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).

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 THE GUN 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.
