Powermatic 201HH operating instructions Maintenance, Lubrication

Never attempt pressure bar adjustment while planer is connected to power.

Feed restriction can also occur due to pitch buildup on the table. Be sure the table surface is clean. Occasionally dusting the surface with talc will aid in smoother feeding and help prevent pitch buildup.

Halted Feeding

If the infeed roller takes the stock, the chipbreakers lift, and just as you hear the knives contact the material, it stops feeding, then the pressure bar is too low. Reset the pressure bar (see page 13).

Maintenance

Periodic inspections are required to ensure that the machine is in proper adjustment, that all screws are tight, that belts are in good condition, that dust has not accumulated in the electrical enclosures, and that there are no loose or worn electrical connections.

Buildup of sawdust and other debris can cause your machine to plane inaccurately. Periodic cleaning is not only recommended but mandatory for accurate planing.

Close-fitting parts, such as the table locking rods, the cutterhead slot and gibs, should be cleaned with a cloth or brush and non- flammable solvent and freed from clinging foreign matter.

Use caution and proceed slowly when working with or around the cutterhead knives.

Remove resin and other accumulations from feed rolls and table with a non-flammable solvent.

Periodically check all the chains and belts for proper tension and adjust accordingly if required.

TIP: If a foreign object nicks the knives on the straight cutterhead (Model 201), instead of throwing them away or trying to grind out the deep nick, simply stagger the knives in the head, moving one knife no more than 1/4” to the right and another knife no more than 1/4” to the left. The nick will not be noticeable.

Lubrication

The gear box oil should be changed at least once a year. Remove the drain plug (A, Figure

25)to drain the oil into an appropriate container. Replace the drain plug and fill the gear box with 60 to 90 weight gear oil through the fill hole (B, Figure 25). The sight glass (C, Figure 25) should be checked periodically and oil topped off as necessary.

The recommended lubrication for roller chains used in medium to slow speed operation is to simply wipe the chain clean. When there is an appreciable buildup of dust, dirt or wood shavings, use an oil cloth but never pour the oil directly on the chain. Over-oiling defeats the purpose of the lubrication, since it tends to invite the collection of dust, shavings, etc. and works into members of the chain. This hastens wear and leads to premature replacement.

The bearings on the cutterhead and feed rollers are factory lubricated and sealed. They require no further attention.
