SUPER Cabmaker GP8 SAFETY MAINTAIN TOOLS WITH CARE Keep tools clean for the best and safest performance. Always follow maintenance instructions for lubricating and when changing accessories. KEEP WORK AREA CLEAN Cluttered work areas and benches invite accidents. DO NOT USE IN DANGEROUS OR HAZARDOUS ENVIRONMENTS Do not operate equipment in dangerous or hazardous environments. Do not use power tools in damp or wet locations nor expose them to rain. Always keep the work area well lighted.
SUPER Cabmaker GP8 SAFETY NEVER LEAVE A TOOL RUNNING UNATTENDED – TURN POWER OFF Do not leave a tool until it comes to a complete stop. Always turn the tool off, and disconnect the power cord from its source. Do not leave extension cords attached to the power cord or power receptacle (wall outlet) when leaving the work area.

SUPER Cabmaker GP8 SAFETY SILICA DUST WARNING Grinding/cutting/drilling of masonry, concrete, metal and other materials with silica in their composition may give off dust or mists containing crystalline silica. Silica is a basic component of sand, quartz, brick clay, granite and numerous other minerals and rocks. Repeated and/or substantial inhalation of airborne crystalline silica can cause serious or fatal respiratory diseases, including silicosis.
SUPER Cabmaker GP8 SAFETY ELECTRICAL REQUIREMENTS AND GROUNDING INSTRUCTIONS In order to prevent potential electrical shock and injury, the following electrical safety precautions and symbols should be followed at all times! In case of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding conductor and a grounding plug.
SUPER Cabmaker GP8 SAFETY ELECTRICAL REQUIREMENTS AND GROUNDING INSTRUCTIONS To avoid the possibility of the appliance plug or receptacle getting wet, position the tool to one side of a wall mounted receptacle. This will prevent water from dripping onto the receptacle or plug. A “drip loop," shown in illustration below, should be arranged by the user to properly position the power cord relative to the power source.

SUPER Cabmaker GP8 setup CONTENTS In the shipping crate, you will find one Barranca Diamond GP-8 Super Cabmaker mounted to a plastic baseboard and one Ground Fault Circuit Interrupter (GFCI). The accessories for the GP-8 Super Cabmaker will be included depending on which option you choose (see page 10). UNPACKING Your GP-8 Super Cabmaker has been shipped from the factory thoroughly inspected and tested.
SUPER Cabmaker GP8 OPERATION AND ADJUSTMENT PRE-START Check all four motor mount bolts (Fig 3) to make sure they are tight. Fig 1 - Front motor mount bolts Fig 2 - GFCI START-UP Place the GP-8 Super Cabmaker on a strong flat table or bench. A power test can now be conducted to make sure the motor is operating and all moving wheels and blades are correctly aligned and secured to the main shaft.
SUPER Cabmaker GP8 OPERATION AND ADJUSTMENT The GP-8 Super Cabmaker is now ready for a power up test to be performed. Turn the lever to the ON position (Fig 5) on the switch box. Make sure no unusual sounds or vibrations occur when the motor engages. If the motor coupling should loosen, use an allen wrench to tighten the set screws. Liquid thread locker (removable type) can be used on the setscrew threads to prevent loosening during use.
SUPER Cabmaker GP8 OPERATION AND ADJUSTMENT NEEDLE VALVES The three stainless needle valves (Fig 9) are for fine control of water to each of the three grinding and polishing stations. For best results, close the valves to the stations not in use. To shut off flow to a needle valve, simply turn the grey ribbed knob clockwise until it closes to a firm stop (do not overtighten). To open maximum flow to a needle valve, simply turn the grey ribbed knob counterclockwise until the valve stops.
SUPER Cabmaker GP8 OPERATION AND ADJUSTMENT mount can be adjusted by loosening the positioning bolt (Fig 12), moving the tool rest to the desired height, angle and/or distance from the wheel, and then retightening the positioning bolt. The tool rest can also be completely removed (Fig 13) from the GP-8 Super Cabmaker base if the operator so desires.
SUPER Cabmaker GP8 Fig 14 - Carbide stick applied to diamond wheel OPERATION AND ADJUSTMENT Fig 15 - Resin belt installed and centered on expandable drum Fig 16 - Polytex pad being applied to the convex polishing disc EXPANDABLE DRUM AND DIAMOND RESIN BELTS The GP-8 Super Cabmaker comes with four diamond resin belts (8“ OD x 3" wide) in abrasive grit sizes: 400, 600, 1,200, and 3,000. These are to be placed over the edge and outer rim of the 8" x 3" rubber expandable drum (Fig 15).
SUPER Cabmaker GP8 OPERATION AND ADJUSTMENT Use only one dedicated Polytex polishing pad with each respective diamond paste syringe (i.e. keep a labeled Polytex pad for the 8,000 grit paste in a zip-lock bag labeled 8,000 grit). Do not use a single Polytex pad with two or more diamond pastes or else cross-contamination and poor polishing of the gemstone material may result.
SUPER Cabmaker GP8 OPERATION AND ADJUSTMENT Once the majority of coarse saw and grinding marks have been sanded off with the 70 grit electroplated pad, the user can replace the 70 grit pad with the 120 grit electroplated pad and repeat the process to sand flat all visible saw or grinding marks or uneven surfaces. Dry off gemstone and inspect closely.
SUPER Cabmaker GP8 OPERATION AND ADJUSTMENT DIAMOND WHEEL/CARBIDE WHEEL REPLACEMENT When worn-out, the diamond wheels and expandable drum can be removed and replaced. For all models, first prepare the arbor shaft for removal from the body of the GP-8. 1. 2. 3. 4. 5. 6. 7. 8. Unscrew and remove the locking knobs from the hood (Fig 24). Rotate the hinged hood back completely (Fig 25). Using an allen wrench, loosen set screws on the main arbor 1" to motor arbor 1/2" coupler (Fig 26).
SUPER Cabmaker GP8 maintenance SHAFT REASSEMBLY Reassembly of the shaft with the new diamond wheels is the reverse of the disassembly instructions. Please keep the following points in mind when reassembling: Fig 28 - Outside face of diamond wheel Fig 29 - Inside face of diamond Fig 30 - Bearing correctly installed 1. Install diamond wheels with the inside faces facing each other (Fig 28 & 29). Be sure the diamond wheel bushings are installed. 2.
SUPER Cabmaker GP8 Fig 35 - Bearing correctly seated maintenance Fig 36 - Bearing incorrectly seated 5. When installing the shaft assembly back in the GP-8 Super Cabmaker, make sure the rubber mounted bearings are centered in the bearing seat (Fig 35 & 36). If the bearings are not centered in the bearing seats make sure the aluminum spacers are in the correct order and that the bearings and arbor collars are properly installed. 6.
SUPER Cabmaker GP8 maintenance ARBOR ASSEMBLY The GP-8 Super Cabmaker is equipped with a 1" OD arbor shaft, two rubber sealed ball bearings and a shaft 1" to motor arbor 1/2" coupler (Fig 39). Should the bearings wear out on the arbor shaft, grinding and polishing performance and short diamond wheel/belt life may result. Additionally, premature bearing wear may result in permanent damage to the arbor shaft, and motor.
