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 hazardous 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, necklaces 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 running 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
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 3- prong 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.
