I have a General International model 30-300. It has been a wonderful piece of machinery.Recently while planing the shavings would pile up and leave dimples in the lumber where the shavings are building up. The pine lumber is dry, it is 2”X12”. I have put in newly sharpened blades. adjusted the shoot to the dust collector, as low as possible, adjusted the orange plastic insert after the blades as far away from blades as possible. This worked perfect for 10 boards and has started to jam again. I have adjusted the above mentioned adjustments numerous times and still am having problems. Does anyone have any insight as to what the problem could be? Thanks for any input.

Welcome to LJ

Problems that create dimples during planing on woods surface are the shavings pressed into the wood by the outfeed roller. This can be caused by:

Dust Collector
Clogged Inlet. Inlet at dust collector near impeller blade usually has a device to stop large wood chips from entering and damaging impeller blade(s). This needs to be inspected with power cord disconnected.
Not enough Cubic Feet per Minute (CFM) of air movement to carry the chip load do to size of collectors motor, speed or hose.
Impeller slipping on motor shaft
Reduced vacuum at collector because of air leaks at bags, hose etc.

Hose between machine and collector
Hose is kinked or has sever angles reducing velocity of air flow thus causing shaving buildup (clogging).
Diameter to small
Hose to long
Leaks at hose to equipment connection.
Leaks in hose

D.C. filter clogged? Removing too much material per pass? Type of lumber plays a role too. For me maple is the most likely to clog due to curly shavings.
