dangers associated with the use and misuse of the product. If
any doubt exists as to the safe and proper use of this product
as outlined in this factory authorized manual, remove from
service immediately.
Inspect before each use. Do not use if leaking, broken, bent,
cracked or otherwise damaged parts are noted. If the cylinder
has been or suspected to have been subjected to a shock load
(a load dropped suddenly, unexpectedly upon it), discontinue
use until checked out by an BVA authorized service center.
Owners and operators of this equipment shall be aware that
the use and subsequent repair of this equipment may require

PRODUCT DESCRIPTION
The BVA Lock-Nut Cylinder Series is designed for rated
capacity load lifting and positioning. The Lock-Nut Series
comes with a threaded Ram Plunger containing a heavy
duty, knurled Lock-Nut. This Lock-Nut can be threaded up
and down the Ram Plunger threads to a provide a positive
means of securing load height without relying on hydraulic
pressure alone. A wide variety of applications exist for this
category of product. Special skill, knowledge and training
may be required for a specic task and the product may
not be suitable for all the jobs described above. Unsuitable
applications would include applications that call for a device
to move, level or support persons, animals, hazardous
materials, mobile homes/dwellings in general, mirrors and/or
plate glass, and/or to connect/secure hatches, components,
etc. between bulkheads. The user ultimately must make the
decision regarding suitability of the product for any given task
and therefore accept responsibility for that decision.
WARNING: Always check connections before using.
!
Alteration of these products is strictly prohibited. Use
only those adapters and attachments provided and
approved by the manufacturer.
WARNING: To reduce the risk of personal injury and/
!
or property damage, ensure that the rated working
pressure of each pressurized attachment be equal to or
greater than the rated working pressure developed by
the hydraulic pump.

INSTALLATION
NOTICE: Use an approved, high-grade pipe sealant to seal all
hydraulic connections.
1.
Remove the dust cover and rubber plug from coupler
2. Inspect all threads and ttings for signs of wear or damage, and
replace as needed. Clean all threads and ttings.
3. Connect hydraulic hose from hydraulic pump to the cylinder
coupler. Ensure that there are no uid leaks.
4. Install in-line pressure gauge.
5. Check for leaks in system and have repaired by qualified
personnel.
NOTICE: The use of cylinder attachments or extensions reduces
the cylinder capacity by at least 50% per attachment/extension.
!
WARNING: Before operating the pump, tighten all
hose connections with proper tools. Do not overtighten.
Connections should only be tightened securely and leak-free.
Overtightening can cause premature thread failure or high
pressure ttings to burst.
!
WARNING: Before repairs are made, depressurize cylinder.
Tips for hydraulic hoses & uid transmission lines:
• Avoid short runs of straight line tubing. Straight line runs do not
provide for expansion and contraction due to pressure and/or
temperature changes.
• Reduce stress in tube lines. Long tubing runs should be
supported by brackets or clips.
.
BEFORE USE

6. Ensure method of conrming load is accurate and working
properly. Have gauge or load cell accuracy veried by
qualied personnel on a yearly basis.
7. Cylinders should be stored where protected from the
elements, abrasive dust, and damage. These cylinders
should be stored in the vertical position.
