CAUTION:
Make sure that the throttle lever is moved to the
FULL OPEN position. Operating the rammer at
less than full speeds can result in damage to
the clutch springs or foot
2. The MT-74FA tamping rammer is designed to run at 4,000
rpm. At optimum rpm the foot hits at the rate of 680 impacts
per minute. Increasing throttle speed past factory set rpm
does not increase impacts and may damage unit. The
MT-74FA is designed to advance while tamping. For faster
advance, pull back slightly on the handle so that rear of foot
contacts soil first.

the FULL OPEN to IDLE position.
