INTENDED USE

This tool is intended for lengthways and crossways cutting of 
wood with straight cuts as well as angle cuts to 45°; with the 
appropriate saw blades also non-ferrous metals, light build-
ing materials and plastics can be cut

SAFETY

WARNING!  Read all instructions. Failure to follow all in-
structions listed below may result in electric shock, 

fi

 re 

and/or serious injury. 

DANGER

•  Keep hands away from cutting area and the blade; 
keep your second hand on front handle 

(if both hands 

are holding the saw, they can not be cut by the blade)

•  Do not reach underneath the workpiece 

(the guard 

cannot protect you from the blade below the workpiece)

•  Adjust the cutting depth to the thickness of the 
workpiece 

(less than a full tooth of the blade teeth should 

be visible below the workpiece)

•  Never hold piece being cut in your hands or across 
your leg 

(it is important to support the work properly 

to minimize body exposure, blade binding, or loss of 
control)

•  Hold tool by insulated gripping surfaces 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 tool 
“live” and shock the operator)

•  When ripping always use a rip fence or straight edge 
guide 

(this improves the accuracy of cut and reduces the 

chance for blade binding)

•  Always use blades with correct size and shape 
of arbor holes (diamond or round) 

(blades that do 

not match the mounting hardware of the saw will run 
eccentrically, causing loss of control)

•  Never use damaged or incorrect blade washers or 
bolts 

(the blade washers and bolt were specially designed 

for your saw, for optimum performance and safety of 
operation)

KICKBACK-CAUSES

•  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 towards operator

KICKBACK - OPERATOR PREVENTION 

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

• Maintain 

a 

fi

  rm 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)

•  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 backwards while the blade is 
in motion or kickback may occur 

(investigate and take 

corrective actions to eliminate the cause of blade binding; 
avoid cutting nails or screws)

•  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)

•  Support large panels to minimize 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)

•  Do not use a dull or damaged blade 

(unsharpened 

or improperly 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 making a plunge cut into 
existing walls or other blind areas 

(the protruding blade 

may cut objects that can cause kickback)

WARNING

•  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
