    Use the dial indicator whenever the instructions call for use of the gauge block and/or feeler gauge. Refer to the current Grizzly catalog for dial indicators. Figure 11. Guide block specifications. WARNING DO NOT make adjustments while the planer is running.

  • Page 18: Knife Inspection

    Figure 13 Cap screws for column adjustment. -18- Knife Inspection The Model G1021 Planer has a three-knife cut- terhead. The cutterhead is located in the head casting and rotates on two sealed bearings. No lubrication is needed for the life of the bearings.

  • Page 19: Knife Adjustment

    Improper knife height adjustment can result in damage to knives, poor planer per- formance and possible operator injury. G1021 15" Planer Knife Setting The process of setting the knives in the cutter- head will come into play whenever you sharpen or replace, or after determining that setting is necessary during the initial setup.

  • Page 20: Chip Breaker

    Figure 16. Tightening knives in cutterhead. Chip Breaker The chip breaker is located on the top side of the planer and extends down around the front of the cutterhead. Its function is to prevent tear-out or deep, unregulated gouging as the knives remove material.

  • Page 22: Feed Roller Pressure

    TO ADJUST ROLLER PRESSURE: Disconnect the machine from the power source. Ensure that knives and feed rollers are set correctly. Unscrew the four large pressure setscrews on top of the planer body. See Figure 21. Light Pressure Setscrew Regular Pressure Setscrews Figure 21.

  • Page 23: Bed Rollers

    Figure 22. Roller pressure assembly. Bed Rollers The bed rollers ease stock movement through the planer. The height of the bed rollers will vary depending on the types of wood you will be plan- ing. When planing rough stock, set the rollers slightly high to keep the lumber from dragging along the bed.

  • Page 25: Anti-Kickback

    Anti-Kickback The Model G1021 Planer provides an anti-kick- back safety feature. The anti-kickback fingers hang from a rod suspended across the front of the cutterhead casting. The anti-kickback fingers should be inspected regularly. Check the fingers to ensure that they swing freely and easily. See Figure 26.

  • Page 26: Gearbox

    -26- Gearbox The gearbox is located just behind the hand- wheel on the right side of the planer. The gearbox transfers power from the belt-driven cutterhead to the power feed rollers. The two-speed transmis- sion is controlled by a push/pull lever on the right side of the planer.

  • Page 29: Operations

    SECTION 6: Operations WARNING The Model G1021 15" Planer is a powerful woodworking machine, designed and con- structed for professional-quality applica- tions. Because of its powerful motor and razor-sharp knives, the Model G1021 is inherently dangerous and should be operat- ed with considerable caution and respect.

  • Page 30: Power Feed

    Take it slow and easy. The quality of your work will be better and your planer will last longer. Depth Limiter The Model G1021 is equipped with a depth lim- iter – located on the bottom of the cutterhead casting just under the nameplate. See Figure 36.

  • Page 31: Test Run

    Do not allow visitors into your workshop when testing or operating equip- ment. G1021 15" Planer Wood Species The species of wood, as well as its condition, have a dramatic effect on planing ability. The harder the wood (as illustrated by its shear strength), the more difficult it will be to plane.

  • Page 32: Planing Difficulties

    Using a dust collection system in combination with the planer can help reduce chip marks. Inspect the chip deflector and re-adjust as described earlier in the text. G1021 15" Planer...

  • Page 33: Maintenance

    Table The table and other non-painted surfaces on the Model G1021 should be protected against rust and pitting. Wiping the table clean after every use ensures that moisture from wood dust isn’t allowed to trap moisture against bare metal sur- faces.

  • Page 34: Lubrication

    If the bad bearing is not replaced, it will eventually seize - possibly doing damage to other parts of the machine. Bearings are standard sizes and can be replaced through Grizzly. Proper lubrication of other components of the Model G1033 are essential for long life and trou- ble-free operation.
