1.9 Cleaning the Nozzle Shaft (Every 1000 Hours)

Point

Dust and particles that cling to the nozzle shaft have a negative influence on placement.

Therefore, the nozzle shaft should be cleaned every 1000 hours.

To carry out nozzle shaft maintenance, a special spanner is required.

Procedure

WARNING

Always be sure to cut the main power before carrying out

any work.

1. Remove the nozzle holder from the turret.

2. Insert the spanner at the lower end of the shaft and loosen the bolt.

Notes:

1. The shaft may be damaged if the spanner is not used carefully when loosening the bolt.

2. Remove the bolt in such a way that the bearing is not propelled from its socket due to

the spring’s pressure.

3. Clean the surface of the shaft using a dry cloth, and reapply lubricant.

Specified lubricant: EVERS-2

4. When reassembling the shaft, apply Locktite 222 to the screw of the bolt, and use

the special spanner to attach the shaft, tightening it to a torque of 2 N·m

(20 kgf·cm).

Note: Ensure the Locktite 222 does not come into contact with the bearings.

5. Attach the nozzle holder to the unit.

1.10 Cleaning the Y-axis Motor Cooling Fan Filter

(Monthly)

Point

A cooling fan is attached to the Y-axis motor. As the machine is operated, dust collects in

the filter of this fan, reducing the cooling effect on the motor. These filters must therefore

be cleaned regularly.

Procedure

Remove the filter cover, then the filter from the motor. Clean the filter using a neutral

detergent, and reattach it to the motor when it is dry.

Replace the filter if it is damaged or has collected too much dust.
