Description
This Westward Hydraulic 2.5 Ton Spider Jack is designed for lifting, but not sustaining a lift. The Spider Jack (1MZK7) rotates 360° for
maximum maneuverability and easy placement. It is to be used in conjunction with jack stands. Intended use: To lift one axle of a vehi-
cle for the purpose of service and /or repair of vehicle components. After lifting, loads must be immediately supported by appropriately
rated jack stands. Check with vehicle manufacturer’s owners manual for proper lift points. This jack complies with applicable ASME /
ANSI Standards.

General Safety Information
Study, understand,
and follow all instructions before oper-
ating this lifting device. Intended use is
for lifting part of a total vehicle, only
one wheel or axle at a time.
Immediately after lifting, support the
vehicle with appropriate means. Do not
get under or allow anyone under vehi-
cle until supported by jack stands. Do
not exceed rated capacity. Use only on
hard, level surfaces capable of sustain-
ing rated capacity loads. Lift only on
those areas of the vehicle as specified
by the vehicle manufacturer.
Do not move or dolly the vehicle while
on the jack. Keep children away from
jack. Ensure that the lift point is proper-
ly centered on the jack saddle. Always
wear safety glasses when using this
equipment. Inspect jack before each
use. Do not use if bent, broken, leaking,
or damaged components are observed.
No alteration of this product is allowed.
Do not use this device for any purpose
other than that for which it was intend-
ed. Failure to heed any one or combina-
tion of these warnings may result in
severe personal injury and/or property
damage.
Assembly
1. Always secure the handle by pushing
the handle into the socket and turning
until the handle locks into place. Tighten
securely to prevent accidental removal
of handle while in use.
2. Before use, a visual inspection of the
jack should be made looking for bent,
worn or loose parts, or hydraulic leaks.
If any of these conditions exist, the jack
should be removed from service.

Operation
Operation
Off-centered loads
and loads lifted while jack is not level
may damage the jack or cause personal
injury.
RAISING VEHICLE
1. Make sure the jack and vehicle are on a
hard level surface.
2. Always set the vehicle parking brake
and block the wheels.
3. Consult the vehicle owners manual to
ascertain the location of lift points and
position the jack under the prescribed
lift point.
4. Turn the release valve clockwise to the
closed position. Do not over tighten!
5. To raise the vehicle to desired height,
place the handle into the socket and
pump up and down.
6. Place jack stands beneath the vehicle
at locations recommended by the vehi-
cle manufacturer. Do not get under the
vehicle without jack stands. Jacks are
not designed to maintain heavy loads
for long periods of time.
7. Turn release valve slowly counterclock-
wise to lower load onto jack stands.
This is a lifting
device only. The load must be support-
ed immediately by other appropriate
means. Keep hands, feet, and clutter
clear of ground area when lowering
the load.
LOWERING VEHICLE
1. Turn the release valve clockwise to the
closed position.
2. Pump the handle to lift vehicle off of
jack stands
3. Remove the jack stands. Do not get
under or let anyone else under the vehi-
cle while lowering.
4. Turn the release valve SLOWLY coun-
terclockwise to lower the vehicle onto
the ground.
Avoid shock loads
created by quickly opening and closing
the release valve as the load is being
lowered. Shock loads can create dan-
gerously high operating pressures
within the hydraulic system, causing
system failure and resulting in personal
injury and/or property damage.
Inspection
The product shall be maintained in accor-
dance with the product instructions. No
alterations shall be made to this product.
1. The product shall be inspected immedi-
ately if the jack is believed to have been
subjected to an abnormal load or shock.
It is recommended that this inspection
be made by an authorized customer
service representative prior to use.
2. Repair of this equipment requires spe-
cialized knowledge and facilities. If the
jack is subjected to abnormal load or
shock, remove from service and have it
examined by an authorized inspection
facility for parts or repairs. An annual
inspection of the product should be
made by a manufacturer’s authorized
repair facility. Any defective parts,
decals, or safety labels shall be
replaced with manufacturer’s specified
parts.
Maintenance
Monthly maintenance is recommended.
Lubrication is critical to jacks as they sup-
port heavy loads. Any restriction due to
dirt, rust, etc., can cause either slow
movement or extremely rapid jerks, dam-
aging the internal components. The follow-
ing steps are those designed to keep the
jack well lubricated:
1. Lubricate the ram, linkages, saddle and
pump mechanism with light oil. Grease
wheel bearings and axles.
2. Visually inspect for cracked welds, bent,
loose, missing parts or hydraulic oil
leaks.
3. If jack is subjected to abnormal load or
shock, remove from service and have it
examined by an Authorized Repair
Service.
4. Clean all surfaces and maintain all
labels and warnings.
5. Check and maintain the ram oil level.
IMPORTANT: Do not use brake or trans-
mission fluids, or regular motor oil as
they can damage the seals. Always pur-
chase and use products labeled
Hydraulic Jack Oil.
CHECKING OIL
1. Turn handle counterclockwise to allow
ram to fully retract. It may be necessary
to apply force to the saddle for lowering.
2. With jack in upright position remove oil fill
plug. Oil should be even with bottom of
hole. If not, top up. Do not overfill. Always
fill with new, clean hydraulic jack oil.
3. Replace fill plug.
4. Check jack operation.
CHANGING OIL
For best performance and longest life,
replace the complete fluid supply at least
once per year.
1. With saddle fully lowered and pump pis-
ton fully depressed, remove the fill plug.
2. Lay the jack on its side and drain the
fluid into a suitable container.
NOTE: Dispose of hydraulic fluid in accor-
dance with local regulations.
3. Fill with good quality hydraulic oil, rein-
stall the fill plug.
LUBRICATION
1. Applying a 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.
2. 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 !
SYSTEM AIR PURGE
1. Turn release valve counterclockwise one
full turn to open.
2. Pump handle eight full strokes.
3. Turn release valve clockwise to close
valve.
4. Pump handle until the lift arm reaches
maximum height and continue to pump
several times to remove trapped air in
the ram.
5. Carefully and slowly pinch oil fill plug to
release trapped air.
6. Turn release valve counterclockwise one
full turn and lower lift arm to the lowest
position. Use force if necessary.
7. Turn release valve clockwise to closed
position and check for proper pump
action. It may be necessary to perform
the above more than once to assure air
is evacuated totally.
Storage
Always store your jack in the fully lowered
position. This will protect critical areas
from excessive corrosion.
Alterations
Because of the potential hazards associat-
ed with the misuse of this type of equip-
ment, no alterations shall be made to the
product without written authorization of the
manufacturer or supplier.
