Introduction

MBW equipment is intended for use in very severe
applications. The Vibration Suppressor is available in a
variety of configurations.

This parts manual contains only standard parts. Variations
of these parts as well as other special parts are not included.
Contact your local MBW distributor for assistance in
identifying parts not included in this manual.

Installation

• The MBW Vibration suppressor is intended to be
installed on a variety of pneumatic pole tampers.

• Connection adapters are included with some models to
add flexibility to installation

1. Disconnect air supply to tool and make sure all air
pressure is released

2. Unscrew connector pipe between trigger assembly
and main percussion unit

3. Attach “ROD” end of the Vibration Suppressor to the
main percussion unit. Tighten connection using a
supplied lock-nut

4. Attach trigger assembly to other end of the Vibration
Suppressor. Tighten connection using a supplied
lock-nut

• Depending on Pole Tamper style, adapters may be
needed to make connections

• To ensure connections stay tight, MBW recommends
using a medium strength thread locker on all
connections

• To lengthen the pole tamper assembly, it is
recommended that the added pipe section be placed
above the Vibration Suppressor

Before Starting & Operating

• REMEMBER! It is the owner’s responsibility to
communicate information on the safe use and proper
operation of this unit to the operators.

• Review ALL of the Safety Precautions listed on page 1 of
this manual.

distance from any moving parts.

• The MBW Vibration Suppressor should only be run with
clean and dry compressed air. The use of an oil mist
lubrication system will improve the life of both the
Vibration Suppressor and the pole tamper

• Verify that all joints are tight

Operating Ergo and Pole tamps

Follow all recommended operating procedures of
pole tamper manufacturer. Failure to do so could
result in serious bodily injury or death.

1. Connect air supply hose to trigger assembly

2. Grasp pole tamper assembly on the main body of the
Vibration Suppressor or anywhere above

3. Depress trigger to begin tamping.

4. Release trigger to stop device.

PINCH HAZARD: Avoid placing hands below main
body of the MBW Vibration Suppressor

• The MBW Vibration Suppressor is a spring loaded
device. Efficiency of isolation will depend on many
factors including air pressure, pole tamper type and
operator input. When operating, try to find the correct
down pressure that results in the least amount of
transmitted vibration.

Storage

• The MBW Vibration Suppressor is made of high quality
corrosive resistant components. To lengthen the life of
the entire tamper assembly, drop a small amount of light
oil into trigger assembly and run device for a minute
before long term storage.

Do not place any part of body above pole tamper
assembly. Device will “Jump” when air is
activated.
