Jib Lockout Valve Inspection & Adjustment Instructions - Efco SWAPLOADER SL-222 Parts And Operation Manual

ADJUSTMENT
If after inspecting all mast lock components and making any necessary repairs the gap between
the mast lock and latch bars on the pivot joint is still incorrect, then an adjustment will need to
be made. Please complete the following steps:
1. Retract the jib until the cylinder completely bottoms out (fully retracted).
2. Inspect gap between mast lock latch and the latch bar on the pivot joint. Look for a
clearance of approximately 1/4" (if not proceed to steps 3-5).
3. Loosen jam nut on the adjustment bolt.
4. Turn adjustment bolt; counterclockwise to increase gap or clockwise to decrease the
gap.
5. Once the 1/4" clearance is achieved, tighten the jam nut. Make sure to hold the
adjustment bolt from turning when tightening the jam nut.
JIB LOCKOUT VALVE INSPECTION & ADJUSTMENT INSTRUCTIONS
All SwapLoader hook-lift
hoists have a jib lockout
valve to prevent
accidental operation of
the telescopic jib, while
the hoist is up in a dump
mode. Because the jib
lockout valve can block
the flow of hydraulic oil to
the jib cylinder, should
the valve come out of
adjustment the telescopic
jib may experience a reduction in extension or retraction speed to the point of stalling out.
INSPECTION
When a noticeable loss in extension or retraction speed of the telescopic jib is experienced, the
first step should be to inspect the jib lockout valve and valve mount ramp to ensure that they are
adjusted properly and in good working order. The jib lockout valve is located on the inside rail
of the hoist mainframe approximately two-thirds of the way back on the driver side of the hoist
(see Jib Lockout Valve Mount Detail on Pg. 5-2 of the Parts Section of the manual). Visually
inspect the jib lockout valve roller and the condition of the valve ramp on the hoist pivot joint
without a container on the hoist (see illustration on the next page); this is most easily performed
with the hoist back in a dismount mode. If either part shows signs of wear or damage, then
replace or repair as needed.
With the jib lockout valve roller and valve ramp in good condition the next step is to check that
the valve is positioned correctly with respect to the valve ramp. While looking at the roller end
of the jib lockout valve, notice that the roller moves in and out. With the hoist pivot joint in the
down position, or horizontal to the hoist main frame, the valve ramp should be in contact with
