Check Pulley Cover and Lock Collars: Before proceeding, double check to
make sure the locking shaft collars for the crossrail cable pulleys are tight and
secure. Check the pulley cover (2-RIGHT and 2 LEFT) over the shaft located on
the pulley side of each crossrail. CHECK the pulley and cover are firm against
the locking shaft collar already in place. Check the additional lock collar on the
outside of the shaft is tight and secure. To prevent personal injury or death,
crossrail lock collars must be tight. If they are ever removed - always make sure
the locking shaft collars are tight and secure.
Check the crossrail locking assembly before use. Make sure all bolts and
collars are tight. The assembly is pre-installed from the factory but parts
may come loose during shipping.
After installation is completed, before start up, be sure to inspect and
tighten all bolts.
Start Up:
Make sure power unit reservoir is full with 12 quarts of 10-wt hydraulic

closest to the power unit comes within 1” to the bottom of the lowest lock
position. Tighten the cable-adjusting nut on top of each leg cap until all remaining
safety latches come within 1” to the bottom of the lowest lock position. If cables
are adjusted evenly the lift should be raising level and all four safety latches
engage or audibly click simultaneously.
IF LIFT DOES NOT RISE: Check hose connections. Fluid should be pumping
through the hose. Check fluid level.
NOTE:
There will be some initial stretching of the cables in the beginning. It will
be necessary to readjust the cables a week or so after first use.
Run the lift up and down a few times to make sure that the safety latches is
engaging uniformly and that the safety latch release is functioning properly. Re-
adjust if necessary.
When lowering the lift
PAY CAREFUL ATTENTION. ALWAYS make sure that
all FOUR SAFETY LATCHES are disengaged. If one of the latches locks on
