3. Please refer to the section titled Blade Changes on page 25 to install the blade. 4. Tension the blade enough to keep it on the saw so it does not spring off during the rest of the assembly process. 3. Place the large hex bolt with washer through the table trunnion mount and the trunnion. The assembly should now look similar to Figure 6. DO NOT connect power to the bandsaw until instructed to do so. Failure to do this may result in serious personal injury. Dust Port Guide Post To install the dust port: 1. Place the dust port on the saw as shown in Figure 8. 2. Secure it with the included Phillips head screws. Figure 8. Dust port installed. The rack and pinion guide post can be easily raised and lowered. To adjust the guide post: 1. Loosen the guide post lock knob indicated by the arrow in Figure 9. 2. Turn the guide post handwheel. 3. Tighten the lock knob. Because the blade guard and the entire upper blade guide assembly are attached to the guide post, these items move up or down with the guide post. Figure 9. Guide post lock knob. -14- 18" & 20" Super Heavy-Duty Bandsaws Blade Guard The blade guard can be adjusted along the support rod to help facilitate adjustments made to the blade guide assembly. The blade guard must be adjusted to the lowest position on the support rod before starting the machine. To move the blade guard: 1. Loosen the hex bolt shown in Figure 9 that secures the blade guard bracket to the guide post. 2. Move the blade guard up prior to making adjustments to the guide bearing assembly, or down, prior to using the machine. 3. Align the slot in the front of the guard with the blade and tighten the hex bolt that secures the it to the guide post. Figure 10. Blade guard mounting bracket. Blade Guides Always adjust the upper and lower blade guides away from the blade before removing, installing or tracking a new blade. To adjust the blade guides: 1. Loosen the 4 knurled jam nuts (the upper guide assembly is shown in Figure 11) that lock the adjusting knob for the guide bearings in place. 2. Rotate the knurled adjuster knob counterclockwise. 3. Loosen the hex bolt for the back bearing and slide it back. This will allow the blade to be removed or tracked without interference. 4. After the blade tension and the blade tracking are set correctly, follow the “Guide Bearing” and “Support Bearing” instructions in this section for adjustment details. Figure 11. Loosen the jam nuts on both sides of the guide block assembly to release the blade guide adjusting knobs. 18" & 20" Super Heavy-Duty Bandsaws -15 Blade Tracking Gullet Line Always adjust the blade guides away from the blade before making blade tracking adjustments. The wheels on the Model G0506/G0507/G0511 Super Heavy-Duty Bandsaws are crowned and have rubber tires. This style requires center blade tracking for proper operation. To adjust blade tracking: 1. Open the upper wheel cover door. Slowly rotate the upper wheel and watch where the blade rides on the wheel. If the blade stays centered on the crown of the wheel, then it is properly tracked. 2. If the blade does not ride centered on the crown of the wheel, then spin the upper wheel by hand and adjust the tracking hand- knob shown in Figure 12, until the blade is positioned correctly. 3. Spin the wheel approximately three more times to ensure that the blade stays centered. Adjust and check if necessary. 4. Close the upper wheel cover door. -16 Jam Nut Figure 12. Loosen the jam nut. Turning this handwheel clockwise will move the blade further into the saw body. Before further adjustments can be made to the guide assembly, the guide bearings must be set even with the “gullet line.” This is the inside edge of the gullets for the bandsaw teeth. To adjust blade guides to the gullet line: Figure 13 shows the edge of the guide bearings set even with the gullet line. A white line (A) has been superimposed to the photo and the blade guard has been moved for clarity. 1. Loosen the hex bolt on the right side of the guide assembly (B). 2. Move the assembly in or out until the edge of the guide roller is even with the gullet. If the back bearing interferes with this, loosen the lock bolt (C) and slide it back. 3. Tighten the bolt for the guide assembly. 18" & 20" Super Heavy-Duty Bandsaws A B C Figure 13. Adjust the guide assembly so the guide bearings are even with the “gullet line.” Support Bearings The support bearings support the back of the blade during the sawing operation. The adjustments that can be made to the support bearings are lateral placement and backing placement. Make sure the guide bearings are adjusted away from the blade before making this adjustment. Figure 14 shows the upper support bearings. Figure 15 shows the lower assembly. When making adjustments to the lower bearing the assembly will move up and down as it moves from side-to-side. To adjust the lateral placement: 1. Loosen the hex bolts (shown in Figures 14 & 15) that allow the assembly to move side- to-side. 2. Shift the...
