Partial Maintenance Partial maintenance is performed every 6 months and grouped into 3 core packages: - Safety Inspections - Excerpt from Preventive Maintenance (Part 2) - Image Quality Check

1.3.2

Full Maintenance Full maintenance is performed every 12 months and includes partial maintenance as well. To improve planning and maintenance, the individual tasks have been grouped into 4 core packages as follows : -

Safety Inspections according to EN 62353:2008 Preventive Maintenance (Part 1) Preventive Maintenance (Part 2) Image Quality Check

Each of these 4 packages can be performed independently of the others and includes the complete instructions in the corresponding chapter. This makes it possible to schedule full maintenance over several days. The required work times will be extended in accordance with the corresponding ’Next steps’.

1.3.3

Spirit / Spirit Power and IES of Emotion: Preventive Parts Replacement APC 750VA UPS (P/N: 03806739 and 03806747) and MGE 1500VA UPS (P/N: 07733376 and 07733368) have to be replaced every 2 years beginning with the date of installation. The date for the next replacement has to be documented in the Maintenance Protocol. (Note: MGE 2200VA UPS (P/N: 07735090) and new HenDan 1500VA UPS (P/N: 10049948 and 10049944) are equipped with a long-lasting battery (5 years / 25° C). Therefore, preventive replacement of the UPS is not necessary.)

1.3.4

Checking the drive belt tension NOTE

Emotion (2007) / Spirit

The drive belt tension has to be measured during system installation, each time maintenance is performed, and after replacement of the drive belt. Additional measurements are unnecessary.

Checking the gantry brake NOTE

A loose gantry brake may lead to safety-related risks, e.g., during tube replacement. The gantry brake has to be checked during system installation and each time maintenance is performed on the system.

Follow the steps below to check the gantry brake:

• Switch off the system and secure it against unintended switch on. • Lock the gantry brake. • With a reasonable force, carefully push the HV tank clockwise to check if the gantry disk rotates. ¹ If the disk rotates, the gantry brake has to be adjusted.

Checking the anchoring of the patient table to the floor Checking the anchoring Check the torque of the 4 floor mounting screws:

• The LIEBIG anchors (M8) must be secured with a torque of 25 Nm. Use a torque wrench with a size 13 hexagonal nut.

• The HILTI-anchors (M10) must be secured with a torque of 50 Nm. Use a torque wrench with a size 17 hexagonal nut.

• If you cannot reach the recommended torque, check the floor condition according to "Planning Guide" and the"Installation and Setting instructions". Contact the responsible Project Manager for on-site information.

Checking the horizontal belt tension Checking the belt tension Check the horizontal drive belt tension:

• Move the table forward 1000 +/- 10 mm so that the distance between the tension adjuster and the connection joint is 1000 +/- 10 mm.

• Loosely install a cable tie around the belt and position it approx. in the center of the tension adjuster and the connection joint (1000mm/2 = 500mm).

• Hook a spring scale (100 N) into the cable tie. • Position a ruler or measuring tape in the vertical position next to the cable tie. • Pull the spring scale in the vertical direction with a tension of 25 +/- 1 N and measure the vertical change in distance (see below illustration). ¹ The vertical change in distance must be 62+/-1 mm (at 25 +/- 1 N).
