7.12.1 GENERAL CHECKS
Make sure all pins and bolts to insure proper mounting.
Make sure the chain for proper installation.
Make sure the electrical system feeding voltage is equal to that specified in the nameplate on
the motor, the electric system connection in conformity of the electric plan shown as the
electric diagram (fig. 6) and for proper grounding.
Make sure the lift is connected to the ground.
Particularly, below checks must be followed:
7.12.2
MECHANICAL SAFETIES FOR PROPER INSTALLATION
Check to make sure that safeties will properly engage by pushing the locking button and can be
released properly but pushing the lowering button.
When raising the carriages, listen to the safety hook fall into the safety rack. If not, check the
cause if necessary.
7.12.3
HYDRAULIC SYSTEM FOR PROPER OPERATION
Proper oil level in the tank, refill if needed.
Raise the carriage to the full height and keep the motor running for 5 seconds.
Check all hoses connections to make sure no leakage. Tighten the connections or reseal if
necessary.
Check the carriage for reaching its maximum height.
Repeat the air bleeding of cylinders if necessary.
7.12.4
LIMIT SWITCH FOR PROPER OPERATION
Check to make sure the top limit switch for proper operation. Verify that the power unit stops
working when the carriages reaches the maximum height.
Check to make sure the safety height limit switch for proper operation. Verify the power unit
stops working when the carriage is lowered at about 200mm high.
7.13 ANCHORING COLUMNS
If the lift is chosen to be anchored to floor, the concrete slab should have the
compression strength of at least 3000 PSI and the minimum thickness 160mm
with an extension of at least 1.5m from anchoring point.
The anchor bolts can be ordered from the manufacturer.
Using the base plate as guide, drill each hole in the concrete approximately 160mm deep with
the rotary hammer drill D.20. To assure full holding power, do not ream the hole or allow drill
to wobble.
