GENERAL

Grizzly Industry 6” Heavy – Duty Jointer, Model G0858

• 1 H.P. TEFC motors driving a three-knife cutter-head at 5000 R.P.M.
• The knives are high speed steel, able to re-sharpen, and are adjusted by means of jack screws or springs, making blade setting quick and easy.

Maintenance

REGULAR MAINTENANCE: To ensure its optimum performance. Inspect the Jointer prior to use. Check for the following conditions and repair or replace when necessary.

1. Mounting bolts may loosen with use, assure that they are tight.

2. Check switch for wear.

3. Check for wear or damaged cords and plugs.

4. Check V-belt for wear and damage.

5. Check other conditions that could hamper the safe operation of this machine.

6. Since bearings are shielded and permanently lubricated, simply leave them alone until they need to be replaced. Do not lubricate them.

7. 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. Re-assemble and reset the gibs.

8. Inspect regularly for tension and wear; replace when necessary with a size A-36 belt. Check pulleys to ensure that they are properly aligned. See pulley/V-belt sections for proper tension and pulley alignment procedures.

ADJUSTMENTS

Table Gibs: The function of the gibs are to allow precise adjustment of the table movement along the dovetail ways. Adjustment of the gib will dictate how easy it will be to move the tables up and down with the levers or hand wheels. To adjust gibs: 1. Unscrew the upper and lower check nuts on the infeed table several turns, leaving the lock handle tight. See Figure 14. 2. With one hand securely on the lever bar, loosen the table lock handle and adjust the upper and lower gib setscrews until table movement is smooth and controlled. 3. Once the gib has been properly adjusted, tighten check nuts and repeat Steps 1-2 for the outfeed table. 4. Make sure there is no side-to-side movement of the tables once the check nuts have been tightened. If there is, repeat Steps 1-4.

KNIFE INSPECTION: The knives of your jointer must be periodically replaced or adjusted. Adjustments should be as precise as possible with tolerances within .002"- .003" to prolong the sharpness of the knife edges. Improperly adjusted knives can unbalance the cutterhead and shorten bearing life, as well as produce substandard jointing or planing results. The knives are set at the factory using jack screws before shipping. Springs are also included in the cutterhead supplied with your machine. They may be used instead of the jack screws depending on your preference. Now is a good time to double-check the knife settings. To inspect and adjust knife set: 1. Unplug the jointer! 2. Remove the upper cover or cutterhead guard to expose the top of the cutterhead. 3. Carefully turn the cutterhead (using the pulley) until the first knife is at top dead center. 4. Using the knife setting gauge, check the knife height. The jig should sit solidly with both feet on the cutterhead. See Figure 15. If the knife is adjusted properly, the contact point at the center of each adjuster should just touch the tip of the knife. If the knife does not make contact, or if the knife causes the adjuster’s legs to not seat on the cutterhead, the knives need to be adjusted.
