Warnings and advice for knurling

You must be familiar with the machine structure, its functions and the propulsion and lubrication
systems by reading the manual prior to starting operation.

Care and Maintenance

Maintenance instructions:

Ensure that the machine is disconnected before carrying out maintenance or adjustments.
Hydraulic liquid level:
Loosen the filling cap to add hydraulic oil (loss through the cylinder valve, remove all dirt in the
vicinity of the lid orifice). Remove all dirt around the filling orifice before adding oil
Unscrew the drain screw before emptying all the used dirty oil If you wish to remove the entire
hydraulic cylinder from the main unit lower the slide to the lower position, loosen the screws
fixed to the piston and the 10 screws from the pump seat.
Lubrication:
The lubricator for the roller shaft must be lubricated once a month and each time the roller set is
replaced.
Add lubricating grease to the pin bearings prior to reassembling them.
Filling the hydraulic cylinder with oil:
In the event that it is necessary to fill the oil tank. Proceed as follows:

Troubleshooting

Symptom
The groove is too narrow or
too wide

Before switching on the machine add oil as indicated in the manu-
al. Check that the hydraulic cylinder is full of oil.
Connection to earth and the fuse are required in the circuit. The
motor must be correctly connected. Never put the machine into
operation if overloaded. The upper roller and lathe screw must be
suitably selected according to table 1 to ensure optimum knurling.
The steel tubes must have both ends and the surface polished
before starting to make knurl. If the tube comes out of the lathe
screw increase the tube's degree of deviation. In the event of
knurling steel tubes with large diameters fix the four machine feet
as well as the three tube support feet to the ground using screws.
In the event of knurling in steel tubes with large diameters (over
165 mm), the tube could brusquely swing during the knurling
process due to roughness and poor grooving or could even cause
a malfunction. In order to solve this problem a tube stabiliser can
be ordered as an option.
A pipe stabiliser is provided specifically to solve this problem.
 Open the tap (1).
 Thoroughly clean away any dirt around the screw
(2). Ensure that no dirt remains.
 Open the screw (2).
 Fill using hydraulic oil.
 Fit and secure the screw (2).
Possible Reason
The roller set does not
correspond to the tube
diameter
ENGLISH
Solution
Replace the roller set for
one which corresponds to
the tube diameter
