TEST RUN
1. ADJUST SYNCHRONIZING CABLES
Carriages must be on first set of locks. Use vise grips to hold the cable fitting, meanwhile, use a wrench to tighten the cable nut. Make sure
the two cables have the same tension so the carriages lift at the same time.
If the carriages do not synchronize when lifting, please read below
a. Press UP button to lift the carriages up to the position where the first safety lock of one carriage is higher than the safety lock on the
column. Lower the lift until the lower of the two carriages makes contact with the safety lock on the column.
b. Loosen the safety lock cable. Release the safety lock on the side where the carriage is in the higher position. The other side of the safety
lock should be engaged at this time. Then lower the lift and the side with the carriage in the lower position will remain locked in the same
place and the other side (higher side) is unlocked. Continue to lower down the lift until the higher carriage is at the same level as the
lower carriage.
c. Loosen the jam nut on the higher carriage synchronizing cable and tighten the tension nut until the synchronizing cable has the same
tension as the other synchronizing cable. Tighten the jam nut and safety cable
2. ADJUST THE LOWER SPEED (ONLY FOR ATLAS POWER UNIT)
You can adjust the lowering speed of the lift if needed. Loosen the locking nut on the throttle valve and turn the throttle valve clockwise to
decrease the lowering speed or counterclockwise to increase the lowering speed. Do not forget to tighten the locking nut after the lowering
speed adjustment has been done.
Note: This procedure must be done with a load on the lift.
