WORK AREA
•Keep work area clean, free of clutter, and well lit. Cluttered and dark work areas can cause
accidents.
•Do not use your tool where there is a risk of causing a fire or an explosion; e.g. in the
presence of flammable liquids, gasses, or dust. Power tools create sparks, which may ignite
the dust or fumes.
•Keep children and bystanders away while operating a power 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. These may be unintentionally contacted and can cause bodily injury or
property damage.
•Be aware of your surroundings. Using power tools in confined work areas may put you
dangerously close to cutting tools and rotating parts.

PERSONAL SAFETY
•Stay alert, watch what you are doing, and use common sense when operating a power tool.
Do not use a power tool when tired or under the influence of drugs, alcohol, or medication. A
moment of inattention while operating power tools may result in serious injury.
•Dress appropriately. 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.
•Proper safety apparel and equipment. Use safety goggles or safety glasses with side shields
that comply with current national standards. Use a face shield when necessary. Use a dust
mask in dusty work conditions. This applies to all persons in the work area. Also use
non-skid safety shoes, a hardhat, gloves, a dust collection system, and hearing protection
when necessary.
•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 using a tool, turn the switch to off to prevent a surprise start when power is
restored.
•Do not overreach. Keep proper footing and balance at all times.

TOOL USE AND CARE
•Do not force the tool. Tools do a better and safer job when used in the manner for which
they were designed. Plan your work, and use the correct tool for the job.
•Never use a tool with a malfunctioning switch. Any power tool that cannot be controlled with
the switch is dangerous and must be repaired by an authorized service provider before
using.
•Disconnect battery from the tool and place the switch in the locked or off position before
servicing, adjusting, installing accessories or attachments, or storing. Such preventative
safety measures reduce the risk of the power tool starting by accident.
•Secure work with clamps or a vise when practical. This safety precaution allows for proper
tool operation.
•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 for use with the Rechargeable Grease Gun.
Accessories that may be suitable for one tool may create a risk of injury when used on
another tool.
•This tool is a fully rated portable power lubrication product. Only accessories that are
capable of handling 7000psi should be used.
•Keep guards in place and in working order.
•Never leave the tool running unattended.
•Release the trigger if the grease gun is stalled. Holding down the trigger could damage the
motor or cause a 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 may cause sparks, burns, or a fire.
CHARGING THE BATTERY PACK
Before using the Rechargeable Grease Gun for the first time, the battery pack should be
charged for a minimum of 1.5 hours. If the battery pack is already installed in the Rechargeable
Grease Gun, remove it by following the instructions under INSTALLING or REMOVING
BATTERY PACK. As the battery pack approaches the discharged state, you will notice a sharp
drop in tool performance. When the tool is unable to perform the task at hand, it is time to
recharge the battery pack. Recharging the battery pack before this condition is reached will
reduce the total work life of the pack. Discharging the pack beyond this point can damage the
pack.
NOTE: Battery temperature will increase during and shortly after use. Batteries may not accept
a full charge if they are charged immediately after use. Allow the battery pack to cool to room
temperature before charging for best results.
CAUTION: Vent slots in top and bottom of charger must not be obstructed.
Do not charge battery when temperatures are BELOW 32°
°°
°F or ABOVE 104°
°°
°F.

MAINTENANCE
WARNING: Make sure the tool is disconnected from its power source before attempting
any maintenance, cleaning, or inspection.
•Maintain your tools. It is recommended that the general condition of any tool be examined
before it is used. Keep your tools in good repair by adopting a program of conscientious
repair and maintenance in accordance with the recommended procedures found in this
manual. If any abnormal vibrations or noise occurs, turn the tool off immediately and have
the problem corrected before further use. Have necessary repairs made by a qualified
service provider.
•Use only soap and a damp cloth to clean your tools. Many household cleaners are harmful
to plastics and other insulation. Never let liquid get inside a tool.
•It is normal for nickel-cadmium batteries to gradually lose their power-retention capacity over
hundreds of charge cycles. When this happens, replacement of the battery pack will be
required.
•Motor polarity is important; the positive (red wire) must be connected to the positive terminal
on the motor, which is identified with the small plastic dot next to it.
•The green ground wire must be secured under the motor mounting screw.
