2 DELIVERY, COMMISSIONING AND SET-UP

2.01 DELIVERY

The machine is normally shipped and delivered inside

a special hard case, well secured and in a stable

position (see adjacent figure). All materials shipped

are checked prior to delivery.

Upon receipt, check the machine for any damage (breakages or major denting)

caused during transport. If so, it is necessary to immediately inform the shipping

company and to write on the Delivery note the “Accepted subject to checking"

clause.

In the event of damage, send a written complaint to the forwarder within 8 days of

receipt.

Promptly inform Edilgrappa s.r.l. if major damage, caused during transport, is

found upon receipt, or if any parts are missing.

It is also necessary to check the delivered materials against the detailed shipping

list.

The machine can be moved easily both when it is inside its special rigid case, using the

upper handle, and by gripping its upper or lower handle.

Loads must be moved in compliance with current occupational safety regulations.

After use, put the machine back into its case or place it on a stable surface, making sure

this can withstand its weight.

TURN THE MAIN SWITCH TO OPEN POSITION "O".

2.02.02 COMMISSIONING

These machines do not need any adjustment or particular precautions before

commissioning.

The only controls to perform concern:

- Machine integrity:

make sure that nothing happened during transport that could damage the insulation or

mechanical parts.

- Completeness of supply:

check that all the supplied accessories are fitted.

- Oil level:

check the oil level and top up if necessary as per the instructions in Para 3.01.

IMPORTANT: Before loosening the oil cap carefully read the instructions in Para

3.01.

2.03 DOUBLE-ACTING LEVER

The double-acting lever has two positions (see fig. 2)

-Position 1 ( open ): The piston returns to its original position.

-Position 2 ( close ): The piston performs its outward stroke (bending-straightening

phase).
