f

Never make warning signs on the machine 
unrecognisable. 

f

Never stand on the power tool. 

Serious inju-

ries can occur when the power tool tips over 
or when inadvertently coming into contact 
with the saw blade.

f

Operate the power tool only when the work 
area to the workpiece is clear of any adjust-
ing tools, wood chips, etc. 

Small pieces of 

wood or other objects that come in contact 
with the rotating saw blade can strike the op-
erator with high speed.

f

Operate the machine only for materials 
mentioned under “Intended Use”. 

Other-

wise, the machine can be subject to over-
load.

f

If the saw blade should become jammed or 
when interrupting work, switch the saw off 
and hold the workpiece until the saw blade 
comes to a complete stop. Never attempt to 
remove the workpiece as long as the saw 
blade is in motion, otherwise kickback may 
occur. 

Determine and correct the cause for 

the jamming of the saw blade.

f

Do not use dull, cracked, bent or damaged 
saw blades. 

Unsharpened or improperly set 

saw blades produce narrow kerf causing ex-
cessive friction, blade binding and kickback.

f

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

Saw blades that do not match the 

mounting hardware of the saw will run ec-
centrically, causing loss of control.

f

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

Such saw blades can easily break.

f

Do not touch the saw blade after working 
before it has cooled. 

The saw blade be-

comes very hot while working.

f

Do not direct the laser beam at persons or 
animals and do not stare into the laser 
beam yourself, not even from a distance. 

This power tool produces laser class 2 laser 
radiation according to EN 60825-1. This can 
lead to persons being blinded.

f

Do not allow children unsupervised use of 
the power tool with laser. 

They could blind 

other people.

f

Do not replace the installed laser with an-
other laser type. 

A laser that does not fit to 

this power tool could pose dangers for other 
persons.

Safety Warnings for Use as a Chop and Mitre 
Saw

f

Secure the workpiece. 

A workpiece clamped 

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

f

Make sure that the guard operates properly 
and that it can move freely. 

Never lock the 

guard in place when opened.

f

Keep hands away from the sawing area and 
the saw blade. 

Danger of injury when coming 

in contact with the saw blade.

f

Never remove cutting remainders, wood 
chips, etc. from the sawing area while the 
machine is running. 

Always guide the tool 

arm back to the neutral position first and 
then switch the machine off.

f

Guide the saw blade against the workpiece 
only when the machine is switched on. 

Oth-

erwise there is damage of kickback, when 
the saw blade becomes wedged in the work-
piece.

f

Always firmly clamp the piece to be 
worked. Do not saw workpieces that are too 
small to clamp. 

Otherwise, the clearance of 

your hand to the rotating saw blade is too 
small.

f

Never operate the machine without the in-
sert plate. Replace a defective insert plate. 

Without flawless insert plates, injuries are 
possible from the saw blade.

Safety Warnings for Use as a Table Saw

f

Make sure that the guard operates properly 
and that it can move freely. 

It must face 

against the table before sawing and against 
the workpiece while sawing; never lock the 
guard in place when opened.

f

Keep hands away from the sawing area and 
the saw blade. 

Danger of injury when coming 

in contact with the saw blade.
