Warning: Lack of lubrication voids engine warranty. Gasoline and oil must be mixed at 25:1.

- Fuel Mixing Table

Gasoline Lubricant

5 Liters 200 ml (cc)

Mixing Procedure 25 Parts Gasoline to

1 part Lubricant

1ml = 1cc

RECOMMENDED FUELS

OPERATING INSTRUCTIONS

- STARTING A COLD ENGINE

NOTE: To minimize load on engine during starting and warm-up, trim excess cutter line to 5^ (13cm) (Fig. 5A).

1. Move ignition switch to the "RUN (I)" position (Fig. 5B).
2. Your unit is designed with a 3 position choke: CHOKE "F, PARTIAL " and RUN " .Move choke lever to CHOKE " F position (Fig. 5C).
3. Prime the carburetor. Pump the primer bulb (A) 10 times (Fig. 5D).
4. Grip handle firmly - depress safety trigger (B) & throttle trigger (C) to the FULL THROTTLE position (Fig. 5E).
5. Pull starter rope out a short way until resistance is felt (approximately 100mm ) (Fig. 5F). A smooth rapid pull is required for a strong spark. Pull starter rope briskly 4 times.
6. Move choke lever to PARTIAL " position (Fig. 5G).
7. Pull starter rope again 4 times while trigger is in the full throttle position (Fig. 5F)
8. Once engine starts, leave in the PARTIAL " position for 10 seconds.

Trimming Instructions

- ADDITIONAL SAFETY PRECAUTIONS

Before operating your unit, review ALL SAFETY PRECAUTIONS in this manual.

WARNING / CAUTION

• IF UNFAMILIAR WITH TRIMMING techniques, practice the procedures with ENGINE in "OFF" position.
• ALWAYS CLEAR WORK area of debris such as cans, bottles, rocks, etc. Striking objects can cause serious injury to operator or bystanders and also damage equipment. If an object is accidentally hit, immediately TURN ENGINE OFF and examine equipment. Never operate unit with damaged or defective equipment.
• ALWAYS TRIM OR CUT AT HIGH ENGINE SPEEDS. Do not run engine slowly at start or during trimming operations.
  DO NOT use equipment for purposes other than trimming or mowing weeds.
• NEVER raise stringhead above knee height during operation.
  DO NOT operate unit with other people or animals in the immediate vicinity. Allow a minimum of 50 feet (15 meters) between operator and other people and animals when trimming or mowing. Allow a distance of 100 feet (30 meters) between

GB

operator and other people and animals when SCALPING with stringhead cutter.

• IF OPERATING UNIT ON A SLOPE, stand below the cutting attachment. DO NOT OPERATE on a slope or hilly incline if there is the slightest chance of slipping or losing your footing.

STRINGHEAD LINE RELEASE

WARNING: DO NOT use steel wire or plastic-coated steel wire of any kind with your stringhead. Serious operator injury can result.

To release fresh line, run engine at full throttle and "bump" stringhead against lawn. Line will automatically release. The knife in debris shield will trim excess line (Fig. 7A).

CAUTION: Periodically remove weed wrap to prevent overheating the drive shaft. Weed wrap occurs when strands of weed become entangled around the shaft beneath the debris shield (Fig. 7B). This condition prevents the shaft from being properly cooled. Remove weed wrap with screwdriver or similar

- TRIMMING PROCEDURES

When properly equipped with a debris shield and stringhead, 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 down to the ground for easier preparation of a garden or to clean out a particular area.

NOTE: Even with care, trimming around foundations, brick or stone walls, curves, etc., will result in above normal string wear.

TRIMMING/MOWING

Swing trimmer with a sickle-like motion from side to side. Do not tilt the stringhead during the procedure. Test area to be trimmed for proper cutting height. Keep stringhead at same level for even depth of cut (Fig. 8A).

CLOSER TRIMMING

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

WARNING: Use extreme caution when

SCALPING. Keep a distance of 100 feet (30 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 stringhead to about a 30 degree angle to the left. 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. 8B)

EDGING FUNCTION: (MTK 24 only)
