ELECTRICAL SYSTEM
WARNING
!
Disconnect the battery cables before performing any maintenance or
service.
Check the security of electrical terminals on the switches and relays i.e. nuts or screws loose,
which may cause local hot spot oxidation.
Inspect the components and wiring for signs of overheating i.e. discolouration, charring of
cables, deformation of parts, acrid smells and blistered paint.
BATTERY
Keep the battery terminals and cable clamps clean and lightly coated with petroleum jelly to
prevent corrosion.
The battery restraint should be kept tight enough to prevent the battery from moving.
PRESSURE SYSTEM
Regularly, it is necessary to inspect the external surfaces of the system (from the airend
through to the service valve(s)) including hoses, tubes, tube fittings and the separator tank, for
visible signs of impact damage, excessive corrosion, abrasion, tightness and chafing. Any
suspect parts should be replaced before the machine is put back into service.
TIRE PRESSURE
See the GENERAL DATA SECTION of this manual.
RUNNING GEAR/WHEELS
Check the wheel nut torque 20 miles (30 kilometres) after refitting the wheels. Refer to the
TORQUE SETTING TABLE later in this section.
Lifting jacks should only be used under the axle
The bolts securing the running gear to the chassis should be checked periodically for tightness
(refer to the MAINTENANCE CHART for frequency) and re-tighten where necessary. Refer to
the TORQUE SETTING TABLE later in this section.
