2. GENERAL

2.1 INTRODUCTION

This maintenance manual describes all relevant

maintenance activities. It also contains safety

instructions, which must be strictly adhered to.

Activities not described in this manual, e.g.

replacing components, overhaul, fault-finding,

etc., are described in the DAF workshop

instructions.

This maintenance manual assumes that the

mechanic is sufficiently experienced and has had

the required instruction or training to carry out

these maintenance activities in a safe and

responsible manner.

The technical data and notes on the maintenance

activities have been compiled with the utmost

care.

2.2 TECHNICAL INFORMATION

The technical information in this maintenance

manual, such as notes on maintenance activities

and technical data required to carry out the

maintenance activities in a safe manner, were up-

to-date at the time this manual went to press.

DAF reserves the right to make changes without

prior notice.

Note:

Important changes relating to technical

information that is not contained in this manual

will be made available in TI sheets (Technical

Information Sheet).

2.3 WARNING SYMBOL

When text is accompanied by the warning symbol

shown here, the information provided is essential

for the health and safety of the mechanic.

This warning symbol is also shown if there are

circumstances in which there is a vehicle safety

hazard or damage to the vehicle could arise.

2.4 ENVIRONMENT

By carrying out the maintenance activities in a

professional manner, on time and at regular

intervals, you will help to reduce the impact on the

environment.

This means, for example, noticing and remedying

possible leakages in time and keeping the engine

in an optimum condition (adjusting valves,

replacing air filter element etc.), thus reducing the

emission of harmful exhaust gasses.

It should be noted that oils and fluids contain

harmful substances that have a negative impact

on the environment.

That is why you should take care that drained oils

and fluids and also discarded oil and fuel filters,

are collected in separate receptacles or

containers.

In short: maintenance activities must be

carried out in an environmentally aware

manner.

2.5 PARTS

All DAF parts and components have been

carefully attuned to each other, a decisive factor

in ensuring the original DAF quality.

It is only logical, therefore, that the original DAF

quality can be maintained best if original DAF

parts and components are used when replacing

parts or components.

As far as maintenance activities are concerned,

this includes components such as windscreen-

wiper blades, air-dryer elements, gaskets, V-belts

and filters.

For example, if "non-original DAF filters" are

used, the engine will be insufficiently protected

against fine microscopic airborne dust particles,

almost imperceptible metal swarf in the oil and

dirt in the fuel, resulting in:

-

premature replacing of cylinders, pistons,

bearings, valves, injector pump and other

moving parts

-

reduced engine performance

-

increased fuel consumption

Therefore, always use original DAF parts and

components.

2.6 MAINTENANCE GUIDELINES

-

When carrying out maintenance activities on

the vehicle, it is important that the work is

performed under the cleanest possible

conditions.

Filler caps, lubricating points, filler and drain

plugs should be cleaned before and after

maintenance activities.

-

When excessive leakage has been detected

at oil seals and/or components, or in case of

excessive drops in the oil level, a report

should be made and the cause should be

remedied.

-

It is important to check the gearbox

breathers, transfer box, rear axle and driven

front axle regularly for fouling and blockages.

If the breathers are blocked by dirt,

overpressure may cause leaks.

-

Depending on the circumstances in which

the vehicle is used, e.g. on very bad roads or

construction sites, important bolt

connections such as the fifth wheel, spring

suspension, U-bolts, trailer coupling,

steering box attachment, superstructure

attachments etc. should be inspected more

often and, if necessary, be retightened.

-

It is important that a visual inspection and

test run are carried out following the

maintenance activities.

Particular attention should be paid to

components directly related to driving safety.

-

Once a service has been completed new

information on the next service (mileage/

date) can be entered on the instrument panel

display using DAVIE XD via the VIC.
