Operator’s manual for drilling machine

Prior to use always make sure that the machine is secured from dropping
with original chain (as described in paragraph I no. 5
“Important rules of safe
use of drilling machine
”).
2.3 Cutting
- Select the right speed for the tool you intend to use (see the speeds chart in this
manual
– paragraph IV no.1).
Cooling and lubricant fluid commercially available in concentrated form are recommended for
cooling twist drills and annular cutters.
The use of emulsions formed from a mixture of water and drilling oil are acceptable.
Do not use clean water as the liquid cooling and lubricant.
The cooling system is an integral part of the machine and should always be used. (see point
2.7)
Warning: The cooling system can only be used when drilling machine is in
vertical position. In other positions an additional external source of cooling should be
used, for example: a coolant bottle with a long nozzle or a pressurized system.
- Check the operation of the
cooling system. Open coolant reservoir’s tap and apply
pressure on the pilot by turning spokes counter clockwise. As the pilot starts to sink into the
cutter cooling liquid should start to run down cutters inner wall. If there is no liquid flowing
down check if the tap is fully opened. It may take a few seconds for cooling liquid to fill the
whole system.

Turn the motor on.
Making a hole with a milling cutter should ideally be done in one pass. The proper
method is to put the motor under load in which it experiences about a 10% reduction in
speed by listening to the sound it emits. It makes the cutter work better and more easily
ejects the slug after the hole is completed. If you experience slugs getting stuck inside a
cutter after the hole is complete try to reduce pressure on the cutter or use a different
coolant. Do not allow excessive swarf build up around the cutter and arbor.
WARNING: when the milling cutter goes through the material the
slug can be pushed out often with considerable strength.
Pay attention to avoid injury.
When drilling holes deeper than 50 mm (2’’), retract the tool above the workpiece as
often as possible to allow the chips to be expelled from the hole. Additionally, once the tool is
retracted, clean the grooves of the tool using a small brush if they are clogged. After
exceeding 40 mm of the drilling depth, introduce the cutting fluid into the milling area
manually (from the bottle).
