There are three movable blocks at the front side of four-post lifting platform. To carry out four-wheel
alignment, take off the movable block of 540mm long and put the turntable here. According to the length
of the vehicle body, adjust the position of other two movable blocks. Next, adjust the position of the
turntable to make the central vertical line of the front wheel coincide with the center of turntable. Then,
take the locating pin out of the slip plate of the platform and turntable and make the vehicle in a free state
at the horizontal direction. Adjust the center of the steering wheel and fix it, install the head of the locator
on the wheel. Adjust the levelness of the head of locator and then adjust the toe-in of the wheel, etc.
Chapter 5 Maintenance
5.1 Maintenance
Pay attention to following points in routine maintenance of the four-post lift:
A. Keep the equipment clean. Do not place foreign matters on the platform and under the
equipment so as to prevent from falling, squeezing and dropping during lifting or causing
damage to equipment and personnel.
B. Keep the hydraulic, electric pipe and circuit clean to prevent circuit from getting aged and
damaged.
C. Replace the hydraulic oil once every 9
～
10 months. To discharge oil, empty the old oil. To fill
oil, let the oil level reaches the middle of the oil scale. Frequently check the oil level. If the oil
level is lower than the required scale, timely replenish oil to the middle position. Foreign matter
is not allowed to drop into the oil tank so as to avoid damaging the oil pump.
D. Clean the oil filter each quarter. Wash with kerosene and sweep the foreign matter on the surface
with brush. Do not damage the oil filter. Once found damaged, timely replace it.
Frequently fill lubrication grease on the steel rope and pulleys in order to prolong the useful life of
relevant parts.
E. Check whether the fastening screw at each position is loose or not every half month; especially
whether the expansion bolts behind the soleplate of the upright post are fixed or not; whether the
nuts of the four large sliding wheel spindles under the primary platform are loose or not.
F. Check whether the upright post is vertical or not every six months. If the verticality changes and
needs readjustment, tighten the nut with tightening torque of about 80N.M.
