OPERATION
Raise saddle
For Models KTI-63503, KTI-63504 & KTI-63505:
Caution! For Model KTI-63504, do not operate the jack
by pumping the lift pedal and pressing the air pump pedal
at the same time.
a. Pump foot pedal or press air pump pedal until saddle
reaches desired position.
b. Follow vehicle manufacturers recommended procedures
for removing the load as outlined in vehicle service
manual or repair guide.
c. Secure load with provided restraints. Ensure load's center
of gravity is centered on the saddle and load is stable
before moving jack.
For Model KTI-63511:
Locate and close release valve by turning knob clockwise
firmly, then pump the pump handle until the load is
contacted.
Lower saddle
Caution! Be sure all tools and personnel are clear before
lowering load.
For Models KTI-63503, KTI-63504 & KTI-63505:
Slowly, gently apply downward pressure to the release valve
pedal.
For Model KTI-63511:
Slowly, gently turn the release valve knob
counterclockwise, NEVER MORE THAN 1/2 FULL TURN
until the load is completely lowered.
Note: 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.
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. Im-
proper fluid can cause failure of the jack and the potential
for sudden and immediate loss of load. Fill with good quality
jack oil. We recommend Mobil DTE 13M or equivalent.
Adding oil
For Models KTI-63503, KTI-63504 & KTI-63505:
1. With saddle fully lowered, and jack in its upright, level
position. Remove oil filler screw.
2. Fill with oil until just below the rim of the oil filler screw
hole. Reinstall the oil filler screw.
For Model KTI-63511:
1. With saddle fully lowered, remove oil filler plug.
2. Fill to ~3/16" above the inner cylinder as seen from the
oil filler plug hole. Reinstall oil filler plug.
MAINTENANCE (continued)
Changing oil
For best performance and longest life, replace the
complete fluid supply at least once per year.
Note: Dispose of hydraulic fluid in accordance with
local regulations.
For Models KTI-63503, KTI-63504 & KTI-63505:
1. With saddle fully lowered, remove the oil filler screw.
2. Lay the jack on its side and drain the fluid into a
suitable container.
3. Fill with oil until just below the rim of the oil filler screw
hole. Reinstall the oil filler screw.
For Model KTI-63511:
1. With saddle fully lowered, remove oil filler plug.
2. Lay the jack on its side and drain the fluid into a
suitable container.
3. Fill to ~3/16" above the inner cylinder as seen from
the oil filler plug hole. Reinstall oil filler plug.
Lubrication
1. 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.
2. When used on a daily basis, air pump models should
be internally lubricated before each use. Use only
good quality air tool lubricant. If no inline oiler is used,
pour a teaspoon of air tool oil into the inlet of the air
control valve. Simply operate the jack using the air
feature in order to fully distribute the oil.
Cleaning
Periodically check 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
and air supply disconnected.
