gear box the oil inside the gear reducer should be replaced after the first month (160 hours) of regular use. we recommend 90 wt. gear oil. After the first oil change, the oil inside the gear reducer should be replaced after every 2500 hours of use. we recommend 90 wt. gear oil. -24- g0524 rip Saw v-belts lube system inspect V-belts for damage or cracks after every month (160 hours) of regular use. bearings the sealed ball bearings in this machine are permanently sealed and lubricated. there is no need to lubricate them. if the bearing wears out, simply replace it with one ordered from our service department. the lube reservoir (figure 25) houses the oil that lubricates the conveyor track. the oil is pumped through a series of plastic tubes at a rate of 3-6 cc every 5 minutes, and onto a brush under the main table. when the oil level in the reservoir becomes low, a switch is triggered that prevents the saw from being operated. if this occurs, fill the reservoir above the “low” line and the saw will operate normally. figure 25. lube reservoir. g0524 rip Saw -25 maintenance log date approximate hours of use maintenance performed -26-g0524 rip Saw section 8: service adJustments always disconnect power to the machine before performing service adjustments. failure to do this may result in serious personal injury. about service this section is designed to help the operator with adjustments that were made at the factory and that might also need to be made during the life of the machine. this section is provided for your convenience— it is not a substitute for the grizzly Service Department. if any adjustments arise that are not described in this manual, then feel free to call the grizzly Service Department at (570) 546-9663. Similarly, if you are unsure of how to perform any procedure in this section, the grizzly Service Department will be happy to guide you through the procedures or help in any other way. fence alignment if the face of the fence is not parallel to the saw blade (cut line), the resulting rip cut will yield a workpiece that is wider at one end or the other. to adjust the fence alignment: 1. rip cut a scrap workpiece. 2. Measure the width at each end of a workpiece that has been cut on the rip saw. — if end A is wider than end B, then the tip of the fence needs to be adjusted to the left to make the fence parallel to the blade (figure 26). A B figure 26. Adjusting the fence to the left. g0524 rip Saw -27 — if end B is wider than end A, then the tip of the fence needs to be adjusted to the right v-belt tension to make the fence parallel to the blade (figure 27). A B figure 27. Adjusting the fence to the right. 3. loosen the cap screws (figure 28) on the top of the fence to allow adjustment of the fence. retighten when complete. Cap Screws figure 28. Cap screws to loosen fence. 4. repeat step 1 to verify that the adjustments are correct. to adjust the main motor v-belt tension: 1. disconnect the saw from the power source! 2. remove the side access panel to reveal the adjustment mechanism. 3. loosen the jam nut (figure 29). Jam Nut turnbuckle figure 29. Arbor motor V-belt adjustment. 4. Adjust the turnbuckle to increase or decrease the V-belt tension. Note—Turning the turnbuckle clockwise lowers the tension and counterclockwise increases it. 5. retighten the jam nut when the V-belt has been tensioned correctly and re-install the side access panel. -28- g0524 rip Saw to adjust the feed motor v-belt tension: fence ride height 1. disconnect the saw from the power source! 2. remove the side access panel to reveal the adjustment mechanism. 3. loosen the jam nut (figure 30). figure 30. Feed motor V-belt adjustment. Adjustment Nut Jam Nut 4. raise or lower the adjustment nut to change the V-belt tension. Note—Raise the adjustment nut to decrease the tension and lower it to increase the tension. 5. retighten the jam nut when the V-belt has been tensioned correctly and re-install the side access panel. to adjust the ride height of the fence: Adjust the setscrew (figure 31) to raise and lower the ride height of the fence. Note—The fence could scratch the cast iron table surface if the ride height is set too low. figure 31. Fence ride height adjustment. g0524 rip Saw -29 5. Each pressure roller can be independently pressure rollers adjusted by loosening the jam nut and turn- the pressure rollers must all be the same distance away from the table surface (conveyor track). to adjust the pressure rollers: 1. disconnect the saw from the power source! 2. Using the blade height handwheel, raise the bottom edge of the blade above the bottomdead- center of the pressure rollers. 3. Using the pressure roller height handwheel, raise the head of the saw high enough to allow a flat board to be placed under all the the pressure rollers. 4. Slowly lower the head. — if the pressure rollers make contact with the board at the same time, they are adjusted correctly. — if the pressure rollers do not make contact with the board at the...
