Operators Manual for Drilling Machine
CAUTION: READ THE WHOLE INSTRUCTIONS MANUAL
BEFORE ATTEMPTING TO START UP
5.3 Before you cut
Before positioning the machine on the work piece, always make sure that:
-
work piece is made of steel;
-
thickness of work piece is at least 3/8” (10 mm)
-
surface of steel under the magnet is flat
-
wipe, brush or sand down clean surface where you intended to place the
drilling machine, so that you remove rust, paint, dirt etc which would reduce adhesive
power of the electromagnetic base.
Install drill bit, annular cutter or other tooling such as tap or reamer in the machine
before plugging it in. Then plug it in (see paragraph 3) and position where you wish
to use it. Place the machine so that the tool is over the center of the hole you intend
to make and turn the magnetic base ON.
Prior to use always make sure that the machine is secured from falling
down with original chain (as described in paragraph 4 “Important rules of safe
use of drilling machine”).
5.4 Cutting
-
Cooling and lubricant fluid commercially available in concentrated form are
recommended for cooling twist drill bits and annular cutters.
It’s allowed to use emulsions formed from a mixture of water and drilling oil.
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 5.7)
Warning: The cooling system can only be used when drilling machine is
in vertical position. In other positions additional external source of cooling
should be used, for example: a coolant bottle with a long nozzle, or a paste
type lubricant.
-
Check to make sure the cooling system is working. Open coolant reservoir’s
valve 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 to make sure valve is fully opened. It
may take a few seconds for cooling liquid to fill the whole system.
-
Turn the motor on.
