Dynapac LP8500 is a vibratory padfoot roller that is designed to cope with many different types of
compaction work. The roller is designed essentially for compaction tasks in pipe trenches, around
the foundations of buildings, backfilling against supporting walls, and also for road construction.
The machine is equally suitable for work in confined spaces as for major compaction jobs.
Like all other machines that are powered by combustion engines, the roller is designed for
operation in well-ventilated areas.

GENERAL
It is important that the machine is maintained correctly to
ensure proper function. It should be kept clean so that any
leakage, loose bolts and loose connections can be discov-
ered in time.
Make a habit of inspecting the machine every day before
starting up by checking all round it to detect any sign of
leakage or other faults.
SPARE A THOUGHT FOR THE ENVIRONMENT!
Do not let oil, fuel and other environmentally haz-
ardous substances contaminate the environment.
Always dispose of used filters, drained oil and any
remaining fuel properly.

Symbols
The signal words WARNING and CAUTION
used in the safety instructions have the follow-
ing meanings:
WARNING: Indicates danger or
hazardous procedure that could
lead to serious or mortal injury if
the warning is neglected.
CAUTION: Indicates danger or haz-
ardous procedure that could lead to
machine or property damage if the

Important rules for your safety
The machine must not be modified
without the prior consent of the man-
ufacturer. Use only original parts.
Use only the accessories recom-
mended by Dynapac. If modifications
not approved by Dynapac are carried
out, these could result in serious in-
jury to yourself or other personnel.
• These recommendations are based on
international safety standards.
• You must also observe any local safety
regulations which may be in force. Read all
instructions carefully before operating the
machine. Keep the instructions in a safe place.
• Signs and stickers giving important information
about safety and maintenance are supplied
with every machine. Make sure that they are
always legible. The ordering numbers for new
stickers can be found in the spare parts list.
• Use of the machine and its accessories is
restricted to the applications specified in the
product literature.
• For reasons of product safety, the machine
must not be modified in any way.
• Replace damaged parts immediately.
Replace all wear parts in good time.
Be alert
Always pay attention to what you are doing, and
use your common sense. Do not use the ma-
chine if you are tired or under the influence of
drugs, alcohol or other substances which can
effect your vision, reaction ability or judgement.
Safety equipment
Long exposure to loud noise without
ear protectors can cause permanent
damage to hearing.
Long exposure to vibrations can dam-
age the hands, fingers and wrists. Do
not use the machine if you experience
discomfort, cramp or pain. Consult a
doctor before resuming work with
the machine.
Always use approved safety equipment. The
operator, and people in the immediate vicinity of
the working area, must wear:
• Safety helmet
• Safety goggles
• Ear protectors
• Dust mask in dusty environments
• High-visibility clothing
• Protective gloves
• Protective shoes
Avoid wearing loosely fitting clothing that might
get caught in the machine. If you have long hair,
cover it with a hair net. Vibrations from hand-held
machines are transmitted into the hands via the
handles of the machine. Dynapac machines
feature a handle design that absorbs a large part
of the machine vibrations. The vibrations are not
eliminated entirely, but it is possible to use the
machines for longer periods of time without the
risk of injury.
Be alert to acoustic signals from other ma-
chines in the working area.
Working area
Do not use the machine near flammable material
or in explosive environments. Sparks can be
emitted from the exhaust pipe, and these can
ignite flammable material. When you take a pause
or have finished working with the machine, do not
park it on or near flammable materials. The ex-
haust pipe can get very hot during operation, and
can cause certain material to ignite. Make sure
that there are no other personnel inside the work-
ing area while the machine is in use. Keep the
worksite clean and free of extraneous objects.
Store the machine in a safe place, out of unauthor-
ized’s reach, preferably in a locked container.

SAFETY INSTRUCTIONS
Working with the hydraulic system
Regular maintenance of the hydraulic system is
important. Minor damage or a split hose or cou-
pling can have devastating consequences. Bear
in mind that the hydraulic hoses are made of
rubber and can deteriorate with age, which can
result in splitting. In all cases of uncertainty with
regard to durability or wear, replace the hoses
with new original hoses from Dynapac.
Working with battery
The battery contains poisonous and corrosive
sulphuric acid. Wear protective glasses and
avoid getting acid on your skin, clothes or on the
machines. If you get sulphuric acid on yourself,
rinse the skin with water. If you get acid in your
eyes, rinse them with water for at least 15 min-
utes and seek immediate medical treatment. The
gas that is emitted by the battery is explosive.
When fitting or replacing a battery, always take
care so that you do not short- circuit the battery
poles.
Repair
Never use a machine that is damaged. Qualified
repair work requires trained personnel, please
contact your nearest authorized workshop.
Extinguishing fires
If there is a fire in or on the machine, it is best
to use an ABE-class fire extinguisher. How-
ever, a BE-class CO2extinguisher is also
suitable.
Special safety instructions for Radio
Remote Controlled units
Even if you are accustomed to working with
radio control systems, read these operating
instructions carefully before using this
equipment. Only this document contains the
latest information relating to your Dynapac
radio control system.
For explanatory notes on obtaining an opera-
ting permit please refer to registration
documents enclosed in the appendix of this
operating instruction. Observe all applicable
work-safety and accident prevention
regulations carefully. Only fully trained,
authorized personnel may use the Dynapac
radio control equipment. Components, etc.
built in to the Dynapac equipment for safety
purposes must be regularly inspected.
If the Dynapac radio control unit develops a
fault, it must be shut down immediately. The
transmitter should be switched off with the start/
stop switch. The connecting cable must be
disconnected at the receiver from the connecting
socket (terminal) of the unit to be controlled. The
repair of the equipment must not be carried out
other than by Dynapac or an Dynapac authorized

Tipping angle on side slopes
When driving near an edge, at least two thirds of the
plate must be on firm solid ground.
If the machine tips over, switch off the
engine before attempting to lift the ma-
chine.
Make sure that the work site is safe. Wet and loose
earth reduces manoeuvrability especially on sloping
ground. Always observe particular caution on sloping
and uneven terrain.
Where possible, avoid all driving across a
slope. Instead, drive up and down on slop-
ing ground.
Never work on slopes that are greater than the capabil-
ity of the machine. Maximum slope of the machine in
operation is 20° (depending on condition of the ground).
The tilting angle is measured on a hard, level surface
with the machine stationary. Vibration switched OFF
and all tanks full. Remember that loose ground, vibra-
tion switched ON, and driving speed can all cause the
machine to topple even on a smaller slope than speci-
fied here.
Never leave the machine unattended with
the engine running.
