Material and Setup Checks
Questions to settle before site use
What applications can the BK-850 cover?
It is positioned for compatible spraying, grouting, leakage repair and surface-waterproofing work.
Can the BK-850 spray every type of cement mortar?
No. Material suitability depends on the formulation, and the published maximum particle size is 1 mm. Confirm the material before use.
How far can the machine deliver material?
The stated maximum delivery distance is 10 m vertically and 15 m horizontally.
Do the 1300 W motor and 1500 W compressor run at the same time?
The available information lists the two ratings separately but does not confirm simultaneous operation. Confirm the electrical load before planning the site supply.
Check the material and required delivery distance
Share the product formulation, particle size and working height so Boke Tools can assess the BK-850 for the task.
