Yes...but very minimal! Please refer to your owner's manual.
Products are constantly changing, but Greg Smith Equipment should be able to locate most of the popular lift parts for lifts manufactured in the last ten years. Most USA lift manufacturers are out of business...but even though the lifts were "made in the USA"...many of the parts have been coming from China for over 15 years. Many parts are generic...and although the quality of some of the parts may vary from the original manufacturer, the end result should be satisfactory.
The hydraulic system may have "air" in the system and the system needs to be purged. If your lift has a "direct drive" cylinder, raise the carriage about one foot. Do not set the lift on its locks. Locate the allen screw on the top of each column. Open (just a little) ONE allen screw until you feel a small amount of air AND fluid flowing; tighten the screw. Lower the lift and then repeat the procedure for the other cylinder. Repeat if necessary. For other lifts (with different cylinder configurations); raise and lower the lift a few times (with no weight) and hold the dump valve for a few seconds when in lowered position. You can feel the air flowing through the vent hole in the reservoir cap. The hydraulic system is being "bled".
A noise coming from the lift while it is traveling up or down may be caused by a variety of reasons. A certain amount of sound is normal. However, certain sounds are indications that some adjustments may be necessary. The columns need to be perfectly aligned (and level side to side) to ensure that the carriages are not contacting the inside of the column at some irregular angle that may create a vibrating sound. This can be caused by improper installation. The seals inside our cylinders are made to "fit" as tight as possible. On some lifts, there is a "break in period" that is needed to "soften" the seals inside the cylinder. The "stiffer" seals may vibrate or rub against the inside of the cylinder wall until the seal becomes more pliable after using the lift several times. We recommend the addition of four ounces of Caterpillar Hydraulic Oil additive #1U-9891 into the power unit hydraulic oil reservoir to help "speed up" the break in period. This Caterpillar hydraulic oil additive will soften the seals just enough to eliminate the noise, but will allow the seals to maintain their integrity to operate effectively. There may be other factors that would produce some slight noise when operating the lift. The lift experts at Greg Smith Equipment can provide you with many solutions to eliminate much of the noise. Of course, we cannot come to your location to perform these simple procedures, but we figure that if you were competent enough to install the lift, then performing some small noise reduction tasks should be very easy.
