BATTERY CHARGE LEVEL
The gun is equipped with 2 operating modes, a LOW mode in which a
maximum flow rate of 100 g/min is obtained and a HIGH mode in which
flow rates of up to 160g/min are achieved (depending on the back
pressure and the type of grease and temperature). In both modes the
maximum working pressures of the gun can be reached, obtaining a
longer battery life in the LOW mode.
If LOW mode is active and a higher pressure is needed, the gun will
automatically change to HIGH mode.
To switch between the two operating modes, press button B, the display
will alternately show “H” (HIGH mode active) or “L” (LOW mode active).
When you are supplying grease, the display will show the amount of
grease dispensed in grams or ounces. To change units, press and hold
button A for 5” to toggle between the two units.
If during dispensing the gun detects a malfunction, the display will flash
in red to alert from this circumstance. These malfunctions can be mainly
due to priming loss or obstructions at the dispensing point (blocked
grease nipple). Once the anomaly disappears the display will no longer
flash in red.
The safety valve (18) is set at the factory to relieve the pressure if it
exceeds 500 bar (7250 psi). Grease leakage through the valve indicates
that this pressure has been reached due to a clogged fitting at the
lubrication point. If this is the case, check the line for the problem.
The grease gun is supplied with a shoulder strap for easy transport.
Attach the strap supplied to the strap mounts 6a and 6b. Adjust the strap
length to your needs.
The display shows 4 states of the battery charge level (15a) in graphic
form. When none of the bars are visible, recharge the battery according
to the recommended instructions.
This value is an approximate measurement and should not be used for
applications requiring high accuracy.
An estimate of the grease level in the tube is shown graphically on the
screen (15d). Pressing button “B” for 8” resets the counter to zero and
restores the full graphic grease level indicator (15d).
In the case of blocked grease fittings the gun is able to generate high
pressures trying to unblock it. If the obstruction persists, in addition to a
red flashing display, the motor might stop to avoid damage to the
equipment. If this occurs, stop dispensing and check the line or grease
fitting to proceed to repair or unblock it and once the issue is solved,
restart the dispensing.

NON-RETURN VALVE CLEANING
Dirt or particles may cause a failure of the grease dispenser. If the gun is
properly primed and grease delivery problems persist, perform the
following cleaning procedure:
1. Unscrew the safety valve.
2. Remove the spring and ball.
3. Clean the ball and valve seat.
4. Reassemble the ball and spring and tighten the safety valve.
