TROUBLE SHOOTING

Tool installs rivet-nut

but will not reverse.

Usually because the tool is low

on oil and the pull piston is not

stroking far enough to engage the

reversing valve.

Inject Hyraulic Oil into the tool

using the priming syringe.

Indication Cause Solution

Tool installs rivet-nut

but strips thread on

Mandrel or inside the

rivet-nut.

The air pressure setting is too

high.

Adjust with the red knob lo-

cated on the base of the tool

Tool installs rivet-nut’s

erratically.

Usually because the air supply to

the tool is varying in pressure.

The tool functions pull-to-

pressure (air) Ensure a reliable

air supply.

The air motor runs

continuously after

installing rivet-nut.

The pressure on the reversing

valve is too heavy.

Adjust the reversing-spring ten-

sion located inside the reverse

button.

Tool remains engaged

with rivet-nut after

installation.

The air motor reverse period

needs to be extended.

Use a hex key in the bleed

valve. Adjust in 1/4 turn incre-

ments.

Insert will not engage

with the mandrel.

Usually a worn or damaged thread

on the Mandrel.

Replace with new Mandrel or

dress the thread.

Air escapes from the

relief valve.

The air supply pressure is too

high.

Reduce accordingly, MAXI-

MUM pressure is 7-bar (100psi)

The air motor runs

slowly.

Most times, the air motor needs

lubrication.

Drips a small quantity of Motor

Lubricating Oil in to the airline.

INTRODUCTION

The W12 is a cost-effective and reliable air rivet nut tool. It is suitable for both production and

project based installations due to the quick change mandrel system and the adjustable air pres-

sure stroke feature.

SAFETY INSTRUCTIONS

Caution! To ensure proper functioning and safe operation, read this Operator’s

Manual carefully before operating the RIVTEC® RT-W12 tool

■The W12 should be used exclusively to set rivet-nuts and rivet-studs.

■DO NOT overload the tool – work within the prescribed work capacity

■ALWAYS wear eye protection when working with the tool. Personal protection such as

clothes, gloves, safety helmet, non-slipping shoes, ear protectors and protection against

fall are highly recommended.

■This tool is NOT designed for use in explosive atmospheres.

■DO NOT use the tool as a hammer.

■Ensure the tool is not damaged before connecting to the air supply.

■Repair work must be carried out by trained personnel. In case of doubt, ALWAYS send

back the tool to the supplier.

■ALWAYS disconnect the air supply when adjusting, servicing or removing any part of the

tool.

■Keep ngers off the trigger when connecting the air supply or if the air supply fails.

■Keep ngers away from the front of the tool when connecting the air supply or setting

rivets.

■DO NOT point the tool at anyone.

■DO NOT operate tool with the nose housing removed.

■DO NOT modify the tool in any way. Modications could damage the tool.

■The operating pressure must not exceed 7 bar.

■Wash hands if exposed to hydraulic uid or lubricant.

■Keep hair, ngers and loose clothing away from moving parts of the tool.

This tool is designed to operate on clean, dry, regulated compressed air between 75 and

100psi. It is preferable to include an air lter, pressure regulator and automatic oiler within 4.5

metres of the tool if possible. An air lter is recommended to remove contaminates and mois-

ture that are contained in compressed air, ltering will signigantly prolong the life of the tool.

NOSE REPLACEMENT PROCESS

1. Disconnect the tool from the compressed air supply

2. Undo the Locking Ring from the Anvil.

3. Remove the Anvil with the Locking Ring from the nose assembly holder (the Locking

Ring remains on the Anvil)

4. Unlock and move the Front Sleeve forward.

5. Retract the spring loaded Security Part (7) towards the rear of the tool to release the

Mandrel.

6. In this position, release the Mandrel by turning it counter-clockwise.

7. In this position, screw the selected Mandrel until it stops by turning clockwise.

8. Release the Security Part (7) and ensure the retaining device covers the hexagon of the

Mandrel.

9. Push the Front Sleeve backwards and secure.

10. Screw the relevant Anvil with Locking Ring into the nose assembly holder.

11. Adjust the Anvil to the relevant material thickness then secure Locking Ring.

MAINTENANCE

Caution! Disconnect the air supply while relling the hydraulic oil. Keep the tool

upright during all operations.

Lubrication

It is important that the tool be properly lubricated. There may be insufcient oil if the stroke of

the tool is too small for proper installation of nuts/bolts. Without proper lubrication the tool will

not work properly and parts will wear prematurely. First check whether the stroke setting is

correct. Check the oil level indicator to see whether loss of oil has occurred. The tool has lost

oil if the oil level indicator pin no longer protrudes.

Adding Oil to your W12

1. Keep the tool upright during all operations. Disconnect the tool from the air supply.

2. Unscrew the cap screw from the body using the allen wrench included. Check whether

the O-ring remains in the hole.

3. Fill the syringe (included) with hydraulic oil.

4. Screw the lled syringe up to the O-ring in the hole. Then slowly inject the oil into the

tool (Make sure no air is injected) Adequate oil has been added as soon as resistance

is sensed. The excess oil will ow back when the syringe is release if more oil is added

than necessary.

5. Unscrew and remove the syringe from the body. Check whether the O-ring remains in

the hole.

6. Screw the cap screw into the hole using the allen wrench.

7. Wipe off any excess oil.
