Before you begin any jointer operation turn on the Mark V, set the speed dial according to Table 6-1, and let the jointer come up to speed
The deeper the cut or the harder the wood, the slower you should run the jointer. If the jointer runs too slow, you may get a rough cut, so you'll want to experiment with scrap until you can select the proper speed for the stock you're jointing.
Table 6-1: Jointer Speed Chart
M (3900 RPM)
O (4550 RPM)
Q (5300 RPM)
S (6200 RPM)
Note: These speeds are for 60 hz. operations. Because the Jointer mounts on the lower auxiliary spindle, the rpm is 1.6 times faster than for the upper auxiliary and main spindles.
