5.13 Power Feed
1. Adjust the power feed chain as needed. Measure the power feed chain tension with the
saw head all the way toward the front of the mill. Use the adjustment nut on the feed ten-
sioner at the front of the mill to tighten or loosen the power feed chain. Adjust the chain
until it measures 7 to 8 inches (17.8 to 20.3 cm) from the top of the top rail at its lowest
point.
CAUTION! Do not overtighten the feed chain. Damage to
the gear reducer may result.
See Figure 5-6.
2. Inspect the power feed motor brushes every 750 hours of operation. Remove brush dust
and replace the brushes if they worn to a length of 5/8” or shorter.
CAUTION! Do not operate the power feed system if the
feed motor brushes are worn shorter than 5/8”. Damage to
the feed motor may result.
3. Check the power feed gearbox oil level. Add a synthetic gear oil such as Mobil SHC 634
as needed.
Drain and refill the gearbox with 25 ounces of oil after every 5000 hours of sawmill opera-
tion or once a year, whichever comes first.
Wood-Mizer offers replacement gear oil in 8 ounce bottles.
