Lift Arm Support Device
The lift arm support device is used as a cylinder lock to prevent the raised lift arm
from lowering unexpectedly. Be sure to install the support device when the lift
arm is raised for service. When the support device is not being used, return it to
its storage position. The support device is a safety device, which must be kept in
proper operating condition at all times. The following steps ensure correct usage:
The safest method of engaging the lift arm sup-
port device requires two people - one person
inside the loader and another person outside the loader to engage
the support device.
Note: With the key switch OFF and the solenoid valve working properly, the lift
arm will stay raised when the lift control is moved to lower the lift arm. If the
valve does not hold the lift am and it begins to lower do not leave the operator’s
compartment. Instead, lower the lift arm and exit the machine. Then, contact
your Gehl dealer immediately to determine why the lift arm lowers while the key
switch is OFF.
Engagement
To engage the lift arm support device:
1. Lower the lift arm fully.
2. Stop the engine.
3. Have an assistant remove the lift arm
support device from its storage loca-
tion (Figure 4) on the left side of the
machine. Remove the lynch pin hold-
ing the support device up against the
lift arm. Allow the support device to
come down into contact with the lift
cylinder (Figure 4).
4. Restart the engine.
5. Use the lift control to raise the lift arm
until the support device drops over the end of the lift cylinder and around the
cylinder rod. Slowly lower the lift arm until the free-end of the support device
contacts the top end of the lift cylinder.
6. Look to be sure the support device is secure against the cylinder end. Then,
stop the loader engine, remove the key and exit the operator’s compartment.
Disengagement
The safest method of installing and removing
the lift arm support device requires two people
– one person inside the loader and another person outside the
loader to disengage the support device.
Important: With the key switch OFF and the solenoid valve working properly, the
lift arm will stay raised when the lift control is moved to lower the lift arm. If the
