Safety SECTION 1: SAFETY For Your Own Safety, Read Instruction Manual Before Operating This Machine The purpose of safety symbols is to attract your attention to possible hazardous conditions. This manual uses a series of symbols and signal words 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.
WEARING PROPER APPAREL. Do not wear clothing, apparel or jewelry that can become entangled in moving parts. Always tie back or cover long hair. Wear non-slip footwear to reduce risk of slipping and losing control or accidentally contacting cutting tool or moving parts. HAZARDOUS DUST. Dust created by machinery operations may cause cancer, birth defects, or long-term respiratory damage. Be aware of dust hazards associated with each workpiece material.
Additional Safety for Jointers Serious cuts, amputation, entanglement, or death can occur from contact with rotating cutterhead or other moving components! Flying chips from cutting operations can cause eye injuries or blindness. Workpieces or inserts/knives thrown by cutterhead (kickback) can strike nearby operator or bystanders with deadly force. To reduce the risk of serious personal injury from these hazards, operator and bystanders MUST completely heed the hazards and warnings below. KICKBACK.
SECTION 2: POWER SUPPLY Power Supply Availability Circuit Information Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrician or qualified service personnel in accordance with all applicable codes and standards.
Grounding Requirements This machine MUST be grounded. In the event of certain malfunctions or breakdowns, grounding reduces the risk of electric shock by providing a path of least resistance for electric current. This machine is equipped with a power cord that has an equipment-grounding wire and a grounding plug. Only insert plug into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances.
SECTION 3: SETUP Needed for Setup This machine presents serious injury hazards to untrained users. Read through this entire manual to become familiar with the controls and operations before starting the machine! Wear safety glasses during the entire setup process! HEAVY LIFT! Straining or crushing injury may occur from improperly lifting machine or some of its parts. To reduce this risk, get help from other people and use a forklift (or other lifting equipment) rated for weight of this machine.
Inventory A The following is a list of items shipped with your machine. Before beginning setup, lay these items out and inventory them. If any non-proprietary parts are missing (e.g. a nut or a washer), we will gladly replace them; or for the sake of expediency, replacements can be obtained at your local hardware store. NOTICE Figure 6. Inventory—jointer assembly. If you cannot find an item on this list, carefully check around/inside the machine and packaging materials.

Cleanup The unpainted surfaces of your machine are coated with a heavy-duty rust preventative that prevents corrosion during shipment and storage. This rust preventative works extremely well, but it will take a little time to clean. Be patient and do a thorough job cleaning your machine. The time you spend doing this now will give you a better appreciation for the proper care of your machine's unpainted surfaces.
Site Considerations Weight Load Physical Environment Refer to the Machine Data Sheet for the weight of your machine. Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine.
Assembly The machine must be fully assembled before it can be operated. Before beginning the assembly process, refer to Needed for Setup and gather all listed items. To ensure the assembly process goes smoothly, first clean any parts that are covered or coated in heavy-duty rust preventative (if applicable). HEAVY LIFT! Straining or crushing injury may occur from improperly lifting machine or some of its parts.

Switch Pedestal Switch Cord Mobile Base Lock Knobs Motor Cord Figure 11. Location of mobile base locks. 5. Adjust feet (see Figure 12) as necessary until jointer is stable without any rocking or wobbling. Adjustable Feet Fence Tilt Handle Figure 13. Switch pedestal attached to stand, cords connected, and fence tilt handle installed.
Knife-Setting Jig (G0857) Assemble the knife-setting jig (see Figure 14) using the knife-setting jig rod, feet, and external retaining rings. Figure 14. Knife-setting jig assembly (G0857 only). Dust Collection This machine creates a lot of wood chips/ dust during operation. Breathing airborne dust on a regular basis can result in permanent respiratory illness. Reduce your risk by wearing a respirator and capturing the dust with a dust-collection system.
Test Run Tightening Belt Once assembly is complete, test run the machine to ensure it is properly connected to power and safety components are functioning correctly. The final step in the setup process must be done after approximately 16 hours of operation. During this first 16 hours, the belt will stretch and seat into the pulley groove. After this time, you must re-tension the belt to avoid slippage and burn out. Refer to Page 52 when you are ready to perform this important adjustment.
Disabling & Locking Switch The switch can be disabled and locked by inserting a padlock through the ON/START button, as shown. Locking the switch in this manner can prevent unauthorized operation of the machine, which is especially important if the machine is not stored inside an access-restricted building. IMPORTANT: Locking the switch with a padlock only restricts its function. It is not a substitute for disconnecting power from the machine when adjusting or servicing.
SECTION 4: OPERATIONS Operation Overview The purpose of this overview is to provide the novice machine operator with a basic understanding of how the machine is used during operation, so the machine controls/components discussed later in this manual are easier to understand. Due to the generic nature of this overview, it is not intended to be an instructional guide.
Stock Inspection & Requirements Stock Inspection Requirements Follow these rules when choosing and jointing stock: • DO NOT joint or surface plane stock that contains large or loose knots. Injury to the operator or damage to the workpiece can occur if a knot becomes dislodged during the cutting operation. • DO NOT joint or surface plane against the grain direction. Cutting against the grain increases the likelihood of kickback, as well as tear-out on the workpiece.
Squaring Stock 2. Surface Plane on a Thickness Planer— Opposite face of workpiece is surface planed flat with a thickness planer. Squaring stock means making it flat and parallel along both length and width, and making the length and width perpendicular to one another. The purpose of squaring stock is to prepare it for accurate cuts and construction later on.
Surface Planing The purpose of surface planing (see example Figures below) on the jointer is to make one flat face on a piece of stock to prepare it for thickness planing on a planer. Failure to use push blocks when surface planing could result in your hands contacting rotating cutterhead, which will cause serious personal injury. ALWAYS use push blocks when surface planing on jointer! To surface plane on jointer: 1.
Edge Jointing Edge jointing (see example Figures below) produces a flat and true surface along the side of a workpiece by removing uneven areas. It is an essential step for squaring up warped or rough stock and when preparing a workpiece for joinery or finishing. To edge joint on jointer: 1. Inspect stock to ensure it is safe and suitable for the operation (see Stock Inspection & Requirements section). 2. Set infeed table height to desired cutting depth for each pass.
Bevel Cutting Bevel cuts (see example Figures below) can be made by setting the fence at the desired angle and feeding the workpiece firmly along the fence face, with the bottom inside corner firmly against the table. The cutting process typically requires multiple passes or cuts to bevel the entire edge of a workpiece. To bevel cut on jointer: 1. Inspect stock to ensure it is safe and suitable for the operation (see Stock Inspection & Requirements section). 2.
Rabbet Cutting A rabbet cut removes a portion of a workpiece edge, so it fits together with an opposing, equally sized rabbet cut on another workpiece (see example Figure below). This is a classic method of joining two workpieces that is simple, yet strong. To rabbet cut on jointer: 1. Inspect stock to ensure it is safe and suitable for the operation (see Stock Inspection & Requirements section). 2. Set infeed table height to desired cutting depth for each pass.
4. Set fence to 90° and near front of jointer, so amount of exposed cutterhead in front of fence matches size of desired rabbet. Setting Depth of Cut Setting Depth of Cut 5. Start jointer. 6. Place workpiece firmly against fence and infeed table. 7. The depth of cut on a jointer affects the amount of material removed from the bottom of the workpiece as it passes over the cutterhead. CAUTION: To ensure workpiece remains stable during cut, concave sides of workpiece must face toward table and fence.
Depth-of-Cut Scale Depth of Cut Scale The depth of cut can be referenced directly from the depth scale located on the front of the jointer (see Figure 24). Note: The depth scale can be calibrated or "zeroed" if it is not accurate. (Refer to Calibrating Depth-of-Cut Scale on Page 51.) Scale Pointer The positive stop bolts control the top and bottom range of table movement. Jam nuts lock the positive stop bolts in position so they will not move during operation.
Accessories SECTION 5: ACCESSORIES Installing unapproved accessories may cause machine to malfunction, resulting in serious personal injury or machine damage. To reduce this risk, only install accessories recommended for this machine by Grizzly.

Also compatible with safety glasses! H3631 H3635 Figure 29. H4982 Jointer Knives for Model G0855.
SECTION 6: MAINTENANCE To reduce risk of shock or accidental startup, always disconnect machine from power before adjustments, maintenance, or service. Schedule For optimum performance from this machine, this maintenance schedule must be strictly followed. Ongoing To maintain a low risk of injury and proper machine operation, if you ever observe any of the items below, shut down the machine immediately and fix the problem before continuing operations: • • • • • • Loose mounting bolts.
Lubrication Lubrication Since all bearings are sealed and permanently lubricated, simply leave them alone until they need to be replaced. DO NOT lubricate them. T27914—Moly-D Machine & Way Oil ISO 68 Moly-D oils are some of the best we've found for maintaining the critical components of machinery because they tend to resist run-off and maintain their lubricity under a variety of conditions—as well as reduce chatter or slip.
SECTION 7: SERVICE Review the troubleshooting procedures in this section if a problem develops with your machine. If you need replacement parts or additional help with a procedure, call our Technical Support. Note: Please gather the serial number and manufacture date of your machine before calling. Troubleshooting Motor & Electrical Symptom Possible Cause Possible Solution Machine does not start or a breaker trips immediately after startup. 1. Incorrect power supply voltage/circuit size. 2.
Machine Operation Symptom Possible Cause Possible Solution Table is hard to adjust. 1. Table lock engaged/partially engaged. 2. Table stop blocking movement. 1. Completely loosen table lock (Page 5). 2. Loosen/reset table stop (Page 33). 1. Outfeed table set too low. Excessive snipe (gouge in end of board that is uneven 2. Knives set too high (G0857). with rest of cut). 3. Operator pushing down on trailing end of workpiece as it leaves cutterhead. 1.
Setting/Replacing Knives (G0857) Setting the knives correctly is crucial to the proper operation of the jointer and it plays an important role in keeping the knives sharp. If one knife is higher than the others, it will do the majority of the work, and thus, become dull much faster. Inspecting Knives jig included with the jointer designed The knife cutterhead on this jointer comesis with both to all theand knives evenly and atknife the correct for setting height.
Knife-Setting Jig Method 5. The infeed table is lowered to fit the jig on the cutterhead, as shown, and the knife heights are set to just touch the middle pad of the jig. The knife-setting jig included with the jointer is designed to set all the knives evenly and at the correct height in the cutterhead. Closely examine how jig touches cutterhead and knife.
5. Loosen cutterhead gib bolts, starting in the middle, and alternating back and forth until all gib bolts are loose, but not falling out. The first time you set or replace a knife, remove the gib and knife from cutterhead. Clean gib and clean inside cutterhead slot to remove all pitch or sawdust. Coat knife and gib with a metal protectant. 6. Position knife jig over knife. Loosen gib bolts until knife is completely loose. 7.
Rotating/Replacing Spiral Cutterhead Inserts (G0858) Rotating Replacing Cutterhead Inserts The spiral cutterhead is equipped with 4-sided indexable carbide inserts. Each insert can be removed, rotated, and re-installed to use any one of its four cutting edges. Therefore, if one cutting edge becomes dull or damaged, simply rotate it 90˚ (as shown below) to use a sharp cutting edge. The inserts have a reference dot on one corner.
7. Remove Torx screw and insert, then carefully clean away all dust and debris from insert and insert pocket in cutterhead. IMPORTANT: This step is critical for achieving a smooth finish with cutting operations. Dirt or dust trapped under insert during installation will slightly raise insert in cutterhead, which will leave marks on workpiece after jointing. Tip: Use low-pressure compressed air or a vacuum nozzle to clean cutterhead pocket. 8. Re-install insert with a sharp cutting edge facing outward.
5. 6. Place straightedge on outfeed table so it hangs over cutterhead, then lower outfeed table until straightedge just touches cutterhead body. Place straightedge in positions shown in Figure 49. In each position, straightedge should touch cutterhead and sit flat on outfeed table. Checking Infeed Table Checking Infeed Table 1. Follow all steps for checking outfeed table parallelism to first make sure that outfeed table is parallel with cutterhead. 2.
Adjusting Table Parallelism 2. For safe and proper cutting results, the tables must be parallel to the cutterhead. Adjusting them to be parallel is a task of precision and patience, and may take up to one hour to complete. Luckily, this is considered a permanent adjustment and should not need to be repeated for the life of the machine.
5. Tighten set screws in eccentric bushings on outfeed table. 6. Remove 1⁄8" stop release knob and infeed table covers and loosen set screws from each eccentric bushings under infeed table. 7. Place straightedge halfway across infeed and outfeed tables, and adjust infeed table even with outfeed table, as shown in Figure 55.
6. Use motor pulley to rotate cutterhead until one knife or insert is at TDC (its highest point during rotation), as shown in Figures 58–59. 7. Use outfeed table lever to set outfeed table so knife or insert barely touches straightedge, as shown in Figure 59. Top Dead Center G0857 Calibrating 1⁄ 8" Infeed Table Stop Checking Adjusting 1/8 Infeed Table Stop The infeed table on the Model G0857/G0858 has a built-in table stop that automatically sets depth of cut at 1⁄ 8".
3. Loosen jam nut on the 1⁄ 8" stop bolt (see Figure 61), and then rotate stop bolt clockwise a couple turns to move it down, so it will clear the stop plate during adjustment process in later steps. Stop Plate Setting Fence Stops Setting Fence Stops The fence stops simplify the task of adjusting the fence to 45˚ inward, 90˚, and 45˚ outward (135˚). Item(s) Needed: Qty Open-End Wrench 14mm................................... 1 Sliding Bevel.......................................................
4. Loosen jam nut on 45° stop bolt and adjust stop bolt until fence is exactly 45° inward while resting on stop bolt (see Figure 62). Verify angle, then retighten jam nut. Setting 45° Outward (135°) Stop 1. DISCONNECT MACHINE FROM POWER! 2. Loosen fence tilt lock, rotate stop block up, then tilt fence approximately 45° inward onto stop bolt (see Figure 66). Setting 90° Stop 1. DISCONNECT MACHINE FROM POWER! 2.
Calibrating Depth-of-Cut Scale 5. Loosen button head screws, adjust scale pointer to "0," then re-tighten screws (see Figure 69). Calibrating Depth Scale For best cutting results, calibrate or "zero" the depth-of-cut scale so cutting depth shown on the scale matches the actual cutting depth (per pass). Item(s) Needed: Qty Precision Straightedge 4'.................................... 1 Hex Wrench 3mm...............................................
Tensioning/ Replacing Belt Belts and pulleys will be hot after operation. Allow them to cool before handling. Tensioning Replacing Belt To ensure optimum power transmission from the motor to the cutterhead, the belt must be in good condition (free from cracks, fraying and wear) and properly tensioned. 5. Cutterhead Pulley After approximately 16 hours of operation, belts will stretch and seat into pulley grooves.
Checking/Aligning Pulleys Cutterhead Pulley Checking Aligning Pulleys Alignment Pulley alignment is an important factor in power transmission and belt life. The pulleys should be parallel to each other and in the same plane (coplaner) for optimum performance. Motor Pulley Each pulley can be adjusted by loosening the set screw that secures the pulley to the shaft, sliding the pulley in/out, and retightening the set screw to lock the pulley in place. Figure 73. Proper pulley alignment.
Checking/Adjusting Cutterhead Guard Adjusting Cutterhead Guard To check/adjust cutterhead guard for proper operation: 1. DISCONNECT MACHINE FROM POWER! 2. Set fence to 90° and move it all the way back, then pull cutterhead guard (see Figure 74) and let it go. The cutterhead guard is a critical safety feature of this jointer. You MUST install and verify its operation before using the jointer! Failure to properly install this guard will greatly increase the risk of serious personal injury.
