MAINTENANCE AND REPAIR INSTRUCTIONS
AIR FILTER MAINTENANCE
WARNING: To avoid serious personal injury, always turn the unit off and allow it to cool before cleaning or maintaining it.
Cleaning the Air Filter
Failure to maintain the air fi lter will VOID the warranty.
1. To open the air fi lter cover, push the tab on the left side of the |
|
|
| Fig. 17 | |
cover inward and pull the air fi lter cover slightly out and to the |
| |
| ||
|
| |
right (Fig. 18). |
|
|
2. Remove the air fi lter (Fig. 18).
3. Wash the fi lter in detergent and water. Making sure to rinse the fi lter thoroughly and allow it to dry.
4. Lightly coat the fi lter with clean SAE 30 motor oil.
5. Squeeze the filter to spread and remove excess oil.
6. | Replace the filter. | Slot |
|
|
NOTE: Operating the unit without the air fi lter will VOID the |

7. | To reinstall the air fi lter cover, position the hooks on the right |
|
| Fig. 18 |
| side of the air filter cover into the slots at the right side of the |
|
|
|
| back plate (Fig. 18). |
|
|
|
8.Swing the cover to the left and press closed so the air fi lter cover tab snaps into the slot on the back plate (Fig. 18).
IDLE SPEED ADJUSTMENT
The idle speed of the engine is adjustable. An idle adjustment screw is between the air fi lter cover and the engine starter housing (Fig. 19).
• The tubes are in place and secure
OPERATING TIPS
Fig. 11
NOTE: Careless adjustments can seriously damage to the unit. A qualifi ed service dealer should make carburetor adjustments.
Using the Variable Speed Cruise Control
For longer periods of operation and to eliminate possible finger fatigue.
1. | Move the variable speed cruise control toward the |
|
|
| FAST position to incrementally increase or maintain the unit’s | Cruise |
|
| engine speed (Fig. 12). When the variable speed cruise | Control | SLOW |
| control is pressed, the trigger will recede into the handle. |
|
|
2. | To decrease engine speed, move the variable speed cruise |
|
|
| control to the SLOW position and the trigger will return to idle |
| FAST |
| (Fig. 12). |

|
| |
Other Tips |
|
| |
• | Always use a fi rm grip when holding the unit. |
|
|
• | To reduce the risk of hearing loss, hearing protection is required. |
| Fig. 12 |
•Operate power equipment only at reasonable hours
when people might not be disturbed. Comply with times listed in local ordinances. Usual recommendations are 9:00 am to 5:00 pm, Monday through Saturday.
•To reduce noise levels, operate the unit at the lowest possible speed to do the job.
•Use rakes and brooms to loosen debris before blowing.
•Watch for bystanders, open windows or cars; blow debris safely away.
•Use the curved tube extension so the unit can work closer to the ground.
•Clean up after using blowers and other equipment. Dispose of debris appropriately.

CHECKING THE OIL LEVEL
If, after checking the fuel and cleaning the air fi lter, the engine still will not idle, adjust the idle speed screw as follows:
1. Start the engine and warm up according to the Starting/ | Idle Adjustment |
Stopping Instructions. | Screw |
2. Release the trigger and let the engine idle. If the engine stops, |
|
insert a small Phillips screwdriver in between the air filter cover |
|
and the engine cover (Fig. 19). Turn the idle speed screw 1/8 |
|
of a turn clockwise at a time until the engine idles smoothly. |
|
Checking the fuel, cleaning the air fi lter, and adjusting the idle |
|
speed should solve most engine problems. If not and all of the |
|
following are true: | Fig. 19 |
|
•the engine will not idle
•the engine hesitates or stalls on acceleration
•there is a loss of engine power
take the unit to a qualifi ed service dealer.
ROCKER ARM CLEARANCE
WARNING: To avoid serious personal injury, always turn the unit off and allow it to cool before cleaning or maintaining it.
This requires disassembly of the engine. If you feel unsure or unqualifi ed to perform this, take the unit to a qualified service dealer.
• | The engine must be cold when checking or adjusting the |
|
| |
| rocker arm clearance. |
| Screws | |
• | This task should be performed inside, in a clean, dust free | Screws | ||
| ||||
| area. |
|
| |
1. | Remove the 8 engine cover screws with the appropriate tool |
|
| |
| (Fig. 20), then remove the cover. |
|
| |
NOTE: Make sure to store the screws so that they can be | Fig. 20 |
| ||
| reinstalled into their original holes. |
|
| |
2. | Disconnect the spark plug wire. | Rocker |

4. | Remove the screw holding the rocker arm cover with the |
| ||
Plug |
| |||
| appropriate tool (Fig. 21). Remove the rocker arm cover and | Hole |
| |
| gasket. |
|
| |
5. | Turn the flywheel slowly to bring the piston to the top of its |
|
| |
| travel (known as top dead center). Check that: | Fig. 21 |
| |
• The piston is at the top of its travel by looking in the spark | Adjustment Nut | Rocker Arm | ||
| plug hole (Fig. 21) | |||
• Both rocker arms move freely, and both valves are closed. |
|
| ||
If these statements are not true, repeat this step. |
|
| ||
6. Slide the feeler gauge between the rocker arm and the valve |
|
return spring. Measure the clearance between the valve stem |
|
and rocker arm (Fig. 22). Measure both the intake and exhaust |
|
valves. |
The importance of checking and maintaining the proper oil level in the crankcase cannot be overemphasized. Check oil before each use:
1.Stop the engine and allow oil to drain into the crankcase.
2.Place the engine on a level surface.
3.Clean the area around the oil plug before removing it. Keep dirt, grass clippings, and other debris out of the engine.
4.Remove the oil plug (Fig. 14).
5.Look into the oil fill hole (use a fl ashlight if needed). The oil should be just touching the innermost thread (Fig. 13).
6.If the oil level is not touching the innermost thread on the oil fill hole, add a small amount of oil to the oil fi ll hole and recheck (Fig. 13). Repeat this procedure until the oil level reaches the innermost thread on the oil fill hole.
NOTE: Do not overfi ll the unit.
NOTE: Make sure the

the rocker arm and valve stem with a slight amount of resistance, without binding (Fig. 22.)
7. If the clearance is not within specification:
a.Turn the adjusting nut using a 5/16 inch (8 mm) wrench or nut driver (Fig. 22).
•To increase clearance, turn the adjusting nut counterclockwise.
•To decrease clearance, turn the adjusting nut clockwise.
b.Recheck both clearances, and adjust as necessary.
8.Reinstall the rocker arm cover using a new gasket (Fig. 21). Torque the screw to:
9.Check the spark plug and reinstall. See Replacing the Spark Plug.
10.Reinstall the spark plug wire.
11.Reinstall the engine cover. Check alignment of the cover before tightening the screws. Tighten screws.
NOTE: Make sure that the screws are reinstalled into their original holes (Fig. 20).
REPLACING THE SPARK PLUG
Change the oil while the engine is still warm. The oil will flow freely and carry away more impurities.
1. Remove the oil fill plug.
2. Pour the oil out of the oil fi ll hole and into a container by tipping the unit to a vertical position (Fig. 15). Allow ample time for complete drainage.
3. | Wipe up any oil residue on the unit and clean up any oil that |
|
| may have spilled. Dispose of the oil according to federal, state |
|
| and local regulations. |
|
4. | Refill the crankcase with 2.03 fl .oz. (60 ml) of SAE 30 SF, SG, | Fig. 15 |
| SH oil (Fig. 17). | |
|
|
NOTE: Use the bottle and spout saved from initial use to measure the correct amount of oil. The fi ll line on the bottle’s label measures approximately 2.03 fl .oz. (60 ml) (Fig. 16).
5.Check the level. See Checking the Oil Level.
6. Once full, replace the oil plug.

WARNING: Do not sand blast, scrape or clean spark plug electrodes. Grit in the engine could damage the cylinder.
5.Replace cracked, fouled or dirty spark plug. Set the spark gap at 0.025 in. (0.635 mm) using a feeler gauge (Fig. 24).
6. | Install a |
