SAFETY WARNING: This cutting machine is capable of amputating hands and feet and throwing objects. Failure to observe the safety instructions in the manuals and on decals could result in serious injury or death. Slopes are a major factor related to loss-of-control and tip-over accidents. Operation on all slopes requires extra caution. Tragic accidents can occur if the operator is not alert to the presence of children. Never assume that children will remain where you last saw them.
6 2 5 4 1 3 2 OF0002 Figure 2 1. DANGER! TO AVOID SERIOUS INJURY OR DEATH • • • Read Owner/Operator Manual. • OL1801 • Keep children and others away from unit while operating. • If machine stops going uphill, stop blade and back down slowly. Avoid sudden turns. Keep safety devices (guards, shields, switches, etc.) in place and working. Check interlock system per manual before use. Understand location and function of all controls. Never allow operation by untrained persons. 2.
NO STEP! Always keep feet away from rotating parts. OL4420 3. WARNING! Do not operate mower unless guards are in operating position or bagger is attached. Always stand clear of discharge area. OL4430 Do not operate mower unless bagger is attached or guards are in operating position. OL3320 4. HOT SURFACES! DO NOT touch parts which are hot from operation. ALWAYS allow parts to cool. OS0731 5. ROTATING PARTS AVOID INJURY. Stay clear of rotating parts. OF3450 6. DANGER! AVOID INJURY.
Always wear safety goggles or safety glasses with side shields when operating mower. Moving parts can cut or amputate fingers or a hand. Wrap blade(s) or wear gloves to service. On multiblade mowers, rotation of one blade will cause all blades to rotate. NEVER place your hands or any part of your body or clothing inside or near any moving part while unit is running. ALWAYS keep hands and feet away from all rotating parts during operation. Rotating parts can cut off body parts.
Always wear a seat belt when operating unit using a Rollover Protection System (ROPS). Keep all movements on the slope slow and gradual. Do not make sudden changes in speed or direction. Avoid starting or stopping on the slope. If tires lose traction, disengage the blades and proceed slowly straight down the slope. If you cannot back up a slope or you feel uneasy on it, do not mow it. DO NOT park on slopes unless necessary. When parking on slope always chock or block wheels. Always set parking brake.
NEVER attempt to make any adjustments to unit while engine is running (except where specifically recommended). Stop engine, remove key or spark plug wire and wait for all moving parts to stop before servicing or cleaning. Check parking brake operation frequently. Adjust and service as required. ALWAYS maintain unit in safe operating condition. Damaged or worn out muffler can cause fire or explosion. Maintain or replace safety and instruction labels, as necessary.
7. Check Engine Crankcase - Check and add oil if needed. See Engine Manual for specifications. 8. Fill Engine Fuel Tank - Add clean fuel to the fuel tank. IMPORTANT: Refer to Engine Manual for fuel type. 9. Hardware - Check for loose hardware. 10. Check Safety Interlock System - Check to see that the interlock system operates correctly (See Safety Interlock System on page 12). 1 2 1 3 WARNING: FAILURE OF INTERLOCK together with improper operation can result in severe personal injury. 11.

OPERATION Steering Levers WARNING: AVOID INJURY. Read and understand entire Safety section before proceeding. A B C D CONTROLS AND FEATURES See Figure 4 for Controls and Features locations. 07757600B Safety Interlock System WARNING: Safety interlock system failure and improper operation of unit can result in death or serious injury. Test this system each time the unit is operated. If this system does not function as described, do not operate until repairs are made.
Choke Control OF1680 Mower Lift Pedal Push the choke lever forward to start a cold engine. Pull the choke lever to the rear when the engine gets warm. Throttle Lever The throttle lever changes the engine speed. Move the throttle lever to Fast (1) to increase engine speed. Move the lever to Slow (2) to decrease engine speed. 1 OF1700 Mower lift pedal raises and lowers mower deck for mowing or transport. Transport: Push mower lift pedal all the way forward until lift lock engages.
Hour Meter 4. Check Tire Pressure Records total number of hours the engine has been run. 5. Check Hydraulic Fluid Level IMPORTANT: Keep a record of Hour Meter readings for recommended Lubrication and Maintenance Be sure all controls can be reached safely from operator’s position. 6. Adjust Seat intervals. NOTE: For accurate readings be sure Ignition Switch is OFF when unit is not in operation. 7. Set Cutting Height Make sure the deck is set to the correct cutting height.
WARNING: Move the steering control levers slowly and keep the throttle control lever at slow speed until you learn how to operate the unit. 3. Bring the steering levers to neutral. 4. Slow the engine down to about 3/4 speed. 5. Turn ON the PTO switch to engage the mower. IMPORTANT: Never engage the PTO if the mower is plugged with grass or other material. This may cause damage to the electric clutch. 6. Move throttle control to fast. 7. Move the steering levers forward to obtain a slow ground speed. 8.
FOR BEST PERFORMANCE Mow with the engine set at full throttle. When mulching, only remove 1/3 of grass length per cutting. Do not cut more than 1 inch (2.54 cm) at any one time. Discharge clippings into areas already cut. Vary cutting pattern with each mowing. Do not allow grass or debris to collect inside of mower deck. Clean after each use. Cut grass when it is dry. Keep mower blades sharp. Keep mower deck properly levelled. Adjust anti-scalp rollers to prevent scalping.
Period Service Task Each Use Follow Engine Manual Maintenance Schedule Perform scheduled engine maintenance. Refer to engine manual for detailed instructions. Every 25 Hours Check Mower Blades Check mower blades for wear. Sharpen or replace as needed. See Mower Blades on page 19. Every 50 Hours Lubricate Unit Oil all pivot points and pin connections. Grease lube fittings. See Lubricate Unit on page 22. Check Brake Gap Adjust gap if nessessary. See Adjusting the Parking Brake on page 24.
Check Hydraulic Fluid Level 2 1 Check the system with the unit cold and parked on a flat, level surface. Then run the unit for about one minute and recheck the levels. 2 To Add Hydraulic Fluid: 1.
