RB-214/215 Core Drilling Machine

7.Frequently check the water level in the vacuum water trap. When water trap becomes half full, stop drilling and empty water.

8.After using, turn drill motor ON/OFF switch to the OFF position, then turn vacuum motor ON/OFF switch to the OFF position, unplug power cord and remove, clean and store vacuum seal.

NOTE! Vacuum can be released by turning vacuum release valve (Figure 2).

Ceiling Jack Anchor Method

1.Cut pipe or wood to the required length to fit be- tween ceiling and ceiling jack screw (Figure 1) on top of mast.

2.Tighten ceiling jack screw to force machine against floor.

3.Stabilize and plumb machine by adjusting 4 leveling screws on base.

Operating Instructions

WARNING!

Do not wear cloth gloves or loose clothing when operating Drilling Machine. Keep sleeves and jack- ets buttoned. Do not reach across the machine. Keep hands and fingers away from drill bits.

Do not use this Drilling Machine if the ON/OFF switch or other controls are broken. Always wear eye protection to protect eyes from dirt and other foreign objects.

Do not use Drilling Machine if it is not securely an- chored.

1.Thread the drilling bit (Figure 4) onto drilling spindle (Figure 1) and tighten securely with bit wrench.

CAUTION Never turn drill ON with bit resting on

the concrete.

2.Check hole alignment by lowering drill until it is about 1/2″ from concrete.

3.Position 2-speed selector knob on drill to desired speed. Move selector down towards spindle to select high speed for up through 4″ bits. Move selector up away from spindle to select low speed for bits

over 4″. Make certain speed is proper for bit diame- ter being used.

CAUTION DO NOT move speed selector while drill spindle is rotating.

NOTE! If a water collector ring and pump is used, plug pump into a properly grounded 115V receptacle. Have suitable container for draining.

4.With water control valve shut OFF. connect water inlet hose to drill and water source.

NOTE! Water can be supplied by a standard garden hose or by a pressure tank. Water is fed through inlet hose, down inside of bit, washing cuttings from under bit crown, up and outside of hole. Be sure that any method used has adequate water pressure to supply a flow of 1-2 gallons per minute. Lack of water can cause diamonds to polish or burn the bit causing bit end to turn blue.

5.With drill motor ON/OFF switch in OFF position, plug power cord into a properly grounded receptacle.

6.Open water control valve allowing water to flow at 1- 2 gallons per minute.

WARNING Before turning drill motor ON, be certain that machine is securely anchored.

7. Turn drill motor ON/OFF switch to ON position.

CAUTION DO NOT apply full load until entire bit crown has penetrated the material.

8.Turn feed handle to apply load on bit. To prevent bit from wandering, apply light pressure on feed handle while starting to drill.

NOTE! The AMP-meter has a green and red area to in- dicate proper pressure and drilling speed, preventing motor overload and providing longer bit life. The green area is the working range; the red area indicates too much pressure being applied. Keep Amp-meter needle in the green area. Too little pressure can polish bit and too much can cause undue wear.

9.Drill bit feed should be uniform without excessive force. Drilling penetration of 1″ to 4″ per minute may be achieved in concrete depending on material and bit diameter. Proper feed pressure is determined by load on motor and reading on Amp-meter. To maximize life of drill bit, regulate feed rate so that needle on Amp- meter is in upper green area of 20 amp range. If needle goes into red area above 20 amps, decrease feed rate as undue bit wear will result.

NOTE! If the cooling water turns clear, it is an indication you are drilling through rebar.
