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). If 2800 RPM was a desirable Blade Shaft speed for the average conditions in which you wo[...]

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. 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: [...]

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. RPM 18” diam. RPM 20” diam. RPM 24” diam. RPM 26” diam. RPM 30” diam. RPM 36[...]

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. • Align collar pin through the [...]

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. • Kit #18501 allows blade stacking from .375” to .75” thickness. • 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. Connect the water delivery hose to the Blade Guard. • Ensure that the water pipes are pointed to[...]

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. Fig. 8 ?[...]

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.

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. Fig. 45 — Adjusting the level of the Blade Shaft Fig. 46 — Filling the Hydraulic Sy[...]

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. This procedure requires the use of the Dept[...]

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. Users may wish to alter the alignment to fit a pa[...]

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. 2. Loosen and tighten the Alignment Jackscrew nuts to move the Transaxle — and thus the wheels — in the appropriate direction to achieve the desired align[...]
