1.Check Coolant: Low coolant level causes
foaming and high blade temperatures. Dirty or
weak coolant can clog pump, causes crooked
cuts, low cutting rate and permanent blade
failure. Dirty coolant causes the growth of
bacteria with ensuing skin irritation.
2.Keep vise slides clean and oiled.
3.Clean chips from blade wheels and wheels
housing.
6.Blade Speed: Make sure the blade speed sets
correctly for workpiece material and shaped.
THE SELECTION OF SAWBLADES
Remarks: HSS-High Speed Steel Sawblade
HCS-High Carbon Steel Sawblade
7.Check Blade Tension: Particularly after initial cuts
with a new blade.
Blade Selection
A. Never use a blade so coarse that less than 3
teeth are engaged in the workpiece at any time.
(Too few teeth will cause teeth to strip out.)
B. Never use a blade finer than required to obtain a
satisfactory surface finish or satisfactory flatness.
(Too many teeth engaged in the workpiece will
prevent attainment of a satisfactory sawing rate;
frequently cause premature blade wear;
frequently produce “dished” cuts or the cuts are
neither square nor parallel.)
C. The chart which follows is not expected to be
exactly correct for all cases. It is intended as a
general guide to good sawing practices. Your
blade supplier or the qualified engineers should
be your most reliable source of correct
information for operational details of saw blades
and their use.
NOTE:
1. When cutting standard wall pipe, tubes, channel
iron, angle iron, and I beam, a 10 pitch saw blade
of wave-set type or sawblade of (HSS) 6/10T is
frequently used for good advantage.
2. Tubes or structure with wall thickness or web
thickness of 1/2” or more usually uses an 8 or 6
pitch blade or sawblade of (HSS) 4/6T
satisfactorily.
3. When rectangular solid bar is to be sawed, the
work should, whenever possible, be loaded with
the thinnest cross section exposed to the blade
teeth. The pitch (or number of teeth per inch of
blade) selected must provide engagement of at
least 3 teeth in the workpiece. Should application
of this rule not be possible because the thinnest
cross section is too thin, the piece must be loaded
with the wider dimension exposed to the saw
teeth and a coarser blade selected from the listing
of recommendations for round and square solid
bars.
Single Phase
8
Refer to the wire drawing inside the electrical box and
above for proper motor and transformer connections,
lead selection and wiring connections from the motor
to the power source for the voltage you are using.
Three Phase
Refer to the wire drawing inside the electrical box and
above for proper motor and transformer connections,
lead selection and wiring connections from the motor
to the power source for the voltage you are using.
Important: Immediately after wiring the machine,
remove the drive belt, turn on the power and make
sure the motor is running in the right direction
(clockwise when looking at the motor shaft.) If it is not,
disconnect the machine from the power source and
interchange any two lead lines.
General Operating Instructions
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 the selection of sawblades. The
machine requires a blade 1”×0.032”×130”.
(27MM×0.9MM×3300MM)
1. Disconnect the machine from the power source.
2. Raise the saw frame about 6” and close the feed
control valve by turning it clockwise as far as it will
go. (Do Not Overtighten.)
3. Open both wheel covers and clean the chip out of
the machine.
4. Release blade tension by turning the blade
tension handwheel (C) Fig.1 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. Place the blade in place on the wheels (A) and
through the upper blade guard. (B) Fig.1.
9. Work the blade all the way up between the blade
9
guide bearings with the back of the blade against
the back-up bearing, as shown in Fig.2.
Note: If bearings need adjustment, refer to the
section adjusting blade guide roller
bearings.
10. Put light tension on the blade and work it on both
wheels, as shown in Fig.3. Make sure that the
back of the blade is against the wheel flanges of
both wheels. This is very important.
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
fly wheel.
12. Jog the power “on” and “off” to be sure the blade
is in place and tracking properly. If blade is not
tracking properly refer to the section tracking the
blade.
Starting and Stopping the Machine
The saw frame must be in the raised position before
starting the machine. The machine is started by
pushing the start button (A) Fig.4, and will continue to
run until the saw frame is in the down position at the
end of the cut, or when the stop button (B) is pushed.
Pushing the stop button (B) will stop the motor at any
time.
Blade Tracking Adjustment
10
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 blade fly 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 can 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 chip while the cut is being made will
indicate whether the feed rate is correct. Fine powdery
chip indicates a feed rate which is too light. The teeth
are rubbing over the surface instead of cutting.
Burned chip indicates excessive feed which causes
the teeth to break off as the blade overheats. The
ideal feed rate is indicated by chip that have a free
curl and this will give the fastest cutting time and
longest blade life.
Adjusting Blade Guide Brackets
11
The blade guides should be set as close to the vise
jaws as possible. The right blade guide bracket, is not
adjustable and is set at the factory to clear the right
hand vise jaw. The left blade guide bracket can be
moved to the left or right depending on the size of the
workpiece. To move the left blade guide bracket (A)
Fig.7, loosen the knob (B), position blade guide
bracket and tighten knob (B).
Automatic Shut-Off Adjustment
The motor should shut off immediately after the blade
has cut through the material and just before the head
comes to rest on the horizontal stop bolt. If the
machine continues to run after the workpiece has
been fully cut, locate and adjust the micro switch
mounting plate down. If the machine shuts off before
the workpiece has been completely cut, move the
micro switch mounting plate up.
Thrust Roller Adjustment
1. Disconnect machine from the power source.
2. Loosen two hex socket cap screws (A-Fig.8).
3. Move guide seat (B – Fig.8) up or down until a
clearance of 0.003” to 0.005” between back of
blade and thrust roller is obtained.
4. Tighten two hex socket cap screws (A – Fig.8).
5. Repeat for other blade guide assembly.
6. Connect machine to power source.
Guide Roller Adjustment
1. Disconnect machine from the power source.
2. Loosen blade guides (A – Fig.9) by loosening
screws (B). Slide blade guides away from blade.
3. Loosen locking screws (C) by using a hex wrench.
4. Adjust the eccentric bushings with a combination
wrench until the ball bearings are snug to the
blade. Note: blade should travel freely up and
down between the ball bearings. Do not pinch the
blade.
5. Tighten locking screws (C).
6. Slide blade guides back into contact with blade
and tighten screws (B).
7. Connect machine to the power source.
Vise Adjustment
12
To position the moveable vise jaw:
1. Turn vise handwheel (A – Fig.10) 1/2 turn
counter-clockwise.
2. Move rack block (B – Fig.10) to desired location
by sliding along the bed. Place the rack block
onto the rack.
3. Turn the handwheel to tighten the vise.
To adjust the vise for angle cutting:
1. Loosen bolts and move vise jaw (C – Fig.10) to
desired location.
2. Set the vise to desired angle, reinstall nuts and
tighten the nut and bolt assemblies.
3. Make sure the movable vise jaw parallels to the
fixed vise jaw. Loosen the bolt (D – Fig.10) and
adjust it until it is in parallel with the fixed vise jaw
and tighten the bolt.
Setting Up the Machine for Operation
1. Select the proper speed and blade for the type of
material you are going to cut.
2. Make sure blade tension is adjusted properly.
3. Lift the saw frame up and turn off the oil regulating
micro switch.
4. Place the stock between the vise jaws, set the
stock for the desired length of cut and tighten the
vise.
5. Make sure the left blade guide bracket (A) is
adjusted as close as possible to the left vise jaw
(B) Fig.11.
6. Turn the oil regulating micro switch (C) Fig.11,
counter-clockwise until the saw blade begins to
lower by the desired rate.
7. Proceed to cut through the workpiece, as shown
in Fig.11. The machine will shut off upon
completion of cut.
