STANDARD DIE KIT
The standard die kit included with the PR-8
is collection of versatile dies that lend them-
selves to multiple applications. Changing
dies is as easy as turning a screw.
• Electro-hydraulic operation, portable and easy to operate.
• Different sized arms are available for various applications.
• Arms rotate 360° for use at various angles.
• The output pressure can be adjusted for different repair applications.
• Micro-computer control system - Pressure is monitored automatically and has a double safeguard
function, automatically retracting after the rivet has been compressed.
• Manual Reset - Operation can be stopped by pressing the manual reset button. The forward
motion of the ram will stop and will automatically retract to the original position.

3.0 BEFORE USING THIS DEVICE
PR-5 die kits are fully compatible with the PR-8
• The Rivet Gun will beep three times and ash the LED three times when the battery reaches a low voltage
threshold.Lowvoltageconditionisapproximately16.7Volts.
• Eachbatterycanchargeanddischargeforapproximately600cycles.After600cycles,thebatterywill
need to be replaced. When you notice the life of each battery charged gets shorter, this is a good
indication that the battery needs replacement. Do not discharge the battery completely, it will
damage the battery.
• If the rivet gun will not be used for a long period of time, the battery should be removed. Every couple
of months, the batteries should be fully charged without interruption. If the rivet gun will not be used
forextendedperiodsoftime,thebatteriesshouldbechargedto80%atthetimeofstorage.
• Donotburnabatteryinanysituation,possibleexplosionandpersonalinjurymayoccur.
• ThePR-8CordlessRivetSystemandallofitscomponentsshouldneverbeexposedtorainorextremely
humidenvironments.Exposinganypartoftheelectricalsystemwillincreasetheriskofelectricalshock.
• Do not disassemble the rivet gun, the batteries or the charger. If any issues occur during usage, you
should contact your distributor or Pro Spot Headquarters for authorized repairs.
• Check if there are any visible breaks, missing components, adjustment issues or any other issues which
will cause a safety problem or prevent operation. Any issues found must be resolved before the riveter
is to be used.
• The stop screws in the arm are used to prevent the arm from being removed during operation. Verify
that the stop screws are tight before use. The stop screws should only be removed when changing to a
different sized arm.
• The rivet gun should be free of grease and dirt, especially on the handle and trigger to prevent it from
slipping out of your hand during use.
• When changing Dies, remove battery to prevent pinching.
Before using the PR-8 Cordless Rivet System, perform a visual check of the charger, the batteries and the entire
rivet gun along with the arms, punches and dies. This visual inspection should be done before each use. Verify that
the connection for the battery is good. Check all components carefully in order to guarantee safety.

This places the mating point for the die contact
at the Center Line of the arm gap. The lowest

3.Proceedtonextrivet.
Removal Die - The new removal die provides more robust removal of longer rivets (10mm), eliminating jamming and
breaking where the previous SPR rivet was located. Using this system, SPR rivets can be removed in a fraction of
the time it would take to drill out.
Flow Form Rivets -TInareaswhereyoucannottanadjacentSPRorwhererepairproceduresdon’tallowit,Flow
Form Rivets are the answer. Becoming more popular in repair procedures, Flow Form uses a calibration punch,
which allows a Flow Form Rivet to be installed in the same location as the original joint. The time it would take to
