Maintenance - Scheppach TPX710 Traduction Des Instructions D'origine

Always observe the condition of the tree.
Look for rot and decay in the roots and branches.
If they are rotten inside, they can break off and fall down
unexpectedly during cutting. You could also attend by
fractured and dead branches out, which is solved by the
shake and fall on you. For very thick or heavy branches
you first make a small incision below the branch before
you work from the top down to avoid chipping.
Basic cutting technique
Heavy branches break off easily when sawing. They tear
long strips of bark away from the trunk, which damages
the tree sustainably. The following section technique can
significantly reduce this risk:
Saw the first branch about 10 cm from the trunk.
Put in about 15 cm from the base of the top of a further
section.
Saw until the branch breaks. The risk of injury on the
trunk is no.
Finally, remove with a clean cut from the top of the trunk
along the remaining.
Thus, the damage to the tree are kept as low as possi-
ble, we recommend the interface additionally to seal with
grafting wax.
Hazards by reactive forces
Reactive forces occur during operation of the saw chain.
The forces which are applied to the wood are against the
operator. They occur when the moving chain comes into
contact with a fixed object such as a branch or is pinched.
These forces can lead to a loss of control and injury.
Understanding the origin of these forces can help you to
avoid the scare and the loss of control. This saw is desi-
gned to make the return effects are not as noticeable as
with traditional chainsaws.
Always still keep a firm grip and a good level to maintain
control of the tool in doubt.
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 ob-
ject 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 set-
backs.
Keep the position of the upper guide rail always in mind.
Leave this place never come into contact with an ob-
ject. Cut anything with it. Be especially careful near wire
fences and cutting small, hard knots, in which the chain
can easily pinch.
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 hap-
pens 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 sudden-
ly 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 often 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.

9. Maintenance

NJURY WARNING!
Before working on the device, disconnect the mains
cable from the socket.
Always wear protective gloves when working on or
around cutting tools.
• Regularly check the device before starting work.
• Damaged blades have to be repaired or replaced by
an authorised service department before you can work
with the device.
• Clean the blades with a soft brush after working with
the device and spray a thin layer of liquid protective oil
on the whole blade.
• Always keep the ventilation holes in the motor casing
free and clean.
• Never use water to clean or spray the device. Clean
the motor casing with a damp cloth and never use de-
tergents or solvents! This may damage the device's
plastic parts. Dry the motor casing carefully afterwards.
• Always store the machine with the supplied protective
cover.
• Only use OEM parts for maintenance work. Using parts
other than original parts can cause damage to the ma-
chine.
Servicing and sharpening of saw chain
The correct sharpened chain
Working effectively with the chainsaw is only possible if
the chain is in good condition and
sharp. This also reduces the risk of kickback.
