SAFETY INSTRUCTIONS
Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury. Please read carefully
WORK AREA
1. Keep your work area clean and well lit. Cluttered benches and dull areas muy cause accidents.
2. Do not operate power tools in explosive atmospheres such as in the presence of flammable liquids, gases, or dust.
Power tools create sparks that may ignite the materials.
3. Keep bystanders, children, and visitors away while operating a power tool. Distractions can lead you to lose control.
ELECTRICAL SAFETY
1. Avoid body contact with grounded surfaces such as pipes, couplers. There is an increased risk of electric shock if your
body is grounded.
2. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
PERSONAL SAFETY
1.Stay alert. Watch what you are doing and use common sense when operating a power tool. Do not use a power tool while
tired or under the influence of drugs, alcohol, or medication. A moment of intention while operating power tools may
result in serious personal injury
2. 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.
3. Avoid accidental starting. Be sure the Switch is released before plugging in. Carrying power tools with your finger on the
Trigger, or plugging in power tools with the Trigger depressed invites accidents.
4. Remove adjusting keys or wrenches before turning the power tool on. A wrench or a key that is left attached to a
rotating part of the power tools may result in personal injury
5. Do not overreach. Keep proper footing and balance at all times. Proper Tooting and balance enables better control of
the power tool in unexpected situations.
6. Use safety equipment. Always wear approved safety glasses underneath a full face safety shield Dust mask, non-skid
safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

CHARGING THE BATTERY PACK GENERAL
Before using Grease Gun for the list time, if the battery pack is installed in the gun,
remove it by depress the two battery release butions (one button on each side of
battery pack) and pull battery pack out of gun.
As a 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.
Start the charging process by plugging in the battery charger and inserting the
battery into battery charger slot After Termination of the charging (approx. 1-2h),
pull charger out of socket and remove battery.
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.
Insert the Battery Pack into the Charging Socket of the Charger. Then: plug the Charger into the nearest 230 volt, grounded,
electrical outlet. To start charging press the “Set” button on the Charger. Battery is charging when the green light
illuminates.
