Safety Precautions; Oven; Gantry; Z Stage - Stratasys Fortus 900mc Operation And Maintenance Manual

SAFETY PRECAUTIONS

The following components and areas of the printer are potential safety hazards. Take adequate precautions
when using and maintaining the printer.

OVEN

Warning: Always wear safety gloves and long sleeves when working inside the
oven. Components are hot.
The oven temperature is extremely hot. The oven temperature is controlled by a
safety thermostat that shuts the printer off when temperatures reach 260°C
(500°F).
Note: Opening the oven door removes power to the oven heaters.

GANTRY

Warning: Never wear a tie, loose clothing or dangling jewelry when working
around moving components of the system. Beneath the top cover of the system
is the XY Gantry. This area houses the mechanical drive components of the X
and Y axes. Use extreme caution whenever accessing this area of the system.
The servo drive system is extremely powerful so care must be taken. The servo
motors are disabled when the oven door or top covers are opened. The XY
pinch hazard between the timing belts and pulleys is minimized by locking the
hood while building and disabling the motors when the top hood is open.

Z STAGE

Warning: Never wear a tie, loose clothing or dangling jewelry when working
around moving components of the system. The Z-Stage and Z-Stage servo motor
can cause severe injury. The Z-Stage crushing hazard is minimized by locking
the door during Z-Stage movement and disables the Z-Motor when the door is
open.

GUARD DOOR INTERLOCKS

Interlock switches are used to communicate the status of the oven door and the two top slide covers. For safety
reasons, the oven door and the slide covers must be closed before the X, Y, and Z motors will operate.
