How to Use Your Trimmer

ENGINE SPEED

The engine speed is controlled by a throttle located on the side of the upper handle. Fast position is for starting and normal trimming. Slow is for light trimming and fuel economy. Stop is for stopping the engine.

[Diagram: Illustrates the throttle control mechanism with a lever and a stop position.]

TRIMMER HEAD DRIVE CONTROL

Your trimmer is equipped with a trimmer head drive control bar which will require the operator to be positioned behind the trimmer handle to operate the trimmer.

TO ADJUST TRIMMING HEIGHT

CAUTION: Stop the engine and wait for all moving parts to stop. Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with plug.

The height of cut can be set to six (6) different positions ranging from 1-1/2 inches to 3 inches. Recommended cutting height for the average yard is 2 inches.

  1. To adjust trimming height, push in the locking plate tab and move trimmer head up or down to desired position.
  2. Release tab and be sure head is locked into one of the six (6) height positions.

[Diagram: Shows the adjustable trimmer head with labels for Adjustable Trimmer Head, Locking Plate Tab.]

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 20 oz. container of oil with the unit. Slowly pour 3/4 (15 oz.) of the oil from the container down the oil fill spout into the engine.
  4. Wait one minute to allow oil to settle. Insert and tighten dipstick, then remove it to check oil level.
  5. Continue adding small amounts of oil and rechecking the dipstick until it reads full. DO NOT overfill, or engine will smoke on startup.
  6. Always be sure to retighten oil dipstick before starting engine.
  7. Check oil level before each use. Add oil if needed. Fill to full line on dipstick.
  8. Change the oil after every 25 hours of operation or each season. You may need to change the oil more often under dusty, dirty conditions.

[Diagram: Shows the engine oil cap.]

ADD GASOLINE

WARNING: Experience indicates that alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation 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 Instructions for additional information. Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.

CAUTION: Fill to bottom of gas tank filler neck. Do not overfill. Wipe off any spilled oil or fuel. Do not store, spill or use gasoline near an open flame.

[Diagram: Shows the gasoline filler cap.]

TO START ENGINE

  1. To start a cold engine, push primer three (3) times before trying to start. Use a firm push. This step is not usually necessary when starting an engine which has already run for a few minutes.
  2. Move throttle control lever to fast position.
  3. Hold upper handle firmly and pull starter handle quickly. Do not allow starter rope to snap back.

TO STOP ENGINE

NOTE: In cooler weather it may be necessary to repeat priming steps. In warmer weather overpriming may cause flooding and engine will not start. If you do flood engine, wait a few minutes before attempting to start and do not repeat priming steps.

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.

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 Owner's Manual.

IMPORTANT: Do not oil or grease plastic wheel bearings. Viscous lubricants will attract 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 graphite type lubricant sparingly.

PRODUCT SPECIFICATIONS

The model and serial numbers will be found on a decal attached to the rear of the trimmer. Record both serial number and date of purchase in space provided above.

TRIMMER

Always observe safety rules when performing any maintenance.

TIRES

TRIMMER LINE

For best results, replace trimmer lines when they have worn to half their original length. 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 than 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 dangerous missile that can cause serious injury.

TO REPLACE TRIMMER LINE

  1. Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with spark plug.
  2. Remove worn trimmer line from line carrier plate.
  3. Fold new, cut to length, trimmer line in half and insert folded end through carrier plate opening to back side of retainer clip.
  4. With folded end of line at back side of retainer clip, pull line outward until line is fully seated under the retainer clip.
  5. Repeat on other side of carrier plate.
  6. Check all lines to be sure they are the same length.
  7. Reconnect spark plug wire to spark plug.

[Diagram: Shows the trimmer head with line replacement steps, labeling Line, Carrier plate opening, Retainer clip.]

ENGINE LUBRICATION

Use only high quality detergent oil rated with API service classification SF-SJ. Select the oil's SAE viscosity grade according to your expected operating temperature.

[Diagram: Shows a temperature chart for SAE viscosity grades.]

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible engine damage from running low on oil.

Change the oil after every 25 hours of operation or at least once a year if the unit is not used for 25 hours in one year. Check the crankcase oil level before starting the engine and after each five (5) hours of continuous use. Tighten oil plug securely each time you check the oil level.

TO CHANGE ENGINE OIL

NOTE: Before tipping trimmer to drain oil, drain fuel tank by running engine until fuel tank is empty.

  1. Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with spark plug.
  2. Remove engine oil cap; lay aside on a clean surface.
  3. Tip trimmer on its side as shown and drain oil into a suitable container. Rock trimmer back and forth to remove any oil trapped inside of engine.
  4. Wipe off any spilled oil from trimmer and side of engine.
  5. Fill engine with oil (See "ADD OIL" in the Operation section of this manual).
  6. Replace engine oil cap.
  7. Reconnect spark plug wire to spark plug.

[Diagram: Shows the engine oil cap and container.]

AIR FILTER

Your engine will not run properly and may be damaged by using a dirty air filter. Replace the air filter every 100 hours of operation or every season, whichever occurs first. Service air cleaner more often under dusty conditions. Do not wash air filter.

TO CHANGE AIR FILTER

  1. Remove the air filter by turning clockwise to the stop and pull away from collar.
  2. Remove filter from inside of cover.
  3. Clean the inside of the cover and the collar to remove any dirt accumulation.
  4. Insert new filter into cover.
  5. Put air filter cover and filter into collar aligning the tab with the slot.
  6. Push in on cover and turn counter-clockwise to tighten.

[Diagram: Shows the air filter components with labels for Collar, Clip, Air filter, Air filter cover, Tab, Slot, and arrows indicating direction of removal and tightening.]

MUFFLER

Inspect and replace corroded muffler as it could create a fire hazard and/or damage.

SPARK PLUG

Replace spark plugs at the beginning of each mowing season or after every 100 hours of operation, whichever occurs first. Spark plug type and gap setting are shown in "PRODUCT SPECIFICATIONS" in Maintenance section of this manual.

CLEANING

IMPORTANT: For best performance, keep trimmer free of built-up grass and trash. Clean the underside of your trimmer after each use.

CAUTION: Disconnect spark plug wire from spark plug and place wire where it cannot come in contact with the spark plug.

CLEAN UNDER ENGINE COVER

Clean under engine cover before each use, or more frequently in heavy cutting or dirty conditions. Engine cover screen and engine air intake screen must be kept free of dirt and chaff to prevent engine damage from overheating.

ENGINE SPEED

Your engine speed has been factory set. Do not attempt to increase engine speed or it may result in personal injury. If you believe that the engine is running too fast or too slow, take your unit to a Sears or other qualified service center for repair and/or adjustment.

CARBURETOR

Your carburetor has a nonadjustable fixed main jet for mixture control. If your engine does not operate properly due to suspected carburetor problems, take your unit to a Sears or other qualified service center for repair and/or adjustment.

IMPORTANT: Never tamper with the engine governor, which is factory set for proper engine speed. Overspeeding the engine above the factory high speed setting can be dangerous. If you think the engine-governed high speed needs adjusting, take your unit to a Sears or other qualified service center, which has proper equipment and experience to make any necessary adjustments.
