Section 4
Maintenance
Introduction
Hypertherm assumes that the service personnel who perform the troubleshooting testing are high-level electronic service
technicians who have worked with high-voltage electro-mechanical systems. Knowledge of final isolation troubleshooting
techniques is also assumed.
In addition to being technically qualified, maintenance personnel must perform all testing with safety in mind. See Safety
on page 13 for more safety precautions.
Lifter routine maintenance
The control module and HMI do not require routine maintenance.
On the lifter, the bearings of the ball screw have permanent lubrication and do not require in-service lubrication under
normal operating conditions.
Carriage
The carriage on the slide within the ArcGlide lifter requires lubrication at regular intervals that are based on the number of
hours of operation or the distance that the slide travels.
Under normal operating conditions, the slide should be lubricated every 500 hours of operation. You can find the Total
Lifter Operation Hours parameter on Screen 12 on the ArcGlide control module.
To lubricate the carriage:
1. Remove the side shields and side panels to access the carriage.
2. Locate the funnel-type lubrication nipples (DIN 3405-D3) on either side of the carriage, as shown in Figure 44.
