MAINTENANCE
Important: Use only good grade hydraulic jack oil. Avoid
mixing different types of uid and NEVER use brake uid,
turbine oil, transmission uid, motor oil or glycerin. Improper
uid can cause premature failure of the jack and the potential
for sudden and immediate loss of load. We recommend BVA
FJZ01 or equivalent.
Adding
1. With saddle fully lowered set jack in its upright, level
position. Locate and remove oil ller plug.
2. Fill with oil even with the bottom of the oil ller hole. Reinstall
the oil ller plug.
Changing oil
For best performance and longest life, replace the complete
uid supply at least once per year.
1. With saddle fully lowered set jack in its upright, level
position. Locate and remove oil ller plug.
2. Lay the jack on its side and drain the uid into a suitable
container.
Note: Dispose of hydraulic uid in accordance with local
regulations.
3. Fill with oil even with the bottom of the oil ller hole. Reinstall
the oil ller plug.
Lubrication
A periodic coating of light lubricating oil to pivot points will
help to ensure that pump piston linkages move freely.
Note: Never apply oil to saddle.
Cleaning
Periodically check the pump piston and ram plunger, and
saddle for signs of rust or corrosion. Clean as needed and
wipe with a clean, oil soaked rag.
Note: Never use sandpaper or abrasive material on these
surfaces !
Storage
Store the jack with pump piston, ram plunger/saddle
fully
lowered and release valve open, but never more than 1/2
turn. This will help prevent rust and corrosion to those critical
surfaces.

OPERATION
Use of this device may require special skills and
knowledge. Read, understand, and follow all printed materials
provided with and on this device before use.
Raising the Ram Plunger
1. Locate and close release valve by turning handle
clockwise until rm resistance is felt to further thread
engagement.
2. Pump until load reaches desired height. Immediately
secure with appropriately rated mechanical devices. It
is recommended you follow the load with cribbing and
blocking where practical.
Never allow personnel to work or pass under a load
until the load is secured by cribbing, blocking, or other
mechanical means.
Lowering
Make certain that all personnel are clear of the load
before lowering. Control the rate of descent of the load at
all times. The more you open the release valve, the faster
the load descends.
1. Use the manufacturer's provided operating handle
to engage and slowly turn the release valve counter-
clockwise, but no more than 1/2 turn.
If the operating handle is damaged, operates abnormally,
or will not positively engage the release valve, immediately
discontinue use of the jack until a manufacturer's replacement
handle assembly can be acquired.
2. Push ram down and handle sleeve in to reduce exposure
to rust and contamination after removing jack from under
load.
