GUIDE BAR
- The bar should be reversed every 8 working hours to ensure uniform wear.
Keep the bar groove and lubrication hole clean using the bar groove cleaner supplied optional. (Fig. 7A)
Check the bar rails frequently for wear and, if necessary, remove the burs and square-up the rails using the flat file (Fig. 7B).
WARNING: Never mount a new chain on a worn sprocket or self-aligning ring.
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.
BAR GROOVES
- 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 1chain”, 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.
WARNING: Always wear protective gloves during maintenance operations. Do not carry out maintenance
when the engine is hot.
CHAIN SHARPENING
- The pitch of the chain (Fig. 8) is 3/8” LoPro x .050”.
Sharpen the chain using protective gloves and a round file of ø3/16” (4.8mm).
Always sharpen the cutters only with outward strokes (Fig.9) observing the values given in Fig. 8.
After sharpening, the cutting links must all have the same width and length.
