4. Controlling that the chain brake functions correctly.
5. Controlling the stoppage of the chain when the start lever is
released.
These operations are described individually below:
1. Starting the electric chain saw
- Check that the chain brake is deactivated, pulling back (towards the
motor) the front hand guard (nr. 8).
- Hold the saw firmly with both hands when running, with your right
hand on the rear hand grip (nr. 2 Fig. A) and the left hand on the
front hand grip (nr. 7 Fig. A).
- Turn on the chain saw by pushing the release button (nr. 5) first and
then pulling the start lever (nr. 4).
Note: once the chain saw is running, it is not necessary to hold
down the release button.
The release button (nr. 5) is a safety device that prevents accidental
starts.
2. Stopping the electric chain saw
- The chain saw stops automatically when the start lever (nr. 4) is
released.
3. Controlling that the automatic oiler functions correctly
Introduction:
- Check that the tank is full of oil.
- Turn on the chain saw over a sheet of cardboard holding the blade
about 4 cm away.
- If an oil stain forms on the cardboard within a minute, the lubrication
device is working correctly. If there is no oil on the cardboard, read
the "Troubleshooting" paragraph.
4. Controlling that the chain brake functions correctly.
Introduction:
The chain brake is a safety device that is activated by exerting pressure
against the front hand guard (nr.8 Fig. A) when, in case of a kickback,
the operator's hand hits the lever. When the chain brake is activated,
the movement of the chain is arrested within 0.15 seconds.
The purpose of the chain brake is to reduce danger in case of kickback.
Before using the chain saw, you must test the chain brake as follows:
- Check that the chain brake is deactivated, pulling the front hand
guard (nr. 8) back towards the motor.
- Position the chain saw on a solid flat surface that has been cleared
of all objects.
- Connect the chain saw to the power supply, take it in both hands,
and turn it on.
- While the chain saw is functioning, activate the chain brake by
pushing your left hand against the hand guard (nr.8).
- The chain should stop instantly.
N.B. Release the start lever immediately.
- IMPORTANT! If the chain does not stop when the brake is activated,
have the chain saw checked at an authorised customer service
centre.Do not use the chain saw if the chain brake does not function
properly!
SHARPENING THE CHAIN
- Bring the chain to a specialized workshop for maintenance.
- IMPORTANT! If the chain is not sharpened regularly, the risk of
kickback is increased.
FELLING TREES AND SAFETY PROCEDURES
The following topics will be discussed below:
1. Advice for those using the chain saw for the first time
2. Useful suggestions concerning safety gear
3. Limiting access to danger zones
4. Precautions to be taken according to weather conditions for people
in the area and eventual local regulations.
5. Preparing and using escape routes
6. Felling trees on slopes
7. Felling trees in relation to the saw's cutting capacity.
8. How to control the fall direction of the tree being cut.
9. Using wedges for felling trees
10. Cutting branches (debranching)
11. Cutting fallen trunks
12. Cutting wood on supports
1. Advice for those using the chain saw for the first time
Those who are using the chain saw for the first time should receive
practical instructions concerning its use and gear by an expert ope-
rator. A beginner should first practice by cutting wood on a trestle
or other support.
2. Useful suggestions concerning safety gear
For protection from other risks related to the use of this tool, adequate
clothing and gear must be used. In general, the following devices
should be used:
- Heavy-duty padded trousers.
- Coloured jacket to ensure that the operator is easily visible.
- Heavy-duty leggings and heavy-duty, safety shoes with non-skid soles
and steel toes.
- Heavy-duty gloves and, if possible, insulated to dampen vibrations.
- Helmet with visor for protection from falling branches and materials.
- Soundproof headphones to protect hearing.
3. Limiting access to danger zones
Limit access to the area by marking it off with warning signs.
4. Precautions to be taken according to weather conditions for
people in the area and eventual local regulations.
- IMPORTANT! Do not use the chain saw in adverse weather condi-
tions: rain, snow, low visibility, near cables or electrical networks, or
where there may be a risk of explosions.
- Never cut in the presence of people or animals and keep at a distance
twice the height of the tree.
- Find out about any restrictions on forest cutting issued by institu-
tions, municipal ...
5. Preparing and using escape routes (see also point 6)
- IMPORTANT! Before you begin felling a tree, you must decide
the fall direction, identify the escape route and then eliminate all
obstacles along it.
N.B.: The direction of the fall is determined by the cut.
- The escape routes for the operator are outlined in figure below.
a) Fall direction
b) Danger area
c) Escape route
6. Felling trees on slopes
- IMPORTANT! When felling a tree on a slope, the operator must
position himself on the upper side because, once the tree is cut, it
will roll downhill.
stazionate sul lato alto quando tagliate
perchè il tronco può rotolare
stand on uphill when cutting because
log may roll
