WARNING
KICKBACK DANGER (Fig. 2)
One of the most severe dangers when working with a chain
saw is the possibility of kickback. Kickback may occur when
the upper tip of the guide bar touches an object, or when
the wood closes in and pinches the saw chain in the cut. Tip
contact in some cases may cause a lightning fast reverse
reaction, kicking the guide bar up and back toward you.
Pinching the saw chain along the top of the guide bar may
also push the guide bar rapidly back towards you. Either of
these reactions may cause you to lose control of the chain
saw which could result in serious personal injury. Even
though your chain saw has safety built into its design, you
should not rely on these safety features exclusively. Know
where your guide bar tip is at all times. Kickback does occur
if you allow the kickback zone (1) of the guide bar to touch
an object. Do not use that area. Kickback from pinching is
caused by a cut closing and pinching the upper side of the
guide bar. Study your cut and make sure it will open as you
cut through. Maintain control when the engine is running by
always keeping a fi rm grip on the chain saw with your right
hand on the rear handle, your left hand on the front handle
and your thumbs and fi ngers encircling the handles. Always
hold the chain saw with both hands during operation and cut
at high engine speed.
Follow manufacturer's
instructions for the saw chain. The lack of this maintenance
may increase the possibility of kickback.

ASSEMBLY PROCEDURES

WARNING
Switch off the engine before carrying out any checks or
maintenance.
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. 3)
2. Remove guide bar clamp nuts (3). Remove the side case
(4). (Fig. 4)
* In case of installing the spiked bumper (5), install the
spiked bumper (5) to the unit with two screws. (Fig. 5)
3. Install the guide bar (6) onto the bolts (7), then push it
toward the sprocket (8) as far as it will go. (Fig. 6)
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. 6)
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 (11) of the guide bar. (Fig. 6)
Then tighten the guide bar clamp nuts (3) by hand that

sharpening and maintenance
7. Raise the guide bar end, and tighten the chain (9) by
turning the tension adjustment bolt (12) clockwise until
the chain fi ts snugly against underside of guide bar (6).
The chain is correctly tensioned when there is no slack
on the underside of the guide bar. (Fig. 8, 9)
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.
10)
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.

OPERATING PROCEDURES

Fuel (Fig. 11)
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 about the mixture ratio to Tanaka
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.
○ 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.

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.
