Operating Instructions

■

Before operating the press, replace the oil plug (Ref. A, Fig. 5) on the pump with the

holed one (Ref. B, Fig. 5) supplied by the manufacturer.

■

Position the bed of the press (Ref. 1, Fig. 4) at the desired height, lifting it first on one

side and inserting one of the pins (2) into the hole in the press body directly beneath.

■

Then repeat this step for the other side as well.

■

Place the pins (2) at the desired points.

Model: 653B

Oil:

1.2 kg

WARNING

All work operations are to be made with the bed resting on the pins.

■

Position the prisms on the bed (1) (Ref. 3, Fig. 4)

■

Insert the lever of the pump (4) into its relative seat (5) on the pump.

■

Fig. 6 shows the uses relative to the positions of the two handles on the pump.

■

Actuate the lever to lower the ram, carry out the work, then bring the ram back to rest

position with the relative dial (Fig. 6).

Maintenance

■

Oil the moving parts of the press every six months, check and control operation of the

pressure gauge.

■

The hydraulic unit (cylinder/pump) is a sealed system. In case the hydraulic unit should

be replaced one day, it is necessary to fill oil through the filling hole on the pump (Ref.

6, Fig. 5). The pump has to be completely filled. This operation has to be done with the

ram at rest position, which means fully retracted. The oil in the hydraulic unit should be

replaced every two years, independently of the general conditions of the unit.

Use hydraulic oil with viscosity from 22° to 25°, as for example HLP 46.

If the oil level is too high, problems might be caused.

WARNING

Never use brake oil
