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 package.

1. Place some wooden battens on the ground and then use a crane to have the packing rack removed on to the battens so as to make its base is of some clearance from the ground.
2. Have the platforms of the lift suspended by a crane and then screw off the upside bolt and remove the first platform on to the wooden battens initially prepared.
3. Screw off the downside bolt and take away the packing rack on both sides.
4. Remove the shock absorption plastic film with a knife.

Step 4: Use a crane to have the general parts positioned in accordance with following layout.(For convenient installation, it would be better to pad something supporting under the platform)
Oil cylinder, steel cable and oil hose have already been fixed in the main platform before packing.
Wire rope, oil hose, safety lock etc, have already been fixed in the beams before packing.

Step 5: Put the four posts on the prior position.

Step 6: Sling the beam and vertical fall into the post, see below attached picture. (It would be better to put something supporting under the beam, about 800mm height.)

Step 7 ：Install the platform and connecting plate

1. Install unlock parts, connecting handle welding 1 and handle welding 2 screw sleeve, following the attached picture,(Note: handle welding 1 and handle welding 2 through the beam and lead to platform)
2. Use hex round head screw M18*100, hex nut M18, flat washer ￠18 to connect the platform, beam, and connecting plate, and insert the block plate. Following the attached picture. (Note: take out the steel cable and through the wheel of beam and lead to post)

Step 8: Install post top plate, Use hex round head screw M12*25, hex nut M12, flat washer ￠12 to fix the top plate, and then tighten the 4 steel cables on the top plate.

Step 9: Assemble the hydraulic power unit and control box.

1. Connecting the air hose and oil hose to hydraulic power unit. Following the attached picture.
2. .Fix control box on the post by 4 cross recess pan head screw. Counterpart connect the control box cable.

Step 11: Adjust the level
Please do not put any car when adjusting the level.
Power on, press the up button after indicator light is on light. Measuring if two platform height is same after steel cable is tight, if not, adjust the steel cable from top post, meanwhile, check the safety lock if available and manual release is available.

Step 12: Install the ramp, place cover A and cover B on the beam and put on the oil pans. (Down the platform to Min when install ramp).

Step 13: Install expansion bolts.

Items to be checked after installation.

OPERATION INSTRUCTIONS

Precautions

1. Check all the joints of oil hose. Only when there is no leakage, the lift can start work.
2. The lift, if its safety device malfunctions, shall not be used.

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.

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.

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.

Yearly checking items

• Empty the oil tank and check the quality of hydraulic oil.
• Wash and clean the oil filter.
  If 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.
