HYDRAULIC SAFETY

1. Hydraulic fluid is under high pressure. If you need service on your hydraulic system, please see your dealer.

Keep your body and hands away from pin holes or nozzles that eject fluid under high pressure. Use paper or cardboard, not hands, to search for leaks.

Hydraulic fluid escaping under high pressure may have sufficient force to penetrate your skin and cause serious injury. If fluid is injected into your skin, a physician familiar with this form of injury must re- move it surgically within a few hours or gangrene may result.

2. Make sure all hydraulic fluid connections are tight and all hoses and lines are in good condition before applying pressure to the system.

ADJUSTMENTS

Neutral Adjustment

1. Set the machine up on jack stands so the drive wheels are free to rotate. Block the caster wheels to prevent an accident if the machine should acciden- tally fall off the jack stands.

2. Run Position: Move the dump valve lever (on the Left Hand side of mower) behind the hook on the frame to close the hydraulic dump valves on the pump. (See Figure 1)

Free Wheel Position: Pull lever back and to the left, then push forward to relieve pressure. (See Figure 1)

Figure 1

3. Start the engine and check if one or both of the drive wheels are turning.

4. Adjust each drive wheel separately by using the turnbuckles located under the seat. Loosen the jam nut on the turnbuckle. (See Figure 2)

5. If the drive wheel is rotating forward, adjust the turnbuckle clockwise. If the drive wheel is rotating rearward, adjust the turnbuckle counterclockwise. Adjust until the drive wheel stops turning. (See Figure 2)

Drive Belt Replacement

When replacing the drive system belt use ex- treme caution. The idler arm is under spring tension.

Remove the two 1/4" nuts on the belt guard and remove the guard. To remove the old belt, use a 1/2" drive breaker bar and insert it into the square hole on the idler arm. Pull the idler arm down until the belt becomes slack and can be removed easily from the idler pulley. Slowly move the idler arm up until the stop bolt rests against the hydraulic tank support. Remove the old belt and mount the new belt around the engine drive pulley and the two pump pulleys. Feed the belt up toward the idler pulley.

Pull the idler arm down so that the new belt can easily be mounted on the idler pulley. Slowly move the idler arm up until the belt is firmly engaged. Remove the breaker bar and remount the belt guard. Check to ensure that the belt is riding properly in all pulleys. ontrol Handle Position Hand Control Handle Position

The position of the hand control handles can be adjusted for operator comfort. Loosen the bolts holding the handle to the lever bar just enough to allow movement of the handle. Adjust to position most comfortable for operator. Retighten the bolts.

INITIAL RUN, INSPECTION, AND OPERATING INSTRUCTIONS

1. Check that all belts are routed correctly and aligned properly.

2. Check the cutter blade drive belts for correct tension.

!

3. Make sure the engine oil level (10W30) is at FULL on the dipstick. When performing oil changes, fill the engine to the full mark on the engine dipstick. (Approximately 2 quarts will be needed for Kohler engines) DO NOT OVERFILL.

4. Check the oil level (SAE 20W50) in the hydraulic reservoir. The reservoir is under the seat. The oil level should be 2" below the top of the tank. When performing oil changes, fill the reservoir until it is 2" below top of tank. (Approximately 4 quarts will be needed) DO NOT OVERFILL.

5. Check that all fasteners are tightened properly. Make sure all safety devices are in place and working correctly.

6. Fill the fuel tank with clean, fresh, lead-free gasoline with a minimum octane rating of 87.

7. Check the safety interlock system. With the operator on the seat, the engine must not start unless the control handles are in the neutral lock position and the cutter drive is disengaged.

IMPORTANT: If the engine is running, the engine must stop if the operator leaves the seat when one or both handles are in the drive position or the cutter drive is engaged.

WARNING: Gasoline is highly flammable. Be careful when filling the tank. Do not fill the tank while the engine is running or hot from operation. Ex- tinguish open flames, matches, and smoking materials before filling the tank. Do not over- fill the tank. Wipe up all gasoline spills.

CAUTION:

All other implied warranties are limited in duration to the one (1) 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 one year or ninety day warranty period. Scags 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, mechanics travel time, telephone or telegram charges, 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 incon- venience. 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.
