If more than one person is working on the same vehicle, involuntary
movements could injure another person.
Example:
- By turning a wheel on a drive axle, parts of another drive wheel
may be caused to turn and injure somebody who is working with
e.g. the hub reduction gear.
- Working with the suspension equipment of axles (springs,
shock-absorber) may cause parts on the opposite side to start
moving.
- Manoeuvring from the driver is seat (tipper, trailing axle hoist,
loader) may cause parts to start moving, thereby causing
serious injury.
Protect others who work on the same vehicle
Be aware of the risks.
Warn those who work on the same vehicle or in its vicinity.
Do not start working with more than one drive wheel at the same
time until the half shaft has been removed.
More than one person working with the same object
Protective measures
Remove the negative (-) cable from the battery.
If power is needed from the electric system, connect a line fuse
(8A) between the battery terminal and the cable clamp.
This precaution also reduces the risk of burns and fires caused by
battery power.
Windscreen wipers
Even if the wipers have been turned off with the switch there is
voltage to the wiper motor (for the return stroke to parking posi-
tion). Only a slight turn of the motor is needed to start it.
Risk of injuring the fingers.
Protective measures
Do not loosen wiper motor before being sure that the power is
disconnected.
Other electric equipment
Disconnecting the batteries is a good safety precaution against
involuntary connections.
Protection against involuntary connection
of electric equipment
Be aware of the risks.
Disconnect the batteries when it is justified.
Involuntary start of electric motors etc.
