Before starting the engine
1. The area within a perimeter of 15 m (50 ft) of the person using the product should be considered
a hazardous area into which no one should enter. If necessary, yellow warning rope and/or
warning signs should be placed around the perimeter of the area. When work is to be performed,
care should also be taken to constantly look around or otherwise check for the presence and
locations of other people working so as to maintain a distance between each person sufficient
to ensure safety.
2. Check the condition of working area to avoid any accident by hitting hidden obstacles such as
stumps, stones, cans, or broken glass.
IMPORTANT: Remove any obstacle before beginning work.
3. Inspect the entire unit for loose fasteners and fuel leakage. Make sure that the cutting attach-
ment is properly installed and securely fastened.
Starting the engine
1. Keep bystanders, especially children, and animals at least 15 m (50 ft) away from the operating
point. If you are approached, immediately stop the engine.
2. The product is equipped with a centrifugal clutch mechanism; so the cutting attachment might
begin to rotate as soon as the engine is started. When starting the engine, place the product
onto the ground in a flat clear area and hold it firmly in place so as to ensure that neither the
cutting part nor the throttle come into contact with any obstacle when the engine starts.
WARNING: Never place the throttle into the high-speed position when starting the en-
gine. Never start the engine at the cutting attachment side.
3. After starting the engine, check to make sure that the cutting attachment stops rotating when
the throttle is moved fully back to its original position. If it continues to rotate even after the
throttle has been moved fully back, turn off the engine and take the unit to your authorized
servicing dealer for repair.
Using the product
IMPORTANT: Cut only materials recommended by the manufacturer, and only use the device for
tasks explained in the manual.
1. Grip the handles firmly with both hands using your whole hand. Place your feet slightly apart
(slightly further apart than the width of your shoulders) so that your weight is distributed evenly
across both legs, and always be sure to maintain a steady, even posture while working.
2. Maintain the speed of the engine at the level required to perform cutting work, and never raise
the speed of the engine above the level necessary.
3. If the unit starts to shake or vibrate, turn off the engine and check the whole unit. Do not use
it until the trouble has been properly corrected.
4. Keep all parts of your body away from rotating cutting attachment and hot surfaces.
5. Never touch the muffler, spark plug, or other metallic parts

might result in the product becoming damaged during operation or the product becoming unable
to operate properly.
Handling fuel
1. The engine of the product is designed to run on a mixed fuel, which con-
tains highly flammable gasoline. Never store cans of fuel or refill the tank
of the unit in any place where there is/are a boiler, stove, wood fire, elec-
trical sparks, welding sparks, or any other source of heat or fire which might
ignite the fuel.
2. Never smoke while operating the unit or refilling its fuel tank.
3. When refilling the tank, always turn off the engine and allow it to cool down.
Take a careful look around to make sure that there are no sparks or open
flames anywhere nearby before refuelling.
4. Wipe spilled fuel completely using a dry rag if any fuel spillage occurs dur-
ing refuelling.
5. After refuelling, screw the fuel cap back tightly onto the fuel tank and then
carry the unit to a spot 3 m or more away from where it was refuelled before
turning on the engine.

Transportation
1. When you hand-carry the product, covers over the cutting part are necessary; lift up the product
and carry it paying attention to the blade.
2. Never transport the product over rough roads over long distances by vehicle without removing
all fuel from the fuel tank. If doing so, fuel might leak from the tank during transport.
Fuel
WARNING: Gasoline is very flammable. Avoid smoking or bringing any
flame or sparks near fuel. Make sure to stop the engine, and allow it cool down
before refuelling the unit. Select outdoor bare ground for fuelling, and move at
least 3 m (10 ft) away from the fuelling point before starting the engine.
Gasoline requirements
•All 2-stroke products are powered by professional-commercial duty, hi-performance, hi-RPM,
air cooled 2-stroke engines.
•Hi-performance 2-stroke engines produce higher HP outputs as compared to standard home
owner duty or light commercial duty production engines offered by most manufacturers. Exhaust
emission are controlled by the fundamental engine parameters and components (eq., carbure-
tion, ignition timing and port timing) without addition of any major hardware or the introduction
of an inert material during combustion.
Gasoline/oil mixture storage recommendations
Store your gasoline or gasoline/oil mixture in a cool dry area in a tightly sealed approved container to
limit the entry of moisture and additional air (oxygen). Moisture and air cause the development of varnish
and gum, making the fuel stale. Stored gasoline and gasoline/oil mixture ages and loses its octane rating
and volatility. Do not mix more gasoline/oil than you intend to use in 30 days, and 60 days when fuel
stabilizer is added.
How to mix fuel
Recommended mixing ratio gasoline/oil 40:1. Pay attention to agitation.
1. Measure out the quantities of gasoline and oil to be mixed.
2. Put some of the gasoline into a clean, approved fuel container.
3. Pour in all of the oil and agitate well for 10 s.
4. Pour in the rest of gasoline and agitate again for at least 1 min. As some oils may be difficult to
agitate depending on oil ingredients, sufficient agitation is necessary. Be careful that, if the ag-
itation is insufficient, there is an increased danger of early piston seizure due to abnormally lean
mixture.
5. Place a clear indication on the outside of the container to avoid mixing up with gasoline or other
containers that do not contain oil.
6. Indicate the contents on outside of container for easy identification.
Fuelling the unit
1. Untwist and remove the fuel cap. Put the cap on a clean surface.
2. Put fuel into the fuel tank to 80 % of the full capacity.
3. Fasten the fuel cap securely and wipe up any fuel spillage around the unit.

WARNING
1. Select flat and bare ground for fuelling.
2. Move at least 3 m (10 ft) away from the fuelling point before starting the engine.
3. Stop the engine before refuelling the unit (this time to be sure to sufficiently agitate the mixed
gasoline in the container).
For the service life of your engine, avoid
1. fuel with no oil (raw gasoline), which will cause severe damage to the internal engine parts
very quickly.
2. gasohol, which can cause deterioration of rubber and/or plastic parts and disruption of engine
lubrication.
3. oil for 4-stroke engine use, which can cause spark plug fouling, exhaust port blocking, or
piston ring seizure.
4. mixed fuels which have been left unused for a period of one month or more may clog the
carburettor and result in the engine failing to operate properly.
5. In the case of storing the product for a long period of time, clean the fuel tank after emptying it
. Next, start the engine and run the carburettor dry of residual fuel.
6. In the case of scrapping the used mixed oil container, scrap it only at an authorized depository
site.
NOTE: Normal wear and change in product with no functional influence are not covered by the
warranty. Also, be careful that, if the usage in the instruction manual is not observed as to the mixed
gasoline, type of oil or fuel to be used described therein, it may not be covered by the warranty.

How to use
•The blades spacing is 28 mm. Cutting too thick twigs or metal wires can not only break the blade
teeth but also give damage to the drive mechanism. When trimming leaves and thin twigs, guide
the blades as drawing a half circle on the surface, and you will get a better finish.
•Running the engine at high speed with the blades jammed up can shorten the life of clutch parts.
When the blades have been jammed by thick twigs, stop operation at once and draw your unit
off the objects after stopping the engine. When clipping comparatively thick twigs, move your
unit slowly back and forth like a saw, and they can be cut to a fine finish.
NOTE: When a new unit is first operated, in the first few minutes grease may come out of the gear
case. But, since this is excess grease, there is no cause for alarm. For next use, just wipe it off with the
engine stopped.
Hedge trimming techniques
Trim sides of a hedge first and then top.
Vertical cut:
With the 2-sided blade model CHT2250, perform an arcing cut from the bottom
upwards, then downwards to use both sides of the blades (OP7).
Horizontal cut:
In order to get the best cutting results, slightly tilt the blade (5°–10°) towards the
cutting direction (OP8). Cut slowly, especially with thick hedges.
WARNING: Always follow the safety precautions. The hedge-trimmer must only be used to trim
hedges or small bushes. It is forbidden to cut other types of material. Do not use the hedge-trimmer as
a lever to lift, move, or break objects, nor lock it on fixed supports. It is forbidden to apply tools or
applications that are not the ones indicated by the manufacturer onto the power take-off of the hedge-
trimmer. Do not use it for pruning trees or cutting grass.

http://www.teichtip.de
first turn the plug until it is finger tight, then tighten it a quarter turn more with a socket wrench. TIGHT-
ENING TORQUE IS: 9.8–13.7 Nm (87–121 in-lbs)!
WARNING: Inspect periodically, the muffler for loose fasteners, any damage or corrosion. If any
sign of exhaust leakage is found, stop using the machine and have it repaired immediately. Note that
failing to do so may result in the engine catching on fire.
Spark arrester (MA4)
The muffler is equipped with a spark arrester to prevent red hot carbon from flying
out of the exhaust outlet. Periodically inspect and clean as necessary with a wire
brush. In some countries, it might under certain circumstances be required by law
to equip a spark arrester.
(1) spark arrester
Intake air cooling vent (MA5)
WARNING: Never touch the cylinder, muffler, or spark plugs with your bare
hands immediately after stopping the engine. The engine can become very hot
when in operation, and doing so could result in severe burns. Clean the cylinder
fins with compressed air or a brush.
(1) cylinder, (2) in-
take air cooling
vent (back)
IMPORTANT: If waste gets stuck and causes blockage around the intake air cooling vent or be-
tween the cylinder fins, it may cause the engine to overheat, and that in turn may cause mechanical
failure on the part of the hedge-trimmer.
Blades (MA6)
Oil blades each gas tank filling.
WARNING: Make sure that the blade bolts are well tightened. The blade as-
sembly is designed to automatically compensate for any play between the blades.
Sharpening (MA7)
Always keep the file or sharpener at an angle of 45° to the blade, and always grind
in the direction of the cutting edge.
Note: Files cut only in one direction. Lift the file from the blade when returning
to start a new pass. Remove every burr from the edge of the blade with a slip stone.
Remove as little material as possible. Before refitting the sharpened blades, re-
move filings and then apply grease. Do not try to sharpen a damaged blade:
change it or take it to a qualified workshop.
