GENERAL SAFETY PRECAUTIONS

(For All Tools)

1.

KNOW YOUR POWER TOOL. Read the
owner’s manual carefully. Learn the tool’s
applications and limitations, as well as the
specific potential hazards peculiar to it.

2.

KEEP GUARDS IN PLACE and in working
order.

3.

REMOVE ADJUSTING KEYS AND
WRENCHES. Form habit of checking to
see that keys and adjusting wrenches are
removed from tool before turning it on.

4.

KEEP WORK AREA CLEAN. Cluttered
areas and benches invite accidents.

5.

DON’T USE IN DANGEROUS ENVIRON­MENT. Don’t use power tools in damp or
wet locations, or expose them to rain.
Keep work area well lighted. Don’t use
tool in presence of flammable liquids or
gases.

2

6.

KEEP CHILDREN AWAY. All visitors
should be kept safe distance from work
area.

7.

MAKE WORKSHOP KID PROOF with pad­locks, master switches, or by removing
starter keys.

8.

DON’T FORCE TOOL. It will do the job bet­ter and safer at the rate for which it was
designed.

9.

USE RIGHT TOOL. Don’t force tool or
attachment to do a job for which it was not
designed.

10.

WEAR PROPER APPAREL. Do not wear
loose clothing, gloves, neckties, rings,
bracelets, or other jewelry which may get
caught in moving parts. Nonslip footwear
is recommended. Wear protective hair
covering to contain long hair.

USA007-1

11.

ALWAYS USE SAFETY GLASSES. Also
use face or dust mask if cutting operation
is dusty. Everyday eyeglasses only have
impact resistant lenses, they are NOT
safety glasses.

12.

SECURE WORK. Use clamps or a vise to
hold work when practical. It’s safer than
using your hand and it frees both hands
to operate tool.

13.

DON’T OVERREACH. Keep proper footing
and balance at all times.

14.

MAINTAIN TOOLS WITH CARE. Keep tools
sharp and clean for best and safest perfor­mance. Follow instructions for lubricating
and changing accessories.

15.

DISCONNECT TOOLS before servicing;
when changing accessories such as
blades, bits, cutters, and the like.

16.

REDUCE THE RISK OF UNINTENTIONAL
STARTING. Make sure switch is in off
position before plugging in.

17.

USE RECOMMENDED ACCESSORIES.
Consult the owner’s manual for recom­mended accessories. The use of improper
accessories may cause risk of injury to
persons.

18.

NEVER STAND ON TOOL. Serious injury
could occur if the tool is tipped or if the
cutting tool is unintentionally contacted.

19.

CHECK DAMAGED PARTS. Before further
use of the tool, a guard or other part that
is damaged should be carefully checked
to determine that it will operate properly
and perform its intended function - check
for alignment of moving parts, binding of
moving parts, breakage of parts, mount­ing, and any other conditions that may
affect its operation. A guard or other part
that is damaged should be properly
repaired or replaced.

20.

DIRECTION OF FEED. Feed work into a
blade or cutter against the direction of
rotation of the blade or cutter only.

21.

NEVER LEAVE TOOL RUNNING UNAT­TENDED. TURN POWER OFF. Don’t leave
tool until it comes to a complete stop.

22.

REPLACEMENT PARTS. When servicing
use only identical replacement parts.

23.

POLARIZED PLUGS. To reduce the risk of
electric shock, this equipment has 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 the proper outlet. Do not
change the plug in any way.

VOLTAGE WARNING: Before connecting the tool to a power source (receptacle, outlet,

etc.) be sure the voltage supplied is the same as that specified on the nameplate of the tool.
A power source with voltage greater than that specified for the tool can result in SERIOUS
INJURY to the user - as well as damage to the tool. If in doubt, DO NOT PLUG IN THE
TOOL. Using a power source with voltage less than the nameplate rating is harmful to the
motor.

3

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

USB078-1

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

1.

Wear hearing protection during extended
periods of operation.

2.

Use only wheels having a maximum oper­ating speed at least as high as “No Load
RPM” marked on the tool’s nameplate.
Use only fiberglass-reinforced cut-off
wheels.

3.

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, keeping tool away from
others. If wheel is flawed, it will likely sep­arate during this test.

4.

Secure the wheel carefully.

5.

Use only flanges specified for this tool.

6.

Be careful not to damage the spindle, the
flange (especially the installing surface)
or the bolt. Damage to these parts could
result in wheel breakage.

7.

Do not operate the tool without guards in
place. Check wheel guard for proper clos­ing before each use. Do not operate the
tool if wheel guard does not move freely
and close instantly. Never clamp or tie the
wheel guard into the open position.

8.

Hold the handle firmly.

9.

Keep hands away from rotating parts.

10.

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

4

11.

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.

12.

Watch out for flying sparks when operat­ing. They can cause injury or ignite com­bustible materials.

13.

Remove material debris from the area that
might be ignited by sparks. Be sure that
others are not in the path of the sparks.
Keep a proper , charged extinguisher
closely available.

14.

Use the cutting edge of the wheel only.
Never use side surface.

15.

Do not attempt to keep the trigger in the
ON position.

16.

If the wheel stops during operation,
makes an odd noise or begins to vibrate,
switch off the tool immediately.

17.

Turn off the tool and wait for the wheel to
stop before moving workpiece or chang­ing settings.

18.

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

19.

Store wheels in a dry location only.

When the cut-off wheel has worn down considerably, use a
spacer block of sturdy, non-flammable material behind the
workpiece as shown in the figure. You can more efficiently
utilize the worn wheel by using the mid point on the periphery
of the wheel to cut the workpiece.

When cutting workpieces over 65 mm (2-9/16”) wide at an
angle, attach a straight piece of wood (spacer) over 190 mm
(7-1/2”) long x 45 mm (1-3/4”) wide to the guide plate as
shown in the figure. Attach this spacer with screws through
the holes in the guide plate.

If you use a spacer block which is slightly narrower than the
workpiece as shown in the figure, you can also utilize the
wheel economically.

Hold the handle firmly. Switch on the tool and wait until the
wheel attains full speed before lowering gently into the cut.
When the wheel contacts the workpiece, gradually bear
down on the handle to perform the cut. When the cut is com­pleted, switch off the tool and WAIT UNTIL THE WHEEL
HAS COME TO A COMPLETE STOP before returning the
handle to the fully elevated position.

CAUTION:

• Proper handle pressure during cutting and maximum
cutting efficiency can be determined by the amount of
sparks that is produced while cutting. Your pressure on
the handle should be adjusted to produce the maximum
amount of sparks. Do not force the cut by applying
excessive pressure on the handle. Reduced cutting
efficiency, premature wheel wear, as well as, possible
damage to the tool, cut-off wheel or workpiece may
result.
