Blade Tracking Adjustment
Blade tracking has been set at the factory and should
require no adjustment. If a tracking problem occurs,
adjust the machine as follows:
Since tracking can only be adjusted while machine is
running, it is suggested that this adjustment be
accomplished by qualified personnel that are familiar
with this type of adjustment and the dangers
associated with it.
1. Disconnect machine from the power source.
2. Raise saw arm to its highest position and close
cutting pressure control valve to hold saw arm in
place.
3. Locate tracking adjustment plate on the back side
of the driven blade wheel.
4. Loosen the three bolts (A - Fig.5) located on the
top of the tracking nuts.
5. Tracking adjustment is accomplished by either
loosening or tightening three adjusting nuts (B -
Fig.5).
6. Tracking is set properly when the back of the
blade lightly touches the wheel flange.
Note:
over-tracking (allowing blade back to rub hard
against wheel flange) will damage the blade
wheels and blade.
7. Tighten locking bolts (A) once properly tracking is
completed.
8. Connect machine to the power source.
Adjusting Feed Rate
When the oil regulating micro switch (A) Fig.6 is
turned clockwise as far as it will go, the saw frame 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
frame 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.
