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 The Wide-Belt Sander • DO NOT allow anyone to stand at the outfeed end when feeding your stock. • NEVER leave the machine running unattended. • DO NOT jam workpiece into the machine during operation. Firmly grasp the workpiece in both hands and ease it into the machine using light pressure. • NEVER operate the sander without an adequate dust collection system in place and operating correctly. • • DO NOT wear loose clothing while operating this machine.
SECTION 2: INTRODUCTION Read the manual before assembly and operation. Become familiar with the machine and its operation before beginning any work. Serious personal injury may result if safety or operational information is not understood or followed. We are proud to offer the Grizzly Model G9983 Wide-belt Sander. Your machine is part of a growing Grizzly family of fine woodworking machinery.
SECTION 3: CIRCUIT REQUIREMENTS 220V Single-Phase The Model G9983 features a 5 HP, 220V singlephase motor. This motor will safely draw about 30 amps under load. The Model G9983 also features a 1⁄4 HP feed motor that draws approximately 1.8 amps under load. Total amperage draw for this machine is approximately 32 amps under load. Use a 35 amp circuit breaker for the Model G9983. Make sure the wiring in your circuit is rated to handle the amperage draw from your machine.
Grounding This equipment must be grounded. Verify that any existing electrical outlet and circuit you intend to plug into is actually grounded. Under no circumstances should the grounding pin from any three-pronged plug be removed. Serious injury may occur. In the event of an electrical short, grounding reduces the risk of electric shock by providing a path of least resistance to disperse electric current.
SECTION 4: MACHINE FEATURES External Features Control Panel To help you understand the set up and operation instructions, we recommend that you become familiar with the basic features of your new sander. The control panel houses the main power switch, the feed belt ON/OFF buttons and the sanding belt ON/OFF buttons. Please refer to Figure 3 to identify these controls. Please match up the list below with the letters in Figure 2 to identify the external sander components. A.
Access Doors There are access doors located on each side of the sander. Throughout the manual, we refer to these doors as the “left-hand access door” and the “right-hand access door.” These terms are referenced as if you are facing the front of the machine. Figure 4 shows the layout behind the left-hand access door. Figure 5 shows the layout behind the right-hand access door. A. Oscillating Roller B. Oscillation Air Filter C. Limit Switch D.

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.
Handwheel Handle Beginning Assembly Most of your new wide-belt sander has been assembled at the factory, but some setup is required after delivery. We have organized the setup process into steps. Please make sure the sander is placed in its final position in your shop and follow along in the order presented in this section. To install the handwheel handle: 1. Thread the handle into the handwheel as shown in Figure 7. 2.
Platen The platen must now be set even with the sanding rollers. To set the platen even with the belt rollers: The housing for the platen can be accessed by opening the door on the left-hand side of the machine. 1. Lower the conveyor table as far as it will go. 2. Open the access door on the left-hand side and locate the platen adjustment knob shown in Figure 9. A graphite sheet is mounted on the platen.
Air Hose Sanding Belt The air hose connection is located at the regulator on the front of the machine. The Model G9983 is designed for 16" x 48" sanding belts. To connect the air hose: To install a sanding belt: 1. Fit the hose over the regulator nozzle. 1. Open the left-hand side door for access. 2. Secure the hose with a hose clamp as shown in Figure 10 and turn on your air compressor. 2.
Sanding Belt Tension The sanding belt tension is controlled by a switch located inside the upper portion of the machine (see Figure 12). To locate it, open the access door on the left-hand side of the sander. Pressure Rollers Always keep the pressure rollers set below the level of the sanding roller. If the pressure rollers are even, or higher than the sanding roller, the wood WILL be propelled from the sander at a high rate of speed. This situation could cause serious personal injury.
Dust Collection DO NOT operate the Model G9983 without an adequate dust collection system. This machine creates substantial amounts of wood dust while in operation. Failure to use a dust collection system may result in short and long-term respiratory illness. The dust collection port is located on top of the sander and measures 5" in diameter. It will be necessary to attach a 5" dust collection pipe over this port before operation.
Recommended Adjustments Long term exposure to this machine during operation may cause hearing loss. Wear approved hearing protection to minimize this risk! 2. Start both the sanding belt and the feed belt, making sure your finger is poised over the STOP button, just in case there is a problem. The wide-belt sander should run smoothly, with little or no vibration or abnormal rubbing noises. It is normal, however, for the air operated tracking to make a rhythmic back and forth noise.
SECTION 6: OPERATIONS Before Starting Keep loose clothing out of the way of machinery and keep hair pulled back during operations. Disconnect power to the machine when performing any maintenance or adjustments. Failure to do this may result in serious personal injury. Wear safety glasses during the entire operation process. Failure to comply may result in serious personal injury. Always wear a dust mask in addition to using a dust collector.
Conveyor Height Feed Belt Speed Conveyor height is controlled by turning the handwheel shown in Figure 13. A scale is located near the handwheel for gauging conveyor movement. The scale is marked in millimeters and inches. Figure 14 demonstrates how the handwheel movement affects the conveyor. The feed belt motor (shown in Figure 15 with the cover removed) controls the speed of the feed belt. The Model G9983 features speeds of 13.1 FPM and 16.4 FPM.
Load Meter Operation The load meter shown in Figure 16 displays the current amperage draw of the sanding belt motor. The needle rises when you increase the load on the sanding belts and decreases when you decrease the load. Use this meter to avoid overloading your machine with too heavy of a cut. Under most sanding conditions, a normal cut is no more than .5mm (approx. 1⁄64"). This depth can be achieved by 1⁄8th turn of the conveyor height handle.
Platen Depth Cleaning Pads The platen position allows for 3 types of operation. These different positions can be adjusted by rotating the knob shown in Figure 17. Notice that the knob has a scale on it. By keeping track of how many revolutions you have rotated the knob, you can determine how far you have moved the platen. Cleaning Pads (one is shown in Figure 18) are the perfect way to enhance your wide-belt sanding operations.
SECTION 7: MAINTENANCE Cleaning Sanding Belts Disconnect power to the machine when performing any maintenance or assembly. Failure to do this may result in serious personal injury. General Make a habit of inspecting your Model G9983 each time you use it. Failure to routinely inspect your wide-belt sander for damage and wear could result in unsatisfactory work results, premature component or machinery failure, or operator injury. We recommend you create a checklist for routine inspection and maintenance.

SECTION 8: SERVICE ADJUSTMENTS Oscillation Timing Keep loose clothing out of the way of machinery and keep hair pulled back. Disconnect power to the machine when performing any maintenance or assembly. Failure to do this may result in serious personal injury. The first step in adjusting the oscillation is timing the side to side movement the belt makes when oscillating. The belt should take the same amount of time to travel to one side as it did the other.
Oscillation Speed Use the valve shown in Figure 21 to control the speed of the sanding belt oscillation. Make sure the oscillation is balanced before adjusting the speed. Figure 20. This is the oscillation timing control knob. 5. When you get the belt to oscillate without stopping, experiment with the timing knob to see the effect its movement has on the belt oscillation. 6. Position the timing knob so the belt moves from one side to the other, back and forth, in even intervals. 7. Figure 21.
Oscillation Return Limit Switches The oscillation return keeps the sanding belt in motion. The valve shown in Figure 22 controls the oscillation return. The limit switches are mounted on both sides of the sanding belt. They are designed to stop the sander if the belt travels too far to one side of the top roller. Air Eye Fork The limit switches are factory set and should require no adjustments.
Pressure Roller Depth Left-Hand Pressure Depth Bolt Variables such as feed rate, depth of the cut, and type of sanding belt can play a big part in determining the proper amount of downward pressure exerted by the rollers. Some experimentation may be necessary with pressure roller spring tension to achieve the desired results. However, under no circumstances should the pressure roller depth be set even, or higher than, the sanding rollers or platen.
Pressure Roller Tension Pressure roller tension is largely set by trial and error. If there is not enough tension, the workpiece will not pass through the sander evenly and may possibly be launched toward the operator. If there is too much tension, the feed belt will experience premature wear and the workpiece will pass through the sander sluggishly (if at all). 4. Turning the nut on the adjustment bolt clockwise will increase the tension and counterclockwise will decrease the tension.
Feed Belt Tension Feed Belt Tracking To adjust the feed belt tension: To check the feed belt tracking: 1. Disconnect the sander from the power source! 1. Turn the feed belt ON. 2. If the belt moves to one side then you need to immediately stop the machine and adjust the belt tracking. If the belt tracks evenly, leave it alone. 2. Move the emergency brake plate up and out of the way. 3.
V-Belt Tension Replacing V-Belts The sanding belt is driven by two V-belts on the Model G9983. The V-belts must have adequate tension for proper power transmission. Proper tension is usually achieved when the V-belts can be deflected no more than 1" with moderate finger pressure at the midpoint between the widebelt pulleys and the motor pulleys. The large cover on the right-hand side of the sander must be removed to access the V-belts and the sanding motor.
Figure 29. Remove platen adjustment knob, indicator plate, and large cap screws. 6. Work the casting off the roller shafts as shown in Figure 30. Figure 31. Remove this roller shaft nut located behind right-hand access door. 8. Figure 30. Work the casting off the roller shafts. 7. Open the right-hand access door and locate the large nut shown in Figure 31 and remove it with the box wrench included with the machine.
Platen Graphite Air System The graphite sheet on the platen will wear out with use. Similar to the sanding belts, the graphite sheet is considered a “consumable” item and is not covered under the warranty. We recommend keeping replacements in your inventory to avoid downtime. To obtain replacements, use the part number in the back of this manual for ordering. The air system is durable and reliable; however, components do wear with age.
Replacing Brakes The only regular maintenance to perform on the brakes is to keep the rotor clean. This is a simple process and can be performed by spraying both sides of the rotor with automotive brake parts cleaner. The brake rotor must be free and clean of any dust, dirt, oil or moisture. Eventually the brake pads will wear out. Checking and replacing these is a simple project that can be done in the shop, with the exception of having the rotor resurfaced. Figure 33.
