FOLLOW INSTRUCTION FOR CHANGING ACCESSORIES
SAFETY PRECAUTIONS
1. Before beginning work, check the worksite carefully to see whether there are any obstacles to be removed or avoided and whether there are any potholes or obstructions which might cause you to lose your footing.
2. The area within a radius of 15m of the brush cutter should be considered a hazardous area into which no one should enter while the brush cutter is in use. If necessary, yellow warning rope or warning signs should be placed around the work area.
When work is to be performed simultaneously by two or more persons, constantly be aware of the location of other operators to maintain a safe separation distance.
3. Make sure that there are no loose screws or bolts, fuel leaks or any other problems, which might result in unsafe operation.
Be especially careful to check the blades and their fastening arrangements.
4. Never use blades that are bent, warped, cracked, broken or damaged in any way.
5. Always keep metal blades sharp by filing the cutting edges, particularly at the outer ends.
There should be a radius at the inside end of the cutting edge.
• Never touch the nylon cutting head when ever the engine is running. If it is necessary to adjust the protector or nylon cutting head, be sure to stop the engine and confirm that the nylon cutting head has stopped running
• The engine should be turned off when the machine is moved between work areas
• Be careful not to hit the nylon cutting head against stones, or the ground. Unreasonable rough operation will shorten the life of the machine as well as create an unsafe environment for yourself and those around you
• Pay special attention to operation in the rain or just after the rain as the ground may be slippery
• When the machine is placed in storage for a long time, drain fuel from the fuel tank and carburetor, clean the parts, move the machine to a safe place and confirm that the engine is cooled down
• It is believed that a condition called Raynaud’s phenomenon, which affects the fingers of certain individuals may be brought about by exposure to vibration and cold. Exposure to vibration and cold may cause tingling and burning sensations followed by loss of color and numbness in the fingers. The following precautions are strongly recommended because the minimum exposure which might trigger the ailment is unknown.
Keep your body warm, especially the head, neck, feet, ankles, hands and wrists. Maintain good blood circulation by performing vigorous arm exercises during frequent work breaks and also by not smoking.
Limit the hours of operation. Try to fill each day with jobs where operating the brush cutter or other hand-held power equipment is not required.
4
If you experience discomfort, redness and swelling of the fingers followed by whitening and loss of feeling, consult your physician before further exposing yourself to cold and vibration
• Always wear ear protection, as being exposed to loud noise for long time can result in diminished hearing or even loss of hearing. Total face and head protection must be worn to prevent bodily injury from either slipping or falling into shrubbery, branches,or bushes.
• Wear no-slip heavy duty work gloves to improve your grip on the brush cutter handle. Gloves also reduce the transmission of machine vibration to your hands
SAFETY MAINTENANCE
1. Perform the regular maintenance procedures described in this manual. Repair and maintenance procedures other than those detailed in this manual should be carried out only by an authorised service dealer.
2. Under no circumstances should you take apart the brushcutter or alter it in any way. Doing so can result in damage to the machine, and may negate the manufacturer warranty.
3. Always be sure to turn off the engine before performing any maintenance or checking procedures.
4. To prevent injury when sharpening, removing, or reattaching the blade, be sure to wear thick, sturdy gloves and use only proper tools and equipment.
5. When replacing the blade or any other parts, always be sure to use only genuine MORRISON spares.
Before Starting the engine
1. Take a careful look around to make sure that there are no obstacles within a radius of 15m around the brush cutter.
2. Place the body of the brush cutter onto the ground in a flat clear area and hold it firmly in place to ensure that the blades will not contact anything when the engine starts.
3. Place the trigger grip in the START position when starting the engine. Do not start the engine at full speed. (See STARTING
THE ENGINE, page 8.)
4. After starting the engine, if the blades continue to rotate when the trigger grip has been released to the idle position, turn off the engine and check that the trigger grip cable is functioning correctly.
KICKBACK SAFETY PRECAUTIONS
A dangerous reaction may occur if the spinning blade contacts a solid object. It is called kick back. As a result, the operator can lose control of the unit, resulting in a serious accident.
WORKING GEAR AND CLOTHING
To avoid kick back, observe the following safety precautions:
1. Before beginning work, check your working area and remove any obstacles.
2. Grip your brushcutter only by the handles.
3. When using your brushcutter, always look closely at where you are cutting. If you need to look away, set the engine to idling speed.
4. When the engine is running, always keep the cutter head well away from your feet, and never lift it above waist level.
OPERATING SAFETY PRECAUTIONS
1. Grip the brush cutter firmly with both hands, using the correct\ hand positions. When not cutting, set the engine speed to idling.
2. Always be sure to maintain a safe footing while working.
3. Run the engine no faster than the speed required to cut cleanly.
4. If grass gets caught in the blade during operation, or if you need to check the unit or refuel the tank, always be sure to turn off the engine.
5. If the blade touches a hard object like a stone, immediately stop the engine and check the blade. If necessary, replace the blade by new one.
6. If someone calls out while you are working, always be sure to turn off the engine before turning around.
7. Never touch the spark plug or plug cord while the engine is running. Doing so may result in receiving an electrical shock.
8. Never touch the muffler, spark plug, or other metallic parts of the engine while the engine is running or immediately after shutting down the engine as serious burns may result.
9. Stop the engine when moving from one work location to another.
NOTES OF TRANSPORTATION
1. If a metal cutting blade is fitted, wrap it with a cloth to cover the sharp cutting edges.
2. When transporting by car, fix the unit firmly using a rope. It is dangerous to transport the brushcutter by cycle or motorcycle.
3. When travelling distances or over rough roads, fuel may spill from the tank. To avoid this, empty the tank before the journey.

Debris
Cut on this side
CUTTING USING THE METAL BLADE
(1) For shrubs & thick weeds
(2) For grass and weeds
(3) Direction of cutting
(4) Direction of rotation
1. A metal blade cuts best with a swathe up to one third of the cutter diameter. Use that area for cutting shrubs, tough and thick weeds. For cutting young grass, you can use up to two thirds of the cutter diameter.
2. Adjust the engine speed according to the material being cut.
Cut the young grass at middle speed, and shrubs or tough and thick weeds at high speed.
If the cutting speed is too low, debris can be caught up in the blade, and if this causes the clutch to slip it will wear out quickly.
Counter clock wise rotation
WARNING!
The proper debris shield must be in place on the unit when nylon cutting line is used. The cutting line can flap around if too much line is exposed. Always use the plastic debri shield with cut-off knife when using nylon cutting heads.
For nearly all cutting, it is good to tilt the line head so that contact is made on the part of the line circle where the line is moving away from you and the debris shield. (See appropraite picture) This results in the debris being thrown away from you.
WARNING!
Tilting the head to the wrong side will shoot the debris
TOW ARDS you.If the line head is held flat to the ground so that cutting occurs on the whole line circle, debris will be
THROWN at you, drag will slow the engine down, and you will use up a lot of line.
CUTTING WITH THE NYLON CUTTER
• Cutting with the nylon cord consumes more power so the engine speed should be 50% greater than when using the metal blade.
• The nylon cord cuts the grass by meeting it at high speed. If you take too wide a swathe you may slow down the engine and not get clean cutting. To correct this, retract the cutter from the grass until the engine regains full speed and then cut using a narrower swathe.
• After a time the nylon cord will wear away. To restore the full cutting diameter, simply bump the cutter head on the ground while it is running at full speed. The cords will extend automatically and will be trimmed to the correct length by the cord trimmer blade mounted on the guard.
• Cut grass by swinging the brushcutter from left to right . While you can cut in either direction, if you follow these suggestions the cut grass will be thrown away from you, and you will avoid getting your clothes dirty.
WARNING!
Use only quality nylon monofilament line of the diameter
2.5mm. Never use wire or wire-reinforced line in place of nylon trimmer line. Load your nylon line cutting head only with nylon trimmer line of the proper diam eter.
WARNING!
Use extreme caution when operating over bare spots and gravel,because the line can throw small rock particles at high speeds. Debris shields on the unit cannot stop objects which bounce or ricochet off hard surfaces.

Trimming
Knife side raised
Angle to ground
Debris
Edging
Angle to wall
Scalping
WARNING!
Do not use a steel blade for edging or scalping.
SCALPING & EDGING
Both of these are done with the line head tilted at a steep angle
Scalping is removing top growth leaving the earth bear. Edging is trimming the grass back where it has spread over a sidewalk or drive way. During both edging and scalping, hold the unit a steep angle and in a position where the debris, and any dislodging dirt and stones, will not come back towards you even if it ricochets off the hard surface. Although the picture shows how to edge and scalp every oprator must find for himself the angles which suits his body size and cutting situation.
WARNING!
Do not trim in any area where there are strands of fencing wire. Wear protective safety protecting, Do not cut where you cannot see what the cutting device is cutting.
CUTTING WITH A BLADE
CUTTING WITH A BLADE
There are many different types of blades, however the two most commonly used are the following.
BRUSHBLADE is used for cutting brush and weeds up to 3/4” in diameter. Only CG420-2 255mm 3-blade can be used in this type of brush cutter.
WARNING!
Do not touch these types of objects with blade
Utility Wires Metal Stakes Rubber
Rocks Masonary Fences
WARNING!
Do not use a brushcutter for cutting trees.
Avoid Wire
WARNING!
Do not cut with dull, cracked or damaged metal blade.
Before cutting growth, inspect for obstructions such as boulders, metal stakes or strands of wire from broken fences. If an obstruction cannot be removed, mark its location so that you can avoid it with the blade. Rocks and metal will dull or damage a blade. Wires can catch on the blade head and flap around or be thrown into the air.
TRIMMING
This is feeding the trimmer carefully into the material you wish to cut.Tilt the head slowly to direct debris away from you. If cutting up to a barrier such as fence, wallor tree,approach from an angle where any debris ricocheting off the barrier will fly away from you.
Move the line head slowly until the grass is cut right up the barrier, but do not jam( overfeed )the line into the barrier. If trimming up to a wire mesh or chain linked fence be careful to feed only up to wire. If you go to far the line will snap off around the wire. Trimming can be done to cut through weed stems one at a time. Place the trimmer line head near the bottom of the weed-never high up which could cause the weed to chatter and catch the line. Rather than cut the weed right through, just use the very end of the line to wear through the stem slowly.
Blade thrust is the reaction which may occur when the spinning blade contacts anything it cannot cut. This contact may cause the blade to stop for an instant, and suddenly “thrust” the unit away from the object that was hit. This reaction can be violent enough to cause the operator to lose control of the unit. Blade thrust may occur without warning if the blade snags, stalls or binds. This is more likely to occur in areas where it is difficult to see the material being cut. For cutting ease and safely, approach the weeds being cut from the right to the left,in the event that an unexpected object or woody stock is encountered, this could minimise the blade thrust reaction.
10
SCYTHING WEEDS. This is cutting by swinging the blade in a level arc. It can quickly clear areas of field grass and weeds. Scything should not be used to cut large, tough weeds or woody growths.

Push the locking latch located laterally on the spool housing (see picture, action 1).
Push the locking latch located laterally on the spool housing (see picture, action 1). Then turn the cover clockwise by about 1.5 cm
(see picture, action 2). This will unlock the cover 5 and it can be removed. Now remove the Tap’n go button 4 a nd then the usedup spool 3 from the spool housing. Pass the two line ends of the new spool th rough the eyelets in the spool housing as shown in the picture . The line ends still stay clamped in the two transpo rt clamps pf the spool.
Put the line spool in the spool housing. Please turn the spool such that the clamped line ends are located directly in front of the eyelets of the spool housing. Make sure that the spring 2 is properly seated anunder the spool. Now put the Tap’n go button back on the spool.
Then place the cover onto the 4 guiding pins and lock it in place by turning it anti-clockwise by about 1.5cm. Now vigorously pull on both line ends at the same time. This will loosen them from the transport clamps of the spool. The cutting head is now ready for operation.
You may also coil up the line yourself. If you do so, use the required line with a diameter of 2.5 mm only.
NOTE
Do not use a brush blade to cut trees which exceed a diameter of
1/2 to 3/4 inches.
Scything can be done in both directions, or just in one way which results in the debris being thrown away from you.
That is using the side of the blade that it is rotating away from you.
Tilt down the blade slightly on this same side .You will be hit by some debris if you scythe in both directions.
Do not force the blade to cut. Do not change the angle of cut after into the wood. A void using any pressure or leverage which could cause the blade to bind or crack.
MAINTAINENCE
BLADE
• Sharpen each cutting edge and make sure the inside corner is rounded to reduce the risk of cracking.
• Do not quench the blade with water if you are using a grinder as it may start cracks in the blade.
• The 3 tooth blade may be inverted utilise a fresh set of cutting edges.

NYLON CUTTERS
The spools of nylon cord inside these bump-feed cutter heads will eventually need replacing. While the change can be made with the cutter head on the machine, it will be more convenient to remove the cutter head.
CHANGING THE SPOOL
The cutting head consists of the following parts:
Use 2 separate lines with a length of about 2.1m each.To Þx the line ends the spool has 2 eyelets. Put the end of each thread into an eyelet. Put the line into the eyelet in the direction of the arrow as shown on the bottom side of the spool. Put each line end in by about 2cm. Now grab both lines with one hand and concurrently coil them up in the direction of the arrow.
Finally, fix the line ends by putting each in one of the transport clamps as shown in the picture. The spool can now be installed.
Proceed as described above to install the spool.
NOTE:
Both nylon cords need to be wound in the same direction

Check the filter element and clean it in warm, soapy water as required. Dry completely before installing. If the element is broken or shrunk, replace with a new one.
(1) Air Cleaner element.
IDLE ADJUSTMENT SCREW
The horizontal screw (1) contacting the side of the butterfly lever arm on top of the carburettor adjusts the idling speed. If you turn right (clockwise), idle speed increases, and left (counterclockwise) it decreases. Adjust the speed if the blade continues to rotate when the engine is idling, or if the engine stops when you release the throttle lever.
A clogged air filter will increase fuel consumption and cut down the engine power.
If you operate the brushcutter without the air filter or with a deformed filter element it will quickly ruin the engine.
FUEL FILTER
Take the filter out of the fuel tank using a small wire hook.
Disconnect the filter assembly from the fuel pipe and unhook the retainer to disassemble it. Clean the components with petrol.
A clogged fuel filter will reduce the power of the engine.
SPARK PLUG
Remove and inspect the spark plug and clean the electrodes as necessary with wire brush.
The spark gap should be adjusted to 0.6~0.7mm.
If a new spark plug is fitted it must be the same type as the original one.
COOLING AIR INTAKE VENT
• Check the cooling air intake vent and the area around the cylinder cooling fins, and remove any waste which has attached itself to the brushcutter.
• Failing to keep the air path clear could cause the muffler to become overheated, and this in turn could cause the brushcutter to catch on fire.
GEAR CASE
• Remove the screw from the side of the gearbox.
• Remove the cutter and the inner flange to allow old grease to exit.
• Using a grease gun, supply multi-purpose grease after every 25 hours of use.
AFTER 100 HOURS USE
MUFFLER
1. Remove the muffler, insert a screwdriver into the vent, and scrape away any carbon buildup. Scrape away any carbon build-up on the muffler exhaust vent at the same time.
2. Tighten all screws, bolts, and fittings.
3. Undo the four socket screws holding the engine to the housing at the top of the main tube and check to see if any oil or grease has worked its way in between the clutch lining and drum If it has, wipe it away using oil-free, lead-free petrol.
ADJUSTING THE CARBURETTOR
A wrong adjustment may cause damage to your unit. If the engine does not run well after adjusting the carburettor, please contact your service agent.
Adjustments & service are not covered by warranty.

MAINTENANCE BEFORE STORAGE
1. Clean the machine down thoroughly and inspect for any wear or damage. If you find any, have it corrected so the machine will be ready for use next time.
2. Empty the fuel from the tank. If the engine will start, run it until it stops from lack of fuel.
3. Remove the spark plug and put in 1~2 drops of 2-cycle oil in the engine. Pull the starter rope 2~3 times and then replace the
4. spark plug.
5. Apply anti-rust oil to the metal parts such as the throttle wire, put the cover on the blade, and store it indoors, avoiding dampness.
