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.

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.

FENCE/FOUNDATIONTRIMMING

Approach tr imming around chain link fences, picket fences, rock walls and foundations slowly to cut close without whipping string against the barrier.If the string comes incontact with rock,brick walls, orfoundations, it will breakor fray.If stringsnags fencing,it will snapoff.

TRIMMING AROUNDTREES

Trim aroundtree trunks withaslow approach so string doesnot contactbark. Walkaround thetree trimmingfrom left toright. Approach grass orweeds with the tipof the string andtilt cuttinghead slightly forward.

SCALPING

Scalping refers toremoval of all vegetationdown to the ground. To do this, tilt the cutting head to about a 30 degree angleto theright. Byadjusting the handleyou will have bettercontrol during this operation.Do not attempt this procedure ifthere is any chanceflying debris could injure operator,other peopleor cause damageto property (Fig.12B).

DO NOTSWEEP WITHTRIMMER

Sweeping refers to tilting cutting head to sweep away debris fromwalkways, etc.Yourtrimmer i

sapowerful tool and smallstones or other suchdebris may behurled 50 feet (15 meters) or more, causing injury or damage to nearby property such as automobiles, homes and windows.

• CUTTING WITH BLADES

Always weareye protectionand protective clothingwhen cutting withablade. Alwaysuse the harnessfor bladeoperations.

• USING WEED BLADES

SCYTHINGWEEDS

Scythingrefers tocutting bymoving theblade fromside to side inalevelarc. It ismost effective withgrassy weeds and lightundergrowth. Itshould not beused to cut

large,

tough weedsor woodygrowth (Fig.13).

• USING A BRUSHBLADE

SCYTHING

Scything maybe used with abrush blade forlight brush andundergrowth. Itis notrecommended fortough growth.

BINDING

Topheavy growth suchas saplings andheavy brushcan bind and stop the blade. Avoid binding by anticipating which waythe growthwill lean,and cut fromthe opposite side. If the bladebinds in a cut stop theengine immediately. Hold the unit up to preventthe blade from cracking or breaking whilepushing the sapling awayfrom the cut to free theblade.

AVOIDKICKOUT

Kickout isthe reaction ofamoving bladeif it contacts a strong tree,brush orasolid object.The forcethat occurs violently pushesthe blade away inan arc. Kickoutcould cause lossof control resultingin injury tothe operator or bystanders. DO NOTUSEABLADE NEAR A CHAINLINK FENCE, METAL STAKES, LANDSCAPE BORDERS OR BUILDING FOUN

DATIONS.

The Partner

blade guardis designed to reduce therisk of kickout by providing stopsto brace the unit against the object beingcut. Place the saplingagainst the stop (A)so the rotation of the bladecontinually drawsit intothe stop (A)(Fig. 14).

WARNING: Use extreme caution when SCALPING. Keepadistanceof 50 feet (15 meters) betweenoperator, other peopleand animals duringthese operations.
