lever (Figure 9) quickly from IDLE to the START ( )
position. DO NOT move the throttle lever slowly as this
may cause damage to the clutch or spring.
Figure 9. Throttle Lever (Start Position)
2. The MTX70HF tamping rammer is designed to run
at 3,800 to 4,100 rpm. At optimum rpm the foot hits
at the rate between 590 - 695 impacts per minute.
Increasing throttle speed past factory set rpm does
not increase impacts and may damage unit. The
MTX70HF is designed to advance while tamping. For
faster advance, pull back slightly on the handle so that
rear of foot contacts soil first.
3. To stop the tamping action, move throttle lever quickly
from START to IDLE position (Figure 6).

position (Figure 6) and run the engine for three minutes
at low speed. After the engine cools, move the throttle
