SAFETY INSTRUCTIONS

1. Always wear 

eye protection

when operating the tool.

2. To avoid injury 

do not point the tool at anyone.

3.

Do not exceed recommended maximum air pressure

(100 psi max.).

4.

Disconnect the tool from the air supply

when not in use for an extended period of time 

or before proceeding with any maintenance procedures. Take care to control air hoses when dis-
connecting to prevent whipping.

5.

Do not attempt to operate the tool with the Nose Housing removed.

This exposes potential

pinch points and could result in injury.

6.

Do not tamper with the Clamp Screws or Fill Screw.

Loosened screws may result in 

malfunction or injury due to air or hydraulic pressure.

7.

Do not operate the tool without either the deflector (PRT Option) or the collector (MCS
Option) installed on the tool.

Spent rivet mandrels may be forcefully ejected.

8.

Always clear the tool of spent rivet mandrels

before setting a new fastener. Failure to do so may

result in tool jams or forceful ejection of spent mandrels.

9.

Use caution when holding the tool at an angle

since compressed air is released through 

the Intensifier Chamber and may be directed toward the operator. Do not direct exhaust towards
anyone.

10. Inspect the tool at regular intervals for damage and proper function.

Replace damaged parts

immediately. Do not connect a damaged tool to an air supply.

11.

Use only genuine Pop

®

brand replacement parts.
