BEFORE OPERATION CONSIDERATIONS (CONT'D)
4.Always wear appropriate clothing, loose fitting clothing, long hair or jewelry could get tangled in moving parts. Do not operate the machine wearing shorts; always wear adequate protective clothing including long pants. Wearing safety glasses, safety shoes and a helmet is advisable and is required by some local ordinances and insurance regulations.
5.Operator hearing protection is recommended, particularly for continuous operation of the mower. Wear suitable hearing protection. Prolonged exposure to loud noise can cause hearing impairment or hearing loss.
6.Keep the machine and attachments in good operating condition. Keep all shields and safety devices in place. If a shield, safety device or decal is defective or damaged, repair or replace it before operating the machine.
WARNING:
This machine is equipped with an interlock system intended to protect the operator and others from injury. This is accomplished by preventing the engine from starting unless the deck drive is disengaged, the transmission is in neutral, and the neutral latches are in the neutral position. The system shuts off the engine if the operator releases the operator presence levers with the deck drive engaged and/or the transmission not in neutral. Never operate equipment with the interlock system disconnected or malfunctioning.
7.Fill the fuel tank with clean, fresh gasoline, with a minimum octane rating of 87. To avoid personal injury or property damage, use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive.
A. Extinguish all cigarettes, cigars, pipes and other sources of ignition.
B. Use only an approved gasoline container.
C.Never remove the gas cap or add fuel with the engine running. Allow the engine to cool before fueling.
D.Never fuel the machine indoors or in an enclosed trailer.
E.Never store the machine or fuel container where there is an open flame, spark or pilot light such as on a water heater or other appliances.
F.Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground away from your vehicle before filling.
G.Remove the machine from the truck or trailer and fuel on the ground. If this is not possible, then refuel the machine with a portable container, rather than from a gasoline dispenser nozzle.
H.Keep the nozzle in contact with the rim of fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.
I.If fuel is spilled on clothing, change clothing immediately
J.Replace gas cap and tighten securely.

2.Adjust the steering brake rods so that the brakes do not apply until the steering levers are pulled tight to the handles. When the steering levers are locked in the neutral position the machine should move freely.
CUTTER DECK ADJUSTMENTS
Due to the many cutting conditions that exist, it is difficult to suggest a cutter deck setting that will work for every lawn. There are two adjustments that can be made on these decks, pitch and height.
PITCH is the angle of the blades (comparing front to rear). A 1/4" downward pitch (front of deck down) is recommended for best cutting performance.
HEIGHT is the nominal distance the blade is off of the ground. This measurement is made with the blades pointed side to side and distance is measured between cutting tip and ground. (Also see Blade Height Adjustment, next page).
Changes to the cutting height can be achieved by repositioning the cutter deck. (This adjustment will also effect the pitch of the deck). There are three available positions (See Figure 5).
LOW CUT (1 3/4" to 3")
MID RANGE (2 1/2" to 3 3/4")
HIGH CUT
(3 1/4" to 4 1/2")
SC405G-2

Figure 6. Caster Wheel Spacers
BLADE HEIGHT ADJUSTMENT
Adjusting the blade height can be done by moving any number of the five smaller 1/4" spacers on the blade mounting bolts to the top of the spindle shaft or below the spindle shaft.
-NOTE-
All blades should be positioned equally.
For best cut and discharge, a minimum of three spacers should be installed between the blade and the spindle (See Figure 7).
WARNING:
Blades have a sharp cutting edge. Wear proper eye protection and protective gloves or wrap blades with protective material when removing, sharpening and installing blades.

CUTTER BLADES
Do not sharpen beyond 1/3 of the width of the blade. (See Figure 8).
-NOTE-
Dress the blade with a file. Using a wheel grinder may burn the blade. Check the balance of the blade. If blades are out of balance, vibration and premature wear of spindle assembly can occur. See your authorized Scag dealer for blade balancing or special tools, if you choose to balance your own blades.

CUSTOM-CUT BAFFLE ADJUSTMENT
The Custom-Cut Baffle is designed to deliver optimum airflow and superior cutting performance in any type of grass. The Custom-Cut Baffle can be raised or lowered to precisely tailor the deck's performance for the type of grass being cut. The baffle can be set in three (3) different positions for optimum performance.
A.3" Position - baffle is installed using the top set of holes on the front baffle welded inside the cutter deck. (See Figure 10). The Advantage cutter deck will deliver the best quality-of-cut in very tall, wiry, tough to cut grass.
B.3-1/2" Position (factory setting) - baffle is installed using the middle set of holes on the front baffle welded inside the cutter deck. (See Figure 11). For general purpose cutting, place the Custom Cut Baffle in the 3-1/2" position. This gives the best mix of cutting performance in all types of grass.
C.4" Position - baffle is installed using the bottom set of holes on the front baffle welded inside the cutter deck. (See Figure 12). Placing the baffle in the 4" setting will enhance fall cutting (leaf pickup) and reduce cutter deck "blowout".
TO ADJUST THE CUSTOM-CUT BAFFLE HEIGHT:
1.Remove the hardware securing the Custom-Cut Baffle to the cutter deck (See Figure 9).
-NOTE-
Hardware location used in the illustrations are for reference only. Location of hardware may vary depending on the cutter deck size.
2.Move the Custom-Cut Baffle to desired position. (See Figures 10 through 12 for position)
3.Reinstall the mounting hardware as shown. (See Figures 10 though 12). Torque hardware to 39ft.lbs.
