SAFETY WARNING! Operation of the GRR-RIPPER 3D Pushblock system
includes the use of a table saw or other tools that are not part of the GRR-RIPPER.
Micro Jig, Inc. assumes no liability for any product not sold and manufactured by
Micro Jig, Inc. You must take all necessary precautions when operating a table
saw or other tools as recommended by their manufacturers or as required by any
prudent tool user. You must also read and agree to the safety precautions and terms
listed below before using the GRR-RIPPER 3D Pushblock system. Your assembly of
the GRR-RIPPER 3D Pushblock system indicates your agreement to follow these
safety precautions and terms when using this tool.
The GRR-RIPPER 3D Pushblock System
includes three legs with non-slip pads.
A minimum of two legs MUST be
installed during any cutting operation.
Use at least one leg to the right and
one leg to the left of the saw blade
whenever possible.
Before every cut, you must look
through from the end of the tool after
it is in an operational position to make
sure the cutter will go through the
tunnel between the legs throughout
the entire cutting operation, without
touching any component of the tool or
other objects except the workpiece.
The bottom of the workpiece must be
flat enough so that it does not rock on
the table top. The top of the workpiece
must be flat enough so all non-slip
surfaces are in full contact with the top
surface of the workpiece.
In table saw operation, the face of the
Side Leg on the right must be in full
contact with the rip fence at all times
in order to create a parallel guide for
forward feeding and inward pressure
against the rip fence.
The saw blade must not be set more
than 3/4” higher than the top surface
of a flat workpiece. The ideal height is
when the top gullet is slightly above the
top surface of the workpiece.
All components must be inspected for
damage and securely fastened before
every use. Stop using the tool if any
damage occurs.
In table saw operations, the rip fence
must be securely locked parallel to
the saw blade within the usable range
of the GRR-RIPPER 3D Pushblock
system.
When using this tool in conjunction with
any other tool, first read and follow all
instructions and safety information in
the owner’s manual for that tool.
Always wear safety glasses and hearing
protection. Follow all normal shop
safety practices.
It is the sole responsibility of the
purchaser of this product to ensure that
any third party reads and agrees to all
safety precautions and terms prior to
their use of this tool.
In table saw operations, the GRR-
RIPPER 3D Pushblock system must be
used so it is in full contact with the rip
fence at all times, and the saw blade
MUST pass through and within the
tunnel between two of the legs.
Use maximum possible coverage of the
non-slip pads on the workpiece.
The GRR-RIPPER 3D Pushblock system
must be used in an absolute stable
condition. When a workpiece is narrow
and is not covered by the leg on the
left (away from fence), the Balance
Support must be secured to the left leg
so the bottom surface of the Balance
Support is in full contact with the table
top to secure the steadiness of the tool
during the entire cutting operation.
The non-slip pads placed on the top
surface of the workpiece must be in
full contact with the workpiece.
Frequently inspect the effectiveness
of the non-slip pads. Remove built-up
dust as necessary with denatured or
rubbing alcohol.
When using only one GRR-RIPPER, you
must have both hands on this tool - one
gripping the handle and the other on
top of the main body.
When cutting small stock or irregular-
shaped workpieces, please ensure the
Balance Support and Adjustable Spacer
are securely supporting the GRR-
RIPPER to prevent any type of tilting.
See Figure 16. If the GRR-RIPPER
does not appear stable or you are not
confident in making the cut, do
not proceed.
Use saw blades that are designed for
the intended cutting operation.
