Before Use - BVA Hydraulics HL1001D Mode D'emploi

INSTALLATION
IMPORTANT! Use an approved, high-grade pipe
all hydraulic connections.
1. Remove the dust cover and rubber plug from coupler.
2.
and replace as needed.
4. Connect hydraulic hose from hydraulic pump to the cylinder
5. Install in-line pressure gauge.
6.
Note: The use of cylinder attachments or extensions reduces
the cylinder capacity by at least 50% per attachment/extension.
!
Before operating the pump, tighten all hose connections with
proper tools. Do not over tighten. Connections should only
be tightened securely and leak-free. Overtightening can cause
!
Before repairs are made, depressurize cylinder.
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

1. Before using this product, read the owner's manual completely
and familiarize yourself thoroughly with the product, its components
and recognize the hazards associated with its use.
2. Verify that the product and the application are compatible. Inspect
before each use. Do not use if bent, broken, leaking or damaged
components are noted.
3. Carefully remove the dust caps and plugs from hose coupler and
ram coupler.
4. Connect hose coupler to ram coupler, ensure that there are no
fluid leaks.
5. Check for leaks in system and have repaired by qualified personnel
as needed. Before repairs are made, depressurize cylinder.
6. Replace worn or damaged parts and assemblies with BVA
Hydraulics Authorized Replacement Parts only (See Replacement
Parts Section). Lubricate as instructed in Maintenance Section.
7. Use adequate eye protection when operating or near this equipment.
8. Ensure method of confirming load is accurate and working
properly. Have gauge or load cell accuracy verified by qualified
personnel on a yearly basis.
9. Cylinders should be stored where protected from the elements,
abrasive dust, and damage. These cylinders should be stored
in the vertical position.
OPERATION
Operate the hydraulic pump to advance and retract the cylinder.
Do not continue pumping when cylinder is fully extended. Internal
pressure will build up and may damage the seal of the cylinder.
!
To help prevent material fatigue if the cylinder is to be used
in a continuous application, the load should not exceed
85% of the rated capacity.
!
Your cylinder, hose(s), couplings and pump all must be
rated for the same maximum operating pressure, correctly
improperly matched system can cause the system to fail.
!
1. Inspect hoses and connections daily. Replace damaged
sealant to seal
components immediately with BVA Hydraulics Replacement
Parts only.
2. Tighten connections as needed. Use pipe thread sealing
compound when servicing connections.
3.
(never exceed 400 hours). Follow pump manufacturers
Oil (HV15) or equivalent when using with hand pump or air
pump, BVA Hydraulics Oil (HV68) or equivalent when using
turbine oil, motor oil, alcohol, glycerin etc. Use of other than
good quality hydraulic oil will void warranty and damage the
cylinder, pump, hose etc.
4. Use an approved, high-grade pipe thread sealant to seal all
layer of tape is used and it is applied carefully (two threads
back) to prevent the tape from being introduced into hydraulic
system. A piece of tape could travel through the system and
obstruct the flow of fluid and adversely affect function.
Lubrication & Cleaning
Keep cylinder clean at all times.
1. Any exposed threads (male or female) must be cleaned
and lubricated regularly, and protected from damage.
Lubricate with light machine oil.
2. If a cylinder or ram has been exposed to rain, snow, sand,
airborne abrasive, or any corrosive environment, it must be
cleaned, lubricated, and protected immediately after exposure.
Daily clean exposed ram with clean cloth dampened with
light machine oil. Protect exposed ram from the elements
at all times.
3. Keep the hydraulic system as free of dirt as possible. When
not in use, couplers must be sealed with dust covers. All
hose connections must be free of dirt and grime. Any
equipment attached to the cylinder must be kept clean.
Storage
Cylinders should be stored vertically with ram plunger fully
retracted in a dry, protected area, not exposed to corrosive
vapor, dust or other harmful elements. When a cylinder has
not been used for a period of 4 months, it should be connected
to a pump and fully extended and then retracted a minimum
of 5 times. This cycle will lubricate the cylinder wall, reducing
the possibility of corrosion and damage thereof.
How to remove faulty coupler:
If cylinder does not retract,
1. Secure load by other means.
2. Depressurize pump and hose.
3. Remove the cylinder from application.
4. Disconnect and replace with new coupler.
Important: Do not attempt to grasp with pliers or wrench without
How to bleed air from system:
1. Place pump at a higher elevation than the hose and cylinder.
2. Operate pump to fully extend and retract the cylinder 2 or
back to the pump reservoir.
3. Follow pump instruction m
anual to bleed the air from pump
reservoir. On most pumps, air can escape by opening the
