OPERATING TIPS

• Assure the unit is not directed at anybody or any loose debris before starting the unit.

MAINTENANCE AND REPAIR INSTRUCTIONS

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:

• Always hold the unit securely when operating. Keep a firm grip on the handle.

• To reduce the risk of hearing loss associated with sound level(s), hearing protection is required.

• Operate power equipment only at reasonable hours— not early in the morning or late at night when people might 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, limit the number of pieces of equipment used at any one time.

• To reduce noise levels, operate power blowers at the lowest possible speed to do the job.

• Check your equipment before operation, especially the muffler, air intakes and air filters.

• Use rakes and brooms to loosen debris before blowing.

• In dusty conditions, slightly dampen surfaces when water is available.

• Watch out for children, pets, open windows or freshly washed cars, and blow debris safely away.

• Clean up after using blowers and other equipment. Dispose of debris appropriately.

	the unit to operate it as shown in figure 14 to keep from blocking the
	air intake.
	Use the blower for trees, shrubs, flower beds and hard-to-clean areas. Also use the
	unit around buildings, walls, overhangs, fences and screens, and for other normal
	cleaning procedures. Conserve water by using power blowers instead of hoses for	Fig. 14
	many lawn and garden applications, including areas such as gutters, screens, patios,	Fig. 14

	grills, porches and gardens.

Hold the blower with the right hand. Do not stand on the right side of the blower when operating the unit (Fig. 14). If you do, you will be blocking the air intake and this will affect the unit’s performance. Instead, be sure to stand on the left side of the unit to maximize the unit’s efficiency (Fig. 14).

Sweep from side to side with the nozzle several inches above the ground or floor. Slowly advance the unit, keeping the accumulated pile of debris in front of you.

Most dry blowing operations are better suited to low speeds, rather than high. High speed blowing is a better way to move heavier items like large debris or gravel.

OPERATING THE UNIT AS A VACUUM

	WARNING: To avoid serious personal injury, never unzip the
	vacuum bag without stopping the unit first.
	WARNING: As a vacuum, the unit is designed to pick up dry
	material such as leaves, grass, small twigs and bits of paper. To avoid
	serious personal injury, do not attempt to vacuum wet debris and/or	Fig. 15
	standing water as this may result in damage to the blower/ vacuum.	Fig. 15

	To avoid severe damage to the impeller, do not vacuum metal, broken
	glass or similar items.
	WARNING: Avoid situations that could catch the vacuum bag on
	fire. Do not operate near an open flame. Do not vacuum warm ash
	from fireplaces, barbecue pits, brush piles, etc. Do not vacuum
	discarded cigars or cigarettes unless the cinders are completely cool.

Use the unit for vacuuming up light debris like leaves and paper.
Be sure the vacuum bag is zipped closed before operating the unit.	Fig. 16

Place the shoulder harness over your head and onto your shoulder. Hold the vacuum with both on hands on the handle (Fig. 15), tilting the suction tube slightly, and use a sweeping action to collect light debris (Fig. 16). The debris will flow into the vacuum bag. Things such as small leaves and small twigs will be mulched as they pass through the fan housing, allowing the vacuum bag to hold more debris.

Emptying the Vacuum Bag

When the bag is full, suction will noticeably decrease. Turn off the unit and allow the impeller to stop before you unzip the bag.

1.While wearing eye protection and a dust mask, unzip the vacuum bag and empty the contents into a garbage bag or container.

2.Turn the bag inside out after initial emptying and vigorously shake out dust and debris.

3.Zip close and reinstall the vacuum bag.

NOTE: Empty the bag after each use to avoid deterioration and obstructing air flow, which will reduce the performance of the vacuum.

MAINTENANCE AND REPAIR INSTRUCTIONS

WARNING: To prevent serious injury, never perform maintenance or repairs with unit running. Always service and repair a cool unit. Disconnect the spark plug wire to ensure that the unit cannot start.

MAINTENANCE SCHEDULE

Perform these required maintenance procedures at the frequency stated in the table. These procedures should also be a part of any seasonal tune-up.

NOTE: Some maintenance procedures may require special tools or skills. If you are unsure about these procedures, take your unit to a Troy-Bilt or other qualified service dealer.

NOTE: Maintenance, replacement, or repair of the emission control devices and system may be performed by a Troy- Bilt or other qualified service dealer.
