Hitachi CS 33EB Handling Instructions Manual page 9

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.
Chain brake operation (Fig. 10, 15)
Chain brake (15) 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 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 up the chain brake lever. (Fig. 10)
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. (Fig. 15)
In case the brake is not eff ective, ask our dealer 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 lever to stop the engine.
WARNING
Do not carry the machine with the engine running.
Stopping (Fig. 16)
Decrease engine speed, and push ignition switch (16) to stop
position.
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.
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 your servicing dealer,
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 saw when moving from one work place to another.
Always cut at wide open throttle. A slow moving chain can easily
catch and force the saw to jerk.
○ Never use the saw with only one hand.
You cannot control the saw properly and you may lose control
and injure yourself severely.
Keep the saw body close to your body to improve control and
reduce strain.
When cutting with the bottom part of the chain the reactive
force will pull the saw away from you towards the wood you are
cutting.
The saw will control the feeding speed and sawdust will be
directed towards you. (Fig. 17)
○ When cutting with the upper part of the chain the reactive force
will push the saw towards you and away from the wood you are
cutting. (Fig. 18)
