It is not designated to handle salt water, brine, laundry discharge, or any other application which may contain caustic chemicals and/or foreign material. This pump is not suitable for use with aquatic life. Pump damage or failure could occur if used in these applications and will void the warranty.
• Do not pump flammable or explosive fluids such as gasoline, fuel oil, kerosene, etc. Do not use in a flammable and/or explosive atmosphere. Personal injury and/or death could result.
• Not for potable water or other potable liquids.
• Do not pump water with a temperature over 140°F (60°C). Do not pump sand, particulate, or large debris. Damage to the pump will occur.
• Do not allow pump to run dry for more than 10 seconds. Turn off pump quickly when job is complete. Damage to the pump could occur.
• Do not allow this pump to operate unattended. Failure to follow this warning could result in personal injury and/or death.
• Do not pump water from a creek, pond, or source where foreign objects may be sucked into the pump. Solids may enter the inlet hose.
• Always remove battery pack before attempting to install or service the pump. Never handle pump with wet hands or when standing on a wet or damp surface or in water. Fatal electrical shock could occur.
• Secure the discharge hose before starting the pump. An unsecured discharge hose may whip. Personal injury and/or death could result.
• Do not use the pump if the switch does not turn it on and off. Any pump that cannot be controlled with the switch is dangerous and must be repaired.
• Always remove battery pack from the pump before making any adjustments, changing accessories, or storing appliance. Such preventive safety measures reduce the risk of starting the appliance accidentally.
• Maintain pump and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the pump’s operation. If damaged, have the pump repaired before use. Accidents can be caused by a poorly maintained pump.
• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

WORK AREA SAFETY

• Keep work area clean and well lit. Cluttered or dark areas invite accidents.
• Do not operate pump in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Motors create sparks which will ignite the dust or fumes.
• Keep bystanders, children, and visitors away while operating pump. Distractions will result in mistakes.
• Indoor use only.

PERSONAL SAFETY

• Stay alert, watch what you are doing and use common sense when operating this pump. Do not attempt to operate this pump while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention 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 could be caught in moving parts.
• Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control in unexpected situations.
• Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes and hard hat must be used for appropriate conditions.
• Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

BATTERY TOOL USE AND CARE

• Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
• Use pumps only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
• 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.
• 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.
• Do not use a battery pack or tool that is dam- aged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.
• Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 265°F (130°C) may cause explosion.
• Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

SERVICE

• Disconnect the battery pack from pump. Release all pressure within the system before servicing any component.
• Drain all liquids from system before servicing.
• Periodically inspect pump and system components, checking for weak and/or worn hoses. Check impeller for wear or blockage. Ensure all connections are secure.
• When servicing a pump, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow maintenance instructions may create a risk of electrical shock or injury and may void the warranty.
• Do not modify or attempt to repair the pump or the battery pack except as indicated in the instructions for use and care.
• Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

ADDITIONAL SAFETY RULES

• Always use common sense and be cautious when using tools. It is not possible to anticipate every situation that could result in a dangerous outcome. Do not use this tool if you do not understand these operating instructions or you feel the work is beyond your capability; contact Milwaukee Tool or a trained professional for additional information or training.
• Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE service facility for a free replacement.
• Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
• lead from lead-based paint
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
  Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.
