Laser Guide
The laser should be checked and adjusted before starting a new project, and any time you raise or lower the table, or change workpiece thickness.
DO NOT look directly into laser. Severe eye injury will result.
To adjust laser:
1. DISCONNECT DRILL PRESS FROM
POWER!
7. Adjust laser (Figure 2), positioning it by hand so crosshairs align with indentation you made earlier in surface of workpiece, as shown in
Figure 3.
2. Install drill bit in chuck (see Installing/ Removing Drill Bits on Page 25 of Model
G7944 manual).
3. Clamp workpiece securely to table.
4. Adjust table so workpiece is within range of
drill bit, then lock table in horizontal position.
5. Lower drill bit so it touches workpiece, mak­ing a slight indentation in the surface, then raise bit.
6. Connect drill press to power. Turn laser ON using switch on front of drill press (see
Figure 1).

Digital Readout
The model G0794 is equipped with a digital read­out (DRO) for precision spindle adjustment. The DRO is independently powered by a SR44 but­ton cell battery, which may need to be changed from time to time. Follow the instructions below to change the battery.
Tools Needed: Qty
Phillips Head Screwdriver #2 ............................ 1
3. Remove (4) M4 x 12 tap screws shown in Figure 5, and remove DRO unit from hous-
ing.
To change DRO battery:
1. DISCONNECT DRILL PRESS FROM
POWER!
2. Remove (1) shoulder screw, then remove (4) M5-.8 x 14 Phillips head screws shown in Figure 4 and remove DRO housing.

WIRING
These pages are current at the time of printing. However, in the spirit of improvement, we may make chang­es to the electrical systems of future machines. Compare the manufacture date of your machine to the one
number and manufacture date of your
machine before calling. This information can be found on the main machine label.
stated in this manual, and study this section carefully.
If there are differences between your machine and what is shown in this section, call Technical Support at (570) 546-9663 for assistance BEFORE making any changes to the wiring on your machine. An updated wiring diagram may be available. Note: Please gather the serial
Wiring Safety Instructions
SHOCK HAZARD. Working on wiring that is con-
nected to a power source is extremely dangerous. Touching electrified parts will result in personal injury including but not limited to severe burns, electrocution, or death. Disconnect the power from the machine before servicing electrical com­ponents!
MODIFICATIONS. Modifying the wiring beyond what is shown in the diagram may lead to unpre­dictable results, including serious injury or fire. This includes the installation of unapproved after­market parts.
WIRE CONNECTIONS. All connections must be tight to prevent wires from loosening during machine operation. Double-check all wires dis­connected or connected during any wiring task to ensure tight connections.
CIRCUIT REQUIREMENTS. You MUST follow the requirements at the beginning of this manual when connecting your machine to a power source.
WIRE/COMPONENT DAMAGE. Damaged wires or components increase the risk of serious per­sonal injury, fire, or machine damage. If you notice that any wires or components are damaged while performing a wiring task, replace those wires or components.
MOTOR WIRING. The motor wiring shown in these diagrams is current at the time of printing but may not match your machine. If you find this to be the case, use the wiring diagram inside the motor junction box.
CAPACITORS/INVERTERS. Some capacitors and power inverters store an electrical charge for up to 10 minutes after being disconnected from the power source. To reduce the risk of being shocked, wait at least this long before working on capacitors.
EXPERIENCING DIFFICULTIES. If you are expe­riencing difficulties understanding the information included in this section, contact our Technical Support at (570) 546-9663.

This manual provides critical safety instructions on the proper setup, operation, maintenance, and service of this machine/tool. Save this document, refer to it often, and use it to instruct other operators.
Failure to read, understand and follow the instructions in this manual may result in fire or serious personal injury—including amputation, electrocution, or death.
The owner of this machine/tool is solely responsible for its safe use. This responsibility includes but is not limited to proper installation in a safe environment, personnel training and usage authorization, proper inspection and maintenance, manual availability and compre­hension, application of safety devices, cutting/sanding/grinding tool integrity, and the usage of personal protective equipment.
The manufacturer will not be held liable for injury or property damage from negligence, improper training, machine modifications or misuse.
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
Lead from lead-based paints.
Crystalline silica from bricks, cement and other masonry products.
Arsenic 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.
