Leveling & Mounting; Leveling; Bolting To Concrete Floors; Machine Mounts - Grizzly G0747 Owner's Manual

Leveling & Mounting
generally, you can either bolt your machine to the
floor or mount it on machine mounts. Although
not required, we recommend that you secure the
machine to the floor and level it while doing so.
Because this is an optional step and floor materi-
als may vary, hardware for securing the machine
to the floor is not included.
Unless otherwise specified by your local
codes, this machine MUST be secured to
the floor if it is permanently connected
(hardwired) to the power supply.

Leveling

leveling machinery helps precision components,
such as dovetail ways, remain straight and flat
during the lifespan of the machine. Components
on an unleveled machine may slowly twist due to
the dynamic loads placed on the machine during
operation.
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 Figure 7 for an example of a high precision
level available from grizzly.

bolting to Concrete Floors

Anchor studs and lag shield anchors with lag
screw (Figure 8) are two popular methods for
anchoring an object to a concrete floor. We sug-
gest you research the many options and methods
for mounting your machine and choose the best
that fits your specific application

Machine Mounts

Machine mounts (see Figure 9 for an example)
provide the advantage of fast leveling and vibra-
tion reduction. the large size of the foot pads
distributes the weight of the machine to reduce
strain on the floor.
