7.12 Using the Safety Prop 

1)  Elevate the platform a specified height above 

the ground (for elevation height, refer to the 

following table). 

Table 10 - Safety Prop Deployment Height 

Model 

Height   

AS1932 

7.9ft (2.4m) 

AS2646 

10.5ft (3.2m) 

AS3246 

2)  Lift the safety prop, move it to the center of 

the scissor cross tube and rotate it upward 

until it is vertical. 

3)  Lower the platform height until the safety 

prop completely contacts the shaft tube. 

Keep the platform away from the movable 

parts during the lowering process. 

!

Danger 

Do not carry any load in the platform 

when the safety prop is in use. Do not 

use the safety prop for a period longer 

than 8 hours.

 

7.13 How to Stow the 

Guardrail 

On model AS1932, the platform guardrail system 

consists  of  a  folding  guardrail  on  an  extended 

platform  and  a  folding  guardrail  on  the  main 

platform. 

1)  Fully  lower  the  platform  and  lock  it  into  the 

extended platform. 

2)  Remove the platform controller.   

3)  Remove  the  M-shaped  fixed  seat  between 

the  guardrails  on  the  main  platform  and  the 

extended  platform  from  the  inside  of  the 

platform and place it in the platform. 

4)  Remove one solid retaining pin from the right 

front  part  of  the  extended  platform  and  fold 

the  right  guardrail  of  the  extended  platform 

inward.  Do  not  place  your  hands  in  places 

where there may be a pinch point. 

5)  Remove one solid long retaining pin from the 

left  front  part  of  the  extended  platform  and 

fold the left guardrail of the extended platform 

inward.  Prevent  the  front  guardrail  of  the 

extended  platform  from  tilting  over.  Do  not 

place your hands in places where there may 

be a pinch point. 

6)  Fold  the  front  guardrail  of  the  extended 

platform  inward.  Do  not  place  your  hands  in 

places where there may be a pinch point. 

7)  Install the two solid long retaining pins which 

were removed back to the guardrail on each 

side. 

8)  Remove  one  solid  long  retaining  pin  on  the 

top right of the door guardrail.   

9)  Tilt  the  rear  guardrail forward.  Do not  tilt  the 

left and right guardrails together. Do not place 

your  hands  in  places  where  there  may  be  a 

pinch point. 

10)  Reinstall  the  lock  pins  onto  the  guardrail 

bracket on every side. 

11)  Fold the left and right guardrails of  the main
