Chain Catcher - Husqvarna 420 EL Bedienungsanweisung

brake manually. This movement starts a spring-loaded
mechanism that stops the drive sprocket.
(Fig. 21)
How the chain brake is engaged is in relation to the
force of the kickback and position of the product. If
you get an intense kickback while the kickback zone is
farthest away from you, the chain brake engages by the
inertia release. If the kickback is small or the kickback
zone is nearer you, the chain brake engages manually
by your left hand.
(Fig. 22)
Use the chain brake as a parking brake when you
start the product and when you move short distances.
This decreases the risk that you or a person near you
touches the saw chain.
(Fig. 23)
Pull the front hand guard rearward to disengage the
chain brake.
(Fig. 24)
A kickback can be very sudden and intense. Most
kickbacks are small and do not always engage the chain
brake. If a kickback occurs when you use the product,
hold tightly around the handles and do not let go.
(Fig. 25)
The front hand guard also decreases the risk to touch
the saw chain if your hand lets go of the front handle.
(Fig. 26)
In the felling position you cannot engage the chain brake
manually. The chain brake can in this position only be
engaged by the inertia release mechanism.
(Fig. 27)
Power trigger lockout
The power trigger lockout prevents accidental operation
of the power trigger. If you put your hand around
the handle and press the power trigger lockout (A), it
releases the power trigger (B). If you release the handle,
the power trigger and the power trigger lockout move
back to their initial positions.

Chain catcher

The chain catcher catches the saw chain if it breaks or
comes loose. If you have the correct chain tension, the
risk decreases. You also decrease the risk if you do the
90
correct maintenance on the guide bar and saw chain.

Right hand guard
The right hand guard works as a protection for your
hand if the saw chain breaks or comes loose. It also
prevents interference from branches and twigs when
you use the product.

Safety instructions for the cutting
equipment
WARNING:
instructions that follow before you use the
product.
• Only use approved guide bar/saw chain
combinations and filing equipment. Refer to
Technical data on page 99 for instructions.
• Use protective gloves when you use or do
maintenance on the saw chain. A saw chain that
does not move can also cause injuries.
• Keep the cutting teeth correctly sharpened. Obey the
instructions and use the recommended file gauge. A
saw chain that is damaged or incorrectly sharpened
increases the risk of accidents.
(Fig. 31)
• Keep the correct depth gauge setting. Obey the
instructions and use the recommended depth gauge
setting. Too large depth gauge setting increases the
risk of kickback.
(Fig. 32)
• Make sure that the saw chain has the correct
tension. If the saw chain is not tight against the
guide bar, the saw chain can derail. An incorrect saw
chain tension increases wear on the guide bar, saw
chain and chain drive sprocket. Refer to
the tension of the saw chain on page 98 .
(Fig. 33)
• Do maintenance on the cutting equipment regularly
and keep it correctly lubricated. If the saw chain is
not correctly lubricated, the risk of wear on the guide
bar, saw chain and chain drive sprocket increases.
