5. Operating Instructions
5) Use the hydraulic pump to start the grooving
process. (Fig. 25)
ޓ
Refer to the table below for how to operate
the pump safely.
6) As soon as the adjusting nut touches the upper
surface of the cylinder, switch the machine OFF
and stop pumping. (Fig. 26)
4. Checking the dimensions
ޓ
Be sure to check the depth of the groove and the
dimensions of each part of the machined pipe
according to Table 6 below.
ޓ
If the handle is pushed too quickly, the pipe may
become distorted and the machine may break
down. Be careful to use the handle correctly.

CAUTION
The specified size for each part of the pipe
may differ slightly, depending on the joint.
In such a case, make sure you check the
machining size according to the specified
size table for the joint used.
Push the handle once for each
rotation of the pipe.
Push the handle once for every
two rotations of the pipe.
