DESCRIPTION AND OPERATION
Standard Workshop Practices
Vehicle in Workshop
When working on a vehicle in the workshop always
make sure that:
- the parking brake is applied or the wheels are
securely chocked to prevent the vehicle moving
forwards or backwards.
- the key is removed from key operated hood
locks before any work is carried out around the
front of the vehicle.
- if the engine is to be run, there is adequate
ventilation, or an extraction hose to remove
exhaust fumes.
- there is adequate room to raise the vehicle and
remove the wheels, if necessary.
- fender covers are always fitted if any work is to
be carried out in the engine compartment.
- the battery is disconnected if working on the
engine, underneath the vehicle, or if the vehicle
is raised.
Alternative Fuel - Dons
- Do work on the vehicle in a designated area,
that is well ventilated and with access restricted
to qualified personnel only.
- Install new warning labels to their original
locations.
- If possible always isolate the alternative fuel
tank, and run the vehicle on the alternative fuel
until it automatically switches to its normal fuel
prior to taking the vehicle into the workshop
service area.
- Only use tested and approved components and
pipes when repairing or servicing
LPG and CNG
systems.
Alternative Fuel - Do Nots
- Do not vent off LPG fuel.
- Do not use shop air pressure to force LPG fuel
from the fuel tank.
( A CAUTION:When electric arc welding on a - Do not use paint drying ovens above 40°C for vehicle, always disconnect the generator any alternative fuel vehicle.

vehicles.
Alternative Fuel
A WARNING:When servicing the fuel system
always follow the recommended
procedures. Failure to follow these
instructions may result in personal injury.
If the odor of liquefied petroleum gas (LPG) or
compressed natural gas
(CNG) is present in the
air in the workshop, warn all persons in the area
to:
- extinguish all flames and lighted tobacco.
- shut off electrical and air powered equipment.
- evacuate the area.
- ventilate the area.
- contact the fire control authorities.
- remove the vehicle to a dedicated, ventilated
area.
- Do not evacuate fuel tanks unless there is repair
that requires the removal of the fuel tank.
- Do not work on the fuel lines or system
components unless the alternative fuel has been
evacuated and the pressure in the system
reduced to atmospheric or less.
- Do not use anything other than the specified
leak detector fluid to trace fuel leaks.
Be aware of situations that may cause the
LPG or I
CNG fuel system to vent off fuel, such as: I
- extremely hot days.
- parking by a space heater.
- hoisting a vehicle up near a ceiling heater.
Only fully trained personnel, who are conversant
with local standards, are to work on alternative fuel
vehicles.

DESCRIPTION AND OPERATION
Front Suspension
Overview
N0TE:During installation of the front wheel bearing
it is important to adhere to the specified installation
position, as the anti-lock brake system
( ABS )
sensor ring is located in the wheel bearing. A
coloured rubber ring is provided to indicate the
correct installation position. If the wheel bearing
were to be installed incorrectly then this would
cause failure of the ABS
.
A newly developed Mc-Pherson front suspension
with L-shaped lower arms is used. These lower
suspension arms are linked via large rubber
mountings to a reinforced and extremely rigid front
axle crossmember.
The ball head between the lower suspension arm
and the suspension strut is secured with three
rivets. Toe-in is adjusted via adjustable track rods.
The lower suspension arms can only be replaced as a complete unit.
