6
Page 11
Section 2
This mower has been designed for good traction and stability under normal mowing conditions. However, caution must be used when traveling on slopes, especially when the grass is wet. Do not mow on wet grass. Wet grass reduces traction and steering control.
Any or all parts of the Roll Over Protection System MUST NOT be removed. Failure to adhere to this guideline could result in injury or death.
The potential exposure of this seat belt to severe enviromental conditions make it crucial to inspect the seat belt system regularly .
It is recommended that the seat belt be inspected on a daily basis for signs of damage. Any seat belt system that shows cuts, fraying, extreme or unusual wear, significant discoloration due to UV exposure, dirt or stiffness, abrasion to the seat belt webbing, or damage to the buckle, latch plate, hardware or any other obvious problem should be replaced immediately .
INSPECT BUCKLE & LATCH
INSPECT WEBBING
Figure 2-1 Seat Belt Inspection
WARNING:
Reduce speed when turning, operating on slopes, slick or wet surfaces. Allow extra distance to stop.
Stay off of slopes too steep for safe operation. To check a slope, attemp to back up it (with the cutter deck down). If the machine can not back up the slope without the wheels slipping, do not operate the machine on this slope.
WARNING:
Failure to properly inspect and maintain the seat belt can cause serious injury or loss of life.
1. Check the full length of the seat belt webbing for cuts, wear, fraying, dirt and stif fness. See Figure 2-1.
2. Check the seat belt webbing in areas exposed to ultra violet rays from the sun or extreme dust or dirt. If the original color of the webbing in these areas is extremely faded and/or is packed with dirt, the physical strength of this webbing may have deteriorated. If this condition exists, replace the seat belt system.
3. Check the buckle and latch for proper operation and determine if the latch plate is exessively worn, deformed, or of the buckle is damaged or cracked. See Figure 2-1.
ALWAYS travel up or down the slope whenever possible. Never across the slope.
DO NOT mow near drop-offs, ditches or embankments. The machine could suddenly roll over if a wheel goes over the edge or if the edge caves in.
Operate the machine smoothly, no sudden turns, starts or stops on a slope.
NEVER tow on slopes. The weight of the towed equipment may cause loss of traction and loss of control.
DO NOT permit untrained personnel to operate the machine.

Section 4
4.3 INITIAL RUN-IN PROCEDURES (First Day of Use or Approximately 10 Hours)
1. Check all belts for proper alignment and wear at 2, 4 and 8 hours.
2. Change the engine oil and oil filter after the first 5 hours of operation. (See Section 7.4.)
3. Check hydraulic oil level in reservoir. (See Section
7.3.)
4. Check for loose hardware. Tighten as needed.
5. Check interlock system for proper operation. (See
Section 4.2.)
6. Check tire pressure. Adjust pressure if necessary.
(See Section 7.10)
4.4 STARTING THE ENGINE
CAUTION:
DO NOT USE STARTING FLUIDS. Use of starting fluids in the air intake system may be potentially explosive or cause a “runaway” engine condition that could result in engine damage and/or personal injury .
6. Move the engine throttle control to about half engine speed.
7. Turn the ignition key to the on position until the yellow indicator for the glow plugs goes out. Then turn the ignition key to the ST AR T position and release the key as soon as the engine starts. Do not hold the key in the ST ART position for more than 15 seconds at a time. Allow at least 60 seconds between each cranking attempt to prevent overheating of the starter motor. Prolonged cranking can damage the starter motor and shorten battery life.
8. Allow engine to warm before operating the mower.
4.5 GROUND TRAVEL AND STEERING
-IMPORTANT-
If you are not familiar with the operation of a machine with lever steering and/or hydrostatic transmissions, the steering and ground speed operations should be learned and practiced in an open area, away from buildings, fences, or obstructions. Practice until you are comfortable with the handling of the machine before attempting to mow. Learn the operation on flat ground before operating on slopes.
-IMPORTANT-
Start practicing with a slow engine speed and slow forward travel.
1. Before initial start or after running out of fuel, you must prime the fuel pump located on the right side of the engine. Pump the primer pump until it can no longer be depressed.
2. Be sure the fuel shutoff valve, located behind the operator's seat, is completely open. (See Section 7.5 Page 30)
3. Sit in the operator’s seat, fasten seat belt and place the steering control levers in the neutral position.
4. Engage the parking brake.
5. Place the PTO switch in the disengaged position.
Learn to feather the steering controls to obtain a smooth operating action.
Practice operating the mower until you are comfortable with the controls before proceeding to mow.
Forward T ravel
T o travel forward with the mower , disengage the parking brake and slowly push the steering control levers forward an equal distance. The further the steering control levers are pushed forward, the greater the forward speed will be. To increase the speed, push the steering control levers further forward and to decrease the speed, pull the steering control levers back.
14
Page 19
Section 4
T o stop the forward travel, pull the steering control levers back to the neutral position.
T o steer the mower left while traveling forward, pull the left steering lever back. The further the lever is pulled back, the quicker the mower will turn left.
T o steer the mower right while traveling forward, pull the right steering control lever back. The further the lever is pulled back, the quicker the mower will turn right.
-NOTE-
Smooth operation of the steering levers will produce smooth mower operation. While learning the operation of the steering controls, keep the travel speed low.
-IMPORTANT-
Do not travel forward over a curb. The mower will hang up on the curb. Raise the deck and travel backwards over the curb at a 45 degree angle. (see section 4.13 on Page 16 for cutter deck raising instructions)
Reverse Travel
-NOTE-
The mower may not travel straight in reverse. Slight adjustments may need to be made using the steering controls.
T o steer left while traveling in reverse, allow the left steering control lever to move forward. The further the control is allowed to move forward, the quicker the mower will turn left.
T o steer right while traveling in reverse, allow the right steering control lever to move forward. The further the control is allowed to move forward, the quicker the mower will turn right.
T o stop the reverse travel, allow the steering control levers to return to the neutral position. If the mower is to be parked, engage the parking brake.
4.6 ENGAGING THE DECK DRIVE (CUTTER BLADES)
1. Set the throttle at about 3/4 speed. Do not attempt to engage the deck drive at high speed as this shortens the electric clutch life — use only moderate engine speed when engaging the deck drive.
CAUTION:
Disengage power to the mower before backing up. Do not mow in reverse unless absolutely necessary and then only after observation of the entire area behind the mower .
CAUTION:
Before backing up, observe the rear for persons and obstructions. Clear the area before backing up. Possible injury or property damage could occur .
T o travel in reverse, pull both handles back. Keep the travel speed low while traveling in reverse.
2. Engage the deck drive by pulling out on the yellow switch, located on the instrument panel, (Figure 4-3) to the engage position.
PULL UP TO ENGAGE
PUSH DOWN TO DISENGAGE
STT99CES
Figure 4-3 Cutter Engage Switch
-NOTE-
A squealing noise may be heard when engaging or disengaging the deck drive. It is caused by the electric clutch plates meshing as the mower comes up to speed.
15
Page 20
Section 4
3. T o disengage the deck drive, push the switch in to the disengage position.
4. Always operate the engine at full throttle to properly maintain cutting speed. If the engine starts to lug down, reduce the forward speed and allow the engine to operate at maximum RPM.
5. To properly burnish the electric PTO clutch brake,
follow the following steps.
A. Start and run the engine at approximately 3/4 throttle.
B. Engage and disengage the PTO approximately 25 times, waiting for 10 seconds between each on/off cycle.
-NOTE-
Burnishing the electric clutch improves longevity and performance and should be done on every new machine and after a clutch replacement. The burnishing procedure should not be performed while cutting grass.
3. Keep tires properly inflated.
4.8 PARKING THE MOWER
1. Stop on level ground and place the steering control levers in the neutral position.
2. Disengage the cutter blades
3. Slow the engine to idle speed.
4. Engage the parking brake.
5. Turn the ignition key to the OFF position and remove the key.
4.9 AFTER OPERATION
1. Wash the entire mower after each use. Do not use high pressure spray or direct the spray onto electrical components.
4.7 HILLSIDE OPERATION
WARNING:
DO NOT operate on steep slopes. T o check a slope, attempt to back up it (with the cutter deck down). If the machine can back up the slope without the wheels slipping, reduce speed and use extreme caution. ALWAYS FOLLOW OSHA APPROVED OPERATION.
1. The mower has been designed for good traction and stability under normal mowing conditions. However, caution must be used when traveling on slopes, especially when the grass is wet. Wet grass reduces traction and steering control. The Roll Over Protection System is standard equipment for this machine. See section 2.5, page 6 of this manual for further details.
-IMPORTANT-
Do not wash a hot or running engine. Cold water will damage the engine. Use compressed air to clean the engine if it is hot.
2. Keep the entire mower clean to inhibit serious heat damage to the engine or hydraulic oil circuit.
3. Check the drive belts for proper alignment and any signs of wear. Correct and adjust if necessary.
T o a v oid injury fr om burns, allow the mower to cool before removing the fuel tank cap and refueling.
4. After the mower has cooled down, fill the fuel tank with fresh, clean fuel with a minimum cetane rating of 40 at the end of every day of operation.
2. T o prevent tipping or loss of control, start and stop smoothly , avoid unnecessary turns and travel at reduced speed.
5. Check the tire pressure. Adjust pressure if necessary.

WARNING
4.10 REMOVING CLOGGED MATERIAL
ROTATING BLADES
NEVER PUT Y OUR HANDS INTO THE DISCHARGE CHUTE FOR ANY REASON! Shut off the engine and remove the key and only then use a stick or similar object to remove material if clogging has occurred.
1. If the discharge chute becomes clogged, shut off the engine and remove the ignition key . Using a stick or similar item, dislodge the clogged material. Then resume normal mowing.
4.11 MOVING MOWER WITH ENGINE
STOPPED
T o “free-wheel” or move the mower around without the engine running, place the dump valve levers in the FREE­WHEEL position (Figure 4-2). Disengage the parking brake and move the mower by hand. The dump valve levers must be returned to the DRIVE position and torqued to 10ft/lbs to drive the mower.
3. Cut grass when it is dry and not too tall. Do not cut grass too short (cut off 1/3 or less of existing grass for best appearance). Mow frequently .
4. Keep mower and discharge chute clean.
5. When mowing wet or tall grass, mow the grass twice. Raise the mower to the highest setting for the first pass and then make a second pass to the desired height.
6. Use a slow travel speed for trimming purposes.
7. Operate the engine at full throttle for best cutting. Mowing with a lower RPM causes the mower to tear the grass. The engine is designed to be operated at full speed.
8. Use the alternate stripe pattern for best lawn appearance. Vary the direction of the stripe each time the grass is mowed to avoid wear patterns in the grass.
DUMP VALVE
CONTROL
4.12 RECOMMENDATIONS FOR MOWING
1. Do not mow with dull blades. A dull blade will tear grass, resulting in poor lawn appearance and reduced mowing power.
2. The discharge chute must not be removed and must be kept in the lowest position to deflect grass clippings and thrown objects downward. Direct the side discharge away from sidewalks or streets to minimize cleanup of clippings. When mowing close to obstacles, direct the discharge away from the obstacles to reduce the chance of property damage by thrown objects.
WARNING
DO NOT OPERATE WITHOUT DISCHARGE CHUTE, MULCHING KIT, OR ENTIRE GRASS CATCHER INSTALLED

6.6 CUTTER DECK ADJUSTMENTS
Cutter deck level, pitch and height are set at the factory. However, if these adjustments should ever need to be made, the following procedures will aid in obtaining the proper cutter deck adjustment.
-NOTE-
Before proceeding with the cutter deck adjustments, be sure that all tires are properly inflated.
Cutter Deck Level
The cutter deck should be level from side-to-side for proper cutting performance. To check for level, be sure that the mower is on a flat, level surface, the tires are properly inflated and the cutter deck is set at the most common cutting height that you will use. On the RH side of the machine, check the distance from the bottom of the cutter deck to the floor. Next check the distance from the bottom of the cutter deck to the floor on the LH side of the machine. Both measurements should be the same. If the two measurements are different, the cutter deck level must be adjusted as follows:
1. On the front LH side of the cutter deck locate the
cutter deck adjusting bolt. (See Figure 6-5)
JAM NUT ADJUST HERE
3. Tighten the elastic stop nut to secure the cutter deck in the proper position.
Cutter Deck Pitch
The pitch of the cutter deck should be equal between the front and rear of the cutter deck for proper cutting performance. To check for proper deck pitch, be sure that the mower is on a flat, level surface and the tires are properly inflated. Use the following procedures, however, measure from the top of the cutter deck rather than the bottom edge. Lay a straight edged object on the top of the Advantage cutter deck, protruding towards the front of the machine, when measuring the front height.
Check the distance from the top of the cutter deck to the floor at the rear RH side of the cutter deck directly behind the cutter deck hanging chains. Next check the distance from the top of the cutter deck to the floor at the front RH side of the cutter deck directly in front of the cutter deck hanging chains. The measurement at the front of the cutter deck should be equal to the measurement at the rear of the deck. Make these measurements at the LH side of the cutter deck also. If the measurement at the front of the deck is not equal to the rear, the cutter deck pitch must be adjusted as follows:
1. Loosen the jam nuts on both adjusting rods. (See Figure 6-5)
2. Using a wrench on the spring compression nut (See Figure 6-5) turn the adjusting rods until the 1/4" forward pitch is obtained on both the RH and the LH side of the cutter deck. Tighten both jam nuts.
390S0174-1
Figure 6-5. Cutter Deck Adjustment
2. Loosen the elastic stop nut and move the bolt up or down in the slot to adjust the cutter deck until the distance from the bottom of the cutter deck to the floor is the same as the measurement on the RH side of the machine.
-NOTE-
To prevent the cutter deck from teetering, all four cutter deck hanging chains must have tension on them. If all four chains do not have tension on them and the deck teeters, you must readjust the cutter deck as outlined in the procedures above.

7.3 HYDRAULIC SYSTEM
A. Checking Hydraulic Oil Level
The hydraulic oil level should be checked after the first 10 hours of operation. Thereafter, check the oil after every 200 hours of machine operation or monthly , whichever occurs first.
-IMPORTANT-
If the oil level is consistently low, check for leaks and correct immediately.
1. Wipe dirt and contaminants from around the reservoir cap. Remove the cap from the hydraulic oil reservoir.
2. Visually check the level of hydraulic oil. Hydraulic oil must be at least 3" inches from top of the filler neck. If the level cannot be determined visually , use a clean tape measure to check the level. If the fluid is low , add 20W50 motor oil. DO NOT overfill; (overfilling the oil reservoir may cause oil seepage around the cap area).
B. Changing Hydraulic Oil
The hydraulic oil should be changed after every 500 hours or annually, whichever occurs first. The oil should also be changed if the color of the fluid has become black or milky. A black color and/or a rancid odor usually indicates possible overheating of the oil, and a milky
color usually indicates water in the hydraulic oil.
-NOTE-
The hydraulic oil should be changed if you notice the presence of water or a rancid
odor to the hydraulic oil.
1. Park the mower on a level surface and stop the engine.
2. Place a suitable container under the hydraulic oil reservoir. Remove the fill cap from the reservoir. Remove the drain plug from the bottom of the reservoir. (See Figure 7-2). Allow the fluid to drain into the container and properly discard it.
3. Clean the fill cap and install it onto the reservoir.

33
Page 38
WARNING:
Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to cause cancer and reproductive harm. Wash hands after handling.
WARNING:
Electric storage battery fluid contains sulfuric acid which is POISON and can cause SEVERE CHEMICAL BURNS. Avoid contact of fluid with eyes, skin, or clothing. Use proper protective gear when handling batteries. DO NOT tip any battery beyond 45° angle in any direction. If fluid contact does occur, follow first aid suggestions below.
BATTERY ELECTROLYTE FIRST AID
EXTERNAL CONTACT — Flush with water.
Section 7
B. Charging the Battery
Refer to the battery charger’s manual for specific instructions.
Under normal conditions the engine’s alternator will have no problem keeping a charge on the battery. If the battery has been completely discharged for a long period of time, the alternator may not be able to recharge the battery, and a battery charger will be required.
DO NOT charge a frozen battery. It may explode and cause injury. Let the battery warm before attaching a charger.
Whenever possible, remove the battery from the mower before charging and make sure the electrolyte covers the plates in all cells.
WARNING:
BATTERIES PRODUCE EXPLOSIVE GASES. Charge the battery in a well ventilated space so gases produced while charging can dissipate.
EYES — Flush with water for at least 15 minutes and get medical attention immediately.
INTERNAL — Drink large quantities of water. Follow with Milk Of Magnesia, beaten egg, or vegetable oil. Get medical attention immediately. In case of internal contact, DO NOT give fluids that would induce vomiting.
Charging rates between 3 and 50 amperes are satisfactory if excessive gassing or spewing of electrolyte does not occur or the battery does not feel excessively hot (over 125°F). If spewing or gassing occurs or the temperature exceeds 125°F, the charging rate must be reduced or temporarily stopped to permit cooling.
C. Jump Starting
1. The booster battery must be a 12 volt type. If a vehicle is used for jump starting, it must have a negative ground system.
2. When connecting the jumper cables, connect the positive cable to the positive battery post, then connect the negative cable to the negative battery post.

LIMITED WARRANTY - COMMERCIAL EQUIPMENT
Any part of the Scag commercial mower manufactured by Scag Power Equipment and found, in the reasonable judgment of Scag, to be defective in materials or workmanship, will be repaired or replaced by an Authorized Scag Service Dealer without charge for parts and labor . This warranty is limited to the original purchaser and is not transferable. Proof of purchase will be required by the dealer to substantiate any warranty claims. All warranty work must be performed by an Authorized Scag Service Dealer.

(Parts and labor 1st year; Parts only 2nd and 3rd year) The repair or replacement of the cutter deck will be at the option of Scag Power Equipment. We reserve the right to request components for evaluation. This warranty does not cover any mower that has been subject to misuse, neglect, negligence, or accident, or that has been operated in any way contrary to the operating instructions as specified in the Operator’s Manual. * Engines and electric starters are covered by the engine manufacturer’s warranty period. * Major drive system components are warranted for two (2) years by Scag Power Equipment. (Parts and labor 1st year; Parts only 2nd year) (T wo year warranty exclude fittings, hoses, drive belts). The repair or replacement of the hydraulic pump or hydraulic motor will be at the option of Scag Power Equipment.

The Scag mower, including any defective part must be returned to an Authorized Scag Service Dealer within the warranty period. The expense of delivering the mower to the dealer for warranty work and the expense of returning it to the owner after repair will be paid for by the owner. Scag’ s responsibility is limited to making the required repairs and no claim of breach of warranty shall be cause for cancellation or rescission of the contract of sale of any Scag mower.
This warranty does not cover any mower that has been subject to misuse, neglect, negligence, or accident, or that has been operated in any way contrary to the operating instructions as specified in the Operator’s Manual. The warranty
does not apply to any damage to the mower that is the result of improper maintenance, or to any mower or parts that have not been assembled or installed as specified in the Operator’s Manual and Assembly Manual. The warranty does not cover any mower that has been altered or modified, changing performance or durability. In addition, the warranty does not extend to repairs made necessary by normal wear, or by the use of parts or accessories which, in the reasonable judgment of Scag, are either incompatible with the Scag mower or adversely affect its operation, performance or durability .
Scag Power Equipment reserves the right to change or improve the design of any mower without assuming any obliga­tion to modify any mower previously manufactured. All other implied warranties are limited in duration to the two (2) year
warranty period or ninety (90) days for mowers used for rental purpose. Accordingly, any such implied warranties including merchantability, fitness for a particular purpose, or otherwise, are disclaimed in their entirety after the expiration of the appropriate two year or ninety day warranty period. Scag’s obligation under this warranty is strictly and exclusively limited to the repair or replacement of defective parts and Scag does not assume or authorize anyone to assume for them any other obligation. Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you.
Scag assumes no responsibility for incidental, consequential or other damages including, but not limited to, expense for gasoline, expense of delivering the mower to an Authorized Scag Service Dealer and expense of returning it to the owner , mechanic’s travel time, telephone or telegram char ges, rental of a like product during the time warranty repairs are being performed, travel, loss or damage to personal property, loss of revenue, loss of use of the mower, loss of time or inconve­nience. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limita­tion or exclusion may not apply to you. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
