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. GENERAL

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.
