GENERALDESCRIPTION
This Rechargeable Grease Gun is a fully automated, battery powered grease gun developed for manual
lubrication of greasepoints. It includes a pressure relief valve to expel excessivepressure(8000 psi) in the
case of a blocked bearing, fitting, or lubrication line. This Rechargeable Grease Gun is driven by a small,
low voltage electric motor connectedto a three-stage planetary gear reducer. The rotary motion of the
motor is converted into a reciprocating motion of the plunger through an eccentric and yoke mechanism.
This Rechargeable Grease Gun is a positive displacement single acting pump.

OPERATION
Primethe rechargeable greasegun after each refill or grease cartridge change. Primethe gun before
using it to lubricate greasepoints.
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 greasegun 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 greasegun, 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. Whenthe tool is unable to perform the
task at hand, it is time to recharge the battery pack. Rechargingthe battery pack before this condition is
reached will reduce the total worklife of the pack. Discharging the pack beyond this point can damagethe
pack.
NOTE: Batterytemperature will increaseduring and shortly after use. Batteries may not accepta full
charge if they are chargedimmediately 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 surethe power circuit voltage is the sameas that shown
on the charger specificationplate, than connect to power source.
Removing the batterypack
Depress the two battery release buttons (one button on each
side of battery pack) and pull the battery pack from the grease
gun.

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.

HOWTO FILLTHE GUN WITH AFILLER PUMP
Insert the gun filler nipple into the filler pumpsocket. Operate the filler pump to fill the container. Stop the
filler pumpwhen the follower rod extends to approximately 8 inches (20 cm). (See Figure 4)
Pushthe follower rod into the grease tube assemblyby pressingthe locking lever.
HOWTO EXPEL AIR POCKETS
Withdraw the follower rod from the grease tube assemblycapand engage it with the follower by rotating
the follower handle. Exert forceon 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 canadjust the screw inside the grease releasevalve, then both grease and air will be
expelled.
ASSEMBLY AND MAINTENANCENOTES(seefigures 5and 6)
It is also normalfor lithium ions batteries to gradually losetheir power retention capacity over hundreds of
charge cycles. Whenthis happens, replacementof the battery packwill be required.
The 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.
