Operation - McCulloch HT 5622 Bedienungsanweisung

a WARNING: Muffl er is very hot during and
after use. Do not touch the muffl er or allow
combustible material such as dry grass or fuel to
do so.
a WARNING: Be sure to read the fuel information
in the safety rules before you begin. If you do not
understand the safety rules, do not attempt to fuel
your unit.
FUELING THE ENGINE
a WARNING: Remove fuel cap slowly when
refueling. Never remove the fuel cap or add fuel
with the engine running. Allow engine and muffl er
to cool down before refueling.
This engine is certifi ed to operate on unleaded petrol.
Before operation, petrol must be mixed with a good quality
synthetic 2-cycle air-cooled engine oil designed to be
mixed at a ratio of 50:1. A 50:1 ratio is obtained by mixing
77 ml of oil with 4 litres of unleaded petrol. DO NOT USE
automotive oil or boat oil. These oils will cause engine
damage. When mixing fuel, follow instructions printed on
oil container. Once oil is added to petrol, shake container
momentarily to assure that the fuel is thoroughly mixed.
Always read and follow the safety rules relating to fuel
before fueling your unit.
CAUTION: Never use straight petrol in your unit. This
will cause permanent engine damage.
FUEL REQUIREMENTS
The lowest recommended octane grade is 90 (RON).
IMPORTANT
Use of alcohol blended fuels more than 10% alcohol can
cause major engine performance and durability problems.
CAUTION: Alternative fuels (not petrol) such as E-15
(15% alcohol), E-20 (20% alcohol), E-85 (85% alcohol)
are NOT classifi ed as petrol and are NOT approved
for use in 2-stroke petrol engines. Use of alternative
fuels will cause problems such as: improper clutch
engagements, overheating, vapor lock, power loss,
lubrication defi ciency, deterioration of fuel lines,
gaskets and internal carburetor components, etc.
Alternative fuels cause high moisture absorption into
the fuel/oil mixture leading to oil and fuel separation.
ADDING FUEL
• Remove the fuel cap and pour mixed fuel into the fuel
tank.
• Replace fuel cap tightly.
• Move at least 3 metres away from the fueling site.

BASIC WORKING TECHNIQUES
• Work with a swinging action from the bottom upwards
when trimming sides. See Picture 21.
• When trimming a hedge the engine should always face
away from the hedge.
• Hold the machine as close to your body as possible to
get the best balance.
• Make sure that the tip does not touch the ground.
• Do not rush the work, but work steadily until all the
branches have been cut back cleanly.
It is recommended that the engine not be operated for
longer than 30 seconds at full throttle. Releasing the
trigger and allowing the engine to briefl y return to idle
speed (5 - 10 seconds) will be suffi cient.
Note: Use the minimum throttle speed necessary
to effectively cut hedges for optimal hedge trimmer
performance.
The handle adjustment lever can be used to rotate the
rear handle to allow operation of the unit at a 45° and 90°
position.
1. Allow engine to return to idle speed.
2. Pull handle lever and rotate rear handle to desired
position.
3. Release handle lever.
