SAFETY BASICS SAFETY BASICS 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.
ASSEMBLY SAFETY BASICS • 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.
ASSEMBLY ASSEMBLY STEP 5 IMPORTANT: Brass Inserts 9 A x2 E x2 6 Balance Support C x2 Attach Thumb Screws (E) to Balance Support (6).

Repeat cleaning during use as necessary when saw dust accumulates.
TECHNIQUES TECHNIQUES • 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. •T he 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.
TECHNIQUES TECHNIQUES 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.
