Troubleshooting

9.2.2Suction

Check the suction system daily to ensure that it is func-
tioning properly. If the suction does not work or only 
works to a limited extent, it must be repaired. Only then 
may the surface planer and thicknesser be put into ope-
ration.

9.2.3Lubrication

The surface/thickness planer is low maintenance. The 
ball bearings are permanently lubricated. After approx. 
ten operating hours, relubrication of the following parts is 
recommended: 

- Bearing arrangement of the infeed and outfeed 
  roller

- Bearing of belt pulley and sprocket

The threaded spindle for height adjustment of the thick-
nessing table must only be treated with dry lubricant. The 
table surfaces and the infeed and outfeed rollers must al-
ways be kept free of resin. 

9.2.4 Regular inspection of the planing knives

Check the blades of the planing knives regularly, as most 
problems occur when planing due to dull knives.

9.2.5Changing the drive belt

The drive belt must not come into contact with oil or 
grease. It must be checked regularly for wear, cracks or 
brittleness. Replace the drive belt if necessary, at least 
once a year.
