CALIFORNIA – Proposition 65 Warning
Engine exhaust and some of its constituents, and
some dust created by power sanding, sawing,
grinding, drilling and other construction activities
contain chemicals known to the State of California to
cause cancer, birth defects and other reproductive
harm. Some examples of these chemicals are:
o Lead from lead-based paints.
o Crystalline silica from brick.
o Cement and other masonry products.
o Arsenic and chromium from chemically treated
lumber.
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: ALWAYS work in a
well-ventilated area, and work with approved safety
equipment, such as duct masks that are specially
designed to filter out microscopic particles.

Engine Power, Cutting Power & Sheave Size
The cutting capability of your saw is a relationship between engine power (as
reflected in the engine RPM) and the speed (RPM) of the Blade Shaft. The diesel
engine of the SP-6457 TD runs at 2800 RPM (full load). If 2800 RPM was a
desirable Blade Shaft speed for the average conditions in which you work, we
would use the same size sheave on the engine shaft and the Blade Shaft; and the
ratio between the two would be 1 : 1.
1 : 1
1.4 : 1
Blade Shaft
Engine
Blade Shaft
Engine
Fig. 4 — Blade Shaft Ratios
If, however, for your cutting conditions, you need a Blade Shaft speed slower
than the engine speed (and this is usually the case), then we need to INCREASE
the ratio between the two speeds by putting a larger diameter sheave on the
Blade Shaft. This, in effect, is what occurs when you shift gears on the SP-6457
TD.
If, for example, you know from experience that you need a Blade Shaft speed of
2000 RPM for the size of blade you normally use (see the Blade RPM vs. SFPM
Chart, below):
2800 (engine RPM) ÷ 2000 (desired BS RPM) = 1.4
This is the ratio 1.4 : 1, which means that for every 1.4 revolutions of the engine,
the Blade Shaft only turns once.
Ratios greater than 1 : 1 also have the beneficial effect of increasing the torque of
the Blade Shaft by the same factor (1.4 in our example) . The manufacturer
advertises that the Deutz BF31011 diesel engine develops 123 ft. lbs. of torque.
To find the theoretical torque of our example saw setup:
123 x 1.4 = 172.2 ft. lbs.
Actual torque of the saw will vary somewhat. In general, more torque means
more cutting power.
20
Download from Www.Somanuals.com. All Manuals Search And Download.
Typically, however, the ratios are not used to design a level of torque; they are
used to create a saw with the optimum blade speed (blade Shaft RPM) for you.
The major factors are:
·
·
diameter of blade(s) you commonly use, and
cutting conditions you work under
The 4 gear ratios we have designed into the SP-6457 TD 4-speed Blade Shaft are:
1st Gear
2nd Gear
3rd Gear
4th Gear
1.00 : 1
1.34 : 1
1.70 : 1
2.02 : 1
In addition to the four” fixed” ratios of the Blade Shaft gears, we can also tailor
the Blade Shaft RPM (blade speed) by adjusting the “primary” ratio between the
engine and the Blade Shaft. By selecting a Blade Shaft sheave and Engine sheave,
a multitude of additional ratios (and Blade Shaft speeds) are possible. The
following Sheave sets are available as standard kits:

Drive System
This saw has a cable-controlled Hydro-Gear hydrostatic powered transaxle with
infinite F-N-R speed adjustment via a joystick controller. The saw is designed
with locked axle drive, and can travel at speeds up to 300 feet per minute.
Drive System Controls
The panel-mounted joystick controls FORWARD-NEUTRAL-REVERSE
(F-N-R) and infinitely variable speeds in both directions. To increase forward
speed, slowly move the joystick FORWARD. Pulling the joystick backward
decreases saw speed, and when the joystick passes NEUTRAL the saw moves
into REVERSE. Reverse speed is also controlled by the position of the joystick.
The Drive Disengage handle, when pulled, puts the saw in “free wheeling”
mode. This is not a “true” Neutral, but does provide a by-pass in the
pump/ motor group which allows the saw to be readily moved. Some rolling
resistance will be encountered.

4-Speed Blade Shaft
The exclusive 4-speed Blade Shaft allows optimum performance with a variety of
different blade sizes under a wide range of conditions.
Fig. 20 — The 4-Speed Blade Shaft
The 4-speed design fully encloses the transmission, bearings and Blade Shaft,
and features an oil bath lubrication (no grease fittings). Oil is cooled, filtered and
circulated, and the assembly utilizes a remote, protected fill and vent. Gear
changes are made with rack & pinion shifting. Positive shift lock prevents the
multi-speed Blade Shaft from jumping out of gear. A Blade Shaft tachometer
assists in gear selection.
The 4 gear ratios are:
1st Gear
2nd Gear
3rd Gear
4th Gear
1.00 : 1
1.34 : 1
1.70 : 1
2.02 : 1
The 1: 1 ratio is for the smallest diameter blade. The middle two ratios are for
intermediate sized blades and the 2.02 : 1 ratio is for the largest blade. Blade
range is from 16” to 48”.
discussion of the 4-speed Blade Shaft, gears, and sheave ratios.
To calculate Blade Shaft speed, assuming a 1:1 ratio between engine and blade
shaft input, divide engine speed by the selected ratio. For example, for the 3rd
gear Blade Shaft RPM: 2500 Engine RPM ÷ 1.7 = 1470 Blade Shaft RPM in 3rd gear.
The gear pattern is marked on the casting around the shift lever.

Blade Collar Removal/Installation
Correct removal or installation of the Inner Blade Collar or Flange requires the
Collar Puller (option Part Number 18503) shown in Figure 31.
Follow instructions closely to prevent injury from flying Blade Collars!
Because of the tapered fit between Blade Collar and Blade Shaft,
5-10 tons of force is needed to release the inner collar. Parts and
tools can become dangerous projectiles if instructions are not
followed properly.
WARNING
Fig. 31 — Using the Collar Puller
Removing the Inner Blade Collar
With the Outer Blade Collar in place, and the Blade Mounting Bolt loosened
approximately ¼”:
1. While the three perimeter bolts hold the two Puller Plates together, slide
the Horseshoe Plate of the Collar Puller behind the (Shaft) side of the
Inner Collar as shown above.
2. Tighten the center Puller bolt to remove the Inner Collar from the Blade
Shaft.
·
Having the Outer Collar in place prevents the Puller and Inner Collar from flying
off when the taper breaks loose, and causing injury!
·
If the Inner Collar does not readily come free from the tapered Blade
Shaft, lightly tap on the central Puller bolt. This should cause the collar to
break free from the shaft.

Raise/Lower Troubleshooting
If your new saw begins lowering all by itself when you release the Raise button,
the problem may be caused by debris in the hydraulic line which is blocking the
Lower valve in the open position.

Joystick Tension Adjustment
The speed control joystick uses friction adjustment to provide the preferred
“feel”:
1. Using a ¼” Allen wrench and 9/ 16” wrench, loosen both pivot bolts until
they can be turned by hand. Pivot #1 only requires a 9/ 16” wrench, as the
Allen nut side is welded in place.
2. Tighten pivot #1 until the handle is close to the desired “feel”.
3. Tighten pivot #2 until it just starts to increase the force required to move the
handle.

2. Collect and dispose of the used oil in an environmentally friendly manner.
3. Remove the used oil filter. See Fig. 44.
4. Once drained, reinstall the drain plugs.
5. Pre-fill and install a new oil filter.
To prevent hydraulic pump damage, pre-fill the filter with oil prior to
installing it.
CAUTION

To fill the hydraulic system:
1. Fully lower the saw.
2. Do not level the saw frame. The 4-Speed Blade Shaft is mounted at a 78° angle
to the saw frame. Adjust the level of the saw so that the face of the Blade Shaft
housing is at right angles to the ground.

Sight Glass
Fig. 46 — Filling the Hydraulic System
If the saw is not leveled correctly, the 4-Speed Blade Shaft could be
damaged by operating with too little, or too much, oil.
CAUTION
3. Add oil to the fill port on top of the 4-Speed Blade Shaft Housing.
4. Start the engine, and run it for a couple minutes to spread the oil throughout
the system
·
·
Add more oil as required.
Repeat steps 3 & 4 as necessary.
5. When the 4-Speed Blade Shaft is full, and positioned at 90° to the ground, the
oil should show between the center and the top of the sight glass on the front of the
main housing.
6. Inspect for leaks after service.
If the Blade Shaft is drained completely, it will require approximately
1 gallon to refill. If the transaxle is drained as well, it will require
approximately one additional gallon.

Bleeding the Depth Stop Cylinder
After changing the hydraulic system oil, or after disturbing the Depth Stop
Cylinder plumbing, air may become trapped in the system and cause the Depth
Stop Cylinder to work improperly. To remedy the situation, the Depth Stop
Cylinder must be bled to remove trapped air. This procedure requires the use of
the Depth Stop Block tool (P/ N 584042)..
1. Open the Depth Stop Valve.
2. Fully raise the saw.
3. Place the Depth Stop Block between the Depth Stop Plate and the Front
Axle.
4. Fully lower the saw.
·
Verify that the Depth Stop Cylinder has fully collapsed.
5. With the Depth Stop Valve still open, and the engine running:
·
·
At the rear of the cylinder use a 1/ 8” diameter hose on the bleeder nipple.
Use the length of hose to direct the flow of oil into a suitable receptacle.
Open the bleeder valve at the rear of the cylinder and allow the oil to flow
until no air is detected in the fluid. Close the bleeder valve.
Tighten the hose connection.
·
·
Dispose of the waste oil in an environmentally-friendly manner.
6. Remove the Depth Stop Block and test the operation of the Depth Stop.
7. Re-fill the Reservoir Fill bottle at the rear of the Fuel Tank.

Drive Wheel Alignment
Below is the technique recommended for aligning the wheels. Distance X is the
same on both sides; the Front Wheel and Blade shaft axles must be at right angles
to the frame edge. Distance A is 3/ 16” (.187”) longer on the right side, so that the
saw steers slightly left. Users may wish to alter the alignment to fit a particular
application.

Distance = A + .187”

The drive wheels are aligned by adjusting the entire rear drive assembly:
1. Loosen the Transaxle Attachment Bolts just enough to move the Transaxle
— do not completely loosen the bolts.
2. Loosen and tighten the Alignment Jackscrew nuts to move the Transaxle
— and thus the wheels — in the appropriate direction to achieve the
desired alignment distance (see Fig.46).
3. Lock down the Transaxle Attachment Bolts when the appropriate
alignment distance is set.
