Installation of cutting blade (Fig.1-10,10B)
(If so equipped)
When installing a cutting blade, make sure that
there are no cracks or any damage in it and that
the cutting edges are facing the correct direction.
NOTE!
When installing cutter holder cap (1), be sure to
set concave side upward.
Insert the allen wrench (2) into the hole of the
angle transmission in order to lock the cutter
holder (3). Please note that the cutter fixing bolt
or nut (4) has left-handed threads, (clockwise to
loosen/counter-clockwise to tighten). Tighten the
fixing bolt or nut with the box wrench.
NOTE!
If your unit is of a nut securing type and
equipped with a cotter pin, the blade must be
retained with a new cotter pin (5) each time
installed. (Fig. 1-10C)
CAUTION!
Before operation, make sure the blade has been
properly installed.
CAUTION!
If your unit is equipped with protection cover
under a cutting blade, check it for wear or cracks
before operation. If any damage or wear is found,
replace it, as it is an article of consumption.

Fuel (Fig. 2-1)
WARNING!
The trimmer is equipped with a two-stroke
engine. Always run the engine on fuel,
which is mixed with oil.
Provide good ventilation, when fueling or
handling fuel.
Fuel
Always use branded 89 octane unleaded
gasoline.
Use genuine two-cycle oil or use a mix
between 25:1 to 50:1, please consult the oil
bottle for the ratio or Tanaka dealer.
Only for the state of California at 50:1.
If genuine oil is not available, use an anti-
oxidant added quality oil expressly labeled for
air-cooled 2-cycle engine use(JASO FC
GRADE OIL or ISO EGC GRADE). Do not use
BIA or TCW (2-stroke water-cooling type)

Always start by filling half the amount of fuel,
which is to be used. Then add the whole amount
of oil. Mix (shake) the fuel mixture. Add the
remaining amount of fuel.
Mix (shake) the fuel-mix thoroughly before filling
the fuel tank.
Fueling
WARNING!
Always shut off the engine before refueling.
Slowly open the fuel tank, when filling up
with fuel, so that possible over-pressure
disappears.
Tighten the fuel cap carefully, after fueling.
Always move the trimmer at least 3 m (10
ft.) from the fueling area before starting.
Before fueling, clean the tank cap area carefully,
to ensure that no dirt falls into the tank. Make sure
that the fuel is well mixed by shaking the container,
before fueling.
