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. Refer to the Safety section for operating precautions and warning formats.
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. The Total Lifter
Operation Hours parameter on screen 12 on the control module records the hours of operation.
To lubricate the carriage:
1. Remove the 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 the following
illustration.
3. Load a small grease gun with a needle-type adapter with lithium base grease (KP2K, consistency class NLGI 2 is
recommended*).
4. Inject 0.7 g of grease into one of the lubrication nipples. You do not need to lubricate the carriage on both sides.
* To lubricate with a hand press, weigh out the quantity of grease in each stroke.
