Leveling
For accurate turning results and to prevent
warping the cast iron bed and ways, the
lathe bedways MUST be leveled from side
to side and from front to back on both ends.
Re-check the bedways 24 hours after
installation, two weeks after that, and then
annually to make sure they remain level.
Leveling machinery helps precision components,
such as bedways, remain straight and flat during
the lifespan of the machine. Components on a
machine that is not level may slowly twist due to
the dynamic loads placed on the machine during
operation.
IMPORTANT: Use only hand tools to secure
machine to floor. Do not tighten with impact tools,
which can permanently twist and bend compo-
nents and pull a level machine out of alignment.
If needed, use metal shims between the lathe bed
and chip pan when leveling the machine.
For best results, use a precision level that is at
least 12" long and sensitive enough to show a
distinct movement when a 0.003" shim (approxi-
mately the thickness of one sheet of standard
newspaper) is placed under one end of the level.
See the figure below for an example of a high
precision level offered by Grizzly.

Lubricating Lathe
GEARBOXES MUST
BE FILLED WITH OIL!
LATHE MAY NOT
HAVE OIL INCLUDED!
Refer to the Lubrication
Section in this Manual
for Recommended
Oil Type.
The headstock, quick-change gearbox, and apron
oil reservoirs must have the proper amount of oil
in them before the lathe can be operated.
Damage caused to the bearings and gears from
running the lathe without oil in the reservoirs
will not be covered under warranty. Refer to the
Lubrication section, beginning on Page 60, for
checking and adding oil.
In addition to the reservoirs, we also recommend
that you lubricate all other points on the machine
at this time. To do this, follow the steps provided in
the maintenance schedule on Page 59.
Note: If this lathe was shipped with oil in the res-
ervoirs, do not change that oil until after the test
run and spindle break-in procedures.
