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. In order to prevent injury, the following safety precautions should be followed at all times!

READ OWNER'S MANUAL BEFORE USE

Before using this equipment, ensure that the person operating this machine has read and understands all of the instructions in the manual. Precaution is the best insurance against accidents.

Read and understand all safety precautions, messages, warnings and hazard symbols. You are responsible for your own safety.

ALWAYS USE SAFETY GLASSES

Safety glasses should always be worn when working around power tools. In addition, a face, dust mask or respirator should be worn if a cutting operation is dusty. Everyday eyeglasses only have impact resistant lenses and may not prevent eye injury - they are NOT safety glasses.

USE PROPER APPAREL

Do not wear loose clothing, gloves, neckties, rings, bracelets or other jewelry that may be caught in moving parts. Non-slip footwear is recommended. Wear protective hair covering to contain long hair.

Hand protection (plastic gloves) and a shop bib are recommended during sawing to prevent stains to clothing. Avoid prolonged exposure of skin to the sawing lubricant and wash skin immediately after contact. Do not touch the work material until the motor is off and the machine has come to a complete stop.

ALWAYS USE HEARING PROTECTION

To reduce the possibility of hearing loss, always use hearing protection when operating power equipment.

KEEP GUARDS IN PLACE

In order to prevent injury, never operate the saw without the guards in place!

REMOVE ADJUSTING KEYS AND WRENCHES

Form a habit of checking to see that keys and adjusting wrenches are removed from the power tool before it is turned on.

ELECTRICAL SHOCK

Never touch electrical wires or motor components while the motor is running. Exposed, frayed or worn electrical wiring and plugs can be sources of electrical shock that could cause severe injury or burns.

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.

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. Always work in a well ventilated area.

KEEP CHILDREN AWAY

All visitors and children should be kept a safe distance from the work area. Keep power cords disconnected when tool is not in use.

MAKE THE WORKSHOP KID-PROOF

Make the workshops kid-proof by using padlocks, master switches and by disconnecting all power cords.

USE THE RIGHT TOOL

Do not force a tool or an attachment to do a job that it was not designed to do.

SECURE WORK

Clamps or a vise should be used to hold work whenever practical. Keeping your hands free to operate a power tool is safer.

DO NOT FORCE THE TOOL

A power tool will do a better job and operate more safely at the feed rate for which it was designed.

USE THE RIGHT TOOL TO SERVICE THE SAW

Do not force a tool or an attachment when servicing or operating the Slab Saw. Use the correct tools for service or adjustments.

DO NOT OVERREACH

Keep proper footing and balance at all times by not overreaching.

HP30 SAFETY

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.

ONLY OPERATE AT THE PROPER SPEED

Severe personal injury and damage to the motor or equipment can result if operated at speeds above maximum.

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 to its source, when leaving the work area or when work is finished. Do not leave extension cords attached to the power cord or power receptacle (wall outlet) when leaving the work area.

CHECK FOR DAMAGED OR WORN PARTS

Before using a power tool, check for damaged parts. A guard or any other part that is damaged should be carefully checked to determine if it would operate properly and perform its intended function. Always check moving parts for proper alignment or binding. Check for broken parts and mountings and all other conditions that may affect the operation of the power tool. A guard, or any damaged part, should be properly repaired or replaced.

USE RECOMMENDED ACCESSORIES AND PARTS

Consult the owner’s manual for recommended accessories and parts. Using improper parts and accessories may increase the risk of personal and/or bystander injury.

USE THE PROPER EXTENSION CORD

If using an extension cord, make sure it is in good condition first. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage that will result in a loss of power and overheating.

USE THE PROPER POWER SOURCE

This tool is only to be used with a 220 volt 60 Hz power source. Ensure power source is at least 15 amps and 220 to 240 volts. Low voltage current can adversely effect electric motor performance and overall life.

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 Slab Saw.

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. In addition, California and some other authorities have listed respirable crystalline silica as a substance known to cause cancer. When cutting such materials, always follow respiratory precautions.

Use appropriate NIOSH-approved respiratory protection where dust hazard may occur. Paper masks or surgical masks without a NIOSH approval number are not recommended because they do little to protect the worker. For more information about respirator programs, including what respirators have received NIOSH approval as safe and effective, please visit the NIOSH website at: http://www.cdc.gov/niosh/npptl/topics/respirators

Observe OSHA regulations for respirator use (29 C.F.R.§1910.134 and §1503.1).

Visit http://www.osha.gov for more information.

CALIFORNIA PROPOSITION 65 MESSAGE

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contain chemicals known (to the State of California) to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead, from lead-based paints

• Crystalline silica, from bricks and cement and other masonry products

• Arsenic and chromium, from chemically treated lumber

For further information, consult the following sources: http://www.osha.gov/dsg/topics/silicacrystalline/index.html http://www.cdc.gov/niosh/docs/96-112/ http://oehha.ca.gov/prop65/law/P65law72003.html http://www.dir.ca.gov/Title8/sub4.html

http://www.P65warnings.ca.gov

Your risk from these exposures varies depending on how often you do this type of work. To reduce your exposure to these chemicals, work in a well-ventilated area, and work with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.

Where use of a dust extraction device is possible, it should be used. To achieve a high level of dust collection, use an industrial HEPA vacuum cleaner. Observe OSHA 29 CFR part 1926.57 and 1926.103.

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. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.

• Do not modify the plug – if it will not fit the outlet; have the proper outlet installed by a qualified electrician.

• Improper connections of the equipment-grounding conductor can result in a risk of electric shock.

The equipment-grounding conductor is the wire that has a green outer surface, with or without yellow stripes. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live terminal.

• Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the tool is properly grounded.

• Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool’s plug.

• Repair or replace a damaged or worn cord immediately.

To avoid the possibility of the appliance plug or receptacle getting wet, position the saw to one side of a wallmounted receptacle. This will prevent water from dripping onto the receptacle or plug.

A "drip loop," shown in Figure 1, should be arranged by the user to properly position the power cord relative to the power source.

The "drip loop" is that part of the cord below the level of the receptacle, or the connector, if an extension cord is used. This method of positioning the cord prevents the travel of water along the power cord and coming in contact with the receptacle.

If the plug or receptacle gets wet, DO NOT unplug the cord. Disconnect the fuse or circuit breaker that supplies power to the tool. Then unplug and examine for presence of water in the receptacle.

To reduce the risk of electrocution, keep all connections dry and off the ground. Do not touch the plug with wet hands.

Figure 1

HP30 SAFETY

WARNING This tool is intended for use on a circuit that has an outlet that looks similar to the one shown in Sketch B of Figure 2. The tool has a grounding plug that looks similar to the plug illustrated in Sketch A of Figure 2. Make sure the tool is connected to an outlet having the same configuration as the plug. No adapter is available or should be used with this tool. If the tool must be reconnected for use on a different type of electric circuit, the reconnection should be made by qualified service personnel; and after reconnection, the tool should comply with all local codes and ordinances.

(A)

Figure 2

(B)

If permanently connected, this tool should be connected to a grounded metal permanent wiring system; or to a system having an equipment-grounding conductor.

NOTE: Use of a temporary adapter is not permitted in Canada.

Use of under-sized extension cords result in low voltage to the motor that can result in motor burnout and premature failure. Barranca Diamond warns that equipment returned to us showing signs of being run in a low voltage condition, through the use of undersized extension cords, will be repaired or replaced totally at the customer's expense. There will be no warranty claim.

HP30 OIL/COOLANT

RECOMMEND CUTTING OILS FOR BARRANCA SLAB SAW

Never run a diamond blade dry as this can immediately damage your blade. Use one of the oils/ coolants recommended below. Coolant should be kept clean and below 100º F. Sludge should be removed periodically and replaced with fresh coolant so that your cuts will be clean and your blades will not be damaged.

SHELL DIALA AX

Electrical transformer cooling oil. A highly refined petroleum product available at oil distributors that carry Shell products. Purchased mostly by the electrical utility companies for transformers and usually available in 5 gallon drums (one gallon jugs are not available). Has a slight odor but is excellent for slab sawing. Excellent lubricating properties for blades and saw parts. Flushes sludge from rock easily, degreases easily, and sludge settles in saw tank well.

CHEVRON TEXACO BRIGHT-CUT

A chlorine-free cutting oil with reduced sulfur and fat content. Light in color and low in odor.

HYVOLT II

Electrical transformer cooling oil. A highly refined petroleum product, available from some non-

Shell oil distributors, typically only in 55 gallon drums. Same properties and performance as Shell

Diala AX.

CHEVRON SUPERLA #5

Food grade mineral oil. Non-hazardous lubricating oil for bakeries, breweries and food processing machinery. Good lubricating properties, degreases and settles sludge well. Can go rancid over time (1 year or less).

AVATEC 80

Food grade mineral oil, excellent for slab sawing in all our slab saws.

TEXACO ALMAG

Pure petroleum based machining cutting oil. Good for slab sawing but very strong odor. Often the cheapest priced oil available but odor is tough to eliminate.

ROC CUT

Roc Cut from Diamond Pacific is a new synthetic water soluble cutting addictive with rust inhibitors. Mix 30 to 1 (water to Roc Cut).

ROC-OIL

Roc-Oil from Diamond Pacific is a oil coolant for heavy duty cutting. Provides excellent blade protection and will not cause rust to your blade or saw.

STELLAR LUBRICANT

Orange scented mineral oil for use in Lapidary Saws and equipment. This oil is non-toxic, environmentally conscious and has excellent heat dispersion properties. Flash Point 305°F.

HP30 OIL/COOLANT

SMOKEY’S EZ CUT

Synthetic water based cutting agent (mix ratio: 3 ounces per gallon)

WATER

Water is not recommended as a cutting fluid as it is a coolant only and does not promote good cutting performance. Water can shorten blade life and often frequent blade sharpening may be required. However, it can be used if a water soluble synthetic agent/additive such as Smokey’s

EZ Cut or Diamond Pacific Roc Cut is used to extend blade life and promote improved sawing.

Even with additives, frequent blade sharpening may be required. These additives have rust inhibiting properties but oxidation can still result over time as mist and heat can cover the blade arbor threaded shaft and jam nut with water during and after sawing. For this reason, if water with or without an additive is used as a cutting fluid, the user is advised to use water displacing WD-40 sprayed on the blade core and shaft/nut after every cutting session to inhibit rust formation.

Under NO circumstances should any of the following fluids be used in any Lapidary Saw:

AUTOMOTIVE ANTIFREEZE COOLANT

Ethylene glycol based automotive antifreeze and its vapors are hazardous and toxic. Propylene glycol based antifreeze is non-toxic but has practically no lubricating properties; it functions as a coolant only and its use will lead to rapid blade wear and dulling.

AUTOMATIC TRANSMISSION FLUID

Does not have adequate lubricating properties for lapidary saws; vapors are considered hazardous and toxic.

CNC MACHINING FLUIDS

Water soluble synthetic coolants (i.e. Valenite or Cimtool) are often mixed in a 20:1 blend with water. Fluid vapors are considered hazardous. These fluids do not have adequate lubricating or rust inhibiting properties for the cast iron and steel parts in lapidary slab and trim saws.

DIESEL, HEATING OIL AND KEROSENE

Very flammable with a low flash points. At least 3 of our commercial cutting customers in Arizona and Pacific

Northwest have burned down their shops using these fluids. Can be very tough to degrease the residue and aroma out of the cut slabs. These fluids are cheap, but very hazardous to use. Diesel is a benzene compound which is carcinogenic. All these fluids can cause severe skin rashes and other ailments.

HP30 STARTUP

PRE-START INSPECTION

The pre-start inspection should be performed before beginning any job.

1. Check Oil Level

Oil should always be about 1/4" from the return of the bottom of the blade. The pump should always be completely covered. Do not overfill the reservoir tank!

CAUTION 2. Check Blade

Check blade signs for core or segment cracks, uneven segment wear, pounding out of round arbor hole, undercutting, segment loss, dishing or loss of tension. If the diamond blade shows signs of any of these problems the blade must be replaced before starting work. A damaged blade will not cut correctly and could cause physical injury.

STARTUP

Saw Lubricant

The saw tank reservoir should be filled with 20 gallons of oil, or approximately 1/4" from tank return edge. This ensures adequate oil for the pump to run and keep the blade lubricated. The HP-30 saw is equipped with an oil delivery pump, which disperses the oil directly onto the blade before going through the rock.

Periodically check the oil tank level after each day of use to ensure an adequate oil level of lubrication oil is in the tank. Expect loss of cutting oil over time due to misting, absorption into the rock material and heat evaporation.

Oil Level

(1/4" from return)

Power Switch

The motor requires no special preparation or adjustment prior to use of the slab saw. The on/off power control toggle switch is located on the front of the saw. Pull the toggle switch away from the saw to start the electric motor. Push the toggle switch toward the saw to stop the electric motor.

HP30 STARTUP

Automatic Shutoff

Once a rock specimen has been securely vised inside of the saw, the operator can adjust the automatic shut-off control switch by moving the link chain to the desired position where the rock and vise are anticipated to complete the desired cut. By moving the vise forward with the rock in place, the operator can see where the chain slack needs to be adjusted to stop the unit automatically. Movement of the vice will tension the chain to a point where it will pull the ON/OFF switch to the OFF position and shut-off the power feed and blade shaft motor automatically.

Automatic shut-off chain adjustment to carriage hook

CAUTION

Never operate the saw with the hood open.

NEW BLADE BREAK-IN PROCEDURE

Be sure to wipe off any and all carbide or abrasive grit particles from the cross and main feed screw rod and rails. It is recommended, upon initial use of the Slab Saws to cut material that is abrasive yet soft such as carbide brick or cinder block to remove the factory paint and open the blade’s diamond segment for optimal cutting performance. Use of a sharpening stone such as aluminum oxide or carborundum is acceptable only if the sharpening brick is placed securely in the vise.

CAUTION

Diamond Blades improperly used are dangerous. Comply with American National Standards Institute

Safety Code, B7.1 and, Occupational Safety and Health Act covering Speed, Safety Guards, Flanges,

Mounting Procedures, General Operating Rules, Handling, Storage and General Machine Conditions.

Never hold a sharpening stone to the blade by hand. Use of the vise is mandatory under all operation conditions. Never over sharpen the blade as it will cut down the blade life. Periodically, the diamond blades should be "dressed open" or sharpened by making several passes through a green carbide brick, aluminum oxide (60-100 grit) or abrasive stone such as cinder block or red brick.

Should the saw experience difficulty in cutting, inspect the diamond blade for loss of tension, temper, wobble, pounding, dishing, or glazing of the diamond cutting edge (kerf.) Resharpening of the blade may be required periodically when cutting dense and hard material. Segmented rim and continuous rim 303

Pro blades are NOT repairable. Be sure blade flanges are at least 1/6 the blade diameter (i.e. a 24" blade requires a set of flanges at least 4" in diameter). Undersized flanges will result in blade tension loss.

HP30 OPERATIONS & ADJUSTMENTS

ADJUSTMENT AND OPERATION

Cutting Setup:

CAUTION DO NOT FORCE the blade to cut, it will do the job better and safer at a rate for which it was designed.

Rock Vise/Carriage Operation

The carriage and rock vise work together to securely hold the rock specimens during movement of the material in the carriage toward and into the notched rim diamond blade. It is very important that the rock specimen be tightened by use of the hand screw threaded bolt at the back of the rear vise plate once the specimen has been pushed forward and is in firm contact with the front plate. Both front and rear vise plates are constructed of 1/2" plywood to give firm and tight grip to the rock specimen.

Should replacement be needed due to wear or breakage, the parts can be ordered from Barranca Diamond Products. Wedges of wood can be used in the voids between the rock specimen and vise plates to enhance the surface contact and pressure hold prior to tightening the vise screw bolt. Be sure to recheck the tightening screw prior to operation.

Carriage and rock vise

HP30 OPERATIONS & ADJUSTMENTS

Handle Crank Cross Feed Adjustable Rock Cut Index Control

To use the crank cross feed index wheel, simply clamp and secure the cutting material into the vise by using the clamp screw to tighten the vise and turn the wheel crank until the desired slab thickness is achieved. You can measure the slab thickness with a ruler prior to cutting, but remember, depending on blade thickness, the amount of waste material from the rock specimen will vary. Always allow the rock cut to go to completion before opening the hood of the saw. Do not over crank the vise to the far left or right position on the carriage.

Cross feed index, crank the handle and clutch lever assembly

Automatic Feed Engagement/Disengagement System

Slab Saws are designed for operation with an adjustable clamping vise and self-feeding carriage mount. The clutch engagement/disengagement lever should be positioned in the straight upward (12 o'clock) position to disengage the clutch and allow the carriage to move freely along the rails. To engage the clutch, simply turn the lever in the downward (3 or 9 o'clock) position to securely engage the bronze shoe and block with the stainless steel thread. Should the carriage not move freely on the rails, clean the rails with a clean rag and place a liberal amount of wheel bearing grease on all surfaces of the steel rails to assist in the free movement of the carriage.

Clutch lever in disengaged position

Clutch lever in engaged position

HP30 OPERATIONS & ADJUSTMENTS

Clutch Adjustment Procedure

The clutch system on HP Slab Saw is comprised of three main components: a bronze clutch shoe

(fig. 1) that is raised and lowered by a lever activated cam (not shown), the feed screw (fig. 2) that drives the vise carriage when the clutch assembly is engaged, and the brass pressure block (fig. 3) that applies downward pressure against the feed screw to keep it engaged with the clutch block.

Fig. 1: Clutch block Fig. 2: Clutch block & feed screw

Fig. 3: Clutch assembly with pressure block

Over time, the brass pressure block can wear due to contact with the rotating feed screw. This can cause the clutch block to not properly engage the feed screw. Should the clutch block not fully engage the carriage will not travel properly and the position of the pressure block will need to be adjusted. To access the pressure block adjustments, use the cross feed handle to move the center slot in the vise assembly (fig. 4) so that the clutch block adjustment screws are visible through the slot

(fig. 5). In Figure 6, the vise has been removed from the carriage assembly to clearly show the clutch block adjustment screws.

Fig 4: Vise assembly Fig 5: Vise assembly centered over clutch block adjustment screws

Fig 6: Clutch block adjustment screws

HP30 OPERATIONS & ADJUSTMENTS

Above the pressure block in the carriage, there are two allen head set screws that are used to adjust the height of the pressure block. There is also a flat head machine screw that locks the pressure block in place (fig. 6).

To adjust the pressure block, first loosen the flat head machine screw that locks the pressure block

(fig. 7). Then use an allen wrench (fig. 8) to rotate each of the two set screws one-quarter turn (fig. 9) in a clock-wise direction.

Fig. 7: Pressure block locking screw

Fig. 8: Allen head wrench in front set screw

Fig. 9: Allen head set screw rotated 1/4 turn

Retighten flat head screw after adjusting the two set screws. Re-engage the clutch and restart saw to check if feed is working properly. If the carriage feed is still not working properly, repeat the adjustment procedure and restart saw to check feed.

Adjustment of the clutch and pressure block must result in an even, flat position against the feed screw when clutch block is engaged (fig. 10). Uneven adjustment of set screws will put pressure on one end of clutch (fig. 11), causing premature part failure and/or binding of the feed screw.

HP30 MAINTENANCE & TROUBLESHOOTING

MAINTENANCE FOLLOWING USE

The following maintenance should be performed following each use.

WARNING Place the ON/OFF switch in the OFF position and unplug cord prior to servicing and when changing accessories, such as blades, belts, and the like.

Blade-Shaft Bearings

Remove sheet metal cover over blade shaft and grease zerk fittings on base mount bearings. Use premium wheel bearing grease to lubricate all blade-shaft bearings.

Shaft bearings

Cross-Adjustment Rail System

The slab saw cutting oil splash will adequately lubricate the vice screw-feed, rails and clutch parts.

If the carriage becomes hard to slide over the rails, clean the rails with WD40 spray and a rag and apply a liberal amount of Lucas oil stabilizer or grease to the surface of the steel rails to facilitate travel of the carriage over the rails. Depending on rock type slabbed, this procedure may have to be repeated more frequently.

Use plumber's pipe wrench to remove drain cap. Allow free liquid to drain to a pan. Use a spatula to remove sludge from tank bottom toward drain hole. Use of plumbers tape on the drain pipe threads will adequately seal the cap to thread contact to prevent leaks.

MONTHLY MAINTENANCE

The following should be performed monthly. Items should be lubricated as directed.

Drain Cap

Shaft Bearings

Grease zerk fittings on sealed ball bearing every 20 to 30 hours of use. Rotate shaft periodically while greasing zerk fittings.

Drive Belts

The belt tension from the motor to blade shaft and worm drive gear are factory preset for immediate operation. However, the belt tension can be adjusted by adjusting the motor mount plate under the oil reservoir box with an open end wrench.

Periodically, the belt tension should be checked by opening the belt guard metal cover and ensure at least 1/2 to 3/4 inch of belt defection is observable. Never over tighten the drive belt as premature motor, bearing and pulley wear may occur. Even though the idler pulley contains sealed ball bearings that do not require lubricant, a small amount of spray oil lubricant or grease can be used periodically to keep the idler shaft and pulley in free spinning condition. Do not allow oil or lubricant to come in contact with the v-belts. Always ensure the spring on the idler pulley arm is attached and not damaged.

Some periodic lubrication at the idler shaft/pulley will be necessary. Use a light oil for this bearing to shaft contact surface. Retighten allen set screws on all pulleys if loose.

HP30 MAINTENANCE & TROUBLESHOOTING

Worm Shaft and Pinion Gear Lubrication

The worm drive shaft and pinion gear lubrication box on the rear of the saw should be checked for adequate grease lubrication periodically. Remove cover to check lubricant, remove the cover by removing the four mounting screws that attach the cover to the gear box. Check the level of the grease lubricant in the box by ensuring that gear box is filled at least 1/3 of the volume of the box (up to 1 to 1

1/2 inches from bottom of box), such that the bottom of the bronze gear teeth are immersed in the lubricating grease. A common automotive bearing lithium or moly type grease lubricant should be used.

The bronze pinion gear and worm shaft will need to broken-in as the unit is first used, causing some heat to build up on the gear shaft and lubricant box during this initial broken period. The grease level in the box should be checked and refilled if necessary after approximately 2 to 3 hours of initial use, be sure the worm and bronze gear teeth mesh together. A premium grade wheel bearing grease for high temperature use is recommended.

Diamond Blade Change-Out

Hold blade in one hand and use a wrench to turn shaft nut counterclockwise and remove nut and flange from shaft. After reinstalling blade, replace flange and nut and retighten. Do not over tighten shaft nut.

Lubrication Points

Use premium grade wheel bearing grease when lubricating the saw. Clean the zerk fitting when finished lubricating. Apply grease slowly; stop when grease is seen between joints. Rotate blade and driveshaft slowly by hand to spread grease uniformly into ball bearings.

V-Belt Inspection, Adjustment and Replacement

Look for frayed or split belts. Tighten belts for 1/2" to 3/4" of deflection from center of belt. Do not over tighten.

HP30 MAINTENANCE & TROUBLESHOOTING

TROUBLESHOOTING

Saw Will Not Start

Check power cord and receptacle.

Motor Overheating

If motor overheats, allow to cool for 2 to 3 hours, push reset button with power disconnected, hookup power cord and resume cutting by pulling the power switch to the ON position.

All motors have automatic thermal protection and will shut off if overheated. Do not use long (25'+) drop cords.

Motor reset button

Vise carriage cannot be moved by hand when clutch is disengaged

Adjust clutch, see clutch adjustment procedure on page 16. Check to see if carriage is disengaged from screw feed by placing clutch lever in 12 o'clock position and moving carriage by hand over rails.

Vise carriage does not move automatically when clutch is engaged

Clutch block thread may be stripped or worn. Remove and replace bronze clutch block.

Blade will not cut properly

Check for damaged or glazed diamond cutting kerf (segments). Replace damaged blades or resharpen dull segmented blades.
