    One Year Limited Warranty for Mobi-Jack Hydraulic Equipment

Maintenance

  1. Inspect hoses and connections daily. Replace damaged components immediately with BVA Hydraulics Replacement Parts only.
  2. Tighten connections as needed. Use pipe thread sealing compound when servicing connections.
  3. Always use clean, approved hydraulic fluid and change as recommended or sooner if the fluid becomes contaminated (never exceed 400
    hours). Follow pump manufacturers instructions for changing and adding hydraulic fluid. Use only good quality hydraulic fluid. We recommend
    Mobil DTE13M or equivalent when using with hand pump or air pump; BVA Hydraulics Oil (F01) or equivalent when using with electric pump.
    Never use brake fluid, transmission fluid, 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 hydraulic connections. Teflon tape can be used if only one 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

  1. Keep cylinder clean at all times.
  2. Any exposed threads (male or female) must be cleaned and lubricated regularly, and protected from damage.
  3. Lubricate with light machine oil.
  4. 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.
  5. 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 rst wrapping the jaws of such tool with rags or similar padding.
  • How to bleed air from system:
    1. Place pump at a higher elevation than the hose and cylinder as shown in Figure 2.
    2. Operate pump to fully extend and retract the cylinder 2 or 3 times. The objective is to force the air
    bubbles up hill and back to the pump reservoir.
    3. Follow pump instruction manual to bleed the air from pump reservoir. On most pumps, air
    can escape by opening the oil ller plug/screw.
