1. SAFETY INSTRUCTIONS

1.1 SAFETY INSTRUCTIONS

General
The cab is equipped with a hydraulic tilting
mechanism. The pump is located on co-driver's
side at the rear of the cab. The cab locks are
opened hydraulically during pumping.

Before tilting the cab, make sure that the doors
are closed, that there are no loose items in the
cab and that the gear lever is in neutral. Tilt the
cab fully forward if work must be carried out
underneath the cab.

}

You can stop the cab tilting forward
at any time by turning the cock to the
reverse tilting position.

}

When working on a tilted cab (for
example when welding, spray-
painting or applying bitumen
coatings), be sure to cover the
piston rod of the lifting cylinder.
Welding spatter and paint on the
piston rod will inevitably cause
damage to the oil seal.

Inspection after a collision
Before tilting the cab after a collision, check the
cab rests, the cab hinges and the attachment of
the lifting cylinder to the chassis member and cab
for cracks.

}

If the vehicle has been involved in a
collision, the cab must under no
circumstances be tilted without due
precautions. The end stop in the
lifting cylinder may be damaged,
which might cause the cab to shoot
past its end stop.

If possible, suspend the cab in slings and put a
stand in front of the cab. Make sure that there is
no one in front of the cab while it is being tilted.

After a collision, always check the lifting cylinder
for internal damage. Replace the lifting cylinder if
damaged or if in doubt.

2.1 CAB SUSPENSION

The F230 cab is attached to the chassis at four
different points. Various cab suspension versions
are possible.

Day cab
Standard coil spring suspension with optional air
suspension at the front.

Sleeper cab
Standard coil spring suspension with optional air
suspension all round.

Spring suspension
The cab is attached to the chassis both at the
back and the front by coil spring.
elements. These elements are adjustable. There
is a stabiliser at the front.
At the back, the cab is damped laterally by two
horizontal dampers.
In the day cab model the horizontal dampers are
pointed outwards.
In the sleeper cab model the horizontal dampers
are pointed inwards.

Air suspension
The cab is attached to the chassis both at the
back and the front by air suspension
elements. The air suspension elements consist of
an air bellows with an internal shock absorber.
The system is equipped with height control
valves. The system has a stabiliser at the front.
At the back, the cab is damped laterally by two
horizontal dampers.

Suspension with coil spring and air
suspension elements (optional on day cab)
The cab is attached to the chassis at the front by
air suspension elements. The air suspension
elements consist of an air bellows with an internal
shock absorber.
The system is equipped with a height control
valve.
At the back, the cab is damped laterally by two
horizontal dampers.
The cab is attached to the chassis at the rear by
coil spring elements. These elements are
adjustable. The system has a stabiliser at the
front.

Tilting the cab with air suspension
When a cab with air suspension is lifted, the
height control valves register a rise in the cab
level which causes the air bellows to discharge.
Because of its weight the cab drops at the front
onto the stop in the spring element. This means
the cab can be tilted without problem and no extra
valves are necessary. No anti-dive valves are
fitted to the air suspension model.
