1. Remove the saw band as described in the previous section.
Clean metal chips and other foreign materials and debris
from around the saw guides and both bandwheels. Remove
the new saw blade’s protective cap if necessary.
2. Form the saw blade into a loop and slip the blade under the
saw guide arms and into approximate position for placement.
With the saw blade’s teeth facing towards you, place the
blade around the drive and idler bandwheels.
3. Twist the saw blade 90° so that its teeth between the saw
guide arms point down and to the right.
4. Insert the saw blade into the saw guide inserts and pull up
against the back-up bearing
5. Check the saw blade’s position around the bandwheels (its
back edge must rest against each bandwheel’s rear flange).
6. Apply correct blade tension by turning the band tension
handwheel clockwise.
7. Turn the saw guide insert adjustment knobs clockwise until
tight (do not over tighten). Turn each adjustment screws back
counterclockwise 1/4 turn.
8. Reposition or mount the band brush and top guard. Close
both bandwheel doors.
OPERATING THE BAND SAW
Keep your hands away from all cutting
edges and moving parts. Never reach
under the saw or workpiece. The blade is exposed in these
areas and the guards cannot protect your body there. Be
alert to the possibility of blade binding and kickback
occurring.
Always wear safety glasses complying
with United States ANSI Z87.1 before
beginning power tool operation.
Before operating the machine, all the main parts of the machine
must be set up correctly as per the directions in the previous
Assembly/Installation Section.
Blade break-in
When cutting for the first time, it is good practice to break in the
blade by making a series of cuts at a low advance speed
(= 12-14 in2/min on material of average dimensions compared
to the cutting capacity and solid section of normal steel with
R = 410-510 Nimm2), Generously spray the cutting area with
lubricating coolant during the break-in.

OPERATING THE BAND SAW - CONTINUED
Making a cut
II JJ KKHH
After your workpiece(s) have been secured and bandsaw
properly adjusted as described previously, you can make your
cut.
1. Push the blade start button (HH)
2. Turn on the coolant flow (II)
3. Set the saw bow descent speed (JJ)
4. Activate the saw bow descent (KK)
5. When the cut is finished the saw will stop. Manually lift the
saw bow.
Saw blade tension
Do not start the blade drive motor without
proper tension on the band saw blade.
LL
1. Blade tension is applied by turning the handwheel
which protrudes from the saw head’s left side (LL). Turn
the handwheel clockwise to increase band tension;
counterclockwise to decrease it.
2. Correct band tension for the machine’s standard one (1) inch
(25.4 mm) wide by 0.035-inch (0.89 mm) saw blade is 27,000
to 30,000 psi (1900 to 2100 kg/cm2).
This tension setting is established when the preset stop
bolt contacts the large washer. An escutcheon near the
band tension handwheel describes the washer to stop bolt
relationship in a setting of 30,000 psi (2100 kg/cm2).
3. Important factors which influence band tension settings are
the size of stock to be cut and desired blade life. General
rules-of-thumb are: (a) Lower tensions will increase saw
blade life; (b) Greater tension is required as spacing is
increased between the saw guide arms; (c) Higher band
speeds require greater tension.
Blade speed adjustment
To prevent damage to the band saw,
speed changes must be made when the
machine is running.
MM
NN
NN
The blade speed is infinitely variable between 125 and 246 fpm.
Use lower speeds for harder materials and high speeds for softer
materials.
1. To adjust, turn the band speed adjusting handwheel (MM) on
the right end of the saw head clockwise to “INCREASE” band
speed. Turn it counterclockwise to “DECREASE” the blade
speed.
2 A speed indicator pointer and scale provided on your
machine will show you the blade speed based on the
handwheel’s adjustment (NN).
Blade brush
OO
A powered blade brush (OO) removes metal particles from the
saw blade teeth. The blade brush is located inside the right
bandwheel door.
The brush must be properly adjusted to clean the blade tooth
gullets without touching the bottom of the gullets for optimum
sawing performance. As bristles wear down, adjust brush position
by loosening the mounting bolts holding the brush assembly
to the bracket on the saw head. Move the brush to the correct
cleaning position and retightening the mounting bolts.
