Checking The Chain Tension; Checking The Chain Brake; Checking The Machine - Hornbach CJ 300 Manual De Instrucciones

PREPARING TO WORK
– Never remove the fuel tank cap or add fuel
while the engine is running or still hot.
– Check for any leaks.
– Start the engine well away from the refuel­
ling point.
Before refuelling:
– S hake the fuel mixture container well.
– P lace the machine on a flat stable surface, with
the fuel tank cap facing upwards.
– C lean the fuel tank cap and the surrounding
area to avoid any dirt from entering the tank
during refilling.
– C arefully open the fuel tank cap to allow the
pressure inside to decrease gradually. Use a
funnel to refill and avoid filling the tank to the
brim.
WARNING!
cap firmly.
WARNING!
ces of fuel which may have dripped on the
machine or the ground and do not start the
engine until the petrol fumes have dissipated.
3. CHAIN LUBRICANT
IMPORTANT
Only use special oil for chain
saws or adhesive oil for chain saws. Do not use oil
containing impurities so as not to block the oil filter
and to prevent irreparable damage to the oil pump.
IMPORTANT
The special oil for lubricating
the chain is biodegradable. Use of a mineral oil or
engine oil causes serious damage to the environ­
ment.
It is essential that you use good quality oil to lu-
bricate the cutting parts effectively. Used or poor
quality oil does not guarantee good lubrication and
reduces the duration of the chain and bar.
It is always worth topping up the oil tank complete l y
(using a funnel) every time you refuel. Since the oil
tank capacity is enough to guarantee that the fuel
runs out first, you will avoid the risk of operating the
machine without lubricant.

4. CHECKING THE MACHINE

Before starting work please:
– c heck that the clutch functions properly (chain
does not move in idle)
– i nspect the chain-saw daily or before using, or
after being dropped to identify significant dam-
age or defects,
– fi ll the relevant tanks with fuel and oil;
– c heck that all the screws on the machine and the
Always close the fuel tank
Immediately clean all tra­
bar are tightly fastened;
– c heck that the chain is sharp and there are no
signs of any damage;
– c heck that the air filter is clean;
– c heck that handgrips and protection devices
are clean and dry, correctly mounted and well
fastened to the machine;
– c heck that the handgrips are well fastened;
– c heck that the chain brake is working efficiently;
– c heck the chain tension.

5. CHECKING THE CHAIN TENSION

WARNING!
with the engine off.
The tension is correct when the drive links do not
slip out of the chain guides if you hold the chain in
the middle of the bar (Fig. 7).
– Loosen the cover nut, using the supplied wrench
(Fig. 5).
– T urn the chain tension adjuster screw (4) to ad-
just the chain tension (Fig. 5).
– L ifting the bar, tighten the cover nut securely
using the supplied wrench (Fig. 6).

6. CHECKING THE CHAIN BRAKE

This machine is equipped with a safety brake sy-
stem.
The chain brake is a device which stops the chain
instantaneously if the chain saw recoils due to
kickback. Normally, the brake is activated auto-
matically by i n ertial force. It can also be activated
manually by pushing the brake lever (left-hand
guard) down toward the front.
This brake can be operated manually by pushing
the front guard forward. To release the brake, pull
the front guard towards the handgrip until you hear
a click.
To check that the brake works efficiently, proceed
as follows:
– 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 re-
lease the accelerator lever.
– Release the brake.
WARNING!
the chain brake does not function correctly
and have it inspected by your dealer.
