4/29/03 WHEEL ALIGNMENT V-16 & V / VH-24 Note: This alignment is factory set, but may need adjustment when replacing blade. Two wheel machines have a bottom wheel that drives the saw blade and a top idle wheel that is adjustable to facilitate blade tracking. The edges of the wheels are fitted with a composite material to accommodate the tooth set. The idle wheel may be adjusted by loosening the knurled locking collar and turning the black knob in the center of the wheel. Turnin

4/29/03 BLADE TENSIONING The blade indicator is located inside the upper wheel compartment, on the lower left side of the idle wheel. (See machine features graphic) The indicator has an arrow mounted on the horizontal plane, with a corresponding scale for blade tensioning. The scale has two legends, one reads inches from 0 - 1”, the second reads mm 0 - 25 mm. This allows tensioning either standard or metric blade widths. With out tension on the blade, the indicator should read

4/29/03 An analysis of the work to be performed should be made and the proper blade selected. The blade should always be inspected before installing on the machine. Things to look for should be the smoothness on the sides and back edge of the weld, look for any missing teeth, or impacted chips. The blade guides may now be selected and inserted into both the upper and lower guide holders. Proper adjustment of these guides takes place when they form a complete “V” shape (see graphic

4/29/03 HIGH SPEED ROLLER GUIDES Applications and Advantages: Friction and abrasive cutting, filing operations, aluminum and woodcutting. These guides eliminate having to change inserts when changing to blades of different widths. Requirements for Installation: These roller guides must be installed using a new 1/2” blade width band for proper alignment. The 1/2” band should be tracked within the approximate center line of the band wheels. Note: Be certain band wheels are c

4/29/03 Repeat this process for the lower guide assembly. Note: Upper guide stud may be adjusted in or out in the guide post to allow proper clearance for blade, and for alignment with lower guide. Align backup bearing as previously described for upper guide. Tighten both set screws when alignment is confirmed. Re-adjust side rollers. (Graphic in previous column) Set the side clearance distance between rollers and saw blade, leaving about a .004 gap. Note: If the adjustment s

4/29/03 Note: Occasionally the drive wheel may have to be jogged by hand to engage the transmission lever. The variable speed is achieved through the use of a variable regulator. (Figure 3) This is turned clockwise or counter clockwise to obtain an increase or decrease in blade speed, in either range. Adjust until desired speed is reached as read on the blade speed gauge. (Figure 4) WARNING: DO NOT ADJUST THE VARIABLE SPEED CONTROL (FIGURE 3) SPEED
