SECTION 1: SAFETY For Your Own Safety Read Instruction Manual Before Operating This Equipment The purpose of safety symbols is to attract your attention to possible hazardous conditions. This manual uses a series of symbols and signal words which are intended to convey the level of importance of the safety messages. The progression of symbols is described below. Remember that safety messages by themselves do not eliminate danger and are not a substitute for proper accident prevention measures.
Safety Instructions For Power Tools 9. USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition. Conductor size should be in accordance with the chart below. The amperage rating should be listed on the motor or tool nameplate. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Your extension cord must also contain a ground wire and plug pin. Always repair or replace extension cords if they become damaged.
Additional Safety Instructions For Bandsaws 1. DO NOT OPERATE WITH DULL OR BADLY WORN BLADES. Dull blades require more effort to use and are difficult to control. Inspect blades before each use. 8. ALWAYS FEED STOCK EVENLY AND SMOOTHLY. Do not force or twist blade while cutting, especially when sawing small radii. 2. NEVER POSITION FINGERS OR THUMBS IN LINE WITH THE CUT. Serious personal injury could occur. 9. THIS MACHINE IS NOT DESIGNED TO CUT METAL or other material except wood. 3.
SECTION 2: CIRCUIT REQUIREMENTS Model G3619 Model G9963 The Model G3619 Bandsaw is pre-wired for single-phase, 220V operation. Under normal use, the Model G3619 5 HP motor draws approximately 22 amps. We recommend a 30 amp circuit. This includes a 30 amp circuit breaker and wiring rated for at least 30 amps. This should be satisfactory for normal use, while providing enough protection against damage caused by an overloaded circuit.
Model G3620/G9966 440V Operation The Model G3620/G9966 Bandsaw is pre-wired for 3-phase, 220V operation. Under normal use, the 71⁄2 HP motor for this model draws approximately 19 amps. We recommend using a 25 amp circuit, including a 25 amp circuit breaker and wiring rated for at least 25 amps. If frequent circuit breaker failures occur when using the bandsaw, contact our service department. The Model G3620/G9966 Bandsaw is furnished with a 71⁄2 HP 3-phase motor that can be wired to 440V.
Grounding Extension Cords In the event 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. A plug with a grounding pin must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances. We do not recommend the use of extension cords on 220V or 440V equipment.

Grizzly Industrial, Inc 1203 Lycoming Mall Circle Muncy, PA 17756 Phone:(570) 546-9663 Fax:(800) 438-5901 E-Mail: techsupport@grizzly.com Web Site: http://www.grizzly.com Grizzly Industrial, Inc. is proud to offer the 24" and 27" Resaw Bandsaws. These bandsaws are a part of Grizzly’s growing family of fine woodworking machinery.
Unpacking Piece Inventory The 24" and 27" Resaw Bandsaws are shipped from the manufacturer in a carefully packed crate. If you discover the machine is damaged after you have signed for delivery, please call Customer Service immediately for advice. After all the parts have been removed from the carton, you should have: Save the containers and all packing materials for possible inspection by the carrier or its agent. Otherwise filing a freight claim can be difficult.
Clean Up 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 chlorine-based solvents as they may damage painted surfaces should they come in contact.
SECTION 4: ASSEMBLY Table Keep loose clothing rolled up and out of the way of machinery and keep hair pulled back. Keep power disconnected from machine when performing the assembly process. Failure to do this may result in serious personal injury. Wear safety glasses during the entire assembly process. Failure to comply may result in serious personal injury. Beginning The photos used in this manual are of the Model G9966.
Fence Dust Port To mount the fence: To install the dust port: 1. Loosen the lock knob and slide the fence onto the rail. 1. 2. Slide the fence beyond the center of the table so the blade can be installed without blocking the fence as shown in Figure 5. Place the dust port on the saw and install it with the included Phillips head screws as shown in Figure 6. Figure 6. Dust port installed. Figure 5. Fence mounted on rail. 3.
SECTION 5: ADJUSTMENTS Identification Keep loose clothing rolled up and out of the way of machinery and keep hair pulled back. Disconnect power to the machine when performing any adjustments. Failure to do this may result in serious personal injury. Wear safety glasses during the entire adjustment process. Failure to comply may result in serious personal injury. Read through this entire manual to become familiar with the controls and the operations of the bandsaw before turning it on.
Blade Guides Always adjust the blade guides away from the blade before installing a new blade or making blade tracking/tension adjustments. 8 6 11 9 7 10 G9963/G9966 Blade Guides To move the assemblies out of the way, loosen the middle cap screws (shown in Figure 9) from the front of the blade guide assembly. These screws loosen the guide blocks which can then slide out of the way of the blade.
G3619/G3620 Tracking G9963/G9966 Tracking The wheels on the Model G3619/G3620 Resaw Bandsaws are crowned with rubber tires. This style requires center tracking for proper operation. To center track your blade: The wheels on the Model G9963/G9966 Resaw Bandsaws are considered “Flat Wheels.” This means that tracking procedures vary from the common crowned wheel bandsaws, because they do not have to be centered for proper operation. 1. Make sure the bandsaw is unplugged! To track the blade: 2.
3. Turn the upper wheel clockwise by hand and watch the blade ride on the wheels. If the bottom of the blade gullets are not approximately 1⁄16 " away from the edge of the wheels then you need to adjust the tracking handwheel on the backside of the saw. 4. Turn the tracking handwheel a few times and note the direction that the blade shifts when you spin it by hand. 5.
Guide Blocks The guide blocks ensure that the blade cannot move side-to-side too far during operation. Perform steps 1-4 for both upper and lower guide blocks. 1. Loosen the guide blocks from the center setscrew in the guide bracket. 2. The guide blocks should be approximately .004" away from the blade. This number is approximately the same as the single thickness of a dollar bill. 3.
Blade Guard Table Stop The blade guard is attached to the guide post above the upper blade guide assembly. For proper setup, the blade should be centered in the blade guard. The positive stop under the table (see Figure 15) allows you to repeatedly square up the table after adjusting the table tilt. To adjust the positive stop so the table will return perpendicular (90°) to the blade after angle cutting: To center the blade guard: 1. 1.
2. Loosen the large hex bolt and the jamnut in the center of the table trunnion. 3. Raise the upper blade guide assembly and place a 6" machinist’s square on the table against the blade as shown in Figure 16. Notice how far out of square your table is and approximate this distance by adjusting the positive stop up or down. Turning the positive stop counterclockwise will raise it and clockwise will lower it. Adjust the positive stop so the table will stop at a 90° angle (square) to the blade. 4.
Blade Tension The rest of the adjustments in this section require you to start the bandsaw. Before starting the bandsaw, make sure you have performed the preceding assembly and adjustment instructions, and you have read through the rest of the manual and are familiar with the various functions and safety issues associated with this machine. Failure to follow this warning may result in serious personal injury or even death! Test Run Turn on the power supply at the main panel.
Fence Adjustment Blade Lead The fence slides along the rail for adjustment and secures in place by tightening the star knob. Sometimes the bandsaw blade will not cut straight even when the fence and blade are parallel (see Figure 17). This condition is called “lead.” Lead occurs (1) if the blade tension is incorrect, (2) if the teeth are dull on one side, or (3) if the teeth are set heavier on one side of the blade than the other.
SECTION 6: OPERATIONS Blade Selections Keep loose clothing rolled up and out of the way of machinery and keep hair pulled back. Selecting the right blade requires a combination of the various blade characteristics mentioned below, the type of material you plan to cut, and the type of cut you are going to perform. Blade Length Disconnect power to the machine when performing any maintenance or assembly. Failure to do this may result in serious personal injury.
Figure 18 shows the three main categories of tooth style. per inch (fine pitch) will cut slower, but smoother; while fewer teeth per inch (coarse pitch) will cut rougher, but faster. As a general rule, choose blades that will have at least three, but not more than twelve teeth in the material at all times. Use fine pitched blades on harder woods and coarse pitched blades on softer woods. Blade Care Raker Skip Hook Figure 18. Raker, Skip and Hook blades.
Blade Changes Always disconnect power to the machine when changing blades. Failure to do this may result in serious personal injury. Wear gloves and safety goggles when handling blades. Coiled blades spring open as they are uncoiled and could cause deep cuts or lacerations. To replace the blade: 1. Slide the blade through the table slot, ensuring that the teeth are pointing down toward the table. To remove the blade: 1.
Ripping Stacked Cuts Ripping is the process of cutting a wide board into two or more thinner boards. See Figure 19. The maximum board width that can be ripped is limited by the maximum throat dimension of the bandsaw. One of the benefits of a bandsaw is its ability to cut multiple copies of a particular shape by stacking a number of workpieces together. For ripping, a wider blade is better. In most ripping applications, a standard raker tooth style will be sufficient.
Resawing Resawing is the process of cutting the thickness of a board into two or more thinner boards. Each new board is the same width and length as the original board, but the thickness is less. The maximum board width that can be resawn is limited by the maximum cutting height of the bandsaw. The most important consideration when resawing is blade selection. When selecting a blade, keep in mind that generally a wider blade is easier to control.
SECTION 7: MAINTENANCE Table Always disconnect power to the machine when performing maintenance. Failure to do this may result in serious personal injury. V-Belts To ensure optimum power transmission from the motor to the blade, the V-belt must be in good condition and operate under proper tension. The belts should be checked for cracks, fraying and wear. Belt tension should be checked at least every 3 months; more often if the bandsaw is used daily. The V-belt is accessed via the bottom cover.
