spike (A, Fig. 34). The bucking spike is very sharp
and can cause injury. Be extremely careful when
working near the bucking spike.

Fueling (Do Not Smoke!) (Fig. 37)
This product is powered by a 2-cycle engine and requires pre-
mixing gasoline and 2-cycle oil. Pre-mix unleaded gasoline and 2-
cycle engine oil in a clean container approved for gasoline
(Fig.
35).

RATE ON UNLEADED GASOLINE INTENDED FOR AUTOMOTI-
VE USE WITH AN OCTANE RATING OF 89 ([R + M] / 2) OR
HIGHER
(Fig. 36).
Mix 2-Cycle Engine Oil with gasoline according to the instructions
on the package. If 2-Cycle Engine Oil is not available, use a high
quality 2-cycle engine oil for correct mixing proportion see table
below
(pag. 19).

When using an Oxygenated Gasoline a good practice of Fuel
Management is necessary.
Gasoline Oxygenated with alcohol readily takes/up water when it
is present; the water may be condensed out of humid air or be a
contaminant in the fuel system, including tank.
CAUTION:
- Match your fuel purchases to your consumption;
don’t buy more than you will use in one or two
months;
- Store gasoline in a tightly-closed container in a
cool, dry place.
The use of Oxygenated Gasoline may cause the occurrence of
vapor-lock easier.
