Lubricating the Gantry Lead Screw
WARNING: Electric shock hazard. Shut off the PS System power
(Turning Off the System on page 4-4) — switch off the main
power switch before removing the lead screw shields.
1. Preparation—
1a. Shut off the PS System power and ensure the main power switch
is in the OFF position.
1b. Remove the screws that hold the Lead Screw Shield to the gantry
rails.
1c. Remove the shield.
2. Remove the old grease and dirt build up from the lead screw
using shop towels.
3. Apply new grease—
3a. Apply NSK Grease (or equivalent) to the lead screw grease fit-
ting using an MG70 (or equivalent) grease gun. See Figure 4-26.
Note: Too much grease may cause grease to splatter inside the work
envelope. Do not over-apply the grease.
