Stopping The Engine; Use - EMAK MTT 2500 Manuel D'utilisation Et D'entretien

BREAKING-IN THE CHAIN
New chains will stretch and must be tightened
frequently. Tension adjustment should only be
made when the chain is cool. First, turn the chain
and lubricate it with additional oil. Then start
the saw and allow it to run at moderate speed,
checking that the oil pump is working properly.
Stop the engine and adjust the chain tension.
Start the saw again and make a few cuts in a
trunk to heat up the chain. Stop the engine, allow
the chain to cool and adjust again. Repeat this
process until the chain retains proper tension. Do
not touch the ground with the chain.
WARNING - Never touch the chain while
the motor is running. Do not touch the
ground with the chain.

6. STOPPING THE ENGINE

Release the throttle lever (2, Fig. 2) and let
the engine return to idle. Turn off the engine,
pushing the STOP button (10).
Do not put the chain saw on the ground
when the chain is still moving.

7. USE

Long term inhalation of the engine's exhaust
fumes, chain oil mist and dust from sawdust can
represent a health risk.
CHAIN BRAKE
The inertial chain brake ensures maximum
safety in using the chainsaw. It protects the
operator from dangerous kickback which can
occur during working phases. It is actuated, with
consequent instant locking of the chain, when
the operator presses the lever (manual operation)
or automatically by inertia when the protection is
pushed forward (Fig. 15) in the event of sudden
kickback (inertial operation).
The chain brake is released by pulling the lever
towards the operator (Fig. 3).
CHECKING BRAKE OPERATION
At machine inspection prior to each job, check
the operating condition of the brake following
the steps below:
1. Start the engine and grasp the handle
securely with both hands.
2. Pulling the throttle lever to maintain the chain
operation, push the brake lever down toward
the front using the back of your left hand
(Fig. 11).
3. When the brake operates and the chain is
stopped, release the throttle lever.
4. Release the brake (Fig. 3).
BRAKE MAINTENANCE: always keep the
chain brake mechanism clean and lubricate
the leverage. Check wear on the brake belt. Its
minimum thickness must be 0.30 mm.
WORKING WITH TREE SERVICE CHAIN-SAWS
FROM A ROPE AND HARNESS
This chapter sets out working practices to reduce
the risk of injury from tree service chainsaws
when working at height from a rope and harness.
While it may form the basis of guidance and
training literature, it should not be regarded as a
substitute for formal training.
General requirements working at height
Operators of tree service chainsaws working at
height from a rope and harness should never
work alone. A competent ground worker trained
in appropriate emergency procedures should
assist them.
Operators of tree service chainsaws for this work
should be trained in general safe climbing and
work positioning techniques and shall properly
equipped with harnesses, ropes, strops,
karabiners and other equipment for maintaining
secure and safe working positions for both
themselves and the saw.
