4. Use safety equipment.
Wear ANSI-approved safety goggles
and heavy-duty work gloves during use.
5. Dress properly. Do not wear
loose clothing or jewelry. Contain
long hair. Keep hair, clothing, and

Kit. Use the correct product for your
application. The correct product
will do the job better and safer at

9. Use only accessories that are
recommended by the manufacturer
for the specific tool model.
Accessories that may be suitable for
one product may become hazardous
when used on another product.
10. Keep cutting tools sharp and clean.
Properly maintained cutting tools with
sharp cutting edges are less likely
to bind and are easier to control.
11. Protect the Pressure Hose.
Do not drop heavy objects on
the Hose. Avoid kinks in the Hose.
Maintain proper clearance to avoid
damage to the Hose and Coupler.
12. Maintain labels and nameplates.

work of larger industrial products. Do
not use this product for a purpose
for which it was not intended.
14. Tool service must be performed
only by a qualified service
technician. Service or maintenance
performed by unqualified personnel
could result in a risk of injury.
15. When servicing the Punch Driver
Kit, use only identical replacement
parts. Use only authorized parts.
16. Keep children and bystanders away
while operating a tool. Distractions
can cause you to lose control.
