HYDRAULIC FLUID
•
Remove the vent plug from the top of reservoir. You are going to fill the tank with fluid. Either AW 32 or 46 Hydraulic oil
is good choice. We don't recommend the transmission fluid as it is too thin. The unit will hold approximately 2.64
gallons(10 liters) of fluid.
ADJUSTING CABLES
•
Place a pair of small or medium vise grips around the shoulder of the long threaded adjusting bolt on the cable to
make any adjustments.
•
Use a deep socket to adjust the slack out of the cable. Adjust tension to cables equality.
DO NOT over tighten. Note: If one of the cables is tighter than the other, the carriage will go up uneven.
These
should be tightened like a Banjo String or Fan Belt.
ADJUSTING & SYNCHRONIING THE CARRIAGES
•
One of the most important things to remember is not to tighten down one side more than the other. The key is to
tighten one side a half dozen turns then the opposite side a half dozen turns. After getting both cables equally tight(YOU
SHOULD BE ABLE TO MOVE THE CABLES ABOUT AN INCH BACK AND FORTH WITH SLIGHT PRESSURE
LIKE A FAN BELT OR A BANJO STRING) raise the lift all the way up by pressing the UP Button on the power unit. Do
not bottom the lift out at the top by holding down on the switch.
•
Raise the lift off the latch(lock) by pushing the power button, this will enable you to pull each release cable ring
located at the bottom of both carriages. See Figure 6. Pull down on the lowering valve handle(lever) on the power unit and
lower the lift all the way to floor. Raise the lift again and listen for the clicking of the safety locks in each column.
Determine which side is slower and tighten the adjusting bolt on the opposite side carriage
. Remember to only tighten
a few turns at a time until the both locks click at the same time when raising the lift. Cycle the lift up and down. Repeat the
adjustment until the carriages are within a 1/4
”
of each other or the clicks are almost at the same time with each side. When
cables are adjusted properly they should be fairly tight.
