6.2 Work area:

The work area is at the front of the machine (fig.3, n°15).

English

6.3 Safety features:

This machine is equipped with:

A lever that operates machine start-up and bread slicing. Releasing the lever causes the machine to stop.

A safety cut-out that prevents the machine from operating if the front table on a Misch type machine is in the open position (fig.11, n°22).

A safety cut-out that prevents the machine from operating if the cover (for machines fitted with a rear cover) is open (fig.13, n°27).

7 OPERATION

Braked castors must be locked while the machine is in operation (flg.1, n°11).

Switch on the power to the machine at the start of the day using the emergency stop (fig.1, n°10).

After switching on using the emergency stop and if your machine is fitted with a Misch lubrication system (BEF - BEM) the knife start button (fig.2, n°14) must be pressed in order to release the loaf pusher from the blades.

Operating procedure (fig.4)

A. Pull the lever towards you. If your machine is fitted with a rear cover (optional) (BEG - BEG ETL - BET), the cover will open automatically when the lever is operated.
B. While pulling and holding the lever, place the loaf on the rear table (fig.3, n°14), between the blades and the moving section.
C. Release the lever gently. This action will cause the loaf to be pushed through the blades. Retrieve your sliced loaf once the lever has returned fully to its released position.

At the end of the day, press the red emergency stop button (fig.1, n°10) to switch the power off to the machine.

Tip: Have a qualified individual check blade tension after the first few days of operation.

Capacity: Number of loaves sliced per day: 6,000 (depending on the type of bread). Loaf size (L x W x H) (cm):

12 x 6 x 6 min. - 44 x 31 x 16 max. (on 450 wide slicers)
12 x 6 x 6 min. - 58 x 31 x 16 max. (on 600 wide slicers)

8 MAINTENANCE

8.1 Daily, by a trained operator.

A. Check whether you need to empty the crumb tray (fig.1, n°7).
B. Clean the tables (fig.1, n°6) (fig.3, n°14) using a brush.
C. Use a dry cloth to clean the inside.
D. Use a damp cloth to clean the outside.

English

8.2 Every 25,000 loaves and/or at least once a year, by an approved agent.
