Safety Instructions for Machinery
17. REMOVE ADJUSTING KEYS AND
WRENCHES. Make a habit of checking for
keys and adjusting wrenches before turn
-
ing machinery
ON.
18. CHECK FOR DAMAGED PARTS
BEFORE USING MACHINERY. Check
for binding and alignment of parts, broken
parts, part mounting, loose bolts, and any
other conditions that may affect machine
operation. Repair or replace damaged
parts.
19. USE RECOMMENDED ACCESSORIES.
Refer to the instruction manual for recom
-
mended accessories. The use of improper
accessories may cause risk of injury.
20. DO NOT FORCE MACHINERY. Work at
the speed for which the machine or acces
-
sory was designed.
21. SECURE WORKPIECE. Use clamps or
a vise to hold the workpiece when practi-
cal. A secured workpiece protects your
hands and frees both hands to operate the
machine.
22. DO NOT OVERREACH. Keep proper foot
-
ing and balance at all times.
23. MANY MACHINES WILL EJECT
WORKPIECE TOWARD OPERATOR.
Know and avoid conditions that cause the
workpiece to "kickback."
24. ALWAYS LOCK MOBILE BASES
(IF USED) BEFORE OPERATING
MACHINERY.
25. BE AWARE THAT CERTAIN WOODS
MAY CAUSE AN ALLERGIC REACTION
in people and animals, especially when
exposed to fine dust. Make sure you
know what type of wood dust you will be
exposed to and always wear an approved
respirator.
G7945/G7946 Radial Drill Press

1. EYE/FACE/HAND PROTECTION. A face
shield used with safety glasses is rec
-
ommended. Always keep hands and fin
-
gers away from the drill bit. Never hold a
workpiece by hand while drilling! DO NOT
wear gloves when operating
the drill.
2. SECURING BIT. Properly tighten and
securely lock the drill bit in the chuck.
3. CORRECT BIT.
Use only round, hex, or
triangular shank drill bits.
4. ADJUSTING KEYS AND WRENCHES.
Remove all adjusting keys and wrenches
before turning the machine ON
.
5. DRILLING SHEET METAL. Never drill
sheet metal unless it is securely clamped to
the table.
6. SURFACE /WORKPIECE PREPARATION.
Never turn the drill press ON before clearing
the table of all objects (tools, scrap wood,
etc.) DO NOT drill material that does not
have a flat surface, unless a suitable sup
-
port is used.
7. DAMAGED TOOLS. Never use tools in poor
condition. Dull or damaged cutting tools
are hard to control and may cause serious
injury.
Additional Safety for Drill Presses
8. DRILL OPERATION. Never start the drill
press with the drill bit pressed against the
workpiece. Feed the drill bit evenly into the
workpiece. Regularly back the bit out of
deep holes to clear chips.
9. OPERATING SPEED.
Always operate your
drill press at speeds that are appropriate
for the drill bit size and the material that you
are drilling
.
10. MAINTENANCE/SPEED CHANGES.
Never do maintenance or change speeds
with
the machine plugged in.
11. MOUNTING WORKPIECES. Use clamps
or vises to secure workpiece before drill
-
ing. Position work so you avoid drilling into
the table.
12. TABLE LOCK. Make sure the table lock is
tightened before starting the drill press.
13. EXPERIENCING DIFFICULTIES.
If at
any time you are experiencing difficulties
performing the intended operation, stop
using the machine! Contact our Service
Department at (570) 546-9663.

G7945/G7946 Radial Drill Press
The unpainted surfaces are coated with a waxy
oil to protect them from corrosion during ship
-
ment. Remove this protective coating with a sol
-
vent cleaner or citrus-based degreaser such as
Grizzly’s G7895 Degreaser. To clean thoroughly,
some parts may need to be removed. For opti
-
mum performance from your machine, make
sure you clean all moving parts or sliding
contact surfaces that are coated. Avoid chlo
-
rine-based solvents, such as acetone or brake
parts cleaner, as they may damage painted sur
-
faces should they come in contact. Always follow
the manufacturer’s instructions when using any
type of cleaning product.
Clean Up
Gasoline and petroleum
products have low flash
points and could cause
an explosion or fire if
used to clean machinery.
DO NOT use gasoline or
petroleum products to
clean the machinery.
Many of the solvents
commonly used to clean
machinery can be toxic
when inhaled or ingest
-
ed. Lack of ventilation
while using these sol
-
vents could cause seri
-
ous personal health risks
or fire. Take precautions
from this hazard by only
using cleaning solvents
in a well ventilated area.
Floor Load
Refer to the Machine Data Sheet for weight and
footprint specifications for your machine. Some
residential floors may require additional reinforce
-
ment to support both the machine and operator.
Some workbenches may require additional rein
-
forcement to support both the machine and the
workpiece.
Working Clearances
Consider existing and anticipated needs, size of
material to be processed through each machine,
space for auxiliary stands, work tables or other
machinery, and the great range of movement
in the Model G7946/G7946 when establishing
a location for your machine. See Figure 6 for
the minimum working clearances of the Model
G7945/G7946.
Unsupervised children and
visitors inside your shop
could cause serious per
-
sonal injury to themselves.
Lock all entrances to the
shop when you are away and
DO NOT allow unsupervised
children or visitors in your
shop at any time!

the beveled edge of the column ring over the
rack, and tighten the set screw.
Note: Do not
over-tighten the set screw or you may split the
column ring. Also make sure the rack is seated
firmly in the lower ring.
8. Thread a clamp bolt into the non-threaded
side on the back of the table bracket
about
three turns, for now.
