Changing Oil & Flushing Reservoir
Small metal particles may accumulate at the bot-
tom of the reservoir with normal use. Therefore,
to keep the reservoir clean, drain and flush it after
the first 300 hours, then after every 1000 hours.
Place a catch pan under the apron drain plug
shown in Figure 119, then use a 24mm open-end
wrench to remove the fill plug and drain plug, then
empty the reservoir.
Flush the reservoir by pouring a small amount of
clean oil into the fill hole and allowing it to drain
out the bottom. Replace the drain plug, add oil as
previously described, then re-install the fill plug.

Ball Oilers
Proper lubrication of ball oilers is done with a
pump-type oil can that has a plastic or rubber-
ized cone tip. We do not recommend using metal
needle or lance tips, as they can push the ball too

far into the oiler, break the spring seat, and lodge
the ball in the oil galley.
Sight
Glass Lubricate the ball oilers before and after machine
use, and more frequently under heavy use. When
lubricating ball oilers, first clean the outside sur-
face to remove any dust or grime. Push the rub-
ber or plastic tip of the oil can nozzle against the
ball oiler to create a hydraulic seal, then pump the
oil can once or twice. If you see sludge and con-
taminants coming out of the lubrication area, keep
pumping the oil can until the oil runs clear. When
finished, wipe away any excess oil.
