NOTICE
Make sure the grille is open before tilting the cab
(vehicles built from June 2011). Leaving the grille
closed while tilting the vehicle will cause damage
to the grille.
IMPORTANT: Vehicles built February 2012 and
later are equipped with a safety mechanism that
prevents the tilt pump from operating when the
grille is not open.
4. Fully open the grille.
5.
Check the cab travel path for obstructions.
6. Move the pump control lever to the TILT position.
See
Fig. 2.13 .
7. Press and hold the button on the pump to disen-
gage the hold-down latches and begin tilting the
cab.
IMPORTANT: Check the indicator pin on each
cab latch. The latches have disengaged if the
pins are out. See
Fig. 2.11 .
DANGER
Make sure the safety stop is engaged on the right
tilt cylinder rod. If the safety stop isn’t engaged,
and the cab should drop, the result could be seri-
ous injury or death.
8. When the cab reaches a 30-degree angle, stop
tilting the cab by letting go of the pump button.
Engage the safety stop on the right tilt cylinder
rod. See
Fig. 2.14 . The safety stop prevents the
cab from accidentally dropping below this
position.
9. To tilt the cab all the way, press and hold the
button on the pump until the cab nears a 45-
degree angle (the balance point). See
Fig. 2.15 .
Once the cab goes beyond 45 degrees, release
the button on the pump and move the tilt pump
lever to the RETURN position in order to slow
cab descent.
IMPORTANT: If the cab stops after it has gone
beyond 45 degrees, don’t force it down with the
tilt pump. The velocity fuses have locked the tilt
cylinders. To unlock them, see
Hydraulic
Lockup , below.
Returning the Cab to Operating
Position
DANGER
Stay completely clear of the cab’s travel path at
all times. Once the safety stop has been re-
leased, don’t lean over the frame rails, the en-
gine, or the transmission for any reason. To do
so could result in serious injury or death.
1. Move the pump lever to the RETURN position.
