Lowering
1. Raise load high enough to clear the
jack stands.
2.
Carefully
remove jack stands (
always
used in pairs).
3.
Slowly
turn the handle counter-
clockwise, but no more than 1/2 turn.
If the load fails to lower:
a. Use another jack to raise the
vehicle high enough to reinstall
jack stands.
b. Remove the malfunctioning jack
and then the jack stands.
c. Using the other jack, lower the load
by turning the operating handle
counterclockwise, but no more
than 1/2 turn.
Note:
Close release valve by turning the
handle clockwise and open release valve
by turning the handle counterclockwise.
4. Push saddle down to reduce ram
exposure to rust and contamination
after removing jack from under the load.
MAINTENANCE
Important:
Use only a good grade
hydraulic jack oil. Avoid mixing different
types of fluid and
Never
use brake fluid,
turbine oil, transmission fluid, motor oil
or glycerin. Improper fluid can cause
failure of the jack and the potential for
sudden and immediate loss of load. We
recommend Mobil DTE 13M or
equivalent.
Adding oil
1. With saddle fully lowered set jack in its
upright, level position. Locate and
remove oil filler plug.
2. Fill with oil until ~3/16" above the inner
cylinder as seen from the oil filler hole.
Reinstall the oil filler plug.
Changing oil
For best performance, replace the
hydraulic fluid completely annually.
1. With saddle fully lowered,remove oil
filler plug.
2. Lay the jack on its side and drain the
fluid into a suitable container.
Note:
Dispose of hydraulic fluid in
accordance with local regulations.
3. Fill with oil until ~3/16" above the inner
cylinder as seen from the filler hole.
Reinstall the oil filler plug.
Lubrication
A periodic coating of light lubricating oil to
pivot points, axles and hinges will help to
prevent rust and assure that wheels,
casters and pump assemblies move
freely.
Cleaning
Periodically check the pump piston and
ram for signs of rust or corrosion. Clean
as needed and wipe with an oily cloth.
Note:
Never use sandpaper or abrasive
material on these surfaces!
Storage
Lower the saddle to its lowest position
when not in use.
OPERATION
Lifting
1. Place the vehicle in the park gear.
2. Engage emergency brake.
3. Securely chock wheels to prevent
inadvertent vehicle movement.
4. Turn handle clockwise firmly to close
release valve.
5. Center jack saddle under lift point.
6. Refer to the vehicle manufacturer's
owner's manual to locate approved
lifting points on the vehicle.
7. Verify lift point.
8. Pump handle to contact lift point.
9. Continue to pump handle until load
reaches desired height.
10.Transfer the load immediately to
appropriately rated jack stands.
(continued)
To avoid crushing and related injuries:
NEVER work on, under or around a
load supported only by a jack.
Immediately transfer the load to an
appropriate support device such as
jack stands
!
WARNING
Be sure all tools and personnel are
clear before lowering load. Dynamic
shock loads are created by quickly
opening and closing the release valve
as the load is being lowered. The
resulting overload may cause
hydraulic system failure.
