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.
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.
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.
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 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.
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.
