WARNING:  
For your personal safety, READ and UNDERSTAND before using.  
SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE.

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.  
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, mount-  
ing, and any other conditions that may  
affect its operation. A guard or other part  
that is damaged should be properly  
repaired or replaced.  
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.  
20. DIRECTION OF FEED. Feed work into a  
blade or cutter against the direction of  
rotation of the blade or cutter only.  
14. MAINTAIN TOOLS WITH CARE. Keep tools  
sharp and clean for best and safest perfor-  
mance. Follow instructions for lubricating  
and changing accessories.  
21. NEVER LEAVE TOOL RUNNING UNAT-  
TENDED. TURN POWER OFF. Don’t leave  
tool until it comes to a complete stop.  
15. DISCONNECT TOOLS before servicing;  
when changing accessories such as  
blades, bits, cutters, and the like.  
22. REPLACEMENT PARTS. When servicing  
use only identical replacement parts.  
16. REDUCE THE RISK OF UNINTENTIONAL  
STARTING. Make sure switch is in off  
position before plugging in.  
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 elec-  
trician to install the proper outlet. Do not  
change the plug in any way.  
17. USE RECOMMENDED ACCESSORIES.  
Consult the owner’s manual for recom-  
mended 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.  
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 num-  
ber, 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.  
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.  
2. Use only wheels having a maximum oper-  
ating speed at least as high as “No Load  
RPM” marked on the tool’s nameplate.  
Use only fiberglass-reinforced cut-off  
wheels.  
7. Do not operate the tool without guards in  
place. Check wheel guard for proper clos-  
ing 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.  
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 sep-  
arate during this test.  
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. Secure the wheel carefully.  
5. Use only flanges specified for this tool.  
4
 
11. Before using the tool on an actual work-  
piece, let it run for a while. Watch for  
vibration or wobbling that could indicate  
poor installation or a poorly balanced  
wheel.  
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.  
12. Watch out for flying sparks when operat-  
ing. They can cause injury or ignite com-  
bustible materials.  
17. Turn off the tool and wait for the wheel to  
stop before moving workpiece or chang-  
ing settings.  
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.  
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.  
14. Use the cutting edge of the wheel only.  
Never use side surface.

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.

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 com-  
pleted, switch off the tool and WAIT UNTIL THE WHEEL  
HAS COME TO A COMPLETE STOP before returning the  
handle to the fully elevated position.  
OPERATION  
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.
