WARNING

Disconnect machine from the power source

before adju sting or changi ng vise po sition!

Failure to compl y may cause seri ou s in ju ry!

Adjusting Vise Square to the Blade

Position A

1. Place a machinist' s square on the bed

against the blade and the vise. The square
should lie along the entire length of the vise
and blade without a gap.

2. If adjustm ent is necessary, loosen bolts (A,

Fig. 5) holdi ng the vise and adjust vise so
square lines up properl y . Tighten bolts.

3. You may want to perform a test cut. Cut off

the end of the stock. Make anot her cut so
that you have an accurat e sect ion to
measure. Measure thic k ness wit h c alipers.

Adjusting Vise for Miter Cuts

Position B

1. Move the vi se into the second set of

threaded holes (B, Fig. 5) by removing hex
cap bolts (A, Fig. 5).

2. When angle has been set ti ghten bolts.

3. Adjust other jaw.

4. There is an angle label on the backside of

the bed. This is for ref er enc e only. Chec k
angles with a machi nist’s prot r ac tor.

For your own safety: only use position B for
miter cuts. Vise square to the blade, in position
B would expose more of the blade, ri ght of the
vise, than is necessary for the cut.

Positioning Vise

To position the m ov eable v ise:

1. Pull up on the rack block (C, Fig. 5).

2. Move vise to desired l oc ation by sliding

along bed.

3. Tighten vi se by turning handwheel, found at

the left end of the bed, cloc k wise.

4. Loosen vise by turning handwheel counter-

clockwise so you can pull up on the rack
block.

Changing Blade Speeds

Adjust the vari able blade speed only while the
machine is running. The dial (A, Fig. 6) sticking
out of the belt cover (right side) controls the
variable speeds between 66 F P M to 264 F PM.

Semi-Automatic Arm

Preset the height, which the arm stops when it
raises automati c ally. The height the arm raises
depends upon the piece you want to cut. The
limit switch is l owered or r aised by loosening a
locking handl e ( A, Fig. 7). Tight en the locking
handle when the limit switc h has been properly
adjusted.

Automatic Shut-Off

The blade will stop after the material has been
cut, and the arm reaches it s l owest position.
The arm will automatically rise to the preset
height.

Adjusting Feed Rate

Rate of downfeed is adjusted by turning the
downfeed knob on the contr ol panel. Rate of
feed is important to bandsaw performance;
excessive pressure may break the blade or stall
the saw. Insufficient pressure rapidly dulls the
blade.

Material c hips or shavi ngs are t he best indicator
of proper speed and downfeed. The ideal chip
is thin, tightly curled, and warm to the touch.
Chips that range from golden brown to black
indicate excessive force. Blue chips indicat e
extreme heat from too high a band speed, which
will shorten blade life. Thin or powdered chips
indicate insuff icient downfeed rate.

A detailed explanation on feed rate can be found
in the enclosed "Guide to Band Sawing"
published by Ameri c an S aw and Manufacturing
Company. Reprinted by permission.

Blade Tracking Adjustment

Since tracking c an 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.

Blade tracking has been set at the factory and
should require no adjustment. If a tracking
problem occur s, adjust the machine as follows:



WARNING

Tracking adju st ment is done with the wheel

covers open to observe the blade. Use
extreme caution so as not to come into

contact with the blade!

1. Raise saw arm to its highest position.

2. Locate tracki ng adjustment plate on the

backside of the idle wheel.

3. Loosen the three bolts (A , Fig. 12) located

on the top of the tracking nuts.

4. Tracking adj ustm ent is accomplished by

either loosening or tightening three adj usting
nuts (B, Fig. 12).

5. Tracking i s 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.

6. Tighten loc ki ng bolts (A) once proper

tracking i s completed.

Lubrication and Gearbox

All ball beari ngs are perm anently lubricated and
sealed. They requir e no further lubrication.

The gearbox lubri c ant should be changed after
the first 3 mont hs of operation. Use Mobil SHC
634, or equivalent . Change lubricant from then
on every year.

To check level of gear box lubr ic ant, place arm
in down position and allow a few minutes to
pass so that oil drains down. Check level in
sight glass on side of gear casing. Cor r ect lev el
is the dot in the middl e of sight glass.

Hydraulic Pump

If you need to add hydraulic fluid to the tank
remove cap (A, Fig. 13). Add Mobil DTE 24
until the black ball floats to the full positi on.

Coolant Pump

The coolant tank should be filled with 6 gallons
of a cutting cool ant. Fill by pouri ng c oolant into
the chip tray. Add cool ant in the same manner
when coolant is low. To drain coolant remove
hex cap screw (A, Fig. 14). Follow all coolant
manufacturer’s instructions for safety, mixing
disposal, etc.
The spray nozzle (B, Fig. 14) enabl es the user
to wash chips out of the way. Ther e are thr ee
ball valves that control the coolant distri bution to
the spray nozzle and eac h blade guide.

Replacing the Variable Speed Belt

Disconnect the machine from the power source.
Take the belt cover off by remov ing the knob
and washer. Loosen tension on the belt by
turning the variable speed dial (A, Fig. 15) to the
lowest setting. This will allow you to remove the
