1.Work area safety

a.Keep work area clean and well lit.

Cluttered or dark areas invite acci- dents.

b.Do not operate the Scale in explo- sive atmospheres, such as in the presence of flammable liquids, gases or dust. Line operated and battery operated equipment cre- ate sparks which may ignite dust or fumes.

c.Keep children and bystanders away while operating the Scale.

Distractions can cause you to lose control.

2.Electrical safety

a.The Power Plug (17) must match the outlet. Never modify the Plug in any way. Do not use any addi- tional adapter plugs with the Scale.

Unmodified plugs and matching out- lets will reduce risk of electric shock.

b.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.

c.Do not expose the Scale to rain or wet conditions. Water entering the

Scale will increase the risk of electric shock.

d.Do not abuse the Power Cord (17). Never use the Cord for car- rying, pulling or unplugging the Cord. Keep the Cord away from heat, oil, sharp edges or moving parts. Damaged or entangled Cords increase the risk of electric shock.

e.When operating the Scale out- doors, use an extension cord suit- able for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

f.If operating the Scale in a damp location is unavoidable, use a Ground Fault Circuit Interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.

3.Personal safety

a.Stay alert, watch what you are do- ing and use common sense when operating the Scale. Do not use the Scale while you are tired or un- der the influence of drugs, alcohol or medication. A moment of inatten- tion while operating the Scale may result in serious personal injury.

b.Use safety equipment. Always wear eye protection. Safety equip- ment such as ANSI-approved safety impact goggles will reduce personal injuries.

c.Prevent unintentional starting. Ensure the Power Switch (15) is in the off-position before connect-

ing to power source and/or bat- tery pack, picking up or carrying the tool. Carrying battery operated equipment with your finger on the

Power Switch or energizing equip- ment that have the Power Switch on invites accidents.

d.Do not overreach. Keep proper footing and balance at all times.

This enables better control of the

Scale in unexpected situations.

4.Scale use and care

a.Do not force the Scale. Use the correct Scale for your application.

The correct Scale will do the job bet- ter and safer at the rate for which it was designed.

b.Do not use the Scale if the Power

Switch (15) does not turn it on and off. Any equipment that cannot be controlled with the Power Switch is dangerous and must be repaired.

Grounding

To prevent electric shock

and death from incorrect grounding wire connection:

Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the Power Cord Plug provided with the Scale. Never remove the grounding prong from the Plug. Do not use the if the Power Cord or Plug is damaged. If damaged, have it repaired by a service facility before use. If the Plug will not fit the outlet, have a proper outlet installed by a qualified electrician.

Grounded Tools: Tools with Three Prong Plugs

1.Equipment marked with ???Grounding

Required??? have a three wire cord and three prong grounding Plug. The

Plug must be connected to a properly grounded outlet. If the equipment should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user, reducing the risk

of electric shock.

(See 3-Prong Plug and Outlet.)

2.The grounding prong in the Plug is connected through the green wire inside the Cord to the grounding system in the equipment. The green wire in the Cord must be the only wire connected to the equipment???s grounding system and must never be attached to an electrically ???live??? termi- nal.

(See 3-Prong Plug and Outlet.)

3.The equipment must be plugged into an appropriate outlet, properly in- stalled and grounded in accordance with all codes and ordinances. The Plug and outlet should look like those in the preceding illustration.

(See 3-Prong Plug and Outlet.)

Extension Cords

1.Grounded equipment require a three wire extension cord. Double Insu- lated equipment can use either a two or three wire extension cord.

2.As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using exten- sion cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and pos- sible tool damage.

The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord. (See Table A.)

3.When using more than one exten- sion cord to make up the total length, make sure each cord contains at least the minimum wire size required.

(See Table A.)

4.If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum cord size. (See Table A.)

5.If you are using an extension cord outdoors, make sure it is marked with the suffix ???W-A??? (???W??? in Canada) to indicate it is acceptable for outdoor use.

6.Make sure the extension cord is prop- erly wired and in good electrical con- dition. Always replace a damaged extension cord or have it repaired by a qualified electrician before using it.

7.Protect the extension cords from sharp objects, excessive heat, and damp or wet areas.
