Maintaining The Guide Bar - Remington RM2599 Manuel De L'utilisateur

MAINTAINING THE GUIDE BAR

1. Rotate the guide bar frequently, at regular intervals (for example,
after every 5 hours of operation), to ensure even wear on the top
and bottom of the guide bar.
2. Clean the guide bar groove and oil passages whenever the saw
chain is removed, when the unit has been used heavily or when
the saw chain appears dirty. Use a screwdriver, putty knife, wire
brush or similar instrument to remove debris from the guide bar
groove (Fig. 16). Use a soft wire that is small enough to insert
into the chain oil discharge hole to remove any debris from the
hole (Fig. 17).
3. Frequently check the guide bar for damage. Feathering and
burring of the guide bar rails (the ridges on either side of the bar
groove) is a normal process of guide bar wear. Such faults
should be smoothed with a file as soon as they occur. A guide
bar with the following faults should be replaced:
• Wear inside the guide bar rails that permits the chain to lay
sideways
• Bent guide bar
• Cracked or broken rails
• Spread rails
MAINTAINING THE SAW CHAIN
WARNING:
Unless you have experience and specialized
training for dealing with kickback (refer to the Safety
section), 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.
The saw chain will wear with use, causing the chain to stretch. This
is normal. When it is no longer possible to obtain a correct chain
tension adjustment, the saw chain will need to be repaired by an
authorized service dealer or replaced.
Always use a replacement saw chain designated as "low-kickback"
or a saw chain that meets the low-kickback performance
requirements. A standard saw chain (a chain that does not have the
kickback-reducing guard links) should only be used by an
experienced professional chain saw operator.
