○
Fuel is highly
fl
ammable and it is possible to get seriously
injured when inhaling or spilling on your body.
Always pay attention when handling fuel. Always have
good ventilation when handling fuel inside building.
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 about the mixture ratio to Hitachi
Authorized Service Centers.
○
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) mixed oil.
○
Never use multi-grade oil (10 W/30) or waste oil.
○
Never mix fuel and oil in machine’s fuel tank. Always mix
fuel and oil in a separate clean container.
Always start by
fi
lling half the amount of gasoline, which is
to be used.
Then add the whole amount of oil. Mix (shake) the fuel
mixture. Add the remaining amount of gasoline.
Mix (shake) the fuel-mix thoroughly before
fi
lling the fuel
tank.

Fueling
WARNING
○
Always shut o
ff
the engine and let it cool for a few
minutes before refueling.
Do not smoke or bring
fl
ames or sparks near the fueling
site.
○
Slowly open the fuel tank, when
fi
lling up with fuel, so
that possible over-pressure disappears.
○
Tighten the fuel tank cap carefully, after fueling.
○
Always move the unit at least 3 m from the fueling area
before starting.
○
Always wash any spilled fuel from clothing immediately
with soap.
○
Be sure to check any fuel leakage after refueling.
○
Before fueling, in order to remove static electricity from
the main body, the fuel container and the operator,
please touch the ground that is slightly damp.
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.
Starting
WARNING
○
Before starting the tool, ensure that the cutting
attachment is not touching any objects or the ground.
Otherwise, the cutting attachment may unexpectedly
rotate and cause an injury.
○
Ensure that the cutting attachment does not rotate while
the engine is idling. If it does rotate, adjust the idle speed
according to the instructions in “Idle speed adjustment” in
the “MAINTENANCE” section. If the cutting attachment
still rotates after this adjustment, immediately stop the
engine and cease use, then bring the tool to the nearest
Hitachi Authorized Service Center.
CAUTION
For the CG24EC / CG27EC, ensure that the throttle
outer end is in the holder.
(1) Starting the cold engine
1. Set ignition switch (23) to ON position. (
Fig. 12
)
2. Push priming bulb (24) several times so that fuel
fl
ows
through return pipe (25). (
Fig. 13
)
3. Set choke lever (26) to START position (closed) (A).
(
Fig. 14
)
4. Pull recoil starter briskly, taking care to keep the handle
in your grasp and not allowing it to snap back. (
Fig. 15
)
5. When you hear the engine want to start, return choke
lever to RUN position (open) (B). (
Fig. 14
)
6. Pull recoil starter briskly again. (
Fig. 15
)
NOTE
If engine does not start, repeat procedures from 2 to 5.
7. Then allow the engine about 2–3 minutes to warm up
before subjecting it to any load.
8. Check that the cutting attachment does not rotate when
the engine is idling.
(2) Starting the warm engine
Use only 1, 2, 6 and 8 of the starting procedure for a cold
engine.
If the engine does not start, use the same starting
procedure as for a cold engine.
Cutting
WARNING
○
Always use the harness (if so equipped) and wear the
proper attire and protective equipment when operating
the unit. (
Fig. 16
)
○
Keep others including children, animals, bystanders and
helpers outside the 15 m hazard zone. Stop the engine
immediately if you are approached. (
Fig. 17
)
○
When grass or vines wrap around attachment, stop
engine and attachment and remove them. Continuing
operation with grass or vines wrapped around the
attachment may result in damages such as early
abrasion of the clutch.
CAUTION
Use and points of caution will vary depending on the type
of cutting attachment. For safe use, make sure to follow
the instructions and guidelines provided with each type.
NOTE
○
Press the quick release button or pull emergency release
fl
ap (If so equipped) in the event of emergency. (
Fig. 18
)
○
Use in accordance with local laws and regulations.
CG24ECM/CG27ECM only
●
Governor mechanism
The tool is equipped with a feature that keeps the engine
rotation speed consistent at the speed that is set. This
maintains a stable engine rotation speed even when the
burden applied to the tool bit becomes large, allowing for
steady operation.
However, if a burden larger than the tolerance is applied,
the engine rotation will decrease; in this case, adjust the
burden by decreasing the amount of material being cut.
The governor mechanism does not function when the
throttle is fully open.
Using a blade
○
Adjust engine speed according to the resistance of the
grass. For soft grass, use low speeds, For tough clumps
of grass, use high speeds.
○
Cut grass from right to left, using the left side of the blade
to cut. (
Fig. 19
)
○
Slightly tilting the blade to the left while cutting will pile
the cut grass to the left, making collection easy.
NOTE
Excessively increasing rotation speed may cause
increased blade wear, vibration and noise. It will also
result in increased fuel consumption.
