WARNING
For Hitachi heads, use only flexible, non-metallic line
recommended by the manufacturer. Never use wire or wire
ropes. They can break oﬀ and become a dangerous projectile.

OPERATING PROCEDURES
Fuel (Fig. 20)
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 contains highly flammable and it is possible to get the
serious personal injury 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 the oil bottle for the ratio or Hitachi dealer.
○ 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.
○ Always mix fuel and oil in a separate clean container.
Always start by filing 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.

Cutting (Fig. 26, 27, 28)
○ When cutting, operate engine at over 6500 rpm. Extended time
of use at low rpm may wear out the clutch prematurely.
○ Cut grass from right to left.
○ Cut grass from left to right (only curve shaft model).
○ Blade thrust may occur when the spinning blade contacts a
solid object in the critical area.
A dangerous reaction may occur causing the entire unit and
operator to be thrust violently. This reaction is called blade
thrust. As a result, the operator may lose control of the unit
which may cause serious or fatal injury. Blade thrust is more
likely to occur in areas where it is diﬃcult to see the material to
be cut.
○ Wear the harness as shown in the figure (if so equipped). The
blade turns counter-clockwise, therefore, be advised to operate
the unit from right to left for eﬃcient cutting. Keep onlookers out
of working area at least 15 m.
NOTE
Press the quick release button or pull emergency release flap
(If so equipped) in the event of emergency. (Fig. 27-1)
WARNING
If cutting attachment should strike against stones or other
debris, stop the engine and make sure that the attachment and
related parts are undamaged. When grass or vines wrap around
attachment, stop engine and attachment and remove them.
Stopping (Fig. 29, 30)
Decrease engine speed and run at an idle for a few minutes, then
turn oﬀ ignition switch (24).
For models with an engine ignition switch, keep the ignition switch
pressed until the engine comes to a complete stop.

Carburetor adjustment (Fig. 31)
WARNING
The cutting attachment may be spinning during carburetor
adjustments.
○ Never start the engine without the complete clutch cover and
tube assembled! Otherwise the clutch can come loose and
cause personal injuries.
In the carburetor, fuel is mixed with air. When the engine is test
run at the factory, the carburetor is basically adjusted. A further
adjustment may be required, according to climate and altitude. The
carburetor has one adjustment possibility:
T = Idle speed adjustment screw.

Idle speed adjustment (T)
Check that the air filter is clean. When the idle speed is correct, the
cutting attachment will not rotate. If adjustment is required, close
(clockwise) the T-screw, with the engine running, until the cutting
attachment starts to rotate. Open (counter-clockwise) the screw
until the cutting attachment stops. You have reached the correct idle
speed when the engine runs smoothly in all positions well below the
rpm when the cutting attachment starts to rotate.

Flexible drive shaft (Fig. 35)
Flexible drive shaft should be removed and lubricated with good
quality lithium grease every 20 hours. To remove the flexible shaft,
first remove screw (29), loosen bolt (30) and remove the gear case
then pull the shaft out of the drive shaft pipe. Clean the shaft oﬀ and
apply a generous coat of lithium grease to it and insert if back into
the drive shaft pipe, turn it unit it drops into place then install the
gear case, install & tighten screw (29) and screw (30).

If the cutting attachment still rotates after idle speed adjustment,
contact your Hitachi dealer.

Angle transmission (Fig. 36)
Check angle transmission or angle gear for grease level about every
50 hours of operation by removing the grease filler plug on the side
of angle transmission.
If no grease can be seen on the flanks of the gears, fill the
transmission with quality lithium based multipurpose grease up to
3/4. Do not completely fill the transmission.

NOTE
○ Standard Idle rpm is 2800-3200 rpm.
WARNING
When the engine is idling the cutting attachment must under no
circumstances rotate.
Air filter (Fig. 32)
The air filter must be cleaned from dust and dirt in order to avoid:
○ Carburetor malfunctions
○ Starting problems
○ Engine power reduction
○ Unnecessary wear on the engine parts
○ Abnormal fuel consumption
Clean the air filter daily or more often if working in exceptionally
dusty areas.
Cleaning the air filter
Open the air filter cover and the filter (28). Rinse it in warm soap
suds. Check that the filter is dry before reassembly. An air filter
that has been used for some time cannot be cleaned completely.
Therefore, it must regularly be replaced with a new one. A damaged
filter must always be replaced.
Fuel filter (Fig. 33)
Drain all fuel from fuel tank and pull fuel filter line from tank. Pull
filter element out of holder assembly and rinse element in warm
water with detergent.
Rinse thoroughly until all traces of detergent are eliminated.
Squeeze, do not wring, away excess water and allow element to air
dry.
NOTE
If element is hard due to excessive dirt buildup, replace it.
Spark plug (Fig. 34)
The spark plug condition is influenced by:
○ An incorrect carburetor setting
○ Wrong fuel mixture (too much oil in the gasoline)
○ A dirty air filter
○ Hard running conditions (such as cold weather)
These factors cause deposits on the spark plug electrodes, which
may result in malfunction and starting diﬃculties. If the engine
is low on power, diﬃcult to start or runs poorly at idling speed,
always check the spark plug first. If the spark plug is dirty, clean it
and check the electrode gap. Re-adjust if necessary. The correct
gap is 0.6 mm. The spark plug should be replaced after about 100
operation hours or earlier if the electrodes are badly eroded.
NOTE
In some areas, local law requires using a resistor spark plug
to suppress ignition signals. If this machine was originally
equipped with resistor spark plug, use same type of spark plug
for replacement.

Semi-auto cutting head
Nylon line replacement
(1) Remove the case (31) by firmly pushing inward the locking tabs
with your thumbs as shown in Fig. 37.
(2) After removing the case, take out the reel and discard the
remaining line.
(3) Fold the new nylon line unevenly in half as shown in picture.
Hook the U-shaped end of the nylon line into the groove (32) on
the center partition of the reel.
Wind both halves of the line on the reel in the same direction,
keeping each half of the line on its own side of the partition.
(Fig. 38)
(4) Push each line into the stopper holes (33), leaving the loose
ends approx. 10 cm in length. (Fig. 39)
(5) Insert both loose ends of the line through the cord guide (34)
when placing the reel in the case. (Fig. 40)
NOTE
When placing a reel in the case, try to line up the stopper holes
(33) with the cord guide (34) for easier line release later.
(6) Place the cover over the case so that the cap locking tabs (35)
on the case meet the long holes (36) on the cover. Then push
the case securely until it clicks into place. (Fig. 41)
(7) The initial cutting line length should be approx. 11–14 cm and
should be equal on both sides. (Fig. 42)
Blade (Fig. 43)
WARNING
Wear protective gloves
maintenance on the blade.

when

handling

performing

Use a sharp blade. A dull blade is more likely to snag and thrust.
Replace the fastening nut if it is damaged and hard to tighten.
When replacing blade, purchase one recommended by Hitachi,
with a 25.4 mm (one inch) fitting hole.
When installing a saw blade (38), always face the stamped side
up. In the case of a 3 or 4 tooth blade (37), it can be used on
either side.
Use the correct blade for the type of work.
When replacing blades, use appropriate tools.
When cutting edges become dull, re-sharpen or file as shown
in the illustration. Incorrect sharpening may cause excessive
vibration.
Discard blades that are bent, warped, cracked, broken or
damaged in any way.

NOTE
When sharpening blade it is important to maintain an original
shape of radius at the base of the tooth to avoid cracking.
Maintenance schedule
Below you will find some general maintenance instructions. For
further information please contact your Hitachi dealer.

Daily maintenance
○ Clean the exterior of the unit.
○ Check that the harness is undamaged.
○ Check the blade guard for damage or cracks. Change the guard
in case of impacts or cracks.
○ Check that the cutting attachment is properly centred, sharp,
and without cracks. An oﬀ-centre cutting attachment induces
heavy vibrations that may damage the unit.
○ Check that the cutting attachment nut is suﬃciently tightened.
○ Make sure that the blade transport guard is undamaged and
that it can be securely fitted.
○ Check that nuts and screws are suﬃciently tightened.
Weekly maintenance
○ Check the starter, especially the cord and return spring.
○ Clean the exterior of the spark plug.
○ Remove it and check the electrode gap. Adjust it to 0.6 mm, or
change the spark plug.
○ Check that the angle gear is filled with grease up to 3/4.
○ Clean the air filter.
Monthly maintenance
○ Rinse the fuel tank with gasoline.
○ Clean the exterior of the carburetor and the space around it.
○ Clean the fan and the space around it.
