Sawmill Operation

DANGER!

Make sure all guards and covers are in place

and secured before operating or towing the sawmill. Failure
to do so may result in serious injury.

Be sure the blade housing and pulley covers are in place
and secure. Use the safety retainer pin and cable to fasten
blade housing covers.

DANGER!

Always keep hands away from moving bandsaw

blade. Failure to do so will result in serious injury.

DANGER!

Stay clear of the area between the trailer axle

and saw carriage. Failure to do so will result in serious
injury.

DANGER!

Keep all persons out of the path of moving

equipment and logs when operating sawmill or loading and
turning logs. Failure to do so will result in serious injury.

DANGER!

Maintain a clean and clear path for all necessary

movement around the mill and lumber stacking areas. Fail-
ure to do so will result in serious injury.

DANGER!

Always be sure the blade is disengaged and all

persons are out of the path of the blade before starting the
engine or motor. Failure to do so will result in serious injury.

DANGER!

Keep all persons out of the path of returning

boards. Failure to do so will result in serious injury.

WARNING!

Always disengage the clutch/brake mechanism

whenever the sawmill is not cutting. Failure to do so may
result in serious injury.

WARNING!

Always wear eye, ear, respiration, and foot pro-

tection when operating the sawmill. Failure to do so may
result in serious injury.

WARNING!

Be sure the power feed switch is in the neutral

position before turning the key switch to the on (#1) or
accessory (#3) position. This prevents accidental carriage
movement

which may cause serious injury or death.
