ASSEMBLY PROCEDURES
WARNING
Never try to start engine without side case, 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)
3. Install the guide bar (5) onto the bolts (6), then push it toward the
sprocket (7) as far as it will go.
4. Confi rm the direction of saw chain (12) is correct as in the fi gure,
and align the chain on the sprocket. (Fig. 5)
5. Guide the chain drive links into the bar groove all around the bar.
6. Install the side case (4) onto the bolts (6).
Make sure that the boss of chain tension adjust bolt (8) fi ts into
the hole (9) of the bar. (Fig. 4)
The brake lever (11) of the side case must fi t the groove (10) on
the side of the front hand guard.
Then tighten the guide bar clamp nuts (3) by hand that allows the
guide bar end to move up and down easily. (Fig. 3)
7. Raise the bar end, and tighten the chain (12) by turning the
tension adjustment bolt (13) clockwise. To check proper tension,
lightly lift up the center of chain and there should be about 0.5
– 1.0 mm clearance (14) between bar and edge of drive link.
(Fig. 6, 7)
CAUTION
PROPER TENSION IS EXTREMELY IMPORTANT
8. Raise the bar end and securely tighten the guide bar clamp nuts
with the combi box spanner. (Fig. 7)
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 bar and chain will
be damaged rapidly. Conversely, when the chain is excessively
loosened, it may get out of the groove in the 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. 8)
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 contains highly fl ammable 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 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.
○ 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 (Fig. 9)
○ Always shut off the engine before refueling.
○ Slowly open the fuel tank (15), when fi lling up with fuel, so that
possible overpressure disappears.
○ Tighten the fuel 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. 9)
Fill up with chain oil (16). Always use good quality chain oil. When the
engine is running, the chain oil is automatically discharged.
NOTE
When pouring fuel (15) or chain oil (16) into the tank, place the
unit with cap side up. (Fig. 9)
ADJUSTMENT OF CHAIN OIL SUPPLY
The chain oil quantity discharged through the lubrication system
is adjusted to the maximum in the factory. Adjust the quantity in
accordance with the operating condition.
Turn the adjusting screw (17) counterclockwise to increase the
quantity and turn it clockwise to decrease the quantity. (Fig. 10)
Chain brake operation (Fig. 2, 11)
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 towards
the 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 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
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 our dealer for inspection and
repairs.
Starting (Fig. 11 – 16)
CAUTION
Before starting, make sure chain brake is engaged and that the
bar/chain does not touch anything. (Fig. 11)
1. Set ignition switch (18) to ON position. (Fig. 12)
*Push priming pump (20) several times so that fuel fl ows through
bulb into carburetor. (Fig. 13)
2. Pull the choke lever (19) to choked position (Fig. 13).
This will automatically lock to the half-throttle .
3. Push the decompression valve (21).
The valve (21) will automatically return to the original position
once the engine has started (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 fi rst ignition, return the choke lever (19) all the
way in. (Fig. 13)
6. Push the decompression valve.
