3.11 LOWERING LIFT ARMS
(ENGINE OFF)
In the event that you should have an electrical failure which
renders your skid steer inoperable with the lift arms up, the
following procedures would apply.
WARNING
1. Lift Arm Height Is Sufficient To Engage
Lift Arm Support Pins
Engage lift arm support pins. (Fig. 3.10A) Raise seat bar
and cycle all controls to ensure they are locked. Exit loader
and open rear door. Locate the control valve on the RH
side of the machine. Unplug the electrical wire and remove
the knurled nut holding the solenoid on the spool lock.
Remove the solenoid, then remove the lock pin and spring
assembly (Fig. 3.10C). Once the lock pin and spring are
removed, the lift arm spool is free to travel. Enter the
machine, being careful not to cycle the foot pedals or the
control levers as the locking system has been disabled.
Once in the operator seat, dis-engage lift arm support pins.
Move the lift arm pedal or control lever to lower the lift
arms to the ground.
2. Lift Arm Height Is Not Sufficient To
Engage Lift Arm Support Pins
DO NOT EXIT FROM FRONT OF LOADER WITHOUT
LIFT-ARMS ON GROUND OR SUPPORTED BY
ACCEPTABLE MEANS!
Raise seat bar and cycle all controls to ensure they are
locked. If help is readily available, have someone place a
suitable support under the lift arms (e.g. 4" x 4" Lumber)
or a piece of angle iron between lift cylinder end cap and
lift cylinder rod mount.
Then exit loader using extreme caution. If help is not
available, the operator must exit the loader from the rear
window and perform the proper lift arm supporting (as
described previously). Once this is completed, open rear
door. Locate the control valve on the RH side of the
machine (Fig. 3.10B). Unplug the electrical wire and
remove the knurled nut holding the solenoid on the spool
lock. Remove the solenoid, then remove the lock pin and
spring assembly (Fig. 3.10C). Once the lock pin and spring
are removed, the lift arm spool is free to travel.
Ensure assistance is available, then the operator can enter
the machine, being careful not to cycle the foot pedals or
the control levers as the locking system has been disabled.
Once in the operator seat, have the assistant remove the lift
arm support devices. The operator can then move the lift
arm pedal or control lever to lower the lift arms to the
ground.
