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. r Confirm the rear and side access panels (5) & (6) and engine protector are in [...]

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 gasoline engine of the SP-6065 runs at 2800 RPM (full load). If 2800 RPM was a desirable Blade Shaft speed for the average conditions in which you wor[...]

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 We can also tailor the Blade Shaft RPM (blade speed) by adjusting the “primary[...]

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 12” diam. RPM 14” diam. RPM 16” diam. RPM 18” diam. RPM 20” diam. RPM 24” diam. RPM 26[...]

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. Verify that the unused Blade Collar (2) is secured to the Blade Shaft, by tightening the mounting bolt (3). Fig. 9 — The Collar Guard, Installed Collar Guard Collar Mounting Bolt[...]

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. 1. Connect th[...]

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 infinit[...]

38 Transaxle The Hydro-Gear hydrostatic-powered transaxle has no chains, sprockets or open gears to service. There is a simple cable control. The remote filter promotes long life and easy maintenance. Fig. 19 — The Transaxle Drain Plug[...]

39 Night Light The night light can be used on either side of the saw, and can be extended and rotated for best illumination of the cutting area. Aim the light , then lock it in position by tightening the lock knobs. The light can be removed for storage by loosening the lock knobs, disconnecting the light cord and sliding the light bar out of the sa[...]

40 Lift Point The convenient single point for lifting the saw with a hoist is located just in front of the console, between it and the engine.

Tighten the Engine Mount Lock Bolt. 5. Turn the Single Point Tension Bolt until the head of the bolt no longer touches the frame. Tighten the jam nut to prevent the bolt from [...]

45 Rotary Belt Tensioner The Rotary Belt Tensioner system uses a 3/4”-headed bolt and a 15/16” or 1” nut to set belt tension by positioning an arm between the Tensioner Pulley and the Tensioner Base. Ridges on the Base mark the amount of tension. 1. Loosen the Bolt Head. 2. Rotate the Tensioner Nut clockwise until the desired belt tension is [...]

46 Blade Shaft Maintenance The fully enclosed Blade Shaft eliminates most maintenance. However, should the Blade Shaft need service or repair, contact Multiquip for details. Fig. 28 — Blade Shaft Blade Shaft Replacement To assure correct Blade Shaft/Wheel alignment it is recommended that this operation be performed by a Multiquip Authorized Servi[...]

47 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.

Loosen the Rotary Tensioner and remove the Transaxle Belt. 3. Loosen the two Engine Mount Lock Bolts and the Single Point Belt Tension Bolt. Fig. 37 — Engine Mount Lock Bolts Single Po[...]

56 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. 4 5 3 2 1 Fig. 39 — Raise-Lower System Raise/L[...]

57 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[...]

58 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. ♦ Level the saw frame prior to service to get an accurate reading. ♦[...]

59 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. 43 — Hydraulic System Drains 2. Collect and dispose of the used oil in an environmentally friendly manner. 3. Remove the used oil filter. See Fig. 42. 4. Once drain[...]

60 To fill the hydraulic system with oil: 1. Add oil to the system reservoir. • The reservoir will need filling several times. 2. Run the engine for a couple minutes to cycle oil throughout the system. • Add more oil as required. 3. Repeat as necessary. Tips • It takes 3-4 quarts to fill the hydraulic system when new, and somewhat less when c[...]

61 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[...]

62 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[...]

63 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[...]
