Fuel Handling; Starting And Stopping - Gardol GMSH50 Manual De Instrucciones

8. If chain is too loose, it will sag below the guide bar.
DO NOT operate the saw if the chain is loose.
Note: The chain is tensioned correctly when the
weight of the chain does not cause it to sag below
the guide bar (with the chain saw sitting in an
upright position), but the chain still moves freely
around the guide bar.
Fueling engine
a WARNING: Remove fuel cap slowly when
refueling.
Important: This equipment is designed to operate on
unleaded petrol with a minimum 90 octane (ROM),
with ethanol blended up to 10% maximum by volume
(E-10). Before operation, petrol must be mixed with
a good quality synthetic 2-cycle air-cooled engine oil
designed to be mixed at a ratio of 50:1.
Do not use automotive oil or marine oil. These oils
will cause engine damage. When mixing fuel, follow
instructions printed on container. Once oil is added to
petrol, shake container momentarily to assure that the
fuel is thoroughly mixed. Always read and follow the
safety rules relating to fuel before fueling your unit.
Purchase fuel in quantities that can be used within 30
days to assure fuel freshness.
Caution: Never use straight petrol in your unit. This
will cause permanent engine damage and void the
limited warranty. Do not use alternate fuels such as
ethanol blends above 10% by volume (E-15, E-85)
or any methanol blended fuel. Use of these fuels
can cause major engine performance and durability
problems.
Chain brake
Ensure chain brake is unlocked by pulling the front
hand guard back toward the front handle as far as
possible. The chain brake must be unlocked before
cutting with the saw.
a WARNING: The chain must not move when
the engine runs at idle speed. If the chain
moves at idle speed refer to CARBURETTOR
ADJUSTMENT within this manual.
a WARNING: Avoid contact with the muffler. A
hot muffler can cause serious burns.
To stop the engine move the ON/STOP switch to the
STOP position.
To start the engine hold the saw firmly on the ground
as illustrated. Make sure the chain is free to turn
without contacting any object.

Starting and stopping

a WARNING: If the saw is operated with
a loose chain, the chain could jump off
the guide bar and result in serious injury
to the operator and/or damage the chain
making it unusable. If the chain jumps off
the guide bar, inspect each drive link for
damage. Damaged chain must be repaired
or replaced.

Bar and chain lubrication
The bar and chain require continuous lubrication.
Lubrication is provided by the automatic oiler system
when the oil tank is kept filled. Lack of oil will quickly
ruin the bar and chain.
Too little oil will cause overheating shown by smoke
coming from the chain and/or discoloration of the
bar. In freezing weather oil will thicken, making it
necessary to thin bar and chain oil with a small
amount (5 to 10%) of #1 Diesel Fuel or kerosene. Bar
and chain oil must be free flowing for the oil system to
pump enough oil for adequate lubrication.
Bar and chain oil is recommended to protect your unit
against excessive wear from heat and friction. If bar
and chain oil is not available, use a good grade SAE
30 oil.
• Never use waste oil for bar and chain lubrication.
• Always stop the engine before removing the oil cap.
a WARNING: Do not attempt to throw or drop-
start the chain saw. Doing so will put the
operator at risk of serious injury due to loss
of control of the chain saw.
Important: When pulling the starter rope, do not
use the full extent of the rope as this can cause the
rope to break. Do not let starter rope snap back.
Hold the handle and let the rope rewind slowly.
