DUST WARNING

Cutting, especially when DRY cutting, generates dust that comes from the material being cut, which frequently contains silica.
Silica is a basic component of sand, quartz, brick clay, granite and numerous other minerals and rocks. Exposure to excessive amount of such dust can cause:

• Respiratory diseases (affecting your ability to breath), includ- ing chronic bronchitis, silicosis and pulmonary fibrosis from exposure to These diseases may be fatal;

• Skin irritation and rash; and

• Cancer according to NTP and IARC

• National Toxicology Program, International Agency for Re- search on Cancer
  Take precautionary steps

  • Avoid inhalation of and skin contact with dust, mist and fumes;
  • Wet cut when feasible, to minimize dust;
  • Wear and ensure that all bystanders wear appropriate re- spiratory protection such as dust masks designed to filter out microscopic (See OSHA 29 CFR Part 1910.1200)

California Prop 65 Warning: Use of this product can cause exposure to materials known to the State of California to cause cancer and/or birth defects or other reproductive harm.

OPERATION

Friction Clutch

Clutch provides protection under high-load mechanical condition for operator, machine and bit. Do not exceed 3-4 second of clutch engagement, as it will cause excessive wear on the clutch plates.
Master Switch and Overload Protective Device

After pressing on switch, machine should start smoothly, If load is not reduced after several seconds, switch will shut off automatically. Start again if remove load, machine will again start smoothly.
To improve the efficiency of drilling, some machines have 3 speed gear box.
Select a gear that is appropriate for the load, material and bit size.

Extension Cords

Do not use the tool if the cord or plug is damages. IF damaged, have it repaired by an authorized service facility before use. If the plug will not fir the outlet, have a proper outlet installed by a qualified electrician. The use of a circuit protected by a ground fault interrupter (GFCI) is highly recommended. Use extension cords of the proper cable size, referring to the following chart

Never use a extension cord smal ler than shown in the chart. Be sure your extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified electrician before
using it. Protect your ex1ension cords from sharp objects, excessive heat and damp or wet areas.
Using an extension cord with inadequately sized wire causes drop in voltage, resulting in loss of power and possible tool damage.

SECURING THE RIG: RECOMMENDED METHODS

A. USE A CONCRETE ANCHOR. Use either a 1/2 or 5/8 concrete anchor to secure the base to the work surface. Always be sure to level the rig and tighten the lock nuts on the leveling screws before tightening the anchor. Manta base should be secured using a concrete anchor. Insert bolt through the washer plate then into slot located on the base and then tighten the bolt firmly in the anchor. Follow concrete anchor manufactures instructions

It is essential to always secure the rig to the work surface to help prevent personal injury and also to protect the rig. An unsecured rig could rotate during
drilling and possibly cause injury. It could also cause the bit to chatter against the work surface or bind in a hole, which can fracture the diamond. Always test the anchor for firm attachment before drill ing.

DRILLING SPEEDS

Specifications for the different motors are listed in the table below.
NOTICE: Change the gears only when the motor is off.
All building materials and work surfaces are composed of aggregates of various size. Aggregates are materials such as gravel or crushed stone. The size of the grains and the hardness of the material
affects the speed of drilling. Most building materials contain some type of steel reinforcements. All bits are designed to cut through these types of reinforcing steel. However, bits should
never be used for drilling solid steel plates. Proper selection of the diamond core bit should be based on material to be drilled and performance requirements.

WATER SUPPLY

An adequate supply of clean water is necessary for drilling. Connect the water supply hose to the hose fitting on the output of the core drill motor. Take precautions that the water supply wi ll not be interrupted during the drilling operations.
NOTICE: If a bit is run dry it can be ruined in a few seconds.

• Thread anti-clockwise to attach core bit.
• Thread clockwise to loosen.

DRILLING PROCEDURE

When drilling through concrete floors, the core will generally drop from the diamond bit. Caution should be provided for people and property below the drilling area.

1. Ensure that you have read and fully understand the complete operation of the Core Drill you have purchased prior to commencing drilling operations.

2. Select and install a diamond core bit appropriate for the job.
   NOTE: Grease the bit threads to help prevent the bit from seizing on the spindle due to surface corrosion.

3. Select either high or low gear speed according to the chart in the Drilling Speeds section of this manual. (Do not shift speed when motor is on.)

4. Connect water hose to water swivel.

5. Secure the rig as described in the Securing the Rig section of this manual.

DEEP DRILLING

When drilling holes that are longer than the core bit, follow the steps below.

1.  Begin drilling the hole as usual. When you have drilled to the length of the bit, retract the bit from the hole and turn off the motor and water as usual.
2. Break off the core by driving a chisel or slender wedge into the circular kerf. Remove the core using core tongs, bent music wire or anchor bolts.
3.  After removing the core, insert the bit carefully into the hole, attach a bit extension to the bit and core drill rig, then continue drilling as usual.

MAINTENANCE

Clean the machine with a dry or moist rag and not with a jet of water. Make sure that no water gets into the motor or the switch box. Ensure that the ventilation slots are always clean. Clean and greases the tool thread reguarly.

Oil bath gear

The gear oil should be changed after 300 hours of operation. Ensure that this work is carried out in a specialist workshop, or proceed as follow: Clamp the machine vertical- ly in the vice. Remove the three hexagon socket screws. Take off motor and inter-me- diate cover. Change gear oil use only original oil. The filling quantity is 300-310ml.To reverse disassembly procedures
ATTENTION: if gear oil escapes, stop the machine immediately. Leakage of oil dam- ages the gear.

Water connection

If water escapes from the overflow hole on the water connection ring, the rotary shaft seals must be replace immediately. This should only be done in an authorized specialist workshop.

Carbon brushes

The carbon brushes should be examined for wear after about 300 hours in operation, and replaced if necessary. As with all other work on the motor, this should only be carried out by an electrician.
