6.2.2. Inspect Hood Gas Springs—Daily

Figure 136. Inspect Hood Gas Springs Daily.

Introduction

Inspecting the Hood Gas Springs daily routine (Figure 136).

Estimated Completion Time

Less than 5 minutes

Procedure

Two gas springs (on the left and right sides of the hood) hold the hood up when open. These

springs must be inspected daily as follows:

 Check to ensure the retaining clips holding the gas springs to the ball joints are present and

secure.

o A missing or defective clip can result in the gas spring coming loose and the hood

falling.

 Check for oil on the shafts of the gas springs and/or on the area of the print head gantries

underneath the gas springs.

o The presence of oil indicates the spring is leaking.

o Leaking springs must be replaced immediately.

 Check that hood does not fall:

o Open the hood all the way and ensure it does not begin to fall (it may rise slightly,

which is acceptable).

 If the hood begins to fall, replace both gas springs immediately.

o Repeat with the hood approximately half way open.

 If the hood begins to fall, replace both gas springs immediately.

 If a great amount of force is required to close the hood the gas springs are defective.

o Replace both gas springs immediately.

 If the hood seems heavy to lift or requires unusual force the gas springs are defective

o Replace both gas springs immediately.
