SECTION 1 GENERAL INFORMATION
IMPORTANT! This manual is provided as a supplement to
the equipment manufacturer’s manuals. Refer to the
manufacturer’s manual before attempting to operate this
equipment.
This symbol calls your attention to instructions concerning your personal safety. Be sure
to observe and follow these instructions. This symbol accompanies a signal word. The
word DANGER refers to hazards that can cause death or serious, irreversible personal
injury. WARNING suggests a potentially hazardous situation which, if not avoided, could
result in death or serious injury. CAUTION refers to potentially hazardous situations
which, if not avoided, may result in minor or moderate injury to persons or equipment.
1.1 Safety
DANGER! If the sawmill with the trailer is unhitched from a
towing vehicle, then the sawmill should be secured through
placing wedge blocks under the wheels.
DANGER! Chock the trailer wheels to prevent movement
before unhitching it from the towing vehicle.
DANGER! Be sure that the hitch and safety chains are
secure before towing the sawmill. Check all lights and
signals for correct operation.
DANGER! Always check trailer tires for proper inflation
before towing sawmill.
DANGER! Always keep away from trailer axle to avoid
being caught between the axle and moving saw carriage.
