OPERATION
Raise Saddle Assembly
1. Locate and close release valve by turning it clockwise
firmly, then pump the handle until the load is contacted.
2. Follow vehicle manufacturers recommended procedures
for removing the load as outlined in vehicle service manual
or repair guide.
3. Secure load with provided chains.
Important:
Ensure the transmission is centered on the
jack. An off-center transmission could cause the jack to
tip over resulting in property damage or personal injury. For
your safety, do not exceed 10
0
tilt angle of the saddle
assembly in all directions.
Lower Saddle Assembly
Caution:
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.
1
. Slowly, gently,
turn release valve counterclockwise to lower
load. No more than 1/2 full turn untill load is fully lowered.
2. Secure the transmission to the jack with the chain.
3. For model HW93718, adjust the bolt to the desired chain
link. The transmission should be tightly secured to the
jack if proper adjustment is used.
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.
Adding Oil
1. With saddle fully lowered, set jack in its upright, level
position. Locate and remove oil filler plug/ air vent screw.
2. Fill with oil until just below the rim of the oil filler hole,
then reinstall the oil filler plug/ air vent screw.

Symptom
REPLACEMENT PARTS
Not all components of the jack are replacement items,
but are illustrated as a convenient reference of location
and position in the assembly sequence. When ordering
parts, give Model number, parts number and description
on pages 5-8. Call or write for current pricing:
Phone:(888) 332-6419 or contact Hein-Werner Customer
Support, [email protected]
or 10939 N. Pomona Ave. Kansas City, MO 64153
Changing Oil
For best performance and longest lift, replace the
complete fluid supply annually.
1. With saddle fully lowered, and pump piston fully
depressed, remove oil filler plug/ air vent screw.
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. Set jack in its level, upright positon and fill with oil until
just below the rim of the oil filler hole.
4. Reinstall the oil filler plug / air vent screw.
Librication
1. A periodic coating of light lubricating oil to pivot points,
axles, and hinges will help to prevent rust and assure
that wheels, castors, and pump assemblies move freely.
2. When used on a daily basis, air pump model should be
internally lubricated before each use. Use
only
good
quality air tool lubricant.
Cleaning
Periodically inspect the 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
When not in use, store the jack with ram fully retracted.
