Failure to do this may result in seri- ous personal injury. Regular periodic maintenance on your Model H2801 4" Jointer ensures its optimum performance. Make a habit of inspecting your jointer each time you use it. Check for the following conditions and repair or replace when necessary. 1. Loose mounting bolts. 2. Worn switch. 3. Worn or damaged cords and plugs. 4. Damaged V-belt. 5. Any other condition that could hamper the safe operation of this machine. Table The table and other non-painted surfaces on the Model H2801 should be protected against rust and pitting. Wiping the table clean after every use ensures that wood dust isn’t allowed to trap moisture against bare metal surfaces. Tables can be kept rust-free with regular applications of products like Boeshield® T-9. For long term storage you may want to consider products like Kleen Bore's Rust Guardit™. Lubrication Since all bearings are sealed and permanently lubricated, simply leave them alone until they need to be replaced. Do not lubricate them. Table ways and the fence assembly should not be lubricated. If the tables appear to be stuck, disassemble and clean any foreign materials from the ways. V-Belt Avoid getting grease or oil on the V-belts or pulleys. Check the V-belts, as part of a monthly inspection for proper tension and belt condition. Cracking and glazing could result in belt failure. Replace the belt if such conditions appear. Sharpening Knives The cutterhead knives can be individually honed with a fine sharpening stone. Make sure the oilstone is flat and you have the experience and equipment to properly sharpen knives. Even the slightest nick or uneven honing can result in poor quality cutting during operation. Consider taking your knives to a professional sharpener. This will guarantee that you get good results. Often the costs of getting your knives sharpened by a professional will offset any costs related to sharpening problems (i.e. ruined stock). -20- H2801 4" Jointer Replacing Knives To replace the cutterhead knives: 1. Unplug the power from the jointer! 2. Block the cutterhead guard so it stays open, or remove the cutterhead guard. Lift the knife and knife clamp from the cutterhead and clean any sawdust and resin buildup from the cutterhead and knife clamp. 3. Position the knife clamp against the replacement knife and install the assembly in the cutterhead. 4. Secure the knife and knife clamp with the three knife clamp screws. Do not completely tighten the knife clamp screws yet. 5. Check and adjust the knife height as described in the “Knife Adjustment” instructions. Tighten the knife clamp screws. 6. Recheck the knife height and make sure knife is still level with the outfeed table. 7. Repeat these procedures with the other knife, then make sure that all of the knife clamp screws are tight. Replace the guard! Replacing Belt To replace the belt: 1. Unplug the power from the jointer! 2. Lay the Model H2801 on its back so the switch is facing up, and remove the belt by turning the pulley while applying outward pressure. 3. Install the new belt by turning the pulley while applying inward pressure. Replacing Spring If the guard spring loses its tension, it must be replaced. To replace the guard spring: 1. Unplug the power from the jointer! 2. Follow the “Guard Adjustment” instructions for removing the knife guard. 3. Remove the spring from the dimple and get a new spring from the Grizzly service department. 4. Follow the “Guard Adjustment” instructions for replacing the spring and guard cover. Motor Brushes After prolonged use, the motor brushes may eventually wear out. Call the Grizzly parts department to obtain replacement brushes. To inspect/replace these brushes: 1. Unplug the power from the jointer! 2. Under the outfeed table, there are four bolts that attach the motor to the jointer base. Remove these bolts and remove motor from the jointer. 3. The brush caps are visible from the side of the motor. They look like the head of a large slotted (flat-head) screw. Use a flat-head screwdriver to remove the brush caps. 4. Remove the brush cap assembly and replace the old brush with the new brush. Make sure the brushes are clean and slide freely in their guides. 5. Replace the brush assemblies and brush caps. Re-install the motor to the jointer.
