Kickback is the result of saw misuse and/or incorrect oper-
ating procedures or conditions and can be avoided by tak-
ing proper precautions as given below.



Maintain a firm grip with both hands on the saw and po-
sition 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 back-

wards, but kickback forces can be controlled by the opera-
tor, if proper precautions are taken.



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

Investigate and take correc-

tive actions to eliminate the cause of blade binding.



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

If saw blade is binding, it may 

walk up or kickback from the workpiece as the saw is re-
started.



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 pan-
el on both sides, near the line of cut and near the edge of 
the panel.



Do not use dull or damaged blades. 

Unsharpened or im-

properly set blades produce narrow kerf causing excessive 
friction, blade binding and kickback.



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.



Use extra caution when sawing into existing walls or 
other blind areas. 

The protruding blade may cut objects 

that can cause kickback.

Lower guard function



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 lower 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.



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.



The lower guard may be retracted manually only for 
special cuts such as “plunge cuts and angle cuts”. Raise 
the lower guard by retracting the handle and as soon as 
the blade enters the material, release the lower guard. 

For all other sawing operations, the lower guard should op-
erate automatically.



Always observe that the lower guard is covering the 
blade before placing saw down on bench or floor. 

An un-

protected, coasting blade will cause the saw to walk back-
wards, cutting whatever is in its path. Be aware of the time 
it takes for the blade to stop after switch is released.

Riving knife function (GKS 85 G)



Use the appropriate saw blade for the riving knife. 

For 

the riving knife to function, the body of the blade must be 
thinner than the riving knife and the cutting width of the 
balde must be wider than the thickness of the riving knife.



Adjust the riving knife as described in this instruction 
manual. 

Incorrect spacing, positioning and alignment can 

make the riving knife ineffective in preventing kickback.



Always use the riving knife except when plunge cut-
ting. 

Riving knife must be replaced after plunge cutting. 

Riving knife causes interference during plunge cutting and 
can create kickback.



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

The riving knife is ineffective in preventing 

kickback during short cuts.



Do not operate the saw if riving knife is bent. 

Even a 

light interference can slow the closing rate of a guard.

Additional safety warnings



Do not reach into the chip ejector with your hands. 

They 

could be injured by rotating parts.



Do not work overhead with the saw. 

In this manner you 

do not have sufficient control over the power tool.



Use suitable detectors to determine if utility lines are 
hidden in the work area or call the local utility company 
for assistance. 

Contact with electric lines can lead to fire 

and electric shock. Damaging a gas line can lead to explo-
sion. Penetrating a water line causes property damage or 
may cause an electric shock.



Do not operate the power tool stationary. 

It is not de-

signed for operation with a saw table.



Do not use high speed steel (HSS) saw blades. 

Such saw 

blades can easily break.



Do not saw ferrous metals. 

Red hot chips can ignite the 

dust extraction.



When working with the machine, always hold it firmly 
with both hands and provide for a secure stance. 

The 

power tool is guided more secure with both hands.



Secure the workpiece. 

A workpiece clamped with clamp-

ing devices or in a vice is held more secure than by hand.



Always wait until the machine has come to a complete 
stop before placing it down. 

The tool insert can jam and 

lead to loss of control over the power tool.
