PX|12 Quadtec:I Planer \ Maintenance
Figure 16: Under view of planer showing chain
configuration.
The chain tension for carriage adjustment was established at the factory. When the chain stretches from
normal use it may require tensioning. Excessive play in the thickness adjustment handle indicates a
potentially loose chain.
1. Disconnect Power to planer.
2. Lay planer on its front side.
3. Test tension by compressing chain between sprockets. It should deflect approximately 3/8”. If it
compresses more, continue with the next steps.
4. To adjust tension, loosen the socket head hex cap screw in the center of chain tension arm (Fig. 16).
NOTE:
Do not allow the chain to fall from the sprockets when loosening the tension bracket as this would
require recalibrating the raising mechanism.
5. Rotate tension bracket to establish proper tension (the chain deflecting approximately 3/8” when
compressed between sprockets).
NOTE:
Over tension will result in difficult thickness adjustment cranking.
6. Tighten the socket head hex cap screw in the center of chain tension arm.
Dust Collection
To ensure proper operation and longest knife life it is important to maintain full air flow to your dust
collection system. Make sure the filter media is clean and there are no obstructions in the ducting.
