Before Starting The Equipment; Fuel And Lubrication - EINHELL GC-PC 2040 I Manual De Instrucciones

5. Before starting the equipment

Danger: Do not start the engine until the saw is
fully assembled.
Caution: Wear protective gloves at all times when
handling the chain.
5.1 Installing the guide rail and saw chain
(Fig. 2A-2G)
1. Disengage the chain brake by pushing the
front hand guard (6) towards the front handle
(7). (Fig. 2A)
2. Remove the guide rail cover (A) by loosening
the two nuts (19) (Fig. 2B).
3. Place the guide rail (2) into the mounting on
the chainsaw (Fig. 2C).
4. Place the chain (3) around the drive wheel (C)
(Fig. 2E). Check that the direction of rotation
of the chain (3) is correct. The cutter links (B)
must be aligned as shown in Fig. 2D.
5. Place the chain around the chain bar. (Fig.
2E)
6. The chain drive links (3) must slide fully into
the groove which runs around the cutter bar
(D) and also between the teeth on the drive
wheel (C). (Fig. 2E)
7. Turn the chain tensioning screw (20) counter-
clockwise until the bolt (E) is at the end of its
travel. (Fig. 1B/2F)
8. Install the bar cover (A).
Important! The bolt (E) on the chain tensioning
mechanism must snap into place in the hole (G)
in the guide rail. (Fig. 2G)
To ensure that happens, slide the guide rail (2)
forwards and backwards slightly when you mount
the bar cover (A). Hand tighten the nut (19).
5.2 Adjusting the chain tension (3A/3B)
Before adjusting the chain tension, make sure
that the engine is switched off .
1. Push the tip of the guide rail (2) upwards
slightly and adjust the chain tension using
the chain tensioning screw (20). (Fig. 3A) The
chain is set to the optimal tension when the
chain (3) on the underside at the middle of
the guide rail (2) is as shown in Fig. 3B (B).
2. Tighten the nut (19) while applying slight
pressure to the tip of the bar.
3. Carry out a functional check. Pull the chain
(3) by hand once all the way around the guide
rail (2). If the chain (3) is hard to pull around
the guide rail (2) or if it jams, the tension is too
tight.

If that is the case, make the following slight ad-
justment:
1. Loosen the nut (19) and hand tighten it again.
2. Reduce the chain tension by turning the chain
3. If the chain tension is adjusted to the optimal
A new saw chain will stretch, so it is impor-
tant to readjust the chain at short intervals
(around 5 cuts) when you fi rst start using it.
The intervals get longer as operating time
increases.
Note: If the saw chain (3) is TOO LOOSE or TOO
TAUT, the drive wheel, chain bar, chain and crank
shaft bearing will suff er premature wear. Fig. 3B
shows the correct tension A (when cold) and ten-
sion B (when warm). Fig. C shows a chain that is
too loose.

5.3 Fuel and lubrication

Fuel
Use regular grade unleaded gasoline mixed with
1:40 custom 2-cycle engine oil for best results.
Mixing fuel
Mix fuel with 2 cycle oil in an approved container.
Shake container to ensure thorough mix.
Note: Never use straight gasoline in your unit.
This will cause permanent engine damage and
void the manufacturer's warranty for that product.
Never use a fuel mixture that has been stored for
over 90 days.
Note: If 2-cycle lubricant is to be used, it must be
a premium grade oil for 2-cycle air cooled engi-
nes mixed at a 1:40 ratio. Do not use any 2-cycle
oil product with a recommended mixing ratio of
1:100. If insuffi cient lubrication is the cause of en-
gine damage, it voids the manufacturer's engine
warranty for that occurrence.

tensioning screw (20) counterclockwise. Only
make small adjustments at a time and always
pull the chain (3) backwards and forwards on
the guide rail (2) to see if the chain (3) moves
smoothly but still fi ts tightly.
Note: If the chain (3) is too loose, turn the
chain tensioning screw (20) clockwise.
