WARNING!
When using electric appliances, basic precautions should always be followed, including the following:

SAVE THESE INSTRUCTIONS
WORK AREA

Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.
Keep bystanders, children, and visitors away while operating an inflator. Distractions can cause you to lose control.
Operate inflator in an open area at least 18 in. away from any wall or object that could restrict the flow of fresh air to ventilation openings.

ELECTRICAL SAFETY

To reduce the risk of electrical shock, do not put inflator in water or other liquid. Do not place or store appliance where it can fall or be pulled into a tub or sink.
Use this product only with batteries and chargers listed in tool/appliance/battery pack/charger correlation supplement 987000-432.

PERSONAL SAFETY

Stay alert, watch what you are doing and use common sense when operating an inflator. Do not use inflator while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating inflator may result in serious personal injury.
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.
Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enable better control of the inflator in unexpected situations.
Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.
Eye protection is required to guard against flying fasteners and debris which could cause severe eye injury.
Do not wear loose clothing or jewelry. Contain long hair. Loose clothes, jewelry, or long hair can be drawn into air vents.
Do not use on a ladder or unstable support. Stable footing on a solid surface enables better control of the inflator in unexpected situations.
Do not disassemble the inflator.
Do not operate inflator near flammable liquids or in gaseous or explosive atmospheres. Internal sparks may ignite fumes.
Do not store in a damp or wet location. Do not use, store, or charge battery packs or products in locations where the temperature is less than 50° F or more than 100° F. Do not store in outside sheds or in vehicles.
Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.

INFLATOR USE AND CARE

Do not use inflator if switch does not turn it on or off. An inflator that cannot be controlled with the switch is dangerous and must be repaired.
Switch the tool off before making any adjustments, changing accessories, or storing the inflator. Such preventive safety measures reduce the risk of starting the inflator accidentally.
Store idle inflators out of reach of children and other untrained persons. Inflators are dangerous in the hands of untrained users.
Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the inflator’ s operation. If damaged, have the inflator serviced before using. Many accidents are caused by poorly maintained tools.
Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one inflator may create a risk of injury when used on another inflator.
Keep the inflator and its handle dry, clean and free from oil and grease. Always use a clean cloth when cleaning. Never use brake fluids, gasoline, petroleum- based products, or any strong solvents to clean your inflator. Following this rule will reduce the risk of loss of control and deterioration of the enclosure plastic.
