GENERAL DESCRIPTION

The Lincoln PowerLuber is a battery oper-
ated grease gun. The gun was developed
for manual lubrication of grease points and
includes a pressure Safety Valve, a circuit
breaker and stroke counter.
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 relief© valve (fig. 1) is factory set to
relieve pressure above 7000 PSI (482 bar).
The valve also is an indicator of the bearing
and lubrication line conditions. If grease
comes out of the Safety Valve, it indicates a
clogged or tight bearing or fitting or line. Cor-
rect this before continuing lubrication with the
PowerLuber.

Circuit Breaker

The circuit breaker is used for double protec-
tion of the motor. It will stop the motor if gun is
run continuously at maximum pressure.

The circuit breaker also is an indication of the
bearing or lubrication line conditions. If the red
button is popping out this is an indication of
clogged or tight bearing, clogged grease fitting or
blocked lubrication line. Correct this before reset-
ting and continue lubrication with PowerLuber.

Stroke counter

The tool is equipped with capability for calibra-
tion. This is accomplished by measuring (weigh-
ing) grease flow output and dividing the weight
of grease by number of strokes. Simply put your
thumb on the stroke counter button (Fig. 1)
during operation of the tool and count.
Some OEM's are recommending the exact
amount of grease to lubricate critical bearings.
By counting the strokes you will know how much
grease has been dispensed to lubricate the
bearing. Here is the table of the grease output
vs. number of strokes.
