IF YOUR JACK BINDS
As your jack becomes older
,
the threads may start binding.
This
will prevent
the
jack
f
r
om operating
properly and safely. Rusty threads, dirty threads
,
or a worn
threads
can cause binding. Clean and
lubricate
the lifting mechanism.
Test the
jack by
j
ack
i
ng it
up without a load
.
If
the binding continues
,
refer
to
t
he
after
sa
l
e parts and serv
i
ce.
If
your jack binds while under a load
,
use a
jack
with equal or larger load capac
i
ty to
lower the load safely to the ground
.
Repeat the steps in
this
paragraph
to
the binding
jac
k.
Cleaning
If the moving parts of the equipment are obstructed, use cleaning solvent or another good degreaser to
clean the equipment. Remove any existing rust, with a penetrating lubricant.
Lubrication
If
the moving parts of the
jack
or if the steel screw is c
l
ogged, use air pressure
,
water pressure, or a stiff
brush
to
clean. Use a
non-flammable
cleaning solvent or another good de-greaser to clean the
jack.
Remove
a
n
y existing
rust
,
preferably
with
a penetrating lubricant.
Then
lubrica
t
e the
jack
using
white
l
i
th
i
um
grease,
light penetrat
i
ng
oil
,
or a silico
n
or
Teflon
spray at the
following
points
:
-Use a good lubricant on all moving parts.
-For light duty use, lubrication is needed once a month.
-For heavy and constant use, lubrication is recommended every week.
Do not use motor oil or grease to lubricate the jack
Rust Prevention:
-Check daily for any signs of rust or corrosion.
Without a load lift the equipment as high as it goes and look under and behind the lifting points. If signs of
rust are visible clean as needed.
WARNING:
Jack is not se
l
f-lubricating. It
w
i
ll not operate safely without proper
lub
r
ication
.
Storing the Jack
1.
Store in a dry location, recommended indoors.
2.
Mechanical jacks should be stored in an area where they will not be subjected to damage.
3.
If extreme temperatures or chemically active or abrasive environments are involved, the guidance
provided in shall be followed.
4.
Temperature - When mechanical jacks are to be used at temperatures above 140"F (60"C) or below
-20"F (-29"C), the jack manufacturer or a qualified person should be consulted.
5.
Chemically Active Environments -The strength and operation of mechanical jacks can be affected by
chemically active environments such as caustic or acid substances or fumes. The jack manufacturer or
a qualified person should be consulted before mechanical jacks are used in chemically active
environments.
6.
Other Environments - The internal workings of jacks can be affected by high moisture, gravel or sand,
silt, grit, or other dust-laden air. Jacks subject to these environments should have their inner
components frequently cleaned, inspected, and lubricated.
Note: If the jack is stored outdoors, be sure to lubricate all parts before and after use to ensure the jack
stays in good working condition.
