Installing Gate Opener
IMPORTANT
Read entire section before beginning work.
Air supply must be between 80 and 125 psi (5.5 to 8.5 bar) at
the control valve, not at the air source, for the unit to
operate properly.
CAUTION
!
Do not exceed 125 psi (8.5 bar) air pressure. Excessive air
pressure may cause damage to the Martin®Gate Jack Opener.
Make sure air is filtered and lubricated.
1. See Figure 1. With control valve (A) in closed position, connect filtered
and lubricated 80- to 125-psi (5.5- to 8.5-bar) air supply to control
valve inlet.
2. Retract the dog (B) by moving the release lever (C) until it stops.
3. Place the Martin®Gate Jack Opener over the capstan (D) on the rail car.
With the stirrups (E) pointing down, release the dog into a capstan hole.
