1.2 Sawmill Setup
WARNING! Put front outrigger down before moving cutting
head from the rest position. Failure to do so may result in
serious injury.
WARNING! Do not set up the mill on ground with more than
a 10 degree incline. If setup on an incline is necessary, put
blocks under one side of the mill or dig out areas for outrig-
ger legs to keep mill level. Setting up the mill on an incline
could cause it to tip over, resulting in serious personal
injury.
WARNING! Chock the trailer wheels to prevent movement
before unhitching it from the towing vehicle. Failure to do so
may result in serious injury or death.
WARNING! Always make sure the trailer is supporting the
sawmill frame when operating a sawmill with adjustable
outriggers. Failure to do so may result in serious injury or
death. The adjustable outriggers are intended to support
the saw frame with assistance from the trailer.
WARNING! The adjustable outriggers supplied with porta-
ble sawmills are not intended for setup on concrete or other
hard surfaces. Long-term use of the adjustable outriggers
on hard surfaces may cause the outriggers to fail, causing
the sawmill to drop. This could result in possible serious
injury or death.
If setting the sawmill up on concrete or other hard surface,
replace the adjustable outrgger legs with stationary legs.

1.3 Sawmill Operation
DANGER! Never operate or tow the sawmill without all
guards and covers in place and secured.
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 disengage the clutch/brake mechanism
whenever the sawmill is not cutting.
DANGER! Always keep hands away from moving bandsaw
blade.
DANGER! Keep all persons a safe distance away from
work area when operating sawmill or loading and turning
logs.
DANGER! Be sure the power feed switch is in the neutral
position before turning the key switch to the ON or ACC
position. This prevents unwanted carriage movement.
DANGER! Check to be sure the saw head is resting firmly
on the rest pin and mast rail stops and that the safety chain
is secured before towing the sawmill.
WARNING! Always secure the cutting head with a 5/16”
chain before adjusting the up/down chain. The cutting head
may fall, causing severe injury or death.
WARNING! Always secure the cutting head with a 5/16”
chain before removing the up/down motor belt. The cutting
head may fall, causing severe injury or death.

decals. Contact your local distributor, or call your Customer
Service Representative to order more decals.
CAUTION! Be sure the pivot rails, turning arm, clamp, and
toe boards are out of the way before loading a log onto the
bed. Also, be sure the cutting head is moved far enough
forward so the log does not hit it.
CAUTION! It is important that the lower stop bolts are prop-
erly adjusted to secure the carriage on the track rail. Failure
to properly adjust the stop bolts can cause saw head dam-
age, especially during mill transportation.
IMPORTANT! It is always the owner's responsibility to
comply with all applicable federal, state and local laws,
rules and regulations regarding the ownership, operation
and towing of your Wood-Mizer sawmill. All Wood-Mizer
mill owners are encouraged to become thoroughly familiar
with these applicable laws and comply with them fully while
using or towing the mill.
Always properly dispose of all sawing byproducts, including
sawdust and other debris.
