NOTE! The bar’s groove depth must be sufficient for the chain’s straps and cutters to ride on the bar’s rails without drive links touching the bottom of the groove

Remove any imbedded particles or debris from the groove

If wear on the saw bar is beyond limits, chain sprocket pitch and alignment must be corrected

See “Inspect Sprocket Pitch Wear” for correction procedure

Pressure reducing valve sets pressure on the cylinder base end flow control valve

This valve controls saw up pressure and is factory set to 750 PSI

Pressure reducing valve should be adjusted by an authorized dealer

Counter-balance valve sets pressure on the cylinder rod end flow control valve

This valve controls saw down pressure and should be set to 600 PSI

Oil filled to the bottom of the filler neck?

Checked the level more often than the prescribed 8 hour interval if saw use is heavy?

If the reservoir runs dry, manually applied oil to the stopped chain?

Refilled the reservoir and “primed” the oiler by cycling the bar up and down at least ten times?

NOTE! Use BIO-HY-GARD oil or an equivalent “All Season” high quality bio-degradable oil such as John Deere UP08142 Bar and Chain Oil;
