STORINg THE PRODUCT
See Figure 30.
 Clean all foreign material from the product. Store idle unit
indoors in a dry, well-ventilated area that is inaccessible
to children. Keep away from corrosive agents such as
garden chemicals and de-icing salts.
 Abide by all ISO and local regulations for the safe storage
and handling of gasoline.
 Always place the scabbard on the saw bar when trans-
porting or storing the pruner. The scabbard is a snug fit
and must be attached very carefully due to the sharp
teeth on the saw chain. This is best done by grasping the
scabbard at one end, in the center portion of the scab-
bard, and carefully sliding it over the chain as shown. Use
caution to avoid the sharp teeth of the chain.
NOTE: The saw chain is very sharp. Always wear protec-
tive gloves when handling the chain.
 To use the hanger cap, push in the button and place the
hanger cap over end of the lower end attachment shaft.
Slightly rotate the cap from side to side until the button
locks into place.
When storing 1 month or longer:
 Drain all fuel from tank into a container approved for
gasoline. Run engine until it stops.
