Warning : When using electric tools, basic safety precautions should always be
followed to reduce the risk of fire, electric shock, and personal injury including
the following :
1. Know your Core Drilling Machine. Read Operator's Manual carefully.
2. Servicing. Other than routine maintenance should be performed by an author-
ized service representative.
3. Accessories; replacement parts. When servicing use only identical replace-
ment parts. Use recommended accessories.
4. Keep work area clean. Avoid cluttered work areas.
5. Consider work area environment.
- Don't expose power tools to rain.
- Mop up all excessive water around the work area before proceeding.
- Keep work areas well lit.
6. Use extreme caution when drilling through floors. Provide for protection of
all personnel and material below the area.
7. Keep visitors away.
8. Don't force tool. Drill should be used at a speed and feed rate that does not
overload the motor. When starting Bits, do not use more than two 12" exten-
sions.
9. Dress properly.
- Do not wear loose clothing or jewelry. They can be caught in moving parts.
Rubber gloves and non-skid footwear are recommended when working
outside.
- Wear protective hair covering to contain long hair.
10. Use safety glasses.
11. Don't abuse cord. Never carry tool by cord or yank it to disconnect from
receptacle. Keep cord from heat, oil and sharp edges.
12. Secure Drill Stand. Use bolts, ceiling jack, or vacuum hold-down. Do not
secure Drill Stand with a vacuum hold-down when drilling on vertical surfaces
such as walls.
13. Don't overreach. Keep proper footing and balance at all times.

Handle to prevent Feed Handle from revolving due to weight of Drill.
SET UP INSTRUCTIONS FOR SECURING MACHINE
Caution: It is very important that the Drilling Machine is properly secured to
the work surface. Movement during drilling will cause chatter of Bit against the
work surface, fracturing diamonds. Bit may also bind in hole causing damage
to the Bit. The methods for anchoring are as follows :
Bolt Anchor Method-to-Floor
1. Mark the position where Anchor Bolt hole will be drilled.
2. Drill and set Anchor Bolt. Place Drilling Machine over anchor hole and
hand tighten bolt (fig. 1).
3. Adjust 4 Leveling Screws (Fig. 1A, 2A) to stabilize Base and plumb Mast.
Secure Machine by tightening Anchor bolt.
Vacuum Anchor Method-to-Floor
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.
RB-208-3
1. Turn Machine on its back and insert Vacuum Seal (Fig. 3) under Machine Base.
2. Turn drilling Machine upright and loosen 4 Base Leveling Screws.
3. Check vacuum and hose connections (Fig. 4, 5, 6), then switch on
vacuum pump.
4. 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 inches of mercury minimum. If not, check the floor
and Vacuum Seal for leaks.
5. Adjust 4 Leveling Screws to stabilize machine and plumb Mast.
The Machine is now ready to drill.
