SEE…
Rest the Bucket
When you park your excavator, lower the bucket
flat on the ground.
Resting the bucket takes the weight off the lift
cylinders.
Be sure the bucket’s drain holes aren’t clogged,
too. Plugged holes keep water from draining out.
Water that sits in the bucket causes rust.
Make sure you
install the loader’s
travel locks
before
driving the vehicle on
the road.
The locks hold the bucket in place about
a foot above the ground. That way the
bucket’s weight won’t ride on the hydraulic
cylinders—which can blow seals or
hydraulic lines. Also, close the front loader
shutoff valves. When the valves are closed,
the bucket won’t hit the ground or catch a
pothole—a real dangerous situation.
The locks also keep the bucket teeth
pointed up and out of the way of ground
obstacles.
Pages 2-86 through 2-88 of the TM 5-
2420-224-10 tell you how to open and
close the shutoff valves, and how to install
and remove the travel lock’s spring clips.
Clean out both drain holes
don’t forget
your bucket
pm… or
I’ll
suffer the
consequences!
Travel locks hold
bucket in place
with good
pm, I feel
better
already!
