GUARD FUNCTION

■

Check the guard for proper closing before each 
use. Do not operate the saw if guard does not move 
freely and enclose the blade instantly. Never clamp 
or tie the guard so that the blade is exposed.

 If saw 

is accidentally dropped, guard may be bent. Check to 
make sure that guard moves freely and does not touch 
the blade or any other part, in all angles and depths 
of cut.

■

Check the operation and condition of the guard 
return spring. If the guard and the spring are not 
operating properly, they must be serviced before 
use.

 Guard may operate sluggishly due to damaged 

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

■

Assure that the base plate of the saw will not shift 
while performing the “plunge cut”.

 Blade shifting 

sideways will cause binding and likely kick back.

■

Always observe that the 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.

SAFETY INSTRUCTIONS FOR ABRASIVE 
CUTTING-OFF OPERATIONS

CUT-OFF MACHINE SAFETY WARNINGS

■

The guard provided with the tool must be securely 
attached to the power tool and positioned for 
maximum safety, so the least amount of wheel is 
exposed towards the operator. Position yourself 
and bystanders away from the plane of the rotating 
wheel.

 The guard helps to protect operator from broken 

wheel fragments and accidental contact with wheel.

■

Use only diamond cut-off wheels for your power 
tool.

 Just because an accessory can be attached to 

your power tool, it does not assure safe operation.

■

The rated speed of the accessory must be at least 
equal to the maximum speed marked on the power 
tool.

 Accessories running faster than their rated speed 

can break and fly apart.

■

Wheels must be used only for recommended 
applications. For example, do not grind with the 
side of cut-off wheel.

 Abrasive cut-off wheels are 

intended for peripheral grinding. Side forces applied to 
these wheels may cause them to shatter.

■

Always use undamaged wheel flanges that are of 
correct diameter for your selected wheel.

 Proper 

wheel flanges support the wheel, thus reducing the 
possibility of wheel breakage.

■

The outside diameter and the thickness of your 
accessory must be within the capacity rating of 
your power tool.

 Incorrectly sized accessories cannot 

be adequately guarded or controlled.

■

The arbour size of wheels and flanges must properly 
fit the spindle of the power tool.

 Wheels and flanges 

with arbour holes that do not match the mounting 
hardware of the power tool will run out of balance, 
vibrate excessively and may cause loss of control.

■

Do not use damaged wheels. Before each use, 
inspect the wheels for chips and cracks. If power 
tool or wheel is dropped, inspect for damage or 
install an undamaged wheel. After inspecting 
and installing the wheel, position yourself and 
bystanders away from the plane of the rotating 
wheel and run the power tool at maximum no load 
speed for one minute.

 Damaged wheels will normally 

break apart during this test time.

■

Wear personal protective equipment. Depending 
on application, use face shield, safety goggles or 
safety glasses. As appropriate, wear dust mask, 
hearing protectors, gloves and shop apron capable 
of stopping small abrasive or workpiece fragments.

The eye protection must be capable of stopping flying 
debris generated by various operations. The dust mask 
or respirator must be capable of filtrating particles 
generated by the operation. Prolonged exposure to 
high intensity noise may cause hearing loss.

■

Keep bystanders a safe distance away from work 
area. Anyone entering the work area must wear 
personal protective equipment.

 Fragments of 

workpiece or of a broken wheel may fly away and cause 
injury beyond immediate area of operation.

■

Hold the power tool by insulated gripping surfaces 
only, when performing an operation where the 
cutting accessory may contact hidden wiring.

Cutting accessory contacting a “live” wire may make 
exposed metal parts of the power tool “live” and could 
give the operator an electric shock.

■

Never lay the power tool down until the accessory 
has come to a complete stop.

 The spinning wheel 

may grab the surface and pull the power tool out of your 
control.

■

Do not run the power tool while carrying it at your 
side.

 Accidental contact with the spinning accessory 

could snag your clothing, pulling the accessory into 
your body.

■

Regularly clean the power tool’s air vents.

 The 

motor’s fan will draw the dust inside the housing and 
excessive accumulation of powdered metal may cause 
electrical hazards.

■

Do not operate the power tool near flammable 
materials.

 Sparks could ignite these materials.

■

Do not use accessories that require liquid coolants. 

Using water or other liquid coolants may result in 
electrocution or shock.

KICKBACK AND RELATED WARNINGS

Kickback is a sudden reaction to a pinched or snagged 
rotating wheel. Pinching or snagging causes rapid stalling 
of the rotating wheel which in turn causes the uncontrolled 
power tool to be forced in the direction opposite of the 
wheel’s rotation at the point of the binding.
For example, if an abrasive wheel is snagged or pinched 
by the workpiece, the edge of the wheel that is entering 
into the pinch point can dig into the surface of the material 
causing the wheel to climb out or kick out. The wheel may 
either jump toward or away from the operator, depending on 
direction of the wheel’s movement at the point of pinching. 
Abrasive wheels may also break under these conditions.
