2. Overview of the lift
2.1 General descriptions
This four post lift is generally composed by four posts, two beams, two platforms, a hydraulic oil cylinder and a set of power unit. It
is driven by an electro-hydraulic system. Up and down of platforms is controlled by the to and fro movement of the oil cylinder. To
ensure ultra safety of operators, it is equipped with mechanical safety locks in the four posts, which will be manually engaged in
the process of lifting so as to prevent the platforms from sudden dropping down in case the hydraulic system fails to work.

3.2 Precautions for installation
3.2.1 Make sure the four posts stand paralleled and are vertical to the ground. No slanting.
3.2.2 Joints of oil hose and steel cable must be firmly connected in order to avoid the looseness of steel cable and leakage of oil
hose.
3.2.3 All bolts should be firmly screwed up.
3.2.4 Do not place any vehicle on the lift in the case of trial running.
3.3 Installation instructions
Step1: Choose a proper site
Location requirement
If not specifically stated, our lifts are only for indoor use. It should be fixed on a smooth and solid concrete ground. Do not install
this lift on expansion beams of concrete or on a second or an elevated floor without first consulting building architect. Make sure
that the space around or over the lift should be free of obstructions like heaters, building supports, electrical lines etc.
Step 2: Fix the installation layout
Once the installation site is determined, mark first the standing point of the four posts by a tape measure and chalk. Ensure two
diagonal lines are of the same length.
Step 3: Remove the packing materials.
Step 4: Lay down the main post and assistant post as showed in below picture.
Step 5: Connect the main beam (the one without angle bar) into the posts and lock it on the second lock. Then put both posts up.
Please refer to below picture.
Step 6: Connect the other posts and beams in the same method.

10
Step 7: Position the four posts according to the dimensions show in the picture..
Step 8: Connect the platforms and beams
Connect the assistant platform to the beam. Pay attention that the runway for jack should be placed inside. Mount the car
protection in front of the platform. Connect the other beam in the same way.
Step 9: Mount the top of the post with showed direction.
Step 10: Connect the steel wire and release bar. Release bar should be mounted nearby the engine.

11
Length of wire
1=6800 mm. 2=8265 mm. 3=4140 mm. 4=2670 mm.
Step 11: Mount the hydraulic pump and oil hose onto the main post.
Pull out the oil hose and air hose (if applicable) from the main platform and connect to the hydraulic block.
Then fix the hydraulic pump on to the plate by M10*30 hex bolts, spring and flat washers.
Step 12: Connect the limit switches
The two-wire plug is for top limit switch and four-wire plug for bottom limit. Mount the limit switch according to below
pictures.

12
Step 13: Leveling
No vehicle on platforms when leveling.
Switch on and press the UP button. When the steel cable is been tightened, measure if the two platforms are of the same height
from the ground. If not, adjust the tightening screw fixed on top of the main post. Let the lift goes up and down 2-3 times, so the lift
will go all way up and down, before next step.
Step14: Fix the expansion plug.

6.1 Daily checking items before operation
The user must perform daily check. Daily check of safety latch system is very important –the discovery of device failure before
action could save your time and prevent you from great loss, injury or casualty.
·Before operation, judge whether the safety latches are engaged by sound.
·Check whether oil hose well connected and whether it leaks or not.
·Check the connections of chain and steel cable and check the power unit.
·Check whether plug bolts firmly screwed.
·Check if safety teeth and safety block matched well or not.
6.2 Weekly checking items
·Check the flexibility of moving parts.
·Check the working conditions of safety parts.
·Check the amount of oil left in the oil tank. Oil is enough if the carriage can be raised to highest position. Otherwise, oil is
insufficient.
·Check whether plug bolts firmly screwed.
6.3 Monthly checking items
·Check whether plug bolts firmly screwed.
·Check the tightness of the hydraulic system and screw firm the joints if it leaks.
·Check the lubrication and abrasion circumstance of axial pins, carriages, lifting arms and other related parts and replace in time
with new ones if they failed to work well.
·Check the lubrication and abrasion circumstance of steel cable.
6.4 Yearly checking items
·Empty the oil tank and check the quality of hydraulic oil.
·Wash and clean the oil filter.
Users strictly follow the above maintenance requirements, the lift will keep in a good working condition and meanwhile
accidents could be avoided to a large extent.
