PART 3: GETTING TO YOUR ENGINE Raising the Cab
Raising the Cab
An independent hydraulic system raises and lowers the
cab. A positive, dual-locking device ensures safety and
eliminates danger of mishaps while driving.
WARNING! Do not get any part of your body un-
der an unsecured cab. It could cause a serious
or fatal accident. The cab could fall and crush
you. Always ensure the locking bar is fully en-
gaged before getting under the cab, or before
letting anyone else get under it (see following
instructions on using the locking bar).
WARNING!
• Raising the cab with heavy objects in the cab
can cause serious damage to the cab tilting
mechanism and cab. Before raising the cab,
remove heavy items such as tire chains and
tools. Remove or stow securely any loose
items. And shut the doors tightly.
• Straighten the front wheels before tilting the
cab or cab/tire damage could occur.
The following cab tilting instructions are labelled and in-
stalled on the base of the companion seat:
1. Park the vehicle on a level surface.
2. Apply the parking brake.
3. Make sure the shift lever is in Neutral. This will prevent
the shift lever from getting caught on the cab during
tilting operations.
4. Secure or remove all loose items in the cab. Close all
doors.
5. Check the clearance above and ahead of the cab. En-
sure there will be enough room to clear roof antennae
when you tilt the cab. Check for obstructions overhead
(branches, power lines, lights, etc.) and in front (walls,
work benches, other vehicles, etc.).
6. Place the control valve handle in the "Raise" position.
