Steering Frame Lock - Separate and Connect
SMCS - 7506-029
Separation Procedure
Personal injury or death can result from machine articulation or
movement.
Machine frames can move and a person can be crushed.
Connect the steering frame lock link between the front and rear frames
before working on machine. Secure clevis pin with locking pin.
Before operating the machine, fasten the steering frame lock link into
the stored position and secure the clevis pin with locking pin.
Failure to lock into the stored position before operating can result in loss
of steering.

System Pressure - Release
SMCS - 4250-553-PX; 4300-553-PX; 4350-553-PX; 5050-553-PX
Release Procedure
Personal injury can result from hydraulic oil pressure and hot oil.
Hydraulic oil pressure can remain in the hydraulic system after the
engine has been stopped. Serious injury can be caused if this pressure is
not released before any service is done on the hydraulic system.
Make sure all of the attachments have been lowered, oil is cool before
removing any components or lines. Remove the oil filler cap only when
the engine is stopped, and the filler cap is cool enough to touch with
your bare hand.
Hydraulic System
Hydraulic oil pressure can remain in the hydraulic system on this
machine after the engine and pump have been stopped. Serious injury
can result if this pressure is not released before any service is done on
the hydraulic system. In order to prevent possible injury, release the
hydraulic system pressure before working on any fitting, hose, or
hydraulic component.
1/4(W)w

Lower all work tools to the ground before service is started. If the
hydraulic system must be serviced, tested, or adjusted with the work
tool in the raised position, the work tool and lift cylinders must be
supported properly.
Always move the machine to a location away from the travel of other
machines. Be sure that other personnel are not near the machine when
the engine is running and tests or adjustments are being made.
1. Park the machine on a hard, smooth, level surface. The location should also be dry and free
of debris.
2. Permit only one operator on the machine. All other personnel should be kept away from the
machine.
3. If the machine is equipped with a ride control system, place the ride control system into
“Service”.mode. Refer to “Ride Control” in this Operation and Maintenance, "Operator
Controls" section.
4. Position the bucket or the work tool just above the ground at a slight downward angle. This
position will ensure that the head end of the lift cylinders is pressurized.
5. Engage the parking brake.
6. Turn the engine start switch to the OFF position.
7. When the engine has stopped, turn the engine start switch back to the ON position so the
pilot oil can reach the main valve.
8. Move the implement lockout switch to the UNLOCKED position.
2/4(W)w

9. Move the lift control lever to the FLOAT position and the tilt control lever to the TILT
BACK position at the same time. This action allows the bucket or the work tool to tilt back
while the boom is lowered.
The bottom of the bucket or the work tool should rest flat on the ground. The weight of the
linkage should be supported by the ground. The pressure from the head end of the lift
cylinders and from the ride control accumulator is now vented to the hydraulic tank.
10. When the bucket or the work tool has settled to the ground, move both control levers to the
HOLD position. Cycle the control levers through all positions several times in order to
purge any remaining pressure from the implement hydraulic system. This action will
completely drain the pilot accumulator.
12. Slowly loosen the hydraulic tank filler cap in order to release the pressure from the
hydraulic tank.
13. After all of the pressure has been released, tighten the hydraulic tank filler cap. The
hydraulic system pressure has now been released. Hydraulic lines and components can now
be removed.
Release Procedure (Steering System, Braking System, and Quick Coupler) (If
Equipped)
Make sure all of the work tools have been lowered to the ground, and
the oil is cool before removing any components or lines. Remove the oil
filler cap only when the engine is stopped, and the filler cap is cool
enough to touch with your bare hand.
1. Park the machine on a hard, smooth, level surface. The location should also be dry and free
of debris.
2. Lower the bucket to the ground and stop the engine.
3. Engage the parking brake.
5. Turn the steering wheel fully to the left and fully to the right several times to relieve the
pressure in the steering system.
3/4(W)w

6. Depress the brake pedal repeatedly in order to release any pressure in the braking system.
When no more resistance is felt and no pressure release is heard, the braking system, and
Quick Coupler pressure is released.
7. Slowly loosen the hydraulic tank filler cap in order to release the pressure from the
hydraulic tank.
8. After all of the pressure has been released, tighten the hydraulic tank filler cap. The
hydraulic system pressure has now been released. Hydraulic lines and components can now
be removed.
