Service



Have your power tool serviced by a qualified repair per-
son using only identical replacement parts. 

This will en-

sure that the safety of the power tool is maintained.

Safety Warnings for Circular Saws

Cutting procedures



DANGER: Keep hands away from cutting area and the 
blade. Keep your second hand on auxiliary handle, or 
motor housing. 

If both hands are holding the saw, they 

cannot be cut by the blade.



Do not reach underneath the workpiece. 

The guard can-

not protect you from the blade below the workpiece.



Adjust the cutting depth to the thickness of the work-
piece. 

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. Secure the workpiece to a stable platform. 

It is im-

portant to support the work properly to minimize body ex-
posure, blade binding, or loss of control.



Hold the power tool by insulated gripping surfaces on-
ly, 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.



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

This improves the accuracy of cut and reduces the 

chance of blade binding.



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

Blades that do not 

match the mounting hardware of the saw will run eccentri-
cally, causing loss of control.



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 opera-
tion.



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 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 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.

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.
