2.
To center blade between the lower blade thrust bearings, use the crescent wrench
on the bearing stems to move them either to the right or left until blade is centered
between them.
3.
To adjust blade depth on the lower blade guides, loosen hex bolts located behind the
lower blade guide block (Fig. 15-A). Move block to position blade
thrust bearings. Retighten hex bolt to lock into position.
NOTE: Blade should not touch thrust bearing until pressure is applied to material being cut.
F. Replacing Blade Guides
Replacing blade guides is necessary after considerable wear. All Diamond Tech's
Replacement Guides can be purchased wherever Diamond Tech products are sold
or by calling 800-937-9593.
G. Changing Blades
1.
Turn power to the OFF position. Disconnect the machine from the power source and
open the front panels of the saw.
2.
Release blade tension by turning the blade tension knob counter-clockwise (Fig. 9). Remove
the table alignment screw and wingnut on the front of the cutting table (Fig. 3).
3.
Slide used blade off upper and lower wheels.
4.
Install new blade with the diamond coated edge facing the front of the saw. Slide blade through
the slot in the table, over the lower wheel and then up over the upper wheel.
5.
Retighten the blade tensioning knob (Fig. 9), making sure the blade is centered on the
top wheel (Fig. 11). Manually turn wheels to ensure proper tracking before closing front
panels. Refer to section B if blade alignment needs adjusting.
Note: Breaking blades is the most common problem encountered by new band saw
owners. This is often caused by over tightning the blade or forcing the work material
into the blade. To prevent this from occuring, slowly coax materials into the
blade, maintaining a forward movement of the material at all times.
H. Drive Belt Tension Adjustment
A loose drive belt may result in a noticeable loss of power to the blade wheels.
1.
To tighten the drive belt, turn saw OFF and unplug the saw from the electrical outlet.
2.
Remove all screws securing rear panel encasing the drive belt (Fig. 16).
3.
Loosen all four motor mount set screws using a large hex wrench (Fig. 17).
4.
