Pneumatic Pulse Tool Line

Pneumatic Pulse Tool Line from Sumake North America

We hope you enjoy this video overview of our pneumatic pulse tool line. These tools come in
an inline version, a pistol version, and an angle head version. The tools also come in a slip
clutch, as well as an auto-stop clutch version. The torque range on these tools goes from 4 foot-
pounds to about 200 foot-pounds. They are very light and the counter force on these tools is
very low, so they don’t twist the operator’s hand when they are in use.

Choosing a Pneumatic Pulse Tool

When choosing one of these tools, your application torque range should be in the middle of the
tool’s torque range. So if you’re looking for 45 foot-pounds, make sure that the 45 foot-pounds is
the middle of the range of the tool. This is important because the tool is filled with hydraulic fluid
that will wear out much quicker if you’re at the higher end of the torque. The hydraulic fluid
needs to be changed once a year (on average). You can send it to Sumake North America to
have the fluid changed.

Adjusting the Torque

The torque on these pneumatic pulse tools is very easily adjusted using the provided hand
tools in the box. It’s also protected from any operator being able to alter the torque while on the
operating line. You simply remove the set screw at the tip of the driver, place that aside, and
grab your screwdriver, clockwise is to increase torque, and counterclockwise is to decrease
torque. After your torque is set to the desired torque, replace the screw, and you are good to
operate. Note: Make sure the tool is not plugged into air during adjustment.

Pneumatic Pulse Tool Operation

Before we go over the operation of this tool, here are a couple more points about the
maintenance program. Daily, there should be some pneumatic tool oil dropped directly into the
inlet of the tool to help lubricate all of the internal moving parts. It is very important that these
tools are sent roughly once a year to have their oil changed. If you are using the tool at the top
end of the torque range, then closer to the 6-month or 8-month range. If you’re using it towards
the bottom, you will get the full year out of the tool and again this has to do with the hydraulic oil
breakdown inside the tool. If the tool is used too long after the oil is broken down, it will actually
begin to lose torque output and you won’t see consistent torque output from your tool.

Pneumatic Pulse Tools in Action

When hooking up these tools, they use a standard quarter-inch air hose. They should be run at
90 PSI. These tools are very quiet when compared to impact tools. You’ll notice with this slip
clutch tool, as the trigger is held down, it is going to continue to impulse the bolt we have here. If
this was a shut-off screw, it would actually shut off after two or three of these impulses. With a
shut-off screw, as soon as the tool comes up to torque, the driver will shut off and the operator
is ready to move on to the next bolt. If you want more information on these pneumatic pulse
