The Dynapac LH 300 and LH 700 forward and reversible plate compactors are
heavy-duty plates for soil applications, ideally used for compaction of backfill in pipe
and cable trenches, as well as road repair and maintenance work.
They are fully hydraulic, which greatly improves the engine plate’s devibration. High
operational reliability is guaranteed because no moving parts are subjected to vibration.
The LH design includes a strong cover that withstands severe shock and also protects all vital
parts of the machine. The engine cover is foldable for easier access and service. The LH plates
are designed for operation in well ventilated spaces, as all combustion engine machines.

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 discovered 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 hazardous substances contaminate the
environment. Always dispose of used filters, drained oil and any remaining fuel
properly.
This manual contains instructions for periodic attention which should normally be carried out by
the operator.

SAFETY INSTRUCTIONS (FOR ALL LIGHT PRODUCTS)
Symbols
The signal words WARNING and CAUTION
used in the safety instructions have the
following meanings:
WARNING: Indicates danger or
hazardous procedure that could
lead to serious or mortal injury if
the warning is neglected.
CAUTION: Indicates danger or
hazardous procedure that could
lead to machine or property dam-
age if the warning is neglected.
Important rules for your safety
The machine must not be modified
withoutthepriorconsentoftheman-
ufacturer. Use only original parts.
Use only the accessories recom-
mendedbyDynapac.Ifmodifications
not approved by Dynapac are car-
ried out, these could result in seri-
ous injury to yourself or other per-
sonnel.
• 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 informa-
tion 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 ma-
chine 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
machine if you are tired or under the influence
of drugs, alcohol or other substances which
can effect your vision, reaction ability or judge-
ment.
Safety equipment
Longexposure toloud noisewithout
ear protectors can cause permanent
damage to hearing.
Longexposuretovibrationscandam-
age the hands, fingers and wrists.
Do not use the machine if you experi-
ence discomfort, cramp or pain. Con-
sult 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 ab-
sorbs 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 mate-
rial 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 exhaust pipe can get very hot
during operation, and can cause certain mate-
rial to ignite. Make sure that there are no other
personnel inside the working 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 unauthorized’s reach,
preferably in a locked container.

pointandcanbeexplosiveincertain
situations.Donotsmoke.Makesure
that worksite ventilation is good.
Keep away from all hot or spark-generating
objects when handling fuel. Wait until the ma-
chine has cooled before filling the tank. Fill the
tank at least 3 metres away from where you
intend to use the machine. Avoid spilling pet-
rol, diesel or oil on the ground. Protect your
hands from contact with petrol, diesel and oil.
Open the tank cap slowly to release any
overpressure that might exist in the tank. Do
not overfill the tank. Inspect the machine for

SAFETY INSTRUCTIONS (FOR ALL LIGHT PRODUCTS)
Working with the hydraulic system
Regular maintenance of the hydraulic system
is important. Minor damage or a split hose or
coupling can have devastating conse-
quences. 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 corro-
sive 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 minutes 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. Quali-
fied repair work requires trained personnel,
please contact your nearest authorized work-
shop.
Extinguishing fires
If there is a fire in or on the machine, it is
best to use an ABE-class fire extinguisher.
However, a BE-class CO2extinguisher is
also suitable.

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 machine.
Make sure that the work site is safe. Wet and loose
earth reduces manoeuvrability especially on sloping
ground. Always observe particular caution on slop-
ing 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
capability 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 sur-
face with the machine stationary. Vibration switched
OFF and all tanks full. Remember that loose ground,
vibration switched ON, and driving speed can all
cause the machine to topple even on a smaller
slope than specified here.
Never leave the machine unattended with
the engine running.
