GENERAL SAFETY INSTRUCTIONS
Carefully read these operating instructions thoroughly before unpacking and operating this Rechargeable
Grease Gun.
•A battery operated Rechargeable Grease Gun with a separate battery pack must be recharged only with
the specified battery charger. A charger that may be suitable for one type of battery may create a risk of
fire when used with another battery. Use this battery operated tool only with the specifically designed
battery pack. Use of any other batteries may create a risk of fire. Batteries are shipped in an uncharged
state. Charge batteries for 1 hourbefore first use.
•Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases
or dust. The Rechargeable Grease Gun can create sparks which may ignite the dust or fumes. Keep
bystanders, children and visitors away during operation. Distractions can cause you to make mistakes.
•Do not use the battery charger in damp or wet locations.
•Always use safety glasses and gloves for protection during operation. The Rechargeable Grease Gun can
generate up to 8000 psi. Grease injection injuries are a very serious injury. Avoid accidental starting. Be
sure the switch is not depressed when inserting battery pack. Do not bend the hose so that it becomes
kinked.
•Do not continue to hold down trigger if the grease gun is stalled. This could damage the motor or cause
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 battery terminals together may cause sparks, burns, or a fire. Use only accessories that are
recommended for use with the Rechargeable Grease Gun. This tool is a fully rated portable power
lubrication product. Only accessories that are capable or handling 8000 psi should be used.
•Service must be performed only by qualified service personnel. Service or maintenance performed by
unqualified personnel may result in a risk of injury. When servicing this Rechargeable Grease Gun, use
only same replacement parts. Use of unauthorized parts may create risk of injury and will void the
warranty.
•Visually inspect for damaged, loosen or missing parts. If equipment is worn or damaged, remove from
service. Contact sales for damage assessment or repair.
SAFETY INSTRUCTIONS FOR CHARGER & BATTERY
This section of the manual contains important safety and operating instructions for the charger.
Before using a battery charger, read all instructions and cautionary markings on the battery pack, battery
charger, battery and rechargeable grease gun.
•Do not expose charger to rain, snow or frost.
•Do not pull on or otherwise abuse cord. Never pull charger by the cord when disconnecting charger. Have
damaged or worn power cord replaced immediately.
•Do not attempt to repair the power cord. Make sure cord is located so that it will not be stepped on, tripped
over, or otherwise subjected to damage or stress.
•Do not operate charger with a damaged cord or plug. Have the cord replaced immediately to avoid a
hazard. Do not attempt to repair the power cord.
•Do not operate the charger if it has received a sharp blow, been dropped, or otherwise damaged in any
way. Take it to a qualified serviceman for repair.
•Do not disassemble the charger or the battery pack. Take it to a qualified serviceman when service or
repair is required.Incorrect reassembly may result in risk of electrical shock or fire.
•Unplug charger from outlet before attempting any maintenance or cleaning to reduce risk of electrical
shock.
•Charge the battery pack in a well ventilated place. Do not cover the charger and battery while charging.
•Do not store the charger or battery packs in locations where the temperature may reach or exceed 50C°
(122°F). This can lead to deterioration of the batteries.
•Do not charge the battery pack when temperature is below 0°C (32°F) or above 40°C (104°F). This is very
important for proper operation.
•Do not incinerate battery pack as it can explode in a fire.
•Extremely high temperatures could cause personal injury or fire.
•Do not charge battery in damp or went locations.
•Do not short across the terminals of the battery pack.

OPERATION
Prime the rechargeable greasegun after each refill or grease cartridge change. Primethe gun before
using it to lubricate grease points.
CAUTION
Air pockets in the lubricant cartridge will cause the gun to lose its prime.
To prime, operate the gun until grease flows from the hose.
Otherwise, you can use the vent valve and the release grease valve to expel air pockets.
CHARGER OPERATION CHARGING THE BATTERY PACK
Before using your rechargeable grease gun for the first time, the battery pack should be charged for a
minimum of 1 hour. If the battery pack is already installed in the rechargeable grease gun, removeit by
following the instructions under installing or removing battery pack. As the battery packapproaches the
dischargedstate, 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 worklife of the pack. Dischargingthe pack beyond this point can damage the
pack.
NOTE:Batterytemperature will increaseduring 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 the charger must not be obstructed.
Do not charge the battery pack when temperature is below 0°C (32°F) or above 40°C (104°F).
Normal charging
Make sure the power circuit voltage is the sameas that shown
on the charger specification plate, than connect to power source.
Removing the batterypack
Depress the twobattery release buttons (one button on each
side of battery pack)and pull the battery pack from the grease
gun.
Installing the battery pack
Align battery pack with opening in handle, and pushbattery pack
into handle until it locks into place.

HOW TO READ THE BATTERY CAPACITY DISPLAY
The LCD display shows the battery capacity whenever the button is pressed. It has
5 segments, each one representing 20% of the full capacity, i.e. three segments lit in the LCD display
indicates the battery is at 60% of its charge (See Figure 1).
BATTERY CAPACITY DISPLAY (Figure 1) LOCKING TRIGGER (Figure 2)
HOW TO USE THE SELF-LOCKING TRIGGER
There is a chance of getting the trigger pressed by children or something else when the grease gun is
being transported or just not being used. The grease gun could then be accidentally activated, spilling
grease all over. To avoid this, turn the button position from “Unlock” to “Lock” (See Figure 2).
NOTE: Do not press the trigger when the button is in the "Lock" position, this could destroy the self-
locking device.
HOW TO FILL THEGUN FROM A BULK CONTAINER
1. Remove pump assembly from grease tube assembly.
2. Pack lubricant into cavity of the pump assembly.
3. Insert the open end of the grease tube assembly into lubricant. Slowly pull the follower handle
back while pushing the grease tube assembly deeper into the lubricant to prevent air pockets
from being pulled into the grease tube assembly. (See Figure 3)
4. When the follower rod is fully extended, it will latch onto the locking lever.
5. Loosely assemble the pump assembly to the grease tube assembly. Press the locking lever while
pushing the follower rod into the grease tube assembly. Slowly unscrew the grease tube
assembly from the pump assembly until lubricant oozes from the interface. Tighten grease tube
assembly into the pump assembly.

HOW TO FILL THE GUN WITH A FILLER PUMP
Insert the gun filler nipple into the filler pump socket. Operate the filler pump tofill the container. Stop the
filler pump when the follower rod extendsto approximately 8 inches (20 cm). (See Figure 4)
Push the follower rod into the grease tube assembly by pressing the locking lever.
HOW TO EXPEL AIR POCKETS
Withdraw the follower rod from the grease tube assembly cap and engage it with the follower by rotating
the follower handle. Exert force on the follower handle while holding down the vent valve.
Pull the trigger in short bursts to operate gun until trapped air is expelled. Disengage the follower rod from
the follower by rotating the follower handle. Push the follower rod into the grease tube assembly.
If step 2 fails, you can adjust the screw inside the grease release valve, then both grease and air will be
expelled.
ASSEMBLY AND MAINTENANCE NOTES (see figures 5 and 6)
It is also normal for lithium ionsbatteries to gradually lose their power retention capacity over hundreds of
charge cycles. When this happens, replacement of the battery pack will be required.
The motor polarity is important, the positive (red wire) must be connected tothe positive terminal on the
motor, which is identified with the small plastic dot next to it.
The green ground wire must be secured underthe motor mounting screw.
