TURNING THE GREASE GUN ON/OFF
See Figure 2, page 11.
The lock-off button, located on the handle above the switch
trigger, reduces the possibility of accidental starting.
 To turn the tool on: Slide lock-off button to the unlocked
position, and press the switch trigger.
 To turn the tool off: Release the switch trigger and return
the lock-off button to the locked position.
CAUTION:
The lock-off button should be in the locked position when
the tool is not in use or is being transported.
LED LIGHT
See Figure 3, page 11.
The LED light, located on the front of the tool base, illuminates
when the switch trigger is depressed.
After the switch trigger is released, the LED light will remain
on for approximately 15 seconds before shutting off.
The LED light illuminates only when there is a charged battery
pack in the tool.
UNDERSTANDING NLGI RATINGS
NLGI ratings are used to express the thickness or fluidity of
grease. The higher the rating, the thicker the grease. This
grease gun is capable of handling grease with a thickness
rated up to NLGI #2. Grease with an NLGI #2 rating has a
consistency similar to peanut butter.
NLGI
No.
000 Very fluid; similar to cooking oil
00 Somewhat fluid; similar to applesauce
0 Very soft; similar to mayonnaise
1 Somewhat soft; similar to toothpaste
2 Creamy; similar to peanut butter
CAUTION:
Do not load grease rated higher than NLGI #2. Doing
so could cause the grease gun to stall, damage the
pressure-carrying components of the tool, and/or create
a bursting hazard.
OPERATION
Consistency
WARNING:
Always follow the grease manufacturer's instructions
printed on their product labeling for use, cleaning, and
storage. Clean grease tube thoroughly after each use.
Grease should be stored out of the reach of children.
Failure to do so may result in serious personal injury.
LOADING A GREASE CARTRIDGE
See Figures 4 - 5, page 12.
 Lock the switch trigger in the "off" position and remove
the battery pack.
 Turn the grease tube counterclockwise to loosen and
remove.
 Pull the spring-loaded grease tube handle completely
out. Then move it to the side into the narrow slot to lock
it into place.
NOTE: Make sure the grease tube handle is locked in
place before adding the grease cartridge.
 Use a clean dry cloth to remove any old grease from
inside the tube.
 Remove the plastic end cap from the bottom of a 13.7 -
14.5 oz. grease cartridge (not included).
 Insert the grease cartridge (not included) into the grease
tube with the bottom facing the grease tube handle.
 Remove the seal from the front of the grease cartridge
(not included).
 Place the grease tube back onto the grease gun and
rotate clockwise to secure.
NOTE: Be careful to avoid cross-threading, which can
cause the grease tube to leak during use.
 Grab the grease tube handle and move it away from the
narrow slot.
 Slowly allow the grease tube handle to move forward and
into the grease tube.
NOTE: After the cartridge is loaded, use the purge valve to
purge any air trapped in the grease tube. For more details,
see Using the Purge Valve later in the manual.
To remove an empty grease cartridge:
 Lock the switch trigger in the "off" position and remove
the battery pack.
 Pull the spring-loaded grease tube handle completely
out. Then move it to the side into the narrow slot to lock
