Lift Arm Brace
The lift arm brace (A) is intended to keep service per-
sonnel safe when it is necessary to work on a machine
with the lift arms in the raised position. It is not safe to
rely on the hydraulic system to hold the lift arms in the
raised position just as it is not safe to crawl under a
machine supported only by a jack. The lift arm brace is
used to support the weight of the lift arms much like
jack stands are used to mechanically support vehicle
weight.
To install the lift arm brace:
1.
Park the machine on level ground in a safe area
for performing service work.
2.
Remove any attachments that may be fastened to
the quick attach.
3.
Have an assistant remove the retaining pins (B)
securing the lift arm brace and remove it from the
machine.
4.
Make sure bystanders are clear of the lift arms,
then raise them to the upper limit.
5.
Have an assistant Install the brace around the
cylinder shaft as shown and reinstall the pins to
secure it to the cylinder.
6.
Lower the lift arms slowly until they come to rest
on the brace.
7.
It is now safe to shut the engine off and exit the
machine.
Do not work on or near the machine with the lift arms in
the raised position unless the lift arm brace has been
correctly installed.
To remove the lift arm brace:
1.
Start the machine and raise the lift arms until they
are clear of the brace.
2.
Once clear, have an assistant remove the brace
from the cylinder and stow it on the machine with
the pins.
3.
Once the brace has been stowed and the assistant
is clear of the lift arms, lower the arms to the
ground and shut the engine off to complete the
procedure.
