"The rollers slide apart from
each other during loading."
The fault is probably in the holding valve (V26).
Clean the valve or have it tested by your dealer. If
necessary replace defective valve.
"The wrapping arm turns but
the rollers do not rotate."
The volume controlling valves for the rollers (V9/V13) are
closed or defective.
See section 9.0 and 14.3.
Dirt in one of the following valves: V14, V28 or V29. This
would cause the oil to leak back to the tank.
Clean the valves or replace if defective.
"The cutter does not function."
The solenoid valves (nos. 1 and 2), are not receiving power or
there is dirt in the valves.
See section 16.1 and 16.2.
The cutter cylinder is defective.
Replace.
The cutter lifts quickly but drops slowly.
The double pilot-controlled check valve is defective.
Replace.
"The cutter will not grip the
film."
The pressure in the cutter cylinder is dropping.
The fault is probably in the double pilot-controlled check valve.
(See section 14.2.)
Replace defective valve or have it tested by your dealer.
The fault could also be that the check valve that is fitted below
the pilot-controlled check valve is leaking.
Clean this valve or replace it with a new one.
"The cutter will not release the
film when the machine is
tested without a bale loaded."
When the machine is running idly, i.e. the wrapping arm and
rollers are turning without a loaded bale, it can happen that
there may not always be sufficient extra pressure to open the
pilot-controlled check valve (section 14-2) if the cutter is
closed with full pressure.
This can be avoided by not leaving the cutter closed with
full pressure. Therefore press the "CUTTER OPEN" (5)
button briefly.
(This problem cannot occur when a bale is being wrapped on
the machine.)

See section 16.1 and 16.2.

Replace defective valve or have it tested by your dealer.
