MB156 User Manual ◄ 7
• Do not operate the tool unless thoroughly trained or
under the supervision of an instructor.
• Become familiar with the carrier controls before op-
erating the carrier and the breaker.
• When operating the breaker you must use ear pro-
tection, eye protection, and breathing protection.
• While learning to operate the breaker and carrier, do
so at a slow pace. If necessary, set the carrier mode
selector to the slow position.
• Make sure all controls (levers and pedals) are in the
NEUTRAL position before starting the carrier.
• While operating the breaker and carrier, keep hands
and feet on the controls at all times.
• Before leaving the carrier, always lower the boom
and insure the carrier is stable. Never leave the ma-
chine with the engine running. ALWAYS ENGAGE
THE PARKING BRAKE.
• Stop the engine before attempting to make any re-
pairs, adjustments or servicing to either the carrier
or the breaker.

190 °F/88 °C. Operation at higher temperatures
can damage the internal components of the breaker

formance.

justed, or incompletely assembled breaker.
• Do not modify the breaker in any manner.
• Use only tool bits supplied by Stanley Hydraulic
Tools. Use of tool bits supplied by another manu-
facturer may damage the breaker and will void the
warranty.

breaker repair, maintenance and service must only
be performed by authorized and properly trained
personnel.
• If you do not understand how to safely operate your
breaker, contact an authorized Stanley Dealer for
assistance.

ication which may affect your mental judgement or
