Lubrication

Wipe off all sawdust and abrasives from grease fittings
and plugs before lubrication. When lubricating machine
parts, your goal is to achieve adequate lubrication to
prevent rust, and a thin layer of lubricant to prevent
metal-to-metalfriction.Toomuchlubricationwill
attract dirt and sawdust, causing machine parts to bind.
•Afterthe first300hoursofuse,replace thegear
reducer (Figure 29) lubricant with straight 140W
gear oil (available at most automotive parts stores)
uptothecenterofthesightglass. DONOTusethe

low and oil can leak past seals.
•After2,500 hoursofusethereafter,replacethe
gear lube and always clean the vented plug (Figure
29) to make sure it vents the gear case.
•Afterevery 150hoursofuse,lubricatethe bearings
(Figure 30 & 31)withonesquirtof automotive-
grade grease at the designated points.

elevation screws with grease, and brush or lightly
spray the table chain and sprockets with a light
coat of oil and wipe any drips off (see Figure 31).
