RULES FOR SAFE OPERATION
To help ensure safe operation, please take a moment to learn the machine’s applications and limitations, as well as potential hazards. General® International disclaims any real or implied warranty and holds itself harmless for any injury that
may result from improper use of its equipment.
1. Do not operate the mortiser when tired, distracted, or
under the effects of drugs, alcohol or any medication
that impairs reflexes or alertness.
2. The working area should be well lit, clean and free of
debris.
3. Keep children and visitors at a safe distance when the
mortiser is in operation; do not permit them to operate the mortiser.
4. Childproof and tamper proof your shop and all
machinery with locks, master electrical switches and
switch keys, to prevent unauthorized or unsupervised
use.
5. Stay alert! Give your work your undivided attention.
Even a momentary distraction can lead to serious
injury.
6. Fine particulate dust is a carcinogen that can be haz-
ardous to health. Work in a well-ventilated area and
whenever possible use a dust collector and wear eye,
ear and respiratory protection devices.
7. Do not wear loose clothing, gloves, bracelets, neck-
laces or other jewelry while the mortiser is in operation.
8. Be sure that adjusting wrenches, tools, drinks and
other clutter are removed from the machine and/or
the table surface before operating.
9. Keep hands well away from the mortising chisel, bit
and all moving parts. Use a hold-down or clamp to
secure the stock, and use a brush, not hands, to clear
away chips and dust.
10. Be sure that the mortising chisel and bit are securely
installed in the chuck before operation.
11. Be sure the mortising bit has gained full operating
speed before beginning to drill.
12. Always use a clean, properly sharpened chisel and
bit set. Dirty or dull chisels and bits are unsafe and can
lead to accidents.
13. Use suitable work piece support if the work piece does
not have a flat surface.
14. Do not push or force the chisel and bit into the stock.
The mortiser will perform better and more safely when
working at the rate feed for which it was designed.
15. Avoid working from awkward or off balance positions.
Do not overreach and keep both feet on floor.
16. Never leave the machine unattended while it is run-
ning or with the power on.
17. Use of parts and accessories NOT recommended by
GENERAL® INTERNATIONAL may result in equipment
malfunction or risk of injury.
18. Never stand on machinery. Serious injury could result
if the tool is tipped over or if the mortiser chisel and bit
are unintentionally contacted.
19. Always disconnect the tool from the power source
before servicing or changing accessories such as
chisel and bit sets, or before performing any maintenance, cleaning, or if the machine will be left unattended.
20. Make sure that the switch is in the “OFF”position before
plugging in the power cord.
21. Make sure the tool is properly grounded. If equipped
with a 3-prong plug, it should be used with a threepole receptacle. Never remove the third prong.
22. Do not use this mortiser for other than its intended
use. If used for other purposes, GENERAL® INTERNATIONAL disclaims any real implied warranty and holds
itself harmless for any injury, which may result from
that use.

ELECTRICAL REQUIREMENTS
GROUNDING INSTRUCTIONS
In the event of an electrical malfunction or short circuit,
grounding reduces the risk of electric shock. The motor
of this machine is wired for 110V single phase operation
and is equipped with a 3-conductor cord and a 3prong grounding plug to fit a grounded type receptacle . Do not remove the 3rd prong (grounding pin)
to make it fit into an old 2-hole wall socket or extension
cord. If an adaptor plug is used , it must be attached
to the metal screw of the receptacle.
Note: The use of an adaptor plug is illegal in some
areas. Check your local codes. If you have any doubts
or if the supplied plug does not correspond to your electrical outlet, consult a qualified eletrician before proceeding.
CIRCUIT CAPACITY
Make sure that the wires in your circuit are capable of
handling the amperage draw from your machine, as
well as any other machines that could be operating on
the same circuit. If you are unsure, consult a qualified
electrician. If the circuit breaker trips or the fuse blows
regularly, your machine may be operating on a circuit
that is close to its amperage draw capacity. However, if
an unusual amperage draw does not exist and a
power failure still occurs, contact a qualified technician
or our service department.
BEFORE CONNECTING THE MACHINE TO THE POWER SOURCE,VERIFY THAT THE VOLTAGE OF YOUR POWER SUPPLY CORRESPONDS
WITH THE VOLTAGE SPECIFIED ON THE MOTOR I.D. NAMEPLATE. A POWER SOURCE WITH GREATER VOLTAGE THAN NEEDED CAN
RESULT IN SERIOUS INJURY TO THE USER AS WELL AS DAMAGE TO THE MACHINE. IF IN DOUBT, CONTACT A QUALIFIED ELECTRICIAN
BEFORE CONNECTING TO THE POWER SOURCE.
THIS TOOL IS FOR INDOOR USE ONLY. DO NOT EXPOSE TO RAIN OR USE IN WET OR DAMP LOCATIONS.
EXTENSION CORDS
If you find it necessary to use an extension cord with your
machine, use only 3-wire extension cords that have 3prong grounding plug and a matching 3-pole receptacle that accepts the tool’s plug. Repair or replace a
damaged extension cord or plug immediately.
Make sure the cord rating is suitable for the amperage
listed on the motor I.D. plate. An undersized cord will
cause a drop in line voltage resulting in loss of power
and overheating. The accompanying chart shows the
correct size extension cord to be used based on cord
length and motor I.D. plate amp rating. If in doubt, use
the next heavier gauge. The smaller the number, the
heavier the gauge.
