TABLE OF CONTENTS Thank you for selecting the Barranca Diamond Cab Combo Workshop. We are certain that you will be pleased with your purchase. Barranca Diamond takes pride in producing top quality products for hobbyists and commercial lapidary users throughout the world. This product is manufactured in the United States. This owner’s manual contains information necessary to operate and maintain your Cab Combo Workshop safely and correctly.
CAB COMBO WORKSHOP SAFETY SAFETY PRECAUTIONS Read and follow all safety, operating and maintenance instructions. Failure to read and follow these instructions could result in injury or death to you or others. Failure to read and follow these instructions could also result in damage and/or reduced equipment life.
CAB COMBO WORKSHOP SAFETY DISCONNECT TOOLS Power tools should always be disconnected before servicing or when changing accessories, such as blades, bits, cutters and the like. REDUCE THE RISK OF UNINTENTIONAL STARTS Make sure the ON/OFF switch is in the OFF position before plugging in a power tool. ROTATING OR MOVING PARTS Keep hands, feet, hair, and clothing away from all moving parts to prevent injury. Never operate the engine with covers, shrouds or guards removed.
CAB COMBO WORKSHOP SAFETY DO NOT OVERREACH Keep proper footing and balance at all times by not overreaching. DO NOT OPERATE A TOOL WHEN TIRED When tired, take a break and relax. DIRECTION OF FEED Always feed work into a blade or cutter in the direction shown in this manual. All blades, grinding wheels or polishing belts should always be installed such that rotation is in the direction of the arrow imprinted on the blade, wheel or belt.
CAB COMBO WORKSHOP SAFETY USE THE RECOMMENDED COOLING AND LUBRICATING FLUIDS Never operate a tool dry that requires coolant or lubricant. This can lead to shortened tool life, tool damage and personal injury. MAINTAIN TOOLS WITH CARE Keep the diamond blade sharp, the sawing lubricant clean and reservoir filled to the correct level for the best and safest performance. Always follow the maintenance instructions for sharpening the blade, lubricating and servicing the Cab Combo Workshop.
CAB COMBO WORKSHOP 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.
CAB COMBO WORKSHOP 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 Fig 2, should be arranged by the user to properly position the power cord relative to the power source.

CAB COMBO WORKSHOP SETup CONTENTS In the shipping crate, you will find one Barranca Diamond Cab Combo Workshop, one 6" x 0.020 x 5/8" 303 Pro diamond blade, one Ground Fault Circuit Interrupter (GFCI) and one 1" x 1" x 6" sharpening stick. If included as part of your specific order you will also find a variety of accessories. UNPACKING Your Cab Combo Workshop has been shipped from the factory thoroughly inspected and tested.
CAB COMBO WORKSHOP SETup INSTALLATION OF BLADE Remove the saw table by unscrewing the four flat-head machine screws (fig 1) that secure the table to the reservoir tank. Remove the saw table and the cork gasket installed between the saw table and reservoir tank. Remove the diamond blade from its carton and mount on the 5/8" blade arbor between the two aluminum flanges (fig 2 & 3) with the concave sides of the flanges facing the blade (fig 4).
CAB COMBO WORKSHOP SETup INSTALLATION OF BLADE (continued) Fill the coolant reservoir so that the lubricant fluid covers the bottom 1/4" of the blade (fig 6). Do not overfill the oil reservoir, as excess fluid will result in unnecessary spraying of fluid while sawing, possibly causing damage to the arbor bearings and motor. Once the lubricant has been added, position the cork gasket on top of the reservoir (fig 7) and reattach the saw table with the four mounting screws (fig 8).
CAB COMBO WORKSHOP SETup Rock Vise A trim saw rock vise assembly (part number 8300015 - fig 9) is optional with the Cab Combination Workshop. This assembly is purchased separate from the unit as it does not come as standard equipment with the Cab Combo Workshop (diamond or carbide). The vise can be ordered as an assembly, ready to be installed on the trim saw table to enable the user to securely hold gemstone material while trimming to the desired thickness.
CAB COMBO WORKSHOP OPERATION AND ADJUSTMENT PRE-START Remove the belt guard and check to see that the belt is properly tensioned. Finger tip pressure on the belt (halfway between the motor and drive shaft pulleys) should show approximately 1/2" of belt deflection (fig 14). If the belt requires adjustment, loosen the motor mounting bolts and move the motor slightly toward the saw to decrease belt tension or away from the saw to increase belt tension.
CAB COMBO WORKSHOP OPERATION AND ADJUSTMENT START-UP Place the Cab Combo Workshop 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. Plug the enclosed Ground Fault Circuit Interrupter (GFCI) Switch into a 110 to 120 volt 60 Hz minimum 15-amp circuit wall outlet (fig 18). If needed, plug an extension cord into the GFCI.
CAB COMBO WORKSHOP OPERATION AND ADJUSTMENT PUMP SET-UP A submersible electric water pump is used to supply water to the polishing wheels as coolant and lubricant. The pump has a flow control adjustment on one side and should be adjusted for maximum water intake (fig 23). It is recommended that a 5 gallon bucket be used as a water reservoir into which the submersible pump should be placed. The level of the reservoir water should be monitored so that water pump always remains fully submerged.
CAB COMBO WORKSHOP OPERATION AND ADJUSTMENT PUMP SET-UP (continued) Keep the water hose away from the electric motor and belt guard to prevent damage from moving parts and electric shock hazard. The pump should always be used with clear, clean water so as to avoid grit/abrasive material or rock fragments from scratching the gemstones during polishing. For optimal water flow, adjust both the pump and the brass intake valve to their fully open positions.
CAB COMBO WORKSHOP OPERATION AND ADJUSTMENT TRIM SAWING Trim saw cutting of rock material is best performed on material that is under 1/2" in thickness and less than 4" in length. The rock slab to be cut should rest firmly and flatly on the saw table in front of the blade prior to beginning a cut (fig 29). Cut the slab using light but firm pressure, letting the blade do the work without forcing the slab.
CAB COMBO WORKSHOP OPERATION AND ADJUSTMENT mount can be adjusted by loosening the positioning bolt (fig 33), moving the tool rest to the desired height and distance from the wheel, and then retightening the positioning bolt. The tool rest can also be completely removed (fig 34) from the Cab Combo Workshop if the operator desires.
CAB COMBO WORKSHOP Fig 35 - Carbide stick applied to diamond wheel OPERATION AND ADJUSTMENT Fig 36 - Resin belt installed and centered on expandable drum Fig 37 - Polytex pad being applied to the convex polishing disc EXPANDABLE DRUM AND DIAMOND RESIN BELTS The Cab Combo Workshop comes with four diamond resin belts (6“ OD x 1-1/2" wide) in abrasive grit sizes: 400, 600, 1,200, and 3,000 (6 micron).
CAB COMBO WORKSHOP OPERATION AND ADJUSTMENT POLISHING WITH DIAMOND PASTE (continued) Lightly smear with your fingertip a small amount diamond paste on the center of the mounted Polytex pad with the unit operating and the polishing disc rotating. The diamond paste will evenly spread over the surface of the Polytex pad once polishing of the gemstone starts. Move the gemstone in a rocking and rotating motion from the center of the disc toward the outside edge.
CAB COMBO WORKSHOP MAINTENANCE DIAMOND WHEEL REPLACEMENT When worn-out, the diamond wheels and expandable drum can be removed and replaced. 1. Remove the belt guard from motor mount (fig 40). 2. Loosen the motor mount nuts, sliding the motor toward the saw so that the belt can be removed from the motor pulley (fig 41). 3. Remove the 4 flat-head screws that secure the saw table (fig 42) and remove the saw table from the coolant tank (fig 43). 4. Remove the blade from the arbor shaft. 5.

CAB COMBO WORKSHOP MAINTENANCE COOLANT REPLACEMENT The trim saw tank on the Cab Combo Workshop requires periodic routine maintenance to remove and properly discard the build-up of rock mud, sludge and dirty lubricating fluid (oil) from the oil tank reservoir. It will be apparent to the user after prolonged sawing that the lubricating fluid is dirty and needs to be changed if the oil residue on the saw table (after cutting) is thick and dark with rock sludge build-up.
CAB COMBO WORKSHOP MAINTENANCE deflection when the belt is pushed down (fig 63). If the belt tension should become loose, poor sawing performance or slipping will result. If the belt is too tight (i.e. no deflection) the belt, electric motor, pulleys and blade arbor bearings may wear out prematurely or the motor may overheat and shut off.
CAB COMBO WORKSHOP MAINTENANCE ELECTRIC MOTOR The Cab Combo Workshop is equipped with a 1/3 HP 1725 RPM single-phase 120 volt 60 Hz 8 amp motor. The motor shaft has sealed ball bearings and requires no lubrication. The motor is protected from thermal damage (overheating) with an automatic shut-off switch. If the motor overheats it will automatically shut off and restart once its internal components cool down and the motor is restarted manually (red button).
CAB COMBO WORKSHOP MAINTENANCE SUBMERSIBLE PUMP Periodically remove the plastic inlet cover on the submersible water pump (fig 67 & 68). Remove the filter element (fig 69) and clean any obstructions such as sludge or rock mud that may be found. Clean the filter with warm, soapy water. Replace the filter (fig 70 & 71) and test the pump to ensure it's functioning properly.
