We are proud to offer the Grizzly Model
H3142 Pneumatic Palm Hammer Kit. The
Model H3142 is part of a growing Grizzly
family of fine power tools. When used
according to the guidelines set forth in this
manual, you can expect years of troublefree, enjoyable operation and proof of
Grizzly’s commitment to customer satisfaction.
The Model H3142
Pneumatic Palm
Hammer Kit
will allow you to drive common
nails in tight spots and have the power of a
hammer in the palm of your hand. Includes
chisel, steel-faced hammer head, soft-faced
hammer head, leather hand strap bag, 2 finish nail drivers, 2 regular nail drivers and a
durable plastic carrying case.
Read the manual before operating the
palm hammer. Become familiar with
this tool, its safety instructions, and
its operation before beginning any
work. Serious personal injury may
result if safety or operational information is not understood or followed.
H3142 Pneumatic Palm Hammer Kit -5-
Connecting to Air System Basic Operation
Exceeding the maximum permissible
operating pressure may cause the
palm hammer to explode, blowing
metal fragments in all directions. To
protect yourself from serious personal injury, DO NOT allow your air compressor to exceed the recommended
pressure when connected to this tool!
The Model H3142 is designed to be operated at 80-120 psi. DO NOT exceed the
maximum operating pressure!
To connect the Model H3142 to an air
compressor:
1. Regulate the air pressure on the air
compressor to barely over the minimum
80 PSI required to operate the palm
hammer. Increase air pressure only if
needed.
2. Attach your air compressor hose to the
coupling on the palm hammer.
NOTE: Many pneumatic tools benefit from
an in-line filter/lubricator/regulator unit.
This attachment is connected by hoses
between the air compressor and the palm
hammer. Using this unit protects your tool
from damaging water build-up, allows you
to adjust and maintain constant air pressure to your tool, and saves you the inconvenience of having to manually lubricate
your tool every time you use it. Check the
current Grizzly catalog for availability of
this unit. If you plan on installing a
filter/lubricator/regulator unit in your compressed air system, always follow the connection instructions that come with the unit.
OPERATION
The Model H3142 does not have an actuation trigger; instead, this unit actuates
when one of the installed tools is
depressed against the workpiece. There is
no safety mechanism so disconnect the
palm hammer when not in use or when
changing tools!
Specific operating instructions for each tool
will be described later in this manual.
Changing Tools
To change tools:
1. Disconnect the palm hammer from
the air compressor.
2. Unscrew the current attachment from
the face of the palm hammer.
3. Make sure there is a spring inside the
threaded portion of the tool before
installing. The longest and narrowest
spring is for the chisel tool only.
4. Screw the desired tool into the face of
the palm hammer.
Serious personal injury could occur if
palm hammer is connected to air
compressor when changing tools.

Hand Strap Bag
The Model H3142 Pneumatic Palm
Hammer Kit includes a hand strap bag to
ease carrying and operation. Figure 1
shows the hand strap bag attached to the
palm hammer.
Figure 1. Hand strap bag on palm hammer.
To use the hand strap bag:
1. Install the hand strap bag on the palm
hammer and make sure each snap button is secure.
2. Place your fingers through the large
strap and place your thumb through one
of the small straps on the side, depending on which hand you prefer to use.
The nail drivers attach to the palm hammer
with the driver adapter shown in Figure 4.
To use a nail driver:
1. With the air NOT connected to the palm
hammer, install the desired nail driver
tool as per the “Changing Tools”
instructions on page 5 of this manual,
then connect the palm hammer to the
air compressor.
2. Position the nail where you want to
drive it.
3. Place the nail driver over the nail and
start the nail with a light bump or tap of
the palm hammer. This action should
only make the hammer actuate once.
4. Making sure the nail is started deep
enough to keep its position, firmly press
the palm hammer into the nail and hold
it until the nail is completely driven into
the surface.

Figure 6. Soft-faced hammer head.
Chisel Tool
The Model H3142 Pneumatic Palm
Hammer Kit includes a chisel tool as
shown in Figure 7.
Figure 7. Chisel tool.
To use the hammer head tools:
1. With the air NOT connected to the palm
hammer, install the desired hammer
head tool as per the “Changing Tools”
instructions on page 5 of this manual,
then connect the palm hammer to the
air compressor.
2. Tap the hammer head against the
object for a single blow.
3. Press and hold the hammer head
against the object for multiple blows.
To use the chisel tool:
1. With the air NOT connected to the palm
hammer, install the chisel tool as per
the “Changing Tools” instructions on
page 5 of this manual.
2. Before tightening, rotate chisel so blade
is parallel to your work surface while the
palm hammer is held at the intended
angle of operation.
3. Tighten the jam nut on the chisel
threads into the base of the palm hammer to keep the chisel secured in its
determined position.
4. Connect the palm hammer to the air
compressor.
5. Press the chisel against the workpiece
to make it actuate.
H3142 Pneumatic Palm Hammer Kit-8-
Cleaning Palm Hammer
Do not allow dust, chips, sand, etc. into the
air connectors or into the body of the palm
hammer; this may result in leaks and damage to the palm hammer and the air fittings.
Use a good solvent to clean the palm hammer tools. Always be sure that the tools
are dry before using them again.
Always disconnect air from palm air
hammer whenever cleaning! If connected to air, hammer may actuate
accidentally, causing serious personal injury!
Oiling Palm Hammer
Regular applications of oil will extend the
useful life of the piston assembly.
Special oil has been included with your
new Grizzly Palm Hammer. Before each
use, and regularly during prolonged applications, place one drop of oil in the palm
hammer air inlet as illustrated in Figure 6.
After oiling, wipe off any excess oil near
the exhaust to avoid dust build-up. When
the oil that was included with the palm
hammer has been completely used,
replace it with Grizzly Model G2820
Pneumatic Tool Oil.
Another option to manual oiling would be
to install a lubricator in your air compressor
line. If your air compressor line already has
a lubricator, then regular lubrication of your
palm hammer will not be necessary. Just
make sure there is always oil in the lubricator.
As mentioned before, the best option is to
install a filter/lubricator/regulator unit such
as the Grizzly Model H2333 in your air line.
Figure 6. Lubricating palm hammer
via air inlet.
NOTICE
Too much oil in the hammer will ruin
the O-rings!
