Inspect and track the follower belt
WHAT YOU NEED
Tools:Allen Key SetLarge Flat Head Screwdriver
Safety Equipment:Standard Personal Protective Equipment
Inspection
- Isolate the saw electrically.
- Remove the follower top guard.
- Disconnect the follower power cable from the follower servo drive in the electrical cabinet.
-
Manually push the follower slowly the whole length of the rail in both directions while visually inspecting the follower belt tracking on the drive pulley.
Note: The belt should not rub on any part of the follower assembly. The belt may float on the drive pulley as long as it does not come within 2 mm of touching any adjacent part.
- If the tracking needs to be adjusted, follow the procedure below.
Tracking
Note: The tracking is influenced by the idle roller leading the direction of travel:When the follower is moving towards the saw chamber, adjust the idle roller closest to the saw chamber.When the follower is moving away from the saw chamber, adjust the idle roller farthest from the saw chamber.
- For the direction requiring tracking, slightly loosen the mounting bolt on one side of the relevant idle roller.
- Using a large flat head screwdriver on the same side as the loosened mounting bolt, lever the roller in the desired direction to adjust its orientation.
-
While holding the roller in the desired position with the screwdriver, re-tighten the roller mounting bolt.
Note: Only a very fine adjustment is required. Moving the mounting position by a fraction of a millimetre may make a large difference.
- Manually push the follower up and down the rail to check the belt tracking.
- Repeat the tracking procedure if needed.
Testing
- Reconnect the follower power cable onto the follower servo drive in the electrical cabinet.
- Turn on the electrical isolation switch on the front of the saw.
- Rehome the saw 3 to 4 times with the follower top guard off. While standing clear, make sure the follower belt tracks correctly on the drive pulley.
- Feed 2 to 3 boards into the saw with the follower top guard off. While standing clear, make sure the follower belt still tracks correctly on the drive pulley.
- Press the E‑stop button on the operator console.
- Refit the follower top guard.
