Recommended cutting procedure.
Warning!
1. Beware of kick back.
2. Do not attempt to hold saw with one
hand.
3. Avoid bar nose contact.
Recommended
4. Hold saw properly with both hands.
Never use the machine with one hand:
the chain brake does not work!
Danger! Beware of kickback!
Warning! Kickback can lead to dangerous loss of control of the chain saw and
result in serious or fatal injury to the saw operator or to anyone standing close by.
Always be alert because rotational kickback and pinch kickback are major chain
saw operational dangers and the leading cause of most accidents.

until it appears at the outside edge of the sprocket tip (Fig.14).
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. 15)
3.
Reinstall the bar, chain (and adjust tension) and sprocket cover.
(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.
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 or stiff brush.
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.
