Hougen HMD908, Operator'S Manual

Page: 6 / 23

OPERATING INSTRUCTIONS
Always remember that the magnet’s holding power is directly related to the workpiece thickness and surface
condition. (Rating of 748 Kg pull is based on test using a 25mm thick ground surface.) Since magnetic
attraction diminishes with thinner material or rough surfaces, mechanical clamping of drill unit to the workpiece should be
used when cutting thin material (9.5mm or less) or material with uneven surfaces.
1. Make sure workpiece and bottom of magnet are free of chips, oil, etc.
2. Position drill by sliding it and gently feeding Arbor so that pilot point is touching center of hole to be drilled.
3.
Secure unit to workpiece with safety chain.
4. Turn magnet ON by pressing the magnet ON switch.
5. Turn Feed Handle, raising the cutter until the pilot is above the work surface.
6. Make certain that cutter is clear of workpiece and turn motor ON by pressing the motor START switch.
7. Feed Hougen Cutter slowly into workpiece. Only after cutting path is established to a depth of about 2mm
can full force be applied to feed handles.
8. Ease up on feed pressure Ease up on feed pressure as cutter starts breaking through.
9. At conclusion of cut, turn motor OFF by pressing motor STOP switch. Turn Feed Handles to raise Arbor
thereby ejecting the slug if it hasn’t already fallen free.
10. Turn magnet OFF by pressing the magnet OFF switch.
11.
Disconnect from power source.
12. If necessary, remove chips from cutter and magnet, preferably wearing leather work gloves and/or with pliers.
Disconnect safety chain and you are ready to move unit to new drilling position.

OPERATION OF CONTROLS
BEFORE INSTALLING HOUGEN CUTTER
IMPORTANT: Before turning on the machine, it is important that
the operator understands the interrelated functions of the SAFETY
SWITCH, MAGNET SWITCH, AND MOTOR SWITCHES.
READ SAFETY SWITCH INDICATOR LIGHT INSTRUCTIONS
ON PREVIOUS PAGE.
SAFETY SWITCH — Located in base of drill. Enables motor
operation only when magnet is properly seated on a clean
and fl at work surface. Turns motor off if switch detects lift of
unit.
MAGNET ON/OFF SWITCH — Energizes and De-energizes
the magnetic base and activates the safety switch. Motor can
now be started by pushing the motor START switch.
MOTOR START/STOP SWITCHES — Starts and stops the
motor (See instructions previous page).
CIRCUIT BREAKER - The circuit breaker is designed to “trip”
when the motor is over loaded. To reset the circuit breaker,
turn off the magnet, unplug the machine and allow to cool
down for approx. 5 minutes. Restart the machine by depress-
ing the circuit breaker, plugging the machine in and continue
your normal operations.
CONTROL PANEL SWITCH PLATE
FIGURE 2
1. Place Magnetic Drill on clean, fl at steel plate that is at least 9.5mm thick.
2. Plug unit into proper AC power source. DO NOT use with DC Power.
3. Locate the Magnet ON and OFF switch and the motor STOP and START switches (Fig. 2).
4. NOTE: A loss of power will de-energize the magnetic base and deactivate the motor. When power is
restored, the magnet will reenergize, however, the motor START switch must be depressed before
the motor will start.
