Cleaning And Maintenance - Scheppach MGT410 Originalbetriebsanleitung

Condition of the chainsaw
Inspect the chainsaw before the start of work for dama-
ge to the housing, the power cable, the saw chain and
the cutter rail. Never use a chainsaw which is obviously
damaged.
Oil container
Fill level of the oil container. Even while working, keep
checking that suffi cient oil is in the system. To avoid
damaging the chainsaw, never run the saw if there is no
oil in the system or if the oil drops below the "min" mark.
On average, a single fi lling will last around 20 minutes
depending on the number of pauses in cutting and the
loads involved.
Saw chain
Tension of the saw chain, condition of the cutting ele-
ments. The sharper the chainsaw, the easier and more
controllable it is to operate the chainsaw. The same
also applies to the chain tension. Also while working
you should check the chain tension no less than every
10 minutes in order to increase your safety. New saw
chains in particular often tend to expand more.
Safety clothing
Always wear appropriate tight-fi tting safety clothing like
special trousers which protect against cuts, protective
gloves and safety shoes.
Hearing protection and protective goggles.
Wear a protective helmet with integral face and hearing
protection. This will off er protection against falling
branches and any branches if they spring back.
Safe working
• To ensure that you can work in safety you must use
the equipment at a working angle of max. 60°.
• Never stand under the branch you want to saw.
• Use special caution when working with branches

under tension and splintered wood.
• Possible risk of injury caused by falling branches and
catapulting pieces of wood.
• When the equipment is in operation keep other per-
sons and animals away from the danger zone.
• The equipment is not protected from electric shock
through contact with high-voltage cables. Keep a mini-
mum distance of 10 m from live cables. Electric shock
can cause fatal injury.
• When working on slopes always stand to the upper or
left or right side of the branch you wish to cut.
• Hold the equipment as close as possible to your body.
This will help you to keep your balance.
Cutting techniques
• When removing branches, hold the equipment at an
angle of max. 60° to the horizontal to avoid being hit
by a falling branch (Fig. 15.1).
• Start with the bottom branches on the tree. This will
make it easier for the cut branches to drop.
• After completing a cut, the weight of the saw will
abruptly increase for the operator as the saw is no
longer supported by the branch. This can result in you
losing control over the saw.
• Remove the saw from the cut only with the saw chain
still running. This will prevent the saw from getting
jammed.
• Never cut with the tip of the saw.
• Never cut into the bulging branch
Sawing off smaller branches (Fig. 16):
Place the contact surface of the saw onto the branch.
This will prevent the saw from making jerky movements
when you begin a cut. Exerting slight pressure, guide
the saw from the top to the bottom through the branch.
Sawing off larger and longer branches (Fig. 17):
Carry out a relief cut when working on larger
branches. Start by sawing through 1/3 of the branch
diameter (a) from the bottom to the top with the top side
of the cutter rail. Then saw towards the fi rst cut (b) from
the top to the bottom with the bottom side of the cutter
rail.
Saw off longer branches in several steps to keep control
over the impact location.
Kick-back!
The term "kickback" describes what happens when the
running chainsaw suddenly kicks upward and backward.
Usually, this is caused by contact between the tip of the
cutter rail and the workpiece or the saw chain becoming
trapped.
In the event of kickback, large forces occur suddenly
and violently. As a result, the chainsaw usually reacts
uncontrollably. This can often result in very serious
injuries to the worker or persons in the vicinity. The risk
of kickback is at its greatest when the saw is positioned
for a cut in the region of the tip of the cutter rail, as the
leverage eff ect is greatest there. It is therefore safest to
position the saw as fl at as possible.
Important!
• Make sure that the chain tension is always correctly
adjusted.
• Only use a chainsaw if it is in perfect working order.
• Only work with a saw chain that has been properly
sharpened in accordance with the instructions.
• Never cut with the upper edge or the tip of the cutter
rail.
• Always hold the chainsaw fi rmly with both hands.
Cutting wood which is under tension
Special care is required when cutting wood which is
under tension. Wood which is under tension from which
it is released by cutting may in some cases react com-
pletely unpredictably and uncontrollably. In the worst
case this could result in extremely severe or even fatal
injuries. This type of work must only be performed by
persons who have been specially trained.

Cleaning and maintenance

Danger!
Remove the battery pack before doing any cleaning and
maintenance work.
Cleaning
• Regularly clean the clamping mechanism by blowing it
out with compressed air or cleaning it with a brush. Do
not use tools for cleaning.
• Keep the handles free of grease so that you can
maintain a fi rm grip.
• Clean the equipment as required with a damp cloth
and, if necessary, mild washing up liquid.
• If the chainsaw is not to be used for an extended pe-
riod of time then you should remove the chain oil from
the tank. Briefl y immerse the saw chain and the cutter
rail in an oil bath and then wrap them in oil paper.
• Never immerse the equipment in water or other liquids
in order to clean it.
• Use a brush to remove deposits from the safety
guards.
• Keep all safety devices, air vents and the motor
housing free of dirt and dust as far as possible. Wipe
