The Power Beyond Port can connect to another valve for conveyor and clamp, or must go to the filter and tank. The 
return hose can be #8 or 1/2” diameter for the first five feet. If a longer hose is required it must be #12 or 3/4” up to 
thirty feet. If the total return hose length is greater than thirty three feet #26 or 1” hose should be used. The filter 
must be rated for 10 GPM plus any additional pump flowing into it. The saw motor should run between 4000 RPM 
and 5500 RPM. At this speed the pressure at the return to filter connection should not exceed 80 psi when the saw 
motor is running. We do not recommend using quick disconnects but if you choose to use quick disconnects in the 
tank line, first consult the manufacture to determine the correct size to keep the back pressure low enough in cold 
temperatures. Failure to properly size the hose and filter or properly connect the return hose to a filter and tank will 
shorten the motor shaft seal life and will not be covered by warranty. 

Chain Tension and Sharpening 

Figure 5 shows the chain tensioning screw. A #2 or #3 Phillips screwdriver is required to turn the tension screw. With 
the supplied saw bar, correct tension is when the cutters come off the rails roughly 1/8” with a tug of finger 
pressure. Refer to the Oregon Mechanical Timber Harvesting Handbook for more tensioning information and 
sharpening information.
