Grizzly Expert Tips for Adjusting Feed Roller Speed on Planers

Feed Roller Speed

The infeed and outfeed rollers power the stock through the planer. They keep boards flat and provide smooth movement. The power feed fea- tures two feed rates - 16 FPM and 20 FPM. The speed can be changed by moving the feed con- trol knob when the machine is running. See Figure 15. Moving the knob toward the machine (Pos B) produces the 20 FPM feed speed, away from the machine (Pos D) produces 16 FPM and a center position (Pos C) places the gearbox in neutral.

NOTICE

The feed rate must be set before feeding lumber into the planer. DO NOT attempt to change speeds after the planing operation has begun. Damage to the gearbox will result.

Roller Adjustment

The infeed and outfeed rollers must be set at

.040" below the level of the cutting edge of the knives. To set the height of the infeed and out- feed rollers:

1.Disconnect the planer from its power source.

2.Make sure the knives are set correctly.

3.Remove the chain cover. Refer to the pre- run check for removal instruction.

4.Loosen the cap screw that holds the static chain tensioner and swing the tensioner out of the way. See Figure 16.

5.Place Block ''A'' under the cutterhead with a

.040'' feeler gauge above it and raise the table until the block reaches the cutterhead. Center one of the knives at the bottom of the cutterhead as you raise the table. Rock the cutterhead backward and forward as you raise the table and stop when the knife just touches the feeler gauge. See Figure 17.

6.The table is now positioned correctly. Lock the table in place.

7.Remove the feeler gauge and move the block to the right end of the infeed drive roller.
