Congratulations on your purchase of the GRR-RIPPER 3D PUSHBLOCK system.
We have put a lot of thought and effort into designing and making what we believe
is the safest, most precise pushblock available. Before using your GRR-RIPPER, read
through this booklet to familiarize yourself with the GRR-RIPPER and how it works.
Here is a general overview of the way the GRR-RIPPER was designed to work:
Green GRR-RIP®
• The GRR-RIPPER uses grooved
non-slip pads (Green GRR-RIP®) to
hold down and feed your workpiece
through the cutting element. The tool
can be rotated end-to-end to for use
with either the 1/2” or 1/4” Side Leg
against the fence.
• With the rip fence set parallel to the
saw blade, the GRR-RIPPER glides
against the rip fence to ensure a
parallel feed. It also keeps both sides
of the workpiece in their original
positions throughout the cutting
process, which virtually prevents the
possibility of kickback and burning.
With bare-hand feeding eliminated,
finger injury is greatly reduced.
• The GRR-RIPPER feeds the workpiece
as the saw blade passes through
either its right or left tunnel. This
feature provides protection to both
hands of the user. The GRR-RIPPER is
a protective blade-cover that the user
holds regardless of movement.

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. The user 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 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.
• 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.
• 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.
• 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.
• 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, the user 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.
• 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. The
user should frequently inspect the
effectiveness of the non-slip pads.
Remove built up dust as necessary with
denatured alcohol.
• 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.
• Do not use this tool if any of the
components are damaged. Contact
your dealer or the manufacturer for
replacement parts.
• 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.
• When not in use, store this product on a
flat and clean surface.
• Always wear safety glasses and hearing
protection. Follow all normal shop
safety practices.
• Use saw blades that are designed for
the intended cutting operation.
• When using only one GRR-RIPPER, the
user must have both hands on this tool
- one gripping the handle and the other
on top of the main body.
• The machine tabletop used in
conjunction with this tool must be
flat and free from obstructions other
than the required fence and one
cutting element. The tabletop must be
reasonably level and below the waistline
of the user.

SAFETY BASICS
8
• 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.
• It is the sole responsibility of 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.
• Do not use this product while under
the influence of drugs, alcohol or any
medication.
• To clean this product, use denatured
(available at the paint department of
home improvement centers or rubbing
alcohol (available at drug stores).
• 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 the user is not confident in
making the cut, do not proceed.
IMPORTANT: Never wear loose clothing,
gloves, bracelets or other jewelry that
may get caught in the moving parts or
cutting elements.
TABLE SAW PREPARARTION
• You must have a sturdy and straight rip
fence with a flat front surface preferably
at least 3” in height and square to the
table saw top. The rip fence must be
long enough to cover the entire depth
from the front to the rear of your table
saw top. The rip fence must also be
equipped with a locking mechanism to
secure it on the table saw top so that it
is parallel to the saw blade at all scale
settings. DO NOT SKEW THE
RIP FENCE!
• The rip fence should also be accurately
calibrated to a fixed scale to secure a
precise cutting width setting.
• A sharp and clean carbide-tipped saw
blade should be used with this tool for
ripping, unless otherwise specified.
• A Zero-Clearance Throat Plate or insert
(ZCI) should always be used when
cutting narrow strips. Watch our online
video on how to install a Zero-Clearance

TECHNIQUES TECHNIQUES
12 13
• The GRR-RIPPER 3D PUSHBLOCK
system is designed to glide along the
rip fence of a table saw, so the rip fence
must be parallel to the saw blade in
order to maintain the parallel feed.
• The saw blade should be raised just
enough in height to clear the gullets
from the top surface of wood pieces;
normally about 1/4” to 3/8”. Pay extra
caution on workpieces that are not
equal in thickness such as tapered stock.
The tunnel has a clearance of 15/16”
in height.
• The saw blade must pass through the
adjustable tunnel and in between the
legs for maximum safety. Visually check
the Saw Blade Tunnel before turning
on your saw to make sure that the saw
blade will not cut into any component
of the GRR-RIPPER.
• When using a single GRR-RIPPER, both
hands should be used on the tool. Place
one hand in the inclined position and
grip the Handle (1). Place the other on
the top of the Main Body (2) to provide
added pressure against the rip fence,
additional forward feeding and firm
downward pressure on the workpiece.
WARNING: NEVER feed stock using
bare hands when using the GRR-RIPPER.
• The Handle (1) can be secured at an
angle in relation to the Side Legs (see
Figure 17) an automatic pressure will be
exerted against the fence when the tool
is pushed forward.
• For best cutting results, use one non-
stop feed from start to finish - do not
pause during the cutting operation.
Push the workpiece completely clear
of the saw blade, stop the motor, and
wait for the saw blade to come to a
complete stop before releasing pressure
from the workpiece.
• The non-slip pads are molded from
a thermal plastic that will slightly
compress when downward pressure is
applied. When setting the height of the
Balance Support (6), it is best to set the
non-slip pads over the workpiece, put
normal downward pressure from the
Handle (1), lower the Balance Support
(6) until it fully contacts the table saw
top, then secure the Balance Support
(6) in that position before releasing
pressure from the Handle (1). Double-
check the setup by applying downward
pressure on the tool with one hand and
slightly pulling the workpiece under the
tool. If not enough contact pressure
is either in the front or rear, adjust the
Balance Support (6) accordingly.
• Depending on your table saw model,
the GRR-RIPPER system should be
placed about 1“ to 4” from the trailing
end of the workpiece, otherwise, the
tool will be off the table saw top at the
rear before the workpiece will be clear
of the saw blade.
• If workpiece is longer than 16”, the
use of two GRR-RIPPER systems is
recommended for connecting two
GRR-RIPPERs or use the “leap-frogging”
technique for cutting stock of unlimited
length.
• If the width of the cut is between 1/4”
to 5/8” on the Inside Cut, use the 1/4”
Side Leg (5) on the right against the
rip fence. If the width of the cut is less
than 1/4”, it should be obtained from
Outside Cut as shown in Figure 15 on
Page 16. One advantage of using the
GRR-RIPPER for cutting thin strips over
the conventional push block method
is the width of your prepared stock
on the Inside Cut area is substantially
reduced. Yield is greatly increased by
saving material, thus reducing costs.
Most importantly, the saw blade is
always within the tunnel, which provides
protection for your fingers.
• For a wider Inside Cut that is beyond
the limits of the GRR-RIPPER system,
wooden spacers of various widths can
be added to the Side Leg against the
fence (see Figure 3). You may drill a
couple of counter bored holes (5”
center-to-center) for 10-32
pan head screws and secure it to
the brass inserts on the Side Legs.
Alternately, you can use #8 pan head
wood screws from the inside wall of the
1/2” Side Leg (4).

TECHNIQUES TECHNIQUES
14 15
Using the 1/4” Leg
Use the 1/4” Leg (5) against the fence for
cutting width (Inside Cut) of 1/4” to 5/8”.
Note the location of the Handle (1) above
the cut line in order to apply balanced
pressure to both sides of the stock.
Irregularly Shaped Stock
This is a translucent bottom view with the
table saw top removed for clarity. The
GRR-RIPPER GR-200 is feeding irregularly
shaped stock to obtain a straight
edge. Notice the 1/2” Leg (5) does not
cover the stock edge completely. The
Adjustable Spacer (8) is used with the
smooth side down and leveled with table
top to prevent the tool from tipping over
and to glide against the rip fence for a
parallel feed. Watch the online video:
http://bit.ly/straight-line-ripping
WARNING! Before turning on the saw, always visually check the Saw
Blade Tunnel to make sure this is enough clearance for the saw blade to pass
through safely.
NOTE: All table saw illustrations in this instruction manual show a 1/8” kerf saw
blade and a rip fence that is secured parallel and to the right of the saw blade.
Inside Cut = Cut between rip fence and the saw blade, is usually the keeper piece.
Outside Cut = Cut on the left side of saw blade, is usually the off-cut piece.

stock is not wide enough to be under
the Side Leg on the left. The Handle (1)
is secured more towards the right side of
saw blade since no pressure is required
on the left side of the cut.

Resawing: You can resaw narrow stock in one pass without a band saw,
planer or flat-bed sander. Note: Stock must be square before resawing.
Resawing
Resaw to 1/4” (Inside Cut) or thicker in one
pass as shown in Figure 18. Note Handle (1)
location.
Resawing stock thinner than 1/4”, or resawing
wider stock, can be achieved in two passes
by setting the saw blade slightly higher than
one half of the width of the stock in the first
pass. Flip the stock over and finish with a
second cut.
Suggestion: Resawing stock thinner than 1/4”
should be obtained from the outside cut.
A wooden spacer can be added to the
Balance Support (6) for stock wider than 2”
(see Figure 3).
