The safety rules in this chapter only include
the general safety rules of machine. It’s
impossible to cover all the possible dangers.
If there is any problem, please report to your
superior before operation and maintenance.
1. SAFETY RULES
1.1 SAFETY MARKS
Figure on the right side is the mark to remind of safety, when you
see this mark on the machine or in the manual book; it indicates
that the human body is in danger of injury.
1.2 SAFETY LABELS
There are various labels at various points of machine, in
these labels, various words indicate various hurt risks, such
as “DANGER”, “WARNIGN”, “CAUTION” etc.
(as right figure), the meaning is as below:
1) DANGER—indicates an imminently hazardous
situation which, if not avoided, could result in
death or serious injury.
2) WARNING—indicates a potentially hazardous
situation which, if not avoided, could result in
death or serious injury.
3) CAUTION—indicates potentially
hazardous situation which, if not
avoided, may result in minor or
moderate injury.
“DANGER”, “WARNING” safety labels
are stuck at given points of machine
within the range of possible danger.
General attentions listed on the
“CAUTION” safety label. In this manual
book, “CAUTION” also reminds of safety
instruction.
1.3 GENERAL SAFETY INSTRUCTIONS
(1) Study the manual carefully and follow the safety
instructions in the labels and manual before
operating the machine.
(2) Always keep the safety labels clean. Change any
lost or damaged label with a new one. If the labels
or manual book are lost, you can contact dealer and
indicate the model of machine to purchase a new
one.
(3) Only qualified operator is permitted to operate this machine. Keep the machine in good

OPERATION & MAINTENANCE MANUAL SWE18UF
2
condition as per this manual.
(4) Don’t refit machine without authorization, otherwise it
will affect the performance and service life of machine, or
may cause human body hurt or even death.
1.4 PREPARATION FOR EMERGENCIES
All concerned people should be cautious so as to
prevent accident from occurring, and at the same time,
deposit first-aid kit and fire extinguisher nearby, and place
the phone numbers of hospital and fire department near
telephone to ask for help in case of emergency.
1.5 WEARING PROTECTIVE DEVICES
Before operation, always wear protective articles
when the work requires, they include:
Skintight work clothes
Hard hat
Safety gloves
Safety glasses, goggles, or mask
Respirator or filtration mask
Earplug or ear cap
1.6 CHECKING BEFORE START-UP
Before starting machine every day or every shift,
check the machine according to the contents in “Checking
before start-up” in this manual.
1.7 ADJUSTMENT OF OPERATOR’S SEAT
If you use this machine for the first time, or change
operator, the operator should adjust seat to make back
leaning against the seat and the feet operating the pedals at
ease. (Refer to 2.5 seat adjustment for details)
1.8 CORRECT ENTERING/LEAVING THE
MACHINE
Always face the machine when you use the steps and
hand-holds to enter or leave machine.
Never use any control lever as hand-hold.
Never enter or leave machine when the machine
travels, swings, or digs (lifts).
1.9 CORRECT START-UP OF ENGINE
The operator must sit on cab seat to start engine. Not allow
starting engine with the operator standing on crawler.
Not allow starting engine with short circuit start-up (including

OPERATION & MAINTENANCE MANUAL SWE18UF
3
terminal start-up).
1.10 FORBIDDING CARRYING PASSENGERS
When the machine is operating or traveling, prohibit other people except operator staying
on the machine.
1.11 KEEPING MACHINE AWAY FROM POWER TRANSMISSION LINE
Any part or load of machine touching electricity
transmission line will cause human death or GBH.
Prohibit machine or its load being close to electricity
transmission line, the machine should be 3 meters away
from line.
1.12 MOVING MACHINE SAFELY
Before the machine travels and swings, operator
should know the position of other people.
When machine travels or before it swings, operator
should warn other people by honking the horn.
Operation at confined area should use signal in
swinging, and harmonize the hand signal before
machine start-up.
Before operating the machine traveling, the operation
of traveling pedal/control lever should be
corresponding with the traveling direction.
Step on the foreside of traveling pedal or push
traveling lever forward, and the machine will travel
along tension wheel. By contraries, the machine will
travel along sprocket wheel.
When machine travel on a slope, place bucket as
figures, keep bucket 200-300mm above the slope
ground, if the machine slides or becomes unstable,
lower the bucket at once.
1.13 PREVENTING ACCIDENTS WHILE BACKING OR SWINGING
In order to prevent accident while backing or
swinging, the operator must follow:
Before back or swing the machine, look round and
confirm nobody is around.
Ensure that other people stand out of the boom swing
range.
Pay attention to that whether other people stay in
work range or not. Honk the horn or use other signals
to warn before moving the machine.

If the operator’s vision is blocked when the machine
backs, a signalman is needed and the signalman
should always be seen.
If signalman is needed, he or she should use hand
signals. Only when both signalman and operator
understand the meaning of signal, the operator can
operate the machine traveling and swinging.
Understand all the meanings of flag, mark, and signal,
and determine the person who is in charge of
signaling.
Keep the cleanness of window, mirror, and lamp.
When the visibility is weakened by dust, rain, and
fog, etc, lamp should be used.
Please read carefully and understand well the
operation contents of this manual book.
1.14 SAFE EXCAVATION WORK
Before excavation, operator should be aware of the
position of the embedded lines, such as cables, gas
pipes, water supply pipes, and operate the machine
carefully to prevent accidents.
All the non-working people should be away from the
working range of machine.
Make sure the ground of working site is hard enough
to support machine.
When the machine works at pithead, the tension
wheel end should be outward pithead, keeping the
traveling orientation vertical with pit cliff. In this
way, the machine can move away easily when the
cliff collapses.
When the machine works in deep spot, you should
prevent the boom bottom and cylinder from colliding
with high objects.
Turn over prevention
When the machine works on slope, the track should
be parked along the slope, retract the bucket as much
as possible, keep the bucket close to ground and
machine to avoid turning over.
When rotating with load, speed should be decreased
to avoid turning over. When working on frozen
ground, you should prevent the ascending
temperature from causing the ground to soften,
otherwise it will affect the stability of machine.
