Original Instructions

Welcome to the
Frontier family!
Congratulaons on the purchase of your new
Frontier sawmill. You made a great choice!
In 1993, Norwood introduced the world to
the very rst aordable portable sawmill: the
original LumberMate. That was a turning point.
Norwood opened a world of opportunies for
everyone — for outdoorsmen, crasmen, hard-
working families, hobbyists and professional
sawyers. Today, Norwood connues to lead
the sawmill revoluon: Norwood has over 85
patents, more than the rest of the industry
combined, and Norwood equipment is hard at
work in over 100 countries worldwide.
In 2017, Norwood launched Froner, an ultra-
aordable line of portable sawmills. In doing so,
even more hard-working families can unlock the
value in their trees by owning their own solid,
dependable and safe sawmill that they can be
proud of.
Both your Froner and you, as a Froner owner,
are part of the legendary Norwood legacy.
Norwood created all elements of the design
of your Froner using our high standards of
innovave engineering, leveraging several of our
patents. Your Froner is built to deliver hours of
producve and fun sawing.
Don’t forget to visit Norwood’s Sawmill.TV, our
on-line “TV” channel dedicated to sawmills and
successful sawmilling. It is a great resource to
learn everything from how to get started, to
advanced sawmilling techniques, to bite-sized
tech ps.
Thank you for placing your trust in us. We’re
right behind you to help you make the most of
your new Froner sawmill. We wish you all the
best with your sawmilling journey.

DISCLAIMER
Norwood Industries Inc. & Norwood Sawmills
U.S.A. Inc. disclaim any responsibility or
liability, in negligence or otherwise, for any
injuries, damages or losses of any kind arising
during the course of assembling, operating or
handling this equipment, options, accessories
or blades howsoever caused.
Responsibility for final inspection of the
Frontier OS parts and components, and the
assembly, maintenance and safe use of the

in this manual, apply both during and after the one-year
term of this Warranty.
Entire Written Warranty: This Warranty is the only
and the entire written warranty given by Norwood for

and a safety limit switch installed on the rear guard. The
machine cannot operate without these protections in
place. Test the safety limit switch once a day: Remove
the front cover and attempt to start the engine. If the
engine starts, the safety limit switch is not working;
therefore, stop using the equipment and contact
Frontier Sawmills immediately to order a replacement
(Part # FRON-SFTY1).
A–6

Bed End Stops
These mechanical stops prevent the carriage from
rolling off the tracks. Inspect once a day that the end
stops are in place and not damaged. If one of the end
stops is missing or damaged, stop using the equipment
and contact Frontier Sawmills immediately to order a
replacement (Part # OS18-B0014 in OS18-BOX #2).

permanently impaired after only short
exposure to high-frequency sounds.
Wear approved close-fitting safety goggles
when working with the equipment or handling
blades.
Wear approved protective footwear with saw
protection, steel toe-cap and non-slip sole
when working with the equipment or handling
blades.
Wear full-length protective pants when working
with the equipment or handling blades. Never
wear loose-fitting clothing, scarves, jewelery or
similar long items that can get caught when
working with the equipment. Always secure loose hair
before working with the equipment.
Wear respiration protection when working with
the equipment. Long term inhalation of
sawdust and the engine’s exhaust fumes can
represent a health risk.
The Worksite
AOperate the equipment and handle blades in full
daylight or under adequate site lighting cast from at
least four sides to minimize shadows.
AKeep the work area clean, free of clutter, pets,
children, obstacles, hazards or distractions.
AKeep all children and animals well away from the
equipment and blades at all times.
AA broken blade can be ejected out of the sawdust
chute at high velocity. Keep all people and pets
completely clear of the path of the sawdust chute.
Remember that, as the carriage moves, so do the
blade and the path of the sawdust chute.
AThe risk of blade breakage increases when a blade
is not properly and regularly profiled and maintained
and/or when a blade is used past its service life.
AIllustration below depicts view of work site as
seen from above. It sets out the minimum safety
distance for persons other than the operator. While
operating the equipment, the operator must be within
the stipulated area* bounded between the broken
line and the nearest side of the sawmill.
AWhile the equipment is running, persons other than
the operator must observe the safety distances
stipulated in the illustration.
AThe minimum safety distance away from the
equipment for persons other than the operator on
the left side of the sawmill (the side opposite the
operator’s side) is 15 m (50 ft) due to the risk of
blades being ejected out of the sawdust chute. On all
other sides of the equipment, the minimum distance
away from the equipment for persons other than the
operator is 6 m (20 ft).

AKeep hands, limbs and all body parts completely
clear of the blade, cables and any other moving
parts. Remember that, as the carriage moves, so do
the blade, cables and other moving parts. Keep clear
of all danger areas.
ANever operate the gasoline (petrol) powered engine
in enclosed areas. Operate the gasoline-powered
engine only outside in a well-ventilated area. The
exhaust gases of the engine can cause nausea,
delirium, and potentially death unless adequate
ventilation is present.
ARisk of being crushed by the carriage.
ARisk of tripping on the tracks or the cross-bunks.
ANever walk on the tracks or the cross-bunks.
ANever step across the tracks.
ARisk of being crushed between the sawmill and a
moving log.
ASet up the equipment on level ground so that there is
at least 3 m (10 ft) of level ground around the tracks
and that there are no obstacles within that area.
ADo not stand between the pile of logs and the
equipment.
AAlways stand at the side of the pile of logs when
handling the logs. Never stand where you are at risk
of being hit by a rolling log.
AKeep at least a 5 lb fully-charged ABC dry-chemical
fire extinguisher visible and easily accessible at the
worksite.
AKeep a fully-stocked first-aid kit visible and easily
accessible at the worksite.
ANever work alone. Make sure that there are other
adults within hearing distance should you need to
call for help.
Operating the Equipment
ACutting tools: Stand behind the carriage and keep
both your hands on the push handle while operating
the equipment. Never stand in front of the carriage or
blade. Never pull the carriage through the cut.
ASawhead drop danger: Pressing downward, even
slightly on the winch brake tensioner assembly, will
release the winch brake. Releasing the winch brake
will cause the sawhead to drop quickly and violently
and may cause serious injury.
AThe clutch mechanism is extremely sensitive: Even
the slightest touch on the throttle handle weldment of
the push handle assembly, when the engine is idling,
can engage the clutch and thereby cause the blade
to spin. Never open the front cover while the engine/
motor is running.
ABefore opening the front cover, turn the engine ON/
OFF switch to the "OFF" position and shut the fuel
off at the engine. Consult your engine manual for
safe shutdown procedures to prevent accidental
ignition. If your sawmill is equipped with an electric
motor, also disconnect (unplug) the power supply
electrical cable from your electrical outlet.
ACoiled blades can spring apart with considerable
force and unpredictably in any direction. Handle
coiled blades, including those packaged in boxes,
with the utmost care.
AThe front cover is shatter resistant to temperatures
as low as -20 °F (-28 °C). Never operate the
equipment in temperatures at or below -20 °F (-28 °C).
AEnsure that the equipment is assembled and
maintained in accordance with this manual, the
engine manual and the instructions enclosed with
optional accessories.
ANever use the equipment to cut anything other than
clean logs or lumber.
ANever add hardware or attachments of any kind
to the equipment other than those manufactured
by Norwood Industries Inc. specifically for the
equipment. Never modify the equipment.
Before operating the equipment, ensure that:
»all maintenance procedures have been properly
carried out;
»the blade is disengaged;
»the equipment stands firmly and securely and the

ATurn the engine/motor off if you are going to leave
the operating station behind the carriage, even
just temporarily, for example when loading or
repositioning logs or removing lumber.
Burn danger! The engine and muffler get very
hot during operation and remain very hot for a
long time after operation. Do not touch.
ANever overreach. Keep proper footing at all times.
ADiscontinue operating the equipment or handling
blades if you become fatigued or distracted.
AStay focused and alert. Watch what you are doing.
Use common sense.
AMoving parts! In case of broken blade or belt, the
bandwheels may keep turning for an extended
period of time. The operator must wait for the
bandwheels to come to a complete stop before
leaving the operating station behind the carriage.
Never attempt to shorten the deceleration time of the
bandwheels by grabbing them with your hands or
using an intermediate tool to do so. Never approach
the front of the carriage or attempt to open the front
cover while any parts are moving.
ABefore releasing the push handle or not otherwise
holding the carriage, secure the carriage against
uncontrolled movement along the track by engaging
the carriage stop latch assembly.
ARefuel before operating the sawmill when the engine
is cold; never refuel when the engine is hot.
When operating the gasoline (petrol) powered engine:
Fire danger! Gasoline, its vapors and oil are
extremely flammable. Burn injuries can be
life-threatening.
ANever operate the gasoline (petrol) powered engine
with a fuel or oil leak. The leaking fuel or oil could
potentially come in contact with hot surfaces and
ignite into flames. If you spill fuel, turn off the engine
immediately and clean the area right away. If you get
fuel on your clothing, change immediately.
ATo avoid fire or explosion, never smoke while
refueling or handling fuel. Never permit smoking,
welding, grinding, blade sharpening or any sparks or
flames near the engine, fuel tanks or fuel.
ATo avoid fire or explosion, always turn the engine off
before refueling.
ARefuel before operating the sawmill when the engine
is cold; never refuel when the engine is hot.
If your sawmill is equipped with an electric powered
motor:
Risk of electric shock! Hazardous voltage
inside the disconnect box, starter box and at
the electric motor can cause shock, burns or
death.
AElectrical short danger! Ensure that you do not short
out any part of the electrical system. Shorting out
the electrical system can cause both of the sawhead
support cables to simultaneously break suddenly
and the sawhead to drop violently causing serious
injury.
AAlways keep the terminals protected by plastic/ a lid.
ANever short out the positive and negative terminals
on the battery. Do not allow any metal objects to
come into contact with the positive and negative
battery terminals such that it could cause an
electrical short.
ARoutinely inspect the battery cables for wear. Any
break in the insulating casing of the battery cables
creates a risk of electrical short.
AOnly a qualified electrician can open the electrical
equipment. All electrical installation, service and
maintenance work must be performed by a qualified
electrician and must be performed in accordance
to applicable electrical codes. Failure to do so can
A–9

result in serious injury or death.
ABefore installing, servicing or maintaining any of
the electrical equipment, turn the ignition switch to
the "OFF" position and remove the ignition switch,
disconnect the sawmill battery ground terminal and
disconnect (unplug) the power supply electrical
cable from your electrical outlet. Follow all applicable
electrical codes.
AIf you have any reason to suspect that there
is anything wrong with the electrical system,
immediately disconnect (unplug) the power supply
electrical cable from your electrical outlet, turn the
ignition switch to the "OFF" position and remove
the ignition key, disconnect the sawmill battery
ground terminal and contact a qualified electrician to
service the electrical equipment. Do not operate the
equipment until it has been serviced by a qualified
electrician and certified fully safe to operate.
AUse the proper battery, 12 volt with a minimum of
330 C.C.A. Connect the RED battery cable to the
positive terminal of the battery, tighten securely. Then
connect the BLACK battery cable to the negative
terminal of the battery, tighten securely.
Maintaining the Equipment
AAlways ensure that all the equipment, its
components, fasteners, cables and parts are
properly maintained and adjusted and in good
working order before operation.
ABefore performing any service, maintenance,
cleaning, repairs or adjustments, before opening
the front cover, before removing or installing blades,
before moving the sawmill and before storing the
equipment, turn the engine ON/OFF switch to the
"OFF" position, and shut the fuel off at the engine.
Consult your engine manual for safe shutdown
procedures to prevent accidental ignition. If your
sawmill is equipped with an electric motor, also
disconnect (unplug) the power supply electrical cable
from your electrical outlet.
ABefore performing any service, maintenance,
cleaning, repairs or adjustments, before opening
the front cover, before removing or installing blades,
before moving the sawmill and before storing the
equipment, lower the sawhead to its lowest position.
AOnly service the engine before operating the sawmill
when the engine is cold; never service the engine
when the engine and muffler are hot.
AKeep operating handles dry, clean and free of oil.
ANever clean the saw blade or bandwheel on this
equipment while the blade, bandwheel or any parts
are in motion.
AIf you need to disassemble some parts, keep them
all together in one box and ensure that, when you
reassemble them, you do so correctly, use all of the
parts and that the box is empty.
AUse only original parts from Frontier Sawmills.
Moving the Equipment
Before moving the sawmill, make sure that all parts are
securely fastened and will not fall or be lost. Keep all
loose parts together in a box to make sure the parts are
not lost.
The saw carriage and the bed must not be lifted or
transported simultaneously; the saw carriage and the
bed must each be lifted and transported separately and
by forklift truck or the like.
ARisk of being crushed by the carriage and bed.
Keep all people and pets at least 6 m (20 ft) from
the equipment while it is being loaded, suspended,
moved and unloaded.
ADanger of tipping. Do not transport on uneven
terrain.
ABefore moving the sawmill, lower the sawhead to its
lowest position.
Lifting the saw carriage: Disconnect the carriage
retaining brackets and lift the saw carriage with reliable
straps securely affixed to both carriage lifting plates
located at the top of the saw carriage. Use the carriage
lifting plates shown on the “Overall View” at the front of
this manual.
Lifting the bed: Lift the bed slowly and carefully with the
use of forks of a forklift truck or the like positioned under
the bed tracks. Place a protective layer of wood securely
on the top surface of the lift forks. Centered along the
side of the bed, insert the forks all the way under the bed
so that both tracks are securely balanced and supported.
Securely strap the tracks to the lift forks.
See the “Technical Data” section in this manual for
equipment weights.

Storing the Equipment
AWhen storing the equipment, turn the engine ON/
OFF switch to the "OFF" position, shut the fuel
off at the engine and remove the blade. Consult
your engine manual for safe shutdown procedures
to prevent accidental ignition, and take any other
measures necessary to prevent unauthorized
operators from accessing or starting the equipment.
If your sawmill is equipped with an electric motor,
also disconnect (unplug) the power supply electrical
cable from your electrical outlet.
AEnsure that the front cover is correctly installed and
securely locked.
ALower the sawhead to its lowest position.
AAlways store the equipment in a secure and locked
location completely inaccessible by children or any
persons.
AWhen not in use or when unattended, even for short
periods of time such as during breaks, remove the
blade from the sawmill and store it in a location
inaccessible by children or any persons. In addition
to being a wise safety precaution, removing the
blade from the sawmill ensures that it is not stored
under tension and so prevents premature blade
fatigue.
AWhen not in use, secure the carriage to the bed
with the carriage stop latch assembly to prevent the
carriage from being blown or inadvertently rolled
along the track.
AAlways store all blades in a secure and locked
location completely inaccessible by children or any
persons.

* Typical distribution measurements for vibration levels at the push handle at 1 m/s2. The above sound level figures quoted are
emission levels and are not necessarily safe working levels. Whilst there is a correlation between the emission and exposure levels,
this cannot be used reliably to determine whether or not further precautions are required. Factors that influence the actual level
of exposure of the workforce include the characteristics of the work room and the other sources of noise etc. i.e. the number of
machines and other adjacent processes. The permissible exposure level can also vary from country to country. This information,
however, will enable the user of the machine to make a better evaluation of the hazard and risk.
