PERATION
Introduction
MBW equipment is intended for use in very severe
applications. The Airammer is powered by a pneumatic
motor and is available with different size tamping shoes.
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.
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.
• Familiarize yourself with the operation of the machine
and confirm that all controls function properly.
• Know how to STOP the machine in case of an
emergency.
• Make sure hands, feet, and clothing are at a safe
distance from any moving parts.
Motor Lubrication
Oil lubrication must be supplied to the Airammer at all times
during operation. Operating the Airammer without
lubrication will cause damage to the pneumatic motor.
If the supply hose from the compressor to the Airammer is
less than 50’ long, the oiler on the compressor should be
sufficient.
If the supply hose is longer than 50’, a high volume in-line
oiler should be installed near the Airammer. Do not install
the oiler on the Airammer handle. The air lubrication system
should supply 1/2 oz of oil for every 8 hours of operation.
Use suitable air tool oil such as Exxon Spinesstic 10,
Atlantic Richfield Duro 55, Gulf Gulfspin 10, or any other
equivalent.
Connecting to Air Compressor
For proper operation, the Airammer requires a compressed
air supply of at least 75 cfm at 110 psi.
1. Start compressor and check pressure gage to verify
proper operation of the compressor.
2. Connect air hose to compressor outlet and install
safety clips if required.
3. Connect air hose to Airammer coupler and install
safety clips if required.
4. Open compressor valve to pressurize Airammer.
Operating
CAUTION
Always wear safety goggles and hearing protec-
tion when operating Airammer.
1. Squeeze the Airammer actuator handle and check
the Airammer pressure gauge.
2. If the pressure reading is less than 100 psi (indicated
as a red section on some gages), the air pressure at
the source must be increased.
3. On uneven terrain, pushing down on the handle will
aid climbing ability.
CAUTION
Do not bear down (body weight of operator) on
the machine.
4. After three passes, the rammer may have more kick
back. This is an indication that ideal compaction is
being reached.
Motor Icing
If the Airammer is operated for long periods of time or in a
high humidity environment, frost will form on the motor. This
is normal and will not harm the motor. If the motor should
“freeze up” from icing, allow it to thaw before continuing use.
Ensure there is adequate oil supply to the motor.
