Checking The Chain Tension; Directions For Use And Cutting Techniques - Alpina 3700 Manuel D'utilisation

USING THE MACHINE
• Check that the chain brake is working effi-
ciently.
– Make sure you are holding the machine firmly
with both hands when you start the engine
– Use the accelerator level to keep the chain
moving, push the brake lever forwards using
the back of you left hand; the chain must stop
immediately.
– When the chain has stopped, immediately
release the accelerator lever.
– Release the brake.

CHECKING THE CHAIN TENSION

The chain tends to stretch gradually as you
work, so you need to check its tension frequent-
ly.
WARNING!
chain loose, as it can be hazardous if the
chain slips out of its guides.
CHECKING THE OIL DELIVERY
IMPORTANT
without lubrication! The oil tank may get almost
empty every time the fuel runs out. Make sure
you top up the oil tank every time you refuel the
chain-saw.
WARNING!
the chain are in place when you check the oil
delivery.
Start the engine, keep it running at medium
power and check if the chain oil is delivered as
shown in the figure (Fig. 12).
You can adjust the chain oil flow using a screw-
driver on the adjuster screw (1 or 1a) of the oiler,
which is on the bottom of the machine (Fig. 12).
DIRECTIONS FOR USE AND CUTTING
TECHNIQUES
Before felling or delimbing for the first time, prac-
tise sawing logs on the ground or on trestles, so
that you can get familiar with the machine and
the most suitable sawing techniques.
Never work with the

machine must always be firmly held in both
hands, with the right hand on the front hand-
grip and the left hand on the rear handgrip,
even if the operator is left-handed.
WARNING!
ately if the chain stops during sawing.
Beware of kickback, which can occur if the
bar contacts an obstacle.
Kickback occurs when the tip of the chain
comes in contact with an object or when the
wood contracts and jams the chain during
sawing.
This contact with the tip of the chain can
cause a rapid backward motion, pushing the
guide bar up and towards the operator. This
also happens when the chain is jammed
along the upper part of the bar. In both cases,
kickback can cause the operator to lose con-
trol of the chain-saw, leading to serious con-
sequences.
• Delimbing (Fig. 13)
WARNING!
ing or nobody in the area where the branches
will fall.
1. Stand opposite the branch you want to cut.
2. Start cutting lower branches followed by the
higher ones.
3. Cut downwards to prevent the bar from get-
ting jammed.
• Felling (Fig. 14)
WARNING!
always stand uphill from the tree and check
that the felled trunk cannot cause damage if
it rolls down the hill.
1. Decide where the tree should fall – you
should consider the wind, the natural lean of
the tree, the position of the heaviest branch-
es and how easy the work is after felling, etc.
2. Clear the area around the tree and find a sta-
ble place to stand.
3. Plan obstacle-free escape routes at a 45°
