Chain Catcher - Hitachi CS 33EB Handling Instructions Manual

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. 12)
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. 12)
Chain brake operation (Fig. 3, 14)
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 (2) 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.
13)
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. 3, 14-18)
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. 14)
2. Set stop switch (17) to ON position. (Fig. 15)
3. Push priming pump (19) approximately ten times so that
fuel fl ows into carburetor. (Fig. 16)
4. Pull the choke lever (18) fully to set it in the START
position. (Fig. 16) 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. 17)
6. When you hear fi rst ignition, push the choke lever (18)
fully to set it in the RUN position. (Fig. 16)
NOTE
When the choke lever is put back to the RUN position
from the START position by hand after it is fully pulled,
the throttle lever will be kept half-open (half-throttle).
7. Pull recoil starter (20) rapidly again in the aforementioned
manner. (Fig. 17)
NOTE
If engine does not start, repeat procedures from 4 to 7.
8. As soon as the engine starts, pull throttle lever (22) full
once with the throttle lever lockout (21) pressed and
immediately release the throttle lever (22). Then half-
throttle is disengaged. (Fig. 18)
9. Pull the front hand guard (2) so that the brake is
disengaged. (Fig. 3)
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
avoid shortening the life 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 (Fig. 19)
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 lever to perform high-speed
operation for around 10 seconds. If chain oil is sprayed over
the stump, it is discharged properly.
WARNING
Do not carry the machine with the engine running.
Stopping (Fig. 20)
Decrease engine speed, and push stop switch (17) 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
setting the choke lever in the START position. Before
restarting the engine, ask Hitachi Authorized Service
Centers for repairs.
WARNING
○ Do not overreach or cut above shoulder height.
○ Use extra caution when felling, and do not use the chain
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.
WARNING
Do not stand in-line with chain when cutting.
BASIC TECHNIQUES FOR MAKING FELLING, LIMBING
AND BUCKING CUTS
The intention of the following information is to provide you
with the general introduction to wood cutting techniques.
WARNING
○ This information does not cover all specifi c situations,
which may depend on diff erences in terrain, vegetation,
kind of wood, form and size of trees, etc. Consult Hitachi
Authorized Service Centers, forestry agent or local
forestry schools for advice on specifi c woodcutting
problems in your area. This will make your work more
effi cient and safer.
○ Avoid cutting in adverse weather conditions, such as
dense fog, heavy rain, bitter cold, high winds, etc.
Adverse weather is often tiring to work in and creates
potentially dangerous conditions such as slippery
ground.
High winds may force the tree to fall in an unexpected
direction causing property damage or personal injury.
CAUTION
Never use a chain saw to pry or for any purpose for
which it is not intended.
WARNING
○ Avoid stumbling on obstacles such as stumps, roots,
rocks, branches and fallen trees. Watch out for holes
and ditches. Be extremely cautious when working on
slopes or uneven ground.
Shut off the engine when moving from one work place to
another.
Always cut at wide open throttle. A slow moving chain
can easily catch and force the chain saw to jerk.
