CAUTION, WARNING, or DANGER—“personal safety instruction.” Failure to comply with the instruction may result in personal injury or death. Safe Operating Practices 1 The following instructions are from ANSI standard B71.4—1999. m–3775 Figure 1 Training 1. Location of the model and serial numbers • Read the Operator’s Manual and other training material. If the operator(s) or mechanic(s) can not read English it is the owner’s responsibility to explain this material to them.
• Never run an engine in an enclosed area. • Clean grass and debris from cutting unit, drives, mufflers, and engine to help prevent fires. Clean up oil or fuel spillage. • Only operate in good light, keeping away from holes and hidden hazards. • Let engine cool before storing and do not store near flame. • Be sure all drives are in neutral and parking brake is engaged before starting engine. • Shut off fuel while storing or transporting. Do not store fuel near flames or drain indoors.
• Keep hands, feet, hair and loose clothing away from attachment discharge area, underside of mower and any moving parts while engine is running. Service • Never store the machine or fuel container inside where there is an open flame, such as near a water heater or furnace. • Stop the engine before removing the grass catcher or unclogging the chute. • Mow only in daylight or good artificial light. • Keep nuts and bolts tight, especially the blade attachment bolts. Keep equipment in good condition.

Installing the Front Casters 1 1. Align casters with holes on top and front of mower and insert 8 bolts (3/8 x 3/4 in.) through mower. Secure with 8 flange nuts (3/8 in.) below mower (Fig. 2). 5 6 Note: Tighten lower bolts first to pull caster against front, then top bolts last. 4 2. Torque bolts to 30–35 ft. lb.

3. Check the gap between upper control bar and fixed bar with wheel drive fully engaged. Gap should be approximately 1 to 1-1/4 in. (25–32 mm) (Fig. 7). Note: The upper control bar and fixed bar must be parallel in the engaged, relaxed and brake positions. 1 4 4. Check operation. If adjustment is required, remove hairpin cotter securing rod to upper control bar. Thread rod in or out of trunion for proper position and install into upper control bar with hairpin cotter. 3 2 m–3782 Figure 5 1.
Installing the Shift Lever 6. Remove alignment pin and check control operation. 1. Remove the locknut (3/8 in.) and spring disk washer from the stud on top of the transmission. 3 Note: Do not remove rubber seal washer and square hole washer from transmission shaft. 7 4 2 2. Slide shift lever through control panel and align mounting hole in lever with square on transmission shaft. Secure lever to transmission with previously removed spring washer and locknut (Fig. 10). 6 1 3.
Note: Tighten left side of control panel until it is completely tight and then unscrew locknut one full turn. This will allow the spring to work. Caution This machine produces sound levels in excess of 85 dBA at the operator’s ear and can cause hearing loss through extended periods of exposure. Wear hearing protection when operating this machine. 4 3 3 2 5 6 1 m–3771 1 Figure 11 1. Bolt, 5/8 x 7/8 in. 2. Lock washer, 5/16 in. 3. Washer, 5/16 in. 2 Figure 13 4. Stud 5. Spring 6. Locknut 1.

To disengage the blade(s), pull blade control lever rearward, all the way (Fig. 17). 5. Close the fuel shut off valve before transporting or storing machine.
Testing the Safety Interlock System 1 Test the safety interlock system before you use the machine each time. If the safety system does not operate as described below, have an Authorized Service Dealer repair the safety system immediately. 1. Set the parking brake, disengage the PTO and place the throttle forward. Start the engine. With the engine running squeeze the bail against upper control bar and push the mower blade control lever forward. The mower blades begin rotating. 2 m–4194 2.
Using Side Discharge or Mulch Grass Note: Lifting up on handle will assist driving the machine up a curb and not spin the drive wheels. This mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. 1 Danger 2 Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death.

Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Important Refer to your engine operator’s manual for additional maintenance procedures.
Caution Someone could accidently start the engine and seriously injure you or other bystanders. Disconnect the wire from the spark plug(s) before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug. Servicing the Cutting Blades To ensure a superior quality of cut, keep the blades sharp. For convenient sharpening and replacement, you may want to keep extra blades on hand.
6 5 4 4 MEASURE FROM CUTTING EDGE TO A LEVEL SURFACE 1 3 m–2558 Figure 26 2 2. Rotate the opposite ends of the blades forward. m–3779 3. Measure from a level surface to the cutting edge of the blades at the same position as in step 1 above. The difference between the dimensions obtained in steps 1 and 2 must not exceed 1/8 in. (3 mm). If this dimension exceeds 1/8 in. (3 mm), the blade is bent and must be replaced. Refer to Removing the Blades, and Installing the Blades on page 26. Figure 27 1.
Installing the Blades 2 1. Place the blade onto the bolt, over cone washer. Select proper number of spacer(s) for height-of-cut and slide bolt into spindle (Fig. 27). 1 6 3 4 Important The curved part of the blade must be pointing upward toward the inside of the mower to ensure proper cutting. 2. Install remaining spacer(s) and secure with thin washer and nut (Fig. 27). 5 3. Torque the blade bolt to 75–80 ft. lb. (101–108 N m). m–4803 Figure 30 Servicing the Air Cleaner 1. Cover nut 2.

Rubber seal Checking the Engine Oil Level Installing the Foam and Paper Elements 1. Disengage the blade control (PTO) and set the parking brake. Important To prevent engine damage, always operate the engine with the complete foam and paper air cleaner assembly installed. 2.
Changing the Engine Oil spark plug wrench for removing and installing the spark plug(s) and a gapping tool/feeler gauge to check and adjust the air gap. Install a new spark plug(s) if necessary. 1. Start the engine and let it run five minutes. This warms the oil so it drains better. Type: Champion RJ19LM (or equivalent) Air Gap: 0.030 in. (0.76 mm) 2. Park the machine so that the drain side is slightly lower than the opposite side to assure the oil drains completely.
2 Cleaning the Cooling System 3 Service Interval/Specification 1 Before each use, check and clean engine cooling system. Remove any build–up of grass, dirt or other debris from the cylinder and cylinder head cooling fins, air intake screen on flywheel end, and carburetor–governor levers and linkage. This will help insure adequate cooling and correct engine speed and will reduce the possibility of overheating and mechanical damage to the engine. 0.030 in. (0.
Servicing the Brakes Service Interval/Specification Before each use, check brakes for proper operation. Always set the parking brake when you stop the machine or leave it unattended. If the parking brake does not hold securely, an adjustment is required. Checking the Brakes m–3780 1. Park the machine on a level surface, disengage the blade control (PTO) and set the parking brake. Figure 38 2. Rear wheels must lock when you try to push the machine forward or backward.

Disengage the blade control (PTO) and set the parking brake. 2.
5 4 Adjusting Mower Belt Tension 3 Service Interval/Specification Check belt tension after the first 8 and 25 hours of operation. Check the belt tension every 50 hours. 2 Important Belt must be tight enough to not slip during heavy loads while cutting grass. Over tensioning will reduce belt and spindle bearing life. 1. Disengage the blade control (PTO) and set the parking brake. 1 m–4739 2. Stop the engine and wait for all moving parts to stop before leaving the operating position. Figure 48 1.
Replacing the Grass Deflector 3 Warning An uncovered discharge opening could allow the lawn mower to throw objects in the operator’s or bystander’s direction and result in serious injury. Also, contact with the blade could occur. 2 Never operate the lawn mower unless you install a cover plate, a mulch plate, or a grass chute and catcher. 1 m–4727 Figure 49 1. Spring mounting bolts 2. Blade brake pad 1. Remove the locknut, bolt, spring and spacer holding deflector to the mounts (Fig. 51). 3.
