Installer Verification
Compatibility between the lift and the vehicle
The installer shall confirm the compatibility between the lift and the vehicle.
Static Test
Deformation
The unladen platform is positioned mid-way between ground level and vehicle floor level and
measurements are taken of the height of the platform and its angular attitude relative to the vehicle floor.
A load of 625 kg is applied to the platform and subsequently removed.
By repeating measurements of the height and attitude of the platform, verify that no permanent
deformation has occurred in any part of the lift or its attachment to the vehicle which could affect the
function of the lift.
Drift
A load of 625 kg is applied to the platform, positioned at floor level. Measurements are taken of the
height of the platform and its angular attitude relative to the vehicle floor. These measurements are
repeated after a 15 minute test period.
Verify that the vertical drift of the platform between the two measurements has not exceeded 15 mm.
Verify that the angular drift of the platform between the two measurements has not exceeded 2º.
Test to Verify that the Lift Cannot Lift Excessive Load
A load of 625 kg is applied to the platform, positioned at ground level. Actuate the UP control and verify
that the platform does not lift (tilt is permissible).
1. Lower platform to the ground.
2. Place 625 kg at center of platform.
3. Press UP switch and verify platform does not lift (tilt is permissible).
4. If platform does not lift, proceed to Dynamic Test. If platform does lift, proceed to step 5, pump relief
valve adjustment is necessary.
5. Access relief valve (see illustration on following page). Loosen 9/16" hex nut on the relief valve
adjustment screw (do not remove hex nut).
6. Turn adjustment screw counterclockwise1/8 turn.
7. Press UP switch and verify platform does not lift (tilt is permissible).
8. If platform does not lift, tighten 9/16" hex nut (do not turn relief valve adjustment screw while
tightening hex nut). If platform does lift, repeat steps 6 through 8.
