6. Running Hoses And Bleeding The Hydraulic System:
A.
When attaching hydraulic fittings with pipe
threads to the cylinders use Teflon tape. DO NOT start the
Teflon tape closer than 1/8” (3mm) from the end of the fitting.
Failure to comply may cause damage to the hydraulic system.
B.
When tightening connections with
flared (JIC) fittings, always follow the following tightening
instructions. Failure to follow these instructions may result in
cracked fittings and / or leaks.
Use the proper size wrench. The nut portion of the fitting is
the only part that should turn during tightening. The flare seat
MUST NOT turn. Screw the fittings together hand tight. Using
a 11/16" wrench to rotate the nut portion of the fitting 2-1/2 hex
flats.
Back the fitting off one full turn. Again, tighten the fitting hand
tight, then rotate the nut portion of the fitting 2-1/2 hex flats.
C. Connect the long hydraulic hose to the branch on the JIC tee
fitting, Fig 6 (F).
D. Connect a male pipe thread to male JIC elbow to the port near
the base end of each cylinder. The fittings should face toward
the front of the lift (towards conduit or hose guard) and up 5
to 10 degrees, the cylinders will rotate upward as the lift rises,
Fig. 6 (B). For rear approach hose installation face rearward
down 5 to 10 degrees.
E. Connect the short hydraulic hoses to the elbows on the
cylinders, Fig. 6 (B). These connections should be hand-tight
only. Feed the free ends of the hoses thru the hose guides,
Fig. 6 (C & D) . (Ignore for rear approach hose installation.)
F. Connect short hoses to the runs on the JIC tee fitting, Fig. 6 (E).
For rear approach hose installation to stainless tubing also
position tubing clamp adapters over concrete anchors and
place clamp over tubing as shown.
A JIC tee fitting
B JIC elbows
C Short hydraulic hose to be routed over latch release handle
as shown, or by hydraulic cylinder as shown.
D Feed the free ends of the short hydraulic hoses thru the
hose guides as shown.
E Short hoses to be connected to the runs on the JIC tee
fitting.
F Long hydraulic hose to be either routed through 2" conduit
or through the hose guard as shown. This is according to
the installation option chosen by customer.
G Latch release handle
H Hose guard (Note: Hose guards are not to be used if
conduit is in concrete, DO NOT anchor at this time.)

O Swivel Tee

Connect 90 degree JIC elbow to swivel tee and then long hose
to male adapter.
G. With the lift at it’s lowest position loosen the connections
between the hoses and fittings attached to the cylinders.
Do not loosen the connections between the fittings and the
cylinders themselves.
H. Run the power unit until fluid appears at the cylinder ports.
Tighten the hose connections.
I. Add fluid to the system as previously described.
