How to care for your engine
Warning! Read the "Safety precautions" and
remember them. They are given for your protection
and must be applied at all times.
This handbook is to assist you to maintain and operate
your engine correctly.
To obtain the best performance and the longest life
from your engine, you must ensure that the
maintenance operations are done at the intervals
indicated in "Preventive maintenance". If the engine
works in a very dusty environment or other adverse
conditions, certain maintenance intervals will have to
be reduced.
Renew the filter elements and lubricating oil regularly
in order to ensure that the inside of your engine
remains clean.
Ensure that all adjustments and repairs are done by
personnel who have had the correct training.
Lovol distributors have this type of personnel available.
You can also obtain parts and service from your Lovol
distributor.
The left and right sides of the engine are as seen from
the fly wheel.

Safety precautions
These safety precautions are important. You must refer also to the local regulations in the country of use. Some
items only apply to specific applications.
Only use these engines in the type of application for which they have been designed.
Do not change the specification of the engine.
Do not smoke when you put fuel in the tank.
Clean away fuel which has been spilt. Material which has been contaminated by fuel must be moved to a safe
place.
Do not put fuel in the tank while the engine funs (unless it is absolutely necessary).
Do not clean, add lubricating oil, or adjust the engine white it runs (unless you have had the correct training;
even then extreme caution must be used to prevent injury).
Do not make adjustments that you do not understand.
Ensure that the engine does not run in a location where it can cause a concentration of toxic emissions.
Other persons must be kept at a safe distance while the engine or equipment is in operation.
Do not permit loose clothing or long hair near moving parts.
Keep away from moving parts during engine operation. Attention: Some parts cannot be seen clearly while
the engine runs.
Do not operate the engine if a safety guard has been removed.
Do not remove the filler cap of the cooling system while the engine is hot and while the coolant is under
pressure, because dangerous hot coolant can be discharged.
Do not allow sparks or fire near the batteries (especially when the batteries are on charge) because the gases
from the electrolyte are highly flammable. The battery fluid is dangerous to the skin and especially to the
eyes.
Disconnect the battery terminals before a repair is made to the electrical system.
Only one person must control the engine.
Ensure that the engine is operated only from the control panel or from the operator's position.
If your skin comes into contact with high-pressure fuel, obtain medical assistance immediately.
Diesel fuel and lubricating oil (especially used lubricating oil) can damage the skin of certain persons.
Protect your hands with gloves or a special solution to protect the skin.
Do not wear clothing which is contaminated by lubricating oil. Do not put material which is contaminated
with oil into the pockets.
Discard used lubricating oil in a safe place to prevent contamination.
Ensure that the control lever of the transmission drive is in the "out-of-drive" position before the engine is
started.
Attention shall be especially paid when maintenance carried out under bad conditions.
The combustible material of some components of the engine (for example certain seals) can become
extremely dangerous if it is burned. Never allow this burnt material to come into contact with the skin or with
the eyes.
When checking pressure of the parts in water box, safety barrier shall be used to protect the operators. Secure
the seal plug of the part to be checked with safety iron wire.
Don’t contact compressed air with your skin. If your skin comes into contact with compressed air, obtain
medical assistance immediately,
Turbocharger works at high-speed and high temperature. Keep the fingers, tools or other chips away from the
inlet and outlet of the Turbocharger and avoid contacts with the hot surface.
Fit only genuine Lovol parts.

Engine identification
Phaser series for vehicle use consists of a range of
both four and six cylinder engines. Each type of
cylinder will have four basic engine types, naturally
aspirated, compensated, turbocharged and
turbocharged/intercooled.
There are different model variations within each
cylinder type.
Identification of the various models is by a system of
similar power output, for example:
Phaser 110T – a 4-cylinder engine with a rate output
power of 106 horsepower.
“T” indicates Turbocharged.
Pharser 210Ti --- 6 cylinder engine with a rated output
power of 210 horsepower.
“Ti” indicates turbocharged and intercooled engine.

How to start the engine
Several factors affect engine start, for example:
The power of the batteries.
The performance of the starter motor.
The viscosity of the lubricating oil.
The installation of a cold start system.
Diesel engines need a cold starting aid if they are to start in
very cold conditions;
Diesel engines need a starting aid if they are to start in very
cold conditions. Normally, your vehicle or your machine will
be fitted with the correct equipment for your region of
operation.
For the Phaser/1000 Series engines, these systems are:
Fuelled starting aid:
An electrically operated device which ignites a specific
amount of diesel fuel in the induction manifold in order to
heat the induction air.
Attention: If the engine has not run for several weeks, see
"Attention" on page 7.02.
3.02

How to start a warm engine
1. If the engine is equipped with a manual stop control, ensure that
it is in the "run" position.
2. Adjust the engine speed control to the quarter open position.
3. Turn the start key to the "HS" or "S" position to engage the
starter motor;
4. Allow the start key to return to the "Ft" position, as soon as the
engine starts. Always ensure that the engine and starter motor
are stationary before the starter motor is engaged again.
How to start a cold engine
1. If the engine is equipped with a manual stop control, ensure that
it is in the "run" position.
2. Adjust the engine speed control to the maximum speed position.
3. Turn the start key to the "S" position to engage the starter motor.
Allow the key to return to the "R" positron, when the engine
starts. Then adjust the engine speed control to get an even idle
speed.
4. If the engine does not start in 30 seconds, allow the start key to
return to the "R" position for another 30 seconds. Then engage
the starter motor again for a maximum period of 30 seconds.
Attention: Ether type fuels must not be used at the same time as
a fuelled starting aid.
3.03

How to start a cold engine with the fuelled starting aid
1. If the engine is equipped with a manual stop control, ensure that it is in the "run" position.
2. Turn the start key to the “H” position (A) and keep it there for 15 seconds.
3. Adjust the engine speed control to the maximum speed position.
4. Turn the start key to the "HS" to engage the starter motor. Allow the Start key to return to the "R" position when
the engine starts. Then adjust the engine speed control to give an even idle speed;
5. If the engine does not start in 15 seconds, turn the start key to the "H" position and hold it there for 10 seconds.
Then engage the starter motor again.
How to stop the engine
Attention: It is recommended that a turbocharged engine is run at approximately 1000 rev/min at a reduced load for
2-3 minutes before it is shut down. This will allow the turbocharger to cool.
Adjust the engine speed control to the minimum speed position.
According to the equipment fitted, either turn the engine start key to the "O" position (3.03/A) or operate the manual
stop control. If a manual stop control is used,
Ensure that the control returns to the "run" position after the engine has stopped. Also ensure that the engine start key
is turned to the "O" position.
Adjustment of engine speed range
The idle or maximum speed settings must not be changed by the engine operator because this can damage the engine
or transmission. The warranty of the engine can be affected if the seals on the fuel injection pump are broken during
the warranty period by a person who is not approved by Lovol.
Running-in
Attention:
Do not operate the engine at high speeds without a load.
Do not overload the engine.
A gradual running-in of a new engine or POWER EXCHANGE engine is not necessary. Prolonged operation at light
load during the early life of the engine can cause lubricating oil to enter the exhaust system. Maximum load can be
applied to a new engine as soon as the engine is put into service and the coolant temperature has reached a minimum
of 60℃（140℉）.
The engine will benefit if the load is applied as soon as possible after the engine is put into service.
Turbocharged engines
Because of the power characteristics of the turbocharged engine it is necessary to maintain a high engine speed when
you climb a gradient. To ensure that the engine is not overloaded at low engine speeds engage a lower gear.
Altitude
If the naturally aspirated engine is to run at an altitude above 600 m (2,000 ft), the fuel delivery can be changed to
reduce fuel consumption and smoke. Lovol can give the percentage of fuel reduction necessary if details of engine
application and ambient conditions are given.
