WARNING
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.

§ NEVER operate this saw without proper protective clothing;
shatterproof glasses, steel-toed boots, respiration mask, and any
other protective devices required by the job.
11
§ Before operating the saw, make sure all protective guards are
securely in place. Multiquip saws are supplied with a blade guard,
collar guard and belt guard.
§ Whenever necessary, replace operation and safety decals if they
become difficult to read.
§ Verify the engine start switch is set to the OFF position before
installing a blade.
§ Make sure the operator knows how to turn the engine OFF in case
of an emergency.
§ Do not go near rotating parts (blades, belts, pulleys or wheels)
while engine is running.
§ Catalytic muffler and exhaust gases are extremely hot. Stay clear
of muffler and exhaust gases. Allow these parts to cool before
servicing the saw.
§ Stay clear of the saw while it is being hoisted.
§ Anytime the saw is lifted onto its nose, or tilted fully back, for

§ Make sure the operating area is clear before starting the engine.
§ Maintain this equipment in a safe operating condition at all times.
§ Keep the saw clean. It will work better and last longer.
§ Use proper blades and follow the blade manufacturer’s
recommendations. Match blade rpm (Blade Shaft rpm) to
recommended blade surface feet per minute (SFPM).
§ Tighten the 5/8” blade-mounting bolt to 100-125 foot-lbs. torque.
§ Turn engine OFF prior to fueling the saw.
§ Start engine with the joystick in NEUTRAL to prevent unexpected
saw movement.
CAUTION
§ Do not leave saw unattended while engine is running.
§ Do not start engine on a sloping surface to prevent unexpected
loss of control.
§ Do not park or leave saw unattended on a slope - the saw can roll
when the engine is OFF. Block the unit when leaving.
§ If the saw must be parked on a slope, turn it across the angle of
the slope, to prevent accidental downhill movement.
§ Always store equipment properly when not being used. Equipment
should be stored in a clean, dry location out of the reach of
children. When storing the saw in freezing weather, blow out
water lines to prevent damage to components in the water
delivery system.
§ Prior to service, level the frame surface.
§ Do not over tighten the Blade Shaft drive belt.
§ Turn on water flow prior to starting the engine, to prevent
damage to the impeller of a belt-driven water pump.
13
§ Don’t pollute! Waste oils and other chemicals must be disposed
of in a manner consistent with local and state environmental
protection regulations.
BLADE SAFETY
WARNING
§ ALWAYS inspect diamond blades before each use. The blade
should exhibit no cracks, dings, or flaws in the steel centered core
and/or rim. Center (arbor) hole must be undamaged and true.
§ Examine blade flanges for damage, excessive wear and
cleanliness before mounting blade. Blade should fit snugly on the
shaft and against the inside/outside of the saw.
§ Only cut the material that is specified by the blade. Read the
specifications of the blade to ensure the proper tool has been
matched to the material being cut.
§ ALWAYS keep blade guards in place. Exposure of the blade must
not exceed 180 degrees.
§ Ensure that the blade does not come into contact with the ground
or surface during transportation. DO NOT drop the blade on the
ground or surface.
§ The engine governor is designed to permit maximum engine
speed in a no-load condition. Speeds that exceed this limit may
cause the blade to exceed the maximum safe allowable speed.
§ Ensure that the blade is mounted for proper operating direction.
14
SAW TRANSPORTATION SAFETY
CAUTION
§ Use appropriate lifting equipment to ensure the safe movement of
the saw.
§ DO NOT use the handle bars and/or front pointer as lifting points.
§ NEVER attempt to tow the untrailered saw behind a vehicle.
§ NEVER transport the saw with the blade mounted.

OPERATION
Before Starting
Before starting the saw, carefully follow the checklist below:
r Securely install the Belt Guard (2).
r Fully slide on the Collar Guard (3).
r Verify that proper-sized Blade Guard (4) is fully installed on the Blade
Guard mounting tab.
r Confirm the rear and side access panels (5) (6)& (7) and engine
protector are in place.
r Wear eye and hearing protection and protective clothing.
r Adjust handle bars (1) for best operator control.
r If a belt driven water pump is installed, do not run the engine with the
water pump switch on, unless the water supply is connected and
water is flowing.

Fig. 3 — Guards & Panels
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
Fig. 4 — Blade Shaft Ratios
Engine
Blade Shaft
Engine
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
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 1.00 : 1
2nd Gear 1.34 : 1
3rd Gear 1.70 : 1
4th Gear 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:

Starting and Stopping The Engine
§ Do not leave the saw unattended while the engine is running.
§ Do not start, park, or leave the saw unattended on a slope.
§ If the saw has an optional water pump, do not run the saw dry
with the water pump switch ON — otherwise the pump impellers
will be damaged.
CAUTION
1. Move the speed control joystick to NEUTRAL position.
2. Set the throttle to IDLE.
3. Ensure that water lines are attached and water is flowing to the saw.
4. Momentarily turn the ignition switch to the START position.
• Allow the engine to warm up for several minutes.
5. Set the throttle to the recommended engine RPM to match the recommended
blade speed of the attached blade.
6. Lower the blade to the cut depth.
7. Move the joystick FORWARD to advance the cut.
8. To stop the engine, turn the ignition switch to the OFF position.
§ Do not stop the engine abruptly when hot! Reduce the throttle to
idle and allow the engine to run one or two minutes before turning
the ignition switch off. This allows the engine to cool down, and
prevents damage to the Turbo unit.
Fig. 14 — ON/OFF Switch Location
§ Make sure the operator knows how to turn the engine off in case
of an emergency.
WARNING
§ Do not go near rotating parts (blade, belts, pulleys, or wheels)
while the saw is running.
Restarting After Running Out of Fuel
The 1011 series Deutz engines do not require bleeding the fuel system if you run
out of fuel. To restart the engine, simply re-fill the fuel tank, and crank the
engine normally (should be only 5-10 seconds) until it re-starts.

Drive System
Speed Control
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 1.00 : 1
2nd Gear 1.34 : 1
3rd Gear 1.70 : 1
4th Gear 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”.
See page 21 or visit our web site: www.multiquip.com for additional
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

Blade Collar Removal/Installation
WARNING
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.
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.
49
Installing the Inner Blade Collar
1. Ensure that the tapered portion of the Blade Shaft, and the Inner Blade Collar
are perfectly clean and free of burrs or indentations. Clean and repair as
necessary
2. Ensure that the Drive Key is in place.
3. Slide the Inner Collar onto the tapered portion of the Blade Shaft
• DO NOT use any lubricant! Lubricant prevents the tapered surfaces of the
Collar and Shaft from mating properly.
4. Install the Outer Blade Collar, Collar Bushing, and Mounting Bolt.
• Tighten with a ½” impact wrench to seat the tapered surfaces of the Inner
Collar and Blade Shaft.

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.

The drive wheels are aligned by adjusting the entire rear drive assembly:
Adjustment Side
Alignment
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.
