GENERAL SAFETY RULES
WARNING! Read and understand all instructions. Failure to follow all instructions listed
below may result in electric shock, fire and/or serious injury.
WARNING! The warnings, cautions, and instructions discussed in this instruction
manual cannot cover all possible conditions or situations that could occur. It must be
understood by the operator that common sense and caution are factors which cannot be built
into this product, but must be supplied by the operator.
SAVE THESE INSTRUCTIONS
Every pump is carefully tested and packed during its assembly. On receiving the
pump, check that pump has not been damaged during transportation. If the pump is
damaged, immediately inform the dealer within 8 days from the date of purchase.
WORK AREA
• Keep work area clean, free of clutter and well lit. Cluttered and dark work areas can
cause accidents.
• Do not use where there is a risk of causing a fire or an explosion; e.g. in the presence
of flammable liquids, gasses, or dust. Some tools create sparks, which may ignite the dust
or fumes.
• Keep children and bystanders away while operating this tool. Distractions can cause
you to lose control, so visitors should remain at a safe distance from the work area.
• Be aware of all power lines, electrical circuits, water pipes and other mechanical hazards
in your work area, particularly those hazards below the work surface hidden from the
operator's view that may be unintentionally contacted and may cause personal harm or
property damage.
• Be alert of your surroundings. Using tools in confined work areas may put you
dangerously close to cutting tools and rotating parts.
ELECTRICAL SAFETY
WARNING! Always check to ensure the power supply corresponds to the voltage on the
rating plate.
• Do not abuse the cord. Never carry a portable tool by its power cord, or yank tool or
extension cords from the receptacle. Keep power and extension cords away from heat, oil,
sharp edges or moving parts. Replace damaged cords immediately. Damaged cords may
cause a fire and increase the risk of electric shock.
• Grounded tools must be plugged into an outlet properly installed and grounded in accor-
dance 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.
• Double insulated tools 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 doesn't fit, contact a qualified electrician to install a polar-
ized outlet. Do not change the plug in any way.

• Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrig-
erators. There is an increase risk of electric shock if you body is grounded.
• When operating a power tool outside, use an outdoor extension cord marked “W-A” or
“W”. These cords are rated for outdoor use and reduce the risk of electric shock.
• Extension Cord Use.
A. Use only 'Listed' extension cords. If used outdoors, they must be marked “For Outdoor
Use.” Those cords having 3-prong grounding type plugs and mating receptacles are to be
used with grounded tools.
B. Replace damaged or worn cords immediately.
C. Check the name plate rating of your tool. Use of improper size or gauge of extension
cord may cause unsafe or inefficient operation of your tool. Be sure your extension cord
is rated to allow sufficient current flow to the motor. For the proper wire gauge for your
tool, see chart.
CHART FOR MINIMUM WIRE SIZE OF EXTENSION CORD:
If in doubt, use larger cord. Be sure to check voltage requirements of the tool to your
incoming power source.
• Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
• Do not let your fingers touch the terminals of plug when installing to or removing from
the outlet.
• Ground fault circuit interrupters. If work area is not equipped with a permanently
installed Ground Fault Circuit Interrupter outlet (GFCI), use a plug-in GFCI between power
tool or extension cord and power receptacle.
PERSONAL SAFETY
• Stay alert, watch what you are doing and use common sense when operating a power
tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or
medication. A moment of inattention while operating power tools may result in serious
personal injury.
• Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewelry or long hair can be
caught in moving parts. Air vents often cover moving parts and should be avoided.
• Use safety apparel and equipment. Use safety goggles or safety glasses with side
shields which comply with current national standards, or when needed, a face shield. Use
as dust mask in dusty work conditions. This applies to all persons in the work area. Also
use non-skid safety shoes, hardhat, gloves, dust collection systems, and hearing protec-
tion when appropriate.
• Avoid accidental starting. Do not carry the power tool with your finger on the switch.
Ensure the switch is in the off position before plugging tool into power outlet. In the event
of a power failure, while a tool is being used, turn the switch off to prevent surprise starting
when power is restored.

• Do not overreach. Keep proper footing and balance at all times.
• Remove adjusting keys or wrenches before connecting to the power supply or turning
on the tool. A wrench or key that is left attached to a rotating part of the tool may result in
personal injury.
TOOL USE AND CARE
• Do not force the tool. Tools do a better and safer job when used in the manner for which
they are designed. Plan your work, and use the correct tool for the job.
• Never use a tool with a malfunctioning switch. Any tool that cannot be controlled with
the switch is dangerous and must be repaired by an authorized service representative
before using.
• Disconnect power from tool and place the switch in the locked or off position before
servicing, adjusting, installing accessories or attachments, or storing. Such preventive
safety measures reduce the risk of starting the power tool accidentally.
• Store idle tools. When tools are not is use, store them in a dry, secure place out of the
reach of children. Inspect tools for good working condition prior to storage and before re-use.
• Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool may create a risk of injury when used on
another tool.
• Keep guards in place and in working order.
