OPERATING PROCEDURES

Operator safety
WARNING
This chain saw (CS33EDT) is designed especially for tree care and
surgery. Only persons trained in tree care and surgery may use
this saw. Observe all literature, procedures and recommendations
from the relevant professional organization. Failure to do so
constitutes a high accident risk. We recommend always using
a rising platform for sawing in trees. Rappelling techniques are
extremely dangerous and require special training. The operator
must be trained in and familiar with the use of safety equipment
and working and climbing techniques. Always use the restraining
equipment for both the operator and the saw.
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 HiKOKI 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.
○ 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 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 (13), 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. 9)
Slowly open the oil tank (14), and fi ll up with chain oil. Always use
good quality chain oil. When the engine is running, the chain oil is
automatically discharged.
Fill up the oil tank (14) with chain oil every time when refueling.
NOTE
When pouring fuel (13) or chain oil (14) into the tank, place the
unit with cap side up. (Fig. 9)
Starting the cold engine (Fig. 10-15)
CAUTION
Before starting, make sure that the bar/chain does not touch
anything.
1. Make sure chain brake is engaged. (Fig. 10)
2. Set ignition switch (15) to ON position (Fig. 11).
3. Push priming pump (16) about ten times so that fuel fl ows
through priming pump into carburetor. (Fig. 12)
4. Turn the choke lever (17) to choked position (Fig. 12). This will
automatically lock the throttle in starting position.
5. Pull recoil starter briskly, taking care to keep the handle in your
grasp and not allowing it to snap back. (Fig. 13)
6. When you hear fi rst ignition, return the choke lever to run
position. (Fig. 12)
7. Pull recoil starter briskly again in the aforementioned manner.
(Fig. 13)
NOTE
If engine does not start, repeat procedures from 4 to 7.
8. As soon as engine start, pull throttle trigger full once and release
immediately. (Fig. 14)
Then half-throttle is disengaged.
9. Make sure chain brake is disengaged. (Fig. 15)
Allow the engine about 2-3 minutes to warm up before subjecting
it to any load.
Do not run the engine at high speed without the load to shorten
the longevity of the engine.
Starting the warm engine
Use only 1, 2, 7, and 9 of the starting procedure for a cold engine.
If the engine does not start, use the same starting procedure as for
a cold engine.
Chain lubrication test
Check that chain oil is discharged properly. When the saw chain
starts to revolve, point the head of the guide bar to a stump, etc., and
pull the throttle trigger to perform high-speed operation for around
10 seconds. If chain oil is sprayed over the stump, it is discharged
properly. (Fig. 16)
Chain brake operation (Fig. 17)
Chain brake (18), is designed to activate in an emergency such as kick-
back action. Please check to verify that it works properly before use.
Application of brake is made by moving the front hand guard towards
the bar. During the chain brake operation, even if the throttle trigger
is pulled, the engine speed does not increase and the chain does not
turn. To release the brake, pull up the front hand guard.
How to confi rm:
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 HiKOKI Authorized Service
Centers for inspection and repairs. 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 trigger to stop the engine.
WARNING
Do not carry the machine with the engine running.
Stopping (Fig. 18)
Decrease engine speed, and push ignition switch (15) to stop position.
WARNING
Do not put the machine where there are fl ammable materials
such as dried grass, since the muffl er is still hot after the engine
has stopped.
NOTE
If the engine does not stop, it can be forced to stop by rotating the
choke lever to the choked position.
Before restarting the engine, ask HiKOKI Authorized Service
Centers for repairs.
WARNING
○ Do not overreach or cut above shoulder height.
○ Use extra caution when felling, and do not use the saw in a nose-
high position or above shoulder height.

CHAIN CATCHER

The chain catcher is located on the power head just below the chain
to further prevent the possibility of a broken chain striking the chain
saw user.
