Securing Machine
WARNING!
Drilling machine must be properly secured to the work surface to prevent serious injury to the op- erator.
Movement during drilling will cause chatter of bit against work surface, fracturing diamonds. Bit may also bind in hole causing damage to the bit. Vacuum Anchor method should not be used to mount machine to a wall.
Bolt Anchor Method-to-Floor
1.Measure distance from center of anchor bolt slot in base (Figure 2) to center of drill spindle (Figure 1).
2.To locate the anchor bolt hole, use the distance ob- tained in Step 1 and measure from the center of the hole that is to be drilled.
3.Drill and set 1/2″ anchor bolt. Place Drilling Machine over anchor hole and hand tighten anchor bolt.
4.Adjust 4 leveling screws (Figure 1) to stabilize base and plumb mast. Secure machine by tightening an- chor bolt.
Bolt Anchor Method-to-Wall
Use the same bolt anchor method procedure to anchor as above.
WARNING Also fasten a chain to the Core Drilling Machine and secure the chain to prevent the machine falling and causing serious injury.

Vacuum Anchor Method-to-Floor
(RB-214 Only)
The Vacuum Anchor Method is recommended for 8″ diameter holes or less. The Anchor Vacuum Method is NOT recommended on rough or cracked floor conditions, holes deeper than one bit length, or steel concentration greater than standard rebar.
WARNING Do not use Vacuum Anchor Method to mount machine to a wall.
1.Turn machine on its back and insert vacuum seal (Figure 3) under machine base, inspecting first to en- sure seal is in good condition and sealing groove is clean.
2.Turn Drilling Machine
3.Plug power cord into a properly grounded recepta- cle and turn vacuum pump ON/OFF switch to the ON position.
4.Insert vacuum slot cap into anchor bolt slot (Figure
2)and check vacuum and hose connections. Vacuum gauge (Figure 2) must read a minimum of 20″ of mercury.
5.The drilling machine should now be vacuum anchored. If machine does not anchor, add weight by standing on vacuum base. It should now anchor with vacuum gauge reading 20″ of mercury minimum. If not, check the floor and vacuum seal (Figure 3) for leaks.

6.Adjust 4 leveling screws to eliminate rocking and to stabilize machine and plumb mast. The machine is now ready to drill.
