This engine is certified to operate on unleaded gasoline with a pump octane rating of 93 or higher. You may use regular unleaded gasoline containing no more than 10% ethanol (E10) or 5% methanol by volume.

In addition, methanol must contain cosolvents and

corrosion inhibitors. Use of fuels with content of ethanol or methanol greater than shown above may cause starting

and/or performance problems. It may also damage metal, rubber, and plastic parts of the fuel system. Engine

damage or performance problems that result from using a fuel with percentages of ethanol or methanol greater than shown above are not covered by warranty.

Check the fuel level by looking through the translucent fuel tank. If the fuel level is low, refuel in a well-ventilate d area with the engine stopped. If the engine has been

running, allow it to cool first.

Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid getting dirt or water in the fuel tank.

To refuel, rest the trimmer on the ground with the fuel tank cap facing up, as shown. Remove the fuel tank cap

and fill the tank with gasoline to the bottom of the filler neck. Refuel carefully to avoid spilling fuel. Do not overfill. There should be no fuel in the filler neck.

After refueling, tighten the fuel tank cap securely.

Never refuel the engine inside a building where gasoline fumes may reach flames or sparks. Keep gasoline away

from appliance pilot lights, barbecues, electric appliances, power tools, etc. Spilled fuel is not only a fire hazard, it causes

environmental damage. Wipe up spills immediately. Move at least 10 feet (3 meters) away from the fueling source and site before starting the engine.

Fuel can damage paint and plastic. Be careful not to spill fuel when filling your fuel tank. Damage caused by spilled fuel is not covered under warranty.

The trimmer is shipped WITHOUT OIL in the engine. NOTE:Fill oil before starting engine.

Running the engine with too little or too much oil can cause engine damage.

Check the engine oil level before each use, or every 10 hours if operated continuously. Rest the trimmer on a level surface, with the engine stopped and in an upright position.

NOTE:

• Engine Oil Level Check

1. Place the trimmer on a level surface, and then remove the oil filler cap/dipstick.

4. Screw in the oil filler cap/dipstick securely.

Running the engine with too little or too much oil can cause engine damage.

NOTE:

4. Screw in the oil filler cap/dipstick securely.

2. Slowly add the recommended oil (included in the box) to the bottom edge of the oil filler opening. Do not overfill, as the engine oil tank capacity is small.

3. If the supplied oil is not used, add enough SAE 10W-

30 API service category SJ or later oil. Add oil until

the oil level is to the bottom edge of the oil filler opening.

1. Remove the filler cap/dipstick and wipe it clean.

2. Insert and remove the dipstick without screwing it into the filler opening. Check the oil level shown on the dipstick.

3. If the oil level is low, fill to the edge of the oil filler hole with the recommended oil . To avoid overfilling or underfilling, be sure the engine is in a level position, as shown.

ENGINE OIL

Drain the used oil while the engine is warm. Warm oil drains quickly and completely.

• Engine Oil Change

• Engine Oil Recommendations

1. Place a suitable container below the engine to catch the used oil, then remove the filler cap/dipstick and drain the used oil through the filler opening. Allow the used oil to drain completely.

Please dispose of used motor oil in a manner that is

compatible with the environment. We suggest you take used oil in a sealed container to your local recycling center or service station for reclamation. Do not throw it in the trash, pour it on the ground, or pour it down a drain.

2. With the engine in an upright position, fill to the edge of the oil filler hole with the recommended oil.

3. Screw in the filler cap/dipstick securely.

Oil is a major factor affecting performance and service life. Use 4-stroke automotive detergent oil.

SAE 10W-30 is recommended for all temperatures within the recommended operating range for these trimmers. The recommended operating range extends from 23° ~ 104°F (-5° ~ 40°C).

The SAE oil viscosity and service classification are on the API label on the oil container. Recommend that you use API service category SJ or later.

NOTE: change the engine oil after first month or 10 hours. NOTE: change the engine oil every 6 months or 50 hours.

When properly equipped with a cutting attachment guard and cutting head, your unit will trim unsightly weeds and tall grass in those hard-to-reach areas - along fences, walls,foundations and around trees.It can also be used for scalping to remove vegetation downto the ground for easier preparationofagarden or to cleanoutaparti NOTE: Evenwith care, trimming around foundations, brick or stone walls, curves, etc., will result in above normal string wear.

TRIMMING / MOWING

Swing trimmer withasickle-like motion from side to side. Do not tilt the cutting head during the procedure. Test area to be trimmed for proper cutting height. Keep cutting head at same level for even depth of cut (Fig. 12A).

cular area.

CLOSERTRIMMING

Position trimmer straight ahead with a slight tilt so bottom of cutting head is above ground level and string contact occurs at proper cutting point. Always cut away from operator.Do not pull trimmer toward operator.

FENCE/FOUNDATION TRIMMING

Approach trimming around chain link fences, picket fences, rock walls and foundations slowly to cut close without whipping string against the barrier. If the string comes in contact with rock, brick walls, or foundations, it will break or fray.If string snags fencing, it will snap off.

TRIMMING AROUND TREES

Trim around tree trunks withaslow approach so string does not contact bark.Walk around the tree trimming from left to right. Approach grass or weeds with the tip of the string and tilt cutting head slightly forward.

WARNING: Use extreme caution when SCALPING. Keepadistance of 50 feet (15 meters) between operator, other people and animals during these operations.

SCALPING

Scalping refers to removal of all vegetation down to the ground. To do this, tilt the cutting head to about a 30 degree angle to the right. By adjusting the handle you will have better control during this operation. Do not attempt this procedure if there is any chance flying debris could injure operator, other people or cause damage to property (Fig. 12B).

• CUTTING WITH BLADES

WARNING:Beforeoperatingthis machinewith

a bladecheck to ensure it is properlyinstalled. Follow all warnings listed in the blade safety precautions section in this manual.

Always wear eye protection and protective clothing when cutting withablade. Always use the harness for blade operations.

• USING WEED BLADES

SCYTHING WEEDS

Scything refers to cutting by moving the blade from side to side inalevel arc. It is most effective with grassy weeds and light undergrowth. It should not be used to cut tough weeds or woody growth (Fig. 13).

Fig. 13

CAUTION: Do not use weed blades to cut brush or tree saplings.

• USING A BRUSH BLADE

SCYTHING

Scything may be used with a brush blade for light brush and undergrowth.It is not recommended for tough growth.

BINDING

Top heavy growth such as saplings and heavy brush can bind and stop the blade. Avoid binding by anticipating which way the growth will lean, and cut from the opposite side. If the blade binds in a cut stop the engine immediately. Hold the unit up to prevent the blade from cracking or breaking while pushing the sapling away from the cut to free the blade.

AVOID KICKOUT

Kickout is the reaction ofamoving blade if it contacts a strong tree, brush orasolid object.The force that occurs violently pushes the blade away in an arc. Kickout could cause loss of control resulting in injury to the operator or bystanders.

DO NOT USEABLADE NEAR A CHAIN LINK FENCE, METAL STAKES, LANDSCAPE BORDERS OR BUILDING FOUN

The Partner kickout by providing stops to brace the unit against the object being cut. Place the sapling against the stop (A) so the rotation of the blade continually draws it into the stop (A) (Fig. 14).
