Lever on the lifter must be in the LOCK position (left). Pump the
handle.
To LOWER the T-Boom
, the Lock/Release lever on the lifter
must be in the RELEASE position (right). Patient’s weight will slowly
lower the T-Boom.
STEP 4

(2) A-Frames are centered over the patient. Lower the T-Boom and
attach the A-Frame hooks into the Stretcher holes. Move the lever
into the LOCK position. DO NOT EXCEED THE MAXIMUM
CAPACITY OF 400 LB/ 181 KG.
STEP 5
: When the Stretcher is securely attached, pump handle until
the patient is raised just enough to clear the bed and any linens, etc.
Weigh patient and when finished, lower back on to the bed by moving
the Lock/Release Lever to RELEASE (right). Patient’s weight will
lower the Stretcher slowly. Unhook the Stretcher and again raise the T-
Boom so the patient can be safely moved.

TRANSPORT PATIENT VIA THE SCALE!
STEP 6
: It is recommended that you re-zero before each weighing to ensure optimal accuracy.

design, these components are weight sensitive and any interference will affect the accuracy of the
weight data.
