Case CX490D Operator's Manual page 162

Operating the machine on soft ground or in water
• The machine could gradually sink when working on soft
ground. Pay attention to undercarriage during work.
• Before operating the machine in water, check the water
depth and the footing. Permissible water depth is up to
the upper rollers.
• After operation underwater or on soft ground, apply
grease to the attachment and the turntable bearings.
Clean and inspect the undercarriage as well.
• In case of accidental sinking in water or soil up to the
swing body, replacement of grease and service are re-
quired. Terminate operation, and contact the CASE
CONSTRUCTION dealer.
NOTICE: Do not operate in a fast flowing stream.
Operating the machine on sloping ground
WARNING
Driving hazard!
Hillside operations can be dangerous. Rain, snow, ice, loose gravel, or soft ground, etc. can change
the ground conditions. You must make a judgment if it is safe to operate your machine on any hillside
or ramp.
Failure to comply could result in death or serious injury.
WARNING
Overturning hazard!
Before parking the machine, make sure the ground is stable. Plan the worksite so that the ground is
flat, hard, and level.
Failure to comply could result in death or serious injury.
The machine gradeability is 35° ( 70%).
NOTICE: Do not operate the engine when incline of the machine is 35° or more. The engine or the hydraulic system
may be damaged.
During hillside operations, be extra careful.
• Maintain the maximum engine speed.
• Make sure that the low speed travel is selected.
• Always keep the travel reduction gears pointing down towards the bottom of the slope.
• Always travel in the same direction as the slope, to prevent the machine from turning over. Never decelerate when
descending a slope.
• Raise the bucket about 40 cm (15.75 in) away from ground when ascending a slope. Contact the bucket on ground
to avoid slipping the machine when descending a slope.
• Avoid swinging to a direction of travel on a 15° slope, or avoid swinging perpendicular to direction of travel on a 10°
slope.
• During digging operation, avoid swinging the upperstructure towards the bottom of the slope with the bucket full.
