5. 

Hold the power tool by insulated gripping 
surfaces only, when performing an operation 
where the cutting tool may contact hidden 
wiring or its own cord.

 Contact with a "live" wire 

will also make exposed metal parts of the power 
tool "live" and could give the operator an electric 
shock. 

6. 

When ripping, always use a rip fence or 
straight edge guide.

 This improves the accuracy 

of cut and reduces the chance of blade binding. 

7. 

Always use blades with correct size and shape 
(diamond versus round) of arbour holes.

Blades that do not match the mounting hardware 
of the saw will run eccentrically, causing loss of 
control. 

8. 

Never use damaged or incorrect blade 
washers or bolt.

 The blade washers and bolt 

were specially designed for your saw, for optimum 
performance and safety of operation. 

Kickback causes and related warnings 

−

  kickback is a sudden reaction to a pinched, bound 

or misaligned saw blade, causing an uncontrolled 
saw to lift up and out of the workpiece 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 toward the 
operator; 

−

  If the blade becomes twisted or misaligned in the 

cut, the teeth at the back edge of the blade can dig 
into the top surface of the workpiece causing the 
blade to climb out of the kerf and jump back toward 
the operator. 

Kickback is the result of saw misuse and/or incorrect 
operating procedures or conditions and can be avoided 
by taking proper precautions as given below. 

9. 

Maintain a firm grip with both hands on the 
saw and position your arms to resist kickback 
forces. Position your body to either side of the 
blade, but not in line with the blade.

 Kickback 

could cause the saw to jump backwards, but 

kickback forces can be controlled by the operator, 
if proper precautions are taken. 

10. 

When blade is binding, or when interrupting a 
cut for any reason, release the trigger and hold 
the saw motionless in the material until the 
blade comes to a complete stop. Never 
attempt to remove the saw from the work or 
pull the saw backward while the blade is in 
motion or kickback may occur.

 Investigate and 

take corrective actions to eliminate the cause of 
blade binding. 

11. 

When restarting a saw in the workpiece, centre 
the saw blade in the kerf and check that saw 
teeth are not engaged into the material.

 If saw 

blade is binding, it may walk up or kickback from 
the workpiece as the saw is restarted. 

12. 

Support large panels to minimise the risk of 
blade pinching and kickback.

 Large panels tend 

to sag under their own weight. Supports must be 
placed under the panel on both sides, near the 
line of cut and near the edge of the panel. 

To avoid kickback, do support 

board or panel near the cut.

000154 

Do not support board or 
panel away from the cut.

13. 

Do not use dull or damaged blades.

Unsharpened or improperly set blades produce 
narrow kerf causing excessive friction, blade 
binding and kickback. 

14. 

Blade depth and bevel adjusting locking levers 
must be tight and secure before making cut.

 If 

blade adjustment shifts while cutting, it may cause
