FUTURE REFERENCE
The LP 650/750 is a forward/reverse running, two-drum roller that is ideal for the compaction of earth
and asphalt compounds. The machine consists of a welded lower frame with a vibrator element located
between the two drums. Transmission to the vibrator element is made with the aid of hydraulic power
and propulsion is also hydraulic via chain drive to the drums. Infinitely regulated speed control
facilitates operation. The machine is equipped with a 56 litre (15 gallon) sprinkler system to permit long
shifts without the need of refilling. The water cock is well protected and easily accessible for the opera-
tor. The water tanks are made of plastic to avoid corrosion and the filler caps are large in order to
facilitate refilling. The lower part of the machine has a small overhang to allow the roller to be run
close to obstructions, eg, walls. The upper part is suspended by four rubber dampers and is secured to
the lower part with safety straps. The engine is fitted with a centrifugal clutch to relieve the hydraulic
system when idling. The machine is also equipped with a safety frame to protect the engine during
transport and work, and the frame is provided with a single-point hoisting bracket for easy loading and
unloading. The handlebar is retractable to facilitate transportation. The machine is equipped with a
dead-man’s handle. Electric starter, and push-stop to reduce the danger of crushing, are available as
optional accessories.
The machine and its accessories may only be used for their intended purpose. The LP rollers
are designed for operation in well ventilated spaces, as all combustion engine machines.

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 damage if the
warning is neglected.
Important rules for your safety
The machine must not be modified
without the prior consent of the manufacturer. Use only original parts.
Use only the accessories recommended by Dynapac. If modifications not
approved by Dynapac are carried out,
these could result in serious injury 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 machine 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 damage 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.
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 exhaust pipe can get very hot during operation, and
can cause certain material 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.

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 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
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. Qualified
repair work requires trained personnel, please
contact your nearest authorized workshop.
