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.
