Page 11
Rev 2
3.6.9. Vertical cutting.
3.6.9.1. Use an arc cutting style from the bottom upwards, then
downwards to use both sides of the blades.
3.6.10. Horizontal cutting.
3.6.10.1. In order to get the best cutting results, slightly tilt the
blade (5-10°) towards the cutting direction.
3.6.11. Kick-back and related warnings’.
3.6.11.1. Kickback is a sudden reaction to a pinched or snagged cutting blade. Pinching or
snagging causes rapid stalling of the rotating accessory which in turn causes the
uncontrolled power tool to be forced in the direction opposite of the accessory’s rotation
at the point of the binding. For example, if a blade is snagged or pinched by the stone, the
edge of the blade that is entering into the pinch point can dig into the surface of the
material causing the blade to climb out or kick out. The blade may either jump toward or
away from the operator, depending on direction of the blade’s movement at the point of
pinching. Kickback is the result of power tool misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper precautions as given
below.
3.6.11.1.1. Maintain a firm grip on the power tool and position your body and arm to
allow you to resist kickback forces.
3.6.11.1.2. Never place your hand near the cutting accessory. Accessory may kickback
over your hand.
3.6.11.1.3. Do not position your body in the area where power tool will move if kickback
occurs. Kickback will propel the tool in direction opposite to the wheel’s movement
at the point of snagging.
3.6.11.1.4. Use special care when working corners, sharp edges etc. Avoid bouncing and
snagging the accessory. Corners, sharp edges or bouncing have a tendency to snag
the rotating accessory and cause loss of control or kickback.

3.6.12. Handle adjustment. (This for the HYT2622-II model only)
Do not press the throttle trigger during this operation!
To reduce fatigue when trimming hedges, the rear handle can be
swivelled to 3 positions, left to 90°, or right to 90°.
3.6.12.1. Proceed as follows;
3.6.12.1.1. Release the throttle trigger and throttle trigger lockout, then pull the handle
locking knob towards back.
3.6.12.1.2. Turn the rear handle until the handle locking knob clicks into place.
3.6.12.1.3. When the rear handle is locked in its new position, the user can start working
again.
3.7. Stopping.
When the engine is coming to a stop or power control is released, the cutting
attachment can still cause injury whilst it comes to a stop.
When the unit is turned off, make sure the cutting attachment has stopped before
the setting the unit down.
3.7.1. Decrease engine speed and run at idle for a few minutes.
3.7.2. Switch OFF the engine by moving the engine stop switch to the STOP position.

4.3.2.2. Some maintenance products and solvents may damage the plastic parts, these
include products containing benzene, chloride and ammonia.
4.3.2.3. Take special care to keep the ventilation inlets /outlets free from obstruction.
Cleaning with a soft brush followed by a compressed air jet will usually be sufficient to
ensure acceptable internal cleanliness.
4.3.2.4. Wear eye and hand protection when carrying out cleaning.
4.3.3. Carburettor adjustment.
4.3.3.1. The carburettor governs the engine’s speed via the throttle control. Air and fuel are
mixed in the carburettor. The air/fuel mixture is adjustable. Correct adjustment is
essential to get the best performance from the machine.
4.3.3.2. Adjusting the carburettor means that the engine is adapted to local operating
conditions, e.g. climate, altitude, petrol and the type of 2-stroke oil.
4.3.3.3. The engine has been tested in the factory with initial adjustment.
4.3.3.4. The user need not adjust the carburettor, if it continues to run at peak performance.

the throttle setting at idle speed. If it’s necessary
the user can adjust the idle speed.
4.3.4.2. Before any adjustment, make sure that the
air filter is clean and the air filter cover is fitted.
4.3.4.3. Turn the screw clockwise can give a higher
idle speed; turning it anti-clockwise gives a lower
idle speed.

Page 17
Rev 2
Grease nipple
4.3.4.4. When the idle speed is correctly adjusted when the engine runs smoothly in every
position. There should also be a clear margin to the speed at which the blades start to
move. The blades must also remain stationary when in the fast/idle position.
4.3.5. Gearbox.
4.3.5.1. There is a grease nipple and a plug for -
filing lubricant on the gear housing. Use a
grease gun to fill with grease.
4.3.5.2. This should be done after every 50
working hours. Use special grease which can
withstand high temperature and high
pressure.
The gear housing must not be filled completely with grease. The grease
expands as the machine heats up during operation. If the gear housing
was completely filled with grease it could damage the seals and lead to
leakage of grease. The grease in the bevel gear does not normally need
to be changed except if repairs are carried out.
4.3.6. Cleaning and Lubrication.
4.3.6.1. Clean any resin and plant residue from the blades
after using the machine.
