Engaging or Disengaging Cutter Wheel at High Engine Speed Can Cause Personal Injury and Machine Damage.
Always Disengage Before Turning Machine On/Off.
• Reduce engine speed to idle.
(Approximately 1000-1200 RPM)
• Raise cutter wheel clear of stump.
• Engage cutter wheel by lifting the slide
lock lever and pulling the engagement
handle toward the engine slowly enough
to prevent stalling the engine. (Refer to
illustration)
• Bring the cutter wheel to speed by
controlling the engagement handle to
slowly engage the cutter wheel. If handle
is engaged to quickly or at high engine
speed, belt, sheave, and/or engine
damage could occur.
• With the cutter wheel fully engaged, you
can now move the engine throttle to the
preferred engine operation position.
• Test controls for proper operation,
speed, and unobstructed movement.
• Cutter head swing speed should be
adjusted to a rate that will allow cutter
wheel to pass through stump smoothly.
If jerking, bouncing or significant drops
in engine speed occur, swing rate is too
rapid and must be decreased.
• Swing speed should be determined and
adjusted with the controls in the full
open position.
• A bypass flow control valve is located
within the hydraulic system to adjust this
speed. Turning the handle counter-
clockwise will open the bypass and slow
swing action. Turning it clockwise will
increase swing rate.
