5 Maintenance

5.1 Sharpening the Blade

Caution! Danger of injury!

Rotating blade can sever fingers! Only sharpen the blade with the sharpener provided. The sharpener has been adjusted for this machine and must be used for this machine only.

The machine number and the number on the sharpening device are identical. The blade may only be sharpened by personnel who have been trained to do so.

Caution! Danger of injury!

The carriage drive must be unlocked before "sharpening" for preventing the carriage drive to be switched on accidentally during sharpening of the blades.

5.1.1. Description of the Blade Sharpener

5.1.2. Preparing the Machine

• Thoroughly clean the machine and the blade.
- Remove the guide rail and the blade cover plate.
- Put the last slice clamp down on the carriage.
- Push the carriage about 5 cm towards the blade.
- Turn the slice thickness control for the slice thickness to the "S" marking for sharpening.

5.1.3. Sharpening the Blade

Close-up of hands holding a black handheld device with orange arrows indicating direction (no text or symbols visible)

- Set the blade sharpener to position "0" using the adjusting knob.

• Put the blade sharpener on the limit stop.
• Both clamp arms (1) must touch the stop edge at the top.
• Push the sharpener towards the blade until the bolt head (2) touches the blade ring.
• Place the blade sharpener with the thumb wheel on the limit stop.

! IMPORTANT!

The blade can only be sharpened accurately if the sharpener is positioned exactly.

• Switch on the machine with the green on button.
• Turn the adjusting knob to the grinding position "1".
• Grinding begins.
• The duration of grinding depends on the condition of the blade.

	Grind until a slight cutting ridge is formed.Switch off the machine with the red Off button.Slide a sharpened pencil slowly to the cutting edge as illustrated.Do you feel any resistance at the blade cutting edge? That is the cutting ridge produced from sharpening.If there is no cutting ridge, repeat the steps described above.
	If a cutting ridge has formed on the blade edge, turn the adjusting knob to the deburring position 2.Allow the machine to run for a few revolutions (2-3 seconds) until the ridge is removed.After deburring, switch off the machine with the red Off button.
	Taking off the blade sharpener:Turn the adjusting knob of the blade sharpener to position "0".IMPORTANT!The blade sharpener may only be taken off in this position. Otherwise the blade and the sharpener could be damaged!Undo the knurled screw on the blade sharpener and carefully lift it off.Turn the slice thickness control as far as it will go in a clockwise direction.Clean the blade and the machine.Put the detached blade cover plate and guide rail back on the machine.

5.2 Changing the Blade

WARNING!

The blade is sharp! It can cause serious injury even when it is not moving. The blade may only be replaced by authorised GRAEF service personnel.

CAUTION!
