2.8.9 Fasteners
When assembling/refitting components using
fasteners such as torque loaded bolts, nyloc nuts or
split pins etc., always use new fasteners. Do not re‑use
old fasteners except where specifically mentioned in
the text.
2.8.10 Protecting vehicle components during
grinding, drilling and welding
When grinding, drilling and welding or similar, take
appropriate precautions to prevent damage to pipes,
hoses, wiring, glazing, cab paintwork and rubber
suspension parts.
1. Shield vulnerable components from the sparks and
heat generated by grinding and welding.
2. If protection by shielding is not possible, remove
vulnerable components.
Caution:
If drilling holes, be aware of electrical
components behind the place where you
are drilling. Do not allow swarf to fall onto
electrical components, as this can result in
electrical short circuits.
Vehicles may be equipped with an automatic
chassis lubrication system, involving a number of
additional pipes. These pipes are made from plastic,
and are readily damaged. Refer to the chassis‑cab
manufacturer’s manuals for further information.
2.8.11 Welding on or near the vehicle
Exercise extreme care when carrying out welding
operations. Electric arc welding can cause serious
damage to any electronic items fitted to the vehicle.
1. Always stop the engine and disconnect the
batteries and electronic units in the approved
sequence (Refer to chassis‑cab manufacturer’s
workshop manual for information and instructions)
before carrying out any welding repairs.
2. Ensure that the vehicle is not leaking diesel, oil or
hydraulic fluids as these may ignite whilst welding.
3. Always have a serviceable fire extinguisher close at
hand.
4. Wear eye protection to protect eyes from welding
flash.
5. Erect protective screens to protect other personnel
from the dangers of the area.
2.8.6 Moving or rotating parts
There are risks of serious injury due to entanglement
or collision with rotating parts such as fans, engine
components or propeller shafts.
All personnel must be aware of the risks and take
precautions to distance themselves from moving or
rotating parts at all times.
All guards are to be fastened in position when the
vehicle is operational.
2.8.7 Hot components
Many vehicle components, i.e. the engine, gearbox,
brakes etc. operate at temperatures high enough to
cause skin burns to personnel coming into contact
with a recently operated engine unit.
Exhaust systems, turbochargers, catalytic converters
and their components can reach extremely high
temperatures.
To avoid the risk of skin burns, allow the vehicle
component to cool before carrying out any work.
Take care to avoid contact with hot components,
particularly exhaust system components, and fluids,
such as hydraulic system oil, on a vehicle when
carrying out tests with the engine running.
2.8.8 ‘Live’ work
It is sometimes necessary to perform adjustments to
the vehicle with the engine and vehicle systems ‘live’
(running).
1. Take great care when carrying out any ‘live’
(running) operations and adjustments.
2. Where possible, have an assistant standing by in a
position where they can stop the engine or vehicle
system in an emergency.
3. Locate and check the operation of all ‘Emergency
stop’ push‑buttons before starting any ‘live’ work.
