ENGINE SPEED: Set at factory. The engine runs at a constant speed.

FUEL VALVE: Move fuel valve to "ON" position (when provided on engine).

1.Select desired cutting height before starting engine.

2.Place mower on a sidewalk or driveway where the mower blade is in an unloaded condition. If it must be started on the lawn, move mower over previously cut grass.

3.Be sure drive bail is not engaged.

4.Prime to choke.Prime is located in front of the engine.

5.Pull back on operator presence control, then pull back on starter rope slowly until resistance is felt. Then pull cord rapidly to start. Repeat if necessary.

16.2CUTTING OPERATION

CAUTION: The mower blade will be rotating whenever engine is running.

CAUTION: Stop Blade when crossing gravel drives, walks or roads and under all conditions where thrown objects might be a hazard.

CLEARING A CLOGGED CUTTING DECK: Turn engine off and wait for blade to stop completely. Disconnect spark plug wire.

Wearing durable gloves, remove clog. Danger, the clog may contain sharp materials. Reconnect spark plug wire.

CAUTION: Use extreme care when operating the blade. Inspect the work area for foriegn objects that could cause damage to the unit or injure the operator if struck by the blade. Never operate the blade with bystanders in the work area.

16.3 CUTTING HEIGHT ADJUSTMENT

CAUTION: DO NOT make cutting height adjustment when engine is running.

Cutting height can be adjusted from 2" to 4" by 1/2" increments by lowering or rasing the deck. For easiest adjustment change the height from one side at a time. To change cutting height, remove lock pins, raise or lower deck to desired height, then reinsert lock pins. Repeat this step on other side

NOTE: Be sure that the deck is level. Running the deck out of level will result in poor cut quality and increased belt wear.

Fig. 2

DRIVE

 

 

BAIL

GROUND SPEED can be varied by selecting a higher or lower gear using the gear shift lever on top of the handle (See Fig. 3). Under most conditions cutting should be done in first or second gear. Third gear should be reserved for conditions where weeds and brush are thinned out or not as tall. The quality of the cut produced is directly related to the unit's ground speed during cutting. If the quality of the cut is not satisfactory (i.e. material left standing) you should shift into a lower gear during cutting. For improved control in confined areas, this machine can be pushed forward or backward by releasing the drive bail located at the back of the handle.

WARNING! Never mow on any slope greater than 15 degrees. Always mow across the face of slopes; never up and down or diagonally see fig 5.1). DO NOT attempt sudden starts or stop when mowing on a slope. Avoid Sudden turns and use extreme cauton when

changing direction on a slope.

16.6HANDLING & TRANSPORTING:

Using two people to lift machine is recommended. Lift holding the handle and front of deck. Secure in place during transport.

16.7STORAGE

Never store engine indoors or in enclosed poorly ventilated areas with fuel in tank, where fuel fumes may reach an open flame, spark or pilot light, as on a furnace, water heater, clothes dryer or other gas appliance.

If engine is to be unused for 30 days or more, prepare as follows:

Be sure engine is cool. Do not smoke. Remove all gasoline from carburetor and fuel tank to prevent gum deposits from forming on these parts and causing possible malfunction of engine. Drain fuel outdoors, into an approved container, away from open flame. Run engine until fuel tank is empty and engine

runs out of gasoline.

NOTE: Fuel stabilizer (such asSta-Bil)is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage container. Always follow mix ratio found on stabilizer container. Run engine at least 10 min. after adding stabilizer to allow it to reach the carburetor.

CAUTION: Wheels must be chocked or blocked when unit is parked on a slope.

17.1 BLADE REMOVAL / SHARPENING

17.2

BELT REPLACEMENT

NOTE: When sharpening the blade it is a good idea to check the balance of the blade. A properly balanced blade will increase life of the bearings and other components.

Tools required: 3/8 inch socket, 5/8 inch socket, torque wrench, blade block.

1.Disconnect spark plug wire.

2.Remove 5 screws (item 76) then remove belt guard (19).

3.Set the unit on its side to allow access to both pulley and the blade.

Note: When tipping the unit on its side, keep the air cleaner side of engine up. Be sure the gas is drained out to prevent from spilling before tipping the unit on its side. Never tip the mower more than 90 degrees and do not leave the mower tipped for any length of time.

4.While protecting your hands with pair of gloves or heavy rag to hold the blade, loosen but do not remove the bolt (88) on the pulley side (fig. 6).

5.Remove jam nut (68), blade washer (43), blade (44), blade washer (43), and blade spacer (39).

6.Replace or sharpen the blade then install in the exact order they were removed (fig. 7).

7.Tighten the jam nut until it is flushed with the end of the shaft (fig 7). Then tighten the bolt on the pulley side - Torque it to 80 ft-lbs.

Note: When replacing the blade use B.G.I. Part no. 510107.

8.Reinstall belt guard then connect spark plug.

Note: Before installing the fasteners inspect them for wear and replace as necessary.

When replacing one belt the other should be inspected for wear and replaced if worn. It is good practice to change both belts when either is worn beyond use. Use only original equipment belts for replacement. Billy Goat uses only premium quality, kevlar corded and coated belts in your unit. Substitute belts do not meet the design and performance requirements for your unit , and will greatly reduce machine performance and belt life.

Blade Drive Belt

Tools required: 3/8 inch socket, 1/2 inch socket, 3/8" torque wrench.

1.Disconnect spark plug wire.

2.Set the deck height to middle position (3 inches cutting height).

3.Remove 5 screws (item 76) then remove belt guard (19).

4.Loosen but do not remove the nut (71) at the top of the engine base located just front of the engine. This will release the tension on the blade drive belt (37). NOTE: It may be necessary to loosen bolt (85) in order to allow idler pulley bracket to pivot .

5.Replace the old belt with the new belt.

Note: Use only O.E.M. approved belt for this machine - B.G.I. Part no. 510139.

6.To adjust tension on the new belt, insert 3/8" torque wrench in the idler bracket, apply 10 lbs. of torque then tighten the nut (71) on top of the engine base (fig. 8).

Note: Belt requires very little tension to drive the blade. Over tensioning the belt will greatly reduce the life of the belt.

7.Install belt guard using 5 screws (76)

8.Reconnect spark plug wire.

Note: Start the unit up and cut grass to make sure the blade belt is not slipping.

Tools required: two 1/2 wrenches.

As the clutch wears, adjustments may be required to maintain proper control cable tension, and clutch engagement (fig. 11). If the clutch begins slipping or squealing during normal operation it may require an adjustment to increase the clutch cable tension. A properly adjusted drive clutch should require a minimum of 3/8" of spring stretch when drive bail is engaged.(fig. 12) Adjust by tightening or by loosening clutch cable adjusting nut as required, located at the underneath the engine base (fig. 13). Replacement of cable may be necessary if adjustment will not allow for proper drive clutch.

WARNING: If the drive clutch begins to squeal or slip,do not continue to operate your unit until adequate adjustment or repair has been performed. Improper adjustment can cause drive clutch to slip and overheat, greatly reducing machine performance and transmission life.
