Safety Instructions for Machinery

G0645 Benchtop Mortising Machine -7-

-8- G0645 Benchtop Mortising Machine
No list of safety guidelines can be complete.
Every shop environment is different. Always
consider safety first, as it applies to your
individual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious per-
sonal injury, damage to equipment, or poor
work results.
Like all machinery there is potential danger
when operating this machine. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this machine
with respect and caution to lessen the pos-
sibility of operator injury. If normal safety
precautions are overlooked or ignored, seri-
ous personal injury may occur.
Additional Safety for Mortising Machines
5. ADJUSTMENTS. Hands may be seriously
injured if they come in contact with the
chisel and drill bit during operation. Do not
adjust the machine or workpiece while the
mortising machine is running. Wait for the
spindle to come to a complete stop and
unplug the machine before continuing.
6. INSPECTING MACHINE. Loose chisels
and bits can be ejected at the operator,
or the headstock can fall if not properly
secured, causing serious personal injury.
Inspect the machine for smooth head cast-
ing movement, loose drill bits/chisel hous-
ing, loose nuts/bolts and lock levers before
connecting the machine to power and oper-
ating. Correct any problems before use.
7. EXPERIENCING DIFFICULTIES. If at any
time you are experiencing difficulties per-
forming the intended operation, stop using
the machine! Contact Tech Support at
(570) 546-9663.
1. HAND PROTECTION. Do not place your
hands under an installed chisel at any
time or near the chisel while the spindle
is in motion. Chisels may become hot dur-
ing operation! Allow chisels to cool before
handling. Chisels are sharp! Always use
caution when handling, especially when
installing or removing.
2. USING CORRECT MATERIALS. Mortising
materials such as metals, plastics, and
glass can result in serious personal injury
and machine damage. Do not use the
machine for anything except mortising in
wood.
3. RESPIRATOR AND SAFETY GLASSES.
Dust and chips created from mortising and
may be ejected, becoming hazards to the
eyes and lungs. Always wear a respira-
tor and safety glasses while operating the
machine.
4. CHISEL COMPATIBILITY. Mortising bits
can fly out of chuck at the operator if not
properly secured, causing serious personal
injury. Make sure the mortising bit fits a
minimum of 1/2" into the chuck.

Workbench Load
Refer to the Machine Data Sheet for the weight
and footprint specifications of your machine.
Some workbenches may require additional rein-
forcement to support both the machine and the
workpiece.
Placement Location
Consider existing and anticipated needs, size of
material to be processed through each machine,
and space for auxiliary stands, work tables or
other machinery when establishing a location for
your new machine. See Figure 5 for the minimum
working clearances. The workbench should be
located where plenty of working clearance exists
for larger workpieces.
Children and visitors may be
seriously injured if unsuper-
vised around this machine.
Lock entrances to the shop
or disable start switch or
power connection to prevent
unsupervised use.
The unpainted surfaces are coated with a waxy
oil to prevent corrosion during shipment. Remove
this protective coating with a solvent cleaner or
citrus-based degreaser such as Grizzly’s G7895
Citrus Degreaser. To clean thoroughly, some parts
must be removed. For optimum performance
from your machine, clean all moving parts or
sliding contact surfaces. Avoid chlorine-based
solvents, such as acetone or brake parts cleaner
that may damage painted surfaces. Always follow
the manufacturer’s instructions when using any
type of cleaning product.
Site ConsiderationsClean Up
Figure 5. Minimum working clearances.
Gasoline and petroleum
products have low flash
points and can explode
or cause fire if used to
clean machinery. DO
NOT use these products
to clean the machinery.
Many cleaning solvents
are toxic if inhaled.
Minimize your risk by only
using these products in a
well ventilated area.
Figure 4. Grizzly citrus degreaser.
G7895—Grizzly Citrus Degreaser
This natural, citrus-based degreaser is a great
solution for removing export grease, and it’s much
safer to work around than nasty solvents.

-14- G0645 Benchtop Mortising Machine
AssemblyMounting
Mount the mortising machine to a workbench
through the two holes in the base.
The strongest mounting option is a "Through
Mount" where holes are drilled all the way through
the workbench, and hex bolts, washers, and hex
nuts are used to secure the mortising machine to
the workbench.
Figure 6. Example of a through mount setup.
Figure 7. Example of a direct mount setup.
Another option for mounting is a "Direct Mount"
where the machine is simply secured to the work-
bench with a lag screw. Figure 8. Hand lever installed.

The included extension block will extend the col-
umn an additional 13⁄4", so workpieces up to 6"
thick can be mortised. You will not be able to use
the fence adjustment knob when the extension
block is installed. If you do not want to install the
extension block, skip Steps 6-8.
To assemble the Model G0645:
1. Secure the handle onto the hub using the
spring and shoulder bolt already attached to
the headstock, as shown in Figure 8.
2. Loosen the lock lever and insert the depth
stop rod into the hole on the headstock, as
