BLADE INSTALLATION
WARNING!!!
Gloves must be worn when changing the blade.
4/11/2007 6
WARNING!!!
Electrical supply must be locked out when changing the blade.
Blade selection is based on the many factors and complexity of the work to be cut.
The blade placed on the band wheels with teeth facing toward the operator and down toward the
top of the worktable. Tension the blade to remove slack. Rotate the wheels by pushing the jog
button to ensure tracking is correct, and blade will not “pop” off when machine is started. If tracking
is incorrect, adjust before starting machine.
BLADE TRACKING
Note: This alignment is factory set, but may need an adjustment after replacing the blade.
his machine has a bottom wheel that drives the saw blade and a top idle wheel that is adjustable
T
to facilitate blade tracking. The edges of the wheels are fitted with a composite material to
accommodate the tooth set.
First remove the blade tension by loosening the black hand wheel. The idle wheel may be adjusted
by loosening the silver knurled locking collar and turning the black knob in the center of the wheel.
Turning the knob in a clockwise manner runs the blade toward the back edge of the band wheel. A
counter clockwise movement will move the blade toward the front edge of the band wheel (see
picture on below).
WARNING!!!
Before performing the procedure below be sure the wheel safety doors are closed.
To rotate the wheel to find out where the blade is on the wheel, be sure both wheel doors are
closed and push the power start button then turn the run / jog button to jog, now push and hold or
push the jog button to rotate the blade slowly. This will help identify which way to adjust the wheel
adjustment.
Correct tracking takes place when the blade runs approximately in the center of the wheel.
NOTE: The main casting with adjusting screws have been preset at the factory during assembly
utilizing special fixtures. No adjustment should be attempted.

Black hand wheel
Blade tension indicator
BLADE TENSIONING
The blade indicator is located inside the upper wheel compartment, on the lower left side of the idle
wheel. (See picture above) 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”,
and 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 zero. As tension is applied to the blade the
needle will move accordingly, and should be tightened until the correct blade width is indicated on
this gauge. Example: Installing a 1/2” blade on the machine, tighten the hand wheel until the
indicator’s arrow is pointing to the 1/2” mark on the scale. Before starting the machine, check the
blade tracking by pushing the jog button for one or two seconds.
This indicator has been calibrated at the factory. If recalibration is ever needed follow the steps
below:
Using a blade tension gauge, (many times the company that you purchase blades from can furnish
you with this gauge) tension the blade to the proper PSI. The PSI will very from blade types
(carbon, Bi-metal) and blade widths. This information can be obtained from your blade supplier.
When proper tension is achieved, loosen the setscrew in the collar on the tensioning wheel shaft.
(See figure 6 above) Adjust this collar up or down on the shaft until the arrow is pointing to the
corresponding blade width. On the indicator. Tighten setscrew.
Note: It is better to over tension the blade than to run it under tensioned.
BLADE GUIDES
ARNING!!!
W
Gloves must be worn when handling or adjusting the blade guides.
WARNING!!!
Electrical supply must be locked out when adjusting or changing blade guides.
Your machine has come equipped with a set of interchangeable “V” type blade guides. A
set of guides consist of two each left hand and two each right hand guide inserts. The
standard guides furnished are 10 / 12 mm guides. Other sizes are optional, and can be
purchased separately, or as a five piece set. The five-piece set includes 3 / 4 mm (1/8 1/4”) 6 / 8 mm (5/16 - 3/8”) 10 / 12 mm (standard set 1/2 - 5/8”) the blade width will dictate the
size blade guide to be used.
Note: N
narrower than guide insert. Damage will occur to guide insert and blade. Blade insert must
correspond with blade width.
ever use blades larger than the rated capacity of the machine. Never use blades
4/11/2007 8
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 above) and support the blade equally on each side. A couple of thousands on each side of
the blade will provide the running clearance and support for contour sawing.
Note: Chips should be removed from the blade guides during each blade change or
more frequently if required.
BLADE GUIDES
The back end roller that supports the back of the blade on each guide holder contains a hardened
cap over a set of ball bearings. This should be checked periodically for free movement so it is
allowed to rotate freely as the back of the blade comes in contact with the face of this roller.
Noticeable friction in this assembly indicates it should be replaced. This can be done by removing
the right hand guide insert, moving the left hand guide up away from the bearing face. Loosen the
setscrew on the bottom of the guide holder and sliding the old bearing and shaft out and a new one
in. Tighten the setscrew and re-adjust the guides. See graphic below.
The “V” type solid blade guides and holder assemblies as furnished standard with the machine and
are recommended for the majority of cutting applications.
BAND SPEED SELECTION
The saw blade is driven by a direct drive transmission. On the front panel you will see the surface
feet per minute read out (see chart for proper blade selection).
