● After 45 minutes, the left LED turns green steady indicating that the battery is fully charged.
● Remove the battery by pressing the two locking clips 6 and extract it from the charger.
● Disconnect the charger from the power supply.
Comment:
● If the left LED flashes green and red, this means that there is a temperature problem for the battery charge. The battery
must be charged between 10° and 40°.
The temperature of the battery increases while the press fitting machine is in use. The battery will not be fully charged if it
is recharged immediately after use.
You must let it cool down before setting it to charge again.
● If the left LED remains lit red, this means that the battery is damaged. In this case, you must replace it with a new
battery.
Inserting the battery in the press fitting machine
● Align the four rails of the battery with the four grooves on the bottom of the tool's handle and push until a click is heard.
Using the M20+ press fitting machine
Selecting the correct inserts
Use the insert profiles and diameters recommended in the instructions supplied with the pipe fittings.
Preparation of pipes
● Ensure that the fitting is suitable for the diameter of the pipe and that the material and the thickness of the pipe are
compatible with the fitting.
● Cut the pipe perpendicular to its centreline. Ensure that the cut is cleanly formed, in particular where elastomer seals
are used. Burrs and sharp edges must be removed by forming a chamfer.
● The ends of the pipes must be restored to their initial external diameter over a minimum length exceeding the depth of
insertion into the fitting. The pipe must be sized only using tools specifically designed for that purpose. The pipe must be
re-cut if incorrectly sized.
● The ends of the pipes must be free of scratching or pitting over a length a minimum length exceeding the depth of
insertion into the fitting.
● When working on a refurbishment scheme, it is particularly important to ensure that all traces of paint are removed over
a minimum distance exceeding the depth of insertion into the fitting.
Forming a press fit joint
Placing the fitting
● Select the correct fitting for the pipe to be joined.
● Slide the fitting onto the pipe.
Inserting the fitting into the inserts and pressing
● Select the correct inserts for the fitting.
● Open the main jaw by pressing on the two arms.
● Slide the fitting over the inserts, keeping the main jaws open.
● Release pressure on the main jaws and check that the two inserts close properly over the fitting.
● Check that fitting is properly positioned in the inserts.
● After checking, press the trigger (7) and hold it down until the pressing cycle is completed (return cycle). The machine
will automatically retract when the press fit joint is properly formed. The LED (8) will remain lit to indicate that the joint is
correctly formed (pressing force achieved).
● If the trigger is released before the cycle has been completed, the machine stop and remain in position. Holding down
the trigger will resume and complete the cycle.
● In the event of an abnormal situation requiring reversal of operation before completing the pressing cycle: Release the
trigger to stop the machine, then apply a very brief pressure to return the machine to its earlier position.
Removing the fitting from the inserts
● Open the main jaw by pressing the two arms.
● Remove the inserts from the fitting.
Fault monitoring
● If a cycle is activated without the main jaw in place, the machine will perform a short return cycle then switch to fault
mode (inhibited operation). Disconnect and reconnect the battery to return to normal operation.
● The pressing timer will switch the machine to fault mode if an excessive drop in battery charge level is detected. The
indicator will flash and the machine will prevent the next cycle being performed. Insert a charged battery to return to
normal mode.
