Further safety instructions for all saws

Causes and operator prevention of kickback:

–  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 wood 

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.

a) 

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.

b) 

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.

c) 

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.

d) 

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.

e) 

Do not use dull or damaged blades.

 Unsharpened or improperly 

set blades produce narrow kerf causing excessive friction, blade 

binding and kickback.

f) 

Blade depth and bevel adjusting locking levers must be tight 

and secure before making cut.

 If blade adjustment shifts while 

cutting, it may cause binding and kickback.

g) 

Use extra caution when making a „plunge cut“ into existing 

walls or other blind areas.

 The protruding blade may cut objects 

that can cause kickback.

Safety instructions for saws with lower 

quard

a) 

Check lower guard for proper closing before each use. Do not 

operate the saw if lower guard does not move freely and close 

instantly. Never clamp or tie the lower guard into the open 

position.

 If saw is accidentally dropped, lower guard may be 

bent. Raise the tower guard with the retracting handle and make 

sure it moves freely and does not touch the blade or any other 

part, in all angles and depths of cut.

b) 

Check the operation of the lower guard spring. If the guard 

and the spring are not operating properly, they must be 

serviced before use.

 Lower guard may operate sluggishly due to 

damaged parts, gummy deposits, or a build-up of debris.

c) 

Lower guard may be retracted manually only for special cuts 

such as „plunge cuts“ and „compound cuts.“ Raise lower guard 

by retracting handle and as soon as blade enters the material, 

the lower guard must be released.

 For all other sawing, the 

lower guard should operate automatically.

d) 

Always observe that the lower guard is covering the blade 

before placing saw down on bench or floor.

 An unprotected, 

coasting blade will cause the saw to walk backwards, cutting 

whatever is in its path. Be aware of the time it takes for the blade 

to stop after switch is released.

Additional safety instructions for all 

saws with riving knife

a) 

Use the appropriate riving knife for the blade being used.

 For 

the riving knife to work, it must be thicker than the body of the 

blade but thinner than the tooth set of the blade.

b) 

Adjust the riving knife as described in this instruction manual.

Incorrect spacing, positioning and alignment can make the 

riving knife ineffective in preventing kickback.

c) 

Always use the riving knife except when plunge cutting.

 Riving 

knife must be replaced after plunge cutting. Riving knife causes 

interference during plunge cutting and can create kickback.

d) 

For the riving knife to work, it must be engaged in the 

workpiece.

 The riving knife is ineffective in preventing kickback 

during short cuts.

e) 

Do not operate the saw if riving knife is bent.

 Even a light 

interference can slow the closing rate of a guard.
