FUEL HANDLING WARNING
1. For Honda 4 stroke engines:
Fuel and oil are not to be mixed, they fill separate tanks. Use
unleaded gasoline for fuel and automotive 4 cycle oil for the oil
tank. Do not store cans of fuel or refill the fuel tank in any place
where there is a boiler, stove, wood fire, electrical or welding
sparks, or any other source of heat or fire which might ignite
the fuel.
2. Smoking while operating the line trimmer or refilling its fuel tank
is extremely dangerous. Always be sure to keep lit cigarettes
away from the line trimmer at all times.
3. When refilling the tank always turn off the engine first, wait for it
to cool, and take a careful look around to make sure that there
is nothing nearby which might ignite spilled fuel.
4. To avoid spilling fuel, always use a funnel when filling the fuel
tank.
5. If any fuel spillage occurs during refuelling, use a dry rag to
wipe up the spillage before starting the engine again.
6. After refuelling, screw the fuel cap back tightly onto the fuel
tank and then carry the line trimmer to a spot 3m or more away
from where it was refuelled before starting the engine.

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 line trimmer should be
considered a hazardous area into which no one should enter
while the line trimmer 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 cutting devices and their
fastening arrangements.
WARNING
Never use other cutting devices than those provided
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 line trimmer.
2. Place the body of the line trimmer 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.
To avoid kick back, observe the following safety precautions:
1. Before beginning work, check your working area and remove
any obstacles.
2. Grip your line trimmer only by the handles.
3. When using your line trimmer, 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 line trimmer 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.
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 line trimmer
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.
Notes on 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 line trimmer 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.

WHEN THE ENGINE HAS BEEN WARMED
UP
1. Fully open the choke lever.
2. Follow steps 7-2 starting a cool engine.
3. If the engine does not start, repeat step
2 procedure for starting a cool engine.
CAUTION
1. After starting the engine, accelerate and decelerate the
engine several times by opening and closing the throttle
trigger to remove air from the carburettor.
2. Air in the carburettor cause poor acceleration or engine
stoppage.
3. Re-fuel before the fuel is used up, Starting the engine
after using up the fuel is very difficult.
BEFORE OPERATION
After starting the engine, warm it up about 3
minutes and increase the speed gradually.
STOPPING THE ENGINE
Do not suddenly stop the engine when operation at high speed.
Gradually return the throttle trigger and idle the engine before
setting the switch to STOP.
CAUTION
Do not operate the engine at high speeds with no load on
the cutting attachment, especially when the engine is new.
When operated at high speeds with no load, the speed will
accelerate to excessively high that might harm the engine.
WHEN THE ENGINE DOES NOT START
If the engine does not start or flames flow back through the muffler
even though you have pulled the starter many times, remove and
check the spark plugs.
1. If the spark plugs are dry, no fuel has been fed into the cylinder.
Check the fuel pipe and carburettor.
2. Clean or replace the spark plugs if they are wet or dirty.
3. If fuel has overflowed into the crank case, remove the spark
plugs, open throttle and pull the starter 2 or 3 times to remove
excess fuel from the crank case.
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 line trimmer from right to
left. 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.
Maintenance
CLEANING AIR CLEANER
Wash or replace the cleaner when it
becomes dirty.
1. Detach the cleaner mounting
screws and remove the cleaner
cover.
2. Remove the elements, wash or
replace the element.
SPARK PLUG
The spark plugs have a standard
electrode-to-electrode distance of
0.6 to 0.7mm Fig. 12
The spark plug electrodes are dry and
drowned under optimum operating
conditions. Clean as necessary.
Use spark plugs designated for the engine.
FUEL FILTER CLEANING
The fuel hose has a filter at its end
(in the fuel tank) to prevent foreign
matter such as sand from entering the
carburettor. Clean the filter as required
because the pump cannot suck up fuel if
the filter is clogged, which would cause
the engine to stop. Clean or replace the
filter if it is clogged or damaged.
ADJUSTING THROTTLE CABLE
Adjust the throttle cable length with the adjusting nut. If the Nylon
cutting head rotates even after you have released your hand from
the throttle trigger to idle the engine, adjust the throttle cable length.
Loosen the lock nut and turn the adjusting nut to adjust the cable
length. Turn the adjusting nut clockwise to lengthen the throttle
and counterclockwise to shorten it. Tighten the lock nut after
adjustment.
ADJUSTING HALF THROTTLE
The trimmer has a built-in throttle-locking mechanism to keep the
throttle at half throttle for easy engine start up. Adjust the half-
throttle by changing the throttle length with the adjusting nut.
CARBURETTOR
CAUTION
The engine has been adjusted before shipment. In the case
of engine trouble, contact your distributor, because the
engine trouble is not caused by a faulty carburettor only. An
engine that is not adjusted properly will be damaged, not
only the carburettor but also the engine it’s self.
CLEANING MUFFLER
Cleaning muffler carbon after 50 hours of operation as follows:
1. Remove the muffler guard and muffler.
2. To prevent carbon from entering the cylinder, pull the starter
to turn the crankshaft, blocking the exhaust opening with the
piston.
3. Clean carbon from the cylinder exhaust opening, taking care
not to damage the surface.
4. Screw the muffler and muffler guard together securely.
5. Be sure to ask your operator to clean the muffler periodically.
