4 BEFORE OPERA TING 1. Know the operating controls and how to stop quickly. 2. Do not allow children to operate the machine. Do not allow adults to operate the machine without proper instruction. 3. Remove all debris or other objects that might be picked up and thrown by the cutter blades.
5 13. Do not pass or stand on the grass discharge side of any mower with the engine running. Stop the cutter blades when another person approaches. Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm.
6 9. Always store gasoline in a safety-approved, red container. 10. Be careful when servicing the battery as it con- tains acid, which is corrosive and could cause burns to skin and clothing. 11. Batteries release explosive gases when being charged or discharged.
7 -NOTE- When the PTO is engaged or (possibly) disen- gaged, a squealing sound from the underside of the machine is normal. It is caused by the electric clutch plates meshing as the cutter blades come up to speed. For best equipment life, engage the clutch with the engine at 3/4 throttle, not under full load.
8 ADJUSTMENTS PARKING BRAKE Minor brake adjustments can be made by loosening the top nut on both brake cables (see Figure 4). Back the nuts off approximately 1/4". While pulling one cable downward, tighten the bottom nut on the cable until it touches the bottom of the brake cable mount.
9 Use of Tension Gauge sgb007 5. Check the adjustment of the right foot control pedal for full forward speed. The pedal should rest on the foot plate when the pump is stroked in the full forward position. To make an adjustment, discon- nect the ball joint from the pedal arm and loosen the jam nut (See Figure 6).
10 Adjust the tension by tightening or loosening the nut on the J-bolt. 4. Replace the belt covers. BEL T ALIGNMENT Belt alignment is important for proper performance of your Scag mower. If you experience frequent belt wear or breakage, see your authorized Scag Service Dealer for belt adjustment.
11 There are three positions for mounting the cutter deck (See Figure 11). For cutting in the lowest position, mount the cutter deck in the top hole (A). For cutting in the highest position, mount the deck in the lowest hole (C). Setting the cutter deck height will be determined by the type of cutting conditions.
12 A . 3" Position - baffle is installed using the top set of holes on the front baffle welded inside the cutter deck. (See Figure 15). The Advantage cutter deck will deliver the best quality-of-cut in very tall, wiry , tough to cut grass.
