SECTION 1 SAFETY & GENERAL INFORMATION
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 DAN-
GER indicates an imminently hazardous situation which, if not avoided, will result in death or seri-
ous 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. Read all safety instruc-
tions before operating this equipment and observe all safety warnings!

1.1 Blade Handling
DANGER! Always disengage the blade and shut off the sawmill
engine before changing the blade. Failure to do so will result in
serious injury.
WARNING! Always wear gloves and eye protection when han-
dling bandsaw blades. Changing blades is safest when done by
one person! Keep all other persons away from area when coiling,
carrying or changing a blade. Failure to do so may result in seri-
ous injury.
WARNING! Do not spin the blade wheels by hand. Spinning the
blade wheels by hand may result in serious injury.
1.2 Sawmill Setup
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! Failure to put front outrigger down before moving
cutting head from the rest position may result in serious injury.
WARNING! Securely fasten the feet of a stationary sawmill to
the floor before operating the sawmill. Failure to do so may result
in serious injury or death.
WARNING! Always make sure the trailer is supporting the saw-
mill frame when operating a sawmill with adjustable outriggers.
Failure to do so may result in serious injury or death. The adjust-
able outriggers are intended to support the saw frame with assis-
tance from the trailer.
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 outrigger legs to
keep mill level. Setting up the mill on an incline could cause it to
tip over, resulting in serious personal injury.
CAUTION! Changes in temperature could cause increased
pressure in the blade tensioner and loss of fluid from the gauge.
Release the blade tension when the mill is not in use to avoid
damage to the tensioner.

1-3 HDSdoc091108 Safety & General Information
1.3 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. Fail-
ure 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. Failure to
do so will result in serious injury.
DANGER! Always be sure the blade is disengaged and all per-
sons 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 protec-
tion when operating the sawmill. Failure to do so may result in
serious injury.
WARNING! Be sure the power feed switch is in the neutral posi-
tion 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.
WARNING! Secure all loose clothing and jewelry before operat-
ing the sawmill. Failure to do so may result in serious injury or
death.

WARNING! Always make sure log is clamped securely before
sawing. Failure to do so may result in serious injury or death.
WARNING! Always leave loading arm halfway up while log is on
sawmill bed. Failure to do so may result in serious injury or death.
WARNING! The automatic board return is intended to assist a
second operator in removing boards quickly. Do not use the
board return when operating the sawmill alone. Serious injury,
death or damage to the equipment may result.
WARNING! Never use the board return table as a platform to
stand on. This table is designed and intended to assist in the
removal of boards only. Standing on the table may result in seri-
ous injury.
WARNING! Use ONLY water with the water lube accessory.
Never use flammable fuels or liquids. If these types of liquids are
necessary to clean the blade, remove it and clean with a rag. Fail-
ure to do so may result in serious injury or death.
CAUTION! Be sure the pivot rails, turning arm, clamp, and toe
boards are below bed level before loading a log onto the bed.
Failure to do so may result in machine damage or cause mis-
alignment.
CAUTION! Before loading a log, be sure the cutting head is
moved far enough forward so the log does not hit it. Failure to do
so may result in machine damage.
CAUTION! Always make sure the engine is running before oper-
ating the hydraulic controls. Operating the controls without the
engine running will result in power drainage from the battery.
Holding the hydraulic switches halfway up or down also will cause
excessive drainage from the battery.
CAUTION! Avoid leaving hydraulic contacts engaged while
machine is not being operated. Battery drainage may result!
CAUTION! Be careful when manually lowering the log loader.
Do not drop the loader onto the ground or perform any action
which might break the velocity fuse valves on the loader cylin-
ders. These valves control hydraulic flow and are necessary to
prevent the loading arm from collapsing during use.
CAUTION! Do not try to force the saw head beyond its upper
and lower travel limits. Damage to the up/down system may
result.

1-5 HDSdoc091108 Safety & General Information
CAUTION! Always make sure the up/down switch moves to the
neutral or off position when released to ensure that the saw head
stops moving. Failure to do so may result in machine damage.
CAUTION! If the weight of the sawmill exceeds 3,000 lbs (1361
Kg) for any reason, an auxiliary braking system (such as electric
brakes) must be used. Failure to do so may result in severe
machine damage.
CAUTION! Move the hydraulic clamp and turner to provide max-
imum ground clearance before towing. Failure to do so may result
in damage to the sawmill.
CAUTION! Be sure to stop the blade when returning the car-
riage. This will not only prevent the blade from being pulled off
and ruined by a wood sliver, but also will increase the life of the
blade.
CAUTION! The sawmill’s work-stand should be equipped
with a 4 kg or bigger dry powder extinguisher.
1.4 Sawmill Maintenance
WARNING! Always secure the cutting head with a chain or a
brace before adjusting the up/down chain. The cutting head may
fall, causing severe injury or death.
WARNING! Always secure the cutting head with a chain or a
brace before adjusting the mast pads. The cutting head may fall,
causing severe injury or death.
WARNING! Always secure the cutting head with a chain or a
brace before removing the up/down motor belt. The cutting head
may fall, causing severe injury or death.
WARNING! Drum switch grease contains Petroleum Hydrocar-
bon Lubricant. Eye and skin irritant. If introduced into eyes, flush
with water for at least 15 minutes. If film or irritation persists, seek
medical attention. Wash skin with soap and water. If ingested, do
not induce vomiting - contact a physician. KEEP OUT OF THE
REACH OF CHILDREN.
CAUTION! Do not over-grease the blade guide bearings.
Over-greasing will push the seals out of the bearings causing pre-
mature failure.
CAUTION! Reinstall the track wiper so that it lightly touches the
track rail. If the wiper presses too firmly against the rail, it can

cause the power feed to bind.
CAUTION! Never use grease on the mast rails as it will collect
sawdust.
CAUTION! Do not use chain lube. It causes sawdust buildup in
chain links.
CAUTION! Do not over-tension the up/down chain. Over-ten-
sioning may lead to early failure of the gear reducer.
CAUTION! Do not overtighten the feed chain. Damage to the
power feed motor may result.
CAUTION! Do not overtighten the contact set screws on the
hydraulic valve assembly. Overtightening may cause the threads
in the screw hole to strip.
CAUTION! Due to variations in the vertical mast, the pad spac-
ing may vary throughout the travel of the saw head. Check the
pad spacing at the top and bottom ends of the mast only. Pads
adjusted too tight will cause premature up/down motor failure.
CAUTION! It is important that the lower stop bolts are properly
adjusted to secure the carriage on the track rail. Failure to prop-
erly adjust the stop bolts can cause saw head damage, especially
during mill transportation.
CAUTION! Pressure should not exceed 2000 psi. If it does, the
amp draw will rise above the design maximum of 200 amps, and
could cause battery and system problems. Pressure above 2000
p.s.i. may also damage the hydraulic hoses.
CAUTION! Failure to remove sawdust buildup from the battery
box lid and/or track rail cover could result in damage to these
parts when the saw head is lowered to its lowest position.
