iso 32 equivalent. the fill cap is located on top
of the headstock. the drain plug and sight glass

three-to-four hours of use. see figure 41.
Lubricant
End Gears: Apply a thin coating of grease to the
end gears. Avoid applying excess grease to the
gears. Apply one squirt of iso 32 oil into the port
shown in figure 42.
Note: Problems can occur if excess grease is
flung onto the V-belts during operation, causing
a loss of power from the belts slipping on the pul-
leys. If this happens, remove and discard the con-
taminated V-belts, clean the pulleys with mineral
spirits or solvent, and install new V-belts.
