and rinse mouth.
1.11 Do not operate the machine, maintain or check the machine under the influence of alcohol
or medication.
1.12 The machine will stop when safety guard is opened. While the machine is running, opening
the guard will cause the power to shut off but the running parts do not stop immediately and
can still cause danger. Be sure to open the safety guard only when the machine has come
to a complete stop.
1.13 Do not stand on the front or rear supporting rollers to avoid accident by slipping.
1.14 Be sure to perform a machine check before starting and check periodically. After the job is
finished, clean both the machine and the working area thoroughly.

5.4 NOTICES FOR OPERATION
(1) The "EMERGENCY STOP" should be used at a proper time. Except for an emergent damage
to the machine or operator occurs, normally stopping the machine by pressing the SAW ARM
RAISE SWITCH is suggested. During cutting, when the "EMERGENCY STOP" button is
pressed, the power will be shut off immediately. At this time, the hydraulic system still has
remaining power to feed the blade but no power on the blade which may result in breaking of
the blade teeth.
(2) Use proper flow and density of cutting fluid. Too much flow and density are not helpful for
cutting and cause environmental pollution.
(3) The blade speed adjustment can be identified by the cutting sound. A smooth cutting sound
means correct blade speed. A "rushed" or "impact" cutting sound means incorrect blade
speed.
(4) When using a new blade, it is suggested to reduce the blade speed and sawbow downward
speed to perform blade friction about 3-5 cuttings. Then, set at normal speed to ensure the
blade life.
5.5 CUTTING INFORMATION
