The most common effects are:
• setback
• recoil,
• retreat
Kickback
The setback can occur when the moving saw chain
meets at the upper quarter of the guide rail on a solid
object or is pinched.
The cutting force exerted on the chain from the saw,
a rotational force in the opposite direction to the
chain travel. This leads to an upward movement of
the guide rail.
Avoid kickback
The best protection is to avoid situations that lead to
setbacks.
1. Keep the position of the upper guide rail always
in mind.
2. Leave this place never come into contact with an
object. Cut anything with it. Be especially careful
near wire fences and cutting small, hard knots, in
which the chain can easily pinch.
3. Cut only one branch at a time.
Withdrawal
The withdrawal occurs when the chain on the under-
side of the bar suddenly stuck because it is jammed
or encounters a foreign object in the wood. The chain
then pulls the saw forward. The withdrawal often
happens when the chain is not running at full speed
when in contact with the wood.
Avoid withdrawal
Be aware of the forces and situations that can lead
to jamming of the chain on the underside of the bar.
Always start with running at full speed chain to cut.
Recoil
The recoil occurs when the chain on top of rail sud-
denly stuck because it is jammed or encounters a
foreign object in the wood. The chain can jerkily hold
the saw against the operator. Rebounds happen of-
ten if the top rail is used for cutting.
Avoid recoil
Be aware of the forces and situations that can lead to
jamming of the chain on top of rail.
Do not cut more than one branch at a time.
Do not tilt the rail to the side when you pull them out
of a cutting gap, since the chain could get caught
otherwise.
Operation Leaf blower
Do not smoke while refueling or operating equipment.
•
Do not touch or let your hands or body come in
•
contact with a hot muffler or spark plug wire.
Due to the danger of exhaust fumes, never oper-
•
ate blower in a confined or poorly ventilated area.
• Use the tool only in broad daylight or in well-lit
conditions.
Do not underestimate the forces involved. Make
•
sure you stand squarely and keep your balance
at all times.
If possible, avoid using the tool on wet grass.
•
• Ensure that you maintain a steady foothold particu-
larly while working on slopes.
Always walk. Never run.
•
Always keep the ventilation opening clean.
•
Never direct the blow hole at persons or animals.
•
The machine may only be used at reasonable times
•
of the day, i.e. not in the early morning or late even-
ing when it will be a nuisance to other people. Per-
mitted times of use specified by local authorities
must be observed.
The machine must be run at the lowest possible
•
motor speed required to carry out the work.
Remove all foreign objects with a rake and brush
•
before starting any blowing work.
• Where conditions are dusty, dampen the surface
a little or use a sprinkler attachment.
Use the full-length blower nozzle extension so that
•
the air current can work near to the ground.
Watch out for children, pets, open windows etc. and
•
blow the foreign objects safely away from them.
• If the device makes abnormal noises or has unu-
sually high levels of vibration, it must be checked.
Unusually high levels of vibration can injure the
operator and damage the unit.
Never operate the appliance with defective guards
•
or shields, or without safetydevices, for example
debris collector in place
• Do not expose the hot engine to flammable ma-
terials
The Blower can be used to blow debris from patios,
•
paths, driveways, lawns, bushes and borders.
Select the blow function using the selector lever
•
on the side of the machine and switch on.
Alternatively hold nozzle just above the ground
•
and swing the machine from side to side, moving
forwards and direct the nozzle at the debris to be
cleared.
Blow the debris into a convenient heap
•

10. Maintenance

WARNING: Always wear protective gloves when
working on or around cutting tools. For non­use,
transport or storage always attach the transport
guard to all cutting tools. Fig. 1 (14a, 15a, 17a)
Before performing any maintenance or cleaning
work, always turn off the engine and pull out the
spark boot plug.
1. Do not spray the unit with water. It damages the
engine.
2. Clean the unit with a cloth, hand brush, etc.
