Electric Core Drill with Base
Water Connections
The water pressure should not exceed 3 bar (43PSI). • Always
ensure that the tool is operated with sufficient water supply, as
the seals can be damaged if run dry. This could lead to leakage of water into
the gearbox housing – if you detect any water leaking from the gearbox, do
NOT use the tool until it is inspected / repaired at an authorised service centre.
• When drilling "over-head", use appropriate methods and precautions for water
collection to prevent the tool from getting wet.
The tool is equipped with a water supply connection for cooling and lubricating
the drill bit. The water supply is equipped with a connector for hose coupling.
Connect the tool to a suitable water supply or pressurised vessel. Use the tap
lever regulate the water flow rate.
Fastening the Base
It is essential to secure the tool base to the work
surface to help prevent injury and to protect the
tool. An unsecured tool could rotate during drilling, cause the bit to
chatter against the work surface or bind in the hole, which can
fracture the diamond segments.
Use either a ½" or 5/8" masonry anchor to secure the tool base to
the work surface. Always be sure to level the tool base using the
adjustment bolts at each corner of the base so the drill bit contacts
the work-piece squarely and cuts straight.
Insert the securing bolt through the slot in the base and tighten the
bolt firmly.
Overload Protection
The tool is equipped with electronic overload protection, designed to protect the operator, motor and drill bit.
In the event of overload due to excessive forces or strain on the motor, the motor will be automatically
switched off. Allow the motor to cool before using the tool again.
Drilling Guidelines
•
Adjust the flow of water to fully flush material from the bore hole.
•
If "mud" is depositing around the bore hole, increase the water flow.
•
Ensure the drill bit is securely attached and the base is set-up correctly to drill straight and prevent
vibration.
•
Use sufficient pressure to cause the drill bit to cut efficiently, without placing undue stresses on the tool.
If the tool is slowing noticeably, reduce pressure.
•
If the drill bit gets jammed, do not try to release it by switching the tool ON and OFF. Switch the tool OFF
immediately and remove the drill bit using an appropriate spanner. Pull the bit from the hole with caution.
Deep Drilling
When drilling holes that are deeper than the drill bit, follow the steps below:
1. Drill the hole as normal until you have drilled to maximum depth.
2. Break off the core by driving a chisel or slender wedge into the circular kerf. Remove the core using core
tongs, wire or anchor bolts.
3. After removing the core, carefully insert the bit into the hole, attach a bit extension to the bit, then
continue drilling as normal.
