ASSEMBLY PROCEDURES

WARNING
Never try to start engine without side case, guide bar and chain
securely fastened.
1. Pull the front hand guard (2) toward the front handle to check that
the chain brake is disengaged. (Fig. 2)
2. Remove guide bar clamp nuts (3). Remove the side case (4).
(Fig. 3)
* In case of installing the spiked bumper (5), install the spiked
bumper (5) (if so equipped) to the unit with two screws. (Fig. 4)
3. Install the guide bar (6) onto the bolts (7), then push it toward the
sprocket (8) as far as it will go. (Fig. 5)
4. Confi rm the direction of saw chain (9) is correct as in the fi gure,
and align the chain on the sprocket (8). (Fig. 5)
5. Guide the chain drive links into the bar groove all around the
guide bar.
6. Install the side case (4) onto the bolts (7).
Make sure that the boss of chain tension adjust bolt (10) fi ts into
the hole of the guide bar (11). (Fig. 5)
Then tighten the guide bar clamp nuts (3) by hand that allows the
guide bar end to move up and down easily. (Fig. 6)
7. Raise the guide bar end, and tighten the chain (9) by turning the
tension adjustment bolt (12) clockwise. To check proper tension,
lightly lift up the center of chain and there should be about 0.5 –
1.0 mm clearance between guide bar and edge of drive link (13).
(Fig. 7, 8)
CAUTION
PROPER TENSION IS EXTREMELY IMPORTANT
8. Raise the guide bar end and securely tighten the guide bar
clamp nuts (3) with the combi box spanner (14). (Fig. 9)
9. A new chain will stretch so adjust the chain after a few cuts and
watch chain tension carefully for the fi rst half hour of cutting.
NOTE
Check the chain tension frequently for optimum performance
and durability.
CAUTION
○ When the chain is excessively tightened, the guide bar and
chain will be damaged rapidly. Conversely, when the chain is
excessively loosened, it may get out of the groove in the guide
bar.
○ Always wear gloves when touching the chain.
WARNING
During operation, hold chain saw fi rmly with both hands. A single
hand operation may cause serious injury.

OPERATING PROCEDURES

Fuel (Fig. 10)
WARNING
○ The chain saw 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 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 the oil bottle for the ratio or 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 (Fig. 11)
WARNING
○ Always shut off 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 (15), when fi lling up with fuel, so that
possible overpressure 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 leaking after refueling.
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.
Chain oil (Fig. 11)
WARNING
Never use waste or regenerated oil. If you use them, it will cause
damage to your health or this unit.
Slowly open the oil tank (16), and fi ll up with chain oil. Always use
high quality chain oil. When the engine is running, the chain oil is
automatically discharged.
Fill up the oil tank (16) with chain oil every time when refueling.
NOTE
When pouring fuel or chain oil into the tank, place the unit with
cap side up. (Fig. 11)
Chain brake operation (Fig. 2, 13)
Chain brake is designed to activate in an emergency such as kick-
back action.
Application of brake is made by moving the front hand guard (2)
towards the guide bar. During the chain brake operation, even if
the throttle lever is pulled, the engine speed does not increase and
the chain does not turn. To release the brake, pull up the front hand
guard toward the front handle.
If the engine keeps rotating at high speed with the brake engaged,
the clutch will overheat causing trouble.
When the brake engages during operation, immediately release the
throttle lever to slow down the engine.
How to confi rm the activation of the chain brake (Fig. 12)
1) Turn off the engine.
2) Holding the chain saw horizontally, release your hand from the
front handle, hit the tip of the guide bar to a stump or a piece
of wood, and confi rm brake operation. Operating level varies by
bar size.
In case the brake is not eff ective, ask Hitachi Authorized Service
Centers for inspection and repairs.
Starting the cold engine (Fig. 2, 13-17)
CAUTION
Before starting, make sure that the guide bar/chain does not
touch anything.
1. Push the front hand guard (2) so that the brake is engaged.
(Fig. 13)
2. Set stop switch (17) to ON position. (Fig. 14)
3. Push priming pump (19) approximately ten times so that fuel
fl ows bulb into carburetor. (Fig. 15)
4. Pull the choke lever (18) fully to set it in the START position.
(Fig. 15) This will automatically lock to half-throttle.
5. Pull recoil starter (20) rapidly, taking care to keep the handle in
your grasp and not allowing the handle to snap back. (Fig. 16)
6. When you hear fi rst ignition, push the choke lever (18) fully to set
it in the RUN position. (Fig. 15)
