OPERATION (CONTINUED)
REMOVING AND INSTALLING THE BLADE
When your machine was shipped, a blade was supplied and
assembled to the saw. When selecting a new blade refer to page 4
and 5 for information on blade selection. The machine requires a
blade 1˝ x 135 ˝ long.
1. Disconnect the machine from the power source.
2. Raise the saw bow about 6˝ and close the feed control valve by
turning it clockwise as far as it will go. (Do not over-tighten.)
3. Open both wheel covers and clean the chips out of the machine.
4. Release blade tension by turning the blade tension hand wheel
(Figure 3, page 6) counter-clockwise.
5. Slide left blade guide arm to the right as far as possible.
6. Remove the blade from both wheels and out of each blade
guide.
7. Make sure the teeth of the new blade are pointing in the
direction of travel. If necessary, turn the blade inside out.
8. Position the blade on the wheels and feed through the upper
blade guard (Figure 3)
9. Put light tension on the blade and work it onto both wheels.
IMPORTANT:
Make sure that the back of the blade is against the
wheel flanges of both wheels.
10. Work the blade all the way up between the blade guide bearings
with the back of the blade against the back-up bearing, as shown
in Figure 4.
NOTE: If bearings need adjustment, refer to the section Adjusting
Blade Guide Bearings, page 6.
11. When you are sure the back of the blade is against the wheel
flanges of both wheels and properly inserted into the guides,
finish putting tension on the blade. Proper tension is achieved
when the pointer is on the left mark of the blade tension scale
behind the idler wheel.
12. Jog the power "Start" and "Emergency Stop" (E-Stop) to be sure
the blade is in place and tracking properly. If blade is not tracking
properly refer to the section Blade Tracking Adjustment, page 6.
STARTING AND STOPPING THE MACHINE
Refer to Figure 5.
The saw bow must be in the raised position before starting the
machine. The machine is started by pushing the Start button and will
continue to run until the saw bow is in the down position at the end
of the cut, or when the Emergency Stop button (E-stop) is pushed.
Pushing the E-stop button will stop the motor at any time.
BLADE TRACKING ADJUSTMENT
The blade is tracking properly when the back of the blade is against
the wheel flanges of both wheels. If the back of the blade is not
against the wheel flanges, tighten or loosen screw (Figure 4), until
the blade is tracking properly.
ADJUSTING FEED RATE
Refer to figure 6.
When the feed control valve is turned clockwise as far as it will go,
the saw bow will not move down. By turning the feed control valve
counter-clockwise, you regulate the flow of oil from the cylinder and
determine the speed at which the saw bow will lower and the blade
will feed through the work. Too many factors are involved to make
tabulated data practical on feed rates. As a general rule, an even
pressure without forcing the blade gives best results. Avoid forcing
the blade at the start as this may shorten blade life and produce a
bad cut. By inspecting the chips while the cut is being made will
indicate whether the feed rate is correct. Fine powdery chips indicate
a feed rate which is too light. The teeth are rubbing over the surface
instead of cutting. Burned chips indicate excessive feed which causes
the teeth to break off as the blade overheats. The ideal feed rate is
indicated by chips that have a free curl and this will give the fastest
cutting time and longest blade life.
