HON 512 with HON 650 pilot user manual
Crush and impact hazard posed by components falling or toppling over
accidentally.
When working with heavy components that have been removed or are yet to be installed,
injury may result if the components start moving in an uncontrolled manner, e.g., fall down
from the working surface or topple over.
 Place removed components exclusively on level, horizontal working surfaces with enough
load-bearing capacity.
 If necessary, secure removed components so that they will not fall or topple over.
 Wear the required personal protective equipment.
 Exercise caution when performing the relevant tasks.
Risk of injury due to improper lifting
When lifting and handling device components, the weight of the components and assem-
blies can result in injury, especially in the torso area.
 Make sure to always have enough people lifting heavy device components (guideline
using metric units: 15 - max. 55 kg / guideline using imperial units: 30 - max. 120 lbs, de-
pending on age and gender). Comply with all the occupational health and safety regula-
tions and instructions that apply at the installation location!
 Use suitable hoisting equipment and slings in order to handle heavy device components.
Make sure to take into account the device components' center of gravity and to attach
the slings only to the secure device component locations intended for this purpose.
 Wear the required personal protective equipment.
The maintenance described below is meant for devices with design 2 and nominal inlet sizes
of DN 150 – DN 250, and uses the DN 150 Class 600 model without an expander and noise
reduction as a reference. Device models (see page 10)
Refer to the spare parts lists in the appendix (see page 152) to make sure that you replace all
the maintenance parts relevant to your device model during maintenance.
