Relief Valve Adjustment
All pumps contain a factory set relief valve to prevent over-pressurization of the system.
Lower pressure settings can be obtained. Contact your Authorized SAM Service Center.
Air Removal
Removing air from the hydraulic system will help the cylinder to advance and retract
smoothly.
Pump With Single-Acting Cylinder (A):
1.
Vent pump reservoir (for vented pumps only) and close release valve.
2.
Position pump at higher elevation than cylinder.
3.
Position cylinder with the plunger end down (up if using pull cylinder). See Figure 3
below.
4.
Operate pump to fully extend the cylinder (retract if using pull cylinder).
5.
Open release valve to retract cylinder (extend if a pull cylinder). This will force the
trapped air to move up to the pump reservoir.
6.
Repeat the above steps as necessary.
7.
Add oil if necessary. See page 10.
8.
Return vent/fill cap to operating position.
