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.

Laser Guide 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.

DO NOT look directly into laser. Severe eye

injury will result.

To adjust laser:

1. DISCONNECT DRILL PRESS FROM

POWER!

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, mak-

ing 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).

5. Replace battery with new SR44 button cell

battery and re-install battery cover.

6. Re-install DRO unit and DRO housing, mak-

ing sure to re-install shoulder screw from

Step 2.

The model G0794 is equipped with a digital read-

out (DRO) for precision spindle adjustment. The

DRO is independently powered by a SR44 but-

ton 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

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

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 com-

ponents!

MODIFICATIONS. Modifying the wiring beyond

what is shown in the diagram may lead to unpre-

dictable results, including serious injury or fire.

This includes the installation of unapproved after-

market parts.

WIRE CONNECTIONS. All connections must

be tight to prevent wires from loosening during

machine operation. Double-check all wires dis-

connected 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 per-

sonal 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 expe-

riencing difficulties understanding the information

included in this section, contact our Technical

Support at (570) 546-9663.

Wiring Safety Instructions

The photos and diagrams

included in this section are

best viewed in color. You

can view these pages in

color at www.grizzly.com.

These pages are current at the time of printing. However, in the spirit of improvement, we may make chang-

es to the electrical systems of future machines. Compare the manufacture date of your machine to the one

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

number and manufacture date of your

machine before calling. This information can be found on the main machine label.

OWNER'S MANUAL

(For models manufactured since 09/17)

V3.05.18

G7943 G7944

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 compre-

hension, 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 equip-

ment, such as those dust masks that are specially designed to filter

out microscopic particles.
