Safety Warnings and Precautions
WARNING: When using product, basic safety precautions should always be followed to
reduce the risk of personal injury and damage to equipment.

Read all instructions before using this product!

WORK AREA

1. Keep your work area clean and well lit. Cluttered benches and dark areas invite

accidents.

2. Do not operate the Ultrasonic Cleaner in explosive atmospheres, such as in the

presence of flammable liquids, gases, or dust. Electrical products create sparks which
may ignite the dust or fumes.

3. Keep bystanders, children, and visitors away while operating the Ultrasonic Cleaner.

Distractions can cause you to lose control.

ELECTRICAL SAFETY

4. This product has a 3-prong electrical plug, and must be plugged into an outlet

properly installed and grounded in accordance with all codes and ordinances. Never
remove the grounding prong or modify the plug in any way. Do not use any adapter
plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is
properly grounded. If a grounded prouct should electrically malfunction or break down,

grounding provides a low resistance path to carry electricity away from the user.

5. Double insulated products 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 eliminates the need for the three wire grounded power cord and
grounded power supply system.

6. 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.

7. Do not abuse the Power Cord. Never use the Power Cord to carry the Ultrasonic
Cleaner or pull the Plug from an outlet. Keep the Power Cord away from heat, oil,
sharp edges, or moving parts. Replace damaged Power Cords immediately. Damaged

Power 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 extension 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 the
Ultrasonic Cleaner. Do not operate this porduct while tired or under the influence of
drugs, alcohol, or medication. A moment of inattention while operating the Ultrasonic

Cleaner 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 the Power Switch is off before plugging in.
Carrying appliances with your finger on the Power Switch, or plugging in appliances with
the Power Switch on, invites accidents.

12. Remove adjusting keys or wrenches before turning the Ultrasonic Cleaner on. A
wrench or a key that is left attached to a rotating part of the Ultrasonic Cleaner 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 power 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. Wear full face shield
to protect against chemical splashing.

TOOL USE AND CARE

15. Do not overload the Ultrasonic Cleaner. Use the correct Ultrasonic Cleaner for your

application. The Ultrasonic Cleaner will do the job better and safer at the speed and capa-

city for which it is designed.

16. Do not use the Ultrasonic Cleaner if the Power Switch does not turn it on or off. Any
appliance that cannot be controlled with the Power Switch is dangerous and must be
replaced.
