Guide Bar; Saw Chain - Ferax FKS-2000 Manual

GB
Proper maintenance of the guide bar, as explained
in this section, is essential to keep your saw in good
working order.
Sprocket tip lubrication
For units supplied with sprocket tip guide bars only.
Caution! Failure to lubricate the guide bar
sprocket tip as explained below will result in
poor performance and seizure, voiding the
manufacturer's warranty.
Lubrication of the sprocket tip is recommended after
each saw use. Always thoroughly clean the guide bar
sprocket tip before lubrication.
Warning! Wear heavy duty work gloves when
performing this application to reduce risk of
personal injury.
To Lubricate Sprocket Tip:
Fig. 15-16
1. Unplug the chain saw from the power source.
Note: It is not necessary to remove the saw chain to
lubricate the guide bar sprocket tip. Lubrication can be
done on the job.
2. Clean the guide bar sprocket tip.
3. Using disposable Lube gun, insert needle nose
into the lubrication hole and inject grease until it
appears at the outside edge of the sprocket tip
(Fig.15).
4. Make sure that the chain brake is deactivated.
Rotate the saw chain by hand. Repeat the
lubrication procedure until the entire sprocket tip
has been greased.
To Clean Guide Bar Rails
1. Remove sprocket cover, bar and chain.
2. Using a screwdriver, putty knife, wire brush
or other similar instrument, clear residue from
the rails on the guide bar. This will keep the oil
passages open to provide proper lubrication to the
bar and chain. (Fig. 16)
3. Reinstall the bar, chain (and adjust tension),
sprocket cover and bar bolt retaining nuts. (See
Section Guide bar / saw chain installation).
Guide bar maintenance
Most guide bar problems can be prevented merely
by keeping the chain saw well maintained. Incorrect
filing and non-uniform cutter and depth gauge settings
cause most guide bar problems, primarily resulting in
uneven bar wear.
As the bar wears unevenly, the rails widen, which may
cause chain clatter and difficulty in making straight
cuts. Insufficient guide bar lubrication and operating
the saw with a chain that is too tight will contribute
to rapid bar wear (see Section Chain maintenance
instructions). To help minimize bar wear, the following
guide bar maintenance is recommended.
14
Bar wear
Turn guide bar frequently at regular intervals (for
example, after 5 hours of use), to ensure even wear on
top and bottom of bar.
Bargrooves
Bar grooves (or rails which support and carry the chain)
should be cleaned if the saw has been heavily used or
if the saw chain appears dirty. Rails should always be
cleaned every time the saw chain is removed.
Oil passages
Oil passages at bar pad should be cleaned to
ensure proper lubrication of the bar and chain during
operation. This can be done using a soft wire small
enough to insert into the oil discharge hole.
Note: The condition of the oil passages can be easily
checked. If the passages are clear, the chain will
automatically give off a spray of oil within seconds
of starting the saw. Your saw is equipped with an
automatic oiler system.
Chain maintenance instructions
Warning! Unless you have experience and
specialized training for dealing with kickback
(see Safety Precautions), always use a low-
kickback saw chain, which significantly
reduces the danger of kickback. Low-
kickback saw chain does not completely
eliminate kickback. A low-kickback or "safety
chain", should never be regarded as total
protection against injury.
A low-kickback saw chain should always be used in
conjunction with other kickback protection devices
such as the chain brake / Hand Guard furnished
with your unit. Always use a replacement saw chain
designed as "low-kickback" or a saw chain which
meets the low-kickback performance. A standard
saw chain (a chain which does not have the kickback
reducing guard links) should only be used by an
experienced professional chain saw operator.
What is a Low-Kickback Saw Chain
A low-kickback saw chain is a chain which has met the
kickback performance requirements of ISO 9518.
By keeping the chain brake and saw chain in
good working condition and correctly serviced as
recommended in this manual, you will be able to
maintain the safety system of your chain saw over the
life of the product.
Warning! Never remove, modify or make
inoperative any safety device furnished with
your unit. The Chain Brake/Hand Guard and
low-kickback saw chain are major safety
features provided for your protection.
Warning! Always wear heavy duty protection
work gloves and disconnect the extension
cord when working on the saw chain.
