GENERAL SAFETY RULES
(For All Tools)

WARNING! Read and understand all instructions.

Failure to follow all instructions listed below, may result
in electric shock, fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS.

Work Area

1. Keep your work area clean and well lit.

Cluttered benches and dark areas invite
accidents.

2. 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.

3. Keep bystanders, children, and visitors away
while operating a power tool. Distractions can
cause you to lose control.

Electrical Safety

4. Double insulated tools are equipped with a
polarized plug ( one blade is wider than the
other.) This plug will fit in a polarized outlet
only one way. If the plug does not fit fully in
the outlet, reverse the plug. If it still does not
fit, contact a qualified electrician to install a
polarized outlet. Do not change the plug in any
way. Double insulation

the three wire grounded power cord and grounded
power supply system.

5. Avoid body contact with grounded surfaces

such as pipes, radiators, ranges and
refrigerators. There is an increased risk of

electric shock if your body is grounded.

6. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.

7. Do not abuse the cord. Never use the cord to

carry the tools or pull the plug from an outlet.

Net weight 12.0 kg (26.5 lbs)

eliminates the need for

Keep cord away from heat, oil, sharp edges or
moving parts. Replace damaged cords
immediately. Damaged cords increase the risk of

electric shock.

8. When operating a power tool outside, use an
outdoor extension cord marked "W-A" or "W".
These cords are rated for outdoor use and reduce
the risk of electric shock.

Personal Safety

9. Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use tool while tired or under the
influence of drugs, alcohol, or medication. A

moment of inattention while operating power tools
may result in serious personal injury.

10. Dress properly. Do not wear loose clothing or

jewelry. Contain long hair. Keep your hair,
clothing, and gloves away from moving parts.

Loose clothes, jewelry, or long hair can be caught
in moving parts.

11. Avoid accidental starting. Be sure switch is off
before plugging in. Carrying tools with your
finger on the switch or plugging in tools that have
the switch on invites accidents.

12. Remove adjusting keys or wrenches before
turning the tool on. A wrench or a key that is left
attached to a rotating part of the tool may result in
personal injury.

13. Do not overreach. Keep proper footing and
balance at all times. Proper footing and balance
enables better control of the tool in unexpected
situations.

14. Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety shoes,
hard hat, or hearing protection must be used for
appropriate conditions. Ordinary eye or sun
glasses are NOT eye protection.

Tool Use and Care

15. Use clamps or other practical way to secure
and support the workpiece to a stable platform.

Holding the work by hand or against your body is

2

unstable and may lead to loss of control.

16. Do not force tool. Use the correct tool for your
application. The correct tool will do the job better
and safer at the rate for which it is designed.

17. Do not use tool if switch does not turn it on or
off. Any tool that cannot be controlled with the
switch is dangerous and must be repaired.

18. Disconnect the plug from the power source

before making any adjustments, changing
accessories, or storing the tool. Such

preventive safety measures reduce the risk of
starting the tool accidentally.

19. Store idle tools out of reach of children and
other untrained persons. Tools are dangerous in
the hands of untrained users.

20. Maintain tools with care. Keep cutting tools
sharp and clean. Properly maintained tools with
sharp cutting edges are less likely to bind and are
easier to control.

21. Check for misalignment or binding of moving

parts, breakage of parts, and any other
condition that may affect the tool’s operation.
If damaged, have the tool serviced before
using. Many accidents are caused by poorly

maintained tools.

22. Use only accessories that are recommended

by the manufacturer for your model.
Accessories that may be suitable for one tool,
may become hazardous when used on another
tool.

Service

23. Tool service must be performed only by
qualified repair personnel. Service or

maintenance performed by unqualified personnel
could result in a risk of injury.

24. When servicing a tool, use only identical

replacement parts. Follow instructions in the
Maintenance section of this manual. Use of

unauthorized parts or failure to follow
Maintenance instructions may create a risk of
electric shock or injury.

USE PROPER EXTENSION CORD. Make sure your
extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to
carry the current your product will draw. An
undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. Table 1
shows the correct size to use depending on cord
length and nameplate ampere rating. If in doubt, use
the next heavier gage. The smaller the gage number,
the heavier the cord.

SPECIFIC SAFETY RULES

DO NOT let comfort or familiarity with product (gained
from repeated use) replace strict adherence to cutter
safety rules. If you use this tool unsafely or incorrectly,
you can suffer serious personal injury.

1. Always use proper guard with wheel. A guard

Wheels and other accessories running over rated
speed can fly apart and cause injury.

performing an operation where the cutting tool
may contact hidden wiring or its own cord.

Contact with a "live" wire will make exposed metal

parts of the tool "live" and shock the operator.

4. Always use safety glasses or goggles.

Ordinary eye or sun glasses are NOT safety
glasses.

5. Check the wheel carefully for cracks or
damage before operation. Replace cracked or
damaged wheel immediately. Run the tool
(with guard) at no load for about a minute,
holding tool away from others. If wheel is
flawed, it will likely separate during this test.

6. Use only flanges specified for this tool.

7. Be careful not to damage the spindle or the

flange (especially the installing surface).
Damage to these parts could result in wheel
breakage.

8. NEVER use tool with wood cutting blades or
other sawblades. Such blades when used on a

3

Not Recommended

grinder frequently kick and cause loss of
control leading to personal injury.

9. Hold the tool firmly.

10. Keep hands away from rotating parts.

11. Make sure cord is clear of wheel. Do not wrap

cord around your arm or wrist. If control of
tool is lost, cord may become wrapped around
you and cause personal injury.

12. Make sure the wheel is not contacting the
workpiece before the switch is turned on.

13. Before using the tool on an actual workpiece,
let it run for a while. Watch for vibration or
wobbling that could indicate poor installation
or a poorly balanced wheel.

14. Watch out for flying sparks. Hold the tool so
that sparks fly away from you and other
persons or flammable materials.

15. Do not leave the tool running. Operate the tool
only when hand-held.

16. Do not touch the workpiece immediately after
operation; it may be extremely hot and could
burn your skin.

17. ALWAYS wear proper apparel including long
sleeve shirts, leather gloves and shop aprons
to protect skin from contact with hot cuttings.

18. Use of this tool to cut some products could
expose user to dust containing hazardous
substances. Use appropriate respiratory
protection.

19. The tool must be used only for dry cutting. DO
NOT use water.

OPERATION

CAUTION:

Be sure to pull the tool when cutting a workpiece.

• Use this tool for straight line cutting only. Cutting

curves can cause stress cracks or fragmentation of
the diamond wheel and abrasive cut-off wheel
resulting in possible injury to persons in the vicinity.

• After operation, always switch off the tool and wait

until the wheel has come to a complete stop before
putting the tool down.

• When cutting concrete blocks, tiles or masonry

materials, do not make a cut in depth more than 60
mm (2-3/8"). When you need to cut a workpiece
over 60 mm (2-3/8") up to 100 mm (4"), make more
than two passes of cuts. The depth of the most

efficient cut is about 40 mm (1-9/16").
Hold the tool firmly with both hands. First keep the wheel
without making any contact with a workpiece to be cut.
Then turn the tool on and wait until the wheel attains full
speed.
