5. While holding the Allen wrench in the spindle hole, tighten the nut by turning the wrench clockwise until tight (Fig. 11).

NOTE: Make sure that the blade stays flat and centered against the output shaft throughout installation. CHECKING THE OIL LEVEL

The importance of checking and maintaining the proper oil level in the crankcase cannot be

veremphasized. Check oil before each use:

1. Stop the engine and allow oil to drain into the crankcase.

. Place unit on a flat, level surface.

. Keep dirt, grass clippings and other debris out

f the engine. Clean the area around the

ipstick before removing it.

4. Remove the oil fill plug.

. Look into the oil fill hole, use a flashlight if needed. The oil should be just touching the inner most thread (Fig. 13).

. If the oil level is not touching the inner most thread on the oil fill hole, add a small amount of oil to the oil fill hole

nd recheck (Fig. 16). Repeat this procedure until the oil level reaches the inner most thread on the oil fill hole.

OTE: Do not overfill the unit.

IR FILTER MAINTENANCE leaning the Air Filter

lean and re-oil the air filter per the maintenance schedule. It is an important item to

aintain. Failure to maintain the air filter properly can result in poor performance or

cover out (Fig. 18).

EPLACING THE SPARK PLUG

Use a replacement Champion® #RDZ4H spark plug. The correct air gap is 0.025 in. (0.635 mm). Remove the plug

nd check its condition per the maintenance schedule.

. Stop the engine and allow it to cool. Remove the six (6) screws on the back of the engine cover with a Flat-head or

-25 screwdriver (Fig. 20).

. Grasp the plug wire firmly and pull the cap from the spark plug.

. Clean dirt from around the spark plug. Remove the spark plug from the cylinder head by turning a 5/8 in. socket

ounterclockwise.

WARNING:

electrodes. Grit in the engine could damage the cylinder.

4. Replace cracked, fouled or dirty spark plug. Set the air gap at 0.025 in. (0.635 mm) using a feeler gauge (Fig. 24).

5. Install a correctly-gapped spark plug in the cylinder head. Turn the 5/8 in. socket

lockwise until snug.

If using a torque wrench torque to: 110-120 in.•lb. (12.3-13.5 N•m)

Do not sand blast, scrape or clean spark plug

. Drain all gasoline from the gas tank into a container. Do not use gas that has been stored for more than 30 days.

ispose of the old gasoline in accordance to federal, state and local regulations.

. Start the engine and allow it to run until it stalls. This ensures that all gasoline has been drained from the carburetor.

. Allow the engine to cool. Remove the spark plug and put 5 drops of high quality motor oil into the cylinder. Pull the

tarter rope slowly to distribute the oil. Reinstall the spark plug.

OTE: Remove the spark plug and drain all of the oil from the cylinder before attempting to start the edger after storage.

. Change the oil, referring to Changing the Oil. Dispose of the old oil in accordance to federal, state and local

regulations.

5. Thoroughly clean the unit and inspect for any loose or damaged parts. Repair or replace damaged parts and tighten loose screws, nuts or bolts. The unit is ready for storage.

o avoid serious personal injury, always turn the unit off and allow it to cool before

OPTIONAL ACCESSORY

ELECTRIC STARTER AND POWER START BIT™ FEATURES

This unit can be started with an optional Electric Starter or Power Start Bit™ (Items Sold Separately!). If choosing to

tart the unit using one of these features or have questions, please contact your local retailer or call 1-800-828-5500 in

he U.S. (1-800-668-1238 in Canada) for more information and purchasing. You may also go to www.troybilt.com or

www.troybilt.ca.

DLE SPEED ADJUSTMENT

WARNING:

ear protective clothing and observe all safety instructions to prevent

erious personal injury.

he idle speed of the engine is adjustable. An idle adjustment screw is between the

T air filter cover and the engine starter housing (Fig. 19).

NOTE: Careless adjustments can seriously damage your unit. An authorized

service dealer should make carburetor adjustments.

The blade may spin during idle speed adjustments.

dle Adjustment Screw

Fig. 19

If, after checking the fuel and cleaning the air filter, the engine still will not idle, adjust the idle speed screw as follows:

1. Start the engine and let it run at a high idle for a minute to warm up. Refer to Starting and Stopping Instructions.

2. Release the throttle lever and let the engine idle. If the engine stops, insert a small Phillips in between the air filter over and the engine cover (Fig. 19). Turn the idle speed screw in, clockwise, 1/8 of a turn at a time (as needed)

ntil the engine idles smoothly.

OTE: The blade should not rotate when the engine idles.

. If the blade rotates when the engine idles, turn the idle speed screw counterclockwise 1/8 of a turn at a time (as

eeded), to reduce idle speed.

Checking the fuel, cleaning the air filter, and adjusting the idle speed should solve most engine problems. If not and all of the following are true:

• the engine will not idle

• the engine hesitates or stalls on acceleration

• there is a loss of engine power

Have the carburetor adjusted by an authorized service dealer.

ROCKER ARM CLEARANCE

This requires disassembly of the engine. If unsure or unqualified to perform this, take the unit to an authorized service center. NOTE: Inspect the valve to rocker arm clearance with a feeler gauge per the

maintenance schedule.

• The engine must be cold when checking or adjusting the valve clearance.

View of the Rear

Engine Cover

• This task should be performed inside, in a clean, dust free area.

1. Remove the six (6) screws on the back of the engine cover with a Flat-head or T-

25 Torx screwdriver (Fig. 20).

Screws

2. Disconnect the spark plug wire.

3. Clean dirt from around the spark plug. Remove the spark plug from the cylinder

head by turning a 5/8 in. socket counterclockwise.

Fig. 20

4. Remove the engine cover (Fig. 20).

5. Clean dirt from around the rocker arm cover. Remove the screw holding the rocker

arm cover with a large flat blade screwdriver or Torx T-25 bit (Fig. 21). Remove the rocker arm cover and gasket.

6. Pull the starter rope slowly to bring the piston to the top of its travel, (known as

top dead center). Check that:

• The piston is at the top of its travel. This should be done by looking into the spark plug hole. (Fig. 21)

• Both rocker arms move freely, and both valves are closed

If these statements are not true, repeat this step.

7. Slide the feeler gauge between the rocker arm and the valve return spring. Measure the clearance between the valve stem and rocker arm (Fig. 23). Measure both the intake and exhaust valves.

The recommended clearance for both intake and exhaust is .003 – .006 in. (.076 –

0.152 mm). Use a standard automotive .005 in. (0.127 mm) feeler gauge. The feeler

gauge should slide between the rocker arm and valve stem with a slight amount of resistance, without binding (Fig. 23).

8. If the clearance is not within specification:

a. Turn the adjusting nut using a 5/16 inch (8 mm) wrench or nut driver (Fig. 23).

• To increase clearance, turn the adjusting nut counterclockwise.

• To decrease clearance, turn the adjusting nut clockwise. b. Recheck both clearances, and adjust as necessary.

9. Reinstall the rocker arm cover using a new gasket. Torque the screw to 20–30 in•lb (2.2–3.4 N•m).

10. Check the spark plug and reinstall. See Replacing the Spark Plug.
