The Treadly can be used with the handrail raised, or with the handrail lowered for use under a desk. Using the hydraulic handrail can be done easily and without much effort. You can lift the handrail for our Treadly 2 models by turning the “lock switch” on both the left and right sides of the handrail to the UNLOCK position and gently pull the handrail up. To lower it, turn the switch to the LOCK position and gently pull down (in locked mode, the red locks will point towards the rear part of the Treadly).
