PowerLuber Grease Gun (Lithium)

GENERAL DESCRIPTION

The Lincoln PowerLuber is a Lithium-Ion
battery operated grease gun. The gun was
developed for manual lubrication of grease
points and includes a pressure relief valve,
LED and electronic control center.
The PowerLuber is driven by a small, low
voltage electric motor connected to a three-
stage planetary gear transmission. The rotary
motion of the motor is converted into a recip-
rocating motion of the plunger using a yoke
mechanism. The PowerLuber is a positive
displacement single acting pump.

Relief Valve

The safety valve (fig. 1) is factory set to
relieve pressure above 7500 psi (517 bar).
The valve also is an indicator of the bearing
and lubrication line conditions. If grease
comes out of the relief valve, it indicates a
clogged or tight bearing or fitting or line. Cor-
rect this before continuing lubrication with the
PowerLuber.

Control center

The tool is equipped with a control center that
consists of: PC Board with Display, LED light and
Set keys "A" and "B". Control center provides the
following functions:
• Motor protection. It will stop the motor if the
gun runs continuously at maximum pressure.
The display will flash red until the thermal
protector self resets;
• Displays the current level of battery charge;
• Monitors the level of the grease in tube;
• Calculates and displays the amount of the
grease delivered in, oz. PCB converts stroke
count to grease delivery.
• Allows control of an exact amount of grease
to lubricate critical bearings;
• Illuminates the LED light.
