Mack M359 - Front Suspension; Lifting, General; Rear Suspension

EMERGENCY ACTION
TOWING
Lifting, General
Vehicles must only be lifted by the lifting
points specied below. Always use
suitable lifting devices, such as clevises
and chassis guards, to avoid damaging
the vehicle.
Lifting Vehicle with Leaf
Springs
Front Suspension
Lift behind the front spring anchorage on
the chassis member, or beneath the
front axle.
Rear Suspension
Lift underneath the towing hitch cross
member. If the vehicle does not have a
towing hitch cross member, use the
chassis ends for lifting.
CAUTION
Remember to always use a chassis guard
when using a cross member for lifting.
1 Lifting Locations
Rear Suspension
If possible, avoid lifting the rear of a
truck with air springs. The consequence
could be that the air bellows slide apart,
unless you rst secure the rear axle to
the chassis.
NOTE
If the rear axle is xed to the chassis with
straps etc. when the vehicle is lowered,
the straps will burst when Automatic Ride
Height control is activated later on.
If you have to lift the rear of the vehicle
anyway, lift the towing hitch support
cross member in the rst instance. If the
vehicle does not have a towing hitch
support cross member, lift the chassis
ends.
If you lift the vehicle by the chassis, the
following applies:
1 The ignition lock must be in position
I or II and the air suspension in
"Automatic Ride Height" mode.
2 Lift the chassis until the wheels
almost leave the ground. Wait until
the air has drained out of the air
bellows.
3 If possible, secure the rear axle to
the chassis so that the air bellows
cannot slide apart.
4 Lift to the desired height.
