30. Shut off engine when not trimming

or mowing.

31. Use extra care when loading or unloading machine into a trailer or truck.

32. Use this equipment for its intended purpose only.

33. Always make sure the handlebars are tight and comfortably positioned. They should never be in an awkward position for the operator.

SLOPE OPERATION

Slopes are a major factor related to loss of control and tip-over accidents which can result in severe injury or death. All slopes require extra caution. If you can not back up the slope or you feel uneasy on a slope, do not mow it.

Do:

Mow across the face of slopes; never up and down. Exercise extreme caution when changing direction on slopes. Avoid slopes greater than 15o.

Remove objects such as rocks, tree limbs, etc.

Uneven terrain could overturn the machine. Watch for holes, ruts, or bumps. Tall grass can hide obstacles.

Use slow speed. Use extra care with grass catchers or

other attachments. These can change the stability of the machine. Keep all movement on the slopes slow and gradual.

Avoid starting or stopping on a slope.

Do Not:

Do not mow near drop-offs, ditches, or embankments. You could lose footing or balance.

Do not mow on very steep slopes. Do not mow on wet grass. Slippery

footing can be hazardous.

CHILDREN

Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them.

1. Keep children out of the mowing area and under the watchful care of a responsible adult.

2. Be alert and turn machine off if children enter the area.

3. Before and while moving backwards, look behind and down for small children.

4. Never allow children to operate the machine.

5. Use extra care near blind corners, shrubs, trees, or other objects that may obscure vision.

6. Never carry children, even with the trimmer head stopped. Children may fall off and be seriously injured or interfere with safe machine operation.

7. Do not allow children nearby if you are working.

SERVICE

1. Use extra care in handling gasoline and other fuels. They are flammable and their vapors are explosive. To help prevent a fire or explosion:

a) Use only an approved container. b) Never remove gas cap or add fuel

when the engine is running. Let engine cool before refueling. Do not smoke.

c) Never refuel the machine indoors.

Fill the fuel tank outdoors and with extreme care.

d) Never store the machine or fuel

container inside where there is an open flame, such as a water heater, etc.

Page 5

Section 1: Safety 3

e) Replace caps on the fuel tank and

fuel container and clean up spilled fuel before starting engine. Move machine away from any gasoline fumes before starting the engine.

f) Keep matches, smoking materials,

open flames, and sparks away from the fuel tank and fuel container.

g) Leave 1/2" air space at the top of

the fuel tank to allow for fuel expansion.

2. Never run the engine inside a closed area.

3. Never clean, or make adjustments or repairs with the engine running. Disconnect the spark plug wire and keep the wire away from the plug to prevent accidental starting. Remove key on electric start models.

4. Keep all nuts and bolts tight, especially the trimmer head attachment bolts, and keep equipment in good condition. Check mounting hardware on trimmer head every time you change trimmer line and prior to each use.

5. Never tamper with safety devices. Check their proper operation regularly.

6. To reduce fire hazard, keep mower free of grass, leaves or other debris build-up. Clean up oil or fuel spills. Let machine cool before storing.

7. After striking an object, stop the engine and disconnect the spark plug wire. Inspect the machine and repair, if necessary, before restarting.

8. Never make adjustments or repairs while engine is running.

9. Components subject to wear, damage and deterioration could expose moving parts or allow objects to be thrown. Frequently check components and replace with factory recommended parts, when necessary. Regularly inspect the trimmer head and debris shield. Make sure they are not bent, damaged, or loose.

10. Only use eighteen-inch long .130" or .155" diameter trimmer line. Never use other lengths, diameters or material as trimmer line.

11. Trimmer line moves at high speed and can cut. Always stop the engine and let all moving parts stop before replacing the trimmer lines. Let the engine cool.

12. Do not change the engine governor setting or overspeed the engine. The governor controls maximum safe operating speed and protects the engine and all moving parts from damage caused by overspeed. Authorized service shall be sought if a problem exists.

13. Do not touch engine parts which may be hot from operation. Allow parts to cool completely before inspecting, cleaning or repairing the unit.

14. Maintain or replace safety and instructional decals. Refer to the Parts List for replacement decal information.

15. Use only original-equipment replacement parts. Parts manufactured by others could present safety hazards and affect performance even though they may fit on this trimmer/mower.

16. Remember– the end of the season is a good time to inspect equipment prior to storage.

17. To guard against engine overheating, always keep the engine debris guard mounted and clean.

4. Securely replace the fuel tank cap and the fuel container cap. Promptly wipe up any fuel spills.

5. Lift and tilt the debris shield back, then push it down to secure it.

ADJUST HANDLEBAR HEIGHT

To adjust handlebar height, refer to “Install Handlebars” in the “Assembly” Section of this Manual.

ADJUST LINE CUTTING HEIGHT

The cutting height of the trimmer line can be adjusted between 1-1/2" and 4-1/2" high in infinite increments. Start at a higher setting and make adjustments as needed.

In general, use higher settings to handle taller material and to cope with tougher cutting conditions. Use any trimming height for less demanding conditions. To adjust the cutting height:

1. The cutting line height can be changed when the wear cup is resting on the ground. If necessary, tip the unit back slightly for a better view (do not tip unit all the way back or motor oil may flow to the exhaust area and the engine may smoke for several seconds when restarted).

2. Use a 1/2" wrench to loosen both bolts (A, Figure 4-1) securing the trimmer head. Do not try to loosen the two nuts.

3. The cutting heights are stamped into the spindle head (Figure 4-2). Move the top of the trimmer head to the desired setting.

4. Tighten both trimmer head bolts securely (to 75 in/lbs.) and equally.

Operation

Section

Before adjusting handlebar height, stop engine and wait for all moving parts to stop, disconnect spark plug wire and prevent it from touching spark plug.

Failure to comply could result in personal injury or property damage.

CAUTION

Before adjusting the cutting height, shut off the engine, wait for all moving parts to stop, allow the engine to cool, disconnect the spark plug wire and prevent it from touching the spark plug.

Failure to comply could result in personal injury or property damage.

CAUTION

GASOLINE IS HIGHLY FLAMMABLE AND ITS VAPORS ARE EXPLOSIVE.

8 Section 4: Operation

USE CORRECT DIAMETER TRIMMER LINE

For tougher cutting conditions, use two (or four) sections of the thicker, .155" diameter extra-heavy duty line.

For less demanding conditions, use two sections of the thinner, .130" diameter heavy-duty line.

The thicker line has the heft to chop through tougher materials, while the thinner line provides a more precise cut. To change trimmer lines, refer to “Changing Trimmer Lines” in Section 5.

NOTE: The thinner line is also recommended for use near trees or shrubs to help prevent girdling (cutting the bark).

HOW TO USE TRIMMER HEAD CONTROL BAIL

The Trimmer Head Control Bail (A, Figure 4-3) is used to start and stop trimmer head motion.

1. Leave the control bail in the disengaged (released) position when starting the engine to prevent the trimmer head from turning when the engine starts. See Figure 4-3.

2. When the engine is running, pull and hold the control bail up against the handlebar (Figure 4-4) to start rotation of the trimmer head.

3. Let go of the control bail to stop the trimmer head. The control bail should spring forward to the disengaged position. If it doesn’t, do not use the machine until the control bail has been repaired.

OPERATING THE MACHINE

Once you have read and understood the sections in this Manual on “Safety”,

“Assembly”, “Features and Controls”, and “Operation”, you are ready to start and

operate your machine.

OPERATING TIPS AND TECHNIQUES

Tips for Precision Cutting

For the most precise cutting possible, select the most appropriate line cutting height and trimmer line size (thickness) for the conditions.

Figure 4-3: Control bail disengaged.

Figure 4-4: Control bail engaged.

If the trimmer head control bail is not operating properly, shut off the engine, disconnect the spark plug wire and move wire away from plug.

Adjust or repair the control bail before using the trimmer/mower.

Failure to follow this instruction could result in personal injury or property damage.

WARNING

NOTE: If unit is operated in a stationary position with the wear cup in contact with dry vegetation, significant heat will result that may deform the plastic spindle or scorch vegetation.

Page 11

Section 4: Operation 9

When mowing, let the cutting head rest lightly on the ground and do not lift up or push down on the handlebars. This technique allows the cutting head to follow the ground contour closely, resulting in the most even cut possible. Also, be sure to ease into heavy growth to prevent overwhelming the machine.

Trim When Wet or Dry

Grass and most other materials are most efficiently trimmed when dry. But the unit will do a fine job even with damp or wet materials. When conditions are moist or damp, be sure to clean debris off the machine regularly to keep cutting efficiency high. And watch your footing!

Clean Unit Frequently

Clean under the mower deck frequently to remove any grass buildup. Also clean around the muffler and on top of engine. See the cleaning instructions in Section 5: “Maintenance.”

Do Not Let Trimmer Lines Become Too Short

Once the trimmer lines are worn to less than 1/2 their original length, trimming jobs begin to take far longer than they should. As a general guideline, once line length becomes half of its original length, it’s time to change to new lines.

Use Extreme Caution on Slopes

When operating on sloping ground, use extreme caution and common sense to avoid possible injury or property damage.

Do not mow on excessively steep slopes! Avoid slopes if greater than 15oor wherever footing is unsure. If a slope is difficult to stand on, it is probably too steep to trim or mow. In this case, it may be wiser to establish a permanent ground cover on this area.

Do not trim on slopes when the ground is slippery. Trim across the face of a slope, not up and down. Slow down and exercise caution when changing direction on slopes.

Use Correct Walking Speed

Use a travel speed that is suitable for the mowing conditions. You’ll get better results at slower walking speeds if the growth is tall or lush. Shorter or less dense growth can be cut at faster walking speeds.

Vary Throttle Speed For Conditions

The vast majority of trimming and mowing jobs will yield the best results if the engine throttle is set at the fastest engine speed.

Less demanding jobs (and projects that require very precise cutting) will yield better results if the engine speed is backed off somewhat. (For example, damage to trees and shrubs can be avoided by reducing the engine speed, using the lighter .130" diameter line, and by keeping a safe distance away.)

Again, once you begin a particular job and get a “feel” for the conditions, you will be able to make adjustments for the best possible results.

Keep Mowed Side to Your Right as You Move Ahead

The unit feeds cut materials to the right side. Stay on the right side of unmowed growth as you move along.

THROWN OBJECT HAZARD!

• Objects such as rocks, pebbles, and small debris will be thrown violently by the cutting head, resulting in significant hazard to eyes and exposed body parts.

• Always wear safety-approved eye protection and suitable clothing and footwear.

• Keep children, pets and bystanders 50 feet away from machine while operating.

• Be alert to hidden obstacles.

Failure to comply could result in injury or property damage.

Chart 5-1

Before inspecting, cleaning or servicing the machine, shut off engine, disconnect spark plug wire, and make sure that all moving parts have come to a complete stop. Remove ignition key on electric start models.

Failure to follow these instructions can result in personal injury or property damage.

WARNING

ADJUSTING TRIMMER HEAD ENGAGEMENT

The tension on the drive belt must be correct for proper operation of the trimmer head. If the tension is correct, the trimmer head will rotate when the Trimmer Head Control Bail is pulled back against the handlebar.

A loose or worn drive belt causes the trimmer head to move slowly, or not at all, when the control bail is engaged (belt squealing may also be noticeable).

If the belt tension is too tight, the trimmer head may rotate before the control bail is engaged, or when there is no free play in the control bail.

Belt Tension Adjustment

1. Stop the engine and wait for all parts

to stop moving. Disconnect spark plug wire and move it away from spark plug. Remove ignition key on electric start models.

2. Adjust the positions of the two jam nuts on the control cable adjuster (see Figure 5-2) as described below:

• To tighten belt tension:

Move the upper nut (A, Figure 5-2) upward one or two full turns, then move the lower nut (B) upward. Tighten both nuts securely. Test unit and readjust jam nuts as needed.

• To loosen belt tension:

Move the lower nut (B, Figure 5-2) downward one or two full turns, then move the upper nut (A) down. Tighten both nuts securely. Test the unit and readjust jam nuts as needed.

NOTE: LEFT and RIGHT sides of unit are as viewed from operator’s position behind the handlebars.

Failure to follow these instructions can result in serious personal injury or property damage.

REMOVING AND REPLACING TRIMMER HEAD

1. Stop the engine and wait for all moving parts to stop. Disconnect spark plug wire and move it away from the spark plug. Remove the ignition key on electric start models.

2. Two bolts (A, Figure 5-3) secure the trimmer head (B) to the spindle head (C). Loosen both bolts (not the nuts) just enough to open up the trimmer head and allow it to slide down the spindle head and past the two stops. Do not attempt to remove the bolts completely – they are permanently attached.

NOTE: It may be necessary to first remove the wear cup (D, Figure 5-3) when removing the trimmer head. See Step 4 for the procedure.

3. Install the new trimmer head on the spindle head. Tighten the hardware securely (to 75 in/lbs.) and evenly.

4. If the wear cup (D, Figure 5-3) is also worn, replace it. Use a 1/2" socket wrench to remove the screw (E, Figure 5-

3) and washer (F). Install the new wear cup and reinstall the washer and screw. Tighten the screw securely.

INSPECTING/REPLACING DRIVE BELT

The drive belt should not require inspection for many hours of operation. If replacement becomes necessary, follow the instructions given here.

Belt Inspection

1. Stop the engine and let all moving

parts stop. Disconnect spark plug wire and move it away from spark plug. Allow engine to cool. Remove the key on electric start models.

2. For convenience, we recommend that you place the unit on a raised platform to make access to the underside of the deck as easy as possible.

3. Examine the belt. Feed it around the rear (engine) pulley so the entire belt can be examined. If cracks or other damage are noted, a new belt is needed.

Belt Removal

1. Stop the engine and wait for engine to

cool. Disconnect the spark plug wire and move it away from the spark plug. Remove the ignition key on electric start models.

2. Remove gasoline from fuel tank.

3. Carefully tip unit on its left side and

secure it in place.

4. Remove the plastic plug (A, Figure 5-

6. Thread nut (B, Figure 5-4) a few turns

back onto spindle shaft (E) to protect the threads on the spindle shaft during the next step.

7. Loosen the spindle shaft by placing a wood block against the top of the nut (B, Figure 5-4) and firmly striking the wood block with a hammer.

8. Remove the nut from the spindle shaft and then remove the spindle shaft (E, Figure 5-5) and entire spindle head assembly (F) from the bottom of the deck. Slip the belt off the spindle head pulley (P).

9. Disconnect the idler arm spring (R, Figure 5-6) from the hole in the idler arm (T).

10. Using a 1/2" wrench, loosen the idler arm mounting screw (S, Figure 5-6) two full turns.

11. Using a 9/16" wrench and a 7/32" hex (Allen) wrench, loosen the mounting nut (G, Figure 5-6) and screw on the idler pulley (I) a few turns, or until belt is free to slip out between pulley and belt guide (J). Remove belt.

12. Loosen rear belt guide screw (K, Figure 5-6) enough to allow belt to be removed from engine pulley (L). Remove belt from unit.

Belt Replacement

1. Install belt on engine pulley (L, Figure

5-6) and retighten rear belt guide screw (K) securely.

2. Route belt between idler pulley (I, Figure 5-6) and belt guide (J), to inside of brake arm (M), and next to die-cast belt guides (N).

3. Securely tighten the mounting nut (G, Figure 5-6) and screw in the idler pulley (I).

4. Securely tighten the idler arm mounting screw (S, Figure 5-6). After tightening, check that idler arm is free to rotate. If not, remove idler arm and check for debris that may be interfering with freedom of movement.

5. Look at the spindle head mounting hole (O, Figure 5-6) and note the grooves that are cut into the inner sides of the hole. These grooves were formed by the splines on the spindle shaft (E, Figure 5-5).

6. Install the belt on the spindle head pulley (P, Figure 5-5) and insert the spindle shaft (E) (with attached spindle head assembly) into the spindle head mounting hole (O, Figure 5-6). Rotate the spindle head assembly to align the splines on the spindle shaft with the grooves in the mounting hole. Check that the belt is still in the pulley groove and is to the inside of the die-cast belt guides (N, Figure 5-6).

7. Using a firm push on the spindle head assembly (Figure 5-6A), seat the spindle head assembly into the hole. Check that the threaded end of the spindle shaft is protruding through the bottom of the hole.

8. Reinstall the flat washer (D, Figure 5-

4), belleville washer (C) and nut (B) on the spindle shaft. Note that the dished-in side of the belleville washer must face the flat washer. Tighten the nut securely (torque to 50 ft./lbs.), while checking frequently to ensure that the spindle head rotates freely. If the spindle head binds, it could be due to the belt being pinched between the spindle head and the belt guides. If so, remove the spindle head assembly and repeat steps 5-7.

9. Replace plastic plug (A, Figure 5-4).

TRIMMER/MOWER CLEANING AND DEBRIS REMOVAL

Thorough and regular cleaning of debris from the engine and the machine is required for maximum efficiency and good overall performance. Inspect and clean the following areas regularly, making sure the engine is stopped, and cool, before proceeding:

• Brush and wipe off all engine surfaces, especially before checking oil or adding fuel. Do not let debris, oil or grease accumulate. To access the front of the engine, lift the debris shield up and tilt it forward.

• Wipe the deck clean, particularly near the engine muffler.

• Clean the underside of the deck.

• Keep safety and operating decals clean

and legible.

• Keep all operating control levers debris-free so they work properly.

CLEANING THE ENGINE

Before each use of the machine and at each refueling, clean grass, chaff or accumulated debris from the finger guard area on top of the engine (see Figure 5-7), and from the linkage, springs and controls on the engine. Keep the area around and behind the muffler free of any combustible debris. See “Cleaning Debris” in the engine manual for complete cleaning instructions. Do not use water to clean engine parts as water could contaminate the fuel system. Use a brush or dry cloth. Be sure engine is cool before cleaning around muffler area.

NOTE: The separate engine air cleaner must also be serviced according to the instructions in the engine manual.

LUBRICATION

Applying light oil or a silicone-based lubricant to your machine allows parts to work more smoothly and protects them from the elements. Use Silicone-base Spray Lubricant (or light oil) to lubricate the following parts:

• Throttle control cable

• Control bail cable

• Nuts, bolts and other hardware

NOTE: The spindle head is permanently lubricated at the factory. There is no need for additional lubrication.

COMPACT STORAGE

For compact storage of the unit, remove the two screws and locknuts securing the handlebar and carefully (to avoid kinking the cables) rotate the handlebar so that the upper portion rests on the engine and the handlebar legs face to the rear of the unit.

GENERAL ENGINE MAINTENANCE

Perform the following engine maintenance for your engine according to the engine maintenance schedule and instructions in the separate engine manual:

Engine Oil Service

Check the engine oil level before starting the engine each day and check it after each 5 hours of continuous operation. Running the engine when it is low on oil will quickly ruin the engine.

Change the oil after every 25 hours of operation and even sooner when operating in extremely dirty or dusty conditions.

Air Cleaner Service

Operating the engine with a dirty, clogged air filter can cause poor performance and damage to the engine. Inspect and service the air cleaner after every 25 operating hours, more often if operating in very dusty or dirty conditions. Never operate the engine without the air cleaner installed.

Figure 5-6A

Figure 5-7

Engine parts must be kept clean to reduce the risk of overheating and ignition of accumulated debris. This is especially important if cutting tall grass. Clean accumulated debris at each refueling and before each use of machine.

Failure to comply can cause injury or property damage.

WARNING

Finger Guard

WARNING

14 Section 5: Maintenance

Failure to follow these instructions can result in serious personal injury or property damage.

Spark Plug Service

Inspect and clean or replace the spark plug after every 100 operating hours or annually.

Spark Arrester Screen Service

If the engine is equipped with a spark arrester screen, remove and clean it according to the time intervals and instructions in the engine manual.

Engine Cleaning

The engine must be kept clean to assure smooth operation and to reduce the risk of overheating and ignition of accumulated debris.

Carburetor/Governor Control Adjustments

The carburetor was adjusted at the factory for best operating speed. Refer to the engine manual for any adjustment information.

The governor controls the maximum safe operating speed and protects the engine and other moving parts from damage caused by overspeeding. Do not tamper with the governor settings. Seek authorized service if you think an adjustment is required.

Throttle Control Adjustment

If the engine does not shut off when the throttle lever is moved to the stop position, or if the engine does not respond to various throttle settings, refer to the engine manual for service information.

OFF-SEASON STORAGE

When storing the unit for extended periods, follow these procedures to ensure that the unit will be in good condition for future use.

• Store machine on a level surface.

• Inspect for any loose, broken or miss-

ing parts. Repair or replace parts as necessary.

• Perform recommended engine maintenance by following the engine storage instructions found in the engine manual. Be sure to protect the fuel lines, carburetor and fuel tank from gum deposits by removing fuel or by treating fuel with a fuel stabilizer (follow the engine manufacturer’s recommendations).

• Clean any dirt, grass or chaff from the air cooling system intake area and other parts of the engine.

• Disconnect spark plug wire and move away from spark plug.

• Never perform maintenance when engine is running or spark plug wire is connected, except when instructed to do so.

• Never store mower with fuel in fuel tank inside a building where fumes can reach an open flame or spark, or where ignition sources are present such as hot water and space heaters, furnaces, clothes dryers, stoves, electric motors, etc. Make sure engine is cool before storing.

• Drain gasoline outdoors into an approved container.Do not smoke and keep fuel away from open flame.

Failure to follow these instructions will result in serious personal injury or property damage.

WARNING

Section 5: Maintenance 15

Failure to follow these instructions can result in serious personal injury or property damage.

CHANGING TRIMMER LINES

When trimmer lines wear, it takes longer to complete mowing and trimming projects. A good rule of thumb is to change the lines when they reach half their original length.

Use the extra-heavy duty (.155" diameter) line when cutting thick, tough growth. Use the thinner (.130" diameter) line for less demanding conditions and for use near trees or shrubs to help prevent girdling (cutting of bark).

To Change Trimmer Lines:

1. Stop engine, allow all parts to stop

moving and then disconnect the spark plug wire. Remove the ignition key on electric start models. DO NOT touch the metal wear cup on the bottom of the spindle head—it may be hot.

NOTE: The two line holders on the trimmer head are permanently secured. Do not attempt to remove the line holders.

2. If necessary, you may tip the unit back slightly when changing lines. However, do not tip the unit all the way back as motor oil may flow to the exhaust area and the engine may smoke for several seconds when started.

3. Three different line installation patterns are available, as shown in Figures 5-8, 5-9 and 5-10.

4. Feed the line through the loops of the line holder as shown.

• An equal amount of line should project out from each side of the line holder, creating an overall 22" wide cutting swath.

• You may offset both trimmer lines somewhat to increase the cutting swath up to 25" wide. However, DO NOT offset the line so that the overall cutting swath is greater than 25". See Warning statement at right.

• Whether replacing one or both lines, they must both be .130" or .155" in diameter.

Figure 5-8: Use this single line, easy-loop pattern for all but the more difficult cutting conditions.

Offsetting the trimmer lines causes the lines to rotate faster than when they project an equal length on each side. This increases the chance of loose materials being dislodged and propelled at high speeds.

Failure of the operator to wear safety goggles and appropriate clothing and to keep bystanders away can result in severe personal injury or property damage.

WARNING

Figure 5-9: If lines tend to loosen (especially in more difficult cutting conditions), add a single reverse loop and then readjust line so that ends are even. This pattern results in a slightly narrower cutting swath.

Figure 5-10: For more difficult cutting conditions, use two of the thicker (.155" diameter) lines in each line holder. Follow the pattern shown in Figure 5-8.
