Husqvarna HU675HWT Grass Trimmer

SAFETY RULES

The operation of any trimmer can result in foreign objects thrown into the eyes, which can result in severe eye damage. Always wear safety glasses or eye shields while operating your trimmer or performing any adjustments or repairs. We recommend standard safety glasses or a wide vision safety mask worn over spectacles

WARNING: In order to prevent accidental starting when setting up, transporting, adjusting or making repairs, always disconnect spark plug wire and place wire where it cannot contact plug.
CAUTION: Muffler and other engine parts become extremely hot during operation and remain hot after engine has stopped. To avoid severe burns on contact, stay away from these areas.
WARNING: This trimmer is equipped with an internal combustion engine and should not be used on or near any un improved forest-covered, brush-covered or grass-covered land unless the engine’s exhaust system is equipped with a spark arrester meeting applicable local or state laws (if any). If a spark arrester is used, it should be maintained in effective working order by the operator.

In the state of California the above is required by law (Section 4442 of the California Public Resources Code). Other states may have similar laws. Federal laws apply on federal lands. A spark arrester for the muffler is available through your nearest Sears Service Centre/Department in Canada (see the REPAIR PARTS section of this manual).

GENERAL OPERATION

• Read, understand, and follow all instructions on the machine and in the manual before starting. Be thoroughly familiar with the controls and the proper use of the machine before starting.
• Do not put hands or feet near or under rotating parts.
• Keep all parts of your body away from muffler and spinning line. A hot muffler can cause serious burns.
• Only allow responsible individuals, who are familiar with the instructions, to operate the machine.
• Stay away from breakable objects, such as house windows, auto glass, greenhous es, etc.
• Clear the area of objects such as rocks, toys, wire, bones, sticks, etc., which could be picked up and thrown by the spinning lines.
• Be sure the area is clear of other people before trimming, particularly small children and pets. Stop machine if anyone enters the area.
• Wear appropriate clothing such as a longsleeved shirt or jacket. Also wear long trousers or slacks. Do not wear shorts.
• Do not wear loose clothing which could get caught in this equipment.
• Do not operate the machine when barefoot or wearing open sandals. Always wear work gloves and sturdy footwear. Leather work shoes or short boots work well for most people. These will protect the operator’s ankles and shins from small sticks, splinters, and other debris, and improve traction.
• Do not pull machine backwards unless absolutely necessary. Always look down and behind before and while moving backwards.
• Do not operate the machine without proper guards, plates or other safety protective devices in place.
• See manufacturer’s instructions for proper operation and installation of accessories. Only use accessories approved by the manufacturer.

2. Release tab and be sure head is locked into one of the six (6) height positions.

BEFORE STARTING ENGINE ADD OIL

Your trimmer is shipped without oil in the engine. For type and grade of oil to use, see “ENGINE” in the Maintenance section of this manual.

CAUTION: DO NOT overfill engine with oil, or it will smoke on startup.

1. Be sure trimmer is level and area around oil fill is clean.
2. Remove oil dipstick from oil fill spout. Make sure that rim of spout is clean.
3. You receive a container of oil with the unit. Slowly pour the entire container down the oil fill spout into the engine.
   NOTE: Initial oil fill requires only 18 oz. due to residual oil in engine from the manufacturers 100% quality testing. When changing oil you may need 20 oz.
4. Insert and tighten dipstick.

IMPORTANT:

• Check oil level before each use. Add oil if needed. Fill to full line on dipstick.

ADD GASOLINE

• Fill fuel tank to bottom of tank filler neck. Do not overfill. Use fresh, clean, regular unleaded gasoline with a minimum of 87 octane. Do not mix oil with gasoline. Purchase fuel in quantities that can be used within 30 days to assure fuel freshness.

CAUTION: Alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and for mation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. See Storage In structions for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.

CAUTION: Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame.

TO START ENGINE

NOTE: Due to protective coatings on the engine, a small amount of smoke may be present during the initial use of the product and should be considered normal.
NOTE: Your engine is equipped with an automatic choke system. No priming or choking is required before starting.

1. Move engine brake control lever to RUN position.
2. Hold upper handle firmly and pull starter handle quickly. Do not allow starter rope to snap back.

TO STOP ENGINE

• To stop engine, move engine brake control lever to the right (out of the RUN position). The engine will stop running and the lever will move to the STOP position.

TRIMMING TIPS

• If the weeds or grass are tall and thick, operate the trimmer at a slower walking speed.
• Frequently clean the underside of the trimmer to remove any grass build up. Keep top of engine around starter clear and clean of grass clippings and chaff. This will help engine air flow and extend engine life.
• For best results and longer lasting line, use the ends of the line to do the cutting. This is easily done by moving
  slowly through very thick and heavy weeds.
• Use the left side of trimmer when trimming along fences, walls, flowerbeds and other such objects.
• If trimmer lines become too short, it will take longer to complete the job. If trimmer lines are worn to less than half their original length, they should be replaced. See “TO REPLACE TRIMMER LINE” in the Maintenance section of this manual.
• Trimmer head contact with concrete, asphalt or other hard surfaces may cause premature wear of the ball on bottom of trimmer head.

MAINTENANCE

GENERAL RECOMMENDATIONS

The warranty on this trimmer does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, operator must maintain trimmer as instructed in this manual. Some adjustments will need to be made periodically to properly maintain your unit. All adjustments in the Service and Adjustments section of this manual should be checked at least once each season.

• Once a year, replace the spark plug and replace air filter element. A new spark plug and clean/new air filter element assure proper air-fuel mix ture and help your engine run better and last longer.
• Follow the maintenance schedule in this manual.

BEFORE EACH USE

1. Check engine oil level.
2. Check for loose fasteners.
3. Clean under engine cover.

LUBRICATION

To prolong the useful life of your trimmer, change engine oil as recommended in this section of Operator’s Manual.
IMPORTANT: Do not oil or grease plastic wheel bearings. Vis cous lu bri cants will at tract dust and dirt that will shorten the life of the self-lubricating bearings. If you feel they must be lubricated, use only a dry, powdered graph ite type lubricant sparingly

TRIMMER

Always observe safety rules when performing any maintenance.

TIRES

• Keep tires free of gasoline, oil, or insect control chemicals which can harm rubber.
• Avoid stumps, stones, deep ruts, sharp objects and other hazards that may cause tire damage

TRIMMER LINE

For best results, replace trimmer lines when they have worn to half their original length.

20″ models use .130 inch diameter trimmer line. Cut new trimmer line length to 16-3/4 inches. 22″ models use .155 inch diameter trimmer line. Cut new trimmer line length to 18-3/4 inches

After new line is installed on trimmer head, check all lines so they do not vary more then one (1) inch in length. This is important to make sure the trimmer head is balanced and will not vibrate abnormally.
WARNING: Use only the specified trimmer line. Do not use other materials such as wire, string, rope, etc. Wire can
break off during trimming and become a danger ous missile that can cause serious injury.

TO CUT LINE TO PROPER LENGTH
NOTE: Trimmer line pre-cut to proper length is available for this unit; see the Repair Parts section of this manual.
If trimmer line is purchased in bulk, it must be cut to length before using. Use the built-in length guage as follows:

1. From front of trimmer, place the end of spooled trimmer line at the mark on the side of the debris shield as shown.
2. Wrap trimmer line around front of chassis cover to other side and cut at the mark (for your unit’s width of cut)

TO REPLACE TRIMMER LINE
