8. After clamping the sawing chain, raise the front
cutter end and tighten the nuts (5).
Note: The noise that occurs when the chainsaw
runs out without cutter and sawing chain is design-
related and has no influence on operation and
service life of the machine.
7.2
Running-in sawing chain
Before sawing with a new sawing chain, allow it to
run in for 2-3 minutes.
After the run-in time, check the chain tension
(as specified in chapter 7.1) and retighten the
chain if necessary.
7.3
Chain lubricating oil
The chainsaws are delivered ex works
without an
oil filling
.
Prior to initial operation of the
machine, the oil reservoir must be filled with
lubricating oil.
Use only original Metabo chainsaw adhesive
oil. Never use old oil!
Metabo chainsaw adhesive oil is biologically
degradable and permits chainsaw operation at
temperatures as low as -15 °C.
The sealing cap (6) is removed to fill the oil. When
filling the oil, ensure that no dirt gets into the oil
reservoir. The oil level can be monitored at the oil
sight glass (20).
The adjusting screw (7) can be used to change the
oil delivery volume. For sawing hard, dry wood and
for working with the entire useful length of the
cutter, set the screw to "+". For sawing soft and
wet wood (or if only a section of the cutter is
engaged), the oil delivery volume can be reduced
accordingly by turning the screw in direction "-".
Depending on the outside temperature and set oil
delivery volume, one filling of the oil reservoir
(capacity 0.2 l) is sufficient for 15 to 40 minutes
chainsaw operation.
7.4
Checking chain lubrication
If the sawing chain is running dry, the cutter and
sawing chain are rendered useless within a short
time. It is therefore essential to check the oil level
in the reservoir every time before starting work.
Never work without chain lubrication!
To check the chain lubrication, hold the chainsaw
with the cutter (and sawing chain running) at a safe
distance of about approx. 20 cm over a light-
coloured base, e.g. a spread-out newspaper). If
increasingly large oil mark appears on the light-
coloured base, the chain lubrication is working
perfectly.
7.5
Chain brake
The integrated chain brake brings the sawing chain
to a standstill within 1/10 of a second if the hand
protection (9) is moved either
- manually to its front position, or during work with
the chainsaw with the back of the operator's
hand (due to a back-kick), or
- the chainsaw is switched off by releasing the
trigger.
If the quick brake of the chainsaw is tripped
through actuation of the hand protection (9), do
not allow the chainsaw motor to run with the hand
protection in this position for unnecessarily long
periods. Guide the hand protection back to its
initial position.
Before operating the chainsaw, always
check that the chain brake is in perfect
working order (by actuating the hand protection
and releasing the trigger). Have the machine
repaired if braking time is lengthened.
7.6
Mains connection
Before plugging in, check to see that the
rated mains voltage and mains frequency, as
stated on the rating label, match your power
supply.
Prior to starting work, check the mains
connection cable and extension cable for
damage. Only use mains connection cables and
extension cables in perfect condition.
The electrical system to which the chainsaw
is connected should be equipped with a
differential current safety switch (with a max. of
30 mA release current).
The chainsaw is intentionally short to prevent it
from coming into contact with the running sawing
chain when working with the machine.
It is advisable to fit the strain relief belt between the
chainsaw plug and the coupler socket of the
extension cable required for work with the
machine. This prevents the plug from accidentally
slipping out of the extension cable coupler socket.
8.1
Switching on and off
When the chainsaw is switched on, the oper-
ator must keep good footing and hold the
machine firmly. The cutter must not touch any
objects.
Switching on
The hand protection (9) must be in its initial posi-
tion when the machine is switched on, i.e. pressed
in the direction of the arrow (illustration 1) against
the handle (8).
