When replacing oiler brushes into brush holders, use regular 1/2"-20 nuts.
Tighten nut finger tight initially as some adjustment may be needed later. For
best results, place brush holders over top of roller chains and directly on top of
sprockets. Adjust brush holders so oiler brushes are pushed down into the
roller chain approximately 1/2". Carefully tighten up the 1/2"-20 nuts on the
oiler brushes. DO NOT over tighten as damage to the brush will occur. The
plastic threads of the oiler brush will crack and then break off from the brush
body.
IMPORTANT! The 5/32" oil line
tubing can only be removed from
an oiler brush by pushing in on
the red plastic ring and pulling the
tubing out while holding the ring
down.
The oiler pump is set at the factory to
deliver the maximum amount of oil
per cycle. If less oil is desired, loosen
the jam nut on the bottom of the
pump and screw in the adjusting shaft 1/4" or approximately 5 turns.
It is not recommended to screw the shaft into the bottom of the oiler
pump more than 15 turns as this may not allow for proper lubrication
of the roller chains.
IMPORTANT! Always use new 30 weight oil. In cold weather,
use a SAE 10 or a mixture of two parts of 30 weight oil to one
part diesel fuel.
