Engines Iveco N45, N67. Manual

Particular attention shall be drawn on some precautions that
must be followed absolutely in a standard working area and
whose non fulfillment will make any other measure useless
or not sufficient to ensure safety to the personnel in-charge
of maintenance.
Be informed and inform personnel as well of the laws in force
regulating safety, providing information documentation
available for consultation.
- Keep working areas as clean as possible, ensuring

adequate aeration.

- Ensure that working areas are provided with emergency

boxes, that must be clearly visible and always provided
with adequate sanitary equipment.

- Provide for adequate fire extinguishing means, properly

indicated and always having free access. Their efficiency
must be checked on regular basis and the personnel
must be trained on intervention methods and priorities.

- Organize and displace specific exit points to evacuate

the areas in case of emergency, providing for adequate
indications of the emergency exit lines.

- Smoking in working areas subject to fire danger must be

strictly prohibited.

- Provide Warnings throughout adequate boards signaling

danger, prohibitions and indications to ensure easy
comprehension of the instructions even in case of
emergency.

- Do not execute any intervention if not provided with

necessary instructions.

- Do not use any tool or equipment for any different

operation from the ones they’ve been designed and
provided for: serious injury may occur.

- In case of test or calibration operations requiring engine

running, ensure that the area is sufficiently aerated or
utilize specific vacuum equipment to eliminate exhaust
gas. Danger: poisoning and death.

SAFETY PRESCRIPTIONS
Standard safety prescriptions

Prevention of injury

- Do not wear unsuitable cloths for work, with fluttering

ends, nor jewels such as rings and chains when working
close to engines and equipment in motion.

- Wear safety gloves and goggles when performing the

following operations:
- filling inhibitors or anti-frost
- lubrication oil topping or replacement
- utilization of compressed air or liquids under pressure
(pressure allowed:

≤ 2 bar).

- Wear safety helmet when working close to hanging

loads or equipment working at head height level.

- Always wear safety shoes when and cloths adhering to

the body, better if provided with elastics at the ends.

- Use protection cream for hands.

- Change wet cloths as soon as possible

- In presence of current tension exceeding 48-60 V verify

efficiency of earth and mass electrical connections.
Ensure that hands and feet are dry and execute working
operations utilizing isolating foot-boards. Do not carry
out working operations if not trained for.

- Do not smoke nor light up flames close to batteries and

to any fuel material.

- Put the dirty rags with oil, diesel fuel or solvents in

anti-fire specially provided containers.

During maintenance

- Never open filler cap of cooling circuit when the engine

is hot. Operating pressure would provoke high
temperature with serious danger and risk of burn. Wait
unit the temperature decreases under 50

°C.

- Never top up an overheated engine with cooler and

utilize only appropriate liquids.

- Always operate when the engine is turned off: whether

particular

circumstances

require

maintenance

intervention on running engine, be aware of all risks
involved with such operation.

- Be equipped with adequate and safe containers for

drainage operation of engine liquids and exhaust oil.

- Keep the engine clean from oil tangles, diesel fuel and or

chemical solvents.

- Use of solvents or detergents during maintenance may

originate toxic vapors. Always keep working areas
aerated. Whenever necessary wear safety mask.

- Do not leave rags impregnated with flammable

substances close to the engine.

- Upon engine start after maintenance, undertake proper

preventing actions to stop air suction in case of runaway
speed rate.

- Do not utilize fast screw-tightening tools.

- Never disconnect batteries when the engine is running.

- Disconnect batteries before any intervention on the

electrical system.

- Disconnect batteries from system aboard to load them

with the battery loader.

- After every intervention, verify that battery clamp

polarity is correct and that the clamps are tight and safe
from accidental short circuit and oxidation.

- Do not disconnect and connect electrical connections

in presence of electrical feed.

- Before

proceeding

with

pipelines

disassembly

(pneumatic, hydraulic, fuel pipes) verify presence of liquid
or air under pressure. Take all necessary precautions
bleeding and draining residual pressure or closing dump
valves. Always wear adequate safety mask or goggles.
Non fulfillment of these prescriptions may cause serious
injury and poisoning.
