5.1 Preparations for initial operation
Before switching on make sure that all existing protective housings
are mounted and that the filter unit is connected correctly.
All persons in the proximity of the machine must wear ear
protectors, safety glasses with lateral protection as well as safety
shoes. The operator is obliged to wear close-fitting protective
clothing.
Handle all plugs, cables, hoses and operating devices with care.
Avoid any contact with live wires.
Works on the electrical system must only be carried out by qualified
specialists.
Check the surface to be treated for loose parts (stones, screws, etc.).
The surface must be swept if necessary. Make sure that the machine
can travel over all inequalities on the surface. Small inequalities like
weld seams or floor joints are no barriers for the machine.
Regular inspection is important in order to avoid downtimes. Carry
out the following checks before any start-up:
; Check whether all machine parts are assembled safely and
correctly.
; Check all screws and other fasteners for tight seat.
; Check the abrasive storage hopper, the feed spout and the blast
wheel parts for foreign bodies and remove them.
; Check the blast wheel blades, impeller, control cage, liners and
fastening screws for damages and wear.
Wear will take place in the form of grooves worn into blades along
path taken by abrasive from center of blastwheel outwards. Wear
grooves are acceptable until 75% of blade thickness has been
worn away. When this point is reached, replace all blades as a
set.
; Check the front, side and rear seal systems and brush seals for
wear.
