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 .
