Adjusting The Chain Tension - Echo CCS-58V Manuel D'utilisation

MAINTENANCE
 Remove the bar mounting nuts using the com-
bination wrench provided.
 Remove the chain cover.
 Remove the bar and chain from the mounting
surface.
 Remove the old chain from the bar.
 Lay out the new saw chain in a loop and
straighten any kinks. The cutters should face
in the direction of chain rotation. If they face
backwards, turn the loop over.
 Place the chain drive links into the bar groove as
shown.
NOTE: Make certain of direction of chain.
 Position the chain so there is a loop at the back
of the bar.
 Hold the chain in position on the bar and place
the loop around the sprocket.
 Fit the bar flush against the mounting surface
so that the bar studs are in the long slot of the
bar.
 Replace the chain cover ensuring that the ad-
justing pin in the chain cover is in the bar chain
tensioning pin hole and that both bar studs are
securely in their respective holes in the chain
cover.
NOTE: The adjusting pin may need to be slightly
repositioned with the chain tensioning screw
so that it is aligned with the position of the bar
chain tensioning pin hole.
 Replace the chain cover and bar mounting nuts.
 Finger-tighten the bar mounting nuts. The bar
must be free to move for tension adjustment.
 Remove all slack from the chain by turning the
chain tensioning screw clockwise until the chain
seats snugly against the bar with the drive links
in the bar groove.
 Lift the tip of the guide bar up to check for sag.
 Hold the tip of the guide bar up and tighten
the bar mounting nuts securely.
The chain is correctly tensioned when there is no
sag on the underside of the guide bar, the chain is
snug, but it can be turned by hand without binding.
