19 O PERATION 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.
20 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).
21 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.
22 Blade RPM vs. Surface Feet Per Minute (SFPM) When choosing a blade for your cutting conditions, follow the blade manufacturer’s recommendations. Match the blade speed (Blade Shaft RPM) to the recommended blade Surface Feet Per Minute (SFPM). SFPM 16” diam.
23 Installing the Blade The blade can be mounted on either side of the saw to accommodate different cutting jobs. 1. Raise the saw so that the blade will clear the ground when installed. 2. Verify that blade collars are clean and undamaged. 3. Insert the bushing and mounting bolt through the outer collar and blade.
24 Stacking Blades for Wide Cuts WARNING NEVER attempt to stack blades beyond the capacity of the Kits described here. NEVER operate the saw without blade guards in place. Combining (stacking) blades together to make wide cuts requires an optional Bushing Extension Kit.
25 Installing and Removing the Blade Guard Blade Guards are “ambidextrous” – that is, they can be installed on either side of the saw. Installing the Blade Guard 1. Slide the Blade Guard Mounting Clip onto the Guard Mounting Tab on the frame. 2.
26 Blade Guard Water Supply Verify that the water hose on the saw is connected to the Blade Guard and that the water pipes are pointed into both Blade Collars. CAUTION Make sure that the 90º outlets of the water tubes point toward the lower portion of the blade collars, aimed at the delivery ports, for proper water delivery to the blade.
27 Installing the Collar Guard The Collar Guard protects unused Blade Collars. 1. Slide the Collar Guard (1) onto the Guard Mounting Tab on the frame. 2. Verify that the unused Blade Collar (2) is secured to the Blade Shaft, by tightening the mounting bolt (3).
28 Water Supply and Control CAUTION § To prevent damage to the impeller of a belt driven water pump , do not run the engine with the water pump switch on, unless the water supply is connected and water is flowing. § When storing the saw during freezing weather, blow out the water lines to prevent damage to the water delivery system.

51 5. Loosen the Mounting Bolt and remove the Outer Collar and Bushing. 6. Inspect the Inner Collar to ensure the proper seating of the tapered fit. • The Inner Collar should be seated between .030” and 0.0” (flush) to the end of the Blade Shaft.
52 Circuit Breakers Three thermal circuit breakers are located inside the top of the Console. Fig. 34 — Circuit Breaker location Under normal circumstances circuit breakers do not require service; they are automatically re-set when an overload condition is corrected.
53 Lubrication This saw has five grease fittings on the front axle assembly. • Front axle pivot bearings (F1 & F3) • Hydraulic lift cylinder ends (F2, and far end of cylinder) • Depth Stop P.
54 Engine The Model SP-6457 TD features a Turbocharged 57 HP Deutz diesel engine. See the engine manual for service details and oil recommendations. • Check air filters daily, replace as required. Do Not clean air filters. • Check engine oil level daily.
55 PTO Drive Maintenance Disassembly of the PTO Drive and replacement of the PTO Drive Sheave/Bearing Assembly requires the PTO Bearing Puller (P/N 18610). The Sheave/Bearing Assembly is not serviceable and must be replaced as a complete unit. 1. Remove the Drive Belt (see Replacing the Blade Shaft Drive Belt).
56 Fig. 38 — PTO Drive Sheave/Bearing Assembly Re-Assembling the PTO Drive 1. Clean and inspect all parts. 2. Use a press to push the new Bearing/Sheave assembly onto the Bearing Support (9) until the bearings contact the shoulder of the Support. 3.
57 Replacing the Battery This saw uses a Group 75, 12-Volt, 1000 cold cranking amp battery. To replace the battery: 1. Remove Engine Guard and Upper Belt Guard. 2. Loosen the Rotary Tensioner and remove the Transaxle Belt. 3. Loosen the two Engine Mount Lock Bolts and the Single Point Belt Tension Bolt.
58 Raise-Lower System This saw uses a 12-volt hydraulic pump and hydraulic cylinder to power the raise-lower system. • Level frame prior to service to get an accurate reading. • Check oil level daily. • Fill the reservoir half to two-thirds full when cold • Use 5W-30 premium grade engine oil.
59 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.
60 Hydraulic System Maintenance The hydraulic system consists of: § Blade Shaft § Hydraulic Pump § Transaxle § Hydraulic Manifold § Depth Stop Cylinder & Valve § Hydraulic Filter § Lift Cylinder § Oil Fill/ System Vent Routine Maintenance • Check oil level daily.
61 Draining & Filling the Hydraulic System To drain the hydraulic system: 1. Remove the drain plug from the bottom of the Blade Shaft housing and the bottom of the Transaxle. Fig. 45 — Hydraulic System Drains 2. Collect and dispose of the used oil in an environmentally friendly manner.
62 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.
63 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.
64 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.
65 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.
