5.
Position suitable lifting device (4) directly over top of gooseneck cylinder (3). Lower hook of lifting device (4) and
attach end of lifting strap (2) to lifting device (4).
CAUTION
Do not apply too much force when taking up slack or excess pressure will be
applied on upper cylinder pin and removal may be complicated and damage to
equipment may result.
6.
Take up slack in lifting strap (2). Slant lifting strap (2) toward center line of gooseneck lug (1).
7.
Place a drain pan under front edge of platform near cylinder hydraulic lines and valve connection points beneath
platform.
WARNING
Residual pressure may remain in hydraulic lines. Open fittings slowly or injury to
personnel may result.
CAUTION
All fittings and openings must be capped or plugged immediately after opening, to
prevent dirt, moisture, or foreign material from entering the hydraulic system or
damage to equipment may result.
NOTE
Remove small hex fitting from large hex fitting.
8.
Remove screw (5) and block clamp (6). Tag and slowly disconnect three hydraulics lines (7) from three hydraulic
valves under platform. Install protective caps/plugs into valves only.
NOTE
Make sure ends of hydraulic lines are secured to drain pan and are pointing
directly into the drain pan to prevent hydraulic fluid from spraying as the
gooseneck cylinder is compressed. To prevent siphoning, do not allow ends of
hoses to get into hydraulic fluid.
9.
Place ends of hydraulic lines (7) into drain pan and secure to drain pan using duct tape to prevent lines from
pulling out under pressure as cylinder is compressed.
10.
Remove screw (8) and lockwasher (9) if present. Remove bolt (10), lockwasher (11), and washer (12). Discard
