GENERAL SAFETY RULES
Woodworking can be dangerous if safe and proper operating procedures are not followed. As with all
machinery, there are certain hazards involved with the operation of the product. Using the machine with
respect and caution will considerably lessen the possibility of personal injury. However, if normal safety
precautions are overlooked or ignored, personal injury to the operator may result. Safety equipment such
as guards, push sticks, hold-downs, featherboards, goggles, dust masks and hearing protection can
reduce your potential for injury. But even the best guard will not make up for poor judgment, carelessness
or inattention. Always use common sense and exercise caution in the workshop. If a procedure feels
dangerous, do not try it. Figure out an alternative procedure that feels safer. REMEMBER: Your personal
safety is your responsibility.
This machine was designed for certain applications only. We strongly recommend that this machine
cannot be modified and/or used for any application other than that for which it was designed. If you have
any questions relative to a particular application, DO NOT use the machine until you have first contacted
your local dealer to determine if it can or should be performed on the product.

Always operate machinery in well ventilated areas and provide for proper dust removal. Use wood
dust collection systems whenever possible.
25. WARNING: SOME DUST CREATED BY POWER SANDING, SAWING, GRINDING, DRILLING,
AND OTHER CONSTRUCTION ACTIVITIES contains chemicals known to cause cancer, birth
defects or other reproductive harm. Some examples of these chemicals are:
zlead from lead-based paints,
zcrystalline silica from bricks and cement and other masonry products, and
zarsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed to filter out microscopic particles.

WARNING: FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS PERSONAL INJURY.
SAVE THESE INSTRUCTIONS.
Refer to them often
and use them to instruct others.
CONNECTING TOOL TO POWER SOURCE
POWER CONNECTIONS
A separate electrical circuit should be used for your tools. If an extension cord is used, use only 3-wire
extension cords, which have grounding type plugs and receptacles, which accept the tool’s plug. Before
connecting the motor to the power line, make sure the switch is in the “OFF” position and be sure that the
electric current is of the same characteristics as indicated on the tool.
All line connections should make good contact. Running on low voltage will damage the motor.
WARNING: DO NOT EXPOSE THE TOOL TO RAIN OR OPERATE THE TOOL IN DAMP LOCATIONS.
MOTOR SPECIFICATIONS
Your tool is wired for 230 volt, 50Hz alternating current. Before connecting the tool to the power source, make
sure the machine is cut off from power source.
GROUNDING INSTRUCTIONS
WARNING: THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.
All grounded, cord-connected tools:
In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to
reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding
conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and
grounded in accordance with all local codes and ordinances.
Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified
electrician.
Improper connection of the equipment-grounding conductor can result in risk of electric shock. The conductor
with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding
conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the
equipment-grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the grounding instructions are not completely
understood, or if in doubt as to whether the tool is properly grounded.
Use only 3-wire extension cords that have grounding type plugs and receptacles that accept the tool’s plug.
Repair or replace damaged or worn cord immediately.
WARNING: IN ALL CASES, MAKE CERTAIN THE RECEPTACLE IN QUESTION IS PROPERLY
GROUNDED. IF YOU ARE NOT SURE, HAVE A QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.

５
Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension
cord, which has a grounding type plug and a receptacle, which will accept the tool’s plug. When using an
extension cord, be sure to use one heavy enough to carry the current of the tool. An undersized cord will
cause a drop in line voltage, resulting in loss of power and overheating.
OPERATING INSTRUCTIONS
FOREWORD
Fox Model F14-652 is easier to operate than a conventional drill press equipped with a mortising
attachment. The model F14-652 is made of cast-iron and steel for rigidity and stability. The mortiser
comes with a standard 3-jaw type key chuck for positive gripping of mortising bits.
UNPACKING AND CLEANING
Carefully unpack the machine and all loose items from the shipping carton(s). Remove the protective
coating from all unpainted surfaces. This coating may be removed with a soft cloth moistened with
kerosene (do not use acetone, gasoline or lacquer thinner for this purpose). After cleaning, cover the
unpainted surfaces with a good quality household floor paste wax.

INSTALLING CHISEL & BIT
1. Loosen lock screw, shown in Figure 7.
Fig7 Fig8
2. Insert chisel bushing (with the hole facing forward) into the head. Tighten the screw just
enough to hold the chisel in place.
!
NOTE: Set the slot in the side of the chisel to the left or right, NOT to the front or back. This will allow
chips to escape when cutting mortises.
3. Push the chisel up as far as possible into the head. Then lower the chisel approximately 0.8mm to
1.6mm, depending on the type of wood being worked. Tighten the screw to hold chisel in place.
4. Push bit up through the chisel opening as far as it will go. Lock the drill bit in place with the chuck key.
5. Loosen screw and push chisel up against the bushing, then tighten screw. This should provide
the proper distance between the points of the chisel and the bit.
MAINTENANCE
The Mortiser requires only minor maintenance, such as cleaning and lubrication and routine adjustment
and sharpening of the chisel and bit.
Dust the machine down after each use and, as necessary, use light applications of oil or grease to
lubricate linkages, moving parts, etc.
SHARPENING CHISEL & BIT
The chisel and bit should be kept sharp for best performance. Blunt edges will give inaccurate
mortises and can lead to overheating and breakage to chisel or bit. If chisel and bit are badly worn and
become difficult to sharpen, they should be replaced.
1. Sharpen the bit by using a small, smooth file, following the original shape of the bit. File the inside edge
of the spur, the sides of the brad point, and the cutting edge inwards toward the flute of the bit. See Fig. 8.
Do not file the outside edge of the spur as this will affect the diameter of the bit.
2. Sharpen the chisel with a mortise chisel cutter with the correct size pilot. (Pilot size will differ
depending on the size of your chisel). Two or three turns of the cutter in a carpenter's brace chuck should
be enough to sharpen the chisel, as shown in Fig. 9.

3. Use a small, triangular, smooth file to relieve the inner corners of the chisel. See Fig.10.
Remove any burrs from the outside of the chisel with a fine oilstone.
