Section 2 INTRODUCTION Your mower is only as safe as the operator. Carelessness or operator error may result in serious bodily injury or death. Hazard control and accident prevention are dependent upon the awareness, concern, prudence, and proper training of the personnel involved in the operation, transport, maintenance and storage of the equipment.
DO NOT allow children to ride or play on the machine, it is not a toy. Clear the area to be mowed of objects that could be picked up and thrown by the cutter blades. DO NOT carry passengers. DO NOT operate the machine under the influence of alcohol or drugs.

Section 2 Stay two cut widths away from slopes, drop offs, ditches and retaining walls. To prevent tipping or loss of control, start and stop smoothly, avoid unnecessary turns and travel at reduced speed. When using any attachment, never direct the discharge of material toward bystanders or allow anyone near the machine while in operation.
ROLL-OvER PROTECTION SYSTEM WARNING keep the roll bar in the raised and locked position and the seat belt securely fastened during operation. Failure to do so could cause serious injury or loss of life. This mower has been designed for good traction and stability under normal mowing conditions.

Section 2 The potential exposure of the seat belt to severe environmental 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...
MAINTENANCE CONSIDERATIONS & STORAGE Never make adjustments to the machine with the engine running unless specifically instructed to do so. If the engine is running, keep hands, feet, and clothing away from moving parts. Disengage drives, lower implement, set parking brake, stop engine and remove key or disconnect spark plug wire to prevent accidental starting of the engine when servicing or adjusting the machine.

OPERATING INSTRUCTIONS CAUTION Do not attempt to operate this mower unless you have read this manual. Learn the location and purpose of all controls and instruments before you operate this mower. CONTROLS AND INSTRUMENT IDENTIFICATION Before operating the mower, familiarize yourself with all mower and engine controls.
Section 4 Hourmeter (Figure 4-1). Indicates the number of hours the engine has been operated. It only operates when the engine is running. Has preset maintenance reminders for engine and hydraulic system oil changes. Will start flashing scheduled maintenance 2 hours before preset time and continue flashing until 2 hours after.
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. Make sure the fuel valve is completely open on the LP tank.
Section 4 REvERSE TRAvEL 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.
HILLSIDE OPERATION WARNING DO NOT operate on steep slopes. To 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.
Section 4 4.11 MOvING MOWER WITH ENGINE STOPPED To “free-wheel” or move the mower around without the engine running, rotate the dump valve levers counter- clockwise. See Figure 4-4. Disengage the parking brake and move the mower by hand. When the machine is in the desired position, engage the parking brake and rotate the levers clockwise until they stop.
Insert the lanyard pin into the cutting height index at the desired cutting height. Push forward on the deck lift foot lever, hold in place and pull back on the deck release lever. See Figure 4-6. Slowly release the foot pedal.
Section 4 4.16 TOWING (OPTIONAL HITCH ACCESSORY) NEVER allow children or others in or on towed equipment. Tow only with a machine that has a hitch designed for towing. Do not attach towed equipment except at the hitch point. Follow manufacturer's recommendations for weight limit for towed equipment.

Section 6 PARkING BRAkE ADJUSTMENT WARNING Do not operate the mower if the parking brake is not operable. Possible severe injury could result. The parking brake linkage should be adjusted whenever the parking brake lever is placed in the “ENGAGE” position and the parking brake will allow the mower to move.
TRAvEL ADJUSTMENTS Neutral or tracking adjustments will need to be made if: A. The steering control levers are in the neutral position and the machine creeps forward or backward. (Neutral Adjustment, See Below). B. The steering control levers are in the full forward position and the mower pulls to one side or the other when traveling in a forward direction.
Section 6 Actuate the steering control levers forward and reverse several times and return them to the neutral position. Check that the drive wheels remained in neutral and readjust if necessary. Check that the steering control levers hit the stop before the pumps reach full stroke.
BELT 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 center for belt adjustment. 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.
Page 31
Section 6 - NOTe - To prevent the cutter deck from teetering, all four (4) 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.
Page 32
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 seven (7) different positions for optimum performance.
Section 6 ELECTRIC CLUTCH ADJUSTMENT The electric clutch serves two functions in the operation of the mower. In addition to starting and stopping the power flow to the cutter blades, the clutch also acts as a brake to assist in stopping blade rotation when the PTO is switched off or the operator presence circuit is interrupted.

Section 7 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.
C. CHANGING HYDRAULIC OIL FILTER ELEMENT The hydraulic oil filter should be changed after every 500 hours of operation or annually, whichever occurs first. Remove the oil filter element and properly discard it. See Figure 7-3. Fill the new filter with clean oil and install the filter.
Section 7 WARNING DO NOT overfill. Follow approved procedures for filling. This cylinder is designed to contain LP Gas; a flammable liquid and gas under pressure. DO NOT expose to fire or heat above 120 degrees Farenheit. Be sure all fittings are tight and leak proof. DO NOT attempt repairs.
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.
Section 7 CUTTER BLADES A. BLADE INSPECTION Remove the ignition key before servicing the blades. Raise the mower deck to the highest position. Place the lanyard pin in the highest cutting height position to prevent the cutter deck from falling. WARNING Always wear proper hand and eye protection when working with cutter blades.
