Save these instructions. For your safety, read and
understand the information contained within. The owner and
operator shall have an understanding of this product and safe
operating procedures before attempting to use this product.
Instructions and safety information shall be conveyed in
the operator’s native language before use of this product
is authorized. Make certain that the operator thoroughly
understands the inherent 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 a BVA Hydraulics
authorized service center. Owners and operators of this
equipment shall be aware that the use and subsequent
repair of this equipment may require special training and
knowledge. It is recommended that an annual inspection
be done by qualified personnel and that any missing or
damaged parts, decals, warning/safety labels or signs be
replaced with BVA Hydraulics authorized replacement parts
only. Any cylinder that appears to be damaged in any way, is
worn or operates abnormally shall be removed from service
immediately until such time as repairs can be made.

regarding suitability of the product for any given task and
therefore accept responsibility for that decision. Immediately
after lifting, loads must be supported by appropria te
mechanical means.

INSTALLATION
IMPORTANT! 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 fittings for signs of wear or damage,
and replace as needed. Clean all threads and fittings.
3. Connect hydraulic hose from hydraulic pump to the cylinder
coupler. Ensure that there are no fluid leaks.
4. Install in-line pressure gauge.
5. Check for leaks in system and have repaired by qualified
personnel.
Note: 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 leakfree. Overtightening can cause premature thread failure or
high pressure fittings to burst.
Before repairs are made, depressurize cylinder.
!
Tips for hydraulic hoses & fluid 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.

Cylinder must be on a stable base which is able
to support the load while pushing or lifting. Use
shims, friction material or constrains to prevent
slippage of the base or load. Ensure cylinder is fully engaged
