Opening Hood

To open the hood for access to the cutterhead, remove the two hex screws with the 22mm wrench provided. See Figure 6.

KNIFE INSTALLATION & ADJUSTMENT

CAUTION: Use care when placing hands near knives as they are extremely sharp and can cause severe cuts.

Installing knives on a planer is an exacting process. If the knives are not to be jointed and ground, end-to-end and knife-to-knife relationship must be held within .001" (.03mm) for accurate and smooth planing. To help avoid cutterhead distortion in changing out a set of knives, remove and replace the knife in one slot before changing the next knife.

Any knife adjustment or replacement should be done to all four knives at the same time. Failure to do this may result in an out-of-balance cutterhead which can lead to bearing failure.

1.Disconnect machine from power source.

2.To remove knife, loosen the six hex head screws. See Figure 7.

3.The knife is spring loaded and will rise up in the slot. Carefully remove knife from cutterhead by lifting straight out. Remove gib and springs, and clean any dust, pitch or accumulated foreign matter from the slot and the gib.

4.Replace the springs and gib into the slot, then insert new knife and loosely snug the six hex head screws.

5.Carefully place the knife-setting gauge until it contacts the cutterhead, as shown in Figure 8. This will hold the high point of the knives to the proper height above the cutterhead (approximately 1/8” or 3.18mm). Use the gauge at both ends of the knife, then check the center section to be sure it is even. If it is low, try backing off slightly on the center gib screw to allow blade to come up. Gently tap blade down with piece of wood until it conforms to the gauge height. Recheck the full length of the knife.

NOTE: If all knives have been removed, a new set must be installed with the gib screws lightly snugged down but not fully tightened. All knives and gibs should be in place before tightening. Locking one knife in without the others in position can cause cutterhead distortion. The tightening process should proceed working from the center out on each knife and after locking all gib screws once, repeat the same sequence until all screws are equally tight.
