CHAPTER 3 MAINTENANCE PROCEDURES

3.2.1 Variations in Opening Pioneer Models

Turn the balance off and unplug the power cord before you begin.
Preliminary Steps:
For a balance with a Draft Shield:
1. Remove the Draft Shield components from the balance:
–
Remove the top panel: lift its plastic handle and slide it forward to remove it.
(See Figure 3-1.)
–
Remove the side doors: when they are closed, a groove in the plastic door guide
aligns with the tab on the Housing. (See Figure 3-2.) Align the groove and lift
the panel straight up, then out and down to disengage it from the top.
–
To remove the front and back panels, press on the tab in the middle of the top
frame and gently press the panel out.
Figure 3-1. Top panel lifts up and slides out.
2. Remove the Weighing Pan.
For a balance without a Draft Shield:
1. Remove the Weighing Pan and Pan Support.
After completing the preliminary steps, turn the balance over and remove two screws from the
rear, and one near the front, under a plastic sliding tab. Lift off the Top Cover. Then lift off the
Load Cell cover. You now have access to all components of the balance.
