GENERAL SAFETY RULES
1) Work area
a) Keep work area clean and well lit. Cluttered and dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools create sparks, which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool. Distractions can cause
you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any way. Do
not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk of electric shock if your body is grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.

d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power
tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled
cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension cord suitable for
outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
3) Personal safety
a) Stay alert, watch what you are doing and use common sense when operating a
power tool. Do not use a power tool while you are tired or under the influence of
drugs, alcohol or medication. A moment of inattention while operating power tools may
result in serious personal injury
b) Use safety equipment. Always wear eye protection. Safety equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce
personal injuries
c) Avoid accidental starting. Ensure the switch is in the off-position before plugging in.
Carrying power tools with your finger on the switch or plugging in power tools that have the switch
on invite accidents.
d) Remove any adjusting key or wrench before turning the power tool on.
A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This enables
better control of the power tool in unexpected situations
f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and
gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving
parts.
g) If devices are available in your shop for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of these devices can
reduce dust related hazards.
4) Power tool use and care
a) Secure work. Use a clamp, vise or other practical means to hold your work securely, freeing
both hands to control the tool.
b) Do not force the power tool. Use the correct power tool for your application. The correct
power tool will do the job better and safer at the rate for which it was designed
c) Do not use the power tool If the switch does not turn It on and off. Any power tool that
cannot be controlled with the switch is dangerous and must be repaired.
d) Disconnect the plug from the power source and/or the battery pack from the
power tool before making any adjustments, changing accessories, or storing power
tools. Such preventive safety measures reduce the risk of starting the power tool accidentally,
e) Store idle power tools out of reach of children and do not allow persons unfamiliar with
the power tool or these Instructions to operate the power tool. Power tools are dangerous in
the hands of untrained users.
f) Maintain power tools. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tools operation. If
damaged, have the power tool repaired before use. Many accidents are caused by
poorly maintained power tools.
g) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.

Into account the working conditions and the work to be performed. Use of the power
tool for operations different from those intended could result in a hazardous situation.
5) Service
a) Have your power tool serviced by a qualified repair person using only Identical
replacement parts. This will ensure that the safety of the power tool is maintained.
WARNING: RECOMMENDED FOR USE WITH A
GFCI WITH A RATED RESIDUAL CURRENT OF 30 mA OR LESS.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush
or any other accessory. Pinching or snagging causes rapid stalling of the rotating accessory which
in turn causes the uncontrolled power tool to be forced in the direction opposite of the accessory's
rotation at the point of the binding.
For example, if an abrasive wheel is snagged or pinched by he work piece. 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 jump either 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.
Kickback is the result of power tool misuse and/or incorrect operating procedures or
conditions and can be avoided by taking proper precautions as given below.
a) Maintain a firm grip on the power tool and position your body and arm to allow you to
resist kickback forces. Always use auxiliary handle, if provided, for maximum control over
kickback or torque reaction during start-up.
The operator can control torque reactions or kickback forces, if proper precautions are
taken.
b) Never place your hand near the rotating accessory
Accessory may kickback over your hand.
c) Do not position your body in the area where power tool will move if kickback occurs.
Kickback will propel the tool in direction opposite to the wheel’s movement at the point of snagging.
d) Use special care when working corners, sharp edges etc. Avoid bouncing and
snagging the accessory.
Corners, sharp edges or bouncing have a tendency to snag the rotating accessory and
cause loss of control or kickback
e) Do not attach a Saw chain woodcarving blade or toothed saw blade.
Such blades create frequent kickback and loss of control

IMPORTANT SAFETY CONSIDERATIONS
WARNING! Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• lead from lead-based paint
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed to filter out microscopic particles.
Wheel Instructions
1. Use only the edge (not the sides) of the wheel for cutting. Do not allow the wheel to twist or bind.
2. Keep hands and body away from the rotating wheel. Do not wear loose clothing when using this
tool.
3. Store cut-off wheels with care. Do not drop them or subject them to excessive heat, cold or
humidity.
4. Make sure that all wheel flanges and other mounting hardware are in good condition and are
always used properly. Defective or missing parts may cause damage to the wheel. Always use
mounting flanges supplied with the tool.
5. Cutting with a damaged wheel is very hazardous. After installing a new wheel, leave the tool
unplugged and rotate the wheel by hand to see if it is uneven, warped, or cracked. If so, discard the
wheel and replace it with a new one. Do not use a wheel that has been dropped; impact may result
in breakage.
6. Before starting a cut, step out of line of the wheel and make a trial run to confirm that the wheel is
in good condition. Trial run periods are:
When replacing a cut-off wheel — over 3 minutes.
When starting routine work — over 1 minute.
7. Never try to remove or clamp the workpiece to the tool while the cutoff wheel is rotating.
8. Before installing a cut-off wheel, always inspect it for cracks. Replace cracked wheel immediately.
9. Always check maximum operating speed established for wheel against machine speed. Do not
exceed the maximum operating speed that is marked on the wheel.

nut in clockwise direction.
2. To reduce the depth of cut, rotate the hexagonal nut in counterclockwise direction, then tighten
the hexagon bolt (clockwise).
Support the workpiece and adjust the work vise:
The work vise is located on the base of the Cut-off Saw.
The vise is made up of two parts: (fig. 8)
(1) a quick adjust fence which can be loosened and rotated from -45° to 45°.
(2) a movable clamp with an adjustable pivoting handle and a quick lock/ release lever.
When adjusting, the clamp and fence should be positioned so
the centerline of the wheel hub is in line with or behind the
centerline of the workpiece, toward the rear of the tool (fig. 9).
The workpiece should be resting flush with the base of the
cut-off machine.
