Grizzly G1033X owner manual Chain Tension, Table Parallelism, To adjust the chain tension

Chain Tension
Tools Needed:	Qty
Phillips Screwdriver #2	1
Wrench or Socket 14mm	1

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 is loosened during table leveling procedures.

To adjust the chain tension:

1.Disconnect the planer from the power source!

2.Remove the motor access panel.

NOTICE

During the next step, DO NOT let the chain fall off the sprockets—returning it to its proper location without changing the table adjustments can be very difficult.

3.Loosen the two lock bolts and move the idler sprocket against the chain to tighten it (Figure 27).

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 side-to-side, as illustrated in Figure 28.
