Additional Safety Instructions for Bandsaws

1.DO NOT OPERATE WITH DULL OR BADLY WORN BLADES. Dull blades require more demand on the motor and are less likely to cut precisely. Inspect blades before each use.

2.NEVER POSITION FINGERS OR THUMBS IN LINE WITH THE CUT.

Serious personal injury could occur.

3.DO NOT OPERATE THIS BANDSAW WITHOUT WHEEL GUARDS, PULLEY GUARDS, AND BLADE GUARDS IN PLACE.

4.WHEN REPLACING BLADES, make sure the teeth face toward the front of the saw.

5.CUTS SHOULD ALWAYS BE FULLY SUPPORTED against the side of the conveyor table and by the pressure rollers.

6.DO NOT BACK WORKPIECE AWAY from the blade while the saw is running. If you need to back the work out, stop the bandsaw and wait for the blade to stop. DO NOT twist or put excessive stress on blade while backing work away.

7.BLADE SHOULD BE RUNNING AT FULL SPEED before beginning a cut.

8.ALWAYS FEED STOCK EVENLY AND SMOOTHLY. DO NOT change conveyor speeds during a cut.

9.THIS MACHINE IS NOT DESIGNED TO CUT METAL or other material except wood.

10.DO NOT MANUALLY STOP OR SLOW BLADE after turning the saw off. Allow it to come to a complete stop before you leave it unattended.

11.ALL INSPECTIONS, ADJUSTMENTS, AND MAINTENANCE MUST BE DONE WITH THE POWER OFF and the circuit breaker shut off. Wait for all moving parts to come to a complete stop.

12.HABITS – GOOD AND BAD – ARE HARD TO BREAK. Develop good habits in your shop and safety will become sec- ond-nature to you.

13.IF AT ANY TIME YOU ARE EXPERIENCING DIFFICULTIES PERFORMING THE INTENDED OPERATION, STOP USING THE BANDSAW! Then contact our service department or ask a qualified expert how the operation should be performed.

14.MAKE SURE BLADE IS PROPERLY TENSIONED BEFORE OPERATING MACHINE.

15.KEEP LOOSE CLOTHING AND LONG HAIR AWAY FROM MOVING CONVEYORS!

Additional Safety Instructions for Hydraulics

1.BE FAMILIAR WITH THE HAZARDS OF HYDRAULIC INJECTION INJURIES.

•Leaking hydraulic fluid may have enough pressure to penetrate skin. Never use your hands to check for suspected hydraulic leaks.

•Hydraulic fluid that is injected into skin is a medical emergency that may cause infection, disability, amputation or death.

•The average injection injury may be a small wound that has barely broken the skin. DO NOT be fooled by this type of injury. Immediately get to an emergency medical facility!

•Minimizing the time between the injury and when the injected material is removed is critical to minimizing the seriousness of the injury.

2.USE A PIECE OF CARDBOARD TO CHECK FOR SUSPECTED HYDRAULIC LEAKS. Pressurized hydraulic fluid may cause injection injuries and can be extremely hot. Never use your hands to check for suspected hydraulic leaks.

3.PROTECT YOUR EYES AROUND HYDRAULIC SYSTEMS. Safety glasses may not always protect your eyes from hot, pressurized fluid. The best way to protect yourself is to stay away from leaks until you can depressurize the system.

4.STOP THE MACHINE IF YOU NOTICE A HYDRAULIC LEAK. Allowing the machine to continue running with a leak may increase the hazard of the situation.

5.DEPRESSURIZE THE HYDRAULIC SYSTEM BEFORE ATTEMPTING TO ADJUST ANY HYDRAULIC LINES OR FITTINGS. Stop the resaw, open the conveyor speed valves, and make sure the pressure gauge reads 0 PSI.

6.DEPRESSURIZE THE HYDRAULIC SYSTEM BEFORE ATTEMPTING ANY MAINTENANCE OR SERVICE. Stop the resaw, open the conveyor speed valves, and make sure the pressure gauge reads 0 PSI.

7.REGULARLY INSPECT AND PERFORM THE PROPER MAINTENANCE ON THE HYDRAULIC SYSTEM. A wellmaintained hydraulic system will have much fewer problems and hazards than a neglected system.

8.MAKE SURE ANY HYDRAULIC SYSTEM MAINTENANCE IS PERFORMED IN A CLEAN AND DUST-FREE WORK AREA. Remove any sawdust, grime or water from hydraulic system openings or components before maintenance. Always use lint-free rags when wiping components.

9.ONLY USE HIGH PRESSURE HYDRAULIC HOSE AND STEEL HYDRAULIC FITTINGS WHEN REPLACING COMPONENTS IN THE HYDRAULIC SYSTEM. DO NOT use brass or aluminum.

Clean Up		Site Considerations

The unpainted surfaces are coated with a waxy oil to protect them from corrosion during shipment. Remove this protective coating with a solvent cleaner or citrus-based degreaser such as Grizzly’s G7895 Degreaser. To clean thoroughly, some parts may need to be removed. For optimum performance from your machine, make sure you clean all moving parts or sliding contact surfaces that are coated. Avoid chlo- rine-based solvents as they may damage painted surfaces should they come in contact. Always follow the manufacturer’s instructions when using any type of cleaning product.

Gasoline and petroleum products have low flash points and could cause an explosion or fire if used to clean machinery. DO NOT use gasoline or petroleum products to clean the machinery.

Smoking near solvents could ignite an explosion or fire and cause serious injury. DO NOT smoke while using solvents.

Many of the solvents commonly used to clean machinery can be toxic when inhaled or ingested. Lack of ventilation while using these solvents could cause serious personal health risks or fire. Take precautions from this hazard by only using cleaning solvents in a well ventilated area.

G0504 16" Horizontal Resaw Bandsaw

1.Floor Load: The Model G0504 represents a large weight load (3300 lbs.) in a large footprint. Most commercial floors are suitable for your machine. Some residential floors may require additional build up to support both the machine and operator.

2.Working Clearances: Consider existing and anticipated needs, size of material to be processed through each machine, and space for auxiliary stands, work tables or other machinery when establishing a location for your bandsaw.

3.Lighting and Outlets: Lighting should be bright enough to eliminate shadow and prevent eye strain. Electrical circuits should be dedicated or large enough to handle amperage requirements. Outlets should be located near each machine so power or extension cords are clear of high-traffic areas. Observe local electrical codes for proper installation of new lighting, outlets, or circuits.

Unsupervised children and visitors inside your shop could cause serious personal injury to themselves. Lock all entrances to the shop when you are away and DO NOT allow unsupervised children or visitors in your shop at any time!

The Model G0504 is a heavy machine that weighs approximately 3300 lbs. Serious personal injury may occur if safe moving methods are not followed. To be safe, you will need assistance and power equipment when moving the shipping crate and removing the machine from the crate.

To remove the resaw from the crate pallet:

1.Remove the lag bolts from the stand feet that secure the resaw to the crate pallet.

2.Using a wrench, remove the pressure gauge that is located on top of the hydraulic reservoir as shown in Figure 11. Note—This step is optional, but highly recommended to avoid damaging the pressure gauge. If you do this step, plug the opening on both the fitting and the gauge to keep contamination out of the hydraulic system.

Figure 11. Removing pressure gauge.

3.Using a forklift, lift the resaw from the frame location shown in Figure 12, and move it to your predetermined location.

4.After placing the resaw, make sure that you remove any plugs and replace the hydraulic pressure gauge before continuing to the next step!

Mounting Resaw to the Floor

Although not required, we recommend that you mount your new resaw machine to the floor. Because this is an optional step and floor materials may vary, floor mounting hardware is not included.

Note—The instructions below are given for a typical heavy-duty shop floor made of 6" thick concrete. Also, anchor studs may be substituted for lag bolts, but they will stick out of the floor if you decide to move your machine at a later point.

To mount the resaw machine to the floor:

1.For these steps you will need:

•Hammer drill

•1⁄2" punch

•1⁄2" hammer drill bit that is at least 6" long

•Twelve (12) 5⁄16" x 3" lag shields

•Twelve (12) 5⁄16" x 4" lag bolts

•Twelve (12) 5⁄16" extra-wide flat washers

•Hammer

2.Put on safety glasses and a dust mask before starting!

3.Use the mounting holes in the feet to act as a guide for

floor, and drill approximately 31⁄2" deep into the concrete floor.

4.Using compressed air and a vacuum hose, remove the concrete dust from the newly drilled holes.

5.Using the hammer and punch, pound the lag shields into the concrete below the stand feet and flush with the surface of the concrete.

6.Secure the resaw to the floor with the 5⁄16" lag bolts and washers.

4.Carefully fit the blade over each wheel, and position it between the blade guides as shown in Figure 14. Make sure the teeth point toward the right-hand side of the machine, as you are facing the front.

Figure 14. Blade positioned between blade guides.

5.Position the blade on the wheels so that the tooth gullet is approximately 1⁄16" over the edge of the wheel, as shown in Figure 15. Also, see the blade illustration in Figure 16 for more details about this concept.

6.Tighten the blade with the blade tensioner as shown in Figure 17. Use the colored area on the tension gauge as a proper tension guide for your specific blade material.

Carbon Steel	......................................Yellow
Bi-metal ............................................	Orange

Note—Always adjust the pressure to the lowest rating of each colored area and then increase tension as needed (blades stretch as they warm up).

Adjusting Blade

Guides

Each blade guide assembly consists of Guide Blocks and a Support Bearing.

The blade guides keep the blade stable during operation, so make sure they are properly adjusted before starting the bandsaw.

Guide Blocks

Each guide block consists of an upper and lower ceramic block that stabilizes the blade from up/down movement during operation.

The lower block is designed to remain in a fixed position, and the upper block is designed to be adjusted during each blade change. When the machine is new, the lower block is set at the factory and should not need to be adjusted (see

Section 8: Service Adjustments for more information about the lower guide). The upper block, however, should be adjusted every time you install a new blade or re-install an old blade.

To adjust the upper guide block:

1.Loosen the guide block adjustment bolt shown in Figure 18.

Support Bearing

The support bearing is positioned behind the blade to brace it from pushing backwards during a cut. Figure 20 shows the support bearing components to clarify the adjustment instructions.

gauge or four thicknesses of a dollar bill to check this.

3.Tighten the lock bolt, and repeat with the other support bearing.

4.Test the adjustment of the support bearings by spinning the wheels by hand, at full blade tension, in the same direction of operation. While you are spinning the wheels, the support bearings should not turn. (The support bearings should only turn during cutting operations.)
