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.

Rev 2

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.

may cause damage to internal parts.

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.

4.3.3.5. Should the machines performance gets worse contact an authorised service centre

who can adjust the carburettor accordingly?

4.3.4. Adjusting the idle speed.

4.3.4.1. A screw just behind air filter cover regulates

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.
