(12). The mark on the latter must be pointing downwards. Tighten the securing
bolt of the pressure roller in the direction of the shaft mark. Insert the selected
counterpressure roller. Note the position of the drive dog (flat edge) on the rear
end of the counterpressure roller. Tighten the securing bolt.
3.2. Working procedure
Pipe ends must be cut off at right angles. Welds or welding residues (beads)
in the pipe must be sanded off over a length of some 50 mm from the pipe end.
Clean any dirt and scale off the inside and outside of the pipe ends.
Close the pressure limiting valve (16). Place the pipe on the counterpressure
roller and press it against the machine. Align the pipe axis-pa rallel, supporting
it as necessary. Operate the feed lever (15) of the hydraulic hand pump several
times and feed the pressure roller (11) forward until it is up against the pipe.
Set the stop for the groove depth (17); to do so, turn the setting disc for groove
depth (18) to a stage corresponding to the pipe size between the housing and
the stop plate, and move the stop inwards until it is up against the setting disc.
Secure the stop plate using a locking nut. Turn the setting disc back to the
engagement position so that the stop plate can be moved downwards. Operate
the machine at top speed. Switch on the machine using the pedal switch (4),
operate the feed lever (15) several times, and slowly slide the pressure roller
(11) into the pipe while the machine is running until the stop plate is touching
the housing (pressure on feed lever increases). Keep the machine running a
few more turns without feed. Then shut down the machine, open the pressure
limiting valve (16), remove the pipe, and check the groove made. To do so, use
the diameter measuring tape or the slide rule at a 90° angle. If necessary, adjust
the stop (17) and repeat the procedure. 1 scale graduation on the stop plate
corresponds to an infeed of approx. 0.4 mm, a complete revolution is 1.5 mm.
3.3. Support of the material
CAUTION Pipes and long pipe sections must be supported. Ensure here
that the support keeps the pipe at righ
4. Maintenance
WARNING
Pull out the mains plug before maintenance and repair
work! This work may only be performed by qualified personnel.
4.1. Servicing
Lubricate the roll grooving unit at the lubricating nipple (19) every 40 working
hours. Use ROLLER'S transmission grease, article no. 091012.
4.2. Inspection/maintenance
See also the instructions for use of the respective drive machine ROLLER'S
Robot.
Check the hydraulic oil level regularly. To do so, unscrew the hydraulic hand
pump and hold it with its rear end vertically upward. Open the pressure limiting
valve (16), unscrew the oil dipstick (20) in the lid of the container, and check
the oil level. If necessary, top up with ROLLER'S hydraulic oil, article no. 091026.
Always heed the marks on the oil dipstick – do not pour in too much oil.
Change the hydraulic oil completely at last every 12 months. To do so, tilt the
container to drain off the old oil, which must be disposed of without harming
the environment.
