Feed Control Adjustments
Connect and Cut saw systems have a control manifold with cartridge valves to limit flow to the saw motor and feed
cylinder, and a feed modulating valve to adjust the feed speed based on the saw motor pressure. We have tested
the operation of your system to set the valves before shipping so your system should cut any diameter, species, or
hardness of wood without stalling the chain in the cut. The feed modulating valve will make the bar pulsate in the
cut on larger or harder wood as it is trying to cut as fast as possible. It may be possible to fine tune the cutting for
your application by adjusting the saw feed speed adjustment valve (Fig. 8, item 11). For larger or harder wood
loosen the jam nut with a 9/16” wrench and screw the adjustment screw out with a 5/32” hex key wrench (Allen
wrench), this will slow the bar movement down, lock the jam nut down when done adjusting. For smaller softer
wood you may want to speed up the bar movement by screwing the adjustment screw in. Having the bar move too
fast may cause the chain to stick when starting into the cut if the chain hits a knot. It is possible to tune the feed
modulating valve (Fig. 8, item 2) by loosening the jam nut with a 9/16” wrench and adjusting the screw with a 3/16”
hex key. A smoother cut may be possible by screwing the adjustment screw out, but this may increase the cutting
time in larger or harder wood. If the wood is dry and hard screwing the feed modulating adjustment in may decrease
cutting time. Screwing the feed modulating adjustment in too far will cause the chain to stall. Be sure to lock the jam
nut after adjusting a valve.
