OPERATING INSTRUCTIONS

A. Controls

1. Ignition Switch:

(Recoil Start)

Located in the center of the control panel between the handles. When the key is inserted and turned clockwise

90 degrees, the engine can be started if the transmission shift lever is in neutral and the blade clutch is disengaged.

(Electric Start)

Located in the center of the control panel between the handles. When the key is inserted and turned clockwise

90 degrees, the engine will start if the transmission shift lever is in neutral and the blade clutch is disengaged.

2. Fuel Shutoff Valve:

Located under the fuel tank in the opening of the handle mount frame. The handle turns 90 degrees. When the handle is in a horizontal position, it will shut off the flow of fuel to the engine. When it is turned to a vertical position, it will open and allow fuel to flow to the engine.

Anytime the mower is being trailered or, if the mower will not be in use for 30 minutes or more, close the fuel shutoff valve to prevent flooding the engine.

3. Engine Throttle:

Located on the right side of the control panel between the handles. Moving the throttle lever from the front to the rear will increase the engine speed from slow to fast.

To start the engine, set the throttle all the way to the rear in the “Choke” position. After the engine starts, move the throttle halfway between slow and fast.

4. Recoil Starter:

Located on the top of the engine. To start the engine,

6 set the throttle on “Choke” and grasp the starter grip and pull slowly until the starter engages. Then pull the cord rapidly to overcome compression, prevent kickback and start the engine. Repeat if necessary with the throttle pushed halfway back to the “Slow” position.

Figure 2 View Looking Under The Fuel Tank

2. Fuel Shutoff Valve 5. Transmission Shift Lever

6. Blade Clutch:

Located on the left handle just below the control panel.

This is an over-center belt clutch and when the handle is pushed forward until it snaps to rest, it forces the idler pulley into the blade drive belt which causes the blades to rotate. When the handle is pulled back, the pressure on the belt is relieved and the blades will stop rotating.

7. Steering Brake Levers:

There is a right-hand lever located beneath the outer end of the right handle and a left-hand lever located beneath the outer end of the left handle. Each lever operates independently and when squeezed against spring tension, lifts the idler pulley from applying pressure to the traction drive belt on the right or left side and applies the right or left side brake. When the levers are released, the mower will move ahead in a straight line if the engine is running and the transmission is engaged in a forward gear. Steering is accomplished by squeezing the steering/brake lever on the side to which the turn is to be made.

8. Neutral Latch Levers:

Pivoted inside each handle there is a neutral latch lever which works with each of the steering/brake levers.

When either of the steering/brake levers is squeezed and its neutral latch lever pushed forward and engaged in the neutral lock position, the steering/brake lever is held in a position where the idler pulley is not applying pressure to the traction drive belt and the brake is not quite engaged. The neutral latch levers should be engaged in the neutral lock position before starting the engine.

9. Operator Presence Levers:

Located above the outer ends of the right and left handles, these levers must be held down on the handles against spring pressure in order to shift the transmission shift lever into gear or engage the blade clutch.

Releasing the operator presence levers with either the transmission shift lever in gear or the blade clutch engaged will shut off the engine.

B. Initial Adjustments

1.

Disconnect the spark plug wire.

2.

Check the tire pressure. Drive Wheels should be inflated to 25 psi. Caster Wheels should be inflated to 15 psi.

Note: New tires are overinflated in order to properly seat the bead to the rim.

3.

Check that all nuts, bolts and screws are tight.

4.

Check the tension of the deck drive belts: a. Remove the deck cover shield and engage the blade clutch.

b. Make sure the belts clear the belt guides by 1/8" to

1/4".

c. The tension of the deck drive belts should be adjusted so that a ten-pound pull between two pulleys deflects each belt about 1/2". Do not overtighten these belts. The blade clutch should engage with only moderate force.

d. Replace the deck cover shield and disengage the blade clutch.

5.

The tension of the transmission drive belt should be adjusted so that a five-pound pull between the engine traction drive pulley and the transmission drive pulley deflects the belt about 3/16".

6.

The two drive wheel belts are self-adjusting.

7.

The steering control rods on each side of the handle assembly should initially be adjusted so that there is about a 1/4" space between the rod and the bottom of the slot in the neutral latch lever with the latch in the drive position. To make this adjustment, remove the large hairpin from the swivel joint at the bottom of each steering control rod and thread the swivel joint up or down the rod as needed.

8.

The brake rods (above each drive wheel) should be adjusted so that when the steering/brake levers are squeezed and the mower is pulled backward, the brakes lock the drive wheels. The machine should roll freely when the neutral latch lever is in the neutral lock position. To adjust the brake rods, remove the large hairpin from the swivel joint at the top of each brake rod and thread the swivel joint up or down the rod as needed.

9.

Adjusting the cutting height: The mower is shipped with the cutting height set at 3 inches ±1/4 inch depending on the air pressure in the tires. To change the cutting height, blade spacers and/or caster spacers must be moved according to the table on page 6.

10. Lubricate all fittings listed in the maintenance section.

C. Break-In and Operation:

1.

Make certain you thoroughly understand all of the safety precautions before you attempt to operate this machine.

2.

Check the engine oil level. Fill to the proper level with straight 30 weight engine oil rated for service SE or SF.

7


3.

Move the mower outdoors. Check the engine gasoline level. When filling the tank, stop when the gasoline reaches one inch from the top. This space must be left for expansion. Use fresh, clean, unleaded, regular gasoline.

4.

Move the mower to a “test area” where you can operate the mower for about half an hour without being disturbed.

5.

To start the engine: a.

Shift the transmission to neutral.

b.

Disengage the blade clutch.

c.

Place the neutral latch levers in the neutral lock position.

d.

Connect the spark plug wire.

e.

Open the fuel shutoff valve.

f.

Move the throttle lever to the “Choke” position.

g.

Put the key in the ignition switch and turn the switch on. (For electric-start engines: Turn the key to “Start”.

Do not hold the key in the start position for more than

10 seconds or you may damage the starter.) h.

For recoil-start engines: Grasp the starter grip and pull slowly until the starter engages and then pull the cord rapidly to overcome compression, prevent kickback and start the engine. Allow the cord to recoil slowly. Repeat if necessary.

i.

Set the throttle at 50% of full engine RPM and allow the engine to warm up. Then, adjust the throttle to full engine RPM.

6.

After the engine has warmed up, shut off the ignition and check the operation of the safety switches. Make certain that the engine will not start unless the ignition switch is turned on, the transmission is in neutral and the blade clutch is disengaged. If the engine will start with the transmission in any gear other than neutral, immediately shut off the engine and replace the neutral safety switch on top of the transmission. If the engine will start with the blade clutch engaged, immediately shut off the engine and adjust or replace, if necessary, the blade safety switch mounted on the engine deck.

Start the engine and hold the left operator presence control lever down against the left handle and move the transmission shift lever into first gear. Now take your hand off the operator presence control lever and the engine should die. If it does not, immediately shut off the engine and adjust or replace, if necessary, the operator presence switch under the control panel. Shift the transmission into neutral, restart the engine, hold the left operator presence control down against the left handle and engage the blade clutch. Now take your hand off of the operator presence lever and the engine should die.

If it does not, immediately shut off the engine and adjust or replace, if necessary, the operator presence switch under the control panel. Disengage the blade clutch.

7.

Restart the engine.

8.

Push the blade clutch lever forward until it engages and the cutter blades start rotating.

9.

Shift the transmission into first gear. (It is suggested that you practice mowing in first gear.)

10. Squeeze both steering/brake levers with both hands and release the neutral latch levers from the neutral lock position.

11. Slowly release the steering/brake levers and the mower will move ahead in a straight line. To turn the mower, squeeze the steering/brake lever on the side to which you want to turn.

12. To stop the mower’s forward motion, squeeze both steering/brake levers until the mower stops and place the neutral latch levers into the neutral lock position.

13. Before shifting into reverse gear, the mower’s forward motion must be completely stopped. For maximum traction in reverse, the steering/brake levers should be pushed downward.

WARNING:

To avoid possible bodily injury and to prevent damage to the transmission, the mower must be completely stopped before attempting to shift the transmission.

14.Practice operating the mower and as you gain confidence, shift the transmission from first to second and mow for a while and then shift from second to third.

Mow for at least one-half hour and then return the mower to the shop.

15. To stop and shut off the mower, squeeze both steering/ brake levers and place the neutral latch levers into the neutral lock position, disengage the blade clutch, shift the transmission into neutral, turn off the ignition to stop the engine, close the fuel shutoff valve and disconnect the spark plug wire.

16. Check that all nuts, bolts and screws are still tight.

17. Check, and adjust if necessary, the tension of the deck drive belts and the transmission drive belt as described in items 4 and 5 of the Initial Adjustment section.

18. Readjust the steering control rods and the brake rods.

They may require frequent adjustment until the belts and brake bands have properly seated. These adjustments are described in items 7 and 8 of the Initial

Adjustment section.

19. After the first full day of mowing, all nuts, bolt and screws should be rechecked for proper tightness and the belts should be rechecked for proper tension.

8

CUTTING HEIGHT ADJUSTMENT TABLE

Note: The front edge of the cutting deck should be 1/8” - 1/4” below the rear edge of the deck so that the blades are cutting grass in only the front half of their circular path. This decreases friction and reduces the drive power required.

7. TO CHANGE SPINDLE BEARINGS:

(See the exploded view drawing) a. Clamp the spindle assembly in a vise with the grease fitting pointing up.

b. Bend down the tab of the tab lockwasher.

c. Remove the hex jam nut.

d. Obtain a round wooden dowel about 6-inches long such as a piece of broom handle. Hold this wooden

12 dowel on top of the spindle and tap it with a hammer to drive the spindle out of the bearings and the spindle housing. e. Pull the seal spacer out of the top seal.

f. Using a large screwdriver, pry the seals out of each end of the spindle housing. (NOTE: You will destroy the old seals as you remove them.) As you remove the old seals, the inner races of the roller bearings and the internal spacer will fall out of the spindle housing.

g. Using a bearing puller, remove the outer races from both ends of the bearing housing. (NOTE: If the outer races cannot be removed using this procedure, take the spindle housing to a local machine shop and let them remove the bearing races.) h. Clean the old grease out of the spindle housing.

i. Clamp the housing in a vise with the grease fitting pointing down.

j. Gently drive a new bearing outer race back into the spindle housing using the wooden dowel. Make certain that the tapered side of the race faces outward.

k. Pack one inner race with fresh grease and place it into the outer race.

l. Press one of the new seals into the spindle housing by using the wooden dowel, moving around the circumference of the seal and tapping gently with a hammer. (NOTE: The metal surface of the seal should face outward.) m. Turn the housing over and re-clamp it in the vise with the grease fitting pointing up.

n. Gently drive the second bearing outer race back into the spindle housing using the wooden dowel. Make certain that the tapered side of the race faces outward.

o. Insert the internal spacer.

p. Pack the second inner race with fresh grease and place it into the outer race.

q. Press the second new seal into the spindle housing by using the wooden dowel, moving around the circumference of the seal and tapping gently with a hammer. (NOTE: The metal surface of the seal should face outward.) r. Coat the spindle with grease and push it up through the bottom of the spindle housing. The spindle will pass through the lower seal, an inner race, the internal spacer, an inner race and the upper seal.

s. Hold the spindle in place and install the seal spacer down over the spindle and push it into the top seal.

There is a notch on one of the inside edges of the seal spacer that should be facing up and should be opposite the side of the spindle with the keyway.

Install the new tab lockwasher with its bent inner tab pointing down to engage with the notch in the seal spacer. Install the hex jam nut and tighten it. Bend up the large tab on the tab lockwasher to hold the jam nut in place.

8. TO ADJUST THE LITE-TOUCH (MANUALLY)

a.rThree holes in the belt guard allow you to reposition the hex cap screw to adjust the brake lever. The top hole (lite tension), the middle hole

(medium tension) and the lower hole (hard tension). The unit is shipped with the hex screw in the top hole. SEE THE FIGURE BELOW FOR

REFERENCE. To adjust the bolt do the following: b.With a spring puller, pull the spring and detach it from the hex cap screw.

c.Remove the lock nut from the lite touch hole in the belt guard.

d.Loosen (but do not remove) the remaining two nuts on the belt guard.
