Regular Inspection and Cleaning

Daily inspection it the first line of defense against costly breakdown s and unsafe conditions. Begin each shift with a visual check of te entire machine.

Kenőanyag és Fluid Management

Hidraulikus szsztim

A hidraulic system powers the roof bolting machine 's drill rotation, feed, and tramming functions. Use only the connectitás grade and type specified by the OEM. Contaminated oil it the leading cause e of pump and valve failure. Sample hydrasulic oil every 500 operating hour and send for frestrasti dault and watt concents content s contrents.

Short- Term Storage (1- 7 nap)

Park the machine on a leel surface awaye from actife traffic. Cycle the boom and drill head to relieve hydrulic pressure. Wise down exposeed cylinder rods with a rust inhibior spray. Disconnect the battery if the machine wil bet started. Cover the operator 's station to protect prechs from dust and hidrasure.
