The chain drive transfers movement from the handwheel to elevate the table. The chain drive can be adjusted to remove slack if the chain stretches over time or during table leveling pro- cedures.
To adjust the chain tension:
1.DISCONNECT THE PLANER FROM THE POWER SOURCE!
2.Remove the motor access panel.
3.Loosen the two locking bolts and move the idler sprocket until chain play has been elimi- nated (Figure 24).

4.Re-tighten the two locking bolts.
5.Check chain lubrication. Refer to SECTION 6: MAINTENANCE on Page 22 for further details.

Table Parallelism
Maximum Allowable Tolerances: |
|
Cutterhead/Table | 0.002" |
Head Casting/Table Front/Back | 0.020" |
Table parallelism is critical to the operation of the machine. As such, it is essential that the table is parallel with the cutterhead (within 0.002") from

Figure 25. Side-to-side parallelism of table and
cutterhead.
How the table sits in relation to the head casting from front-to-back is also important (see Figure 26). Because the feed rollers, pressure bar, and chip breaker will be adjusted off the table position, the tolerances on the front-to-back positioning are not as critical as the cutterhead/table side-to-side positioning. Therefore, the maximum allowable tolerance for the front-to-back parallelism is not more than 0.020".
