3. MAINTENANCE
Please read the safety instructions provided at the beginning of this manual before
handling the following devices.
3.1. Hydraulics
4 It is important to clean the bars (even briefly) before loading them on the feed system magazine.
Excessive dirt can form a deposit at the base of the bar feeder, which can in turn slow the oil return.
3.2. Pneumatics
The air-filtering device is equipped with an automatic drainage valve, making it unnecessary to empty it.
The water recuperated comes from the pneumatic circuit of the building. It is advisable to make certain
that the air received by the bar feeder is as dry as possible (see Chapter 5 / Pneumatics).
3.3. Batteries
In the event of a power failure, a backup battery saves the data contained in the PLC. It is possible that
with time this battery will slowly drain; in this case a message will be displayed on the remote control. The
battery must be replaced as soon as possible with a battery of the same type. The same applies to the
SERVO amplifier.
3.4. Mechanics
Rotating sleeves
In order to guarantee the correct operation of the bar feeder, the rotating sleeve must function perfectly.
Although the construction of the sleeve is very sturdy and reliable, it is recommended to verify periodically
that it rotates without friction. If a defect should be present, please contact your local agent.
Chain
It is possible that after a certain amount of use, the drive needs to be tightened.
To tighten the drive, refer to Chapter 7 / Point 6.3.
3.5. Cleaning
As with any vehicle, machinery, or device, regular cleaning of your bar feeder can only serve to improve
its operation and prolong its useful life.
For cleaning on the outside, use a soft cloth and a regular detergent; for the inside, use a cloth or a brush.
However, make sure that the rollers and parts made of synthetic materials do not come into contact with
these products.
Use of compressed air for cleaning is not advisable, because particles could become lodged in sensitive
areas and impede the proper operation of the bar feeder.
At no time should solvents, such as acetone, or diluents be used for cleaning the bar
feeder. At no time should cleaning products come into contact with electrical components.
