigger (79) and main

-

tain a firm grip on the tool as the 

blade stops turning.

 Do not restart 

the tool if the blade is binding. 

Unplug the tool to prevent acciden-

16. 

tal starting.
