Dynamic Test
With 500 kg applied to the platform, verify that the lift is able to operate throughout its full range of
normal lifting and lowering.
1. Lower platform to the ground.
2. Place 500 kg at center of platform.
3. Press UP switch and verify that the lift is able to operate throughout its full range of normal lifting and
lowering movements.
4. If platform is able to operate throughout its full range of normal lifting and lowering movements, no
adjustment is necessary. If platform does not lift, proceed to step 5, pump relief valve adjustment is
necessary.
5. Access relief valve (see illustration below). Loosen 9/16" hex nut on the relief valve adjustment
screw (do not remove hex nut).
6. Turn adjustment screw clockwise 1/8 turn.
7. Press UP switch and verify lift is able to operate throughout its full range of normal lifting and
lowering movement.
8. If lift does not operate throughout its full range, repeat steps 6 through 8. If lift does operate
throughout its full range, tighten 9/16" hex nut (do not turn relief valve adjustment screw while
tightening hex nut).
Test of Operations and Safety Functions
All functions of the lift and operations of all safety devices are verified after the static and dynamic tests
have been completed. These tests do not apply to pipe break valves nor non-resettable safety devices
such as electrical fuses (These items are the subject of a manufacturer’s type test).
