Troubleshooting Lift Arm Lock Disengagement
⚠ WARNING Avoid excessive Shim heights! A new concrete cutout and steel reinforced pour are
recommended to correct out of level conditions in excess of 3°.
Some floors with excessive out of level conditions may require Shim heights that reach or exceed
.5 in. / 12.7 mm. When the Shim Height reaches this level, the Lift Arm Lock Pins may not function to
disengage the Lift Arms when completely lowered. To correct this condition, the Arm Lock Pins include
an M12 x 1.75 internal thread, approximately 12 mm deep. A mating M12 Hex Head Bolt with Lock
Washers, or a backing nut (not supplied) may be used to extend the contact point of the Arm Lock
Pins. Adjust the Bolt head position to disengage the Lock as required. Refer to the figure below.
